Description

Insulation closed busbar for industrial frequency converter

Technical Field

The utility model relates to an industry converter field, especially an insulating seal that industry converter was used arranges.

Background

With the development of the industrial frequency converter industry, people pay more and more attention to the problems of energy conservation, efficiency, cost and the like in the industry. In the same way, the application of the busbar for the industrial frequency converter in the industry is very wide, and the busbar technology is mature day by day. If a head horn needs to be exposed in an increasingly saturated industrial busbar industry, the traditional process barrier needs to be broken through, a busbar sealing technology with higher efficiency and lower cost is developed and researched, the product quality can be improved, and the cost is reduced to improve the competitiveness of the busbar sealing technology in the whole industry. The development of the industry is just due to the continuous innovation of the technology, and the continuous progress of the whole industry is promoted.

The common female insulating banding technique of arranging of present trade is lamination formula sealing technique, though this kind of mode can satisfy the service function who arranges commonly used, nevertheless from efficiency and quality, can't satisfy people to less installation space gradually, higher installation effectiveness, lower manufacturing cost's demand, and when using the structure product that needs bend, very easily appear the fracture, increase the electrical property risk. The existing laminated insulating film closed structure is that insulating films are respectively attached to two sides of a conducting layer, and then the conducting layer and the insulating films are compounded together in a hot pressing mode. The lamination type insulation sealing technology has the following defects:

(1) the edge sealing area is longer, and the width and the size of the edge-sealed busbar are not well controlled;

(2) the insulating film has upper and lower 2 layers, and the insulating film is typeset once more and is lost once more when being cut;

(3) the utilization rate of a space of a closed die needing limiting is lower, and the efficiency of the same press is 24pcs/1H when the press is fully loaded;

(4) the split layer is easy to crack when the steel plate is bent.

Therefore, it is necessary to provide a new structure to solve the above problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an insulating sealed mother that insulating film can not ftracture arranges, the utility model provides a following technical scheme:

the utility model provides an industrial frequency converter is with female arranging of insulating seal, this female arranging includes the conducting layer and the insulating film that press fit together through the mode of pressfitting, the insulating film is the conducting layer of single insulating film parcel cover.

As an optimized scheme of the utility model, female arranging has bending structure, the angle of bending is 30 ~ 90.

As another preferred scheme of the utility model, the thickness of insulating film is 0.1 ~ 0.5 mm.

As another preferred scheme of the utility model, female insulating film of arranging is bend in advance 60 ~ 90 earlier, then the cladding is in the surface of conducting layer, carries out the pressfitting again, and female arranging after the pressfitting is bent again.

The utility model has the advantages that:

1. the utility model adopts the whole insulating film and the conducting layer to carry out hot pressing, reduces the stress generated when a single film at the single side of the conducting layer is bent, and avoids the cracking of the insulating film in the bending process;

2. the utility model discloses the structural insulation film quantity has been practiced thrift 10%, and production efficiency has improved 25%.

Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

As attached figure 1 the utility model discloses the structure schematic diagram shows, an industry is female arranging of insulating seal for converter, and this mother arranges including conducting layer 2 and insulating film 1, and insulating film 1 covers the whole of conducting layer 2 for the parcel of sola insulating film. The conductive layer 2 is long, and the insulating film 1 is also long. The thickness of the insulating film 1 is 0.2mm, the length of the conducting layer 2 is 52cm, the insulating film 1 is bent by 80 degrees along the length direction, then the bent insulating film 1 is coated on the surface of the conducting layer 2 and is pressed by a press, and two end parts of the insulating film 1 are pressed together after being pressed to form a closed structure, namely a cylindrical insulating film is sleeved on the surface of the conducting layer 2 and then pressed together. After the pressing is finished, the busbar is bent in the length direction and is bent for 90 degrees, and the insulating film 1 is a whole film, so that the insulating film 1 cannot crack in the pressing process of the busbar, and the safety of a product is ensured.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can be covered within the protection scope of the present invention without the changes or substitutions thought by the inventive work within the technical scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
