Basic Info.
Product Description
General:
ZW30-40.5/2000-31.5 outdoor HV vacuum circuit breaker (hereinafter referred to as ZW30-40.5) can be used
in the power system with rated voltage 40.5KV, rated current 2000A and three – phase AC 50HZ to protect the
equipment in the industrial and mineral enterprises, power plants and substations, which can be used as a
connecting circuit breaker in the workplaces of frequent operation.
This product complies with the standards of the GB1984-89 AC HV Circuit Breaker, IEC56 HV AC Circuit
Breaker and JB3385-1996 3.6-40.5KV Indoor AC HV Vacuum Circuit Breakers.
Features:
A, This product is for outdoor high voltage vacuum circuit breaker, the overall structure of the ceramic column,
a vacuum interrupter in the porcelain, the circuit breaker under the outlet end of the use of the slider-type
contact, the product has a smaller loop resistance and good oriented, the next set of ceramic pillar, to ensure
live parts of the insulation, ceramic kit has absolutely bar, mounted on a common three-phase bottom box on
the upper and lower porcelain comprising a charge 0.02Mpa (20 c) the provisions of gas.
B, the product with 1 to 6 can be independent of the current transformers, transformers can be installed into the
circuit breaker or the outlet end of the line side, or both ends installed. Independent of the current transformer
under its accuracy at any level can meet user requirements, and can be done once or twice without disturbing
each other.
C, with a special trip the circuit breaker signs device that can be read at any time convenient to the vacuum
interrupter trip and overtravel.
D, the circuit breaker oil with excellent cushioning buffer and sub-gate stopper.
E, the circuit breaker is equipped with CT17-IVB-type spring operating mechanism.
