摘要
探讨了对小型断路器(MCB)温升影响的因素,分析了外壳的导热系数对温升的影响,介绍了导热系数的测量方法,验证了外壳材料对温升的影响作用。试验结果证明,外壳导热系数高MCB可以得到相对较低的温升。
This paper studied the factors of miniature circuit breaker( MCB) temperature rise. Enclosure's thermal conductivity for temperature rise was analyzed. Thermal conductivity 's measurement was introduced. It verified that the higher thermal conductivity,the lower temperature rises.
