VT18 series indoor AC high voltage vacuum circuit breaker is suitable for three-phase AC 50 Hz, 24 kV / 40.5 kV system. It can be used for industrial and mining, power plants and substations as load current, overload current and fault current. It is also suitable for frequent operation.

產品特點Product Features

VT18系列戶內高壓交流真空斷路器采用前后布置結構,固定在充氣隔室的內外壁上。斷路器采用敞開式結構，置于SF6氣體室內，這樣有利于主回路散熱，并且能滿足絕緣配合的要求，主回路電氣連接全部采用固定式連接，具有很高的可靠性。

操動機構采用專門為這種新型斷路器設計的彈簧操動機構，安裝在斷路器框架內。其結構特點更適合斷路器的前后布置形式，并成為斷路器整體結構中不可分割的一部分。機構設計簡單，輸出曲線與滅弧室的要求配合良好。

VT18 series indoor AC high voltage vacuum circuit breaker adopts the front and back arrangement structure, which is fixed on the inner and outer walls of the inflatable compartment. The circuit breaker adopts an open structure and is placed in the SF6 gas room, which is conducive to the heat dissipation of the main circuit and can meet the requirements of insulation coordination. The electrical connection of the main circuit adopts fixed connection and has high reliability.

The operating mechanism adopts the spring operating mechanism specially designed for this new type of circuit breaker, which is installed in the circuit breaker frame. Its structural characteristics are more suitable for the front and back layout of the circuit breaker, and become an integral part of the overall structure of the circuit breaker. The design of the mechanism is simple, and the output curve is well matched with the requirements of the arc extinguishing chamber.
