Isolator RV, RVO, EEO, RVFS, RLO

Isolator RV, RVO, EEO, RVFS, RLO designed for switching energized sites of an electric chain in the absence of load current and to change the schema of the connection, to ensure safe production works on the disconnected site, to enable and disable charging currents of air and cable lines, idle current of transformers and currents small loads.

Disconnectors are used in areas where vibrations the temperature and humidity of air insignificantly differ from fluctuations in open air and there is relatively free access outside air, for example in tents, bodies, trailers, metal housing without thermal insulation and casing complete devices or shed to to avoid direct solar radiation and atmospheric precipitation on the products. The room in which are mounted the circuit breakers and drives must to be closed, explosion and fire-proof, not containing corrosive gases and vapor in concentration that destroy insulation and protective coatings. Drive -lever mechanism to manually enable and disable disconnectors.

The disconnectors are manufactured in versions UHL3 and designed to operate under the following nominal conditions:

- height above sea level up to 1000 m;

- ambient temperature air - from minus 40 to +40°C;

- upper value relative humidity - 100% at the temperature of +25°C (moisture condensation).

Decoding a symbol of the disconnector:

R - disconnector;

In indoor installation;

F - figure(through insulators);

S - availability of earthing switches;

I - with earthing switch side separable contacts;

II - earthing side hinge contacts;

III - earthing switch with two of the parties;

10 - nominal voltage, kV;

630 - nominal current, a;

II - through insulators with side hinge pins (for RWPS);

III - through insulators with side separable contacts (for RWPS);

IV - bushings c both sides (for RWPS);

- Climate version according to GOST 15150-69;

3 - placement category according to GOST 15150-69.
