Special ground conducting wire hydraulic compression connection method for transmission line

Abstract

The invention relates to a special ground conducting wire hydraulic compression connection method for a transmission line, which comprises the following steps: (1) mounting, before compression connection, a device is well assembled, a steel channel guide rail with a fixed middle area is lay flat on a leveling ground, a hydraulic plier is placed in the steel channel guide rail, a left pulley and a right pulley are mounted on the guide rail along a guide rail groove, and fixtures are mounted on the left pulley and the right pulley; (2) calibrating; (3) a steel pipe compression connection; (4) an aluminium pipe compression connection; and (5) a protection sleeve sleeving. According to the invention, the method is advanced in construction and simple to operate, can be suitable for the application of various compression connection tubes after a horizontal mid-partition limiting aluminium pipe is adopted, has high precision for horizontally compressing and connecting butted steel connecting pipes and connecting aluminium pipes, can support and hold aluminium conducting wires per se, automatically completes the straightening of ground conducting wires, completely avoids various problems existing in the manual compression and connection, and has the advantages that the compressing connection is reliable, the precision is high and the cost is low.

Description

technical field [0001] The invention belongs to the field of electric power, and relates to the connection of a ground wire of a power transmission line, in particular to a hydraulic crimping method for a special ground wire of a power transmission line. Background technique [0002] In the construction process of overhead transmission lines, hydraulic crimping of the ground wire is widely used for the connection of the ground wire. Since the ground wire needs to be buried after connection, it is an important concealed project, which is related to the engineering quality of the transmission line and the long-term safe operation of the power grid. At present, when using the existing hydraulic device for crimping, it is necessary to manually support the wire, and determine the level of the wire according to the feel, so the quality of the straightening cannot be guaranteed, and the problem of straightening with a manual mallet has to be used, which not only affects the work ef...
