Problems solved by technology

During the test, due to the high voltage bushing of the transformer, it is often necessary to use an aerial work vehicle in the process of disconnecting the wiring during the test, which consumes a lot of manpower, material resources and financial resources.
At the same time, due to the need for climbing operations, the safety risks of operations are also increased.

Abstract

Provided is a high-altitude test clamp for deformation of a transformer winding. The test clamp comprises a binding clip composed of an upper jaw and a lower jaw, an insulated operating rod arranged in the bottom of the binding clip and a lead rod arranged under the lower jaw. The high-altitude test clamp based on a frequency response method is provided with a special-purposed wiring clamp to connect and fix test wires, and the wiring clamp uses a BNC joint to ensure effective work of signal, input and shielding ends. The portable special-purposed insulated operating rod realizes wiring. The angle of the binding clip of the wiring clamp can be changed to complete wiring work of different angles, thicknesses and diameters of wiring positions, and high-altitude work is avoided.

Description

technical field [0001] The invention provides a transformer winding deformation high-altitude test clamp based on a frequency response method. Background technique [0002] The transformer winding constitutes the path of transformer electricity, and it is also a place where failures are more likely to occur. Since the transformer winding cannot be seen intuitively, a large amount of manpower, material resources, and financial resources are required for hoisting and inspection. At present, the frequency response method is generally used to analyze the deformation of the transformer winding. So as to judge the fault location and cause of the transformer winding. During the test, due to the high voltage bushing of the transformer, it is often necessary to use an aerial work vehicle in the process of disconnecting the wiring during the test, which consumes a lot of manpower, material resources and financial resources. At the same time, due to the need for climbing operations, t...
