Problems solved by technology

[0005] The present invention mainly solves the problem that in the prior art, the temperature in a closed environment cannot be tested by using an infrared imager for heating and repairing capacitors, and the test results are affected by seasons, time of day and the surface finish of the test equipment. The infrared test equipment is expensive and cannot be used continuously for a long time. To monitor the temperature of high-voltage electrical equipment, provide an automatic temperature measurement and early warning device for substation capacitors and its method to ensure real-time and accurate monitoring of the temperature of substation capacitors

Embodiment Construction

[0037] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0038] This embodiment is an automatic temperature measurement and early warning device for substation capacitors, such as figure 1 As shown, it is mainly composed of a wireless temperature measurement sensor 1, a sensor data acquisition device 2, a data management machine 3, and a client terminal 4. The wireless temperature measurement sensor 1 includes a temperature sensor 101 and a wireless temperature measurement terminal 102. The temperature sensor 101 is used to detect the surface temperature of the capacitor under test and transmit temperature information to the wireless temperature measurement terminal 102 in real time.

[0039] The sensor data collection device 2 is wirelessly connected to the wireless temperature measurement terminal 102 for collecting temperature information of the wireless temperature measurement terminal 102 and sen...

Abstract

The invention relates to a substation capacitor automatic temperature measurement and early warning device and its method, which mainly solves the problem that in the prior art, infrared imagers cannot be used to test the temperature in a closed environment for heating and maintenance of capacitors, and the test results are affected by the season, time and the surface of the test equipment. Influenced by smoothness, infrared testing equipment is expensive, and the temperature of high-voltage electrical equipment cannot be continuously monitored for a long time. An automatic temperature measurement and early warning device and method for substation capacitors are provided to ensure real-time and accurate monitoring of substation capacitor temperature.

Description

technical field [0001] The invention relates to the field of electric power equipment, in particular to an automatic temperature measurement and early warning device for substation capacitors and a method thereof. Background technique [0002] Various faults often occur in capacitors during operation, which pose a great threat to the safe and normal operation of the power system. The more common faults of capacitors in power operation include oil leakage, poor insulation, and burnt fuses. Among them, the most harmful and frequent faults are capacitor faults caused by heat. The heating of capacitor failure caused by heating can be further divided into heating at the connection point of the busbar and heating of the fuse outside the capacitor, and the latter is more likely to occur. [0003] At present, the heating and maintenance of capacitors are mainly inspected by infrared imagers, but infrared thermal images cannot test the temperature in a closed environment, and the te...
