Problems solved by technology

With the advancement of technology, the integration of products is getting higher and higher. In order to ensure the long-term stable operation of the system, this poses a challenge to the cooling solution of the power supply. The usual method is to add a fan near the power supply, and then open the ventilation on the chassis hole, the disadvantage of this approach is that the inside of the device is prone to dust

Abstract

The invention relates to a cabinet of an electric railway protection and monitoring device, which comprises a front panel, a cabinet body, a power supply module and a function module, wherein the front panel is connected to the front side of the cabinet body, and the power supply module and the function module are inserted in the back side of the cabinet body. The cabinet is characterized in that the power supply module comprises a switching power supply, and a heat conduction block is fixed on the cabinet body; and one side of the switching power supply is in contact with one side of the heat conduction block. Compared with the traditional fan cooling mode, the heat radiation scheme in the invention has the advantages of no noise and reliable performance, and the cabinet body is completely closed, thereby avoiding the invasion of dust.

Description

(1) Technical field: [0001] The invention belongs to the technical field of automation control, and in particular relates to a casing of an electrified railway protection measurement and control device. (two) background technology: [0002] The electrified railway protection measurement and control device (hereinafter referred to as the protection measurement and control device) is an important product widely used in the field of automation control. With the advancement of technology, the integration of products is getting higher and higher. In order to ensure the long-term stable operation of the system, this poses a challenge to the cooling solution of the power supply. The usual method is to add a fan near the power supply, and then open the ventilation on the chassis The disadvantage of this approach is that dust is easy to enter inside the device. (3) Contents of the invention: [0003] The object of the present invention is to design a casing of an electrified railw...
