AI Technical Summary
Existing insulation withstand voltage testing equipment is bulky, costly, and unsuitable for testing small insulation components. Furthermore, suppliers' electrical performance testing is not rigorous enough, leading to substandard product quality.
A 252kV SF6 gas-insulated voltage transformer was used as the transformer, and a third-frequency harmonic device was used for the pressure test. An electromagnetic voltage transformer was used to control the voltage. A fully enclosed insulator and withstand voltage test structure was designed, including pads, grounding springs and test fixtures. The test was carried out by injecting SF6 gas through vacuum.
It enables efficient and accurate testing of the electrical performance of small insulating components. The equipment is small in size, has high voltage and low partial discharge, and is easy to assemble and disassemble. It can cover the electrical performance testing of insulating components below 500KV, thus improving testing efficiency.
