地铁变电所内成套开关设备防潮除湿分析及措施

变电所一般不设置于地下室,但一些工程因本身即为地下建筑,如地铁、地下商场、人防市政地下工程等,需要将变电所设置在地下室,但不宜设在建筑地下的最底层.故此对变电所及其内装设的成套开关设备的设计提出了更高要求,需要考虑多维度综合的防护措施.故有必要分析成套开关设备导致其内部潮湿的原因,介绍解决相应问题所使用的措施,避免成套开关设备因潮湿而出现危险状况,保证电力系统的安全稳定运行.

Analysis and measures for moisture proof and dehumidification of switchgear in Metro substation

The substation is generally not set up in the basement, but some works for itself is the underground buildings, such as the subway, underground shopping malls, underground municipal civil air defense engineering, substation needs to be set in the basement, but the bottom of the building is located in the underground. So put forward higher requirements for design of switchgear the substation and installed within the need to consider the protection measures of multi dimension. So it is necessary to analyze the switchgear leads to the moisture inside reason, introduced to solve the corresponding problem by the use of measures to avoid switchgear due to damp and dangerous situation, to ensure the safe and stable operation of power system.
