Method for remotely detecting surface temperature of primary equipment of transformer substation

Abstract

A method for remotely detecting the surface temperature of primary equipment of a transformer substation comprises the steps of utilizing the heating effect of electrically charged equipment and utilizing electromagnet radiation detection collecting equipment to remotely detect the surface temperature of the primary equipment. The electromagnet radiation detection collecting equipment converts collected data into electric signals, the electric signals are processed into visible heat image video through combination of video monitoring. The heat image video visually displays the operation condition of the primary equipment. The electromagnet radiation detection collecting equipment detects periodically and in a 360-degree circulating mode in the transformer substation and the range of the whole station, and collects the largest temperature value in each angle range so as to form a multi-angle temperature trend tendency graph. The method can be used for remotely detecting the surface temperature of the primary equipment, detecting the primary equipment periodically in 24 hours of one day, and outputting the primary equipment temperature trend in the transformer substation. The method is free of manual operation, reduces the work intensity of inspection workers, avoids dangers caused by high-pressure environment operation to the inspection workers, reinforces the safety inspection of the transformer substation, and improves the operation level of the transformer substation.

Description

technical field [0001] The invention relates to a method for remotely detecting the surface temperature of primary equipment in a substation, and belongs to the technical field of smart grids. Background technique [0002] With the popularization and development of power system "smart grid" technology, the technical requirements for unattended substations are getting higher and higher. Remotely monitor the operation status of primary equipment in substations. In the construction of unattended substations, most of them are based on the "five remote" technologies such as telemetry, remote signaling, remote control, remote adjustment, and remote viewing. The "remote viewing" function is basically realized. Above all, visible light monitoring is mainly used for the purpose of placement and environmental monitoring, and the temperature and temperature distribution of equipment that can directly reflect the operation status of the power grid cannot be "remotely viewed". For the mo...

[0002] With the popularization and development of power system "smart grid" technology, the technical requirements for unattended substations are getting higher and higher. Remotely monitor the operation status of primary equipment in substations. In the construction of unattended substations, most of them are based on the "five remote" technologies such as telemetry, remote signaling, remote control, remote adjustment, and remote viewing. The "remote viewing" function is basically realized. Above all, visible light monitoring is mainly used for the purpose of placement and environmental monitoring, and the temperature and temperature distribution of equipment that can directly reflect the operation status of the power grid cannot be "remotely viewed". For the monitoring of the surface temperature of primary equipment, the current general monitoring The method is to manually use the far-infrared point-type thermometer to measure and collect temperature data on primary equipment or wire joints. This method cannot guarantee the safety of the substation and is prone to accidents. The other method uses temperature-sensing elements to tighten Paste the surface of the high-voltage object to be tested, send the temperature data through the wireless transmitter, and then use the wireless receiver to receive the collected temperature data. The defect of this method lies in the power supply of the temperature-sensing element, and the battery of the temperature-sensing element needs to be checked and replaced regularly. Working in a high-pressure environment has great potential safety hazards, and the transmission of wireless data in a high-voltage environment is subject to high-voltage interference, which cannot guarantee the stability of data transmission
