Description
Technical Field
The invention belongs to the technical field of isolating switches, and particularly relates to an opening and closing stroke adjusting device, a switch operating mechanism and a switch.
Background
The switching-on and switching-off stroke adjusting device is an important component in a switching mechanism box and controls the switch to automatically complete the switching-on and switching-off operation.
For example, the control device for the earthing switch disclosed in the patent application in chinese invention with application publication No. CN112289619A, wherein a combination structure of a micro switch and a cam is respectively adopted for the opening and closing indication. However, when the switch is used in a direct current field, no matter switching off or switching on, the cam acts after reaching 80% of the whole switching on and switching off process of the switch body, if the cam is theoretically set to act at 100% of the switching on and switching off process of the body, because the switching on and switching off time is several seconds or even tens of seconds, and the error is +/-2 seconds, if the switching on and switching off of the switch body is advanced by 1 second, the cam cannot act, and thus a switching on and switching off in-place signal cannot be sent.
For another example, the chinese utility model patent with the granted bulletin number of CN202230933U discloses a totally closed isolator switch singleness disconnection indicating mechanism, including the isolator body and moving contact and the static contact of setting on the isolator body, set up travel switch on the isolator body, the moving contact back on travel contact and the isolator body is connected, when the isolator moves, the moving contact on the isolator body leaves the static contact, when the separating brake arrives a certain position, the moving contact back drives travel switch's travel contact, after the separating brake targets in place, the power and the pilot lamp intercommunication of establishing ties on travel switch's the normally closed contact, the separating brake targets in place. However, as the travel switches are required to be arranged in a plurality of numbers, the moving contacts of the travel switches can not perform synchronous action easily, namely, the problem of poor action consistency of the moving contacts is easily caused, so that the moving contacts can not be in synchronous contact with the fixed contacts, and further, the transmission of the opening and closing in-place signals is more inaccurate.
In summary, the opening and closing stroke adjusting device in the prior art cannot provide an opening and closing in-place signal, or the provided opening and closing signal is not accurate enough, which seriously affects the next step of sequence control.
