PERIODICIL: Elektrichestvo, 1958, Nr 6, PP. 33-36 (USSR)
LBSTRACT: Problems of the calculation of voltage wave distortions
in the formation of a discharge in a long air-gap are in.-
vestigated here. The rules governing the change of the
current prior to the discharge are the most important of
these problems. First the method of investigation is gi-
ven. A generator for pulse voltages of 3 mV and a capacity
in the discharge of 36oo and 72oo uF was used in these in-
vestigations. It is shown that the measurement of the cur-
rent before the discharge with connecting the shunt between
plane and earth gives practically the same results as the
measurement from the side of the grounded rod when bringing
Card 1/4 the voltage wave of negative polarity to the plane. Accor-

i
Distortion of the Voltage Wave in the Formation 105-58-6-8/33
of a Discharge in a Wide Air-Gap
ding to authorst opinion, this method is equivalent to
that of connecting the shunt on the side of the high-
-voltage-electrode of the positive rod and at the same
time it is essentially more simple since no measuring-
-instruments for high potential are reuqired. In order
to determine the distortion of the voltage wave, the de-
pendence of this current on the voltage must be known.
Numerous tests with different forms of the applied vol-
tage wave were carried out for the purpose of determining
the connection between the current prior to the discharge
and the voltage in the discharge-gap between the positive
rod and the plane. It was found that the current prior to
the discharge is approximately expressed by the formula
(1). This formula renders correctly the physical aspect
of the phenomenon. The current prior to the discharge
takes place under the condition that the voltage in the
gap exceeds the break-down voltage of the gap-part which
is not disturbed by the leader (lider). The dependence

velocity of development of the discharge-leader with an
instantaneous voltage-value in the discharge-gap and the
length of that part of the gap which is not disturbed by
the leader-canal, as well as the formula (1) make it
possible to determine - by way of calculation - the form
of, the voltage wave distorted by the process before the
break-down and the corresponding discharge-time of the
generator of the tapulse-voltages on the air-gap- if the
wave-shape with the free-motion of the generator (non-
distorted wave) is known. Neglecting the reactance in
the discharge-circuit, the calculation presents no diffi-
culties and is carried out according to the method of the
successive intervals, analogous to the calculation of the
leaaer-velooity and to the time prior to the discharge in
reference 2. The measurements carried out according to
the method given here furnish a satisfactory conformity
with the test-for unipolar waves of different form.

Shape (Skhoma dlya poluoheniya voln napryatheniya spetsialvnoy

PERIODICAM Elektrichestvo, 1959, Nr 6, PP 76-77 (USSR)
ABSTRACT: In the praotical work of high-voltage laboratories there arises
often the need of testing different insulations under the
action of pulsed voltages of standard shape (1-5 - 3140-50AGG,))
and of other shapes as shown in figure.l. A unipolar wave with
a superimposed high-frequenoy oscillation (Fig 1b) and a
partly olipped wave (Fig !c) are shown. The circuit presented
in figure la is the simplest one giving such waves. It is also
used in the Laboratory of Exceseive Voltages of the VEI ~
It only requires a spark gap IF and "induction coil L, which
is connected to the voltage U, 0 This voltage equals the
amplitude of the superimposed oscillations. The mode of action
is very simple. if the pulse generator trips the voltage across
the spark gap rises to U
. The spark gap breaks down and in the

Where n is the number of condensers

The inductivity of the induction coil is chosen according to
the desired oscillation frequeney. The voltage of the
oscillatory circuit and the voltage of the non-shunted paTt of
the pulse generator add and delliver a wave with superimposed
oscillations at the output (Fig 11b). if a 7ery small attenuation
of the high-frequen(ty oscillations is required, the damper
winding R in the shunted part of the pulse generator must be
shortened. If it is necessary that the spark gap trips without
retardation, which is reqvired M most nases, the use of
spherical electrodes ot -a suitable diameter Is recommended. The
generation of a partly clipped wave is even simpler. In this
case no tnduotion coil is required and the corresponding lower
part of the pulae generator is shunted only by the spark gapy

obtained with a 3000 kv pulse generator of the VEX by using the
method presented herein. There are 2 figures.

TEXT: Tests were made on 500 kV air circu1t-breaker3 type
88HP -20001-500/2000 (VVNR-20001-500/2000) with a rated current Of

The circuit breaker is developed for a recovery voltage of
3.5 Uphase :: 1160 kV effective with a maximum.formation-time-of
10 milliseconds. According to test laboratory data the
disconnector was of reduced electric strength, 2-7 U phase 820 kV

effective instead of 3-5 Uphase 1" 1160 kV effective. The principal
object of the test was to determine the possibility of doing
without shunting resistors of 3000-2000 ohms on the main extinction
chambers. These resistors greatly increase the cost of the
circuit breakers (1-5 tons of nichrome for a three-phase set) and
according to data from preliminary tests on models, they are
effective in reducing the overvoltage only when disconnecting
unloaded sections of line accompanied by recurrent restriking of
the arc in'the circuit breaker. Tests were carried out with the
circuit shown in the sketch using a reduced working voltage of
430 kV on the receiving end of the transmission line U8. The
main tests were carried out on circuit breaker BB (sub-station
no.2). Protective spark gaps were used to limit Re value of the
overvoltage. To assess'the part played by the electromagnetic
instrument voltago,-transformers when disconnecting an unloaded
line between substations nos. 2 and 4, 'all three voltage
transformers were connected in ihe red phase, only two in the
green phase and none in tho yellow phase. Overvoltages and

currents ivere recorded at three positions: at substations 4 and
_0 and at the hydro-power station. Seventy-eight effects were
recorded simultaneously with multi-beam cathode-rayloscillographs
and forty by means of electromagnetic oscillographs. The
programme of investigations included: a) overvoltage measurements
on interruption of electrical transmission under conditions of
synchronous operation of the Moscow system and of the hydro-power
station (the disconnection was effected by circuit breakers BBl,
B33 and "'BO; b) similarly but with synchronous operation of
the Noscow system and the power station (interruption was effected
by circuit breaker 13B3); c) overvoltage measurements on dis-
connecting an unloaded section of the line 423 JCm long between
substations nos. 4 and 2 with.circuit breaker BB4;
d) overvoltage measurements on disconnecting an unloaded section
of'line 559 km long between the hydroelectric power'station and
substation no.2 by circuit breaker BB1; e) overvoltage measure-
ments on disconnecting an unloaded section of the line 423 km long
between substations nos. 4 and 2 by circuit breaker BB This
section was disconnected as part of an unloaded line 9h, km long
(breaker BB4 was first opened). In this casp the circuit-breaker

operating conditions were more severe than in tests c and d.
Detailed test results'are tabulated. During the course of fte
programme there were cases of disconnecting short-circuits on the
line, which occurred during several protective spark gap Vreak
downs, and also during inter-phase flashover of line insulator;
during one of the tests. These cases afforded the possibility of
checking the reliability of the circuit breakers in disconnecting
short-circuits and permitted the following new observations-
The overvoltage.wave which causes the short-circuit is reflected
from the point o:V4,the short-circuit with inverted sign and is
then doubled on the substation (or- power 'station) busbars if these
latter operate under 'dead end' conditions. Dangerous over-
voltages then occur on the substation even before disconnection.

additional.operations of the protective spark gaps at the hydro-
electric station when the protective spark gap operated in no.2
substation (tests on disconnecting unloaded section of 423 km by
circuit breaker BB3) and during interphase flashover of line
insulators occurring at the instant of interruption of a line

length of 981 km by circuit breaker BB4. The following conclusions
are drawn from the tests. 1) Tests on circuit breaker
VV,NR-20001-500/2000 were carried out under difficult conditions in
respect of recovery-voltage (UP to 3-85 Uphase with
t = 5 - 10 milliseconds). They showed that the circuit-breaker
extinction chambers operate with complete reliability under all the
required switching conditions (interruption of synchronous and
asynchronous transmission, disconnection of unloaded lines,
disconnection of short-circuits, etc) without special resistors
shunting the extinction chambers. 2) An electric strength of
2.7 U for the circuit breaker disconnector is insufficient for
phase
reliable operation in a-500 kV electrical transmission.system and,
it should be raised to 3-5 Uphase'

ABSTRACT: There are no data in publications on the chlorination of
1 a,e,y,n,.
acetenyldivinyl, whereas that of diviny . . was investi-
gated in detail (Reference 5). In the chlorination process
of divinyl acetylene its di-, tetra-and hexachlorine derivates
form and the formation of each oubsequent. compound from the
preceeding one takes place by addition of c lor in the
con uga
position 1,4, i.e. at the endings of the 5 ier"Renine or
diene. Possibly the reason for this regularity is the symmetri-
cal structure of divin.,~]. acetylene: Acetylenyl divinyldiffers

molecules, so that a different course of chlorination was to

nation velocity of divinylacetylene compared to that of divinyl
acetylene was found. The inves,,tig,,tion of the chlori-
nation reAction of the latter could prove, besides further
syntheses, useful also in technical fields. Different from
divinyl acetylene the chlorination process of acetylenyl divinyl
proceeds till to saturation, i. e. to the octachlorohexane.
According to its structure the octachloride to be expected
would have to have the formula 1t1,2,2,3,4,5,6 octachlorohexane=
CHC1 - Ccl - CHCl - CHCl - CHC1 - CH Cl. This way by the
2 . 2 2
chlorination of ac-!tylenyld.ivinyl the following compounds not
described in publications were aynthetized: 1,6-dichlorohexa-
triene - 1,2,4; 1,2,3,6 - tetrachlorohexadiene -1,4; 1~2,3,4t516-
-hexachlorohexene - 1 and 1,1,2,2,3,4,5,6 - octachlorohexane.
Di - and tetrachlorine derivatives are extremely unstable li-
quids with a strange unpleasent smell; they soon split off
hydrogen chloride and resinify. Octachlorohexane forms scaly

TEXT: This compound was first prepared, in its crystalline form,
bY Coffman and Carothers (Ref.1). During the chlorination of
divinyl acetylene, the authors obtained the above-mentioned
compound which constituted about 90% of the end product (melting
point 590) and also a new substance (melting point 91*) and showed
that one of the compounds represented the trans- and the second the
cis-modification of the substance. Dehydrohalogenation of these
hexachlorohexenes gave the corresponding cis- and trans-2,3,4,5- x
tetrachlorohexatrienes-1,3,5 which can be polymerized. It was
also shown that cis- and trans-tetrachloro-1,3,5-hexatrienes were
formed during the chlorination and bromination of the
corresponding hexachloro- and dibromo-tetrachloro~-2,4-hexadienes.

Incomplete dehydrochlorination of the starting material gives
2,3,4,5,6-pentachloro-1,3-hexadiene and ozonolysis of the latter
compound gave 2,3,4,5-tetrachloro-2-pentanoic acid which has
hitherto not been described in literature. Trans-isomers usually
have a much higher melting point and a lower boiling point than
the cis-isomers. However, in the present investigation, the
melting point of the cis-compound was considerably higher than that
of the trans-compound. This is probably due to the presence of
asymmetri.cal C-atoms with an equal degree of asymmetry which
causes the formation of diastereo-isomers. The monomers
polymerized either spontaneously or in the presence of peroxides
although the cis-tetrachlorohexatriene shows a tend ncy to
dimerization. Various polymerization stabilizersysuch as
phenol-P.-naphthylamine, hydroquinones n-tert.-butyl-pyrocatechol
can be used to inhibit the polymerization reaction. The polymer
of the trans-modification, obtained in an aqueous suspension in the
presence of benzoyl peroxide,is a thermoplastic mass wxth. high

TEXT: Bromination of divinyl acetylene gave two modifications of
hexabromide: the basic modification with melting point of 104 to
1050C representing 80% of the end product which is the t37anS-isomer
of the compound; the second modification had a melting point of 810.
Berizene could be used as solvent instead ofcarbon tetrachloride.
Dehydrobromination of the trans-isomer gave 2,3,4,5-tetrachloro-
1,30-hexatriene and the corresponding crystalline bromine
derivative which could be polymerized. The structure of the
latter was confirmed by ozonolysis. It was proved that the gaseous
and liquid monomers can be polymerized to liquid or solid substances.
The 2,3.o4,5-tetrabromo-l-hexatriene and -3,5-hexatriene monomers
which are solid compounds can be polymerized by dissolving the same
in substances which are solvents for the monomer, but not for the

polymer, e.g. acetone, ethyl ether and alcohols. The tettrabromo-
hexatrienes were chlorinated and brominated; the reaction
mechanisin is discussed. It was not possible to confirm the
structure of Br-derivatives by ozonolysis or oxidation.
Chlorination of the 2,3,4,5-tetrabromo-1,3,5-hexatriene gave
tetrachloro-tetrabromohexene. The rate of polymerization of the
Br derivative is much higher than that of the Cl derivative. The V~
polymer is a powdery product, soluble in benzene dichlorciethane,
chloroform and carbon tetrachloride and insoluble in acetone and
methyl and ethyl alcohols. Polytetrabromohexatrienb shows high
solubility in organic solvents and it can therefore be st:ipposed that
the pQ1zmtr4zationjproceeds ac.cording to the 1-6 mechanism. The
chemical composition of the polymer was defined by bromine analysis.
Details of the synthesis of the various compounds and analytical
data are given. There are 4 references: 1 Soviet, 2 En~,,Jish and

TEMP: Alkylated aromatic monomers or low-molecular
polymers are formed during the condensation of alkyl haloids and
aromatic compounds; reaction conditions such as the ratio of the
starting compounds, temperature, etc. influence the character of
the end-products. G. S. Kolesnikov and V. V. Korshak carried
out systematic investigations on this reaction (Refs. 3-8~ 14$

kinetics, the effect of solvents, etc. The present investigat-
ions proved that 1,2,5,6-tetraphenyl-3,4-dichloro-3-hexene was
formed as one,of the basic condensation products, under suitable
reaction conditions. The yields depended on the ratio of the

TEXT: 1,3-butadiene is produced in large quantities as by-product
during the dimerization of acetylene in the~production of
chloroprene rubber. The authors-carried out tests on the
chlorination of hexachloro-3-hexene and found that earlier
statements on its stability were not quite-accurate as
1,112,2,3,4,5,5,6,6-decachloro-3-hexene was formed-during the
photochlorination of its cis- and trans-mod'ification; during
extensive photochlorination hexachloroathane is formed, The-
authors suggest the following meebanism for the chlorination
reaction: at the beginning of the experiment, the double bond in
both modifications of hexachloro-3-hexeneischlorinated-and-

TITLE: Overvoltage of the Cathodic Reduction of Oxygen and the Activa-

PERIODICALt Zhurnal fizicheskoy.khimii, 19599 Vol 33, Nr 7,
pp 1625 - 1631 (USSR)
ABSTRAM The process of the cathodic reduction of oxygen (1) proceeds
in two stages on various electrodes in alkaline and acid medium
(Refs 1,8,9). Since investigations have hitherto been carried
out at room temperature, the author made here experiments in
acid (1-0158 n H 2so 4) and alkaline (I n NOR) medium at 0, 20,
40 and 60 0C-by means of mercury, platinum, gold, and silver
electrodes. An apparatus (Fig 1) was used and the electrode
potential was measured by means of a highly resistive direct-
current potentiometer PPT-1 according to a compensation scheme.
The Hg electrode had a surfnce of 5 cm2, the other electrodes
one of 2.5 OM2. The resultant curves of the dependence of tho
overvoltage W upon the logarithm of density current (1g i)
show (for bot media) two segmenta. Both segments may be de-

values of the constants a (Table 1) and b. The first segment
of the curves q, Ig i is assumed to correspond to the reduc-
tion of (I) to hydrogen peroxideq and the second segment, to
the formation of water. The values of b indicate that the first
segment in alkaline medium correspondu to a concentraTion
polarization. Otherwise apparently electrochemical polarization
takes place (Table 2). According to the results of measure-
ment, the author calculated by an equation (-!6) the values of
the activation energy (A) of cathodic reduction of I (Table 3)
as well as of the corresponding pre-exponential factor B (equa-
tions (17), (18), Table 4). A ancl D are only little dependerit.

fessor B. N. Kabanov and Professor M. I. Temkin for their
assistance~ There are 3 figures, 4 tables, and 16 references,
