Main function characteristic

The controller is an intelligent device, that matches sectionalized to reach distribution automation without other control system. Consist of a circuit breaker (with mechanism operation), controller, and control power, besides opening of closing regular and fault current as the circuit breaker, it can repeatedly auto reclosing by advanced setting times for sectionalized to isolate fault circuits when the short circuit fault happens. The non-fault lines will resume the power supply; if repeatedly auto reclosing failed, closing and interlock inside of the controller, another side of the network, originally closing and interlock status will remove interlock and auto closing, non-fault lines resume power supply at once. The network automation could limit the power supply interrupted district to a minimum range, it has high social benefit and economic benefits.

   The product is practical and reliable, multiple functional, the controller uses a microprocessor, the panel shown in digital, conveniently with person-machine talking, all the parameters could be adjusted, a new function of the GPRS communication system could achieve opening, and closing operation and Teradata communication function by mobile phone, it can transmit lines parameters and running state of the equipment. 
   The product adopts ZW20A-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. 

a. 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.
b. 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.
c. 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.
d. 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.
