Interlock device

An interlock device for a bypass device, the bypass device being configured to switch a load between a main power supply and an auxiliary power supply and comprising an Automatic Transfer Switching Equipment (ATSE) having a first switch coupled to the main power supply and a second switch coupled to the auxiliary power supply and a Manual Transfer Switching Equipment (MTSE) having a third switch coupled to the main power supply and a fourth switch coupled to the auxiliary power supply, the interlock device comprising:

• a mounting plate having a first side and a second side opposite to the first side;
• and
• a third interlock assembly configured to prevent the fourth switch from being closed when the first switch is closed, wherein the third interlock assembly comprises:
• a first rotating shaft extending through the mounting plate and comprising a first end located at the first side of the mounting plate and a second end located at the second side of the mounting plate;
• a first rotating sheet fixed to the second end of the first rotating shaft and configured to be driven by a first indicator to rotate from a first position to a second position when the first switch is switched from an open state to a close state, wherein the first indicator is coupled to a first main shaft of the first switch;
• and
• a third driving assembly coupled to the first end of the first rotating shaft and configured to push a first operating bar for pressing a close button of the fourth switch away from the close button when the first rotating sheet rotates from the first position to the second position.

• a mounting plate having a first side and a second side opposite to the first side;
• a first support member arranged at the first side of the mounting plate and comprising a first guiding hole extending in a first direction and a second guiding hole extending in a second direction;
• a first interlock assembly configured to prevent the fourth switch from being closed when the first switch is closed and comprising:
• a first driving assembly coupled to a first main shaft of the first switch;
• and a first blocker coupled to the first driving assembly and being movable along the first guiding hole in the first direction under driving of the first driving assembly when the first switch is switched between a close state and an open state, wherein the first blocker is configured to block a first indicator coupled to a fourth main shaft of the fourth switch when the first switch is in the close state and not block the first indicator when the first switch is in the open state;
• and
• a second interlock assembly configured to prevent the third switch from being closed when the second switch is closed and comprising:
• a second driving assembly coupled to a second main shaft of the second switch;
• and a second blocker coupled to the second driving assembly and being movable along the second guiding hole in the second direction under driving of the second driving assembly when the second switch is switched between a close state and an open state, wherein the second blocker is configured to block a second indicator coupled to a third main shaft of the third switch when the second switch is in the close state and not block the second indicator when the second switch is in the open state.
