The two types of operation methods mainly comprise an insulating glove operation method. Generally, the surrounding of the working environment is flat and free of obstacles, an insulating arm car for hot-line work can enter a working area, and a common two-type insulating glove working method is generally adopted, and is simple and quick and is the largest working method in the current hot-line work business. However, when the surrounding environment is complicated and the insulating arm car cannot enter, the operation mode cannot be used, and an insulating rod operation method (ground potential) in the operation is needed to complete the operation.
Different from the traditional insulating glove operation mode which is carried out on an insulating bucket arm vehicle, the operation method of the insulating rod is a rod operation method, so that the operation difficulty is high, and the consumed time is long. Due to the operation difficulty, an ordinary ground potential ignition work needs to be close to 2 hours, the working efficiency is low, and the traditional insulating gloves can be ignited for 30 minutes in an electrified mode. Because of the special environment, some work can be completed only by one type of insulating rod operation method, and the method is irreplaceable. However, the insulating rod operation method needs to hold a relatively heavy operating rod for a long time, an operator often feels aching in arms after a few minutes, and even needs to change people to have a rest to complete work, and the operating rod can shake due to slight deficiency of force when the operator holds the operating rod for a long time, so that irrelevant equipment is not easily touched, and potential safety hazards are generated.
Therefore, it is highly desirable to provide a working solution for the insulation rod that is time-saving, labor-saving and safe.
