description Since prefabricated cabin substations became a comprehensive application achievement of the new infrastructure intelligent integrated system, its electrical equipment failure, and power system safety due to humidity condensation is of great concern. In this paper, thermoelectric cooling superconducting thermoelectric dehumidifiers (TCSTD) are developed and the optimal operating conditions and the dehumidification performance of the TCSTD under actual operating conditions are investigated through tests. The results show that the optimal dehumidification rate of the TCSTD is 188.4 ml/h when relative humidity is 95% and the outlet air velocity is 2.3 m/s. The addition of TCSTD on top of thermal assistance can further reduce the relative humidity to 53.05%, a reduction of up to 32.36%. TCSTD is used in high temperature, high humidity environments to reduce not only the ambient relative humidity but also the moisture content of the air. The proposal is that attention should be paid to both dehumidification and relative humidity per unit of power consumption to meet the requirements for moisture protection and energy saving in prefabricated cabin substations. The results of the study will provide a reference for the application of the new prefabricated cabin substation.
