Extra-high voltage cable stress cone jacking device

Abstract

The invention discloses an extra-high-voltage cable stress cone jacking device, and relates to the technical field of high-voltage cable stress cones, the extra-high-voltage cable stress cone jacking device comprises a stress cone body, a base is arranged below the stress cone body, a clamping mechanism is arranged above the base of the stress cone body, and a dust collection mechanism is arranged on one side of the clamping mechanism. The clamping mechanism comprises connecting blocks, sliding rods and clamping strips, the connecting blocks are arranged on the two sides of the stress cone body, the sliding rods are fixedly installed on the outer walls of one sides of the connecting blocks, and the outer walls of the sliding rods are movably connected with the inner wall of the base. Under the interaction of a pulling plate, a connecting block, a sliding rod, clamping strips, a first spring, an L-shaped plate, an L-shaped block, a threaded rod, a clamping block and a springback assembly, a stress cone body is fixed through the springback assembly on the clamping strips, meanwhile, a rotary knob is rotated to drive the threaded rod to rotate, the threaded rod drives the clamping block on the sliding plate to be clamped into a clamping groove, the two clamping strips are locked, and therefore the stress cone body is fixed. And the fixing is convenient.

Description

technical field [0001] The invention relates to the technical field of high-voltage cable stress cones, in particular to an ultra-high-voltage cable stress cone top-tightening device. Background technique [0002] High-voltage cable is a kind of power cable. It refers to the power cable used to transmit between 1kv and 1000kv. A radially distributed electric field is formed between the core and the metal sheath, that is to say, the electric field of a normal cable has only the electric field power line from the core to the grounding metal sheath along the radius, and there is no electric field electric field power line in the axial direction of the core wire, and the electric field distribution is uniform. , When the cable head is used to connect the two sections of the cable, the original electric field distribution of the cable is changed due to the stripping of the insulation and shielding layers, which will generate a tangential electric field (power line along the axis ...

AI Technical Summary

Problems solved by technology

[0004] 1. The fixation of the existing UHV cable stress cone tightening device is not firm enough. During the long-term operation of the UHV cable, the stress cone may become loose and eccentric, resulting in a decrease in the effect of the stress cone and failure of the cable joint;

[0005] 2. The existing UHV cable stress cone tightening device is inconvenient for cleaning dust, because there is static electricity around the UHV cable, it is easier to absorb dust, and the dust is inconvenient to handle
