Description

Technical Field

[0001] The utility model relates to the technical field of wireless temperature monitoring, in particular to a novel wireless temperature monitoring system. Background Art

[0002] The power system is developing rapidly towards the direction of high reliability and high automation level of large power grids. The level of automation and intelligent monitoring of power grid operation has become a key issue that is highly valued at home and abroad. The connection points between many high-voltage electrical equipment in the power grid and the equipment are the weakest links in power transmission. The essence of this weak link is the heating of the connection points.

[0003] As the load increases, the connection point heats up and forms a vicious cycle: temperature rise, expansion, contraction, oxidation, resistance increase, temperature rise again until an accident occurs. The temperature monitoring points of high-voltage electrical equipment are in an environment of high voltage, high current, and strong magnetic field. Some monitoring points are even in a closed space. Due to strong electromagnetic noise, high-voltage insulation, space limitations and other issues, the usual temperature measurement method cannot solve these problems and cannot be used.

[0004] The sensor is installed on the high-voltage equipment and has no electrical connection with the receiving equipment. Therefore, the system fundamentally solves the problem of difficult real-time online monitoring of the operating temperature of the high-voltage equipment contacts. The wireless temperature monitoring system has extremely high reliability and safety, and is relatively inexpensive. It can be directly installed on each high-voltage switch, busbar connector, outdoor knife switch or transformer. Utility Model Content
