Abstract

A bypass type dual-power automatic change-over switch comprises a drawing frame, a first switch body and a second switch body, the first switch body and the second switch body are stacked up and down, a transmission device used for driving the corresponding switch body to move in the drawing frame is arranged between each switch body and the drawing frame, and a locking device is further arranged between each switch body and the drawing frame. The locking devices are associated with the opening and closing states of the corresponding switch bodies, lock the corresponding transmission devices to prevent the switch bodies from moving in the drawing frame when the corresponding switch bodies are in the closing state, and unlock the corresponding transmission devices when the corresponding switch bodies are in the opening state. And a connecting mechanism is arranged between the two locking devices, so that when one of the first switch body and the second switch body is in an opening state, the locking device corresponding to the switch body drives the other locking device through the connecting mechanism to lock the transmission device of the other switch body. Accuracy and reliability of on-off actions are ensured, and safety of user operation is improved.

Description

technical field [0001] The invention belongs to the technical field of low-voltage electrical appliances, and in particular relates to a bypass type dual power supply automatic transfer switch. Background technique [0002] In the technical field of electrical appliances, an automatic transfer switch (English abbreviation: ATSE) is used to provide an uninterrupted power supply for a load to ensure continuity of power supply. Although the known ATSE can realize the conversion between the two power sources to meet the power supply stability requirements, but when the ATSE itself fails, it has to perform short-term power-off maintenance, thereby having a corresponding impact on the continuity of power supply. In order to ensure the continuity of the power supply, that is, to provide continuous power supply when the ATSE itself fails, an alternate conversion system consisting of two sets of transfer switch appliances is used, so that when one of the transfer switch appliances fa...
