Transformer body structure

Abstract

The invention relates to a transformer body structure, in particular to a body structure of an open type winding iron core transformer. The transformer body structure comprises a magnetic flux loop formed by splicing multiple silicon steel sheets, an upper clamping part arranged on the upper portion of the magnetic flux loop, a lower clamping part arranged on the lower portion of the magnetic flux loop and two side plates positioned on the left and right sides of the body structure, the upper clamping part comprises an upper body and upper fixed plates fixedly arranged on the left and right sides of the upper body, the lower clamping part comprises a lower body and lower fixed plates fixedly arranged on the left and right sides of the lower body, the side plates are detachable and connected with the upper fixed plates and the lower fixed plates respectively, a storage space of the magnetic flux loop is formed among the upper clamping part, the two side plates and the lower clamping part, and a connecting mechanism capable of being in detachable connection is arranged between the upper clamping part and the lower clamping part. The transformer body structure is compact in structure, high in strength, small in noise and high in short-circuit resistance.

Description

technical field [0001] The invention relates to a transformer body structure, in particular to a body structure of an open winding iron core transformer. Background technique [0002] Open-ended wound core transformers are widely used due to their advantages of low no-load loss and low noise. However, due to the particularity of the iron core structure, the windings in the prior art generally can only adopt a rectangular structure, and the body strength of the transformer is lower than that of a circular winding or an elliptical winding. However, the traditional four-frame clamp structure does not have a mechanism for axially compressing the body, so it cannot play the role of axially compressing the body. Although the channel-type clamp structure with the upper and lower screw rods can be compressed axially, it cannot control the winding deformation caused by the radial force when the transformer is short-circuited.

However, due to the particularity of the iron core structure, the windings in the prior art generally can only adopt a rectangular structure, and the body strength of the transformer is lower than that of a circular winding or an elliptical winding.

However, the traditional four-frame clamp structure does not have a mechanism for axially compressing the body, so it cannot play the role of axially compressing the body.

Although the channel-type clamp structure with the upper and lower screw rods can be compressed axially, it cannot control the winding deformation caused by the amplitude force when the transformer is short-circuited.
