A high-voltage cable intermediate joint protection device based on physical restraint

Abstract

The invention discloses a high-voltage cable intermediate joint protective device based on physical restraint, its structure includes high voltage cable, protective device, Conductor at connected end,shield is provided by a restraining tube, clamping mechanism, Protective tube, arc closure plate, A table-shaped pipe fitting is compose of, Install the restraint tube at the connection point of thetwo high-voltage cables, 4 arc-shaped closure plate are bound by a circular mesa-shaped pipe to form a circular structure in a sealed state, stop the infiltration of rainwater, Arc-shaped closure plate are positioned and mount through positioners, so that the entire guard does not fall off, As that conductor at the connected end is held by the clamping mechanism, so as to avoid frictional damage caused by sloshing, so as to prolong the service life, and when the conductor at the connecting end is pulled to both ends, the barb on the pressing rod is stuck on the skin of the conductor at the connecting end, so that the semi-circular pressing plate more tightly clamps the conductor at the connecting end, and the energization of the conductor at the connecting end is not affected.

Description

technical field [0001] The invention relates to the field of high-voltage cables, in particular to a protective device for intermediate joints of high-voltage cables based on physical constraints. Background technique [0002] Many large-scale equipment now require high-voltage cables to conduct electricity. There are two installation modes for high-voltage cables, one is buried underground and the other is on the surface. As for the high-voltage cables on the surface, they are often damaged by various factors. The high-voltage cables on the tower crane generally require a large length, but some high-voltage cables are not long enough to connect and install two high-voltage cables. The high-voltage cables are suspended on the tower crane for a long time, so they are often affected by the work of the tower crane, and the connection between the two high-voltage cables will be damaged by friction or soaking in rainy days, which may lead to leakage and short circuit after a long...

As for the high-voltage cables on the surface, they are often damaged by various factors. The high-voltage cables on the tower crane generally require a large length, but some high-voltage cables are not long enough to connect and install two high-voltage cables. The high-voltage cables are suspended on the tower crane for a long time, so they are often affected by the work of the tower crane, and the connection between the two high-voltage cables will be damaged by friction or soaking in rainy days, which may lead to leakage and short circuit after a long time situation, greatly increasing the danger of construction workers working on the tower crane
