Abstract

The utility model provides an annular insulation transformer which comprises an annular transformer body, insulation pads are arranged on both of the upper surface and the lower surface of the annular transformer body, an insulation plate is arranged on the insulation pad on the upper surface, the insulation plate, and the insulation pads and the annular transformer body are sleeved on a bolt and are fixed via a nut matched with the bolt. Since the insulation pads are arranged on both of the upper surface and the lower surface of the annular transformer body, the transformer is prevented from electric leakage to cause an accident; the insulation plate is arranged on the insulation pad on the upper surface and used for fixing the insulation pad, thus, the insulation pad is prevented from swinging, and better insulation effect is achieved; the annular insulation transformer has the advantages of simple structure, safety, reliability, good insulation effect and the like.

Description

Dead ring shape transformer

Technical field

The utility model belongs to transformer technology field, especially relates to a kind of dead ring shape transformer.

Background technology

Toroidal transformer is a large type of electronic transformer, has been widely used in the higher electronic equipment of home appliance and other specification requirement, and its main application is as power transformer and isolating transformer.Toroidal transformer is widely used in the aspects such as computer, Medical Devices, telecommunication, instrument and lighting, has the good ratio of performance to price, has good output characteristic and antijamming capability.Toroidal transformer insulation effect in existing technology is poor, and casualty accident easily occurs, dangerous reliable.

Summary of the invention

The purpose of this utility model be to provide a kind of simple in structure, insulation effect good and safe and reliable dead ring shape transformer.

The technical solution of the utility model is: dead ring shape transformer, comprise toroidal transformer body, the upper and lower surface of described toroidal transformer body is equipped with insulation cushion, the insulation cushion of described upper surface is provided with insulation board, described insulation board, insulation cushion and toroidal transformer body are set on bolt, and fix by the nut coordinating with bolt.

Further, described insulation cushion is rubber blanket.

Further, described insulation board is circular, and its radius is less than toroidal transformer body.

Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, in toroidal transformer upper and lower surface, be equipped with insulation cushion, prevent transformer electric leakage, cause the accident; On the insulation cushion of upper surface, be provided with insulation board, for fixed insulation pad, avoid its surrounding to swing, make insulation effect better; Have simple in structure, safe and reliable, the advantage such as insulation effect is good.

Embodiment

As shown in Figure 1, the technical solution of the utility model is: dead ring shape transformer, comprise toroidal transformer body 1, and the upper and lower surface of described toroidal transformer body 1 is equipped with insulation cushion 2, prevents transformer electric leakage, causes the accident; The insulation cushion 2 of described upper surface is provided with insulation board 3, for fixed insulation pad 2, avoid its surrounding to swing, described insulation board 3, insulation cushion 2 and toroidal transformer body 1 are set on bolt 4, and fixing by the nut 5 coordinating with bolt 4, make between insulation board 3, insulation cushion 2 and toroidal transformer body 1 closelyr, make insulation effect good.

In the present embodiment, described insulation cushion 2 is rubber blanket, and it is corrosion-resistant, antistatic, can cut into arbitrary shape, effectively prevents electric leakage; Described insulation board 3 is circular, and its radius is less than toroidal transformer body 1.

Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
