Door shaft line-through frame with limit function of high-voltage switch cabinet

Abstract

The invention relates to the technical field of power equipment maintenance, in particular to a door shaft line-through frame with a limit function of a high-voltage switch cabinet. The door shaft line-through frame comprises a limit device and a line through device, wherein the limit device comprises a limit pulley and a horizontally disposed double-sliding rail that is fixed on the inner side wall of the door of the high-voltage switch cabinet, the limit pulley is slidably sleeved in the double-slide rail, a horizontally arranged limit rod is welded in the middle of the limit pulley; the line through device comprises a vertical line through rod with the bottom end fixed on the limit rod and a line through frame fixing rod with the top end fixed in the high-voltage switch cabinet, the upper and lower parts of the line through rod are respectively connected with horizontally arranged line through pulleys, the middle of the line through frame fixing rod is fixedly sleeved with a line through frame support, and the line through frame support is further respectively provided with arc-shaped line through frame upper rails and line through frame sliding rails. By using the door shaft line-through frame, the door harnesses may have small deformation, the through lines are short, and the cabinet door may be limited at any angle, so that a certain supporting effect is provide on the opened cabinet door to prevent the door from being deformed under long-time opening.

Description

technical field [0001] The invention relates to the technical field of power equipment maintenance, in particular to a wire-passing frame with a position-limiting door shaft of a high-voltage switch cabinet. Background technique [0002] High-voltage switchgear is a complete set of electrical equipment used in the power system. Its function is to switch, control and protect the power system during the process of power generation, transmission, distribution and power conversion. It consists of high-voltage circuit breakers, load switches, contactors, high-voltage fuses, isolating switches, grounding switches, transformers and station transformers, as well as control, measurement, protection, adjustment devices, internal connections, accessories, shells, etc. The space in the cabinet mainly uses air or composite insulating materials as the medium to receive and distribute the three-phase electric energy of the grid. [0003] When the panel surface of the measuring instrument,...
