Substation capacitor temperature measuring and early warning system and method

Abstract

The invention relates to a substation capacitor temperature measuring and early warning system and method, and solves a problem that the temperature measuring equipment in the prior art cannot performcontinuous monitoring for a long time, high in cost, easy to be disturbed and unable to detect the temperature at a specific direction in a capacitor. The system comprises a temperature detection terminal, a transfer terminal and a client, wherein the temperature detection terminal comprises a plurality of wireless temperature measuring units and a plurality of internal wireless temperature measuring units, the client comprises a structure management unit, a comparison processing unit and an early warning unit, the surface wireless temperature measuring units and the internal wireless temperature measuring units are wirelessly connected with a transfer unit, the transfer unit is connected with the comparison processing unit of the client, and the structure management unit and the early warning unit are connected with the comparison processing unit. According to the invention, a wireless communication technology is combined, and the temperature detection terminal does not need line arrangement, thereby being more convenient for field installation. The substation capacitor temperature measuring and early warning system can detect a temperature abnormal condition timely and gives anearly warning in time. In addition, the substation capacitor temperature measuring and early warning system can accurately detect a temperature anomaly area of the capacitor.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a substation capacitor temperature measurement and early warning system and method. 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 test results are affected by se...
