An in-situ installed power secondary equipment that facilitates heat dissipation

Abstract

Disclosed is a secondary electric power equipment installed on-site for facilitating heat dissipation, comprising an aluminium alloy die-casting box body (1), wherein an aluminium alloy cover plate (2) covers and is connected to the aluminium alloy die-casting box body (1); a bottom layer inside the aluminium alloy die-casting box body (1) is installed with a power supply module (3) and an alternating current sampling module (4); an IO module (5) is installed above the power supply module (3) in an overhead manner by means of nuts and bolts; a shielding plate (6) is installed above the IO module (5), with strong electric signals of the secondary electric power equipment being isolated via the shielding plate (6); a constant temperature plate (7) is installed above the alternating current sampling module (4); a communication module (8) is installed above the constant temperature plate (7); and a CPU module (9) is installed on a lower surface of the aluminium alloy cover plate (2). By means of a rational layout of modules inside the equipment, the equipment transfers heat generated by a heating element during operation to an outer wall of the aluminium alloy die-casting box body (1) by using heat conduction technologies such as the constant temperature plate (7) and PCB buried copper, and the heat is then dissipated to the surrounding air. In addition, a ventilating valve is installed, thereby realizing inside and outside air exchange, taking away some heat, and achieving good usage prospects.

Description

technical field [0001] The invention relates to the technical field of substation secondary equipment, in particular to an in-situ installed electric power secondary equipment that facilitates heat dissipation. Background technique [0002] The traditional substation secondary equipment panel is installed in the control room of the substation. There are air conditioners, fans, heaters and other temperature control equipment in the control room to ensure a good operating environment for the secondary equipment. However, the secondary equipment is localized, that is, the secondary equipment is directly installed on the primary equipment or installed next to the primary equipment through a steel frame, and the working environment is changeable. The dependence of the relay protection device and the independence of the relay protection device are maintained, which is the current development trend of domestic smart substations. However, due to the vast territory of our country, t...
