Cable fixing clamp and cable fixing device employing cable fixing clamp

Abstract

The invention relates to a cable fixing device, which comprises an adjustable mounting rack capable of adjusting high, low, front and rear positions of cable fixing clamps and at least one cable fixing clamp which is fixedly arranged on the adjustable mounting rack, wherein each cable fixing clamp comprises a clamping seat used for clamping a cable through a locking device after the alignment of the cable and a clamping cover; clamping through slots for clamping the cable are formed in the clamping seats; hollow cavities are respectively formed in two side walls of the clamping through slots; clamping bulges which can be inserted into the corresponding hollow cavities when the clamping covers and the clamping seats are aligned are arranged on aligned end faces of the clamping covers; and cable clamping surfaces on the clamping bulges and the clamping through slots on the clamping seats form cable clamping space of which the size is changed along with change of the alignment depth of the clamping covers and the clamping seats. By the cable fixing device, the stress of mechanical fastening on the cable can be reduced, the cable mounting reliability is improved, faults of cable heads are reduced, and the same cable fixing clamp can be matched with cables of different wire diameters. The invention also relates to a cable fixing clamp.

Description

technical field [0001] The invention relates to a cable fixing clip and a cable fixing device which can be used in a high-voltage switch cabinet to clamp and fix cables. Background technique [0002] After the high-voltage switchgear and cables are laid, in order to make it a continuous power supply line, it is necessary to use the plug-in cable head to complete the connection and fixation of the cable and the bushing. At present, two fixed points are generally set before the cable phase separation and at the cable head to implement cable fixing, and when fixing, the installation technicians often rely on the experience of the installation technician to obtain materials on the spot and carry out mechanical fixing, which is neither reliable nor satisfactory for the production of the cable head. Strict process requirements in the process. In addition, due to the weight of the cable and the electric force, the cable head will be stressed, or the cable length error will cause b...

At present, two fixed points are generally set before the cable phase separation and at the cable head to implement cable fixing, and when fixing, the installation technicians often rely on the experience of the installation technician to obtain materials on the spot and carry out mechanical fixing, which is neither reliable nor satisfactory for the production of the cable head. Strict process requirements in the process

In addition, due to the weight of the cable and the electric force, the cable head will be stressed, or the cable length error will cause bending stress to the cable head after the cable is phase-separated, which will affect the insulation performance of the bushing and the cable head, resulting in power supply failure. The installation performance of electrical equipment directly affects the reliability and stability of the power supply system

[0003] Chinese patent document CN202302322U discloses a cable fixing clip, which includes a clip seat and a clip cover that are connected by fastening bolts to clamp the cable after movable docking. Finally, it forms a cylindrical clamping cable. This structure is only suitable for clamping cables with fixed wire diameter specifications or cables with a small diameter range. For cables with slightly larger or smaller diameters, the clamping is not tight and cannot Reliable fixing of cables
