The narrow cabinet high-voltage grounding switch product is the core safety structural product of the high-voltage complete switchgear. It ensures that the residual electrical energy that may be generated by the load can cause personal injury when it is in working condition; it has to withstand the influence of electrical and thermal stresses of the main circuit when it is not in working condition, as well as to ensure that the equipment and the load are not subjected to secondary damage when it is in fault condition. In the process of operation, it should not only ensure accurate positioning, but also ensure the smooth operation of the mechanical mechanism; it should be able to safely withstand the impact of the electrical energy that may be generated at the load side, but also ensure the safe isolation of the main circuit electrical energy from the load circuit. Finally, in the manual operation state, it should be light and labor-saving.

R&D product introduction: High-voltage grounding switch product is the core safety structural product of high-voltage complete switchgear. It ensures that the residual electrical energy that may be generated by the load can harm the person when it is in working condition; When it is not in working condition, it has to withstand the influence of electrical and thermal stresses of the main circuit, as well as to ensure that the equipment and loads are not subjected to secondary damage when in fault condition. Products in the R & D design, need to be applied to indoor 3-24KV three-phase AC 50 (60) HZ power system and various models of high-voltage switchgear supporting the use of high-voltage electrical equipment can also be used as a high-voltage electrical equipment maintenance system grounding role. The production standard of the product should be in line with GB1985-2004 "AC High Voltage Disconnectors and Grounding Switches" and IEC6227-102-2002 standard.

After three months of process, Sheng Zhongyi Electric Power Technology Co., Ltd. trial production of 12KV grounding switch samples delivered into the West Higher Institute testing center. After understanding that, in addition to the regular frequency withstand voltage, short-time withstand current, circuit resistance and mechanical test, the grounding switch products also need to accept the lightning impact and shutdown test two heavyweight experimental requirements. Through the continuous efforts of the technical team, in September 2012, our company successfully completed the testing task.
