The invention relates to the technology of connecting terminal over-temperature monitoring, and particularly relates to a special device for a chemical temperature changing head. The special device for the chemical temperature changing head solves problems that an existing connecting terminal over-temperature monitoring device is wasteful in labor, cumbersome in operation, liable to damage an original wiring relation of a power distribution cabinet, liable to increase difficulty in wiring of the power distribution cabinet and liable to increase daily repairing points and maintenance amount of the power distribution cabinet. The special device for the chemical temperature changing head comprises a pedestal, a heat conductive plug and a material placing container. The pedestal comprises a case-shaped body. The heat conductive plug comprises a rectangular body, a thick cylinder body and a thin cylinder body. A U-shaped channel is arranged between the top end surface of the thin cylinder body and the left part of the top surface of the rectangular body in a communicating way. The U-shaped channel is internally filled with a heat conductive agent and a catalyst. The material placing container comprises a tube body. The inner cavity of the tube body is filled with the heat conductive agent and a temperature sensing agent. The special device for the chemical temperature changing head is applicable to the fields of electric power, chemical industry, rail transportation, etc.
Description
technical field [0001] The invention relates to a terminal overtemperature monitoring technology, in particular to a special device for a chemical temperature variable head. Background technique [0002] During the actual use of the power distribution cabinet, its terminals are usually prone to temperature rise due to abnormal contact (such as loose screws, thickened oxide layer, etc.), resulting in failures. Therefore, in order to prevent the occurrence of the above faults, it is necessary to monitor whether the terminal is overheated in real time. Under the existing technical conditions, over-temperature monitoring devices for terminal blocks are mainly divided into temperature display stickers, temperature sensors, and infrared thermometers. Among them, the over-temperature monitoring principle of the temperature-indicating sticker is as follows: paste the temperature-showing sticker on the terminal, once the temperature of the terminal rises, the color of the temperatur...
