Has a strong vacuum insulating property, in the vacuum circuit breaker, the gas is very thin, the free path of gas molecules is relatively large, the probability of occurrence of collision is small, and therefore the price of the circuit breaker Jinan, collision free vacuum gap breakdown is not a major Cause of Jinan main circuit breaker price, and in the high-strength electric field by the electrode deposited metal particle is caused by dielectric breakdown. The dielectric strength of vacuum gap not only with the size of the gap, the homogeneous electric field, but also to a greater impact properties and the surface condition of the electrode material is acceptable. Vacuum gap in the gap at small distance (2-3 mm) case, there is high pressure air and SF6 gas high insulating properties, which is a vacuum circuit breaker contacts from the general is not the cause of the contacts are open large current, arc energy increases, the anode is also a serious fever, the formation of strong centralization of the arc column. At the same time, the role of electric power is also evident in Jinan breaker price, therefore, the magnetic field distribution of high-current vacuum arc between the contacts will have a decisive impact on the stability and performance of the arc extinction. If the current is too large, breaking current exceeds the limit, it will cause a breaking failure. In this case, the contact heat seriously, the current is still zero crossing after evaporation, media recovery is difficult, you can not disconnect the current.
