- 摘要:
- 针对地下污水厂箱体内相对湿度较高而影响电气设备安全运行的问题，首先分析了湿度对电气设备的影响及产生原因，其次对电气设备外部环境除湿和内部除湿进行了比较，并进一步从原理、实验分析、实际应用效果等方面，对电气设备内部采取的加热和半导体冷凝两种除湿方式做了分析比较，提出地下污水处理厂电气设备宜采用半导体冷凝除湿方式，应用案例证明了该除湿方法的可行性和有效性。
- Abstract:
- The high relative humidity in the underground sewage treatment plant will affect the safe operation of electrical equipment. The influence and causes of humidity on electrical equipment were analyzed, and the external environmental dehumidification and internal dehumidification of electrical equipment were compared. Furthermore, the two dehumidification methods of heating and semiconductor condensation adopted in the electrical equipment were analyzed and compared from principle, experimental analysis and practical application effect. The semiconductor condensation dehumidification method was proposed for the electrical equipment of underground sewage treatment plants, and its feasibility and effectiveness were proved.
