Vacuum circuit breaker technology advances sunshine vacuum circuit breakers, vacuum circuit breaker technology advances in the performance of the large-capacity, low overvoltage, intelligence and miniaturization. And this is as a result of advances in vacuum technology, the development and adoption of new technology interrupter technology, new materials and new actuator technologies. According to the inventor of the introduction, this technique can be used as an alternative technology in addition to conventional motor technology, will develop a broader space for development and application of a DC motor. Such as the development of large-capacity DC motor instead of the high-voltage DC power transmission grid AC synchronous generator and converter station equipment, not only can save a lot of converter station construction costs Binzhou vacuum circuit breakers, transformer losses can be greatly reduced. Breaker will be dedicated toward the future, multi-functional, low overvoltage, and intelligent direction. "Mistaken together" because the circuit breaker may have: a DC circuit CKS, two negative ground, so closing the control loop is switched on. 2, the automatic reclosing of a component failure within the relay control circuit switched (such as internal error relay normally open contact closure) Zibo vacuum circuit breakers, circuit breaker closing. 3, closing the contactor coil resistance is too small, and the starting voltage is low, when the DC system instantaneous pulse will cause nuisance breaker closing. Zibo vacuum circuit breaker | Vacuum breaker | Huayi electricity provided by Xian Huayi power plant. Xian Huayi power plant (www.xahy.com) strong, credible, in Xi'an high-voltage circuit breakers and other industry has accumulated a large number of loyal customers.
