Problems solved by technology

However, when the temperature difference between the inside and outside of the cabinet-type substation is too large, it is easy to accumulate moisture, which increases the humidity inside the substation, and the equipment in the cabinet-type substation is eroded by moisture, which affects the working stability and even endangers its service life.

Abstract

The invention provides a damp-proof type power transformation cabinet. The damp-proof type power transformation cabinet comprises a cabinet body, a ventilation module, a radiating module, and a control module, wherein a device for electric energy conversion and transmission is installed in the cabinet body, an air inlet and an air outlet are formed in the cabinet body, the ventilation module comprises a first fan, a second fan, a dehydrating breather, an air supply pipe and an air exhaust pipe, the radiating module is installed in the cabinet body and used for reducing temperatures in the cabinet body, the control module comprises a first humidity sensor, a second humidity sensor, an early warning unit and a control unit, and the control unit is respectively connected with the first humidity sensor, the second humidity sensor, the first fan, the second fan, the dehydrating breather and the early warning unit and controls the first fan, the second fan, the dehydrating breather, and the early warning unit to work according to detection data from the first humidity sensor and the second humidity sensor. The damp-proof type power transformation cabinet is capable of automatically dehumidifying the inside of the power transformation cabinet, preventing devices in the power transformation cabinet from being eroded by humidity, and guaranteeing work reliability.

Description

technical field [0001] The invention relates to the technical field of power transformation, in particular to a moisture-proof power transformation cabinet. Background technique [0002] At present, due to its low cost and convenient maintenance, the box-type substation has gradually attracted people's attention, and its application range has become wider and wider. It has gradually replaced substations in various urban and rural areas. [0003] Due to the concentrated distribution of multiple devices in the cabinet type substation, the space is small and the heat dissipation is difficult. The substation will release a lot of heat during the working process, which will cause the temperature to rise and affect the reliability of the internal equipment. When the substation works at high temperature for a long time, it may even cause a fire hazard. [0004] At present, many cabinet-type substations have their own cooling devices to solve the heat dissipation problem, realize t...
