With the development of market economy, high-voltage XLPE insulated conductor, as a key component of urban transmission line, plays an important role in maintaining the safe and stable operation of urban high-voltage line. The completion acceptance test of high-voltage conductor is a defect test before the investment and operation of high-voltage cable lines. It is an important link to prevent the investment and risk operation of high-voltage cable line. Based on the actual application of acoustic imaging technology in the partial discharge test of high-voltage distribution equipment, this paper puts forward the detection algorithm of high-voltage electrical equipment, tests the traditional AC withstand voltage method and the number of defective lines and acceptance lines when acoustic imaging is applied to the partial discharge detection method of high-voltage electrical equipment. The test results show that after the acoustic imaging proposed in this paper is applied to the partial discharge detection technology of high-voltage electrical equipment, the defect detection rate in the complete acceptance test of high-voltage cable is improved, while the number of operating lines with faults caused by small defects is reduced, which effectively reduces the number of high-voltage cables with faults caused by hidden dangers. It is verified that the application of acoustic imaging in partial discharge detection of high-voltage electrical equipment can effectively improve the fault detection rate of high-voltage cable completion acceptance and reduce the hidden dangers of high-voltage cable belts. The application of acoustic imaging in partial discharge detection of high voltage electrical equipment is the general trend in the future.

“…According to CIGRE Working Group B3.37, the average occurrence rate of internal short-circuit (high-current) arc fault in switchgear is about 1.3 per 10,000 switchgear and year [2]. Although the occurrence rate is low, the number of switchgears is huge, so the arc fault is a security risk that cannot be ignored [3]. Since the tremendous energy release by arcing within a short period of time, it will produce dangerous effects such as over-pressure (explosive burst) and high temperature (thermal injuries or fire accidents), which may damage the enclosure, installation rooms, the build-ings, and even endanger personnel around [3][4][5][6][7].…”

The explosion accident due to the internal arc fault in the metal‐enclosed switchgear cannot be ignored. Therefore, improving the ability of switchgear to resist the arc fault has important significance. In this paper, a passive protection measure by installing the buffer volume (BV) was proposed. The short‐circuit arcing tests were carried out in the small‐scale switchgear compartments, and the pressure rise was measured in the different models. The changes of pressure rise before and after installing BV were analyzed. Then, the calculation methods of pressure rise in the compartments and the mechanical response of the enclosure were put forward. By calculating the distributions of the pressure rise and temperature rise in the compartments, as well as the time‐varying displacement and stress of the enclosure, the pressure relief effect of the BV has been discussed. Results show that after installing the BV, the pressure rise, displacement, and stress are all decreased obviously in the initial of arcing. Hence, the arc fault protection effect for the switchgear can be improved by properly installing the BV.
