Embodiment Construction

[0012] The implementation of the present invention will be described in further detail below in conjunction with the accompanying drawings. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0013] A high-voltage cable outer sheath shielding layer stripping knife, such as figure 1 As shown, it consists of two parts, the shell 1 and the knife rest group. The said knife rest group includes cylindrical handles 4 placed coaxially on both sides, and a knife rest plate 5 perpendicular to the handle is fixed at the opposite ends of the two handles. An I-shaped knife rest 8 with a groove inside is fixed between the knife rest plates parallel to each other. The rectangular sheet blade 9 is installed in the groove of the I-shaped knife rest, and passes The blade fixing bolt 7 fixes the blade, and a fixed shell bolt hole 6 is formed on both sides of the handle of the knife rest plate. Handle hole groove 3, s...

Abstract

The invention relates to a high-voltage cable outer sheath shielding layer stripping knife, which is composed of a shell and a knife holder group. The knife holder group includes cylindrical handles on both sides. There is an I-shaped knife holder with a groove inside fixed between the knife holder plates. The rectangular blade is installed in the groove of the I-shaped knife holder, and the blade is fixed by a fixing bolt. Shell bolt holes, the shell is a cuboid shell with an opening at the bottom, handle hole slots are formed on the left and right side walls of the shell, and shell bolts are installed on both sides of the handle hole slots, and the shell bolts pass through the tool holder plate. Housing bolt holes secure the housing to the tool holder plate. The invention is easy to carry, safe and quick to operate, and any novice can independently complete the stripping of the outer shield, which greatly improves the efficiency of the outer sheath test and the installation of cable accessories, and improves the safety of installation and construction personnel.

Description

technical field [0001] The invention belongs to the technical field of test operation tools for outer sheaths of cables, in particular to a high-voltage cable outer sheath shielding layer stripping knife. Background technique [0002] High-voltage cables must be tested for outer sheath resistance or outer sheath withstand voltage (D.C. 10KV / min) before construction. The first step of the test is to suspend both ends of the cable and scrape off the outer shield with a length of about 20cm. The treated outer sheath must be clean and free of semi-conductive material residues. At present, there is no very handy tool for stripping the shielding layer of the cable outer sheath. The stripping time is long and there are semi-conductive materials remaining, which will affect the resistance of the outer sheath or The pressure test of the sleeve was carried out smoothly. At present, the traditional method is to use glass sheets to scrape and shield, but if the glass is too thin, it wi...
