3000m Altitude Electrical Vacuum Circuit Breaker AC Automatic Reset

High Voltage Electrical Vacuum Circuit Breaker AC Automatic Reset Outdoor Used Vacuum Circuit Breaker

 
 
Product Description:

The ZW8-12 high-voltage vacuum circuit breaker is designed specifically for outdoor use in high-voltage switchgear systems. Its main purpose is to control and protect distribution systems in 10kV urban and rural power grids. It operates at a rated voltage of 12kV and a rated frequency of 50Hz, making it suitable for three-phase AC outdoor high-voltage switchgear.
One of the key functions of the ZW8-12 circuit breaker is to switch on or off load currents in the power system. Additionally, it is responsible for interrupting short-circuit fault currents that may occur, ensuring the safety and stability of the electrical network.
The circuit breaker employs a vacuum interrupter to extinguish the arc that forms when the breaker opens during switching operations. Vacuum interrupters are known for their reliability in interrupting electrical arcs. They possess high dielectric strength and deliver excellent electrical performance.
The ZW8-12 circuit breaker has gained widespread popularity due to its extensive usage, stability, and maturity in power systems. Its successful operation over a long period, along with its proven reliability, has established its reputation in the industry. The breaker has undergone rigorous testing to ensure it meets the required industry standards for performance and safety.

 
  
Feature:

1.The ZW8-12 outdoor high-voltage AC vacuum circuit breaker features enhanced anti-pollution capability, with internal insulation designed for both air and epoxy resin composite insulation. This insulation system helps protect the circuit breaker from environmental pollutants, ensuring its reliable operation even in polluted or harsh outdoor conditions.

2.The ZW8-12 circuit breaker is equipped with a missile energy storage operating mechanism. This mechanism utilizes stored energy to efficiently operate the circuit breaker, enabling quick and reliable switching operations. The missile energy storage mechanism enhances the overall performance and reliability of the circuit breaker.

3.The ZW8-12 circuit breaker can be configured with either a one-side (left side) or two-side separation switch, along with an external PT (Potential Transformer). This flexibility allows for versatile installation options based on specific system requirements. The one-side or two-side separation switch enables easy isolation of the circuit breaker from the power system, while the external PT facilitates accurate voltage measurement and monitoring.
