Abstract

The invention discloses a method for constructing a blocking protection device of a quad-bundle conductor. The method comprises the steps of placing a first old conductor, a second old conductor, a third old conductor and a fourth old conductor of the quad-bundle conductor in a first containing groove, a second containing groove, a third containing groove and a fourth containing groove of a paying-off tackle respectively, wherein the first containing groove, the second containing groove, the third containing groove and the fourth containing groove are sequentially distributed from left to right; fixing a plurality of blocking protection devices on the first old conductor and the fourth old conductor at intervals; replacing the second old conductor with a first new conductor, and replacingthe third old conductor with a second new conductor; and exchanging the first new conductor and the first old conductor, and after the second new conductor and the fourth old conductor are exchanged,fixing the plurality of blocking protection devices on the exchanged first new conductor and second new conductor at intervals so as to construct the blocking protection devices, so that the technicalproblem that the blocking protection devices are difficult to build when the terrain is uneven is solved.

Description

technical field [0001] The application belongs to the technical field of power grid equipment, and in particular relates to a method for building a four-split conductor network sealing protection device. Background technique [0002] The four-split conductors in the existing power grid will be aged or damaged, resulting in defective conductors. When defective conductors appear, the defective conductors need to be replaced to ensure normal power transmission. [0003] Since the bad wire crosses the ground object, in order to prevent the bad wire from falling and smashing the ground object during the replacement process, it is necessary to build a sealing protection device above the ground object to protect the ground object. However, when the terrain is uneven, it is difficult to construct the network blocking protection device. Contents of the invention [0004] In view of this, the present application provides a method for constructing a four-split conductor network seal...
