transformer

Abstract

The invention discloses a transformer, which comprises a transformer body, the bottom side of the transformer body is provided with a mounting seat, and the top side of the mounting seat is provided with a mounting groove, and the transformer body is movably installed in the mounting groove; the two sides of the transformer body There are card slots on both sides, and slide slots are opened on the inner walls of both sides of the installation slot, and a block is slidably installed in the slide slot. One end of the block extends into the slot, and the other end is fixedly installed with a pull rod; The inner wall is provided with a placement groove, the placement groove is provided with a fixing groove, and a fixing rod is fixedly installed on the inner wall of the fixing groove. The invention is convenient for fast installation of the transformer, and can provide all-round multiple protection for the coil winding of the transformer; in addition, polyester resin is used for bonding between the insulating papers, thereby avoiding delamination caused by air bubbles between the insulating papers The production can improve its mechanical and electrical properties and ensure the stability and reliability of the transformer.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to a transformer. Background technique [0002] A transformer is a device that transforms AC voltage, current and impedance. The transformer is composed of a magnetic core, a skeleton and a coil winding. The coil winding has two or more windings. The winding and the magnetic core are collectively called the power transformer body. Electrical circuit part. [0003] In the existing transformers, various insulating materials are used to protect the coils to prevent leakage and short circuit, but the types of insulating materials currently used are single in structure, and cannot protect the coil windings in all directions, and the insulation performance is not ideal. Secondly, the existing Most of the insulating materials are made of multi-layer cardboard with a thickness of 9-200mm, and the cardboard is usually bonded together with phenolic adhesive paper, which often contains...

Problems solved by technology

[0003] In the existing transformers, various insulating materials are used to protect the coils to prevent leakage and short circuit. However, the types of insulating materials currently used are single in structure and cannot protect the coil windings in all directions. The insulation performance is not ideal. Secondly, the existing Most of the insulating materials are made of multi-layer cardboard with a thickness of 9-200mm, and the cardboard is usually bonded together with phenolic adhesive paper, which often contains air bubbles between the cardboards, resulting in initial partial discharge. Phenomena such as depression and easy delamination further lead to poor overall mechanical properties of cardboard

[0004] At the same time, the existing transformer needs to use various tools when installing it, which is not convenient for quick installation of the transformer, which is laborious and laborious, and cannot meet the needs of users
