Problems solved by technology

[0002] When the amorphous alloy transformer is running, there will be scattered debris on the surface of the iron core. The debris will move to the winding with the circulating oil. When the transformer is running, the debris on the winding will discharge, causing the winding to be short-circuited, seriously affecting the quality of the amorphous transformer.

Abstract

The invention discloses an assembling method for a preservative oil immersion type amorphous transformer iron core. Before assembling of the amorphous iron core, the contact portion of the amorphous iron core and a coil is wrapped by cable paper, the column portion of the amorphous iron core is wrapped by noise reduction cable paper; the iron core is sleeved, after the end of an iron core lap joint is sealed, amorphous fragments on the surface are sucked away through a dust collector, glass cement is applied, and the upper and lower surfaces of the iron core are both stuck and covered throughnoise reduction cable paper. Compared with the prior art, the iron core fragment production probability during assembling is lowered, the iron core fragment flowing channel during transformer operation is blocked, and the probability that a short circuit happens due to fragment flowing is lowered, so that the quality of the transformer is ensured, and the service life of the transformer is prolonged.

Description

technical field [0001] The invention belongs to the technical field of power transformer manufacturing, and relates to an assembly method for a protective oil-immersed amorphous transformer core. Background technique [0002] When the amorphous alloy transformer is running, there will be scattered debris on the surface of the iron core. The debris will move to the winding with the circulating oil. When the transformer is running, the debris on the winding will discharge, causing the winding to be short-circuited, seriously affecting the quality of the amorphous transformer. How to effectively protect the oil-immersed amorphous transformer core and reduce the probability of amorphous core fragments is the technical problem to be solved by the present invention. Contents of the invention [0003] Purpose of the invention: Aiming at the problems existing in the prior art, the purpose of the present invention is to provide an assembly method for a protective oil-immersed amorp...
