Abstract
The invention provides a method for replacing optical fiber composite overhead ground wire or common overhead ground wire without power failure, a plurality of hanging pulleys and a stringing tractor are hung on the old ground wire between iron towers, the hanging pulleys and the iron tower at one end, the adjacent hanging pulleys and the stringing tractor and the hanging pulleys are fixedly connected by connecting ropes with the interval length of 15-20 m, a new ground wire is discharged from a pay-off reel arranged on the ground, passes through a hole at the lower part of each hanging pulley after passing through the top of the iron tower at the end and is connected with an insulating rope arranged on the stringing tractor by a clamp, the stringing tractor is started to pull the new ground wire to the iron tower at the other end, the stringing reaches the top of the iron tower at the other end, the old ground wire is taken down and is arranged on the pulleys of the iron towers at two ends, the new ground wire is connected to the iron tower after being stretched to a specified arc sag, the connecting rope is fixed on the other end, the old ground wire is released, the upper and lower positions of the old ground wire and the new ground wire are exchanged, the old ground wire is retracted by a take-up reel arranged on the ground, meanwhile, the connecting rope, the insulating rope, the hanging pulley and the stringing tractor are dismounted, and finally, the sag of the new ground wire is accurately adjusted, the accessory is installed, and the positioning and the reinforcing are carried out. The invention can conveniently control the arc sag of the new and old ground wires, so that the new and old ground wires can not touch the power line, thereby being capable of constructing without power failure, reducing the trouble of reporting and approval and not influencing the production and life electricity consumption of units and residents.
Description
Technical field
The present invention relates to a kind of replacing method of overhead ground wire of transmission line, especially do not have a power failure and change the method for Optical Fiber composite overhead Ground Wire or common overhead ground wire.
Background technology
The existing OPGW of transmission line of electricity or the method for common aerial earth wire changed at the old ground wire of dismounting with set up newly in the line process, can cause injury to the workmen because ground wire is touched power line easily, therefore must power cut construction.Like this, not only increase loaded down with trivial details procedure of submitting reports for approval but also can affect unit and resident's production, household electricity, brought very big inconvenience.
Summary of the invention
Deficiency for the method that overcomes the existing OPGW of changing transmission line of electricity or common aerial earth wire, solution is at the old ground wire of dismounting and set up the problem that ground wire in new the line process is touched power line easily, the invention provides a kind of the power failure and change the method for OPGW or common aerial earth wire, at the old ground wire of dismounting with set up newly in the line process, ground wire can not touched power line, thereby power cut construction not, not only reduce the declaration trouble but also can not affect unit and resident's production, household electricity.
A kind of power failure the provided by the invention changed the method for OPGW or common aerial earth wire, old ground wire between iron tower mounts a plurality of Hanging rollers and a stand line tractor, between Hanging roller and the end iron tower, between the adjacent Hanging roller, all be fixedly connected with connection cord between stringing tractor and the Hanging roller, gap length is 15 meters-20 meters, new ground wire is emitted through passing the hole of each Hanging roller bottom behind this end iron tower top from the draw drum that is located at ground, link together with anchor clamps with the insulating cord that is located on the stringing tractor, start the stringing tractor new ground wire is pulled to other end iron tower, the stringing tractor arrives other end iron tower top, take off on the pulley that old ground wire is mounted to the two ends iron tower, be connected on the iron tower after new ground wire being stretched to the sag degree of regulation, again that connection cord is fixing at other end iron tower, loosen old ground wire, make old ground wire, newly ground wire is upper, upper/lower positions exchanges, regain old ground wire by the take-up reel that is located at ground, unload simultaneously connection cord, insulating cord, Hanging roller, the stringing tractor is made accurate adjustment and installation accessories to the sag degree of new ground wire at last, the location reinforces.
Adopt method of the present invention to change in the OPGW or common aerial earth wire process of transmission line of electricity, arrange that the uniform a plurality of Hanging rollers in interval can be controlled newly easily, the sag degree of old ground wire, make them can not touch power line, therefore power cut construction had not only reduced the declaration trouble but also can not affect unit and resident's production, household electricity.
