Research on suspended remote-control high-voltage test discharge grounding device

Abstract

When conducting high-voltage test projects such as lightning impulse, operating wave, alternating current (AC) withstand voltage, and direct current (DC) withstand voltage on power equipment such as transformers and power cables, manual repeated discharge is required before and after the test project in order to avoid the interaction between operating wave and residual charge from puncturing the equipment. The discharge time is longer when it comes to electrical equipment with large capacitance. Currently, the safety of grounding devices in domestic power systems is poor, and the operation process is cumbersome, making it difficult for the grounding device to become intelligent. Therefore, a suspended remote-control high-voltage test discharge grounding device with good voltage equalization effect, strong anti-interference ability, and the ability to achieve long-distance, non-contact discharge operation is developed, Through a large number of field practical applications, the device ensures that the field test takes effective safety measures in time, protects the safety of test personnel and test equipment, improves the efficiency of full discharge of test equipment, and greatly reduces the voltage test discharge time of large capacity equipment.
