Abstract

The utility model discloses a kind of built-in graphene self- recoverage insurance electronic transformers, including transformer body (1), and it is set to the output winding (2) on transformer body (1) and input winding (3), the transformer body (1) is internally provided with transformer wire packet (4), an insurance (5) is installed in any position of the input winding (3) of the transformer body (1), which is graphene insurance.The utility model is insured using graphene self- recoverage, is effectively controlled product quality, is allowed product in abnormal cases can be with self-protection, the route used product reality is also to have very much protective effect.

Description

A kind of built-in graphene self- recoverage insurance electronic transformer

Technical field

The utility model relates to a kind of transformers, and in particular to a kind of built-in graphene self- recoverage insurance electronic transformer.

Background technique

Current is only on the market PTC ceramics insurance and Temperature protection two built in product in the embedded with safety transformer used Major class, the insurance generated effect under route abnormal conditions are that ceramic PTC insurance is only that high resistant is under abnormal conditions State, Temperature protection are disposably to protect；

1. the shortcomings that prior art, is as follows:

A. if when using ceramic PTC, if there is exception in route or exception occurs in product itself, ceramics PTC enters high-impedance state, and high-impedance state makes electronics be difficult to move, so that circuit is protected, but this abnormal maximum drawback is, it is high The ceramic PTC of resistance state body temperature in the case where not releasing voltage is increased in aggregation, transformer in prolonged situation It will appear 2 exceptions for example, blowing, black, burn.

B. if asking transformer under money to be waited when abnormal using Temperature protection, it is irrecoverable that insurance, which is disposable, Product, this can be greatly inconvenient when product is with changing.

C. if being temperature conduction using maximum drawback when temperature controller due to temperature controller, miniature electric transformer is in mesh Before be to be difficult with.

Summary of the invention

The technical problem to be solved by the utility model is to provide a kind of built-in graphene self- recoverage insurance electronic transformer, Effectively be utilized that graphene insurance has in itself can breakaway-element protection, route occur when abnormal conditions manufactuerer's output insurance into Enter action state, back-end circuit is effectively protected.

The utility model is achieved through the following technical solutions: a kind of built-in graphene self- recoverage insurance electronic transformation Device, including transformer body, and the output winding and input winding that are set on transformer body, the transformer body Be internally provided with transformer wire packet, an insurance, the insurance are installed in any position of the input winding of the transformer body For graphene insurance.

The insurance is installed on inside the line packet of transformer as a preferred technical solution,.

The insurance is installed on transformer body as a preferred technical solution,.

The beneficial effects of the utility model are: graphene built in the utility model insures transformer, which goes out Existing electric current, voltage, transformer can enter off-state under any abnormal conditions of temperature.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, it is also possible to obtain other drawings based on these drawings.

Fig. 1 is the structural schematic diagram of the insurance of the utility model；

Fig. 2 is the scheme of installation under the insurance built-in state of the utility model；

Fig. 3 is the scheme of installation under the external state of insurance of the utility model；

Fig. 4 is the working principle diagram of the utility model.

Specific embodiment

All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive Feature and/or step other than, can combine in any way.

Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only It is an example in a series of equivalent or similar characteristics.

As shown in Figure 1 and Figure 4, including transformer body 1, and the output winding 2 that is set on transformer body 1 and Winding 3 is inputted, the transformer body 1 is internally provided with transformer wire packet 4, the input winding 3 of the transformer body 1 An insurance 5 is installed in any position, which is graphene insurance.Since insurance is that graphene self- recoverage insures, there is electricity Stream, voltage, temperature, overload, any situation occur can protect extremely.

As shown in Fig. 2, the insurance 5 is installed on inside the line packet 4 of transformer, or as shown in figure 3, insurance 5 is installed on On transformer body 1.

The beneficial effects of the utility model are: graphene built in the utility model insures transformer, which goes out Existing electric current, voltage, transformer can enter off-state under any abnormal conditions of temperature.

Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to In this, any change or replacement expected without creative work be should be covered within the scope of the utility model. Therefore, the protection scope of the utility model should be determined by the scope of protection defined in the claims.
