摘要
小型断路器现已频繁的应用在家庭场所及类似场所中,因此如何安全使用小型断路器具有十分重要的意义。而电路中总会出现短路、过载等意外情况,因此要求小型断路器要及时分断。如若小型断路器不能及时分断,过高的短路电流则会造成小型断路器的发热、熔焊等现象,进而对下级设备造成损害。本文主要分析小型断路器发生分断的原因及情况,研究分断过程中合闸角对其焦耳积分所产生的影响,进而对小型断路器的脱扣情况产生的影响。更好地保护小型断路器及下级设备。国内外对发生电路故障时小型断路器所产生的分断电流值其影响的因素进行了研究,为研究在何种条件下小型断路器的脱扣器脱扣,国内外对其所产生的不同分断电流进行了测试。
Miniature circuit breaker has been frequently applied in domestic areas and similar places, so how to safely use miniature circuit breaker is of great significance. And circuit always appear the accident situation such as short circuit, overload, therefore requires and miniature circuit breaker at the break. If small circuit breaker and time- division, high short circuit current will cause fever, such as welding phenomena of the miniature circuit breaker, and damage to equipment at a lower level. This article mainly analyse the reason of breaking and miniature circuit breaker, switching angles in the research process of breaking the joule integral effects, on the impact of miniature circuit breaker tripping situation. To better protect small circuit breaker and at a lower level equipment. For circuit fault occurs at home and abroad of miniature circuit breaker breaking current value its influence factors are studied, under what conditions for research of miniature circuit breaker tripping device tripping, both at home and abroad for its different breaking current generated by the test.
