Problems solved by technology

Due to the influence of unfavorable factors such as the weight of the grounding wire itself, the height of the installation point of the grounding wire, and the installation environment, there are high requirements for the physical strength and endurance of the operation and maintenance personnel during the installation of the grounding wire. When the installation of multiple sets of grounding wires is required, the operation and maintenance personnel may fail to install the grounding wires due to physical exhaustion, or even accidentally drop the grounding wires and wire clips and damage the equipment.

Abstract

Ground wire auxiliary installation device and ground wire installation method of substation. Installation of grounding wire before power outage and maintenance of equipment with voltage less than 500kV is always a problem puzzling operation and maintenance personnel. Due to the weight of the grounding wire, the height of the grounding wire installation point and the bad environment, there are high requirements for the physical strength and endurance of the operation and maintenance personnel in the process of the grounding wire installation. A lifting head is threadably connected with that insulate transfer rod (2), A low end of that insulated transfer rod is connected with the counterweight 3, a winding and unwinding device (4) is arranged on the insualted transfer rod; The insulated lifting rope (1) emitted from the winding and unwinding device is connected with the lifting rope fixing point (16) on the lifting head through a fixed pulley (17) on the lifting head, the lifting head comprises a lifting arm (6) and a lifting fixing fixture (5), and the lifting arm and the lifting fixing fixture are connected with each other through an axle pin. The invention is applied to the installation of the ground wire.

Description

Technical field: [0001] The invention relates to an auxiliary installation device for a grounding wire of a substation and a grounding wire installation method. Background technique: [0002] The installation of the grounding wire for equipment with voltage levels below 500 kV before power outage maintenance has always been a problem for operation and maintenance personnel. Due to the influence of unfavorable factors such as the weight of the grounding wire, the height of the grounding wire installation point, and the installation environment, the physical strength and endurance of the operation and maintenance personnel are very high during the installation of the grounding wire, especially when the maintenance work ticket includes When multiple sets of grounding wires are required for installation, operation and maintenance personnel are likely to fail the grounding wire installation due to physical exhaustion, or even accidentally drop the grounding wires and clamps and damage...
