一.ZW32-40.5M outdoor high voltage vacuum circuit breaker

1.1 main use

ZW32-40.5(ZW32-40.5M/ZW32-35M) series outdoor high voltage vacuum circuit breaker (hereinafter referred to as "circuit breaker") is used for AC three-phase power system with 50HZ rated voltage of 35KV as the sub-combination, load current, overload For current and short-circuit current, the circuit breaker can be configured with a coincidence controller to recognize the current characteristics and realize multiple automatic reclosing. The self-supplied PT is used as the power source to become a smart circuit breaker with voltage and current signal output and control, and is controlled by electronic PT. Provides power supply and can complete over-current delay, inrush current delay, short-circuit and quick-break three-stage composite protection.

1.2 Features

ZW32-40.5 (ZW32-40.5M/ZW32-35M) high-voltage vacuum circuit breaker can be equipped with a spring operating mechanism, which has basic functions such as breaking and closing load current, overload current and short-circuit current.

ZW32-40.5 (ZW32-40.5M/ZW32-35M) circuit breakers can be equipped with lightning arresters. The arresters can be installed on either side of the incoming and outgoing lines according to user requirements.

The ZW32-40.5 (ZW32-40.5M/ZW32-35M) circuit breaker can be equipped with an inrush current controller, which has the function of escaping flow and over-current breaking. The circuit breaker can be equipped with 2-3 measuring or measuring transformers. The recloser controller constitutes a recloser type intelligent circuit breaker. The basic type and coincidence controller are suitable for the occasion of easy-to-access power supply. The PT type and coincidence controller are suitable for non-power supply occasions. The intelligent circuit breaker is suitable for radiating type power supply and ring. The network power supply system helps the system to eliminate transient faults, automatically restore power supply, and can also isolate permanent faults, realize distribution network automation, make the circuit breaker have 1-3 reclosing functions, and the recloser parameters can be set, and the intelligent circuit breaker has the switch-on Inrush current control, overcurrent protection and short-circuit quick-break three-stage composite protection, and the parameters can be continuously set.

ZW32-40.5 (ZW32-40.5M/ZW32-35M) intelligent circuit breaker has small current grounding protection function, and the parameters can be continuously set. The intelligent circuit breaker can realize wired remote control or wireless remote control under the pole.

ZW32-40.5(ZW32-40.5M/ZW32-35M) intelligent circuit breaker can be equipped with voltage transformer. The voltage transformer can take power from the high voltage side of the line. It can be supplied to itself or other control equipment 220V, 110V, 100V according to requirements. Voltage, the circuit breaker (small hydropower type) can be used for line voltage monitoring. When over voltage or under voltage, the controller automatically disconnects the circuit breaker, which can be widely used in the branch of the small hydropower branch and the main grid. To achieve network monitoring and automatic isolation of faults, the circuit breaker (metering type) can output 0.2 accurate voltage and current signals, which is an ideal choice for agricultural network substation, off-site scatter switch and simple metering switch.

ZW32-40.5(ZW32-40.5M/ZW32-35M) intelligent circuit breaker can be equipped with electronic PT to charge the battery from CT. It can perform multiple energy storage and opening and closing operations under the condition of voltage loss, and can provide The working voltage of the external equipment has the functions of closing inrush current control, over-current protection and short-circuit and quick-break three-stage composite protection. The protection parameters can be continuously set by the user, which can realize wired remote control or wireless remote control under the pole.
