Delay transmission mechanism and mechanical switchover switch module using the mechanism

Abstract

The invention provides a delay transmission mechanism and a mechanically switching type change-over switch module using the same, for reducing distortion of the feedback of an electric signal when the change-over switch is in use. The mechanically switching type change-over switch module comprises two swing arms including a change-over switch clamping arm and a triggering lever, wherein the swing axes of the two swing arms are parallel to each other, a concave hook structure is arranged at the swing end of the change-over switch clamping arm to form a passive arm, a transmission crank arm structure linked with the concave hook structure is arranged at the swing end of the triggering lever to form an active arm, the inner wall face of the concave hook structure comprises an avoiding section and a transmission section, when the transmission crank arm structure passes through the avoiding section, the avoiding section moves away from the transmission crank arm structure, and when passing through the transmission section, the transmission crank arm structure drives the change-over switch clamping arm to move along with the same. After the triggering lever swings for a certain angle, the electric signal on the change-over switch can be switched, the phenomenon that in the existing change-over switch, the electric signal on the change-over switch is switched upon the action of the triggering lever is avoided, and the distortion of the feedback of the electric signal is reduced.

Description

technical field [0001] The invention relates to a delay transmission mechanism and a mechanical switch type transfer switch module using the mechanism. Background technique [0002] The transfer switch is used to switch the on-off of electrical components such as multiple circuit breakers, load switches or intelligent switches. An auxiliary electrical signal is provided on the transfer switch to display the switching completion of the electrical components. The existing transfer switch is usually The switch is performed by driving the cam structure to swing through the central shaft of the transfer switch, and the central shaft of the transfer switch is controlled by other circuit breakers or intelligent switches. When the traditional transfer switch is switched, the trigger device driven by the circuit breaker or the smart switch starts to move to drive the central shaft to swing, and the auxiliary electrical signal on the transfer switch is to switch the auxiliary electric...

Problems solved by technology

When the traditional transfer switch is switched, the trigger device driven by the circuit breaker or the smart switch starts to move to drive the central shaft to swing, and the auxiliary electrical signal on the transfer switch is to switch the auxiliary electrical signal, but at this time the transfer switch has not been switched by an electrical component to another electrical component, but the signal from the diverter switch has indicated that the transfer is complete, and the feedback is distorted

In this case, the auxiliary electrical signal cannot feed back the real working status of the electrical components

In addition, due to its own bounce, the circuit breaker or smart switch will transmit the bounce vibration to the trigger device, and the trigger device will transmit the vibration to the transfer switch, causing the transfer switch to bounce, causing mechanical damage and arc corrosion to the contacts of the transfer switch
