3)分别从三组分流线组件5两端向三相高压线2中的上线、中线、下线引出三对软高压线56,软高压线的端部由分流线夹57与对应高压线2相连接,分流线横担固定架4上最靠近电杆1的分流线组件5对应连接上线高压线,分流线横担固定架4上最远离电杆1的分流线组件5对应连接下线高压线,分流线横担固定架上位置居中的分流线组件5对应连接中线高压线。该配置实现了绝缘杆作业法完成带负荷更换柱上开关时的分流目的,减少了遮蔽作业量,显著减少了停电范围和时间。3) Lead three pairs of soft high-voltage wires 56 from both ends of the three-group shunt line assembly 5 to the upper, middle, and lower wires of the three-phase high-voltage wires 2. The ends of the soft high-voltage wires are connected to the corresponding high-voltage wires 2 by shunt clamps 57 , the shunt line component 5 closest to the pole 1 on the shunt line cross arm fixing frame 4 is connected to the upper high-voltage line, and the shunt line component 5 farthest from the pole 1 on the shunt line cross arm fixing frame 4 is connected to the down line. For high-voltage lines, the shunt line assembly 5 located in the center on the shunt line cross-arm fixed frame is connected to the center line high-voltage line. This configuration realizes the diversion purpose when replacing the switch on the column under load using the insulating rod operation method, reduces the amount of shielding work, and significantly reduces the scope and time of the power outage.

The current carrying capacity of the shunt line assembly 5 meets the operating requirements and has sufficient mechanical strength. The gun operating rod can be used to hook the operating ring. The operating mechanism is screwed in a simple way, with a simple structure and easy operation. It can save 30% of the working time, improve the work efficiency, ensure the safety of the operation, and have low labor intensity; it can be disassembled and assembled for various working sites, with strong versatility and applicability.
