HV outdoor vacuum circuit breaker

ZW32-12 outdoor high-voltage vacuum circuit breaker is an outdoor high-voltage distribution equipment with rated voltage of 12kV and three-phase AC 50Hz. It is mainly used for breaking and closing load current, overload current and short circuit current in power system. Switch structure features: 1. The circuit breaker adopts three-phase pillar structure, with stable and reliable breaking performance, no combustion and explosion hazard, maintenance-free, small size, light weight and long service life. 2. The circuit breaker adopts a fully enclosed structure with good sealing performance, which helps to improve the moisture-proof and anti-condensation performance, and is especially suitable for use in cold or humid areas. 3. Three-phase pole and current transformer shall adopt imported outdoor epoxy resin solid insulation, or indoor epoxy resin wrapped with silicone rubber solid insulation; It has high and low temperature resistance, UV resistance, aging resistance and other characteristics. 4. The operating mechanism adopts a miniaturized spring operating mechanism, the power of the energy storage motor is small, and the energy consumption of opening and closing is low; The mechanism transmission adopts the real transmission mode, with small number of parts and high reliability. The operating mechanism is placed in a sealed mechanism box, which solves the problem of operating mechanism corrosion and improves the reliability of the mechanism. 5. The opening and closing operation of the circuit breaker can adopt manual or electric operation and remote control operation. It can be matched with intelligent controller to realize distribution automation, and can also be combined with reclosing controller to form automatic recloser and sectionalizer. 6. The circuit breaker can be equipped with two-phase or three-phase current transformers for overcurrent or short circuit protection, and can also provide current acquisition signals for intelligent controllers; Current transformer for metering can be installed according to user requirements. 7. The circuit breaker can be equipped with a three-phase linkage disconnector, which has obvious visible fracture under the opening state of the disconnector, and has an anti-error interlocking device with the circuit breaker body. The circuit breaker can only be operated when the disconnector is fully closed or fully opened. The lightning arrester post insulator can be connected for convenient maintenance.
