Development of a Ground Clamp for HV Cable Terminals in Central Withdrawable Metal-enclosed Switch-gear

FU Heng;HE Jianming;WU Yifei;State Grid Shaoxing Power Supply Company;  
In order to avoid accidents of personal electric shock caused by line switching,the HV Cable Terminals in Central Withdrawable Metal-enclosed Switchgear should always be grounded in operating the terminals. A ground clamp special for the HV Cable Terminals was developed in the paper. This clamp is in the form of a window. Its parallel-jaw is clamped by the use of lead screw pair. It can be assembled to the HV Cable Terminals without affecting the connection or disconnection of the terminals. Tightening force,contact resistance and temperature rise were chosen as the performance indices to evaluate the electrical and mechanical performances of the clamp. Simulation and measured value show that these performances meet the requirements.
