Abstract
The utility model aims to provide a built-in type voltage transformer which comprises an outer shell, a primary terminal, a primary coil and an iron core, wherein the primary terminal, the primary coil and the iron core are arranged inside the outer shell, and the iron core is in a rectangular shape. The primary coil is divided into two parts to be wound on one edge of the iron core, the primary coil and the iron core are arranged in parallel, the primary terminal is arranged on the outer shell, and a position of the outer shell, corresponding to the primary coil, is provided with a protrusion. The built-in type voltage transformer has the advantages of being compact in structure and effectively reducing size space.
Description
Technical field
The utility model relates to the measuring instrument field of instrumentation technology, relates in particular to a kind of built-in voltage transformer.
Background technology
Voltage transformer is a transformer that band is unshakable in one's determination.It mainly is comprised of first and second coil, iron core and insulation.When a winding applies a voltage U 1, in iron core, just produce a magnetic flux φ, according to the law of electromagnetic induction, then in secondary winding, just produce a secondary voltage U2.Change once or the number of turn of secondary winding, can produce different primary voltages and secondary voltage ratio, this just can form not voltage transformer on year-on-year basis.
In the prior art, be installed on the voltage transformer in the gas-filling cabinet, belong to built-in voltage transformer, the internal structure of existing built-in instrument transformer is generally from the top down: terminal, winding and iron core, the required space of this structure is larger, can not satisfy the less size requirements of some installation environments.
The utility model content
For the problems referred to above, problem to be solved in the utility model provides a kind of built-in voltage transformer.
The technical solution of the utility model is as follows:
A kind of built-in voltage transformer, comprise a terminal in shell and the shell, winding, iron core, described iron core is rectangle, a winding is divided into two parts and is wrapped on the limit unshakable in one's determination, winding and parallel placement unshakable in one's determination, one time terminal is arranged on the shell, and the position of a corresponding winding is provided with projection on the described shell.
Further, the bottom of described shell is provided with mounting panel.
Further, a described terminal is arranged on the recessed position of upper surface of outer cover.
The beneficial effects of the utility model are: owing to adopt technique scheme, compact conformation has effectively reduced volumetric spaces.

Fig. 2 is front view of the present utility model;
Fig. 3 is vertical view of the present utility model.
Wherein: 1, iron core 2, a winding 3, a terminal
4, shell 5, mounting panel
Embodiment
Below in conjunction with accompanying drawing a kind of preferred embodiment of the present utility model is made brief description.
As shown in Figures 1 to 3:
A kind of built-in voltage transformer, comprise a terminal 3 in shell 4 and the shell 4, winding 2, unshakable in one's determination 1, described unshakable in one's determination 1 is rectangle, winding 2 is divided into two parts and is wrapped on unshakable in one's determination 1 the limit, winding 2 and 1 parallel placement unshakable in one's determination, one time terminal 3 is arranged on the recessed position of shell 4 upper surfaces, and the bottom of described shell 4 is provided with mounting panel 5, and the position of a corresponding winding 2 is provided with projection on the shell 4.
A described winding 2 is divided on the length of side of iron core 1 that two parts are wrapped in rectangle, placement in parallel, and shell 4 forms the contour structures of concave-convex surface according to the shape of the iron core 1 of inside and a winding 2.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
