N63A VS1 12kv Indoor AC Vacuum Circuit Breaker interruptor
Type ZN63A (VS1) indoor ac high voltage vacuum circuit breaker( interruptor ) hereinafter referred to as circuit breaker ( interruptor ) is indoor three-phase ac rated voltage switch equipment, available for industrial and mining enterprises, power plants and transformer substations for electrical facilities, control and protection, and is suitable for frequent operation. Circuit breaker ( interruptor ) conforms to the ac high voltage circuit breaker ( interruptor ) , 855-1996 < 3.6-3.6 kV indoor ac high voltage vacuum circuit breaker ( interruptor ) ", DL403-91, the 10 to 35 kV indoor ac high voltage circuit breaker order technical conditions "standard requirements, and in accordance with IEC56. The requirements of the relevant publications (87). Circuit breaker ( interruptor ) operating mechanism and circuit breaker ontology unibody design, as well as fixed installation unit, also can with special propulsion mechanism, form a handcart used unit.
Sealing type ceramic or glass in the circuit breaker ( interruptor ) with vacuum arcing chamber adopts copper and chrome contactor material, cup shape and longitudinal magnetic field contactor structure, its contact electrical wear rate is small, long service life, high contact pressure levels, dielectric insulation strength stability, back-arc recovery speed, intercepting level at the end of a period of strong ability.
Circuit breaker ( interruptor ) operating mechanism for its overall structure and layout of the arcing chamber before and after, in the form of dominant part electric circuit for the three-phase structure on floor, vacuum arcing chamber longitudinal cylinder is installed in a tubular insulation, insulation tube by using the APG epoxy resin craft casting and become, and its special anti creepage. This kind of structure design is greatly reduce dust on the surface of the arc extinguish chamber, accumulation, not only can prevent damage of vacuum arcing chamber by external factors, but also can ensure even under hot and humid and severe pollution environment effect on voltage present a high impedance state. The main loop of the circuit breaker in the closing position current path: On line 28 by fixed on the arcing chamber of the stent on 27 to the vacuum arcing chamber static contact, the contact and connection of conductive clip, soft connection, 30, to support the line 32. An insulating rod 34 and 33 internal disc springs pass circuit breaker ( interruptor ) connecting rod system to complete the operation of the circuit breaker movement and keep contact contact.
