Embodiment 1

[0024] A 500 kV power transmission line spacer fixture, which consists of: a lead screw 1, a spacer upper clamp 2 and a spacer lower clamp 3, and the spacer rods are inserted into the lead screw near the middle position The upper card and the lower card of the spacer bar, the upper end of the lead screw is connected with the ratchet wrench 4, the circular through hole of the ratchet wrench is provided with a spacer bar ratchet fixture 5, and the spacer bar ratchet fixture 5 is arranged on the said spacer bar The card and the lower card of the spacer bar are connected with the upper and lower card positioning bars 6 of the spacer bar, and a lead screw wrench 7 is inserted in the through hole at the lower end of the lead screw.

Embodiment 2

[0026] The dismounting method of the 500 kV transmission line spacer clamp according to embodiment 1: the method comprises the following steps:

[0027] Use the ratchet wrench, spacer ratchet fixture and loose spacer bolts, and use the fixture itself as the force arm to complete the work of disassembling the spacer; The positioning rod and the lead screw wrench are screw-type spacer clamps respectively, in which the upper clamp of the spacer and the lower clamp of the spacer

[0028] They respectively represent the upper and lower clamps of the screw-type spacer bar fixture. The position is fixed by the spacer bar up and down. And tighten the arm of the spacer bar to help remove or install the pin at the arm of the spacer bar, and quickly complete the work of disassembling and assembling the spacer bar.

Abstract

The invention discloses a fixture for spacers of 500-kilovolt power transmission lines and a method for disassembling the spacers. Operational inspection and maintenance and defect elimination on the spacers which are important protective fittings for the power transmission lines are critical work for maintaining safe and stable operation of the power transmission lines, faults such as collision of conducting wires and strand breakage of the conducting wires can be possibly caused if defects of the spacers are not timely eliminated by the aid of live operation or power-off maintenance operation, and safe operation of the lines can be severely threatened. The fixture for the spacers of the 500-kilovolt power transmission lines comprises a lead screw (1), an upper spacer clamp (2) and a lower spacer clamp (3). The upper spacer clamp and the lower spacer clamp respectively sleeve the positions close to the middle of the lead screw, the upper end of the lead screw is connected with a ratchet wrench (4), a spacer ratchet fixture (5) is arranged in a circular through hole of the ratchet wrench, an upper and lower spacer clamp positioning rod (6) is arranged between the upper spacer clamp and the lower spacer clamp in a connected manner, and a lead screw wrench (7) is inserted in a through hole in the lower end of the lead screw. The fixture and the method are mainly applied to power transmission lines.

Description

[0001] The invention relates to a 500 kV power transmission line spacer fixture and disassembly method, which quickly completes the replacement of defective spacers, greatly shortens the working time of live work, and improves the work efficiency and safety performance of live work . [0002] Background technique: [0003] As an important protective fitting for transmission lines, the inspection, maintenance and elimination of spacer rods are the key tasks to maintain the safe and stable operation of transmission lines. If the defects of the spacer rods are not eliminated by live work or power-off maintenance work in time, it may cause faults such as wire whipping and wire strand breakage, which pose a serious threat to the safe operation of the line. [0004] At present, the method of removing old parts and installing new parts is used to deal with the defects of spacers. There are mainly the following two working modes: [0005] For individual defects, use live work to compl...
