vacuum interrupter contactor,vacuum bottle for contactor

12KV vacuum bottle interrupter is the core of the low voltage circuit breaker research and development. The performance of the interrupter is directly related to the breaking performance of the low-voltage circuit breaker, which determines whether the product can meet the requirements of intelligent, highly reliable new current selective protection and fault location. To this end, domestic and foreign scholars and research institutions have been committed to the field of technical research, and access to a large number of applications, such as through the double breakpoint arc technology to improve the arc voltage and mechanism speed; through gas production of reasonable settings, Improve the arc voltage and dielectric recovery strength, etc., to effectively improve the product breaking performance. At present, the design and analysis of the low-voltage circuit breaker arc chamber is mainly through the test method and simulation analysis method. The experimental method mainly uses ...

Vacuum circuit breaker insulation is divided into fracture insulation, interphase insulation and insulation to the ground. vacuum interrupter in the vacuum circuit breaker in addition to breaking the working current and short circuit current, but also bear the task of fracture isolation. At present, the manufacturer of interrupter is good and bad, in order to ensure the vacuum circuit breaker in the safe and reliable operation of the power system, vacuum interrupter as the core of the vacuum circuit breaker device to ensure its insulation capacity, select the quality assurance manufacturers is essential The Vauum interrupter contactor insulation is divided into internal insulation and external insulation, the internal insulation is divided into static insulation and dynamic insulation. In the type test, the insulation of the vacuum interrupter mainly assess the short-time power frequency withstand voltage and lightning impulse withstand voltage, and in actual use, due to grid conditi...
