Research and Application of Quick Connection Protection Device for 10 kV Cable Terminal
A 10 kV cable terminal quick connection protection device is designed to provide insulation protection for the ca-ble terminal through bolted connection. Based on the device,a new method for outage quick recovery of 10 kV cable ter-minal direct connection is proposed. When a power supply point loses power,the method in this paper can solve the prob-lem of sluggish power cable repair work,and reduce average power recovery time by more than 85%. The safety of the device and the effectiveness of the operation method are verified by a pilot installation at a 10 kV switch station in Lin'gang area of Shanghai.
