- 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.
