This, improve hot property, it by distribution region important area and insignificant region be divided into two area of isolation, limit failure
Coverage.
Description of the drawings
Fig. 1 is the functional block diagram of low-voltage direct distribution system in the prior art.
Fig. 2 is the functional block diagram of low-voltage direct distribution system described in the utility model.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.Shown in Fig. 2, described in the utility model one
The low-voltage direct distribution system in kind general-purpose aircraft distribution region, including：Busbar, contactor, rack, voltage device, electric current are surveyed
Device is measured, the busbar includes important busbar 1, general busbar 2 and emergent busbar 3, and generator passes through busbar
Directly by the electrical equipment of electrical energy transportation to general-purpose aircraft, it is connected to by one between the important busbar 1 and general busbar 2
The electrodynamic mechanical type contactor 4 of a internal logic and the driving of a directional current sensor, the important busbar 1 converge with emergent
Connect respectively between stream item 3, general busbar 2 and emergent busbar 3 there are one leakage circuit breakers 5, carry out reverse-current protection,
The power attenuation occurred when using conventional diode is reduced simultaneously.
As shown in the figure, distribution region described in the utility model be divided into important area 6 and 7 two, insignificant region mutually every
From region, it is connected to respective power generation respectively on the important busbar 1, general busbar 2 in two mutually isolated regions
Machine input 11,21 and dynamo current export 12,22 and wiring, Bus Voltage output line 13,23, confluence 1 work song item it is defeated
Go out 14,24 and 2 work song items of confluence output 15,25, be connected on the emergent busbar 3 emergent confluence voltage output 31,
1 work song item of emergent confluence output 32 and 2 work song items of emergent confluence output 33；All shielded outputs in the distribution region
It is all made of substantially solid power controller module, and the solid-state power controller will be integrated on integrated circuit board；It is described
Voltage device and current measuring device be arranged as circuit monitoring and internal electron logic and defencive function.
The utility model is connect using the electrodynamic mechanical type that an internal logic circuit and a directional current sensor drive
Tentaculum 4 realizes the connection between important busbar 1 and general busbar 2；The internal logic circuit meets general remittance at the same time
Stream item 2 have input, on important busbar 1 without input, without connecting contactor under conditions of reverse current.When contactor is connected,
Mean that general busbar 2 will power to important busbar 1.If important generator operation, and voltage is higher than general confluence
, then there is reverse current in the voltage on item 2, at this point, directional current sensor will monitor this reverse current, it is more than to fix in electric current
When value, internal logic circuit will be switched off contactor, realize the purpose of protection circuit；It to be such as closed contactor again, need to expire simultaneously
The above-mentioned general busbar of foot 2 has input, on important busbar 1 without input, the condition without reverse current.
In addition, the utility model is avoided that mistake when also there is defencive function can make important busbar 1 that short circuit surprisingly occur
Effect is transmitted.After being closed contactor, directional current sensor flows to the electricity of important busbar 1 by monitoring from general busbar 2
Stream, if electric current is more than fixed threshold value, internal logic circuit will be switched off contactor, to which deenergization power supply also has one
As connection between busbar and important busbar.In this case, circuit will lock up the trip signal, it is necessary to have operation
The reset signal that person sends out either disconnecting device power supply could release.
General generator input and the input of important generator are connected directly between on internal essential bus, and are not connect with circuit
Tentaculum, by needing installation fuse to protect circuit in short circuit.
The utility model is realized using leakage circuit breakers 5 connects important busbar 1 and emergent busbar 3, general busbar 2
With the connection between emergent busbar 3.Leakage circuit breakers 5 is to be based on using dual analog solid-state current rectifier assembly（SSPC）Solution
Certainly scheme, for avoiding reverse current.For 5 switch element of leakage circuit breakers compared with the pressure drop on diode, the loss of voltage is lower,
Using this technology, failure when can be to avoid busbar short circuit is transmitted, and reduces power attenuation.Each dual analog solid-state electric current
Fairing monitors output current, if electric current is in the level that the time content of restriction is more than definition, dual analog solid-state electricity
Stream fairing will be switched off.After large current load tripping, leakage circuit breakers function must have the reset that operator sends out
Signal either disconnecting device power supply could release.
All breakers of the utility model, solid-state power controller and the logic function defined before this are all located at and are fixed on
On two integrated circuit boards in rack, and carry out isolation processing.Two pieces of circuit boards are all the electricity for being exclusively used in a certain specific region
Gas network area, one piece is used for important area, and one piece is used for insignificant region.Limit fault coverage.Using voltage device and
Current measuring device realizes circuit monitoring and internal electron logic and defencive function.
