Abstract

The invention discloses a temperature and PD dual-parameter monitoring device for a power cable joint. The device consists of a temperature measurement unit, a combined power supply unit, a PD measurement unit, an MCU main control unit and a WiFi / 2G / 3G / 4G multi-channel unit. The WiFi / 2G / 3G / 4G multi-channel unit automatically selects the network according to the wireless signal situation at the installation point of the monitoring device. Dual-parameter monitoring helps to find fault symptoms of cables and realize fault warning; the digital temperature sensor improves the reliability and consistency of measurement with the help of pre-embedded and redundant specification installation technology inside the connector. The energy-taking CT coil with an open snap-fit ​​structure, as well as the overvoltage protection and impact protection circuits, improve the reliability of the induction power supply; the induction power supply + lithium battery backup power constitute a combined power supply, and the combined power supply has a simple structure and Reliable performance.

Description

technical field [0001] The invention belongs to the technical category of power cable monitoring devices; in particular, it refers to the collection of temperature and PD dual parameters of power cable joints, the temperature sensor application joint internal embedded and redundant specification installation technology, through WiFi / 2G / 3G / 4G multi-channel module It is a monitoring device for data transmission, induction power acquisition + lithium battery combination power supply. Background technique [0002] The reliability of grid power supply is related to the smooth progress of production and the quality of life. With the expansion of the coverage of the power grid, the fault spreads to the area and causes more and more negative impacts. On August 14, 2003, the United States and Canada experienced a large-scale power outage. The power supply was interrupted for 29 hours, and more than 50 million people were affected; on July 30, 2012, India suffered a large-scale power...
