During the live operation of 10kV overhead distribution lines, in order to protect the safety of workers, it is necessary to insulate the accessible live equipment. Insulation treatment includes wrapping live equipment with insulating blankets or blocking live equipment with insulating partitions to limit the movement space of workers. The existing insulating partitions are fixed on the cross arm by means of bolts. Since the existing insulating partitions need to be manually disassembled and assembled, the operators need to wear insulating gloves directly between the cross arms, poles and live equipment. Therefore, in order to prevent the cross arm, pole and live equipment from forming a path through the human body, causing a short circuit between the human body and the electric shock, it is necessary to insulate and shield the live equipment and grounding body that may be touched before disassembling the pin. , so it takes a lot of work time. At the same time, because the insulating gloves are worn with three layers of gloves, the space between the fingers and the gloves is extremely thick, and it is extremely difficult to install the pins from the narrow gap of the insulating partition, which also results in time-consuming disassembly of the insulating partition. In addition, because the bolt is made of metal, there are potential safety hazards in live work. Therefore, there is an urgent need for a new type of insulating partition to improve the problems of difficult disassembly and low safety of the original insulating partition.
