РГ(Н)-СВЭЛ-110 high voltage circuit-breaker

Description

Circuit-breakers and drives РГ(Н)-СВЭЛ-110 are made with climatic class NF, 1 category of disposition as per GOST 15150, they are intended for outdoor installation with altitude 1000 m above sea level in districts with temperate and cold climate under the following conditions:

• non-explosive environment, free of dust in concentrations that reduce the product parameters within inadmissible limits. Environmental pollution conditions shall comply with Type II atmosphere according to GOST 15150;
• upper operation ambient temperature 40°C;
• lower operation ambient temperature -60°C;
• circuit-breaker ensures safe operation in ice-covered conditions with ice crust thickness up to 20 mm and wind speed up to 15 m/s, and in the absence of ice up to 40 m/s;
• seismic intensity of installation area on the MSK-64 scale - 9 points.

Circuit-breakers and drives РГ(Н)-СВЭЛ-110:

• operation under conditions of surfaces contamination II*, III or IV degree as per GOST 9920;
• meet the requirements of GOST R 52726 and 0ЭТ.065.003 Specification;
• in terms of safety meet the requirements of GOST 1516.3; GOST 12.2.007.3; GOST R 52726; 2.2.4.1191 and СН 2.2.4/2.1.8.562 of Sanitary Regulations and Standards;
• can be manufactured for special operation conditions according to customer`s requirements.

Assembly

Circuit-breaker РГ(Н)-110 includes:

1. circuit-breaker in three-pole or single-pole version (and its units);
2. drives;
3. supporting structures or carrier for drives fastening;
4. spare parts kit (upon request).

The following set of operating documentation is accompanied the circuit-breaker:

• passport 1 pc;
• operation manual 1 pc;
• installation drawing 1 set.

РГ(Н)-СВЭЛ-110 circuit-breakers design features:

Assembly is designed for vertical and horizontal installation with rigid busbars. Maximum extension height up to 1.5m, maximum length of bus link up to 8m.

Reliable atmospheric effects protection. Mating contacts are protected with enclosure that prevent precipitation and ice formation.

Main and earthing contacts construction ensures reliability of contact joints by means of simplicity.

Silver cover of the main contacts and nickel cover of the earthing contacts guarantee high durability and stability of electric contact.

Higher sufficiency due to the increased number of contact areas up to 8.

Higher sufficiency due to the increased number of contact areas up to 8.

Increased reliability of the contact connection at short-circuit currents due to the fact that the dynamic contact pressure at Iw =100kA is increased to 2480N.

Optimal transport conditions with regard to expenses and safety. 1 piece of cargo, in some cases 2.

Minimum amount of mounting work during installation because of high level of pre-fabrication.

Circuit-breaker assures reliable electric contact during the whole service life and increases assembling convenience by means of springs absence in lamels.

Elimination of project errors, due to the adaptable design of circuit-breaker, allows to install an earthing blade on the side of any of the columns, reduces the volume of spare parts and accessories.

All components are manufactured in the Russian Federation.
