Embodiment Construction

[0031] This embodiment is the replacement of the upper two insulator strings in the quadruple insulator string:

[0032] The method for replacing the tension insulator string of the high-voltage transmission line with live rotation on the present invention comprises the following steps:

[0033] ①Use the spark gap detector to test the zero-value insulators of the four strings of insulators to ensure that there are more than 23 good insulators, and it is determined that the insulator strings need to be replaced; On the side of the tension clamp, remove the pressure equalizing ring on the side of the insulator to be replaced, and fix the wing clamp through the two screw holes vacated by the front clamp at the end of the wing;

[0034] Another operator installs the rear clip of the wing-shaped end on the traction plate in front of the adjustment plate;

[0035] ②The front card of the wing-shaped end and the rear card of the wing-shaped end are connected by two sets of insulating...

Abstract

The invention discloses a method and a two-connection board device for replacing tension insulator strings of high-voltage transmission lines with upspinning and charging. The insulator strings are loosened first by using special tools such as end wing clips and insulating pull plates; The pulleys and screw rods on the side make all the ends of the insulator strings disengage; finally, the pulleys on the ground wire brackets are used to rotate the porcelain bottle strings from the horizontal state to the vertical state, thus changing the complex operation into a relatively simple operation, which greatly shortens the time Potential working time to ensure the safe operation of the line; live replacement of the high-voltage transmission line tension insulator string double-connected plate device, including two wing cards and two screw screws, and also includes two pairs of insulating pull plates, one end of the two pairs of insulating pull plates They are respectively connected with two wings of the wing card, and the other ends are respectively connected with a lead screw, and the other ends of the two lead screws are respectively connected with the two wings of the other wing card. The structure is simple, easy to operate and low in cost.

Description

technical field [0001] The invention relates to a method and device for replacing insulator strings of a high-voltage transmission line, in particular to a method for replacing a tension insulator string of a high-voltage transmission line with upswing and live charging and a two-plate device. Background technique [0002] In the overhead high-voltage transmission line, when the high-voltage wires pass through the two ends of the iron tower, the high-voltage wires near the two sides of the iron tower are usually tensioned and connected to the cross-arm of the iron tower with tension insulator strings. Connection, thereby ensuring the normal connection of the wires and high-voltage power transmission, and the high-voltage wires on both sides of the tower are tensioned and insulated through the insulator string. Tension insulator strings will be aged and damaged after long-term use, and need to be replaced in time, otherwise it will affect high-voltage power transmission and s...
