Problems solved by technology

The grounding wire terminal card is a part connected with the maintenance line to be repaired. It is usually used in conjunction with the grounding rod to complete the safe conduction work. The existing grounding wire terminal card used in conjunction with the grounding rod cannot be used according to Adaptive adjustments are made for specific use occasions, such as height adjustment, tilt angle adjustment, etc. At the same time, the overall structural positioning is not reliable and there is a hidden danger of detaching from the busbar, which can no longer meet the safe and efficient maintenance requirements of the existing high-voltage lines. what needs to be solved

Abstract

The invention belongs to the technical field of high-voltage circuit maintenance and application, and particularly discloses a wire end clamp of a multifunctional busbar grounding wire. The wire end clamp comprises a connection adjustment assembly and a wire end clamp assembly, wherein the wire end clamp assembly is used with the connection adjustment assembly in a matching way. The wire end clampof the multifunctional busbar grounding wire has the beneficial effects of reasonable design structure, adaptive and accurate lifting adjustment can be performed according to an actual application demand by the connection adjustment assembly and the wire end clamp assembly which are used in a matching way, adaptive stable and high-efficient angle adjustment also can be performed according to theactual application demand, positioning is reliable after adjustment, meanwhile, the wire end clamp is tightly assembled, connected and positioned with a busbar, and the wire end clamp is safe to use.

Description

technical field [0001] The invention belongs to the technical field of overhaul and maintenance application of high-voltage lines, and in particular relates to a multi-functional busbar ground wire terminal card. Background technique [0002] High-voltage lines usually refer to transmission lines that carry voltages above 10KV (including 10KV). According to GB / T 2900.50-2008, definition 2.1 stipulates that high voltage usually does not contain 1000V. The voltage levels of China's domestic high-voltage transmission lines are generally divided into: 35KV, 110KV, 220KV, 330KV, 500KV, 750KV, etc. [0003] In the daily maintenance of high-voltage lines, it is necessary to perform grounding protection processing actions to ensure the safety of operators. The grounding wire terminal card is a part connected with the maintenance line to be repaired. It is usually used in conjunction with the grounding rod to complete the safe conduction work. The existing grounding wire terminal c...
