ZW32-12 series outdoor AC high voltage vacuum circuit breaker (hereinafter referred to as ""); Circuit breaker "is a three-phase AC 50Hz outdoor high-voltage switchgear mainly used for 10kV outdoor distribution systems in rural and urban networks, as a means of breaking and closing load currents, overload currents, and short-circuit currents; It can also be used in other similar fields
Main features and applications
1. It has the characteristics of stable and reliable breaking performance, no combustion and explosion hazards, maintenance free, small size, light weight, and long service life. Good sealing performance helps to improve moisture and condensation resistance, especially suitable for use in cold or humid areas.
2. The three-phase pillar and current transformer adopt imported outdoor epoxy resin solid insulation, which has the characteristics of high and low temperature resistance, UV resistance, and aging resistance.
3. The operating mechanism adopts a miniaturized spring operating mechanism, with low power of the energy storage motor and low energy consumption for opening and closing.
4、It can be matched with intelligent controllers to achieve distribution automation, and can be combined with coincidence controllers to form automatic reclosers and sectionalizers.
5、Circuit breakers can be equipped with two-phase or three-phase current transformers for overcurrent or short-circuit protection, and can also provide current acquisition signals to intelligent controllers
6. The circuit breaker can be equipped with a three-phase interlocking isolation switch and has an anti misoperation interlocking device with the circuit breaker body.
