Abstract

The present invention relates to automatic transfer switching equipment, comprising an actuating mechanism (10, 10'), wherein said actuating mechanism (10, 10') can perform rectilinear motion under an external force, when a miniature circuit breaker (80) is used by the automatic transfer switching equipment, at least two pairs of shifting blocks (11) are perpendicularly and symmetrically arranged on said actuating mechanism (10), and when a molded case circuit breaker (80') is used by the automatic transfer switching equipment, two shifting blocks (11') are perpendicularly and symmetrically arranged on said actuating mechanism (10'), and in these two cases, each of said shifting blocks (11, 11') is provided with an arc surface, and during the rectilinear motion of said actuating mechanism (10, 10'), said shifting block (11, 11') on one side is in contact with a handle (82, 82') of the circuit breaker (80, 80') through at least part of said arc surface, and drives said handle (82, 82') to switch off or switch on said circuit breaker (80, 80'). Since shifting blocks are perpendicularly arranged on the actuating mechanism, the introduction of other extra auxiliary parts can be avoided, thereby reducing the cost. Moreover, a shifting block which is at least provided with part of the arc surface performs rectilinear motion with the actuating mechanism, which can also greatly reduce the friction force between the shifting block and the handle, and the risk of failure in ATSE transfer is reduced.
