Rotation operation time difference signal trigger mechanism and isolating switch thereof

Abstract

The invention discloses a rotation operation time difference signal trigger mechanism and an isolating switch thereof. The rotation operation time difference signal trigger mechanism comprises a rotating shaft, a pulling element, a trigger element, and a trigger switch. The pulling element is driven by the rotating shaft. The trigger element has a first stroke capable of being driven by the pulling element in rotation angles of the rotating shaft. The trigger element has a second stroke capable of being triggered in rotation angles of the rotating shaft. The trigger switch is arranged on position of the first stroke or the second stroke of the trigger element. The mechanism can realize triggering of time difference signals in rotation operation under design principle of two strokes of the trigger element and generation methods thereof. When the mechanism is used in the isolating switch, the mechanism provides triggering of auxiliary contact pre-breaking signals in on-off operation, and realizes a trigger controlled by a remote control cabinet receives signals of the trigger switch to realize nonsynchronous pre-breaking and post-closing when the isolating switch in a switch box is switched off and switched on, so as to ensure safe operation.

Description

technical field

[0001] The invention relates to a mechanism capable of providing a time-difference signal for rotary operation, in particular a time-difference signal trigger mechanism capable of providing an auxiliary contact pre-breaking signal for a disconnector, and a disconnector adopting the rotary operation time-difference signal trigger mechanism. Background technique

[0002] Taking the current connection scheme of the isolating switch box and the main body of the remote control cabinet as an example, the isolating switch and its auxiliary switch are directly connected to the control circuit, and the isolating switch and its own auxiliary switch are located in the isolating switch box. The disadvantage of this connection method is that when the isolating switch inside the isolating switch box is disconnected and closed, the contactor controlled by the remote control cabinet is disconnected in advance and then closed synchronously. Personal safety poses a safety haza...
