Partial discharge is a common physical phenomenon in the power system, which refers to the non-penetrating discharge of the air gap, oil film or conductor edge inside the insulation structure of high-voltage electrical equipment under the action of voltage. Although the energy of this discharge is small and does not cause damage to the equipment, it is an important symptom of equipment insulation deterioration. Therefore, it is very necessary and important to monitor the partial discharge in the power system.
By monitoring partial discharge, potential problems of equipment can be found in time, equipment failures can be prevented, operation reliability of equipment can be improved, and maintenance of equipment can be optimized to ensure the safe and stable operation of the power system. Therefore, strengthening the application of partial discharge monitoring technology can effectively improve the accuracy and reliability of monitoring, and provide a strong guarantee for the stable operation of the power system.
Shaanxi public has been deeply engaged in the field of smart grid monitoring and offline detection services for many years, adhered to independent innovation, focused on the research and development of partial discharge products, vigorously developed new technologies and developed new products, and successively launched intelligent Internet of Things off, fault location, mechanical characteristics, grounding circulation, temperature monitoring and other products, in the field of smart grid monitoring has formed a series of products and solutions with independent intellectual property rights for cables, GIS, switchgears, transformers and other high-voltage electrical equipment partial discharge monitoring systems. Our company's partial discharge monitoring system products use the method of partial discharge and temperature monitoring to grasp the insulation status of switchgear, cables and their internal high-voltage electrical equipment in real time, avoid the occurrence of serious accidents such as fire, provide a basis for evaluating their insulation level and aging degree, and help the safe construction and maintenance of high-voltage power equipment insulation operation.
