Iiprotokholi zoQinisekiso loMgangatho kwiMveliso yeSolar Connector yokunciphisa umngcipheko

Intshayelelo

Ngaphakathi Isixhumi selanga imveliso, ukuqinisekiswa komgangatho asikokujonga ibhokisi kodwa lulawulo oluphambili lokhuseleko lombane, ixesha lokusebenza kwenkqubo, kunye nomngcipheko wewaranti. Iziphene ezincinci ekuqhekekeni, ukulungelelaniswa koqhagamshelwano, ukutywina, okanye ukukhethwa kwezinto zinokukhula zibe kukwakheka kokumelana, ukufudumala, ukungena komswakama, kunye nokusilela kwangaphambi kwexesha kuzo zonke ii-PV. Eli nqaku lichaza iiprotokholi ezinciphisa ezo mngcipheko kwinqanaba lokuvelisa, ukusuka ekuqinisekisweni kwezinto ezingenayo kunye nokuhlolwa kobukhulu ukuya kuvavanyo lombane, loomatshini, kunye nolwendalo. Abafundi baya kufumana umbono osebenzayo wendlela i-QA ecwangcisiweyo ekhusela ngayo ukuthembeka kwesixhumi, ixhasa ukuthobela, kwaye inceda abavelisi kunye namaqela eprojekthi ukuthintela ukusilela okubizayo ngaphambi kokuba izinto zifike kwicandelo.

Kutheni Ukuqinisekiswa Komgangatho Wesixhumi Selanga Kubalulekile

Ukuthembeka kwenkqubo ye-photovoltaic (PV) kuxhomekeke kakhulu kwizinto zayo ezincinci. Izihlanganisi zelanga zisebenza njengeendawo ezibalulekileyo zokudibanisa yokudluliselwa kwamandla ombane ngqo (DC) kwii-solar arrays zorhwebo, zoshishino, kunye nezixhobo. Ngaphandle kokujongwa ngokungqongqo, ezi zinto zinokuba likhonkco elibuthathaka kakhulu kwikhonkco lokuvelisa amandla, nto leyo ekhokelela kwiingozi ezinkulu zokhuseleko kunye nelahleko enkulu yemali.

Iingozi eziphambili zemveliso kunye nokungaphumeleli kwentsimi

Ukungahambelani kwemveliso kunye noxinzelelo lokusingqongileyo kuzisa umngcipheko omkhulu kufakelo lwe-PV. Iziphene eziqhelekileyo zokwenziwa ziquka ukugoba okungafanelekanga, ii-contact pin ezingalungelelananga kakuhle, kunye nezixhobo zendlu ezingaphantsi komgangatho eziwohloka ngokukhawuleza xa zichatshazelwa yi-ultraviolet rhoqo. Entsimini, ezi ziphene zibonakala njenge ukumelana okuphezulu koqhagamshelwanoIdatha yeshishini ibonisa ukuba ukuya kuthi ga kwi-30% yeengxaki ezinkulu zeenkqubo ze-PV, kuquka nemililo yombane yendawo, zivela kwi-cross-mating okanye izihlanganisi ze-DC ezineziphene apho ukumelana noqhagamshelwano kudlula umda wokhuseleko obalulekileyo we-0.5 milliohms.

Ngaphezu koko, ukujikeleza kobushushu phakathi kwamaqondo obushushu agqithisileyo, adla ngokuqala kwi -40°C ukuya kwi +85°C, kwenza kube nzima ukuqhekeka kweeplastiki ezingaphantsi komgangatho. Ukungena kwamanzi ngenxa yezitywina ze-O-ring ezingasebenziyo kunokukhokelela kwiimpazamo zomhlaba kunye nokuvalwa kwe-inverter kwangoko. Xa izihlanganisi zingagcini umlinganiselo we-IP68 kwimozulu embi, ukuqokelelwa komswakama okubangelwayo kukhawulezisa ukubola kwe-galvanic, kunciphisa kakhulu ubomi benkqubo yokusebenza kunye nokuveliswa kwamandla ngokubanzi.

Indlela yokuchaza iindlela ezisebenzayo zokuqinisekisa umgangatho

Ukuseka ukuqina iiprotokholi zokuqinisekisa umgangatho wesixhumi selanga ifuna indlela ebanzi equka lonke ixesha lokwenziwa kwemveliso. Abavelisi kufuneka bachaze iinjongo ezicacileyo nezilinganisekayo, bejolise kwizinga leziphene elingaphantsi kwe-100 parts per million (PPM) ukuqinisekisa ukuba imveliso iyasebenza kwaye ikhuselekile ebaleni.

Iiprotokholi ezisebenzayo ziyalela amaxesha athile ovavanyo, imida eyamkelekileyo yokunyamezelana, kunye neenkqubo zokusebenza ezisemgangathweni zabasebenzi bomgca wokuhlanganisa. Ngokuchaza ezi parameters kwangaphambili, amaqela olawulo lomgangatho anokutshintsha ukusuka ekusombululeni iingxaki ngokuphendula ukuya ekunciphiseni umngcipheko ngokukhawuleza. Le ndlela icwangcisiweyo iqinisekisa ukuba iqela ngalinye lemveliso liyahlangabezana neemfuno ezifunekayo zombane, zoomatshini, nezobushushu ngaphambi kokuba izixhobo zigunyaziswe ukuba ziphume kumgangatho wefektri.

Ulawulo kunye neMigangatho yoQinisekiso loMgangatho

Ukuguqula iinjongo zomgangatho ophezulu zibe ziziphumo ezibonakalayo kufuna isakhelo esicwangcisiweyo solawulo olubonakalayo. Esi sakhelo sixhomekeke kudibaniso lwetekhnoloji yokuhlolwa ephucukileyo kunye nokunamathela ngokungqongqo kwimigangatho ye-electrotechnical eyaziwayo kwihlabathi liphela.

Iindlela zokuhlola ezingenayo, ezisetyenziswayo, kunye neendlela zokugqibela zokuhlola

Ulawulo lomgangatho lusebenza kumanqanaba amathathu aphambili: ukungena, ukwenziwa, kunye nokuhlolwa kokugqibela. Ukuhlolwa kwezinto ezingenayo kuqinisekisa ukuthembeka kwezinto ezifakwayo ezingavuthwanga, ukuqinisekisa ukuba iiphini ze-copper alloy zifikelela kucoceko oluphantsi lwe-conductivity lwe-99% kwaye izindlu ze-polycarbonate zihlangabezana nezilinganiso ezithile zokutsha, ezifana nomgangatho we-UL94 V-0.

Ukuhlolwa kwangaphakathi kwenkqubo kusebenzisa i-Automated Optical Inspection (AOI) ukufumanisa ukungalingani kobukhulu ngexesha langempela kumgca wokudibanisa. Ngeli nqanaba, uvavanyo lokutsalwa kwamandla oomatshini lubalulekile; icandelo eliqhelekileyo le-4mm² Intambo yePV kufuneka imelane namandla amancinci okutsala angama-300 Newtons ukuqinisekisa ukuthembeka kwe-crimp. Okokugqibela, uvavanyo oluqinileyo lombane—kuquka uvavanyo lwe-dielectric ukumelana ne-voltage apho izihlanganisi ezidibeneyo ziphantsi kwe-6000V DC—ziqinisekisa ukumelana nokufakwa kwe-insulation kwaye zithintele ukuxinana kwe-high-voltage ebaleni.

Imigangatho, amaxwebhu, kunye neendlela zokuthelekisa

Ukuthobela imigangatho yamazwe ngamazwe akunakuxoxiswana ngako malunga nokungena kwimarike kunye nolawulo lomngcipheko. Imilinganiselo emibini ephambili elawulayo Izihlanganisi zeLanga yi-IEC 62852 kwiimarike zehlabathi nezaseYurophu, kunye ne-UL 6703 eMntla Melika. Amaqela okuqinisekisa umgangatho kufuneka agcine amaxwebhu aneenkcukacha, kuquka iingxelo zovavanyo lwezinto eziphathekayo (ii-MTR) kunye nezatifikethi zelebhu zomntu wesithathu, ukuqinisekisa ukuba iyathotyelwa imithetho rhoqo.

Ngokusebenzisa ezi ndlela zokuthelekisa, amaqela okuthenga anokuvavanya ukuba uvavanyo lwangaphakathi lomenzi luyahambelana na neemfuno ezithile zokusingqongileyo kunye nolawulo lwendawo yokufakela. Amaxwebhu afanelekileyo aqinisekisa ukuba zonke iindlela zokhuseleko ziyalandeleka kwaye ziyaqinisekiswa ngabahloli abazimeleyo.

Indlela Abavelisi kunye Nabathengi Abafanele Bayiphumeze Ngayo I-QA

Kubavelisi abavelisa izinto kunye neenkampani zobuNjineli, ukuThenga, kunye noKwakha (i-EPC) ezizithengayo, ukuphumeza isicwangciso sokuqinisekisa umgangatho esidibeneyo ngumzamo wentsebenziswano. Oku kufuna ukulungelelanisa iindlela zokuthenga kunye noxanduva oluqinileyo kwinqanaba lefektri.

Isiqinisekiso somthengisi kunye nokulandelelwa kwebhetshi

Abathengi kufuneka babeke phambili isiqinisekiso somthengisi ngokwenza uphicotho olupheleleyo lweNkqubo yoLawulo loMgangatho (i-QMS) yomenzi, ngokuqhelekileyo kuqinisekiswa isiqinisekiso se-ISO 9001 esisebenzayo. Inxalenye ebalulekileyo yale siqinisekiso kukuvavanya iziseko zophuhliso zokulandelela umboneleli ukuqinisekisa uxanduva kwizigidi zeeyunithi ezivelisweyo.

Ukulandelelana okusebenzayo kuqinisekisa ukuba isixhumi ngasinye sinokudityaniswa sibuyele kwinguqu yaso yemveliso ethile, ibhetshi yezinto eziluhlaza, kunye nomsebenzisi womatshini. Abavelisi abaphambili basebenzisa iikhowudi ze-QR ezichongiwe nge-laser okanye iinombolo ze-serial ezizodwa ngqo kwi-connector housing. Ukugcina ezi rekhodi zebhetshi ubuncinane iminyaka engama-25 kubalulekile, njengoko eli xesha lihambelana namaxesha ewaranti yokusebenza eqhelekileyo yeemodyuli ze-photovoltaic zanamhlanje, okuvumela uhlalutyo olukhawulezileyo lwemvelaphi kwimeko engaqhelekanga yokusilela kwentsimi.

Ukulinganisela iindleko, ixesha lokunika isiqinisekiso, kunye neemfuno zesatifikethi

Ukusebenzisa imigaqo-nkqubo yovavanyo ebanzi kwazisa izinto ezahlukeneyo kuqoqosho lwemveliso. Ukuphucula iziko lokuvelisa ukuze lihlangabezane nemigangatho yokuhlolwa ephezulu kudla ngokunyusa iindleko zemveliso kwangaphambili nge-3% ukuya kwi-5%. Ngaphezu koko, ukudibanisa uvavanyo olupheleleyo lokusingqongileyo kunye noxinzelelo lombane kunokwandisa amaxesha aqhelekileyo okuhanjiswa kwemveliso ngeveki e-1 ukuya kwezi-2.

Nangona kunjalo, abavelisi kunye nabathengi kufuneka balinganise olu tyalo-mali lokuqala kunye nokhuseleko lokusebenza lwexesha elide. Ukunyuka okuncinci kweendleko zeyunithi kunye nexesha lokuqalisa akunamsebenzi xa kuthelekiswa nempembelelo yezemali yokusilela kwenkqubo ngokubanzi. izinto eziqinisekisiweyo nezivavanyiweyo ngokungqongqo kunciphisa amabango ewaranti emva kokufakwa ukuya kuthi ga kwi-80%, kususa iindleko eziphezulu zokutshintshwa kweendawo ezingxamisekileyo, kwaye kukhusela imbuyekezo iyonke kutyalo-mali lwezinto zelanga ezisetyenziswa kakhulu kwiminyaka yazo emininzi.
