Problems solved by technology

[0002] After laying cables, especially cables with large cross-sections, due to thermal stress and other reasons in the process of manufacturing and operation, there will be a lot of thermomechanical stress and slippage, and a lot of electromotive force will be generated under abnormal conditions such as short circuit. , these forces will cause damage to the cable to a certain extent if no measures are taken to deal with them, resulting in cable line failure

Abstract

The invention belongs to the field of electrical equipment, and relates to a sliding high voltage cable floating combination fixing device which comprises a lower plate component and an upper plate component connected to the surface of the upper portion of the lower plate component. A cable clamp is fixed on the top face of the upper plate component. The lower plate component comprises a bottom plate, a lower guide rail arranged on one side of the surface of the bottom plate, and a lower connection seat arranged on the other side of the surface of the bottom plate. The upper plate component comprises a top plate, an upper guide rail arranged on one side of the bottom face of the top plate, and an upper connection seat arranged on the other side of the bottom face of the top plate. The sliding high voltage cable floating combination fixing device is reliable in effect, when the sliding high voltage cable floating combination fixing device is used, cable moving can be limited in the vertical direction, and disorderly deviation can not occur; meanwhile, due to the effect of a spring, when a cable ascends through thermal stress, spring force can effectively counteracts the weight of the upper plate component, and resistance of the cable in the ascending process can not be increased.

Description

technical field [0001] The invention belongs to the field of electrical equipment and relates to a slidable high-voltage cable floating combined fixing device. Background technique [0002] After laying cables, especially cables with large cross-sections, due to thermal stress and other reasons in the process of manufacturing and operation, there will be a lot of thermomechanical stress and slippage, and a lot of electromotive force will be generated under abnormal conditions such as short circuit. If these forces do not take measures to deal with, they will cause damage to the cable to a certain extent, resulting in cable line failure. In order to ensure that cables, especially large-section cables, are not damaged by these mechanical forces, it is necessary to have a device that releases thermal stress longitudinally, can slide laterally, and can be fixed axially to prevent electrodynamic damage. Contents of the invention [0003] The purpose of the present invention is...
