Description
技术领域 technical field

背景技术 Background technique
公知的，室内变电站目前存在的事故隐患较多，其中在盛夏高温季节，由于环境温度本身就较高，再加上变电站设备的内部电器部件发热，使得室内环境温度较高，从而使设备超高温运行；如果设备长时间运行在超高温状态下，容易发生的事故，且加速设备的老化，缩短设备的使用寿命；因此，必须使室内通风降温；当雨后及梅雨季节环境中湿度较高的情况下，高压电器柜壳体及内部机构会产生凝露水滴，当积累一定程度后会滴水，从而造成局部放电或断路，引发事故；因此，当室内湿度较高时，必须对室内进行抽湿。目前的除湿方法是在变电站设置通风窗，当时内湿度达到设定值时，传感器启动风扇对室内湿度外排，进一步使室内变保室内湿度及温度处在正常范围内；上述被动除湿方式分不清室内外的湿度差别，在室外湿度较高时启动风扇必然会造成室内外的高湿度气体抽入变电站，达不到预期效果。 As we all know, there are many hidden dangers of accidents in indoor substations. In the midsummer high temperature season, due to the high ambient temperature itself, coupled with the heating of the internal electrical components of the substation equipment, the indoor ambient temperature is relatively high, resulting in ultra-high temperature of the equipment. If the equipment is operated at ultra-high temperature for a long time, accidents will easily occur, and the aging of the equipment will be accelerated, and the service life of the equipment will be shortened; therefore, indoor ventilation and cooling must be done; Under normal circumstances, the high-voltage electrical cabinet shell and internal mechanisms will produce condensation water droplets, which will drip after accumulating to a certain extent, resulting in partial discharge or open circuit, causing accidents; therefore, when the indoor humidity is high, it is necessary to dehumidify the room . The current dehumidification method is to set ventilation windows in the substation. When the internal humidity reaches the set value, the sensor starts the fan to discharge the indoor humidity, so as to further make the indoor substation keep the indoor humidity and temperature within the normal range; the above passive dehumidification methods are different Clear the difference in humidity between indoor and outdoor. When the outdoor humidity is high, starting the fan will inevitably cause the indoor and outdoor high-humidity gas to be drawn into the substation, which cannot achieve the expected effect.
