◆ Product overview

ZW32-12 series outdoor high-voltage vacuum circuit breaker (hereinafter referred to as "circuit breaker") is used in three-phase power system with AC 50Hz and rated voltage of 12kV, as the short-circuit current of load opening and closing current and overload ammeter. It shall comply with the national standard GB1984 High Voltage AC Circuit Breaker, the professional standard JB3855 Outdoor AC High Voltage Vacuum Circuit Breaker of 3.6~40.5kV and relevant IEC standards. The circuit breaker can be configured with a reclosing controller to identify current characteristics and realize multiple automatic reclosing or permanent fault isolation; The self provided PT is used as the power supply to become an intelligent circuit breaker with voltage and current signal output and can be controlled; The power supply is provided by the electronic PT and the three section composite protection of overcurrent delay, inrush current delay and short circuit quick break can be completed.
ZW32-12Y outdoor permanent magnet high-voltage vacuum circuit breaker combines the world's new permanent magnet mechanism, epoxy resin monolithic casting solid insulation technology and other advanced technologies, and uses vacuum breaking technology, which has the characteristics of long electrical life, reliable breaking and long-term complete maintenance free. The external insulation is made of imported outdoor special epoxy resin, which has the advantages of ultraviolet resistance, flashover prevention and pollution resistance. This product is completely oil-free, SF6 free, maintenance free, and does not pollute the environment. Advanced permanent magnet mechanism is adopted, with stable and reliable mechanical performance; It is also equipped with a manual opening and closing mechanism, which can be manually opened and closed on site when necessary.
