Integrated three-position isolating switch and its production and processing method

Abstract

The present invention provides an integrated three-position isolating switch and a production and processing method thereof, which belongs to the field of isolating switches. The integrated three-position isolating switch is composed of a support rod, a bracket mechanism, a connector D, a connector C, a connector B, a connector A, a fixing mechanism and a mold mechanism. In this solution, the connector D, the connector C and the connector B have the same center of a circle and are an integrated structure, so that the static contact is easy to install, the concentricity adjustment is simpler, and the error is small. The rotation of the hexagonal block can drive the threaded rod B to rotate, and the rotation of the threaded rod B can drive the T-type threaded sleeve to slide in the T-type slide groove. The movement of the T-type threaded sleeve can drive the movement of the arc clamping block. The movement of the two arc clamping blocks can clamp the parts that need to be installed on the connector B and the connector D, thereby improving the stability of the installation. This can solve the problem that errors may occur during the installation of the three-position isolating switch in the prior art, resulting in the need for debugging after installation testing, which increases the difficulty of installation.

The integrated three-position disconnect switch according to claim 4, characterized in that: Each group of the limiting components includes a threaded rod A (5), a limiting ring (27), an operating block (28), a slide B (29) and an inner hexagonal groove (33), two limiting rings (27) are provided, each limiting ring (27) is fixedly connected to the circumferential surface of each slide rod (26), the slide B (29) is slidably sleeved on the two slide rods (26), and the slide B (29) is located between the limiting ring (27) and the slide A (25), two inner hexagonal grooves (33) are provided, each inner hexagonal groove (33) is opened at one end of each slide rod (26), the threaded rod A (5) is threadedly connected to one end of the slide B (29), and the threaded rod A (5) rotates through the slide B (29) and supports the slide A (25), and the operating block (28) is fixedly connected to one end of the threaded rod A (5); A C-GIS connecting plate (22) is fixedly connected to the surface of the connecting head D (21).

6. The production and processing method of the integrated three-position isolating switch is characterized in that: The integrated three-position disconnect switch according to claim 5 is applied, comprising the following steps: S1. Thread the internal threaded sleeve (9) onto the external threaded sleeve (8), rotate the swivel (14), and thereby adjust the positions of the two arc-shaped clamping blocks (10). After the positions of the two arc-shaped clamping blocks (10) are adjusted, rotate the locking screw A (4). The locking screw A (4) moves while the internal threaded tube B (30) rotates, thereby supporting the internal threaded sleeve (9), and fixing the positions of the two arc-shaped clamping blocks (10). S2, rotating the hexagonal block (12), the rotation of the hexagonal block (12) drives the threaded rod B (24) to rotate, the rotation of the threaded rod B (24) drives the T-shaped threaded sleeve (11) to slide in the T-shaped slide (6), and the movement of the T-shaped threaded sleeve (11) drives the arc clamping block (10) to move; S3. The sliding rod (26) is rotated through the inner hexagonal groove (33). The rotation of the sliding rod (26) drives the screw rod (32) to rotate. After the screw rod (32) rotates, it is threadedly connected to the inner threaded tube A (18), thereby installing the solid sealing mold (19). The operating block (28) is rotated. The operating block (28) rotates and drives the threaded rod A (5) to rotate. The threaded rod A (5) moves while rotating on the slide plate B (29). The threaded rod A (5) moves and pushes the slide plate A (25) to slide on the two sliding rods (26). The slide plate A (25) moves and drives the mounting frame (20) to move. The mounting frame (20) moves and drives the solid sealing mold (19) to move. The two solid sealing molds (19) move and are docked.
