Abstract

Provided is a transformer pull tab fixing structure. The transformer pull tab fixing structure comprises a transformer body. Two pull tab fixing plates are welded on the transformer body. Two ends of a pull tab are fastened on the fixing plates. U-shaped necks are arranged on the fixing plates. An insulation sleeve is arranged in each neck in a clamping mode. The two ends of the pull tab are respectively pressed in insulation sleeves, and a fixing structure is formed. At least one fixing plate is provided with a set of earth stud. A ground lead is connected between the earth stud and the pull tab. The pull tab is ensured that only one point of the pull tab is connected with the ground. Due to the fact that a fixing mode of the pull tab is improved, the transformer pull tab fixing structure has the advantages of avoiding occurrence of falling accidents of pull tabs of transformers, being simple in structure, convenient to use and install and capable of effectively fixing the pull tab of the transformer, preventing the pull tab of the transformer from falling off, and satisfying a demand of long-term safe running of the transformer.

Description

A kind of transformer pull band fixed structure

Technical field

The utility model relates to the transformer technology field, specifically a kind of transformer pull band fixed structure.

Background technology

Transformer can produce vibrations unavoidably when operation, vibrations can cause again the loosening of fastening bolt unavoidably, iron core strap faces this problem equally, if the fastening bolt of drawstring is loosening, cause that drawstring comes off, the high voltage of transformer body easily to drawstring discharge or drawstring itself with the coil partial short circuit of transformer own, will cause security incident, affect the normal operation of transformer.

The utility model content

The utility model provides a kind of transformer pull band fixed structure, and it is simple in structure, and is easy to install and use, and the more effective stationary transformer drawstring of energy has been avoided the generation of transformer pull band case accident, has solved problems of the prior art.

The technical scheme in the invention for solving the technical problem is: a kind of transformer pull band fixed structure, comprise transformer body, be welded with two drawstring fixed heads at described transformer body, the drawstring two ends are fastened on the fixed head, it is characterized in that, be provided with the U-shaped draw-in groove at described fixed head, in described U-shaped draw-in groove, be arranged with an insulating case, described drawstring two ends are pressed on respectively in the described insulating case, form fixed structure; And at least one fixed head one cover ground connection bolt is set, between described earth stud and drawstring, connects a ground lead, guarantee that drawstring has and only have one point earth.

The beneficial effects of the utility model are: the utility model is by improving the fixed form of drawstring, avoided the generation of transformer pull band case accident, modification scheme is simple in structure, easy to install and use, energy is the stationary transformer drawstring effectively, avoid transformer pull band to come off, satisfied the demand of transformer long-term safety operation.

Embodiment

Such as Fig. 1～shown in Figure 7,

For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.

As shown in Figure 1, the utility model comprises two drawstring fixed heads 1, two are fixedly welded on the transformer body, be provided with the U-shaped draw-in groove at fixed head, in the U-shaped draw-in groove, be arranged with an insulating case, drawstring 3 two ends by insulating case 2 with fixed head 1 insulation and be fixed on the fixed head 1, and by ground lead 5 and the safety ground mode that is fixed on earth stud 4 and fixed head 1 on the fixed head 1 and is formed with and only has one point earth.

Installation process such as Fig. 2 be to shown in Figure 7, and installation process is, drawstring 3 two ends are slipped in the U-shaped draw-in groove, then insulating case is nested with between drawstring and U-shaped draw-in groove, formed tight fit, and ground lead 5 is installed.

During use, the utility model member is installed between transformer core and the device body, and the stationary transformer drawstring satisfies the demand that the transformer long-term safety is moved safely and effectively.

Except the described technical characterictic of specification, be the known technology of those skilled in the art.
