Embodiment Construction

[0031] The present invention as Figure 1-4 As shown, it includes a switch body 3, a knob 2, a square handle 33 and a panel connecting the switch body 3 and the knob 2, the outer surface of the lower part of the knob 2 is cylindrical, and the upper part is provided with a knob 22. There is also a locator assembly between the switch body 3; it should be noted that: the axis of the knob 2 is provided with a square hole 23 adapted to the square handle 33, so as to realize the operation of the switch.

[0032] The locator assembly includes a convex pin 31, a locator 1 with a middle hole 11 and a compression spring 5;

[0033] The back side of the locator 1 facing one end of the panel is provided with a plurality of holes 12 on the back side, and the plurality of holes 12 are evenly distributed on the same circumference of the back side; the front edge of the locator 1 is symmetrical A pair of fan-shaped protrusions 13 are provided on the ground, and a pair of fan-shaped gaps 14 (...

Abstract

A control switch. It relates to the improvement of the operation structure of the control switch. Avoid continuous cutting of two gears, thereby preventing misoperation. It includes a switch body, a knob, a square handle and a panel connecting the switch body and the knob, and a locator assembly is arranged between the knob and the switch body; the locator assembly includes a convex pin, a locator with a middle hole, and a compression spring; the locator The back facing one end of the panel is the back, and the back is provided with a number of holes, which are evenly distributed on the same circumference of the back; a pair of fan-shaped protrusions are symmetrically arranged on the front edge of the locator, and a pair of fan-shaped protrusions are arranged on the back. There is a pair of fan-shaped gaps between the protrusions that can limit the rotation angle of the handle symmetrically; the middle hole of the locator is pivotally connected with the lower part of the cylindrical knob; the compression spring is arranged between the front of the locator and the knob; the protrusion The pin is located on the panel and protrudes toward the direction of the locator. The protruding pin deviates from the axis of the square shank, and the distance from the axis of the square shank is the size of the radius of the circle where the hole is located. It can avoid accidental touch without changing the original circuit.

Description

technical field [0001] The invention relates to a control switch used in power transformation, in particular to the improvement of the operation structure of the control switch. Background technique [0002] In substations with traditional control methods, the control switch is the only way to artificially control the switch. In order to prevent the switch from being opened and closed by mistake, the control switch adopts a special structure. Open position -> open position, which can reliably prevent mis-opening of the switch, coupled with flopping and other means, prevents vicious misoperation accidents of mis-opening and closing the switch. [0003] In newly invested substations or substations after comprehensive self-renovation, the main means of controlling the switches is to monitor the background operation, and at the same time, the control switches are installed on the measurement and control devices as backup operations. Because this control switch is a backup op...
