The zw32-12 vacuum circuit breaker is equipped with a spring energy storage operating mechanism, which can be operated manually, electrically and remotely. An isolation switch can be installed on the side of the circuit breaker to form a combination of outdoor high-voltage vacuum circuit breaker and outdoor high-voltage isolating switch, which increases visible isolation fracture and has reliable interlocking operation. According to the requirements of the user, it can cooperate with the corresponding controller to form the ac high-voltage vacuum automatic collator and automatic sectioner.it is the ideal equipment to realize the automation of distribution network. The high voltage transformer is external and built in. Zw32a-12 is a combination of zw32-12 circuit breaker and disconnecting knife. It is called a combined circuit breaker and can be used as a section switch.
Zw32-12 / electronic PT outdoor high-voltage vacuum circuit breaker has all the functions of the basic type circuit breaker. This type circuit breaker is equipped with electronic PT. The power is taken from CT to recharge the battery.
It has the functions of closed current control, overcurrent protection and three-section combined protection of short circuit speed break. The protection parameters can be set continuously by the user.
It can be controlled by wire or wireless remote control under lever.
1) according to the user's needs, the external insulation of the current transformer is 50/5, 100/5, 200/5, 400/5, 630/5
2) the built-in multi-tap current transformer can be used for overcurrent protection
3) double winding current transformer can be used for protection and measurement
4) if the voltage transformer, automatic coincidence controller and automatic section controller are installed, the power distribution protection automation and the "four remote" (telemetry, teleconference, telecontrol and telecontrol) function are installed with compound controller (to eliminate inrush current).
5) isolation switch can be added
