The product adopts ZW20-12 type outdoor AC H.V. vacuum circuit breaker as noumenon, the noumenon switching adopts a vacuum interrupter to arc extinguishing and SF6 gas to isolate, and the case adopts gas sealed, isolation structure technic. No leakiness of internal filling gas, the spring mechanism operation promotes miniaturization and performance optimization design, and operation reliability is more advanced than the domestic traditional spring mechanism. The main circuit is sealed inside the case, it has the advantage of anti-explosion, anti-condensation, anti-nasty, no influence by the outside environment, it is the first choice for controlling and protecting the intelligent electrical network.
1. Main circuit and mechanical operation of circuit breaker are sealed in SF6 gas, not influenced by outside environment, and reaches the requirement of free maintenance and long life.
2. It completes a set with an electronic controller, to realize remote control, remote supervision, remote signaling, and remote-adjusting functions, to achieve electrical network intelligent control requirements.
3. New design of miniaturization electromotive spring mechanism, whole spare parts of the product reduced to Iowest level, increase the reliability and energy saving of circuit breaker.
4. Fixed with the anti-explosion device at the top of the case, to avoid leakiness of high temperature gas and splash even if an accident occurs, ensuring the safety and reliability of the product.
