The application provides a GIS external temperature measurement device, including a special temperature measurement unit; the special temperature measurement unit is arranged on the outer surface of the GIS; the special temperature measurement unit includes a platinum resistance carrier board module, an ADC acquisition module, a wind speed signal acquisition module, Single-chip signal conditioning module, signal processing terminal module and wireless transceiver circuit module; platinum resistor carrier board module and ADC acquisition module are used to collect and preliminarily calibrate the temperature data of the GIS shell; the wind speed signal acquisition module is used to collect the wind speed data of the GIS shell ; The wireless transceiver circuit module is in communication connection with the signal conditioning module of the single chip microcomputer, and is used to transmit all signal data of the signal conditioning module of the single chip microcomputer to the signal processing terminal module. This application solves the problems of low security, poor real-time performance, difficult wiring, and greater influence by environmental factors in the commonly used temperature measurement system at present, which makes it difficult for the current temperature measurement system to accurately measure the online temperature of GIS.
Description
technical field [0001] The application relates to the field of electrical measuring equipment, in particular to a GIS external temperature measuring equipment. Background technique [0002] With the rapid development of my country's electric power industry, the power load presents a surge trend, and the gas-insulated metal-enclosed switch (GIS), as the switchgear for switching power loads in the power system, its thermal failure rate is also increasing year by year. When the contacts of GIS equipment are in poor contact or the insulation is aging, the contact resistance of the GIS diversion part will increase and the discharge along the surface caused by insulation aging will further expand the thermal fault and threaten the safe operation of power equipment. Therefore, it is of great significance to realize the online temperature monitoring of GIS equipment for the safe and reliable operation of GIS. [0003] At present, the commonly used temperature measurement system has...
