Heat radiation system of electrical cabinets in power distribution room

Abstract

The invention discloses a heat radiation system of electrical cabinets in a power distribution room. The heat radiation system comprises the power distribution room and the plurality of electrical cabinets in the power distribution room, wherein a rainproof roof is arranged on the top of the power distribution room; keels are arranged at the upper part of the power distribution room; suspended ceiling plates are connected below the keels; the power distribution room is divided into an upper space and a lower space by the suspended ceiling plates; an air-conditioning chamber is further formed in each electrical cabinet; the air-conditioning chambers are communicated with a connecting tube; an exhaust tube is correspondingly arranged above each electrical cabinet; the exhaust tubes penetrate through the suspended ceiling plates above the electrical cabinets so that the top parts of the exhaust tubes are positioned inside the upper space of the power distribution room; the bottom parts of the exhaust tubes are communicated with upper openings of corresponding electrical cabinets; a fan is further arranged on the ground of the power distribution room; the outlet tube of the fan is communicated with a blowing tube; the blowing tube is communicated with all air flues. As a plurality of heat radiation schemes are simultaneously implemented, the heat radiation effect is good, and normal operation of electrical elements inside the electrical cabinets of the power distribution room can be effectively ensured.

Description

technical field [0001] The invention relates to the electrical field, in particular to a cooling system for an electrical cabinet in a power distribution room. Background technique [0002] The electrical cabinet is a commonly used electrical product. The electrical cabinet is made of steel to protect the normal operation of the components. The materials for making electrical cabinets are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. Compared with hot-rolled steel sheets, cold-rolled steel sheets are softer and more suitable for the production of electrical cabinets. Electrical cabinets are widely used mainly in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry and so on. [0003] During the use of the electrical cabinet, the internal electrical components will generate heat, which will increase the temperature ...

AI Technical Summary

Problems solved by technology

[0005] 1. Adopt the scheme of installing a fan in the electrical cabinet. Since the fan will vibrate when it is working, this vibration will be transmitted directly to the electrical components inside it through the cabinet body. When various electrical components are in a vibrating state for a long time, their internal The components are easily damaged, which affects the service life. On the other hand, various connecting lines and contacts are also disengaged due to long-term vibration, causing the entire system to fail. Therefore, there are problems in the scheme of using an internal fan;

[0006] 2. The electrical cabinet is generally placed in the electrical control room. If the electrical control room is not equipped with an air conditioner, the temperature of the entire electrical control room will be very high, especially in summer, due to the high temperature of the external air, the fan in the electrical cabinet has to work for a long time; In addition, if an air conditioner is installed in the electrical control room, most of the cold air generated by the air conditioner is building energy consumption, that is, the air in the entire electrical control room needs to be cooled, so the energy consumption will be high, which is not cost-effective;

[0007] 3. The control core in the electrical cabinet: the controller does not have a separate heat dissipation structure. Once the controller fails due to untimely heat dissipation, it will paralyze the entire system and cause immeasurable losses

[0008] Because there are above-mentioned technical problems in prior art, affect use, therefore must improve

[0009] The company has developed an electrical cabinet and its heat dissipation control method (application number 2015102008568), which is beneficial to the air duct located on the top of the power distribution room to dissipate heat, but the air duct is complicated to make, the volume is small, and the convection effect is poor, so the company made another further improvements
