Description
Technical field
The utility model relates to a kind of instrument transformer, relates more specifically to a kind of novel vertical punching and exchanges the general instrument transformer of accurate voltage electric current.Belong to the power electronic equipment technical field.
Background technology
At present the production technology of voltage, current transformer is very abundant, but that general situation is a versatility is bad, and the common product usage is single, exists the inaccurate shortcoming in pin location mostly with the instrument transformer of toroidal core production; Vertical encapsulation instrument transformer connects together feedthrough hole and shell mostly, and the epoxy resin face after the embedding is exposed outside, has influenced the attractive in appearance of instrument transformer profile greatly.
The present invention mainly is in order to address the above problem.
The utility model content
The purpose of this utility model provides the general shape instrument transformer of a kind of electric current and voltage, and it has the extremely strong characteristics of versatility, and production technology is simple, accurate positioning, and compact conformation, unique stem stem formula uniqueness novel in design and external form are more attractive in appearance.The general instrument transformer of vertical punching miniature precision electric current and voltage, it is characterized in that: form by toroidal core (1), two spacers (2) (4), stem stem (6) and shell (7), two groups of enamelled wires of toroidal core ring external application are fan-shaped to coiled coil (9), put into spacer, the lead-out wire of two windings links to each other with silver-colored post (8) on the spacer and welds together, spacer inside has step to fix magnetic core, puts into shell after assembling, and uses the epoxy resin embedding.
Description of drawings
Fig. 1 is transformer casing and stem stem figure
Fig. 2 is the finished figure after the instrument transformer embedding
Fig. 3 is an instrument transformer internal structure explosive view
Technical problem of the present utility model can solve by taking following measure, specifies below in conjunction with accompanying drawing:
(9) are coil among Fig. 3, and magnetic core (1) is toroidal core, and toroidal core can be with permalloy ring or ultramicro-crystal alloy, at two groups of fan-shaped opposing connections of enamel-covered wire of ring external application. 4 silver-colored posts (8) insert respectively in four through holes (3) of spacer (2), again silver-colored post is linked to each other with two windings and weld together, the silver post other end inserts four through holes of spacer (4), two spacers make the pin accurate positioning by both fixing silver-colored post, spacer inside has step (5) can play again the effect of fixed magnetic core, makes toroidal core be placed on the phenomenon that can not occur rocking in the shell. Shell shown in Figure 1 (7) is put in the assembling of coil and spacer, stem stem (6) was inserted the circular hole of transformer casing, use epoxy resin encapsulated, make it to become a totally enclosed device.
The beneficial effects of the utility model are: according to the utility model, this instrument transformer is compared with original instrument transformer has had highly versatile, the leading foot accurate positioning, compact conformation, manufacture craft is simple, and the remarkable advantage that the layman is more attractive in appearance is particularly suitable for using in industrial control system.
Embodiment
As a representative instance of the present utility model, for example, can adopt magnet ring to be of a size of (14*9-18), material is the permalloy ring with high permeability, each 1500 circle of the fan-shaped opposing connection of enamelled wire with 0.08mm can obtain most preferred embodiment of the present utility model.
