Abstract
The utility model discloses a secondary wire-outgoing connecting structure of a transformer. The structure comprises an annular transformer main body and a rubber fixing sleeve, wherein a spring clamp is arranged in the center hole of the transformer main body; mounting holes are uniformly formed in both sides of the transformer main body in a hoop direction; fixing feet matching with the mounting holes are arranged on the inner wall of the rubber fixing sleeve; tensioning band holes through which tensioning bands can penetrate are formed in both ends of the rubber fixing sleeve. The structure has the advantages that the transformer is mounted simply and fixedly firmly.
Description
Technical field
The utility model relates to the instrument transformer that detects electric current, specifically the syndeton of secondary outlet in a kind of instrument transformer.
Background technology
Cable straight-through current transformer is the product often adopting in electric power system; use as current measurement or relaying protection; because what its line adopted is high voltage insulation cable; supporting current transformer is that form of bus bars is set in high voltage insulation cable outside one time; realize the measurement of electric current; due to the instrument transformer of the outdoor transformer top in transformer; comparatively bother in wiring; particularly connect secondary outlet; need to use screwdriver to tighten, operation aloft makes screwdriver be highly susceptible to dropping.
Summary of the invention
The purpose of this utility model is, provide a kind of be convenient to the instrument transformer installed secondary go out wire connection structure.
In order to achieve the above object, the technical scheme that the utility model proposes is: instrument transformer secondary go out wire connection structure comprise, be connected to contact, binding post and the fastening cap of the secondary leading-out terminal of instrument transformer, described contact is the cylinder of hollow, in hollow space, be provided with power spring, described fastening cap is provided with wire hole, and described binding post one end is provided with patchboard, and described fastening cap and contact are threaded.
The utility model has the advantage of, in connecting instrument transformer secondary outlet, by electric wire through in fastening cap again the end of a thread be connected on patchboard, binding post is inserted to the hollow bulb of contact, make binding post and power spring close contact, subsequently fastening cap is connected fastening with contact.
Further, fastening for secondary wire is connected with binding post, described patchboard is provided with cable clamping interface, and the wire in the end of a thread is wrapped in cable clamping interface, by the restriction of cable clamping interface, the tension effect of secondary wire is strengthened.
Finally, in order to prevent that rainwater from flowing in fastening cap, the wire hole of described fastening cap is provided with sealing ring, in the time of the rainy day, can stop that by sealing ring effect rainwater flows in fastening cap.
Brief description of the drawings
Fig. 1: be the structural representation of the casing of being convenient to the transformer of installing and lifting of the present utility model.
Embodiment
As shown in Figure 1 be instrument transformer secondary go out wire connection structure comprise, be connected to contact 2, binding post 4 and the fastening cap 5 of 1 level leading-out terminal of instrument transformer, the cylinder that contact 2 is hollow, in hollow space, be provided with power spring 3, fastening cap 5 is provided with wire hole, binding post 4 one end are provided with patchboard 6, and described fastening cap 5 and contact 2 are threaded.
In connecting 1 level outlet of instrument transformer, electric wire 7 is passed in fastening cap 5, then the end of a thread is connected on patchboard 6, binding post 4 is inserted to the hollow bulb of contact 2, make binding post 4 and power spring 3 close contacts, subsequently fastening cap 5 is connected fastening with contact 2.
On patchboard, 6 are provided with cable clamping interface 8, and the electric conductor of electric wire 7 is wrapped in cable clamping interface 8, by the restriction of cable clamping interface 8, the tension effect of secondary electric wire 7 are strengthened.
The wire hole of fastening cap 5 is provided with sealing ring, in the time of the rainy day, can stop that by sealing ring effect rainwater flows in fastening cap 5.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; the length and the size that change overflow pipe, these also should be considered as protection range of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
