Xi'an vacuum circuit breaker ZW8-12/630-20 manufacturer

Product Overview Product Model and Name
Xi'an Vacuum Circuit Breaker-
Main Applications
-Series outdoor high-voltage vacuum circuit breakers (hereinafter referred to as circuit breakers) are high-voltage outdoor switching equipment with three-phase AC rated voltage. It is mainly used to switch on and off the load current, overload current and short-circuit current of rural power grid, urban power grid and small power system. The overall structure of the product is a three-phase common box type. The three-phase vacuum arc extinguishing chamber is placed in a metal box. It uses insulating materials for inter-phase insulation and ground insulation. It has reliable performance and high insulation strength. The operating mechanism of this series of products is a type 3 spring energy storage operating mechanism, which is divided into two types: electric and manual. The circuit breaker can be configured with a reclosing controller that can identify current characteristics and realize multiple automatic reclosing or isolation of permanent faults. It is self-contained as a power supply and becomes an intelligent circuit breaker with voltage and current signal output and controllable. It is powered by electronics and can complete the process. Three-stage composite protection of current delay, inrush delay and short-circuit quick-break.
-It is composed of a circuit breaker and an isolation knife, which is called a combination circuit breaker. It can be used as a sectional switch to form a combination circuit breaker with an obvious break. Users can choose to use a silicone rubber insulating sheath on the isolating switch. This sheath is resistant to rain, snow, wind and sand, and is resistant to pollution and corrosion, and can effectively prevent freezing and oxidation of the isolating switch.
The circuit breaker can be equipped with a lightning arrester, and the lightning arrester can be installed on either side of the incoming and outgoing lines according to user requirements
The circuit breaker can be equipped with an inrush current controller, which has the function of avoiding inrush currents and quickly breaking overcurrents
The circuit breaker can be equipped with ~3 measuring or metering transformers.
- Equipped with a recloser controller to form a recloser type intelligent circuit breaker. It is suitable for occasions with easy access to power supply when matched with the coincidence controller. It is suitable for occasions without power supply when matched with the coincidence controller. The intelligent circuit breaker is suitable for radial power supply and ring network power supply system to help the system eliminate instantaneous faults and automatically restore power supply. It can also isolate permanent faults and realize distribution network automation.
The smart circuit breaker has ~3 times of reclosing function, and the recloser parameters can be adjusted
The smart circuit breaker has the functions of closing inrush current control, overcurrent protection and short-circuit quick-break three-stage composite protection, and the parameters can be adjusted Continuous setting
The intelligent circuit breaker has a small current grounding protection function, and the parameters can be continuously adjusted
The intelligent circuit breaker can realize both wired remote control and wireless remote control under the pole.
- Cooperating with the voltage transformer, the voltage transformer takes power from the high-voltage side of the line and can provide the voltage to itself or other control equipment as needed
This circuit breaker (small hydropower type) can be used for line voltage Monitoring, when overvoltage or undervoltage occurs, the controller automatically opens the circuit breaker, which can be widely used at the grid-connected branches of small hydropower branches and the main power grid to realize network monitoring and automatic fault isolation
The The circuit breaker (metering type) can output voltage and current signals with .
