关于真空断路器强制风冷风机风量的计算

摘要

户内高压开关设备由于受到结构、空间及成本的限制，真空断路器自然冷却可能不满足GB标准的要求，这时往往采用的强制风冷的方法进行冷却。由于开关设备温升是一个发热和散热的动态平衡的过程，详细计算比较困难。本文旨在通过简易计算，方便确定强制风冷风机风量。%Due to the indoor high-voltage switch equipment constrained by the structure, space and cost, natural cooling of vacuum circuit breaker may not meet the requirements of GB standard, so it needs the method of force-air cooling. Because the switching equipment temperature rising is a dynamic balance process of heating and dissipation of heat, the calculation is more difficult. This article is to determine the air flow of force-air cooling fan through simple calculation.
