Description

technical field

[0001] The invention relates to a high-voltage electrified body temperature monitoring system based on a wireless transmission mode, which belongs to the field of remote monitoring systems. Background technique

[0002] The power system is developing rapidly towards the direction of large power grid with high reliability and high automation level. The level of automation and intelligent monitoring of power grid operation has become a key issue that is highly valued at home and abroad. With the increasing power consumption, the power load of high-voltage electrical equipment such as transformers, high-voltage switchgear, and knife switches, which carry large power transmission tasks, is also increasing rapidly. Many high-voltage electrical equipment in the power grid itself and the connection point between the equipment are the weakest link in power transmission. The real problem of this weak link is the heating of the connection point. As the load increases...
