Abstract
A bascule current transformer comprising a mainbody and a hoop is provided. The mainbody of the current transformer is bascule two-body structure with a plurality of projections arranged on, the same number of locating holes are arranged on the hoop, the locating holes match with the projection, a clasp which can ensure the good fixation between the mainbody and the hoop is arranged on the projection. The device which adopts structures of the utility model, after the locating hole of the hoop is embedded with the projection of the mainbody and the clasp is arranged on the projection, when the installation dividing the transformer into two parts, the hoop and the mainbody can be fixed well, the operator can control the divided transformer well with convenient and safe use; In addition, the utility model adopts a stainless steel band and a bolt to connect and fix tightly, which can make the lock-up more stable and reliable to achieve good magneto conductivity.
Description
Technical field
The utility model relates to a kind of instrument transformer, refers more particularly to a kind of current transformer.
Background technology:
The open-close type current transformer that prior art is used can be with the instrument transformer dimidiation during installation, and middle fenestra passes for a bus, tightens with bolt tying up then with circles such as plastic tape hoop.Owing to tie up with existing technical method, in the time of when mounted can be with the instrument transformer dimidiation, the operator be difficult to the instrument transformer after the control split, if careless, half of instrument transformer falls on the ground easily, uses inconvenience, and be dangerous.In addition, a kind of open-close type current transformer is arranged at present on the market, on current transformer body, be provided with some projections, the circle hoop uses the plastic tape material, the circle hoop of plastic tape is provided with the location hole of same number, after the location hole of the circle hoop of plastic tape is inserted projection on the current transformer body, the head of the circle hoop of plastic tape adopts the hasp type fastening means, this structure is because after the location hole of the circle hoop of plastic tape inserts projection on the current transformer body, owing to do not take other fixing means, when the dismounting open-close type current transformer, the projection on the current transformer body breaks away from the location hole of the circle hoop of plastic tape easily, causes unsafe factor, in addition, on the one hand, adopt the hasp type fastening means, may cause fastening not in place; On the other hand, circle hoop adopts materials such as plastic tape, and intensity is low, easy fracture, and the material aging phenomenon can appear in long-time use.Two above-mentioned defectives all might cause magnetic circuit to have air gap, and magnetic resistance can obviously increase, and the safety in production of electric power system is constituted sizable threat.
The utility model content
The purpose of this utility model is the deficiency that overcomes prior art, and provide a kind of simple in structure, reasonable in design, remove and install open-close type current transformer esy to use, safe and reliable.
The technical scheme that technical problem adopted that solves is:
1, a kind of open-close type current transformer comprises and is divided into current transformer body and circle hoop, current transformer body is for being open-close type two body structures, on current transformer body, be provided with some projections, the circle hoop is provided with the location hole of same number, the location hole of circle hoop is inserted the projection on the current transformer body, it is characterized in that: the location hole of above-mentioned circle hoop is provided with snap ring after inserting projection on the current transformer body on projection, and snap ring can guarantee that the current transformer body of two halves and circle hoop are fixing well.
2, a kind of open-close type current transformer, except that above-mentioned technical scheme, remain silent and be provided with screw in the pass of above-mentioned circle hoop, is furnished with bolt and connects fastening.
3, a kind of open-close type current transformer, except that above-mentioned technical scheme, above-mentioned circle hoop is a stainless steel band.
4, a kind of open-close type current transformer, except that above-mentioned technical scheme, above-mentioned current transformer body is provided with six projections, and the location hole that the circle hoop is provided with is six elongated holes.
The beneficial effects of the utility model are: after the location hole of above-mentioned circle hoop is inserted projection on the current transformer body, and on projection, be provided with snap ring, when the instrument transformer dimidiation is installed, circle hoop and current transformer body are for fixing well, the operator controls the instrument transformer after the split well, and is easy to use, safe; In addition, adopt and use stainless steel band to be connected fastening means, can make its locking firmer with bolt, reliable, reach good permeability.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the structural representation of the utility model embodiment;
