Abstract

Embodiments of the subject matter described herein provide a reduction mechanism (100) for a switching device and a switching device. The reduction mechanism (100) comprises: a shaft (1) adapted to rotate in response to the operation of an actuator to drive a moving element of the switching device; at least one reduction wheel (2) fixed to the shaft ( 1) with a deceleration profile (6); and a movable rocker (4) which engages the deceleration wheel (2). The reduction wheel (2) is adapted to cause the rocker (4) to move against a reduction profile (6) on the reduction wheel (2) in response to rotation of the shaft (1) in order to decelerate the rotation of the shaft (1). The deceleration mechanism can decelerate the operation of the moving element of the switching device without affecting the switching performance and service life of the switching device.

Description

Background technique [0001] Electrical automatic transfer switches are commonly used in power distribution systems to detect and monitor power quality and to transfer power between normal and backup power sources. Depending on the application scenario, dual power automatic transfer switches are generally divided into two types, namely, two-position switches (or simply two-position switches) and three-position switches (or simply three-position switches). For three-position switches, the contacts can stop in the open position where no connection to any power source is established. For a two-position switch, the contacts only transition between the two sources, without stopping. [0002] For a two-position switch, if the contacts of the switch transition between the two positions too quickly, the contacts may touch the other power source before the arc between the contacts and the previous power source is extinguished, causing an electrical arc between the two power sources. S...
