IMigangatho yeNkqubo yaMandla eAviation: Isitshixo ekuQinisekiseni ukuSebenza okuKhuselekileyo kweeNqwelo-moya

Ngokwandiswa kothutho lwehlabathi jikelele kunye nophuhliso olukhawulezayo lobuchwepheshe beenqwelomoya, inkqubo yamandla ezinzileyo ibe yinto ephambili ekuqinisekiseni ukusebenza okuqhubekayo kweenqwelomoya.Iiyunithi ze-aviation zamazwe ngamazwe ziphuhlise uluhlu lwemigaqo ye-aviation, efana ne-MIL-STD-704F, RTCA DO160G, ABD0100, GBB181A, njl.., ejolise ekulinganiseni iimpawu zombane wezixhobo zombane zenqwelomoya ukuqinisekisa ukuba inqwelo-moya isenokuthi isebenze ngokuqhelekileyo phantsi kweemeko ezahlukeneyo zobonelelo lwamandla.

I-Aircraft Inkqubo yonikezelo lwamandla ingundoqo yenqwelo-moya, imeko yayo yokusebenza inokwahlulwa ibe ngamathandathu: Eqhelekileyo , Engaqhelekanga , Ukudluliselwa , Emergency , Ukuqala kunye nokungaphumeleli kwamandla . La mazwe anezinto ezithile zokuvavanya ukuqinisekisa ukuba izixhobo zihlangabezana noluhlu lwemigangatho yokhuseleko echazwe kwimimiselo yeenqwelomoya, izixhobo ze-Avionics eziNxulumeneyo ezifana neeyunithi ze-Auto Transformer, iiyunithi ze-Transformer Rectifier, ii-avionics, iinkqubo ze-Cabin Entertainment, njl njl. imigangatho yeenkqubo zonikezelo lwamandla eenqwelomoya, ezahlulahlula zibe zintlobo ezimbini: AC kunye neDC.Uluhlu lwe-AC lwe-voltage yi-115V / 230V, uluhlu lwe-voltage ye-DC yi-28Vdc ~ 270Vdc, kwaye i-frequency ihlukaniswe yaba yimida emithathu: 400Hz, 360Hz ~ 650Hz, kunye ne-360Hz ~ 800Hz.

Imimiselo ye-MIL-STD-704F ibandakanya i-SAC (isigaba esisodwa 115V / 400Hz), i-TAC (isigaba sesithathu 115V / 400Hz), i-SVF (isigaba esisodwa 115V / 360-800Hz), i-TVF (isigaba sesithathu 115V / 360 ), kunye ne-SXF (isigaba esisodwa 115V/360-800Hz) /60Hz), i-LDC (28V DC), kunye ne-HDC (270V DC). Inkampani yazise uluhlu lwezixhobo zombane ze-AC ezicwangcisiweyo ezilinganisa kwaye zincedisa kuvavanyo oluninzi kumgangatho we-MIL-STD-704 kunye noluhlu olubanzi lweevoltages eziphumayo kunye neefrikhwensi, ukubonelela abasebenzisi ngeendlela ezahlukeneyo zokuvavanya ukuqinisekisa ukuthotyelwa kwamandla enqwelomoya. iinkqubo.

Kwinqwelomoya kunye nezixhobo ezinxulumene nokhuselo, i-AC 400Hz kunye ne-DC 28V zizinto ezifunekayo zombane wokungenisa. Kwiminyaka yakutshanje, ngenxa yophuhliso olukhawulezayo lwetekhnoloji, i-800Hz kunye ne-DC 270V ziyimfuneko yesizukulwana esitsha. Xa kuthelekiswa neenkcukacha zesiqhelo zemizi-mveliso okanye zamandla oluntu, ukuhamba ngenqwelomoya kunye nokhuseleko kuneemfuno ezingqongqo zobonelelo lwamandla. Ukongeza ekuboneleleni ngombane ococekileyo, uzinzo olululo lwevoltheji kunye nokugqwetheka, bakwaneemfuno ezithile zokhuseleko, ukugcwala, kunye nokuxhathisa impembelelo. Kukwafuneka bathobele i-MIL-STD-704F, eluvavanyo olukhulu kubaboneleli bamandla.

Xa inqwelomoya ifakwe, unikezelo lwamandla omhlaba luya kuguqulwa lube yi-400HZ okanye i-800Hz ukubonelela ngenqwelomoya ukugcinwa okuhambelanayo, unikezelo lwamandla lwemveli lubonelelwa kakhulu yijenereyitha, kodwa ngenxa yendawo, ingxolo, ukonga amandla kunye nokuzinza kunye nezinye ezinxulumene nazo. izinto, abasebenzisi abaninzi ngokuthe ngcembe batshintshela kwi-static unikezelo lwamandla. YenkampaniUchungechunge lwe-AMF lunokubonelela nge-400Hz okanye i-800Hz ezinzileyo, kunye nebakala lokukhusela i-IP54, umthamo ogqithisiweyo unokumelana ngaphezu kokuphindwe kabini, ulungele ukunikezelwa kwamandla omhlaba kwi-airborne okanye izixhobo zomkhosi, ngaphandle okanye i-hangar ingasetyenziswa.

Imisebenzi ekhoyo

1. Umthamo ophezulu wokulayisha kunye nenqanaba eliphezulu lokukhusela

Uchungechunge lwe-AMF lunikezelo lwamandla ombane ophakathi olulungiselelwe ukusetyenziswa ngaphandle, umgangatho wokukhusela ufikelela kwi-IP54, umatshini wonke ukhuselwe kathathu, kwaye amacandelo aphambili aqiniswa ukuqinisekisa ukusetyenziswa kwiindawo ezilukhuni. Ukongeza, kwimithwalo yokufundisa efana neenjini okanye iicompressors, uchungechunge lwe-AMF lunomthamo ophezulu wokulayishwa kwe-125%, 150%, 200%, kwaye unokwandiswa ukuya kuma-300%, alungele ukujongana nemithwalo ephezulu yokuqala yangoku, kwaye iyancipha kakhulu. iindleko zokufumana.

2. Ubuninzi bamandla aphezulu

AMF series intermediate frequency unikezelo lwamandla, kunye nobukhulu obuphambili kushishino kunye nobunzima, inoxinano lwamandla aphezulu kunonikezelo lwamandla kwimarike jikelele, umthamo xa kuthelekiswa ukuya kuma kwi-50% umahluko, umahluko ubunzima ukuya kuma-40%, ukuze ufakelo imveliso. kunye nokuhamba, ukuguquguquka ngakumbi kwaye kulula.

Ukuba kukho imfuno yeDC,Uluhlu lwe-ADS lunokubonelela nge-28V okanye i-270V DC yombane, kunye nokumelana nefuthe elinamandla kunye nomthamo wokulayisha, kwaye isetyenziswe ngokubanzi ukunika amandla kwizixhobo ezinxulumene nemoto.

Imisebenzi ekhoyo

1. Unikezelo lwamandla omkhosi ngeenqwelomoya

I-ADS inokubonelela ngombane ozinzileyo we-DC kunye nesakhono esinamandla sokulayisha, esilungele umzi-mveliso kunye nokwamkelwa kwezixhobo zomoya kwishishini lokuvelisa kunye nokugcinwa kwenqwelomoya.

2. Umthamo wokugcwala

I-ADS inomthwalo ongaphezulu ukuya kuthi ga kathathu umlinganiselo wangoku kwaye unokumelana nokothuka okuqinileyo, okwenza ukuba ilungele ukuqala, ukuvavanywa kwemveliso okanye ukugcinwa kwemithwalo yokungenisa, efana neenjini zenqwelomoya, iijenereyitha kunye neemveliso ezinxulumene nemoto.
