| 摘 要： | 通过对户内小车式真空断路器与母线连接动静触指烧损故障的分析和计算,阐述了造成触指烧损故障的原因,并进而说明断路器型式试验仅作峰值耐受电流和短时耐受电流试验是不够的,尚应增加额定电流下温升试验,以杜绝该类故障的发生。

| Abstract: | s: This paper depicts the reasons of damage to the movable and motionless contacts of the indoor cart type circuit breaker through analysis and calculation of the fault of the circuit breaker, and further describes that it is insufficient to carrying out the with-standing tests of peak current and short time current as the type tests of the circuit breaker, it is necessary to add the test of temperature-rise at rated current in order to avoid the occurrence of such fault. |
