摘要

针对操动机构加热器参数设计的问题,开展高压断路器用弹簧操动机构加热器的温湿度数值仿真研究,分析环境温度、功率、尺寸等参数对机构箱内温度分布的影响规律。结果表明：加热器周围及正上方的空气温度最高、相对湿度最低,随着空气的横向流动,空气温度逐渐降低、相对湿度有所升高;环境温度和加热器的功率对操动机构箱体内的最低温度、最大相对湿度及加热器表面最高温度的影响非常显著;加热器尺寸对操动机构箱体内的最低温度和最大相对湿度的影响很小,但对加热器表面最高温度的影响比较显著。

Abstract：

Aiming at the design of the heater in the operating mechanism box, a numerical simulation study on the temperature and humidity of the heater in the operating mechanism box for high voltage circuit breakers is carried out, and the influence of environmental temperature, power, size and other parameters on the temperature distribution in the mechanism box is analyzed. The results show that the air temperature around and directly above the heater is the highest and the relative humidity is the lowest. As the air flows laterally, the air temperature gradually decreases and the relative humidity increases. The environmental temperature and the heating power of the heater have a significant effect on the minimum temperature, maximum humidity and the surface temperature of the heater in the operating mechanism box. The heater size has little effect on the minimum temperature and maximum humidity in the operating mechanism box, but it has a significant effect on the maximum temperature of the heater’s surface.

Key words： operating mechanism heater temperature humidity numerical research
