The co2 welding process needs the special external characteristic and dynamic characteristic of power source for there are alternately arcing time and short circuiting time at the period of short - circuiting co2 welding
在采用短路过渡方式的co2焊过程中,短路和燃弧过程交替发生,因此它对电源的外特性和动特性有特殊的要求。
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
本文分析了真空断路器的燃弧机理，探讨了影响真空断路器电寿命的主要因素，指出了原先以开断电流作为预测真空断路器电寿命的方法的不足，提出了改进的以燃弧能量为主要指标的预测方法。
