Ground rail vehicle for fully automatic cable partial discharge test

Abstract

The invention discloses a full-automatic ground rail car for a cable partial discharge test. The full-automatic ground rail car comprises a car frame. Rail wheels walking on bottom rails are arranged on the car frame, and an initiative self-rotation roller and a passive self-rotation roller are arranged on the left and the right of the car frame in parallel. The front end of the initiative self-rotation roller and the front end of the passive self-rotation roller are connected with a front screw rod through screw rod nuts, and the rear end of the initiative self-rotation roller and the rear end of the passive self-rotation roller are connected with a rear screw rod through screw rod nuts. The front screw rod and the rear screw rod are positive and negative distance adjusting screw rods, wherein the left portions and the right portions of the positive and negative distance adjusting screw rods are opposite in spiral direction. The full-automatic ground rail car for the cable partial discharge test is reasonable in structure, capable of meeting the requirements for automatic operation and automatic plate rotation, capable of meeting the requirement for automatically adjusting the distance of two rollers of a security cable plate according to diameters of cable plates with various specifications and the requirement for safe limiting, steady in center of gravity and safe in operation. The cable plates can be stably and reasonably placed on balance points of the ground rail car and can be simultaneously opened in parallel or simultaneously closed in parallel so as to achieve use allowances of the cable plates with the various specifications.

Description

technical field [0001] The invention relates to a ground rail vehicle for partial discharge tests of cables. Background technique [0002] The existing ground rail car for partial discharge voltage withstand test of medium and high voltage power cables can only meet the functions of automatic operation and automatic turntable, but cannot meet the function of adjusting the roller distance according to the diameter of the cable reel, which limits the margin of the cable reel diameter specification and stability and safety during operation. Contents of the invention [0003] The purpose of the present invention is to provide a fully automatic cable partial discharge test site with a reasonable structure, which can not only meet the needs of automatic operation and automatic turntable, but also can automatically adjust the safety limit of the distance between the two rollers of the security cable reel according to various specifications of the cable reel. rail car.
