Description

Equipment copper-aluminum transition butt-welding clamp anti-break support plate

technical field

The utility model relates to the field of substation equipment accessories, in particular to a copper-aluminum transition butt welding type line clip anti-break supporting plate for equipment.

Background technique

As an important accessory of the power grid equipment, the equipment clamp is widely used in the power grid system. The copper-aluminum transition clamp of the welding type equipment has a high accident rate. The accident caused by the breakage of the equipment clamp has a great impact on the safe and stable operation of the power grid. a greater threat.

In order to prevent accidents, the copper-aluminum transition clamps of the equipment were replaced in time, and brazed copper-aluminum transition equipment clamps were used to eliminate hidden dangers of accidents. However, the power outage time for replacing brazed-type clamps is relatively long, and the cost of materials is relatively high.

Utility model content

The purpose of the utility model is to provide a copper-aluminum transition butt welding type wire clip anti-crack support plate for equipment with simple structure and low cost, which can prevent equipment wire clips from breaking.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a copper-aluminum transition butt welding type line clamp anti-break supporting plate, including the supporting plate, the height of the left end of the supporting plate is higher than the height of the right end of the supporting plate, and the left end of the supporting plate is provided with The connecting hole is equipped with U-shaped bolts with openings downwards on the right end of the supporting plate.

The upper surface of the right end of the supporting plate is provided with a groove extending left and right and recessed downward, and the groove is located between the openings of the U-shaped bolts in the middle of the right end of the supporting plate.

The U-bolts are two left and right arranged side by side.

The connecting holes are provided in two rows, each with two rows.

The supporting plate is made of stainless steel or epoxy resin plate.

The end of the U-shaped bolt passing through the supporting plate is provided with a flat pad, a spring pad, and a nut in sequence.

The copper-aluminum transition butt welding type line clip anti-break supporting plate of the utility model can be fixedly connected to the lower side of the equipment line clamp, the connecting hole at the left end of the support plate can be bolted to the flat part of the equipment line clamp, and the right end of the support plate The U-bolt can be used to fix the column part of the equipment clamp. The heights of the left and right sides of the supporting plate are different to facilitate fitting with the equipment clips. Notches facilitate positioning of equipment cord clips. The supporting plate is made of stainless steel or epoxy resin plate, which is basically non-conductive and will not generate eddy currents. The supporting plate has a relatively large bending moment resistance, which can effectively prevent the copper-aluminum transition clip from breaking. The supporting plate has a simple structure and relatively economical material costs. Since the installation of the supporting plate does not change the original clamp structure, the installation is convenient and the installation time is relatively short.

Detailed ways

A copper-aluminum transition butt-welding wire clip anti-break support plate for equipment shown in Figure 1-3 includes a support plate made of stainless steel or epoxy resin. The height 1 of the left end of the support plate is higher than the height 3 of the right end of the support plate. The left end 1 of the supporting plate is provided with connecting holes 2, and the connecting holes 2 are arranged in two rows, each row being two. The right end 3 of the supporting plate is provided with a U-shaped bolt connecting hole, and the right end 3 of the supporting plate is equipped with a U-shaped bolt 5 with an opening downward through the U-shaped bolt connecting hole. The U-shaped bolts 5 are two arranged side by side, and the ends of the U-shaped bolts 5 passing through the supporting plate are provided with a flat pad 6 , a spring pad 7 , and a nut 8 in sequence. The upper surface of the right end 3 of the supporting plate is provided with a groove 4 extending left and right and recessed downward, and the groove 4 is located between the openings of the U-shaped bolt 5 in the middle of the right end 3 of the supporting plate.

The copper-aluminum transition butt welding type wire clip anti-break supporting plate of the utility model can be fixedly connected to the lower side of the equipment wire clamp, and the connecting hole 2 at the left end 1 of the supporting plate can be bolted to the flat part of the equipment wire clamp. The U-bolt 5 at the right end 3 of the plate can be used to fix the column part of the equipment clamp. The heights of the left and right sides of the pallet are different to facilitate fit with the equipment clips. The groove 4 can facilitate the positioning of the equipment wire clamp. The supporting plate is made of stainless steel or epoxy resin plate, which is basically non-conductive and will not generate eddy currents. The supporting plate has a relatively large bending moment resistance, which can effectively prevent the copper-aluminum transition clip from breaking. The supporting plate has a simple structure and relatively economical material costs. Since the installation of the supporting plate does not change the original clamp structure, the installation is convenient and the installation time is relatively short.
