Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Referring to Fig. 1, the present invention provides a kind of technical scheme：A kind of charger door opening electrical outage safeguard protection, including first
Loop 1 and second servo loop 5, the both upper ends thereof in first loop 1 are in series with power switch 13 respectively, and under power switch 13
End is in series with second servo loop 5, and the left end of the second servo loop 5 is in parallel to be provided with the second connecting line 3, and between the second connecting line 3
Travel switch 7 is in series with second servo loop 5, be sequentially connected in series from left to right on second connecting line 3 change-over switch 11 and when
Between relay 6, the middle part of the second servo loop 5 is in series with stop button 8, the right-hand member of the second servo loop 5 be in series with startup by
Button 10 and main contactor 9, and start button 10 is located at the left side of main contactor 9, the both ends of the start button 10 are respectively with
The both ends connection of three connecting lines 4, and main contactor 9 is in series with the 3rd connecting line 4, the bottom left end string in first loop 1
It is associated with change-over switch 11, and the bottom right-hand member in the first loop 1 is parallel with the first connecting line 2, between first connecting line 2
Primary Ioops 1 are provided with the time relay 6, and are sequentially connected in series from left to right on the first connecting line 1 provided with the time relay 6 and maintenance
Indicator lamp 12, the closure of main contactor 9, cut-off and realized respectively by operating start button 10 and stop button 8, in second servo loop
3 back door travel switches 7 of upper increase, the quantity of the travel switch 7 is three, and travel switch 7 is connected on second servo loop 5
