Problems solved by technology

[0002] When the generally known GW5 type isolating switch is overhauled, if the porcelain sleeve is pulled down without a crane, it is mostly to use a pole and a pulley. A rope is inserted into the pulley, and one end of the rope is tied on the isolating switch. One end is held by many people, and the isolating switch is dragged to the equipment frame by manpower, which not only consumes manpower and material resources, but also cannot guarantee the safety of people and equipment; Due to the influence of the range and the weather, it is difficult to meet the conditions for maintenance, which is a long-standing problem in the power system

Embodiment Construction

[0013] When hoisting the V-shaped support porcelain bottle on the GW5-110 kV high-voltage isolation switch, the operation method is as follows:

[0014] Electrical workers, fix the base of the hanger firmly with J-shaped bolts, insert the hanger into the socket of the base, adjust the direction, fix the hanger with a wire tightener, hang the chain hoist, and put the bottle hanger Place it on the support porcelain bottle for fixing, hang the bottle holder on the chain hoist with a wire rope, and lift the V-shaped support porcelain bottle, you can lift the isolating switch as a whole, and you can also disassemble the isolating switch support and the porcelain bottle to achieve Supports and bearings for replacement and overhaul purposes.

Abstract

The invention relates to repair hoisting device and method for an isolating switch. The hoisting device which is suitable for repairing and replacing a GW5 isolating switch comprises a tightener (1),a manual hoist (2), a base (3), a hanging rod (4) and a bottle hanging rack (5). The hanging rod and the bottle hanging rack are designed and manufactured according to the height and the weight of theGW5 isolating switch and the geometric dimension of a supporting insulator so as to ensure that the isolating switch and a china bottle are reliably hoisted and a mounting angle of the china bottle is unchanged, and the base is designed and manufactured according to the mounting principle of the GW5 isolating switch so that the base is convenient and rapid to disassemble and assemble, practical and reliable.

Description

technical field [0001] The invention relates to a lifting device and a method for overhauling a GW5 type isolating switch on 110 kV high-voltage equipment in a power system. Background technique [0002] When the generally known GW5 type isolating switch is overhauled, if the porcelain sleeve is pulled down without a crane, it is mostly to use a pole and a pulley. A rope is inserted into the pulley, and one end of the rope is tied on the isolating switch. One end is held by many people, and the isolating switch is dragged to the equipment frame by manpower, which not only consumes manpower and material resources, but also cannot guarantee the safety of people and equipment; Due to the influence of the scope and weather, it is difficult to meet the conditions for maintenance, which is a long-standing problem in the power system. Contents of the invention [0003] According to the principle of "repair must be repaired" according to the dismantling and replacement. Aiming a...
