Description
Technical field
The present invention relates to satellite centrally connected power supply power expanding and need for reliable backup method and circuits.
Background technology
Power supply and distribution subsystem ground checkout equipment is essential component in satellite development process.It is concentrated on ground
In power supply mode, use the single supply way of output as power satellite more.But single supply power supply exists certain again in integration test
The drawbacks of：
(1) separate unit output power of power supply is limited, it is difficult to meet high-power platform requirement at present
Telecommunication satellite platform is progressively developing, and power demand is increasing, and the requirement to ground checkout equipment is higher and higher.
For at present frequently with Aglient D.C. regulated power supply products, on the basis of satellite busbar voltage is met, output current by
Limit.If powered using separate unit power supply, whole star large power test demand cannot be met.
(2) during whole star electrical measurement, single supply output abnormality may cause whole star power down failure, cause satellite unit by
Damage.
Some stages of telecommunication satellite integration test are mainly powered using centralized power supply system for whole star.Use a power supply
As centrally connected power supply means, under power failure condition, whole star power down can be caused, on-board equipment is made to be in indeterminate state, and easily
Equipment is damaged, problems occurred in the past.
(3) troubleshooting is there are risk, and influences testing efficiency
, it is necessary to which tester replaces backup mode manually carries out troubleshooting after single supply failure, and carrying out equipment more
When changing, many places can not carry out joint debugging verification, if at this time to electric power system in advance in connection status between equipment and satellite interface
When there is cabling error, positive and negative reversal connection, virtual connection, irreversible damage can be caused to satellite.Meanwhile satellite test
It interrupts, ground installation replacement can influence test process.
(4) Flied emission day unattended demand is emitted
Usually on the transmitting same day, power supply and distribution post tester between the test of launch site, tests with centrally connected power supply equipment
Personnel carry out takeoff condition setting, monitor product and ground installation state on star, until transmitting first few minutes tester can
It withdraws.But for some launch environments, do not possess personnel and accompany appointed condition, it is desirable that tester is whole between the test of launch site
It withdraws, and centrally connected power supply equipment is required to ensure that launch mission is satisfactorily completed in the case of unattended.If still using single
Power supply power supply mode once there is abnormity of power supply, then cannot in time handle it to abnormal power supply, can influence big system transmitting day
Flow.In order to enhance power supply output reliability, using power supply hot reserve scheme, it is different can to solve single supply for double power supply parallel output
Chang Wenti.

Specific embodiment
Satellite centrally connected power supply, if using a D.C. regulated power supply as power supply output equipment, the connection of device external interface
Relation samples access control relay all the way as shown in Figure 1, containing the control relay of power flow all the way inside main battle array distributor
Device, repeat circuit be magnetic latching relay, double-contact Parallel Control access break-make.D.C. regulated power supply power output anode connects
Supply access relay anode in main battle array distributor is connect, negative terminal connects a busbar negative terminal, and relay rear end passes through reverse-filling two
Pole pipe is connected to a busbar anode, so as to be whole star load supplying.Power supply output is arranged to constant pressure output mode, output voltage
It is set according to a character, output current is according to power supply maximum output capabilities setting.
Fig. 1 power supply modes, once D.C. regulated power supply failure, processing mode is more complicated, as shown in Figure 3.Direct current is steady
There is overvoltage protection in voltage source, exports as 0, and telemetering is abnormal when failure problems, it is necessary first to whether judge satellite battery group
It has been accessed that, if do not accessed, satellite unpredictably power-off at this time is, it is necessary to which the power supply disconnected inside main battle array distributor is led to
Road and sampling circuit closing relay, by replacing backup power supply, and carry out simulator joint debugging work, after confirmation is errorless, again
It powers on.If failure occurs, satellite battery group has accessed, then whole star bearing power is provided by accumulator group, with outside
Power supply supply access is already off, needs, by disconnecting main battle array distributor in-line power and sampling channel selector, to disconnect logical at this time
Road cable replaces backup battery, can recover centrally connected power supply.
This item purpose technical solution is：Satellite centrally connected power supply uses the double sampled path method of dual power supply duplicate supply access, first
Model and the identical two Agilent constant-current voltage-stabilizings power supplies of production batch are first selected on power supply select as supplying electric work
Rate output equipment ensures power supply itself internal resistance state consistency；Secondly duplicate supply is designed in the circuit design of main battle array distributor to lead to
Road, double sampled access, supply access rear end are a bussed supply by reverse-filling diode, joint output.Internal circuit is adopted
With holohedral symmetry circuit structure, the independence of access control can be effectively ensured, even if a path fault, another access can be with
Normal work.Device external linking relationship is as shown in Fig. 2, power supply by the anode connecting path control device of the first power supply
1 relay of access, negative terminal connect a busbar negative terminal；The power supply of the anode connecting path control device of second power supply is led to
2 relay of road, negative terminal connect a busbar negative terminal；First power supply and the second power supply are in 1 relay of supply access, confession
2 relay rear end of electric pathway is output to a busbar anode by reverse-filling diodes in parallel；First power supply and second supplies
Power supply 1 relay of sample near-end, 2 relay of sample near-end rear end Parallel opertation to a busbar anode, complete access
Control circuit connects, whole star load connection busbar anode, negative terminal；Two passes independent control, is independent of each other.In DC voltage-stabilizing electricity
It in terms of the setting of source, sets two power supply output modes identical, is constant pressure output；Set two power work electric currents identical, no
More than over-current protection point；It is 101V to set First operating supply voltage, and it is 100.9V to set second fetus operating supply voltage, with
This ensures that First power preferentially exports, and second power supply rests on wait output mode, avoids generation power supply alternating defeated
Go out, busbar voltage ripple is caused to change.
Using Fig. 2 power supply modes, troubleshooting mode is fairly simple, as shown in Figure 4.First D.C. regulated power supply goes out
Existing overvoltage protection is exported as 0, and telemetering is abnormal when failure problems, and effect is that the output of First power supply is forbidden, it is impossible to be satellite
Power supply, second power supply can export automatically, be a bussed supply, not interfere with whole star power supply, and trouble power can be with until survey
Examination terminates to be handled.
This project technical solution inside main battle array distributor by increasing lane-wise rather than D.C. regulated power supply rear end
Direct parallel way, the electric current that can effectively evade power supply itself pour in down a chimney phenomenon；Led to inside main battle array distributor using duplicate supply
Road, it is ensured that power output stability, reliability, while meet process requirements；Double sampled access can evade single sampling
The overvoltage protection risk that path fault causes D.C. regulated power supply output rise and generates.
The content not being described in detail in description of the invention belongs to the known technology of those skilled in the art.
