Abstract
The utility model provides a E type current transformer, it includes a E sections core, the 2nd E sections core, the primary winding, secondary winding, the bottom plate and the pouring body, a E sections core and the 2nd E sections core relative placement are in order to form the first window and second window, the primary winding winds into from the first window, from the second window around going out, on the center pillar of secondary winding winding between the first window and second window, the 2nd E sections core is fixed on the bottom plate, the pouring of the pouring body is outside primary winding and secondary winding, it pours into a mould the slot of personally experiencing sth. Part of the body to be equipped with the same encircleing of multichannel size on pouring body coupling bottom plate is just poured into a mould and is personally experienced sth. Part of the body. In this way, the utility model discloses can seal the protection to the winding.
Description
Technical field
The utility model relates to instrument transformer technical field, particularly relates to a kind of E type current transformer.
Background technology
The operation principle of current transformer is electromagnetic induction, is generally made up of the iron core closed and winding.Big current scaling transformation is mainly become standard small area analysis by the function of current transformer, to realize standardization, the miniaturization of measuring instrument, proterctive equipment and automatic control equipment.
At present, the winding of existing current transformer is mostly exposed outside iron core, can not play a protective role to winding.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of E type current transformer, can carry out closed protective to winding.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of E type current transformer, comprise an E shaped iron core, 2nd E shaped iron core, a winding, secondary winding, base plate and pour mass, a described E shaped iron core and described 2nd E shaped iron core staggered relatively to form first window and Second Window, a described winding moves into from described first window, lay out from described Second Window, described secondary winding is wrapped on the center pillar between described first window and Second Window, described 2nd E shaped iron core is fixed on described base plate, described pour mass is cast in outside a described winding and described secondary winding, described pour mass connects described base plate and described pour mass is provided with the identical groove around described pour mass of multiple tracks size.
Preferably, described pour mass is epoxy resin poured body.
Be different from the situation of prior art, the beneficial effects of the utility model are: by pouring into a mould pour mass outward at a winding and secondary winding, thus can carry out closed protective to winding.
Accompanying drawing explanation
Fig. 1 be the utility model embodiment E type current transformer partly cut open structural representation.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
See Fig. 1, the utility model embodiment E type current transformer partly cut open structural representation.The E type current transformer of the utility model embodiment comprises an E shaped iron core 1, the 2nd E shaped iron core 2, winding 3, secondary winding 4, base plate 5 and a pour mass 6.
One E shaped iron core 1 and the 2nd E shaped iron core 2 staggered relatively to form first window 11 and Second Window 12, one time winding 3 moves into from first window 11, lay out from Second Window 12, secondary winding 4 is wrapped on the center pillar between first window 11 and Second Window 12,2nd E shaped iron core 2 is fixed on base plate 5, pour mass 6 is cast in outside a winding 3 and secondary winding 4, pour mass 6 connecting bottom board 5 and pour mass 6 is provided with the identical groove 61 around pour mass 6 of multiple tracks size.In the present embodiment, the quantity of groove 61 is three.Groove 61 may be used for the binding post of placement winding 3 or secondary winding 4.
In the present embodiment, pour mass 6 is epoxy resin poured body, can improve insulation effect.
By the way, the E type current transformer of the utility model embodiment by pouring into a mould pour mass outward at a winding and secondary winding, thus can carry out closed protective to winding.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
Claims (2)
