Clamp insulating structure of dry-type transformer

Abstract

The invention discloses a clamp insulating structure of a dry-type transformer. The structure comprises clamp insulating parts, an upper clamp and a lower clamp, wherein the clamp insulating parts are arranged on the upper clamp and the lower clamp. Each clamp insulating part comprises a web plate, a support plate and buffer pads, wherein the buffer pads and the support plate are of parallelogram structures which are matched, the buffer pads adhere to the support plate, the set of buffer pads and the support plate adhere to the web plate in a spaced mode, and the web plate is fixed to the upper clamp and the lower clamp. Due to the fact that a heat radiation air channel is formed between the upper clamp and an iron core, heat in an original heat accumulation area is effectively released, and temperature rise of the transformer is reduced. A convection air channel between the lower clamp and the iron core enables air to enter the low portion of a coil smoothly, so that air convection is formed effectively and heat dissipation of the coil is guaranteed. The buffer pads and the support plates are small, and therefore sufficient utilization of materials is facilitated and raw materials are saved greatly.

Description

technical field [0001] The invention belongs to the field of transformer manufacturing and relates to a clip insulation structure of a dry-type transformer. Background technique [0002] The function of transformer clip insulation is the insulation between the iron core and the upper and lower clips to ensure that the iron core is grounded at one point. The clip insulation of the dry-type transformer also plays the role of sound absorption and noise reduction.

AI Technical Summary

Problems solved by technology

The disadvantage is that when the transformer is running, the heat generated by the coil goes up, forming a heat accumulation area between the lower side of the upper clamp and the iron core, and there is no gap between the clamp and the iron core, so the heat is difficult to dissipate

There is no gap between the lower clamp and the iron core, so sufficient air cannot enter from the lower part of the iron core, which further affects the heat dissipation effect of the transformer
