Embodiment 1

[0066] Such as figure 1 with figure 2 As shown, the three-position operating mechanism includes a frame and a transmission assembly installed on the frame. The frame includes a panel 6, a front mounting plate 7 and a rear mounting plate 8 arranged in sequence. The transmission assembly has an input end and an output end. The input end is used for operating torque input, the output end includes an output shaft 9, and the output shaft 9 is used to drive the moving contact 10 of the three-position switch to operate. An operation hole 61 corresponding to the position of the input end is provided on the panel 6 for inserting the operation handle 5 into the input end during manual operation.

[0067] The transmission assembly includes an input shaft, the input end is arranged on the input shaft, and the transmission connection between the input shaft and the output shaft is carried out through a transmission gear and a worm gear mechanism.

[0068] A drive shaft 4 is also installed...

Embodiment 2

[0102] The difference between this embodiment and Embodiment 1 is that the linkage mechanism in Embodiment 1 includes a transmission arm and a locking arm, but in this embodiment, only a locking arm is provided, and one end of the locking arm is connected to the slide plate , and the other end is used to cooperate with the unlocking pin.

Embodiment 3

[0104] The difference between this embodiment and Embodiment 1 is that the interlock mechanism in Embodiment 1 is provided with an interlock spring, which can automatically reset the slide to the blocking position after the operating handle is withdrawn. The lock mechanism is not equipped with an interlocking spring, and after the operating handle is withdrawn, the slide plate is manually moved to reset to the blocking position.

Abstract

The invention relates to a three-station operating mechanism and a switch cabinet. The switch cabinet comprises the three-station operating mechanism, the three-station operating mechanism comprises a rack, the rack is provided with a driving shaft, and the driving shaft is provided with a locking turntable; the self-locking piece of a self-locking mechanism is used for extending into a locking groove in the locking turntable to prevent the three-station operating mechanism from continuously acting; the interlocking piece of an interlocking mechanism is provided with a shielding position for shielding the input end and an avoiding position for avoiding the input end, and a triggering part arranged on the interlocking piece is used for triggering a generator loop to be switched on at the shielding position and triggering the generator loop to be switched off at the avoiding position; the locking piece of a linkage mechanism is used for driving the self-locking piece to be locked at the position away from the locking groove when the interlocking piece is located at a shielding position and unlocking the self-locking piece when the interlocking piece is located at an avoiding position; and the self-locking mechanism and the interlocking mechanism are in linkage design, the action of the interlocking mechanism is manually and electrically switched, the action of keeping the unlocking state / separating the unlocking state of the self-locking mechanism can be synchronously completed through the linkage mechanism, the functions are complete, and use is convenient.

Description

technical field [0001] The invention relates to a three-station operating mechanism and a switch cabinet. Background technique [0002] The three-position operating mechanism is an operating mechanism that drives the three-position switch to switch among the three positions of closing, isolation and grounding. It is driven by the internal transmission structure of the operating mechanism by inputting torque to the input end of the operating mechanism. The moving contact of the switch operates, and the three-station operating mechanism has a closing station, an isolating station and a grounding station corresponding to the three position states of the three-station switch. According to the needs of use, after the three-station operating mechanism reaches the corresponding station, it should be self-locked to keep the three-station operating mechanism at the corresponding station and avoid misoperation. At the same time, for the three-position operating mechanism that can be ...
