Box-type switching station secondary chamber

Abstract

The invention discloses a box-type switching station secondary chamber comprising a power distribution ring main unit body. The bottom end of an empty cavity body is equipped with a suction fan. The top end of the power distribution ring main unit body is equipped with an air outlet which is communicated with the internal cavity of the power distribution ring main unit body. The top end of the internal cavity of the power distribution ring main unit body is equipped with a temperature sensor 1. Multiple secondary chamber bodies are arranged at one side of a baffle. A communicating pipe is arranged at the bottom end of the baffle in a penetrating way. The structure is simple. By adding the empty cavity body, the suction fan can blow air and dissipate heat, and the change of temperature in the secondary chamber bodies is ensured within a reasonable range. If the change of temperature in the secondary chamber bodies is not within an appropriate value range, the secondary chamber bodies are detected through the suction fan, the communicating pipe and a temperature sensor 2, and heat can be dissipated according to the change of temperature in the secondary chamber bodies. Through the communicating pipe, the suction fan can quickly reduce the temperature in the power distribution ring main unit body.

Description

technical field [0001] The invention relates to the technical field of secondary cells of an opening and closing station, in particular to a secondary cell of a box-type opening and closing station. Background technique [0002] With the advancement of science and technology and the improvement of urban power supply facilities in my country, American-style substations and European-style substations have been widely used in our country. This kind of substation is equipped with a closed box with a sliding door, which is called a distribution ring network. In the distribution ring network cabinet, each power supply unit corresponds to an independent power supply secondary cell with a sliding door. Due to the different power consumption of each power supply unit, the temperature difference between the inside and outside of the secondary cell is different. If the temperature inside and outside the secondary cell is too high, the substation and power transmission equipment inside is...

Problems solved by technology

[0002] With the advancement of science and technology and the improvement of my country's urban power supply facilities, American-style substations and European-style substations have been widely used in my country. This kind of substation is equipped with a closed box with a sliding door. This closed box is called a power distribution ring network. cabinet, where each power supply unit corresponds to an independent secondary power supply room with a sliding door in the power distribution ring network cabinet. Since the power consumption of each power supply unit is different, the temperature difference between the inside and outside of the secondary room is different. If the temperature inside and outside the secondary cell is too high, the substation and transmission equipment inside will be easily damaged. If the temperature inside and outside the secondary cell is too low, condensation will occur inside and will affect the safety of the substation and transmission equipment. However, some Some cooling devices are used in the substation equipment, but the cooling devices cannot dissipate heat well, which increases the temperature difference inside and outside the secondary small door, which in turn affects the temperature in the power distribution ring network cabinet, so it will damage the secondary small door. Electronic equipment affects the service life of the power distribution ring main unit
