Description

A kind of compact switch transformer

Technical field

This utility model is related to technical field of electric equipment, specially a kind of compact switch transformer.

Background technology

Compact switch transformer generally refers to the transformator used by Switching Power Supply the inside, is operated in ten a few to tens of kilohertzs Hereby under the pulse condition of even hundreds of KHz frequency.It is temperature and humidity test that 85 degree of humidity is 85% that double 85 tests are exactly temperature, It is main to use and photovoltaic industry, and the indispensable test equipment of solar energy industry, for testing photovoltaic module, mainly monocrystal silicon group Part, ground Crystalline Silicon PV Module, ground carries out test with a series of photovoltaic module such as membrane photovoltaic component can be reproduced Destruction produced by environment, confirms that component can bear hot and humid negative temperature afterwards therewith and affect by double 85 tests, And for the fatigue and thermal failure that cause when temperature repeats and changes, it is otherwise determined that photovoltaic module exposes to the open air at high humidity and produces Thermal stress and the ability of dampness prolonged permeation can be resisted.

Compact switch transformer plays vital effect, existing compact switch transformer in double 85 tests Due to its insulating properties it is not strong, it is non-moistureproof, result in and there is certain potential safety hazard in an experiment.

Utility model content

The purpose of this utility model is to provide a kind of compact switch transformer, to solve above-mentioned background technology in propose Problem.

For achieving the above object, this utility model provides following technical scheme：A kind of compact switch transformer, including it is upper Housing, it is characterised in that：The bottom left and right sides of the upper shell is installed with side plate casing, and two side plate casings Bottom is fixedly connected by base, and NiCuZn ferrite nanos crystalline substance magnetic core is installed between the upper shell and base, and The outside winding of the NiCuZn ferrite nanos crystalline substance magnetic core is provided with winding coil, and the outside bread of the winding coil is wrapped with flange Adhesive tape, the base includes top board and base plate, is fixedly connected by support block between the top and base plate, and winding coil Bottom sequentially passes through base, and extends to the bottom of base and be connected with one end of binding post, and the winding coil is by a primary Coil, ancillary coil, two secondary coil compositions, the primary coils have centre cap；The upper shell and side plate Outer magnetic ring is enclosed with casing；The outer magnetic ring is by upper Fe-based amorphous alloy lamination and lower Fe-based amorphous alloy lamination snapping Into.

Preferably, the top board and base plate before and after both sides are equidistant offers five winding displacement grooves, the primary line The centre cap of circle and bottom, the bottom of ancillary coil, the bottom of secondary coil sequentially pass through the winding displacement groove on top board and base plate, And extend to the bottom of base plate to be connected with binding post.

Compared with prior art, the beneficial effects of the utility model are：The compact switch transformer simple structure, design Rationally, by being provided with side plate casing in the bottom of upper shell, the flange adhesive tape on winding coil top is increased, is improved compact The insulating properties and humidity resistance of type switch transformer, so as to improve safety of the compact switch transformer in experimentation Property, eliminate potential safety hazard of the compact switch transformer in double 85 experiments.
