(Main)Space engineering - Electrical design and interface requirements for power supply
Space engineering - Electrical design and interface requirements for power supply
The target applications covered by this standard are all missions traditionally provided with power distribution and protection by LCLs/RLCLs (science, earth observation, navigation) with exclusion of telecom applications which are traditionally provided with power distribution and protection by fuses.
The present standard applies to power distribution by LCLs/RLCLs for power systems, and in general for satellites, required to be Single Point Failure Free.
The present standard document applies exclusively to the main bus power distribution by LCLs/RLCLs to external satellite loads.
Internal power system protections of LCLs/RLCLs are not covered.
Paralleling of LCLs to increase power supply line reliability is not covered by the present standard, since this choice does not appreciably change the reliability of the overall function (i.e. LCL plus load).
In fact, a typical reliability figure of the LCL (limited to the loss of its switch ON capability) is 20 FIT or less.
If the load to be connected to the LCL line has a substantial higher failure rate than this, it is not necessary to duplicate the LCL to supply that load.

Vesoljska tehnika - Električna zasnova in zahteve vmesnika za napajalna omrežja
Vse ciljne aplikacije, zajete v tem standardu, so misije, ki so običajno zagotovljene z distribucijo električne energije in zaščito z omejevalniki LCL/RLCL (znanost, zemeljska opazovanja, navigacija), razen telekomunikacijskih aplikacij, ki so običajno zagotovljene z distribucijo električne energije in zaščito z varovalkami.
Ta standard se uporablja za distribucijo električne energije z omejevalniki LCL/RLCL za napajalne sisteme in na splošno za satelite, ki morajo biti brez enotočkovnih napak.
Ta dokument se uporablja izključno za distribucijo električne energije prek glavnega vodila z omejevalniki LCL/RLCL za zunanja bremena satelita.
Notranja zaščita napajalnih sistemov omejevalnikov LCL/RLCL ni zajeta.
Vzporedna vezava omejevalnikov LCL za povečanje zanesljivosti oskrbe z električno energijo ni zajeta v tem standardu, saj ta izbira ne spremeni znatno zanesljivosti celotne funkcionalnosti (tj. omejevalnika LCL z bremenom).
Običajna vrednost zanesljivosti omejevalnika LCL (omejena na izgubo zmogljivosti vklopa stikala) je 20 FIT ali manj.
Če ima breme za povezavo z linijo omejevalnika LCL znatno višjo stopnjo napake v primerjavi z omenjeno, podvojevanje omejevalnika LCL za napajanje tega bremena ni potrebno.
