The one end that cooling fan 3 deviates from the cubical switchboard sets up with the one side parallel and level that preceding baffle 8 deviates from the cubical switchboard, and ventilation hole 2 is located the middle part between baffle 8 about, avoids the condition that 3 front ends of cooling fan are outstanding occupation space.
The national standard states that the temperature rise of the switchgear must not exceed 60K, the touchable part is 30K and the non-touchable part is 40K. Through the understanding of field operation, the high-current switch cabinet with the rated current of 2500A, particularly the main inlet wire cabinet and the enclosed bus generate heat most seriously. When the load current reaches or exceeds 2000A, an enhanced alternating magnetic field is generated at the upper part in the switch cabinet under the combined action of the vertical busbar and the horizontal busbar in the main incoming line, and the magnetic field intensity is in a nonlinear strong increasing trend. The cabinet body and the side plates induce electromotive force and generate a large amount of stray eddy current, and the cabinet body is serious in heating phenomenon due to the fact that the cabinet body is made of magnetic conductive materials and is also large in resistance, and the temperature can reach more than 120 ℃.
Therefore, the heat dissipation air box replaces the original rear protection partition plate of the switch cabinet by processing the trapezoidal air box. Two mute axial flow fans with large air volume are arranged on the trapezoidal bellows. Through temperature control device control, when the temperature reaches the setting value in the cabinet, cooling fan 3 starts, drives the interior air cycle of cabinet outside to the cabinet for the heat gives off fast, reaches the radiating effect.
This heat dissipation bellows wholly adopts the trapezium structural design can make the cubical switchboard get rid of part protecting sheathing 1 back, exposes the distance of part and electrified body and still on safe distance, guarantees personnel and equipment safety. The front end cover of the air box and the box body (namely between the front baffle 8 and the shell 1) adopt a split type design, the heat dissipation fan 3 is fixed on the front baffle 8, the front baffle 8 and the heat dissipation air channel are fixed by hinges and butterfly nuts 13, the fan is convenient to maintain and replace after being opened, and even under an emergency situation, the axial fan can be maintained and replaced under the condition that the switch cabinet does not power off.
Selection of ventilator for general switch cabinets: the volume flow of the fan is =3.1 x (total loss/temperature drop in the cabinet) x 1.5 (coefficient), and the use requirement can be completely met by calculating the axial flow fan with the frame size of 172 x 150 x 51MM and the air volume of 200 CFM.
As can be seen by comparing the temperature measurement of the switch cabinet before and after installation, after the large-current 10KV switch cabinet hanging back type forced radiating air box is installed, the temperature of the cabinet body is reduced by 15-20 ℃, and the effect is very obvious.
