Devices for securing grounding cables

Abstract

The invention discloses a device for fixing grounding cables, which belongs to the technical field of electric appliances, and comprises a main hoop matched with the main cable and a secondary hoop matched with the grounding cable. The main hoop and the sub hoop are connected through a The device is connected; the main hoop includes an upper hoop body and a lower hoop body that are mated and connected together, and the main hoop is provided with a wire hole that cooperates with the main cable; the secondary hoop includes an upper hoop that is mated and connected together The hoop piece and the lower hoop piece, and the secondary hoop is provided with a threading hole for matching with the grounding cable. The device for fixing the grounding cable provided by the present invention has a simple overall structure and a reasonable design. The grounding cable is connected to the main cable through the main hoop, the secondary hoop and the connecting device, which greatly improves the installation stability of the grounding cable. A spring is set on the connecting rod, and the spring has the characteristic of automatic recovery, which can eliminate the thermal creep between the main hoop and the auxiliary hoop, and realize a flexible connection between the auxiliary hoop and the main hoop.

Description

technical field [0001] The invention relates to the technical field of electric appliances, in particular to a device for fixing grounding cables. Background technique [0002] With the development of social economy, in order to improve the power supply quality of the power grid, improve the environmental conditions, and make effective use of land resources, more overhead lines have been transformed into power cables. During the transformation and construction, a large number of terminal towers were added, and the increase of terminal towers put forward different requirements for operation, maintenance and overhaul. The fixing of the grounding cable in the existing cable terminal tower is usually directly wound on the main cable with adhesive tape. Due to natural reasons and the quality of the fixing tape, the adhesive tape for fixing the grounding cable will be damaged or broken, causing the grounding cable to be separated from the main cable. Hanging in the hole or on the...

The fixing of the grounding cable in the existing cable terminal tower is usually directly wrapped on the main cable by adhesive tape. Due to natural reasons and the quality of the fixing tape, the tape for fixing the grounding cable will be damaged or broken, causing the grounding cable to be separated from the main cable. Hanging in the hole or on the terminal tower will bring safety hazards to the operation of the power cable and fail to meet the requirements of the power construction process

At the same time, the workload of maintenance operations is increased, and the economic waste caused is relatively large
