TITLE: A Universal Welding Rectifier With a Wide Range of
Control of Voltage and Current
PERIODICAL: Vestnik elektropronyahlennosti, 1960, No.10, PP.36-41
TEXT: The main technical requirements applicable to supply
sources for automatic welding in inert gas are formulated: the
volt-ampere characteristics must be flat in the working range;
-smooth control of output voltage under load must be possible;
the output voltage must be automatically stabilized against load
variations and input voltage variations; the no-load voltage
must be high enough to strike an are reliably and the dynamic
.11aracteristics must be satisfactory. It is also generally
,Icsirable that the supply should be able to provide a family of
drooping characteristics for manual arc welding. Several methods
of obtaining flat volt-ampere characteristics are considered and

dismissed in turn because of various defects, A universal supply
having either level or drooping volt-ampere characteristics can be
obtained from a static supply source consisting of a step-down
three-phase transformer, a variable Inductance and a rectifier unit.
The inductance is in series with the high- or low-voltage side of
the transformer and the load is supplied through the rectifier,
This gives a family of naturally drooping external characteristics,
each curve Sorresponding to a certain value of inductance, Flat
volt-ampere characteristics are obtained by automatically altering
the inductance of the power circuit with the load, The principles
underlying this idea are explained, The most suitable form of
variable inductance in a saturating choke which can be used to
provide flat external characteristics by alteration in the
inductance of the choke. A schematic circuit diagram of the
equipment in given and explained. It it is necessary to improve
the dynamic characteristics of the equipment, a power magnetic
amplifier of suitable design may be used as a variable inductance.

A Universal Welding Rectifier With a Wide Range of Control of
Voltage and Current
There is a circuit diagram of a 300 A experimental equipment with
this feature. By throwing a switch,suitable flat characteristics
are obtained. The natural drooping external characteristics are
plotted. The technical and economic characteristics of welding
rectifiers built according to this circuit depend"upon the desired
range of control of stabilized voltage and on the limits of
current control. If it is necessary to control voltage and
current over a wide range it is best to have two ranges of control
by altering the no-load voltage of the equipment. Technical data
of prototype equipment are given and, for example, the rated
voltage of 30 V any be altered from 17 to 34 V and the welding
current from 50 to 320 A. The prototype welding set was of good
performance with both automatic and annual welding. The set in a
little larger and less efficient than previous sets but this is
compensated by its universality. The weight could be appreciably
reduced if the control range were not so wide. There are

TITLE: Welding rectifier with elastive and falling characteristics
PERIODICAL: Avtomaticheskaya svarkap no. 61 1961p 63-72
TEXT: VNIIESO has developed a new BC~ (VSU) type welding rectifier suit-
able for automatic gas-shielded as well as for manual are velding. The first
VSU-300 and VSU-500 units have been completed, and production is planned to
start during 1961. The circuit diagram (Pig. 1) and phoiograph (Fig. 10)
(with renoved casing) of the VSU-300 are given, and its operation is describ-
qd. The VSU represents an improvement, for the existing Soviet rectifiers do
hot adjust the work voltage smoothly under lo4d and work with other than
elastive characteristics. The VSU includes special saturation chokes. Its
universal, i.e. both elastive and steep falling characteristics are obtained
from a feed source consisting of a step-down transformer, saturation choke
and semiconductor rectifior unit. The output voltage of the rectifier re-

ABSPRACT: This Author Certificate presents a universal welding rectifier. The
rectifior includes a power transformer, a regulation unit, and a saturation choke
coil with control windings. The operating windings of the choke coil are joined in
parallel and are connected in series with the rectifiers of the semiconductor power
rectifier. The design simplifies the production of steep-dipping and flat-dipping
external volt-ampere characteristics. One of the control windings of the saturation
choke coil is connected to an unregulated voltage and serves as the bias winding
in association with the flat-dipping external characteristics and as the preliminary
magnetization winding in association with the steep-dipping characteristics. The

other control winding is connected to a regulated voltage, and provides the control
in association with the flat-dipping external characteristics. The other control
windi ng in association with the steep-dipping characteristics serves for producing
the welding current feedback.

PERIODICAL: Teploene rget ika , 1959, Nr 3,, pp 19-25 (USSR)
ABSTRACT: It is timely to consider the most efficient way of using
gas as a power-station fuel. Stations may operate with
gas turbines, with steam turbines or with a combination
of the two. So far a procedure for comparing these
types of power station has not been formulated.
Fundamentally, the combined station consists of a steam
boiler and gas-t-urbine combustion chamber -as a single
unit: a high-pressure steam generator operates on the
gas side under a pressure set up by the compressors of
the gas-turbine set. With this method of operation, the
heatin- surfaces are small and much less than the normal
0
amount of metal is required. In the steam grenerator the
amount may be only 0.55 - 0.70 kg/kg steam, i.e. a quarter
Card 1/5 of that in an ordinary boiler. In comparing a gas-fired

SOV/96-59-3-4/21
Steam-Gas Condensing Power Stations and Their Comparative Thermal
Efficiencies
steam station*and a combined station (without inter-
mediali-e cooling of the compressors in the gas-turbine
group), it is assumed that with equal excess air factors
and equal initial steam conditions an equal quantity of
fuel is consumd in both stations. Then if the outlet
gas temperatures are eqaal, the associated losses are
also equal. A ccmparison is then made between the thermal
efficiencies of a gas-fired steam station, a gas--turbine
installation and a combined steam-gas installation, the
schematic diagram of which is given in Fig.l. This
installation consists of a gas-turbine group, a condensing-
type steam turbine, a hig~h-pressure steam generator and
regenerators. The gas and air are compressed in the
compressors of the gas-turbine stage and after heating in
the regenerators are delivered to the steam generator,
which serves also as the combustion chamber of the gas
turbine. The combustion products are used successively
as heat-transfer medium for steam raising and as working
Card 2/5 substance for the gas-turbine installation. The steam

Ef f icie ncie s
generator reduces the temperature of the combustion
product to a value suitable for the gas turbine. After
the combustion products have expanded in the ga8 turbine
and passed through the regenerators they are discharged
to atmosphere. The theTual circuit of the steam stage
is normal. Comparative thermal efficiencies of the
three types of station are then calculated. The ratid
between the outputs of the gas turbine and the steam
turbine affects the thermal efficiency in the manner
plotted in Fig.2. A general comparison of the thermal
efficiencies of the three types of station for different
conditions is seen in Tables 1 and 2. Table 2 compares
a combined and a gas-turbine station for different
ratios of heat. consumption in the steam- and gas-turbi-ne-s.
The procedure described above was used to make a general
evaluation of the thermal efficiency of a combined station,
The influence of individual parameters of the cycle on the
efficiency were considered. The particular factors

gas stage. Calculated values of efficiency for
combined steam-gas stations are plotted in Figures 6 and
?. The calculations relate to gas obtained by underground
gasification of coal. The conditions assumed in the
calculation are stated. The graphs may be used to
compare the efficiencies of steam, gas and combined
stations for different steam conditions and gas-turbine
operating conditions. The curves in Fig.8 shcw the
range of efficiency of combined and gas-turbine stations.
It is concluded that in the combined station, the grE!atest
fuel economy results from the use of medium, and high
initial steam conditions; also that the thermal
efficiensy of the combined steam-gas systems is then
higher than that of a gas-fired steam station. The range
in which the combined station is most efficient is
somewhat extended when heat is delivered to the gas
stage in two steps, Combined installations give hioier
fuel economy than gas turbines having low inlet
Card 4/5 temperatures. The output of combined stations is

governed by the unit output of the steam stage and their
use will be most effective in power stations of small
and medium output. There are 8 figures, 2 tables and,
