Description
Technical Field
The utility model belongs to the technical field of isolating switches, and particularly relates to a switching-on and switching-off stroke adjusting device, a switch operating mechanism and a switch.
Background
The opening and closing stroke adjusting device is an important part in the switch mechanism box and controls the switch to automatically complete opening and closing operations.
For example, a control device for a grounding switch disclosed in chinese patent application publication No. CN112289619a, wherein a combination structure of a micro switch and a cam is adopted for the opening/closing indication, respectively. However, when the switch is used in a direct-current field, no matter the switch is opened or closed, the cam acts after 80% of the whole switching-on and switching-off process of the switch body is achieved, if the cam is theoretically set to act when 100% of the switching-on and switching-off process of the switch body is achieved, the switching-on and switching-off time of the switch is a few seconds or even tens of seconds, the error is +/-2 seconds, and if the switching-on and switching-off of the switch body are advanced by 1 second, the cam cannot act, so that a switching-on and switching-off in-place signal cannot be sent.
For example, the Chinese patent publication No. CN202230933U discloses a totally-enclosed disconnecting switch single-item disconnection indicating mechanism, which comprises a disconnecting switch body, a moving contact and a fixed contact, wherein the moving contact and the fixed contact are arranged on the disconnecting switch body, a travel switch is arranged on the disconnecting switch body, the travel contact is connected with the back of the moving contact on the disconnecting switch body, when the disconnecting switch acts, the moving contact on the disconnecting switch body leaves the fixed contact, when the disconnecting switch is in a certain position, the back of the moving contact drives the travel contact of the travel switch, after the disconnecting switch is in place, a power supply and an indicating lamp which are connected in series on a normally-closed contact of the travel switch are communicated, and the disconnecting switch is in place. However, because the travel switch needs to be provided with a plurality of travel switches, a plurality of moving contacts of the travel switches cannot synchronously act, namely the problem of poor action consistency of the moving contacts is easily caused, the moving contacts cannot synchronously contact with a plurality of fixed contacts, and further, the transmission of in-place opening and closing signals is more inaccurate.
In summary, the switching-on/off stroke adjusting device in the prior art cannot provide a switching-on/off in-place signal, or the provided switching-on/off signal is not accurate enough, so that the next step of sequential control is seriously affected.
