CN201425900Y - Integral fixed contact line clamp - Google Patents

Abstract

The utility model relates to an integral fixed contact line clamp, which belongs to a power transmission route appliances, no matter the line clamp is an upper fixed contact line clamp or a lower fixed contact line clamp, the line clamp is characterized in that the middle portion of a circular arc bracket body of a pipe nut line clamp and the middle portion of a circular arc line clamp are connected into a whole through a rectangular connecting plate. The line clamp has the advantages that the construction is convenient, the manufacturing efficiency is improved, the quality accidents caused byimperfect contact of planes is avoided, raw materials in manufacturing are saved, and the cost of the products is reduced.

Description

Integral type fixed contact wire clamp

Technical field

The utility model belongs to the power transmission and transformation line equipment, especially relates to a kind of fixed contact wire clamp.

Background technology

Existing fixed contact wire clamp, no matter be that wire clamp or fixed contact drop wire clip are split-type structural mostly on the fixed contact, be the pipe bus wire clamp that is ⊥ shape of wire clamp on the fixed contact and install between the circular arc wire clamp of lead, the vertical plate imbrication of the two is coupled together by bolt; The fixed contact drop wire clip also is to couple together with bolt after the two the vertical plate imbrication of pipe bus wire clamp that will be ⊥ shape and the circular arc wire clamp that lead is installed; Such split-type structural is made troubles to site operation on the one hand, and the interplanar loose contact owing to the two vertical plate causes resistance to increase on the other hand, and product quality problem easily takes place.

Summary of the invention

The purpose of this utility model provides a kind of integral type fixed contact wire clamp, and not only easy construction is increased work efficiency, and saves material, reduce cost, and also safe and reliable.

The purpose of this utility model is achieved like this: a kind of integral type fixed contact wire clamp, no matter be upper static contact wire clamp or following fixed contact wire clamp, include pipe bus wire clamp and circular arc wire clamp, it is characterized in that between the middle part of the middle part of the circular arc supporter groove of pipe bus wire clamp and circular arc wire clamp, being provided with the cuboid connecting plate and be connected and make one; So just do not have the contact-making surface of imbrication between the two, its advantage is easy construction, has improved operating efficiency, can not cause quality accident because of plane contact is bad, has also saved raw material in the manufacturing, has reduced product cost; Product uses in transformer station, makes to form the water conservancy diversion path between aluminum pipe type bus and the copper pipe bus respectively, and when making isolation switch contact and copper busbar closing operation, has the weakening effect.

The integral type fixed contact wire clamp that the utility model proposed, simple in structure, safe and reliable, saved raw material, reduced product cost.

Now in conjunction with the accompanying drawings and embodiments the integral type fixed contact wire clamp that the utility model proposed is described further.

Description of drawings

Fig. 1 is that the integral type fixed contact wire clamp master that the utility model proposes looks schematic diagram.

Among Fig. 1: 1, pipe bus wire clamp 2, circular arc wire clamp 3, connecting plate

Specific implementation method:

As can be seen from Figure 1: a kind of integral type fixed contact wire clamp, no matter be upper static contact wire clamp or following fixed contact wire clamp, include pipe bus wire clamp 1 and circular arc wire clamp 2, it is characterized in that between the middle part of the middle part of the circular arc supporter groove of pipe bus wire clamp 1 and circular arc wire clamp 2, being provided with cuboid connecting plate 3 and be connected and make one; So do not have the contact-making surface of pipe bus wire clamp 1 and circular arc wire clamp 2 imbrication between the two, its advantage is easy construction, has improved operating efficiency, can not cause quality accident because of plane contact is bad, has also saved raw material in the manufacturing, has reduced product cost.

Claims (1)

1, a kind of integral type fixed contact wire clamp, comprise pipe bus wire clamp (1) and circular arc wire clamp (2), it is characterized in that between the middle part of the middle part of the circular arc supporter groove of managing bus wire clamp (1) and circular arc wire clamp (2), being provided with cuboid connecting plate (3) and be connected and make one.
