ZW32-40.5 Outdoor pole-mounted vacuum circuit breaker automatic recloserZW32-40.5 series outdoor high-voltage vacuum circuit breaker (hereinafter referred to as "circuit breaker") is used in three-phase power systems with AC 50Hz and rated voltage 35kV to divide and combine load current, overload current and short-circuit current. The circuit breaker can be configured with a reclosing controller that can identify current characteristics and realize multiple automatic reclosing. It has its own PT as a power supply, becoming an intelligent circuit breaker with voltage and current signal output and controllable; the electronic PT provides power and can complete overcurrent Three-stage composite protection of time delay, inrush delay and short-circuit quick-break.
Structure schematic
Features
1.1 The overall circuit breaker is of miniaturised design and of fully enclosed structure. The spring-operated mechanism is hermetically arranged inside the case.
1.2 The circuit breaker body is mainly composed of conductor circuit, transmission system, insulation system and so on.
1.2.1 conductive circuit mainly consists of inlet and outlet conductive rod, conductive bracket, vacuum interrupter room, etc., vacuum interrupter room is the main component of the circuit breaker, the use of ceramic shell, cup-shaped longitudinal magnetic contact structure, copper-chromium contact material, has a good opening and closing short-circuit current capacity, long electric life. Avoid a series of problems caused by oil filling and gas filling.
1.2.2 Transmission system mainly consists of three-phase spindle, insulated tie rod, inflection arm, contact spring and split spring.
1.2.3 Circuit breaker can have current transformer in two phases, according to the user's needs can be installed 50/5, 100/5. 150/5. 200/5. 400/5. 630/5 and other specifications.
1.3 circuit breaker operating mechanism by the closing bullet, energy storage system, overcurrent disconnectors, switching system, etc., can be divided into two kinds of manual electric operation.
1.3.1 Manual operating mechanism with manual energy storage, manual breaking, closing and overcurrent protection, such as users need to install surge current delay protector, that is, with overcurrent delay protection.
1.3.2 Electric operating mechanism shall be powered by independent power supply, in addition to electric energy storage, electric switching, closing and overcurrent protection, but also has a manual energy storage, manual switching and overcurrent protection. If the user needs to install inrush current time-delay protector, that is, with overcurrent time-delay protection.
1.4 Circuit breaker can also be equipped with intelligent switch controller, with three-stage current protection, zero sequence protection reclosing. Quick-break protection and other protection functions. It supports a variety of communication protocols, allowing the use of a variety of communication methods to form a communication network, the switch can be manually or remotely operated locally, but also through the communication network to achieve remote control. If equipped with corresponding reclosing or sectional control device, it can be used as recloser or sectionaliser.
The circuit breaker can be used as recloser or sectionaliser if equipped with corresponding reclosing or sectional control device.
1.5 The installation mode of the circuit breaker adopts the column mounting type.
