Abstract
The utility model relates to a transformer which comprises a magnetic core body, wherein the magnetic core body comprises an external cut magnetic core layer and an internal un-cut magnetic core layer, and two gaps which are symmetric with respect to the center are formed in the cut magnetic core layer. The transformer has the beneficial effects that an un-cut magnetic core ensures operation under a normal working condition, but an un-cut magnetic core is saturated when certain special working conditions occur, the cut magnetic core plays a main role in supporting the applied voltage to ensure that the applied voltage does not pass overlarge current, and the current is limited in a safety level.
Description
Technical field
The utility model relates to a kind of transformer.
Background technology
The magnetic core of transformer is divided into cutting magnetic core and does not cut magnetic core, does not cut magnetic core and has higher magnetic permeability, and its requirement to electric current is lower, and cutting magnetic core can effectively prevent magnetic saturation, so fail safe is better.In prior art, the magnetic core of transformer mostly is a monolithic construction, most cutting magnetic cores are also the not cutting magnetic cores of some, because both respectively have pluses and minuses, therefore it respectively has pluses and minuses on using, but in prior art also not by above-mentioned both directly combine to make transformer.
Utility model content
The purpose of this utility model is to provide a kind of transformer, to overcome currently available technology above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
, comprising magnetic core body, described magnetic core body comprises outside cutting core layer and inner not cutting core layer, in described cutting core layer, about centrosymmetric, is provided with two gaps; In described gap, be provided with polyester film or polyester-imide film.
Further, the described width that does not cut core layer is greater than the width of cutting core layer.
Preferably, the width in described gap is 50 microns.
The beneficial effects of the utility model are: do not cut magnetic core and guarantee the operation under nominal situation, but while running into some special operation conditions, do not cut magnetic core saturated, cutting magnetic core generation Main Function, to support added voltage, make it not by excessive electric current, by current limit within the level of a safety.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of magnetic core body described in the utility model embodiment.
In figure:
1, cutting core layer; 2, do not cut core layer; 3, gap.
Embodiment
As shown in Figure 1, a kind of transformer described in the utility model embodiment, comprises magnetic core body, and described magnetic core body comprises outside cutting core layer 1 and inner not cutting core layer 2, in described cutting core layer 1, about centrosymmetric, is provided with two gaps 3.The described width that does not cut core layer 2 is greater than the width of cutting core layer 1.The width in described gap 3 is 50 microns.In described gap 3, be provided with polyester film or polyester-imide film.
A kind of transformer that the utility model provides, concentrating through being cut into uncut magnetic core the compound body being fitted together, concretely, be exactly not cut the inside that core layer 2 is enclosed within cutting core layer 1, under normal condition, do not cut magnetic core and work, under unusual situation, through the magnetic core of cutting, play a major role to prevent too high switch immediate current and to transistorized Latent destruction effect.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection range of the present utility model.
Claims (3)
