Product Description
The VS1(ZN63)-12 series solid-insulated indoor high-voltage vacuum circuit breaker adopts a solid insulation structure, utilizing advanced epoxy resin encapsulation technology. For the first time, it integrates the main conductive circuit of the vacuum interrupter and insulation supports into a single solid-sealed pole unit, fundamentally resolving environmental endurance issues in vacuum circuit breakers and significantly broadening their application range.
The integrated solid-sealed pole unit incorporates patented self-convection ventilation technology, ingeniously addressing the heat dissipation challenges inherent in solid insulation structures.
The VS1(ZN63)-12 series is China's first vacuum circuit breaker to achieve a maintenance-free design:
The long-life vacuum interrupter and epoxy resin encapsulation technology ensure the solid-sealed pole unit requires no maintenance.
The high-reliability permanent magnet operating mechanism guarantees maintenance-free mechanical operation.
The electronic control system eliminates traditional auxiliary switches, replacing them with photoelectric proximity sensors, while an all-electronic power supply and intelligent control unit ensure maintenance-free electronic operation.
