A live installation and removal method and installer for an overhead line phase sequence plate

Abstract

The invention relates to an overhead line phase sequence plate hot-line assembly and disassembly method and an assembling device, and belongs to the technical field of power supply maintenance and construction. According to the technical scheme, the assembling device comprises side baffles (1), a main substrate (2) and a connector (3), the main substrate is a square insulating board, the side baffles are arranged on three edges of the obverse side of the main substrate and are integrally of a U type, each U-type side baffle is open upwards, the side baffles are also insulating boards and are bonded to the main substrate through vertical boards (4), a gap is reserved between each side baffle and the main substrate, the thickness of each gap is equal to the height of the corresponding vertical board, a slot (5) is formed by the side baffles, the main substrate and the vertical boards, and the connector is arranged on the reverse side of the main substrate. The assembling device is simple in structure, flexible in use and capable of conveniently assembling or disassembling phase sequence plates, the problem that operating personnel need to ascend is solved, labor intensity is relieved, the insulating effect is achieved, safety is guaranteed, the line outage frequency is reduced, and the power supply reliability rate is guaranteed.

Description

technical field [0001] The invention relates to a live installation and removal method and an installer for a phase sequence plate of an overhead line, belonging to the technical fields of power supply maintenance and construction. Background technique [0002] At present, the current line pole number plates are mainly made of enamel. During installation, iron wires need to be threaded on the phase sequence plates, manually mounted on the poles, and bound to the crossarms of overhead line pole towers. The background technology has the following problems: ①The iron wire has been eroded by wind and rain for a long time, and it is easy to rust and break, resulting in the loss of the phase sequence plate or hurting pedestrians when it falls; ②The joints of the iron wire are easy to scratch the climbers and clothing; ③ If the iron wire is too long, it is easy to cause hidden dangers and threaten the safe operation of the line; ④ When personnel install or remove the pole, the line...
