Transformer TM, contactor 3KM1, neutral point.
7. power distributing and saving device according to claim 6, it is characterised in that：It to be adjusted to the 2nd grade for the 1st grade when economize on electricity routing
When, 2KM2 is connected first, then disconnect 1KM1, then connect 2KM1, then disconnect 2KM2, complete the 1st grade to the 2nd grade of switching
Journey, current-limiting resistance R play the role of afterflow and current limliting during gear switch, and the 3rd grade is adjusted to for the 2nd grade when economize on electricity routing
When, 3KM2 is connected first, then disconnect 2KM1, then connect 3KM1, then disconnected 3KM2, complete the 2nd grade to the 3rd grade of handoff procedure,
Current-limiting resistance R plays the role of afterflow and current limliting during gear switch, first when economize on electricity, which route the 3rd grade, to be adjusted to the 2nd grade
2KM2 is first connected, then disconnects 3KM1, then connects 2KM1, then disconnect 2KM2, completes the 3rd grade to the 1st grade of handoff procedure, current limliting
Resistance R plays the role of afterflow and current limliting during gear switch, when economize on electricity, which route the 2nd grade, to be adjusted to the 1st grade, connects first
Logical 1KM2, then 2KM1 is disconnected, 1KM1 is then connected, then disconnect 1KM2, completes the 2nd grade to the 1st grade of handoff procedure, current-limiting resistance
R plays the role of afterflow and current limliting during gear switch.
8. power distributing and saving device according to claim 5, it is characterised in that：The battery saving arrangement is divided into upper layer and lower layer；On
Layer is made of end of incoming cables circuit breaker Q F, leading-out terminal contactor 4KM and bypass contactor 5KM, and when electricity-saving state, electric current flows through inlet wire
Hold breaker, auto-transformer, leading-out terminal contactor 4KM；When bypass condition, electric current only passes through bypass contactor.
