Description

technical field

[0001] The invention relates to live maintenance equipment for a power distribution network, in particular to an insulating baffle for live replacement of a lightning arrester on a switch cross arm with easy operation. Background technique

[0002] Due to the need for lightning protection, lightning arrester groups are generally installed on the crossarm of the user incoming switch of the distribution network, and regular replacement of lightning protection equipment and maintenance after failure are also a routine item in the daily live maintenance of the distribution network. In the method of direct operation with insulated bucket arm truck and insulated gloves, two people cooperate to operate with insulating cloth, jumper tube, and insulating locking rod. First, use insulating cloth to insulate and shield the insufficient distance between ground and phase. Then remove the pile head lead wire on the arrester, and fix it with a locking rod after removal. Du...
