Problems solved by technology

[0003] The purpose of the present invention is to provide a wireless temperature online monitoring device of a fully enclosed combined electrical appliance GIS. In the combined electrical GIS, since the measured conductive parts are all enclosed in insulating gas, it is difficult to monitor the temperature online
[0005] The advantage of the present invention is that the device adopts wireless communication technology to wirelessly transmit the temperature signal of the measured conductive part in the fully enclosed combined electrical appliance GIS, thereby solving the problem that the temperature of the measured conductive part cannot be monitored online in the fully enclosed combined electrical appliance GIS. It has the characteristics of simple, safe and accurate temperature monitoring process

Description

technical field [0001] The invention relates to a fully enclosed combined electric GIS wireless temperature on-line monitoring device, which belongs to the field of on-line monitoring of high-voltage electric appliances and power system parameters. Background technique [0002] Since the conductive parts such as various electrical overlapping points, contacts, and conductive bars in the existing fully enclosed combined electrical appliance GIS are all enclosed in the SF 6 In the gas, people cannot touch these conductive parts during operation, and the temperature signals of these conductive parts cannot be transmitted. The problem of temperature online monitoring in electrical appliance GIS, therefore, there is no discussion in the current literature on online monitoring of temperature parameters of conductive parts of fully enclosed combined electrical appliance GIS. Contents of the invention [0003] The purpose of the present invention is to provide a wireless temperat...
