Abstract

The invention discloses a potential inlet seat ladder for an ultra-high voltage power transmission line, which comprises a potential seat ladder, two square plugging grooves, two square plugging blocks and two extension ladders, and is characterized in that the two square plugging grooves are respectively formed in the front side and the rear side of the potential seat ladder. According to the invention, the potential seat ladder, the square plugging groove, the square plugging block, an extension ladder, a propulsion mechanism, a threaded groove, a threaded rod, a rotating handle, an annular limiting block, an annular limiting groove, a first supporting block, a matching groove, a positioning hole, a matching block, a circular groove, a clamping mechanism, a circular baffle block, a circular positioning block, an extrusion block, an extrusion spring, a second supporting block, a sliding groove, a sliding block, positioning columns and circular matching holes are arranged and cooperatively used, the problem that the corresponding use length cannot be adjusted according to different use lengths in the prior art is solved, and the potential inlet seat ladder for the ultra-high-voltage power transmission line has the advantage of being good in adjusting effect. The potential inlet seat ladder is suitable for power transmission lines.

Description

technical field [0001] The invention belongs to the technical field of high-voltage electricity, and in particular relates to a potential-incoming ladder used for extra-high voltage transmission lines. Background technique [0002] In order to meet the market demand, the high-voltage transmission line entry potential ladder is generally optimized in terms of better insulation and more user-friendly use, often ignoring whether it can be adjusted according to different lengths in a good way. The length of the high-voltage transmission line entry potential ladder has the benefits of better insulation and more user-friendly use, but there are certain restrictions. In normal use, the distance between different high-voltage transmission lines is often different. Similarly, the current ladders are all spliced ​​together, which is heavy for the builders to carry, and at the same time it is easy to cause the problem of insufficient distance or too long distance. The problem in the pr...
