摘要：High-voltage insulators are one of the devices widely used in power systems, and their pros and cons are directly related to the safe and stable operation of the power system. The large-tonnage UHV insulator AC withstand voltage detection method is restricted by conditions at the engineering site, and the detection efficiency is low and difficult to implement. The research on the method of detecting UHV zero-value insulators using high-voltage pulses and the development of portable detection devices are of great significance. This article has completed the portable insulator detection device using a miniaturized high-voltage pulse test power supply. The developed portable UHV zero-value insulator detection device can effectively judge zero-value, low-value and high-value UHV insulators, and adapt to large quantities of UHV insulators. Requirements for efficient testing.
