Adjustable oil-immersed transformer coil restraining device

Abstract

The invention discloses an adjustable oil-immersed transformer coil restraining device which comprises a winding iron core, a winding operation table is connected to the bottom of the winding iron core in a clamped mode, a winding rotating table is rotatably connected to the interior of the winding operation table, and a winding motor is fixedly connected to the bottom of the winding rotating table. The outer surface of the winding motor is sleeved with a lifting hydraulic cylinder, the top of the lifting hydraulic cylinder is slidably connected with a resistance adjusting rod, and the top of the winding operation table is fixedly connected with a winding constraint lifting table. When a wire is wound on the outer surface of the winding iron core, the winding iron core can be placed on the top of the winding rotating table, then the winding rotating table is driven by the winding motor to start to rotate, and therefore the winding iron core is driven to start to rotate, and when the rotating force is too large, the resistance adjusting rod can be controlled by the lifting hydraulic cylinder to ascend and descend; and the rotating force of the winding rotating table is controlled, and the effect of conveniently adjusting the wire winding force is achieved.

Description

technical field [0001] The invention relates to the technical field of oil-immersed transformer coils, in particular to an adjustable restraint device for oil-immersed transformer coils. Background technique [0002] A transformer is a static electrical device used to convert AC voltage and current to transmit AC power. It realizes power transfer based on the principle of electromagnetic induction. Transformers can be divided into power transformers, test transformers, instrument transformers and Special-purpose transformers: power transformers are necessary equipment for power transmission and distribution, and power distribution for power users; test transformers are equipment for withstand voltage tests on electrical equipment; during production and processing of transformers, the windings need to be wound. Use the coil restraint device to constrain its winding. [0003] The winding form of the traditional oil-immersed transformer is: the iron core is stabilized on the r...

Problems solved by technology

[0003]The traditional oil-immersed transformer winding form is: the iron core is stabilized on the rotating roller and the wire is wound on the outer surface of the iron core by rolling, but the wire During the winding process, the traditional rotating roller cannot adjust the winding strength of the wire, and it is easy to cause the wire to break due to excessive force during the winding process.

[0004] For this reason, an adjustable oil-immersed transformer coil restraint device is proposed to solve the above-mentioned problem that the existing oil-immersed transformer cannot be wound. Adjust the winding force during the coil winding process, which is prone to breakage
