Description

Technical Field

[0001] The utility model relates to the technical field of electric operating rods, in particular to a multifunctional high-altitude test wiring device. Background Art

[0002] After searching the existing Chinese patent document with the announcement number CN209233341U, an electrical test high-altitude wiring auxiliary pole is disclosed, including a handle, a retractable insulating pole, a handle, a gate wire, a retractable steel wire, a reset spring, a connecting rod, a movable baffle, a fixed baffle and a support seat; the device has a simple structure and easy operation through the electrical test high-altitude wiring auxiliary pole, and can perform high-altitude test wiring on the ground, effectively reducing the labor intensity of electrical testing and reducing the safety hazards of high-altitude operations; a retractable insulating pole is used, and the length can be adjusted telescopically to adapt to the ground height of different electrical equipment in the substation. At the same time, the horizontal hole in the electrical test high-altitude wiring auxiliary pole enables the test wire clamp to be placed horizontally, and the vertical hole enables the test wire clamp to be placed vertically, which adapts to the terminal board styles of various electrical equipment in the station; when the gate wire in the electrical test high-altitude wiring auxiliary pole of the utility model is curled, the steel wire rope therein has the same telescopic performance.

[0003] Equipment in power systems requires regular or irregular electrical testing to check its insulation performance and operating status to ensure safe and stable operation. Testing equipment such as transformers and circuit breakers requires personnel to work at height, posing a significant risk due to the height of the equipment. Especially during DC resistance testing of 220kV transformers, the vertical distance between the bushing top terminal and the transformer can be as high as 5 meters. Climbing the bushing to connect the wiring poses a significant risk, necessitating the use of an aerial platform vehicle. This not only reduces work efficiency but also increases operational risk. Therefore, when conducting electrical testing on high-placed equipment, it is essential to use aerial wiring tools to assist with wiring. Traditional aerial wiring pole clamps are fixed with a fixed top and bottom opening, unable to adjust the angle. They can only be clamped vertically onto horizontal guide rods or terminal clamps. They are not suitable for vertical clamps or guide rods. For example, in tests such as transformer DC resistance testing and winding deformation testing, the clamps must be clamped horizontally onto the vertical bushing top terminal clamp or guide rod. Furthermore, the clamping force of traditional aerial wiring clamps is weak, making them incapable of removing oxide layers on the equipment, resulting in high contact resistance and inaccurate test results.
