Specific embodiment
Below in conjunction with Figure of description and specific embodiment, the invention will be further described.
As shown in figure 1, the Diesel Multiple Unit supplementary AC system of the present embodiment, including auxiliary power generation unit 1, deliver directly circuit
And all the way more than inverter circuit, auxiliary power generation unit 1 is by cooling blower 8 that inverter circuit is corresponding Diesel Multiple Unit
Powered with traction ventilator 9, auxiliary power generation unit 1 loads 10 confessions by delivering directly the direct screening that circuit is corresponding Diesel Multiple Unit
Electricity, also including train power supply generating set 2, first switch component 3 and second switch component 4, train power supply generating set 2 passes through
First switch component 3 is respectively air compressor 11, driver's air-conditioning 12, electricity accumulating unit 13 and the DC load of Diesel Multiple Unit
14 power supplies, auxiliary power generation unit 1 is respectively air compressor 11, driver's air-conditioning of Diesel Multiple Unit by second switch component 4
12nd, electricity accumulating unit 13 and DC load 14 are powered, and interlocking is formed between first switch component 3 and second switch component 4.The present invention
Assistant load air compressor 11, driver's air-conditioning 12 and battery and other DC loads 14 be the most necessary guarantor of EMUs
Card.Because air compressor 11 must assure that air feed, driver's air-conditioning 12 ensures personal security, and electricity accumulating unit 13 and other direct currents are negative
Carrying 14 ensures to control Electrical Safety.It is of the invention preferential（Normal condition）Train power supply generating set 2 is powered, by first switch group
Part 3（KB1 contactors）Directly export 380/50Hz to assistant load air compressor 11, driver's air-conditioning 12 and, electricity accumulating unit 13
And other DC loads 14；If the failure of train power supply generating set 2 or when not working, the auxiliary power generation unit 1 of main diesel engine group
