Electrical control cabinet capable of expanding heat dissipation range

Abstract

The invention discloses an electrical control cabinet capable of expanding a heat dissipation range, and the electrical control cabinet comprises a control cabinet, the front surface of the control cabinet is fixedly connected with a heat dissipation net, the two sides of the front surface of the control cabinet are fixedly connected with supporting blocks, and the top of the front surface of the control cabinet is provided with a baffle plate located on the front surface of the heat dissipation net. The air cylinder is started, the output end of the air cylinder drives the ejector rod to move downwards, the ejector rod drives the toothed plate to move downwards, the toothed plate drives the gear to rotate, the gear drives the connecting rod to rotate, the connecting rod drives the baffle to turn over upwards, and the push plate drives the brush to clean the radiator air net, so that the radiator air net cleaning device has the advantage of expanding the radiating range. The problems that most existing control cabinets dissipate heat through a heat dissipation fan at the top of a cabinet body or a heat dissipation net arranged on the surface of the cabinet body, so that the temperature in the cabinet body is too high in summer, the heat dissipation fan can only blow air to a fixed place and cannot effectively dissipate heat, and internal instruments are damaged are solved; the use performance of the connecting block is improved.

Description

technical field [0001] The invention relates to the technical field of control cabinets, in particular to an electrical control cabinet capable of expanding the heat dissipation range. Background technique [0002] The control cabinet is to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on the screen according to the electrical wiring requirements. The safety of the equipment and surrounding equipment, the circuit can be turned on or off with the help of manual or automatic switches during normal operation, and the circuit can be cut off or alarmed with the help of protective appliances during fault or abnormal operation. Some electrical parameters are adjusted to prompt or send signals for deviations from the normal working state. They are often used in power generation, distribution and substations. Control cabinets are required to protect electrical instruments, but the existing control...

Problems solved by technology

[0003] In order to solve the problems raised in the above-mentioned background technology, the object of the present invention is to provide an electrical control cabinet that can expand the heat dissipation range, which has the advantage of expanding the heat dissipation range, and solves the problem that most of the existing control cabinets pass through the top of the cabinet. The heat dissipation fan or the heat dissipation net on the surface is used for heat dissipation, which leads to the high temperature inside the cabinet in summer. The heat dissipation fan can only blow air to a fixed place and cannot effectively dissipate heat, resulting in damage to the internal instrument and reducing the performance of the control cabinet.
