Title:
INTERLOCK DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/123285
Kind Code:
A1
Abstract:
An interlock device (100) for a bypass device comprises: a RIRO mechanism (101) configured to drive the ATSE from a non-operating position to an operating position and drive the ATSE from the operating position to the non-operating position; a first interlock mechanism (102) configured to prevent the RIRO mechanism (101) from driving the ATSE from the non-operating position to the operating position when the first switch and the fourth switch are both switched on; and a second interlock mechanism (103) configured to prevent the RIRO mechanism (101) from driving the ATSE from the non-operating position to the operating position when the second switch and the third switch are both switched on. The ATSE and MTSE cannot connect two power supplies to the load at the same time through using the first interlock mechanism (102) and the second interlock mechanism (103), and no controller is needed to achieve the interlocking between the ATSE and MTSE.
