Power transformation cabinet with high heat dissipation performance

Abstract

The invention discloses a power transformation cabinet with high heat dissipation performance. The power transformation cabinet comprises a shock absorption and heat dissipation shell, a sliding rod is fixedly connected between the left and right inner walls of the shock absorption and heat dissipation shell, two sliding seats and compression springs sleeve the sliding rod in a sliding manner, and the two ends of the two compression springs are fixedly connected with the corresponding sliding seats respectively. The sliding seats are hinged to hinge rods, the other ends of the two hinge rods are hinged to the same power transformation cabinet body, a motor is fixedly installed on the bottom surface of the damping heat dissipation shell, the output end of the motor is fixedly connected with a rotating rod, and the other end of the rotating rod is fixedly connected with fan blades. A power transformation cabinet body vibrates during use, a damping effect on the power transformation cabinet body is achieved, the power transformation cabinet body is effectively protected, dust on a filter screen is removed while damping is conducted on the power transformation cabinet body, and the situation that the heat dissipation efficiency becomes poor due to the fact that the dust blocks the filter screen in the long-term heat dissipation process is prevented.

Description

technical field [0001] The invention relates to the field of transformer cabinets, in particular to a transformer cabinet with high heat dissipation. Background technique [0002] A transformer box is a box in a power system where the voltage and current of electric energy are transformed, concentrated and distributed. In order to ensure the quality of electric energy and the safety of equipment, voltage adjustment, power flow (flow direction and distribution of voltage, current and power in each node and branch in the power system) control and power transmission and distribution lines and Protection of major electrical equipment. Mainly used to protect power facilities. [0003] It is very important for the entire power supply system to ensure constant temperature and humidity inside the power distribution cabinet in the power system. If the ambient temperature is too high, the conductivity of the metal will decrease, the resistance will increase, and the surface oxidati...

AI Technical Summary

Problems solved by technology

If the ambient temperature is too high, the conductivity of the metal will decrease, the resistance will increase, and the surface oxidation will intensify; Low, internal stress will be generated in the insulation, which will eventually lead to the destruction of the insulation

In the case of high humidity, condensation or dripping water will easily appear inside the substation cabinet, which will seriously damage the insulation performance of the switch cabinet, and cause serious accidents such as electric shock, arc, and equipment fire. Therefore, the temperature inside the cabinet is too high, Too low or too high humidity will have a negative impact on power distribution, and even affect the entire power grid. In severe cases, explosions may occur, and the substation cabinet will vibrate during long-term work, which will have negative impact on the main body of the substation cabinet The wear and tear will shorten the service life, so it is very important to solve the problem of constant temperature and humidity in the cabinet
