Abstract

The invention discloses a high-voltage pothead lineation cutting positioning method. The method comprises the steps that the front end face of a positioning block at the end of a main ruler clamping jaw of a high-voltage pothead lineation cutting positioning device is made to be aligned to the end face of a high-voltage cable to be cut, an auxiliary ruler clamping ring is clamped to the external circle of the high-voltage cable, an auxiliary ruler is moved to the required lineation size L1, a first lineation cutting positioning auxiliary device is installed, the right end face of the first lineation cutting positioning auxiliary device is made to be aligned to the left end face of the auxiliary ruler, a screw is locked, and the position of the lineation position L1 is determined; the steps are operated repeatedly, and then the positions of lineation positions L2, L3, L4, L5...Ln are determined; a lineation tool is used for conducting lineation on the external circle of the high-voltage cable in sequence at last, corresponding positions of L1 to Ln sizes are determined, and materials which need to be peeled off are cut and peeled off layer by layer. The high-voltage pothead lineation cutting positioning method achieves lineation positioning at a time, the precision reaches 0.02mm, and cable sheathes, steel belt steel armors, copper shield layers, conducting shells, main cable insulation layers and the like are peeled off layer by layer according to the lineation positions.

Description

technical field

[0001] The invention relates to a method for scribing, cutting and positioning a high-voltage cable head. Background technique

[0002] The high-voltage cable head is peeled off in layers such as the cable sheath, steel tape armor, copper shielding layer, semi-conductive layer, and cable main insulation layer. The stripped size must be accurate to the millimeter level, or even higher. In the cable terminal assembly, the crimping part of the outlet terminal, the cover cap, the terminal insulation body, the insulation tube, the winding part of the self-adhesive tape of the semi-conductive layer, the fixing of the constant force spring hoop, the fixing of the copper braid, and the three sets of sleeves are accurate according to different positions. When correctly installed on the high voltage cable head. At present, the measurement of the cable head on site is to measure a section with a tape measure, peel off a section, and install a part, which brings difficu...

Embodiment Construction

[0018] figure 1 1-6 represent the six layers of high-voltage cables. L1 is the length of the first section to be removed, L2 is the length of the second section to be removed, L3 is the length of the third section to be removed, L4 is the length of the fourth section to be removed, L5 is the length of the fifth section to be removed, L6 is the sixth length to be resected. In order to complete the layered cutting of the above six sections, at present, a tape measure is used to measure one section, and one section is cut off. The present invention can complete the scribing of the above-mentioned multi-layer cutting positions at one time.

[0019] A high-voltage cable head scribing cutting positioning method, the right end face of the main ruler claw end positioning block of the high-voltage cable head scribing and cutting positioner is facing it with the end of the high-voltage cable to be cut, and the auxiliary ruler snap ring is clamped on the high-voltage cable On the outer...
