Product Description

Outdoor high-voltage vacuum circuit breaker is a circuit breaker that uses vacuum as an arc extinguishing and insulating medium. It can effectively break and close the load current, overload current and short circuit current in the power system, so as to protect the safe and stable operation of the power equipment and power system. ZW32-12 type outdoor column vacuum circuit breaker is a new generation of products developed by our company. The switch structure is compact, the layout is reasonable, and the function is complete. The unified parameter protection CT, zero sequence CT and zero sequence voltage sensor has the characteristics of wide measuring range, high measuring accuracy and high reliability, and complete analog quantity is convenient to accurately determine various line faults.

Zi Kai Outdoor Hv Vacuum Circuit Breaker Feature And Application

Feature

Effective breaking and closing: Outdoor high-voltage vacuum circuit breaker can accurately control the current on and off. Under normal conditions, it can smoothly turn off the load current; In the event of failure, it can quickly break the overload current and short circuit current to prevent excessive current from causing damage to the power equipment.

Protect power equipment: By quickly cutting off the fault current, the circuit breaker effectively protects transformers, cables, generators and other power equipment from damage.

Ensure the stability of the power system: In the power system, any failure can trigger a chain reaction that affects the stability of the entire system. The outdoor high-voltage vacuum circuit breaker prevents the fault from expanding by cutting off the fault source in time.

Adapted to outdoor environment: Because it is designed for outdoor installation, outdoor vacuum circuit breakers have waterproof, dustproof, anti-corrosion and other characteristics, and can work normally in harsh natural environments. At the same time, they also have high mechanical strength and weather resistance to cope with extreme weather conditions such as strong winds, snow and ice.

Application

Power system: used for power system switching and closing operation, especially in the need for frequent operations, such as substations, power plants, etc.

Rural and urban power grids: Distribution systems for rural and urban power grids to ensure the safe and stable operation of the grid.

Industrial field: In mining, metallurgy, chemical industry and other industrial fields, used to protect power equipment and control power processes.
