Summary of the invention
The present invention existingly changes the problem that in overhead ground wire thread-changing construction, the engineering time is long, required personnel are many, investment is huge for solving, and then proposes to utilize the hanging of PPR pipe to carry out high voltage overhead power transmission sequence replacing overhead ground wire device and method.
The present invention addresses the above problem the technical scheme of taking to be: device of the present invention comprises two PPR pipes, two insulating cords and four drill rod earth anchors, the middle part of every insulating cord is set with respectively a PPR pipe, and often the end with insulating cord respectively is connected with a drill rod earth anchor respectively.
The concrete steps of the method for the invention are as follows:
Step 1, crossed over thing both sides above parallel wire on respectively hang respectively a PPR pipe;
The two ends of step 2, every insulating cord of traction make two PPR pipes parallel;
Step 3, with the tension of every insulating cord, and will every the drill rod earth anchor at insulating cord two ends ram ground, each drill rod earth anchor is apart from being 10 meters by the distance of leap thing;
The replacing of namely completing overhead ground wire after thing both sides shaft tower wire clamp installs is crossed in step 4, the unwrapping wire that carries out overhead ground wire on two PPR pipes and stringing operation;
Step 5, will change the overhead ground wire device and remove.
The invention has the beneficial effects as follows: using the present invention to change overhead ground wire only needs two people to get final product, and has reduced labour's input, has saved the engineering time, and the present invention is simple in structure, and is easy to operate, and fund input is few, has saved a large amount of costs; Reduced the resident living that causes because of long-time power failure constant, and factory and enterprise etc. is with the economic loss of electric unit, can also improve the power supply reliability of power supply enterprise, when also having reduced simultaneously because of construction to trip and the security implication of the traffic routes such as highway, railway.
