Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of detection brackets, in particular to a bracket for transformer bushing production detection. Background Art
[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil, and magnetic core. In electrical equipment, a transformer is a device that uses electromagnetic mutual induction to transform voltage, current, and impedance. The transformer bushing is the main insulation device outside the transformer box. The lead wires of the transformer winding must pass through the insulating transformer bushing to insulate the lead wires from each other and from the transformer casing. It also serves to fix the lead wires. Ensuring the sealing of the transformer bushing is the key to achieving a long service life. Therefore, during the production of transformer bushings, the entire transformer bushing needs to be inspected to check for cracks and scratches that may affect the sealing performance of the transformer bushing.
[0003] When inspecting the inner wall of the bushing, a bracket needs to be installed on the outside of the inspection equipment to ensure stability during inspection. In the existing technology, the bracket does not have the function of adjusting the size during use and can only be used for pipes of fixed sizes. When inspecting pipes of different sizes, it is necessary to replace brackets of different sizes, which is inconvenient to use. For this reason, we provide a bracket for transformer bushing production inspection. Utility Model Content
