Abstract
The utility model provides an open-close type current inductor. The open-close type current inductor comprises a base, iron cores, secondary windings and an insulating shell, wherein the insulating shell is arranged on the base; the iron core and the secondary winding are arranged inside the insulating shell; the current inductor has an open-close type two-piece structure; the iron core is formed by arranging an upper C-shaped iron core and a lower C-shaped iron core oppositely; the secondary windings are arranged on the upper C-shaped iron core and the lower C-shaped iron core; the two C-shaped iron cores comprise a silicon steel sheet layer and an amorphous alloy layer respectively; a surrounding hoop is arranged at the periphery of the insulating shell; retainer rings are arranged on the front side and the back side of the surrounding hoop; and the two ends of the surrounding hoop are fixed by a nut and a bolt. The open-close type current inductor is convenient to install, relatively low in loss, low in cost and energy-saving; and the surrounding hoop and the retainer rings can clamp the current inductor so as to further fix the current inductor.
Description
Technical field
The utility model relates to a kind of instrument transformer, relates in particular to a kind of open-close type current transformer.
Background technology
In the process of production and applied current instrument transformer; We extremely pay close attention to the cost and the result of use of current transformer; And the tendency cost is low, and the current transformer that effectiveness is high is with this; How to reduce cost in process of production, can make simultaneously again current transformer in use can structure firm and easy to use be the problem that the needs that run in the production process solve.
Summary of the invention
The purpose of the utility model provides a kind of open-close type current transformer and solves undesirable its property easy to use of structure steadiness that exists in the prior art and the problem that need reduce cost.
The technical solution of the utility model is:
A kind of open-close type current transformer comprises base, iron core, secondary winding and insulation crust, and said base is provided with said insulation crust; Be provided with iron core and secondary winding in the said insulation crust; Said current transformer is the current transformer of folding two body structures, and said iron core forms for two C sections cores up and down are provided with in opposite directions, and said secondary winding is located on said two C sections cores up and down; Said two C sections cores are by silicon steel lamella and the two-layer composition of amorphous alloy layer; Said insulation crust periphery is provided with encloses hoop, and said both sides, front and back of enclosing hoop are provided with back-up ring, and said two ends of enclosing hoop are fixed by nuts and bolt.
A kind of open-close type current transformer of the utility model is the current transformer of folding two body structures, and is easy for installation.Its iron core has silicon steel lamella and amorphous alloy layer, can make the volume and weight that reduces instrument transformer to a certain extent, and the magnetic property of non-crystaline amorphous metal is outstanding, can reduce the loss value of instrument transformer to a certain extent, reduces cost, and saves the energy.Simultaneously, very responsive because of non-crystaline amorphous metal to mechanical stress, be provided with in the intermediate layer of structure to the firm amorphous alloy layer of silicon steel lamella, prevent that iron core from going wrong because of mechanical stress.Enclose hoop and can stick current transformer, further instrument transformer is played fixation.
The beneficial effect of the utility model is: a kind of open-close type current transformer of the utility model, and easy for installation, loss value is lower, and cost is low, saves the energy, encloses hoop and back-up ring and can stick current transformer, further instrument transformer is played fixation.
