Product Description
High voltage vacuum Circuit Breaker
1. Outline
The ZW7-40.5 outdoors high vacuum circuit breaker uses in to exchange 50Hz, the 40.5kV three-phase electrical power system, the achievement divides, of of gathers using of the load current, the excess current and the short-circuit current.
This circuit breaker conforms to national standard GB1984-89 "A. C. High voltage Circuit breaker" and international electrician committee standard IEC56 "High-pressured Exchange Circuit breaker" request.
Circuit breaker main characteristic
A. Uses the vacuum extinguishing of arc, opens breaks the ability strongly, the electricity life is long, mechanical life 10, 000;
B. Structure simple, exempts the maintenance, the overhaul period is not long;
C. Insulating ability good, the anti- contamination ability is strong;
D. May match the spring or the electromagnetism holds the drive mechanism, the machine capability is reliable, but frequently operates; Does not have the fire and the detonation hidden danger;
E. The internal installation current transformer measuring accuracy reaches 0.2 level, may realize the three-phase differential motion protection;
F. Congeals the dew controller, can maintain the circuit breaker under the certain temperature humidity the reliable movement.
2 Circuit breaker exploitation conditions
A. Surrounding air temperature upper limit +40 ° C lower limits general areas -30 ° C, high and cold area -40 ° C;
B. Elevation does not surpass 1000m;
C. Wind pressure does not surpass 700Pa (to be equal to wind speed 34m/s);
D. Earthquake intensity does not surpass 8;
E. Air contamination degree III level
4 The contour and installs the size
Zhejiang Xiya Electric Equipment Co., Ltd. Was founded in 1995, invest about more than RMB 10 million, one of the high-tech enterprise of production, sales, research and development. The company covers a land area of 5 acres. We are specialized in manufacturing dropout fuse cutout, zinc oxide arrester, isolating switch, lightning protection insulator, composite insulator, bushing and surge protector and complete sets of products. Our company has been elected to Two-Net reconstructing enterprise by Nation Economy & Trade Committee.
