Series outdoor AC high-voltage vacuum circuit breakers (hereinafter referred to as circuit breakers) are rated voltage, three-phase AC outdoor power distribution equipment. It is mainly used to break and close the load current, overload current and short-circuit current in electronic systems. It is suitable for protection and control in power distribution systems of substations and industrial and mining enterprises, as well as in places where rural power grids are frequently operated. It can also be used as a sectional switch of the power grid. After adding a controller, the distribution network automation can be realized.
Structural characteristics:
The circuit breaker adopts a three-phase pillar structure, which has the characteristics of stable and reliable breaking performance, no danger of combustion and explosion, maintenance-free, small size, light weight and long service life.
. The circuit breaker adopts a fully enclosed structure with good sealing performance, which helps to improve moisture-proof and anti-condensation performance. It is especially suitable for use in cold or humid areas.
The three-phase pillars and current transformers are insulated with imported outdoor epoxy resin solid insulation, or indoor epoxy resin wrapped with silicone rubber solid insulation, which has the characteristics of high and low temperature resistance, ultraviolet resistance, and aging resistance.
. The circuit breaker can be equipped with two-phase or three-phase current transformers for over-current or short-circuit protection. It can also provide current acquisition signals to the intelligent controller and can be equipped with metering current transformers according to user requirements.
The circuit breaker can be equipped with an external three-phase linkage isolating switch. When the isolating switch is in the open state, there is a clearly visible fracture, and it is equipped with an anti-mistake interlocking device with the circuit breaker body. Only when the isolating knife is fully closed The circuit breaker can only be operated when the circuit breaker is turned off or fully opened. The arrester pillar insulator can be connected for easy maintenance.
Product features:
Ideal equipment for urban and rural power grid transformation:
