Description
Technical field
The utility model relates to electronic device field, relates in particular to a kind of transformer.
Background technology
Transformer is called again instrument transformer, is the general designation of current transformer and voltage transformer. Can be by heightVoltage becomes low-voltage, large electric current becomes little electric current, for measuring or protection system. Its function is mainlyBy high voltage or large electric current scaling transformation become standard low-voltage (100V) or the little electric current of standard (5A or1A, all refers to rated value), so as to realize measuring instrument, protection equipment and automatic control equipment standardization,Miniaturization. Transformer also can be used to separate high-voltage system simultaneously, to ensure the safety of the person and equipment.
Utility model content
The purpose of this utility model is to provide a kind of current transformer of back connection, solves above technologyProblem.
The technical problem that the utility model solves can realize by the following technical solutions:
The current transformer of back connection, comprises a current transformer housing, described current transformer housingInside be provided with iron core and be wrapped in the coil on iron core, it is characterized in that, described inductor housing bottom is provided withOne equipment input, described inductor housing back is provided with an equipment output end;
The both sides of the edge of described inductor housing are equipped with a projection, and the height of described projection exists20mm～30mm。
The utility model, by back cabling, can reduce the operation of wiring, and the utility model passes throughCabling is entered to output from behind from bottom, can reduce in appearance arranging of line, do not affect the appearance.The utility model, by projection, can make transformer in use produce creep age distance, can increaseDielectric strength, prevents electric leakage.
Described current transformer housing is the current transformer housing being formed by poured with epoxy resin.
The housing that the utility model forms by use poured with epoxy resin uses comparatively durable, service lifeLong.
On described iron core, winding around forms a coil layer, is also wound around a cooling tube and forms one on described iron coreCooling tube layer, described coil layer and described cooling tube layer are alternately arranged.
The utility model is alternately arranged and can be reduced the volume of transformer by coil layer and described cooling tube layer,Improve cooling effect.
Described cooling tube is the cooling tube of a flat belt-like.

Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to brightWhite understanding, further sets forth the utility model below in conjunction with concrete diagram.
With reference to Fig. 1, the current transformer of back connection, comprises a current transformer housing 1, Current Mutual InductanceIn device housing, be provided with iron core and be wrapped in the coil on iron core, inductor housing bottom is provided with an equipment inputEnd, inductor housing back is provided with an equipment output end; The both sides of the edge of inductor housing are equipped with one and dash forwardPlay 2, the height of projection is at 20mm～30mm. The utility model, by back cabling, can reduce wiringOperation, and the utility model is by entering cabling from behind output from bottom, can be in appearanceReduce arranging of line, do not affect the appearance. The utility model, by projection, can make transformer useIn journey, produce creep age distance, can increase dielectric strength, prevent electric leakage.
Current transformer housing is the current transformer housing being formed by poured with epoxy resin. The utility modelComparatively durable by the housing use that uses poured with epoxy resin to form, long service life. On iron core, be wound aroundCoil forms a coil layer, is also wound around a cooling tube and forms a cooling tube layer, coil layer and cooling on iron corePipe layer is alternately arranged. The utility model is alternately arranged and can be reduced transformer by coil layer and cooling tube layerVolume, improves cooling effect. Cooling tube is the cooling tube of a flat belt-like. The utility model is by limitingThe shape of cooling tube, can reduce volume as far as possible. Iron core is a hollow circulus, hollow ringIn shape structure, four angles in outside are equipped with transition arc. The utility model passes through employing nothing cutting end faceIron core, is evenly distributed iron core surrounding magnetic field, and the leakage field of transformer is minimum.
More than show and described general principle of the present utility model and principal character and of the present utility model excellentPoint. The technical staff of the industry should understand, and the utility model is not restricted to the described embodiments, above-mentionedThat in embodiment and description, describes just illustrates principle of the present utility model, is not departing from the utility modelUnder the prerequisite of spirit and scope, the utility model also has various changes and modifications, these changes and improvementsAll fall within the scope of claimed the utility model. The claimed scope of the utility model is by appended powerProfit claim and equivalent thereof define.
