Description

Tightening Insulation Fixtures for Replacing Tension Porcelain Insulators When Live

technical field

The utility model belongs to an appliance for power transmission and transformation construction in the electric power industry, in particular to a tightening insulation fixture for replacing tension porcelain insulators with electricity.

Background technique

Since the transmission line runs in the field all the year round, it is affected by the natural environment, meteorological conditions and external damage for a long time. The porcelain insulators of the line will have zero value, drop in value or be damaged by lightning strikes. If it needs to be replaced, the transmission line will stop power transmission. Applying for it requires multi-department cooperation, and the process of replacing porcelain insulators requires the cooperation of many people. The labor intensity is high, it takes a long time, and there are many unsafe factors at the same time. The power failure of the line will affect the normal power supply and bring losses to users.

Contents of the invention

The purpose of this utility model is to overcome the above-mentioned technical deficiencies, and provide a convenient and fast replacement of porcelain insulators, which saves manpower and material resources, and is safe and reliable for tightening insulation fixtures for live replacement of tension-resistant porcelain insulators.

The technical solution adopted by the utility model to solve the technical problem is: the tightening insulation jig for replacing the tension-resistant porcelain insulator with electricity includes a cross-arm hanging point fixing frame, an insulating plate, a single-connected bowl head fixing frame, a single-connected bowl head, and a bottle holder Hanging ring, bottle holder, bottle holder fixing plate, which is characterized in that two parallel bottle holder fixing plates are installed under the two ends of the cross arm hanging point fixing frame on the left end of the jig, and two parallel The lower end of the bracket fixing plate is fixed with fastening bolts at one end of the two bottle racks, and the screw is threaded in the horizontal direction of the fixing frame of the cross-arm hanging point, and a screw nut with a handle is screwed on the screw, and the other end of the screw is Fix one end of the insulating plate with a fastening bolt, and the other end of the insulating plate is connected with a single bowl head with a fastening bolt, and the single bowl head is fixed on the two ends of the single bowl head fixing frame, The bottle holder rings are fixed under the two ends of the bottle holder, and the other end of the bottle holder is movably mounted in the bottle holder ring, and three reinforcing connecting ribs are fixed on two parallel bottle holders at equal distances.

The beneficial effects of the utility model are: the tightening insulation jig for replacing the tension-resistant porcelain insulator with electricity can deal with the insulator defect in the transmission line in time, the operation is very convenient, time and manpower and material resources are saved, the reliability of power supply is improved, and the reliability of the power supply is ensured. The safe operation of the line and the personal safety of operators.

In the figure, 1-cross-arm hanging point fixing frame; 2-leading screw; 3-screw nut; 4-insulation board; 5-single bowl head fixing frame; 6-bottle rack hanging ring; 8-bottle rack; 9-bottle rack fixing plate; 10-fastening bolt; 11-single bowl head.

Detailed ways

Embodiment, with reference to accompanying drawings 1-3, the tightening insulation jig for replacing the tension porcelain insulator with electricity is to install two parallel bottle holders under the two ends of the cross-arm hanging point fixing frame 1 on the left end of the jig Fixing plate 9, at the lower end of two parallel bottle holder fixing plates 9, fix an end of two bottle holders 8 with fastening bolt 10. Screw the lead screw 2 in the horizontal direction of the cross-arm hanging point fixed frame 1, screw a screw nut 3 with a handle on the lead screw 2, and the other end of the lead screw 2 fixes one end of the insulating plate 4 with a fastening bolt 10, The other end of insulating plate 4 connects single connection bowl head 11 with fastening bolt 10, and fixes with fastening bolt 10. Single-linked bowl head 11 is fixed on the two ends of single-linked bowl-head fixed mount 5, below the two ends of single-linked bowl-head fixed mount 5, the bottle holder hanging ring 6 is fixed, and the other end of bottle holder 8 is movably held. Be contained in the bottle holder hanging ring 6, fix three arc-shaped reinforcement connecting ribs 7 on two parallel bottle holders 8 at equal distances.

The method of using the tightening insulation jig to replace the tension-resistant porcelain insulator with electricity is that when replacing the insulator on the 66KV transmission line, the ground potential operator needs to carry the insulation transfer rope to the tower to reach the defective position of the porcelain insulator, and after fastening the safety belt, Hang the insulation transfer rope, and the ground workers will transfer the flip-mounted clamp fixture for porcelain insulators and the assembled tightening insulation fixture to the tower, and clamp the tightening insulation fixture on the right-angle hanging plate to check that it is correct Finally, pull out the spring pin with insulating rod clippers, properly tighten the screw 2, remove the lightning porcelain insulator, and replace it with a new one.
