ZN63[VS1]~24KV Series Indoor Solid Sealed Vacuum Circuit Breaker

ZN63-24 series vacuum circuit breaker is a new type of circuit breaker independently developed by Hearkou Electric Power. The use of solid seal pole structure, can also be used insulation simple structure. 2N63-24 series Naoyasuo road gold is a three-intersecting source 60-60H2 set pressure of 24KV indoor and closed installation pipe, as a power grid equipment, power equipment and control unit. The primary part of the solid column circuit breaker adopts the APG process to protect the vacuum interrupter and other main circuits from the impact of push, dust and condensation, which is suitable for frequent operations requiring rated working current, or places where the short-circuit current is broken multiple times, and is also used in places with harsh environmental conditions. ZN63-24 real circuit breaker through various forms of tests, according to the latest national standard M2 level 20000 machine life type test, according to E2 level 274 short circuit current to complete the circuit breaker electrical life type test, can ensure safe operation under normal conditions of use. Factory inspection: mechanism characteristic test, main circuit power frequency voltage test, control circuit insulation test, main circuit resistance test, interlock operation test, mechanical and electrical operation test.
