Abstract
The invention relates to a multi-turn inverted current transformer, in particular to a small-current-ratio inverted current transformer, which belongs to the technical field of transformer manufacturing. The invention adopts a technical scheme that: the multi-turn inverted current transformer comprises an expander (1), a primary lead (2), a transformer body (3), an oil cabinet (4), a ceramic sleeve (5) and a base (6); the ceramic sleeve is arranged on the base and is provided with the oil cabinet and the transformer body; the expander is arranged on the top; and the primary lead passes through the iron core of the transformer body for many times to form multiple turns, wherein every time the lead passes through the iron core of the transformer body, a turn is formed. The multi-turn inverted current transformer overcomes the drawback that one or two turns are formed at one pass and the drawback that the application is limited to a large current ratio of the conventional inverted transformer, and also overcomes the drawbacks of high cost, large volume and incapability of realizing error performance of small-current-ratio inverted transformers. In addition, rectangular structures which are parallel are formed at the connection part of a primary conductive rod and the lead and are fixed in two parallel rectangular insulated base plates, and a primary outgoing terminal meets an anti-rotation requirement.
Description
Affiliated technical field:
The present invention relates to a kind of multiturn inverted type current transformer, the inverted type current transformer of particularly little current ratio belongs to instrument transformer manufacturing technology field.
Background technology:
Traditional inverted type current transformer once mostly is a circle or two circles, be applicable to big current ratio requirement, inverted type current transformer for little current ratio, realize that cost is low, volume is little and the satisfying of error performance, must improve its number of ampere turns, this just needs to improve a number of turn, and will satisfy the requirement of its outlet terminal anti-rotation.
Summary of the invention:
The object of the invention provides a kind of multiturn inverted type current transformer, realizes the requirement of the little current ratio of inverted type current transformer, and the requirement of an outlet terminal realization anti-rotation, solves the problems referred to above that exist in the background technology.
Technical scheme of the present invention is:
A kind of multiturn inverted type current transformer, comprise expander, once lead-in wire, device body, oil conservator, insulator, base, insulator is set on the base, oil conservator, device body are set above the insulator, expander topmost is set, once lead-in wire passes device body several unshakable in one's determination, realize multiturn, whenever pass once is a circle, for preventing that the outlet terminal from rotating, one time outlet terminal adopts the rectangle structure that is parallel to each other with the position that connects that goes between, and is fixed in two rectangle insulating pads that are parallel to each other, and the distance of two insulating pads has only 1mm.
Good effect of the present invention is: overcome traditional inverted type current transformer and once mostly be a circle or two circles, only be applicable to big current ratio requirement; The inverted type current transformer that has overcome little current ratio is wanted the cost height, the shortcoming that volume is big, error performance is not easy to satisfy.Inverted type current transformer once adopts the lead type structure, can realize the form of a multiturn, has realized the requirement of the little current ratio of inverted type current transformer; And rectangle structure parallel to each other is adopted at the position that the primary conductive bar connects with lead-in wire, and is fixed in two rectangle insulating pads parallel to each other, and an outlet terminal has been realized the requirement of anti-rotation.
