Reversible operating mechanism for isolating switch

Abstract

The invention relates to a reversible operating mechanism for an isolating switch. The reversible operating mechanism comprises a box, a manual transmission unit installed in the box, a mechanical transmission unit installed in the box, and a reversing unit installed at the upper end of the box. The reversing unit comprises a base. A round through hole is formed in the middle of the base. A crankshaft is installed in the round through hole and comprises a cylindrical embedding section located at the lower end, and an L-shaped connecting section located at the upper end. The embedding section is embedded into the round through hole in the base, the bottom end of the embedding section is connected with a transmission connecting rod through a key, and a universal joint is connected to the upper end of the connecting section. The outer end of the universal joint is sleeved with a rotating frame. The universal joint and the rotating frame are fixedly connected through a hinge pin. The rotating frame is connected with a transmission shaft of the isolating switch. The reversible operating mechanism has the advantages that by means of the reversible property of the mechanism, the installing modes of the isolating switch are diversified, and multiple shaft outputting and installing modes such as shaft outputting from the upper portion, shaft outputting from the left side and shaft outputting from the right side of the operating mechanism are achieved.

Description

technical field [0001] The invention relates to an isolating switch, in particular to a reversible operating mechanism for the isolating switch. Background technique [0002] At present, with the rapid development of the power system, the scale of Nantong Power Grid is also expanding, and the number of equipment has increased significantly. Among all the electrical equipment, the isolating switch equipment is the most, and each isolating switch needs to be equipped with at least one operating mechanism, and the number of mechanisms is often one to twice that of the isolating switch. [0003] At present, the operating mechanisms at home and abroad are powered by the mechanism, which can be operated locally or remotely. One motor outputs torque through the two-stage worm gear reducer, and drives the isolation switch or the grounding switch to realize the opening and closing operation. , During the operation process, use the limit switch to control the output angle of the oper...

AI Technical Summary

Problems solved by technology

At present, most of the problems in the field operation of high-voltage disconnectors are mechanism problems, which are mainly manifested in: the installation method of the mechanism is relatively simple, the output shaft of the disconnector can only be installed horizontally or vertically; the transmission is not flexible, divided, The closing process is prone to inadequacies; there are indeed few comprehensive mechanical and electrical locking measures inside the mechanism, and once the isolation and grounding switch body fails, effective protection cannot be obtained; there are few electrical solutions, which cannot meet the various requirements of the substation
