High voltage vacuum circuit breaker / Handcart

ZN85B - 40.5 type indoor vacuum circuit breaker is quzhou electric electric co., LTD in ZN85 av3 (3) based on the characteristics of VS1 spring operating mechanism, combined with domestic practical design and production operation, the product is suitable for use in 40.5 KV rated voltage, three-phase ac 50 hz indoor high voltage equipment, available for industrial and mining enterprises, power plants and transformer substations as control and protection of electrical equipment, and is suitable for frequent operation.

Circuit breaker arcing chamber and operating mechanism before and after arrangement of structure, effectively reduced the depth of the circuit breaker es with organic composite insulation materials, based on ZN85 40.5 av3 (3) increase the arm insulation, design more compact, further reduced the volume of circuit breaker; The leading electric circuit is connected directly with the vacuum arc extinguishing chamber, making the electrical connection more reliable.

Operating mechanism of the same form with VS1 spring operating mechanism, and its operating mechanism under vacuum arcing chamber, inside the case before its operating performance and the arcing chamber open and close more consistent performance, reduced unnecessary intermediate links and improves the performance of the circuit breaker is more reliable; The improved screw propulsion mechanism is adopted, which is efficient, stable and self-locking.
