Transformer coil winding and winding device including transformer coil winding

Abstract

A transformer coil winding, the transformer coil winding includes a coil and a spacer; the coil includes a first coil and a second coil, and the first coil and the second coil are respectively wound on both sides of the spacer The wire is wound; the spacer is provided with a slot, and the wire passes through the slot along a direction perpendicular to the spacer, and the slot is used to divide the wire into a first part and a second part. Two parts; a first part of the wire is wound on a first side of the spacer to form the first coil and a second part of the wire is wound on a second side of the spacer to form the second coil. The transformer coil winding of the present application can prevent the coil from collapsing and loosening, and keep the external dimensions of the coil consistent, which facilitates production and installation of the coil, saves insulating materials, and avoids a high-voltage short circuit between the coil and the magnetic core. The present application also provides a winding device including a transformer coil winding.

Description

technical field [0001] The invention relates to a transformer coil winding and a winding device comprising the transformer coil winding. Background technique [0002] In a transformer, the wire is usually wound in a double-layer pie shape with self-adhesive insulated wire to form a coil. However, after a single coil is installed in the window space of the magnetic core, the inner or outer wall of the coil will inevitably touch the center column or side column of the magnetic core, and during the working vibration of the transformer, the inner wall or the outer wall of the coil will inevitably touch the center column or side column of the magnetic core Or the side column for high-frequency friction. The short-circuit failure rate of the coil and the magnetic core will also increase sharply with the increase of the working time of the transformer. In addition, under high-voltage conditions, the place where the potential difference of the entire transformer is the largest, th...

Problems solved by technology

The short-circuit failure rate of the coil and the magnetic core will also increase sharply with the increase of the working time of the transformer

In addition, under high-voltage conditions, the place where the potential difference of the entire transformer is the largest, that is, between the coil starting wire and the tail wire, is prone to high-voltage breakdown of the transformer, which in turn leads to transformer failure and burning.

However, in the current coil design and practical application, there is no effective means to prevent the above problems
