Road.
In the dual-power transfer switch of bypass type, namely by-pass switch and dual-power transfer switch it
Between need also exist for such mechanical interlocking, i.e. connect one of them power supply as TSE, during power supply as usual,
This mechanical interlocking only allows by-pass switch to connect conventional power supply, and is not turned on another power supply, as standby
Power supply.Equally, this mechanical interlocking is when conventional power supply connected by by-pass switch, and TSE operation is then not turned on
Stand-by power supply, to ensure to cause between two power supplys because of the operation of mistake during the use of equipment
Short circuit.Owing to TSE needs because the reasons such as maintenance need to shake out taking out in frame or use of bypass type TSE
Shaking into taking out frame, such mechanical interlocking is to float with coupling of TSE, thus causes mechanical interlocking structure
Complexity.Some manufacturer provides and lacks the operation interlocking of by-pass switch from by-pass switch pair from TSE
The operation interlocking of TSE, uses TSE manual operation can not prevent the peace of possible short circuit between two power supplys
Full problem.Some manufacturer then uses the interlock of electromagnetic type, but cannot avoid because artificial operation is wrong
Cause the short circuit between two power supplys by mistake.

If being to be powered by stand-by power supply before dual-power transfer switch, it is invalid that second mechanical interlocking causes by-pass switch to commonly use on and off switch closing operation, now the second driven part of main shaft goes to closing position at the driving backspin of dual-power transfer switch Backup Power Switch main shaft, and drive the second separating brake dropout actuator to rotate to trip positions by second connecting rod, the conventional power supply closing operation being now connected with by-pass switch is invalid, and the stand-by power supply being connected with by-pass switch can close a floodgate because by-pass switch stand-by power supply separating brake release lever is not controlled by any mechanical interlocking；
If being to be powered by conventional power supply before dual-power transfer switch, 4th mechanical interlocking causes by-pass switch Backup Power Switch closing operation invalid, the driving backspin that now the driven part of four main commonly uses on and off switch main shaft at dual-power transfer switch goes to closing position, and drive the 4th separating brake dropout actuator to rotate to trip positions by fourth link, the stand-by power supply closing operation being now connected with by-pass switch is invalid, and the conventional power supply being connected with by-pass switch is commonly used power supply separating brake release lever because of by-pass switch and do not controlled by any mechanical interlocking and can close a floodgate.
Mechanical interlocking the most according to claim 7, it is characterised in that:
When described dual-power transfer switch is shaken and is taken out frame into installation,
If being to be powered by stand-by power supply before by-pass switch, it is invalid that 3rd mechanical interlocking causes dual-power transfer switch to commonly use on and off switch closing operation, now the 3rd driven part of main shaft goes to closing position at the driving backspin of by-pass switch Backup Power Switch main shaft, and drive the 3rd separating brake dropout actuator to rotate to trip positions by third connecting rod, the conventional power supply closing operation being now connected with dual-power transfer switch is invalid, and the stand-by power supply being connected with dual-power transfer switch can close a floodgate because dual-power transfer switch stand-by power supply separating brake release lever is not controlled by any mechanical interlocking；
If being to be powered by conventional power supply before by-pass switch, first mechanical interlocking causes dual-power transfer switch Backup Power Switch closing operation invalid, the driving backspin that now the first driven part of main shaft commonly uses on and off switch main shaft at by-pass switch goes to closing position, and drive the first separating brake dropout actuator to rotate to trip positions by first connecting rod, the stand-by power supply closing operation being now connected with dual-power transfer switch is invalid, and the conventional power supply being connected with dual-power transfer switch is commonly used power supply separating brake release lever because of dual-power transfer switch and is not controlled by any mechanical interlocking and can close a floodgate.
