AC power frequency withstand voltage test equipment

1、 Function Description

The AC power frequency withstand voltage test equipment meets the requirements of the national standard DL/T848.2-2004 for test transformers. The product has the characteristics of small size, light weight, compact structure, complete functions, and easy use. It is a high-voltage testing instrument used in power, industrial and mining, scientific research and other departments to conduct power frequency withstand voltage tests and DC leakage tests on various high-voltage electrical equipment, electrical components, and insulation materials.

The AC power frequency withstand voltage test equipment adopts a same core cylindrical multi-layer tower structure, with the primary low-voltage winding wound on the iron core and the secondary high-voltage winding wound on the outside of the low-voltage winding. This coaxial arrangement reduces coupling losses between windings. The high-voltage silicon stack is packaged in a sleeve using a process, and the outer shell of the product is made into an octagonal structure that matches the core. The overall appearance is beautiful and elegant
