Through the circuit structure, the commercial power 1 and the commercial power 2 and the oil engine 1 and the oil engine 2 can realize intelligent switching power supply of a power supply circuit. Under the intelligent mode, power switching box and intelligent distribution box work automatically according to the preset program. Under normal conditions, the power supply priority is that the commercial power 1 is greater than the oil engine 1, the commercial power 2 is greater than the oil engine 2, and the power supply interchange of the commercial power 1 and the commercial power 2 with the oil engine 1 and the oil engine 2 can be realized by opening the alternating current intelligent power distribution modules A1-A4 on the alternating current lines A1, b1, a2 and b2.
For example, when the commercial power 1 and the commercial power 2 are normally supplied with power as well as the oil engine 1 and the oil engine 2, the commercial power 1 and the commercial power 2 are preferentially adopted for supplying power, the switching ac intelligent power distribution modules A1 and A3 start output voltages to electrify the ac contactors K1 and K3, the ac lines A1 and a2 are conducted, and the output end of the ac intelligent power distribution module A4 is connected with the normally closed contact of the ac contactor K3, so that the ac contactor K4 coil cannot be electrified and the oil engine 2 does not work.

And a second power supply bus is formed after the alternative selection of the commercial power 2 and the oil engine 2, and the bus is controlled by the breaker QF 1.

When only the second load line is used, but the equipment on the second load line is not used, and the equipment on the first load line needs to be used, the second output end of the alternating current intelligent power distribution module A5 is matched with the alternating current contactor K5 to control the conduction of the second branch line II, and the second branch line II is connected to the first load line to supply power for the intelligent power distribution box. The first load circuit is normally intended for use by the appliance and the second load circuit is normally intended for use by the air conditioner.
Under the emergency mode, the commercial power emergency and the oil engine emergency can be adopted. In a preferred embodiment, the ac line b1 is connected to the first load line after being connected in series with one set of normally open contacts of the second switch through the first fourth branch line, and the ac line b2 is connected to the second load line after being connected in series with the other set of normally open contacts of the second switch through the second fourth branch line.
Through the circuit structure, the oil engines 1 and 2 can realize emergency switching power supply for load circuits. For example, when the oil engine is in an emergency, the second switches on the first and second branch lines are manually and directly opened, the alternating current line b1 supplies power for the equipment line in an emergency through the first branch line, and the alternating current line b2 supplies power for the air conditioning line in an emergency through the second branch line. At the moment, the input is directly connected with the output to supply power, and the protection and display functions are not required.
In a preferred embodiment, the ac line a1 is connected in series with one set of normally open contacts of the first switch through a first third branch line and then connected to the first load line, and the ac line a2 is connected in series with the other set of normally open contacts of the first switch through a second third branch line and then connected to the second load line;
through the circuit structure, the commercial power 1 and the commercial power 2 can realize emergency switching power supply of the load circuit. For example, when the commercial power is in an emergency, the first switches on the first and second branch lines are directly manually opened, the alternating current line a1 supplies power for the equipment line in an emergency through the first branch line, and the alternating current line a2 supplies power for the air conditioning line in an emergency through the second branch line. At the moment, the input is directly connected with the output to supply power, and the protection and display functions are not required.
In a preferred embodiment, the first branch line is connected to the second load line after being connected to one set of contacts of the third switch via the first branch line, and the second branch line is connected to the first load line after being connected to the other set of contacts of the third switch via the second branch line.
Through the circuit structure, the oil engines 1 and 2 can be interchanged, and emergency switching power supply of a load circuit is realized. For example, when the oil engine 1 has a fault, the fourth branch line cannot supply power to the equipment line through the second switch, at the moment, the third switch is manually opened, and the fourth branch line passes through the second fifth branch line to supply power to the equipment line, so that emergency power supply is realized.
Therefore, through the description of the embodiment, the intelligent power distribution control over the mains supply input and the oil engine input is realized through the intelligent power distribution box, the emergency control over the mains supply input and the oil engine input is realized, the emergency switching function of the multi-path alternating current input when the intelligent mode fails is guaranteed, and the normal execution of military vehicle combat tasks in the plateau frontier defense area is guaranteed.
