summary
The vacuum fault on the ZW32 outdoor column(below) is an outdoor high voltage distribution device with rated voltage of 12KV and three-phase AC 50Hz. It is mainly used for opening and closing load current, overload current and short-circuit current in power system. It is suitable for protection and control in substation and power distribution system of industrial and mining enterprises. It is also suitable for urban and rural power grid construction and frequent operation.
The ZW32 vacuum circuit breaker is equipped with a spring energy storage operation mechanism that can be operated manually, electrically and remotely. The isolation switch can be installed on the side of the breaker to form an outdoor high voltage vacuum circuit breaker and an outdoor high voltage isolation switch combination appliance, which adds a visible isolation fracture and has a reliable interlocking operation. According to the requirements of the user, it can be combined with the corresponding controllers to form an AC high voltage vacuum regenerator, automatic segmenting device, and self-operated power supply. It is an ideal equipment for realizing distribution network automation. The high voltage voltage transformer structure is used to externally install. ZW32-12G / 1250-20. The ZW32-12 series column outdoor high voltage vacuum circuit breaker is an outdoor high voltage switch device with three-phase AC 50Hz and rated voltage 12kv. Suitable for opening, closing and closing the load current, overload current and short-circuit current of the power distribution system in the city or rural area. The circuit breaker is a new miniaturized design, a fully enclosed structure, and a unique arc extinguishing chamber packaging technology. The sealing performance is good, moisture proof, and condensation proof. It is suitable for high temperature and humidity areas. The ZW 32-12G circuit breaker isolation switch combination is composed of two parts: the ZW 32 circuit breaker isolation switch.
