The substation will release a large amount 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] In addition, 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 service life, and may even cause hazardous operations such as short circuits. hidden danger to personal safety

Embodiment 1
[0030] Such as figure 1 , figure 2 As shown, a temperature and humidity linkage type transformer cabinet proposed by the present invention includes: a cabinet body 1, a first temperature sensor 2, a second temperature sensor 3, a first humidity sensor 4, a second humidity sensor 5, an adjustment system and a control system module.
[0031] The first temperature sensor 2 and the first humidity sensor 4 are installed inside the cabinet 1 for detecting the temperature and humidity in the cabinet 1 respectively. The second temperature sensor 3 and the second humidity sensor 5 are installed outside the cabinet body 1 for detecting indoor temperature and humidity respectively.
[0032] The conditioning system includes a ventilation structure 61 , an air delivery mechanism, a dehumidification device 62 and a cooling device 63 . The ventilation structure 61 is installed on the cabinet body 1 to discharge the air inside the cabinet body 1. Specifically, a ventilation fan or a throu...
Embodiment 2
[0048] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the first output end of the second three-way valve 66 is connected to the input end of the cooling device 63, and its second output end is connected to the input end of the dehumidification device 62, and the output end of the cooling device 63 is connected to the input end of the cooling device 63. The output end is connected to the input end of the third three-way valve 67 , the first output end of the third three-way valve 67 is connected to the input end of the dehumidification device 62 , and the output end of the dehumidification device 62 is connected to the air outlet pipe 68 .

Abstract
The invention provides a temperature humidity linkage type transformer cabinet. The temperature humidity linkage type transformer cabinet comprises a cabinet body, a first temperature sensor, a second temperature sensor, a first humidity sensor, a second humidity sensor, an adjustment system and a control module, wherein the adjustment system comprises an air exchange structure, an air transmission mechanism, a dehumidifying device and a cooling device, the control module is respectively connected with the first temperature sensor, the second temperature sensor, the first humidity sensor, the second humidity sensor, the air exchange structure, the air transmission mechanism, the dehumidifying device and the cooling device and further controls operation of the air exchange structure, the air transmission mechanism, the dehumidifying device and the cooling device according to detection values of the first temperature sensor, the second temperature sensor, the first humidity sensor, the second humidity sensor. According to the temperature humidity linkage type transformer cabinet, indoor air humidity is automatically monitored, air exchange and air dehumidifying can automatically selected to realize air drying, and high automation and strong timeliness are realized.
Description
technical field [0001] The invention relates to the technical field of transformer cabinets, in particular to a temperature-humidity linkage type transformer 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] In addition, when the temperature difference between the inside and outside of the cabinet-type substation is t...
