The technical solution used in the present invention is: a kind of DC distribution panel of helicopter, base plate are provided with generator power supply circuit, ground power supply circuit and storage battery source circuit, and its technical characterstic is that described base plate is the insulating base of composite material; The generator power supply circuit comprises fuse, instrument transformer and the first D.C. contactor, and generator power supply passes the B end that instrument transformer connects the first D.C. contactor, and the A end of the first D.C. contactor connects fuse through the first busbar; Described ground power supply circuit comprises fuse and the second D.C. contactor, and ground power supply is held through the B that the second busbar connects the second D.C. contactor, and the A end of the second D.C. contactor connects fuse through the first busbar; Described storage battery source circuit comprises fuse, reversed current protector and the 3rd D.C. contactor, reversed current protector is held through the A that the 3rd busbar connects the 3rd D.C. contactor 11, and the B end of the 3rd D.C. contactor connects the B end of the first D.C. contactor through the 4th busbar; Described first, second and third D.C. contactor all connects the switching that breaker assembly on the insulating base and relay assembly are realized generator power supply circuit, ground power supply circuit and storage battery source circuit.
Further, the B of described the 3rd D.C. contactor 11 end connects the first busbar.
Again further, described first, second, third and fourth busbar all is fixed on the insulating base.
The beneficial effect that the present invention reaches is:
1, base plate adopts the insulating base of composite material, fundamentally solved the potential safety hazard of transmitting electric leakage, the base plate weight ratio aluminium of this composite material is light, be higher than designing requirement, by cold test, high-temperature test (+60 ° of C), low-temperature test (40 ° of C), temperature shock test, vibration test, shock test, acceleration test, salt mist test, mould test, the humid heat test of national Specification, its intensity of evidence, hardness, toughness, ageing properties all can satisfy the aircraft utilization requirement;
2, adopt many fuse and a plurality of contactors on the busbars connection distribution panelboard, each busbar bifurcated connects remaining component on fuse, a plurality of contactor and the distribution panelboard, solved that the operation of a plurality of contactors of a plurality of connector separate connection of traditional employing, fuse is loaded down with trivial details, the easy problem such as loss of connector, be conducive to rapid-maintenance, replacing on the helicopter of small space.
The present invention is on the insulating base of composite material, to be fixed on the finished products such as D.C. contactor on the base plate, fuse by many busbars organically combines, safety realizes the power supply control of helicopter DC power system and the conversion of various DC power supply, it is simple in structure, compact, loading and unloading, easy to maintenance, without electric leakage hidden danger, usage safety performance is high.
