Overheat reminding device for power distribution cabinet

Abstract

An overheat reminding device for a power distribution cabinet relates to the technical field of power distribution. The overheat reminding device comprises a cabinet body, wherein a closed cavity is formed in the middle of the cabinet body, a heat conduction block is fixedly connected to the inner wall of the top part of the cabinet body, an air bag fixedly connected with the bottom part of the heat conduction block is fixedly connected to the top part of the closed cavity, sealing blocks are movably connected to the two sides of the top part of the cabinet body, the outer sides of the sealing blocks are sleeved with first springs fixedly connected with the inner wall of the cabinet body, and the bottom part of the air bag is fixedly connected with a piston block movably connected with the inner wall of the cabinet body. According to the overheat reminding device for the power distribution cabinet, through cooperative use of the water storage tank and the closed cavity, when the temperature in the cabinet body is too high, copper sulfate in the closed cavity falls into the water storage tank, the color of water in the water storage tank becomes blue, light emitted by a light emitter is difficult to penetrate through, the illumination intensity of a photoresistor is reduced, and at the moment, the photoresistor is powered off, so that the whole circuit is disconnected, the safe use of the power distribution cabinet is effectively ensured, and the practicability is effectively improved.

Description

technical field [0001] The invention relates to the technical field of power distribution, in particular to an overheat reminder device for a power distribution cabinet. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final equipment of the power distribution system. Power distribution cabinets are collectively referred to as motor control centers. ; The motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby load. This level of equipment should provide protection, monitoring and control for the load. [0003] The current power distribution cabinet is covered with a large number of lines, and each line will generate heat transfer during operation, causing the internal temperature of the ...

AI Technical Summary

Problems solved by technology

[0003] The current power distribution cabinet is covered with a large number of lines, and each line will generate heat transfer during operation, causing the internal temperature of the power distribution cabinet to rise, especially during high temperature periods in summer, the temperature inside the power distribution cabinet is very likely Too high will cause the line to ignite, cause the circuit to burn, cause damage to the power distribution cabinet, and affect the power supply, which will cause delays in the power distribution schedule and cause great inconvenience
