Description

Single hook insulation connecting plate

Technical field:

The utility model relates to the field of electric power transmission, in particular to a device for live replacement of double cross-arm tension-resistant suspension insulators in power distribution lines. the

technical background:

In the 10kV distribution line, the tension insulator is an important part of the line. It not only ensures the insulation between the wire and the cross arm and the tower, but also bears the tension of the wire in the horizontal direction. However, due to the special structure of 10kV distribution lines, insulators are prone to defects due to lightning strikes, external force damage, pollution, aging and other reasons, resulting in forced power outages on all lines. Therefore, it has become an urgent problem for electric power companies to develop tools that can bear all the loads of the tension insulator strings and match the structure of the insulators. the

The existing work project of live replacement of double cross-arm tension insulators mainly adopts the operation method of insulating rope sleeves, that is, using insulating rope sleeves to fix on the double cross-arms, and connecting with the tensioning device to replace the tension insulators. This operation method has the following disadvantages: 1. Because the insulating rope cover is made of soft insulating material, it is difficult to control during the operation, so that the operator and the charged body cannot maintain sufficient combined insulation, which may cause discharge accidents to the human body; 2. When using insulation During the operation of the rope sleeve, the insulating rope sleeve inevitably rubs against the cross arm, pole and other equipment, which not only loses part of the effective insulation length of the insulating rope, but also affects its good electrical performance and causes safety hazards; 3 , After using the wire tightening device to tighten the wire, it is impossible to effectively control the jumper of the branch line, and it is easy to force the jumper to cause it to break off at the T junction of the main line, generate a strong arc, or even hurt people or burn it 4. During the operation, two operators need to cooperate with each other to complete the operation. The average operation time for replacing a string of insulators is 60 minutes. The work efficiency is low and the process cannot be guaranteed. the

The opening slot is in the shape of a right-angled trapezoid inclined inwardly, and the inclination angle is 5°-30°, preferably 10°-20°. the

The link head is a ring-shaped structure made of high-strength alloy material. On the one hand, it meets the strength requirements, and on the other hand, the ring design is convenient to connect with other traction tools. the

There is a self-resetting anti-tripping on the jumper fixing hook. the

The main body of the connecting plate is connected with the fixing cards on the upper and lower sides of the main body of the connecting plate through insulating bolts. the

The fixed card is T-shaped, and has a card slot on it, and a corresponding sliding groove on the main body of the joint plate, so that the fixed card can be slidably connected in the length direction of the main body of the joint plate, so as to meet the firm fixing of double cross-arms of different widths. question. the

The beneficial effect that the utility model can reach is:

1. The utility model has a simple structure, but is easy to carry and use. It not only ensures the safe distance between the operator and the charged body, but also ensures the safety of the workers, and effectively controls the jumper, which greatly improves the work efficiency. the

2. The utility model has low manufacturing and use costs, is easy to produce in batches, and has a good promotion effect. It not only effectively guarantees work efficiency, avoids potential safety hazards, but also avoids large-scale power outages, reduces economic losses of enterprises, and ensures people's production and life. the
