Abstract

The invention relates to a wireless temperature measurement insulation plug of a cable head, and a working method thereof. The wireless temperature measurement insulation plug comprises an epoxy insulation plug, a columnar groove is formed in the epoxy insulation plug downward from tan upper end face, a wireless temperature measurement body is fixedly arranged in the columnar groove, the wirelesstemperature measurement body comprises a potential difference induction electricity taking module, a wireless transmission module and a temperature measurement module, which are fixedly arranged in the columnar groove, the upper end of the epoxy insulation plug is inserted into an elbow-shaped cable head and is screwed with a fixing bolt that is fixedly arranged in the elbow-shaped cable head viaa shielding cap embedded in the columnar groove, and the wireless temperature measurement insulation plug of the cable head has a simple and reasonable structure, and solves the problem that the actual temperature in the elbow-shaped cable head cannot be controlled previously.

Description

technical field [0001] The invention relates to a cable head wireless temperature measuring insulating plug and a working method thereof. Background technique [0002] In the 10kV / 20kV / 35KV cable distribution network, compared with the cable body, the cable terminal head is a weak link and a short board for the safe operation of the cable line. In actual operation, before the failure of the cable head, there is often a process of heating, which accelerates the aging of the insulation, and finally causes a breakdown and short circuit "blasting". During this period, the temperature of the cable head will be much higher than normal, and it will last for a relatively long period of time, so theoretically, it is possible to detect possible defects in time by regularly measuring the temperature of the cable terminal. [0003] At present, operating units mainly rely on infrared thermometers, handheld partial discharge testers and other equipment to regularly inspect power distribu...
