about CoMPanY

ABS Holdings enterprises more than 50 years operate in the electrical markets of Europe, Asia, Africa and the CIS countries. They manufacture a wide range of LV and HV equipment success-fully used in power utilities, metal, building, mining, gas and oil, railroad industries and municipal transport facilities.

Based on multiyear experience and production possibili-ties the Holdings is successfully implementing turn-key solutions and executing general contractor functions.

Samples of products are subject to testing and certification. Products have high service reliability.

Current distributor and busbar design and production is local-ized in “VNIIR” JCS. The enterprise includes R&D division equipped with the most up-to-date design facilities. High quality of current distributors and busbars is attained by the use of high-perform-ance equipment manufactured by russian and west companies, e.g. «SCODA», «WAYTRAIN, SAHINLER», «IPM2», «PRINCING», «SELKO», «KOIKE ARONSON INC.», «FIRO», «Donpressmash» etc. This equipment allows the manufacturer to roll-form screens of 360-1500mm diameter with length up to 3000mm and stiffen-ing rings to reinforce rigidity of the structure. Automated welding stations allow to make unattended linear and girth welded seams.

Isolator point tightness is achieved due to special rubber gaskets with 10÷15 % compression set, providing functionality of assemblies up to 20 years. Screens and current distributor buses are painted by powder paints providing reliable protection from weather impacts and high me-chanical resistance of the coat.

Up-to-date processing equipment, availability of skilled designers and employees provide manufacturing of high grade multipurpose cur-rent distributors (including customer-tailored).

Depending on requirements specification current distributors and

busbars can be packaged with different electric equipment: - ТШ, ТШВ, ТШЛ, GSR, IGWG doughnut current transformers; - ЗНОЛ, ЗНОЛП, UGE voltage transformers; - РВЭ, РВРД, РВМ, РВС, РВО, Siemens surge arresters; - ОПН, Siemens voltage suppressors; - triple pole earthing switches; - РВП3, РВР3, РРЧ3, Р3Ч etc. disconnectors; - ИП etc. Wall-tube insulators; - switchgear bays; - ПСН panels or КТПСН-0.5 cabinets.

1.4. Features of current distributor composition

This type of current distributors are mounted in power utilities and substations providing great power distribution. The distribu-tors have long-time serviceability and meet the highest reliability requirements.

Enclosed phase-screened current distributor structure fea-tures:

- eliminate possibility of phase-to-phase short-circuiting due to foreign objects and staff access to current-carrying parts;

- current distributor shield-screens and busbars have linear di-lation compensators for temperature changes compensation;

- current distributors are all-welded except for turbo-generator, transformer and switch tapping;

- current distributor is an electrodynamically stable device;- external magnetic field of the current distributor is compen-

sated. The compensation is attained by connecting shield-screens with jumpers and grounding corresponding route sections;

- detachable contact joints Al/Cu are manufactured of highly reliable transient contacts;

- current distributors are dustproof;- support isolators are proof to dew and frost precipitation. In case

of necessity the isolators can be easily changed without screen disas-sembling;

- distributor inner space is protected from capacitive discharges (sparking) due to special rod contacts.

- current distributor construction provides possibility to remove hydrogen leakages from generator terminals non-tightness points;

- shield-screens are fastened to transverse beams by detachable isolated clams avoiding possibility of induced currents circulation over structural units;

- beams are welded to the structural units;- insulation resistance measurement in screen/transverse beam at-

tachment point is provided without structure demounting;- current distributor screening contributes greatly to reduction of

adjacent metal and concrete structures;- shield-screen-generator and transformer tapping points elimi-

nate possibility of induced currents.

1.5. Current distributor structure

1.5.1 6, 10, 20kV ТЭНЕ current distributors (Figure 1.1).ТЭНЕ family current distributors are manufactured in phase-

screened version. Each phase consists of current-carrying bus 1 of corresponding shape, shield-screen 2 and isolator 3. The bus is fixed to caps bolted to the shield-screens. Max insulator spacing is 3m

reQuireMents to Current distributor and busbar design ParaMeters

Factory provides manufacturing of current distributors indicated in this paper. The factory is capable to produce current distributors and busbars upon customer requirements.

For current distributor route sections where it is not possible to use standard components the factory is capable to design customer-tailored distributors.

The design parameters should include:- route drawing (in disnefied form). The drawing should indicate

elevations and references to construction lines, rectilinear and vertical route section sizes; angular deflections, all necessary cross-sections and other parameters determining current distributor in space;

- layout of sections with integrated equipment;- list of required electric equipment and instruments included in

the scope of supply including types, quantity and manufacturer;- electric equipment parameters to be tapped to the current dis-

tributor (generator, transformer, circuit breakers, switchgears) etc. not included in the scope of supply.

It is necessary to indicate manufacturer of the equipment to be tapped to the current distributor or provide mounting drawings..

Possible differences between description of current distributor structure and actual version indicate constant improvement of the structure, not affecting tapping parameters, performance, reliability and security.

This information can be provided in drawings or drafts on the design parameter drawings of the route.

The design parameter should be approved by the manufacturer of the current distributors.
