Extra-high voltage line quadruple end insulator replacement fixture and use method thereof

Abstract

The invention relates to the technical field of electric power instruments, in particular to an extra-high voltage line quadruple end insulator replacement fixture and a using method thereof. The extra-high voltage line quadruple end insulator replacement fixture comprises two end U-shaped clamping plates, two length adjusting yoke plates and a contraction assembly, the two end U-shaped clamping plates are parallel, the two length adjusting yoke plates are both connected between the two end U-shaped clamping plates, the two length adjusting yoke plates are connected to two side plates of the end U-shaped clamping plates respectively, connecting holes in the upper ends of the two length adjusting yoke plates are connected with two lead screws of the contraction assembly respectively, and the line triangular yoke plate is connected between the two end U-shaped clamping plates. A right-angled hanging plate at the lower end of the first insulator at the cross arm end to be replaced is connected into a bottom plate notch of the U-shaped clamping plate at the end part; the fixture is simple in structure, easy to machine, convenient and fast to assemble, light in weight, convenient to carry, and capable of simplifying the operation process, saving tools and instruments, reducing labor intensity and improving maintenance operation efficiency.

Description

Technical field [0001] The present invention relates to the field of power instruments, specifically a special high voltage line four end portion insulator replacement cartridge and its use thereof, is particularly suitable for replacement of the insulator of the four end portion of 750 kV and ± 800 kV high voltage line. Background technique [0002] The ultra-special high-pressure transmission line end card is a metal cartridge when replacing the glass or porcelain insulator during transmission line. When using the end card, the end card is on the triangular plate, and the other end card is replaced. On the insulators in the insulator in the insulator, the tightening screw will transfer the load on the insulator to the card, thereby replacing the insulator. In the replacement operation of the insulator, due to the model and type of the insulator, the number of tower and the angle is different, and the conventional cartrust and insulator size are not supporting, different voltage...

AI Technical Summary

Problems solved by technology

In the replacement of insulators, due to the many types and types of insulators, the tower type and the angle of rotation are different, the conventional clamps do not match the size of the insulators, and different voltage levels and different tensile sections require specific clamps. At present, there is no fixture suitable for different voltage levels and different tensile angles to replace the end insulators, which makes the operation more difficult and the number of tools increases.
