12kV中置柜加热除湿方式探讨
摘要
12kV中置柜一般都采用电加热方式
并结合防凝露控制器来达到除湿、防凝露的目的
但由于无法在线监测湿度传感器及电加热器是否处于正常工作状态等因素
仍会使防凝露失效而难以杜绝绝缘事故发生。笔者对几种防凝露措施进行比较
推荐一种更为简便而可靠的防凝露方式
Abstract
Generally
Electric heating combined with dew proof controller is used in the 12 kV switchgears to dehumidify and prevent from dew. But the state of humidity sensor and heater can not be surveyed on line
ineffective dew proof will invalidate insulation
the accident always happens. Through comparing several style to prevent from dew
a more convenient and secure one is recommended in this paper.
