  1. Based on the comprehensive study on contact erosion and massive tests, it is found that the erosion of cb contacts is dominantly depend on the arcing time and breaking current. this paper analyses the mechanism of electrical arc of vacuum circuit breaker and discusses the primary factores. then this paper put forwardes a way to prognosticates the life exepctancy of electrical endurance of vacuum circuit breaker base on the power of arc

    本文分析了真空斷路器的燃弧機理，探討了影響真空斷路器電壽命的主要因素，指出了原先以開斷電流作為預測真空斷路器電壽命的方法的不足，提出了改進的以燃弧能量為主要指標的預測方法。
  2. Electrical contact electrical arc

    電接觸與電弧
  3. Electrical arc contact

    電弧電接觸
  4. At present, the arc contacts in sfe switches is formed by the excellent property of electrical arc resistance of cu w alloy and the eminent conductivity together with high elasticity of crcu alloy, so - called cuw / crcu integrated contact

    目前在sf _ 6斷路器中普遍使用的觸頭材料一般由耐電弧燒損的cuw部分和提供彈性和導電性的crcu部分組成，即cuw crcu整體觸頭。
  5. Switches play transmitting and cutting electrical current role during the working electrical net as a hinge, the important role will be brought into effect by the key part in switches - arc contact. if the contacts have invalidated and could not accomplished the important role during the working electrical net, switches would detonate, which result in the paralysis of whole net linked by the switches, the higher the transmitting voltage of net is, the bigger the affected area is, therefore, in order to decrease or avoid the arc eroding and invalidation during the net working, it is necessary to study the arc eroding and invalidation mechanism of contacts, sequentially make the whole net stable

    可以說是電網中樞紐，而實施斷路器重要作用的核心部件就是弧觸頭，如果在動態使用中由於觸頭的失效而不能有效開斷的話，斷路器就會整機爆炸，後果就是它所連接的整個電網處于癱瘓狀態，電網的輸變電電壓越高，波及的面積越大，所以有必要對觸頭的動態燒損和失效進行詳盡的分析，減少或避免實際使用過程中的燒損和失效，從而穩定整個電網。
  6. Standard guide for arc erosion testing of electrical contact materials

    電接觸材料的電弧侵蝕試驗的標準指南
  7. The arc moving process of low voltage apparatus plays an important role for the disjunction ability of the contact, electrical life and its cause of invalidation

    低壓電器電弧的運動對電器的分斷能力、電壽命以及判斷電器是否發生故障都起著相當重要的作用。
