Abstract

The utility model discloses a clamping device applied to a current transformer. The clamping device comprises an outer shell which is packaged with a magnetizer, and is characterized in that the outer shell is formed by oppositely buckling two shells, a central through hole which is provided with a cable penetrating cable is arranged at the middle part of the outer shell, one ends of the two shells are connected through a hinge, and the other ends of the two shells are connected through a clamping piece. By adopting the structure, under the condition without switching off a power cable, the clamping device disclosed by the utility model can be directly clamped on the power cable, the structure is simple, the installation is convenient, the sampling work for the current of the power cable can be convenient as well, and the break maintenance and the later-period additional assembly of the current transformer can be facilitated; and in addition, the clamping device adopts the buckling type connection, the current transformer can be divided into two parts, a rigid shell is additionally provided, the water-proof and wet-proof performance is excellent, the buckling type connection is firmer, the clamping device is not easy to age, and the current transformer can be enabled to be fixed on a cable grounding wire in a long time.

Description

A kind of clamping apparatus that is applied to current transformer
Technical field
The utility model relates to a kind of fixture, specifically a kind of clamping apparatus that is applied to current transformer.
Background technology
Current transformer now commonly used is exactly the ring device that is wound with winding on the complete magnet ring of closure, is an inseparable closed circular hole in the middle of the device.Therefore, the current transformer of this closing structure need pass power cable and could accomplish the equipment wiring when mounted from closed circular hole; Like this; Trouble not only is installed, and is not easy to overhaul afterwards and installs current transformer additional, restricted its scope of application with the later stage.
At present, some improved current transformers adopt flexible Luo-coils, and just the coil with a softness is converted into circle, in order to around cable, and the two ends of circular coil are connected with nut through the plastics screw fixing, thereby the purpose that realization is fixed.Though need not breaking off cable, this connected mode from closed circular hole, do not pass; Made things convenient for installation, still, but had following two problems: 1) phenomenon of aging distortion appears in plastics screw, nut easily; Can cause nut distortion cavity to enlarge after working long hours; Thereby the strength phenomenon of loosening or automatic opening inadequately occurs connecting, what current transformer can not be long-time, firm is fixed on the earth connection, finally causes image data inaccurate; 2) this connected mode requirement coil must be a flexible coil; Flexible coil thinks that the inferior position of specific rigidity coil is apparent in view; It can not adopt metal shell structure more firm, better tightness; The phenomenon of deterioration sensor performances such as behind the long-play, making moist can appear in sensor internal, distortion.
The utility model content
For overcoming the deficiency that above-mentioned prior art exists, the utility model technical problem to be solved has been to provide a kind of clamping apparatus that is applied to current transformer, and it is not only simple in structure, and easy for installation.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of clamping apparatus that is applied to current transformer; Comprise the shell body that is packaged with magnetic conductor; It is characterized in that; Said shell body is formed by the relative fastening of two housings and the centre has the central through hole that installs cable, and said two housing one ends connect through hinge, and the other end passes through the fastener connection.
Said fastener comprises the buckle post and the buckle cover of mutual clamping, and said buckle post and buckle cover are separately positioned on two housings, and said buckle cover is provided with safeties.
Said housing adopts spray piano lacquer steel skeleton structure body.
Said housing central through hole place medial surface is provided with protective layer, and said protective layer is by the water proof flexible material.
The beneficial effect of the utility model is; After adopting said structure; The utility model need not break off under the situation of power cable, and directly card is placed on the power cable, and is not only simple in structure, easy for installation; And make things convenient for the sampling work of power cable electric current, help overhauling afterwards and install current transformer additional with the later stage.In addition, the utility model has adopted the buckle-type connection, can current transformer be divided into two, and adds outer rigid housing, waterproof and dampproof superior performance, and buckle connection simultaneously is more firm, is not easy to wear out, and can guarantee for a long time that transducer is fixed on the cable grounding line.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Structural representation when Fig. 1 is the utility model installation;
Structural representation when Fig. 2 is the utility model open mode;
Among the figure, 1 housing, 2 hinges, 3 fasteners, 31 buckle posts, 32 buckle covers, 4 central through holes, 5 protective layers.
Embodiment
As depicted in figs. 1 and 2, a kind of clamping apparatus that is applied to current transformer of the utility model comprises the shell body that is packaged with magnetic conductor.Said shell body is formed by two housings, 1 relative fastening and the centre has the central through hole 4 that installs cable, and said two housings 1 adopt spray piano lacquer steel skeleton structure body, and an end passes through hinge 2 connections, and the other end passes through fastener 3 and connects.Said fastener 3 comprises the buckle post 31 and buckle cover 32 of mutual clamping, and said buckle post and buckle cover are separately positioned on two housings, and said buckle cover 32 is provided with safeties, causes dropping owing to misoperation in order to preventing.The central through hole place medial surface of said housing 1 is provided with protective layer 5, and said protective layer 5 is by the water proof flexible material, in order to the protection power cable.
During installation, at first two housings of the utility model are opened, power cable is put in the central through hole, then two housings are carried out closure, again the buckle cover is stuck on the buckle post, and it is pinned, prevent because misoperation causes dropping through safeties.When needs are taken the utility model, need to touch safeties and carry out release, then the buckle cover is broken into two with one's hands from the buckle post, thereby separated two housings.
