Problems solved by technology

[0003] At present, the tools used for stripping and cutting high-voltage cables are all cutting the cables as a whole; if there is no ready-made tool for partial stripping and cutting of high-voltage cables, manual methods are generally used, and the stripping process is limited by the working environment and human factors. It often causes irregular cuts, too deep cuts to damage the main insulation of the cable and affect the operation of the cable. For cables with different diameters, different stripping tools are required for local stripping.

Embodiment 1

[0023] Such as Figures 1 to 3 Shown is embodiment 1 of a high-voltage cable local stripping and cutting device of the present invention. A high-voltage cable local stripping and cutting device includes a fixing part 3, a fixing belt 4, a cutting device and a driving motor. Both ends of the fixing belt 4 are fixed on the fixing part 3, and the cutting device is detachably connected to the fixing part 3.

[0024] Among them, the fixing part 3 is provided with a slitting tool fixing position and a ring cutting tool fixing position 7, and the top of the fixing part 3 is provided with a slitting slit. When the cutting device is installed on the slitting tool fixing position, the fixed part is fixed. The cable body is longitudinally cut, and when the cutting device is installed on the ring cutting tool fixing position 7, the cable body 5 fixed by the fixing member 3 is circumferentially cut. Cutting device comprises cutter 9, cutter protection cover 2 and handle 1, and cutter prot...

Embodiment 2

[0028] Such as Figure 2 to Figure 3 Shown is an embodiment 2 of a method for partial stripping and cutting of a high-voltage cable of the present invention. A method for partial stripping and cutting of high-voltage cables. Before stripping and cutting, the stripping position of the cable body is determined, and the cable body 5 at this position is mechanically straightened. The straightening length is 1m; first, the stripping device is fixed on the straightening On the outer sheath 10 of one end of the cable main body, the cutting device is installed on the ring cutting tool fixing position 7 of the fixture 3, the drive motor is started, the outer sheath 10 of the cable main body 5 is ring cut, and the cable main body 5 is cut off. Move the fixing device to the outer sheath of the cable main body at 550mm, use the cutting device to cut off the outer sheath 10 of the cable main body 5 in a circular direction, and then install the cutting device on the fixing part 3 vertically...

Abstract

The invention provides a local stripping and cutting device for a high-voltage cable. The local stripping and cutting device for the high-voltage cable comprises a cable main body, a fixing device, adriving motor and a cutting device; the fixing device fixes the cable main body; the cutting device is detachably installed at the top of the fixing device; and the driving motor is connected with thecutting device. The invention further provides a local stripping and cutting method for a high-voltage cable. According to the local stripping and cutting device and method for the high-voltage cableof the invention, the fixing piece and the cutting device can be matched with each other, so that the positioning of the cutting device on the fixing device can be changed; annual cutting and longitudinal cutting can be conducted on the cable on the fixing piece; layered stripping and cutting can be conducted on the cable; it is guaranteed that the notch of the cable is smooth in a stripping andcutting process; and conductors in the cable are not damaged.

Description

technical field [0001] The invention relates to the technical field of cable stripping and cutting, and more specifically, to a high-voltage cable local stripping and cutting device and method thereof. Background technique [0002] A high-voltage cable usually includes a 9-layer structure, including a conductor, a semi-conductive nylon tape, an inner semi-conductive layer, an insulating layer, an insulating shielding layer, a semi-conductive buffer layer, a corrugated aluminum sheath, an outer sheath layer, and a graphite layer. Among them, the conductor, semi-conductive nylon tape, inner semi-conductive layer, and insulating shielding layer belong to the key structures of electrical performance, and the rest are non-electrical performance-critical structures. When installing or maintaining high-voltage cables, it is usually necessary to strip and cut the non-electrical performance critical structures of the cables. [0003] At present, the tools used for stripping and cutt...
