Como medir a temperatura das juntas dos cabos na unidade principal em anel

Ring main unit is a commonly used switching unit in power supply systems, and its normal operation is an important guarantee for power supply safety and stability. The rapid deterioration and failure of insulation caused by partial discharge and local temperature overheating are common causes of faults in ring main units. Portanto, conducting partial discharge and temperature monitoring on ring main units is of great significance for evaluating their status and warning faults. No sistema de energia, temperature has always been a very important parameter, and the electrical contacts between numerous high-voltage electrical equipment themselves and high-voltage electrical equipment are the weakest link in power transmission. The fundamental problem is the heating of electrical contacts. À medida que o tempo de aumento da temperatura se prolonga, o grau de oxidação em temperaturas que excedem o limite aumentará devido ao aquecimento, which may cause major accidents such as burning the busbar and contacts, damaging the contacts, e queda de energia. Especially due to the exposed high voltage inside the switchgear, the space is enclosed and narrow, impossibilitando a realização de inspeção manual e medição de temperatura. Portanto, it is particularly important to use fluorescent fiber optic temperature sensing technology to monitor the temperature rise of high-voltage electrical contacts in real time.
