Abstract

The present invention relates to an electric operation module of a direct-acting three-position disconnector and an application method thereof. The electric operation module of the direct-acting three-position disconnector comprises a mounting rack; one side of the mounting rack is provided with a controller and a driving motor located on an upper side of the controller; a motor output shaft of the driving motor is provided with an axial through-hole; a pair of one-way bearings in opposite mounting directions are meshed in the axial through-hole; a transmission shaft with an output end extending out of the other side of the mounting rack runs through the one-way bearings; an output shaft used for connecting a gear transmission assembly is arranged on the output end of the transmission shaft; a switching handle for driving transmission shaft to move transversely is arranged on the output shaft; and the mounting rack is further provided with a rotary encoder that is connected to another synchronous output shaft though a coupler. The operating mechanism is not only compact in structure, but also helpful in solving the isolation position "drift" problem.

Description

technical field [0001] The invention relates to an electric operation module of a direct-acting three-position isolating switch and a use method thereof. Background technique [0002] In recent years, a wide variety of solid insulated switchgears have emerged in medium voltage switchgear products. Its typical circuit consists of three-position isolating switch and load switch (or circuit breaker). Existing three-position isolating switches generally have two structures: direct-acting type and switch-knife switch-type structure. The direct-acting structure is more and more adopted than the switch-type structure because it takes up less space. The common disadvantage of both structures is that the isolation position cannot achieve accurate mechanical limit, and it is easy to cause the isolation position to "drift", so that the distance from the isolation to the closing or grounding position is not a fixed value. Contents of the invention [0003] The purpose of the present...
