Description

Operating mechanism of automatic change-over switch and automatic change-over switch Technical Field The utility model relates to the technical field of piezoelectric devices, in particular to an operating mechanism of an automatic transfer switch and the automatic transfer switch. Background The Automatic Transfer Switch (ATSE) is mainly used for realizing automatic switching between a main power supply and a standby power supply so as to ensure power supply continuity, and has the core functions of rapidly switching off a main power supply loop and switching on the standby power supply when detecting main power supply faults (such as power failure, voltage abnormality and the like), and automatically or manually switching back to the main power supply after the main power supply is recovered. ATSE is widely used in hospitals, data centers, industrial facilities, and other places where high power supply reliability is required. Since the ATSE device needs to be switched on/off in two directions, the operating mechanism needs to be able to act in the forward and reverse directions, and the force values of the forward and reverse switching on/off are required to be consistent. For example, the operating mechanism needs to be capable of driving the handle to rotate reciprocally between a normal closing position and a standby closing position. In some switches, forward and reverse movement of an operating mechanism is realized by using forward and reverse rotation of a motor, but the action response of the motor is slower, so that an ATSE in the prior art usually adopts an electromagnet as a driving mechanism to realize rapid action, and in order to realize reversing action of the operating mechanism, two electromagnets are usually adopted to drive respectively. The technical scheme has the following defects that the manufacturing cost of the electromagnet is high, the cost of the switch equipment is increased by adopting the double electromagnets, and the installation space of the two electromagnets is reserved, and the two electromagnets are connected with the operating handle through the linkage mechanism, so that the occupied space is large, the assembly process is complex, and the miniaturization of the equipment is not facilitated. Therefore, there is a need for an operating mechanism of an automatic transfer switch and an automatic transfer switch to solve the above-mentioned problems in the prior art. Disclosure of utility model The utility model aims to provide an operating mechanism of an automatic transfer switch and the automatic transfer switch, wherein the operating mechanism can realize bidirectional movement through only one driving mechanism, the reliability is high, the cost is low, the occupied space is small, and the assembly process is simplified.

As an alternative to the operating mechanism of the automatic transfer switch provided by the present utility model, the operating mechanism further includes: The reversing assembly is connected with the rotating shaft assembly, when the rotating shaft assembly is positioned at the first closing position, the reversing assembly is stopped at one side of the transmission assembly along the first direction, and when the rotating shaft assembly is positioned at the second closing position, the reversing assembly is stopped at one side of the transmission assembly along the second direction; The first direction is the directi
