Ukubaluleka kweSiqinisekiso seTUV kwiiSolar Connectors kwiiMarike zeHlabathi

Kwiiprojekthi zelanga zehlabathi, umgangatho wesixhumi asinto incinci: uchaphazela ngqo ukhuseleko, ixesha lokusebenza kwenkqubo, ukwamkelwa kweinshorensi, kunye nokufikelela kwimarike. Izihlanganisi zeLanga Nika abavelisi, ii-EPC, kunye nabathengi ubungqina obuzimeleyo bokuba ezi zinto ziyahlangabezana nemigangatho eyaziwayo yokusebenza kombane, ukuqina, kunye nokumelana nokusingqongileyo phantsi kweemeko ze-PV ezinzima. Eli nqaku lichaza isizathu sokuba isiqinisekiso se-TUV sibalulekile kwiimarike zamazwe ngamazwe, zeziphi iingozi ezinokuziswa zizihlanganisi ezingaqinisekiswanga, kunye nendlela isiqinisekiso esixhasa ngayo ukuthotyelwa kwemithetho, ukuzithemba kwabatyali-mali, kunye nokuthembeka kwexesha elide kuzo zonke izixhobo zombane, zorhwebo, kunye neendawo zokuhlala.

Kutheni ii-Solar Connectors eziqinisekiswe yi-TUV zibalulekile

Njengoko ukufakwa kwe-solar photovoltaic (PV) yehlabathi jikelele kukhula ukuze kuhlangatyezwane neenjongo zamandla avuselelekayo, ulwakhiwo kunye nomgangatho wombane wecandelo ngalinye lenkqubo uba ngundoqo ngakumbi. Izihlanganisi zelanga zisebenza njengemithambo ebalulekileyoyothumelo lwamandla, edibanisa ngaphandle komthungo iiphaneli ngazinye, abaxubi beentambo, kunye nee-inverters eziphambili. Ezisebenza ngokuqhubekayo kwiindawo ezingaphandle ezinzima—ukusuka kwiintlango ezomileyo ukuya kwiindawo ezifumileyo zonxweme—ezi zinto zijongene noxinzelelo olukhulu lobushushu kunye nombane. Iinkqubo ze-PV zanamhlanje ezisetyenziswayo zihlala zisebenza kwiivolthi eziphakamileyo ukuya kuthi ga 1500V DC, okwenza nakuphi na ukusilela kwenxalenye kube yingozi enkulu yokhuseleko kunye nomlilo kunokuba kube kukuphazamiseka nje kokusebenza.

Ukuze kuncitshiswe le mingcipheko, imboni yelanga yehlabathi ixhomekeke kwimibutho yovavanyo oluzimeleyo kunye neziqinisekiso ukuqinisekisa ukhuseleko lwezixhobo. Isiqinisekiso seTechnischer Überwachungsverein (TUV) simi njengomgangatho wegolide obalaseleyo kwihlabathi liphela wezixhobo zePV. Ukuqinisekisa ukunyaniseka Izihlanganisi zelanga eziqinisekisiweyo yiTUV iqinisekisa ukuba izixhobo zonxibelelwano zidlulile kwiindlela zovavanyo ezingqongqo nezisemgangathweni. Oku kubonelela abaphuhlisi beeprojekthi, abaxhasi bezemali, kunye nabakhi be-EPC (Ubunjineli, ukuThenga, kunye noKwakha) ubungqina obunokuqinisekiswa, bomntu wesithathu bokuqina, ukhuseleko, kunye nokusebenza kwexesha elide kwezixhobo.

Iingenelo zokhuseleko, ukuthembeka, kunye nokuthobela imithetho

Iingenelo eziphambili zokusebenzisa izixhobo zoqhagamshelo eziqinisekisiweyo zigxile ekuthinteleni umlilo, uzinzo lombane, kunye nokuthotyelwa kwemithetho engqongqo. Umgangatho ophezulu, izihlanganisi eziqinisekisiweyo Zenzelwe ukugcina ukumelana okuncinci kakhulu kokunxibelelana okungaphantsi kwe-0.5 milliohms kuyo yonke iminyaka engama-25 yeprojekthi yelanga. Olu kumelana okuphantsi kakhulu lubalulekile kuba ukumelana okuphezulu kokunxibelelana kuvelisa ubushushu obugqithisileyo phantsi kwemithwalo ephezulu yamandla ombane—imbangela ephambili yeziphene ezinkulu ze-DC arc kunye nemililo elandelayo yelanga. Ngaphezu koko, abaqhubi begridi, oomasipala, kunye nababhali beinshurensi bayanyanzela ukuba kuthotyelwe imithetho engqongqo ye-TUV njengemfuneko engenakuphikiswana yokuvunywa kweprojekthi kunye nokugubungela uxanduva, nto leyo enika izinto ezingaqinisekiswanga uxanduva olukhulu lwezemali.

Abathengi be-scope yesatifikethi kufuneka baqinisekise

Amaqela okuthenga kunye neenjineli zoyilo kufuneka zijonge ngaphaya kwelogo ye-TUV esisiseko kwaye ziqinisekise ngononophelo umda othile wesiqinisekiso. Izihlanganisi kufuneka ziqinisekiswe ngokwemigangatho engqongqo yeshishini efana ne-IEC 62852 okanye i-EN 50521, echaza iimfuno zokusebenza ezibalulekileyo kwizicelo ze-DC ezinzima kwiinkqubo ze-PV. Abathengi kufuneka baqinisekise ukuba esi siqinisekiso siquka ukunyamezelana okubalulekileyo kokusingqongileyo, kubandakanya ukumelana ne-UV ixesha elide, ukhuseleko lokungena kwe-IP67 okanye i-IP68 emanzini kunye nothuli olucolekileyo, kunye nokunyamezela ubushushu kububanzi obufunekayo bobushushu obuphakathi kwe--40°C ukuya kwi-+85°C. Ukuqinisekisa ezi parameters kuqinisekisa ukuba izixhobo zihambelana neemfuno ezithile zokusingqongileyo zendawo yokufakela.

Izihlanganisi zelanga eziQinisekisiweyo yi-TUV vs ezingaQinisekisiweyo

Imarike yehlabathi yezinto ze-PV izaliswe ziindlela ezingabizi kakhulu nezingaphantsi komgangatho ezilingana kakhulu nohlobo lwezihlanganisi ezisemgangathweni zoshishino kodwa zingenabo ubunjineli obusisiseko, ukuchaneka, kunye nomgangatho wezinto eziphathekayo. Nangona ukutshintsha izihlanganisi ezingaqinisekiswanga kunokubangela ukonga okuncinci kweendleko kwangaphambili ngexesha lokuthenga, iziphumo zemali kunye nokusebenza kwexesha elide zimbi kakhulu. Ukwanda kweendleko zeMisebenzi kunye noLondolozo (O&M), ixesha lokungasebenzi kwenkqubo, kunye nokutshintshwa kwezixhobo kulula ukugqitha ukonga kokuqala. Ukuqonda umahluko wobugcisa phakathi kweendlela eziqinisekisiweyo nezingenakuqinisekiswa kubalulekile kulawulo olusebenzayo lomngcipheko kunye nokukhuselwa kweeasethi.

Umahluko ophambili kuvavanyo kunye nokuqina

Umahluko omkhulu phakathi kwezi mveliso ukwimeko yobunzima kunye nobunzulu beendlela zazo zokuvavanya. Ukuvunywa kwe-TUV kufuna izinto ezithile ukuze zisinde kuvavanyo lobomi olukhawulezileyo (HALT) ukuze kuxelwe ukusetyenziswa gwenxa kokusingqongileyo amashumi eminyaka. Oku kuquka uvavanyo lobushushu obumanzi lweeyure ezili-1000 kwi-85°C kunye nomswakama ohambelanayo we-85%, uvavanyo oluqinileyo lwe-salt mist corrosion kwizicelo zaselunxwemeni, kunye novavanyo oluncinci lwe-200-cycle thermal shock ukusuka kwi--40°C ukuya kwi-+85°C. Ngokwemishini, izihlanganisi eziqinisekisiweyo kufuneka zinyamezele amandla amancinci okugcina intambo angama-89 Newtons ngaphandle kokubonisa ukuwohloka kombane okanye koomatshini. Ngokwahlukileyo koko, ezinye iindlela ezingaqinisekiswanga zihlala zisebenzisa iiplastiki ezisetyenzisiweyo eziphantsi kunye nee-alloys zobhedu ezikumgangatho ophantsi eziwohloka ngokukhawuleza phantsi kokuvezwa rhoqo kwe-UV, zihlala zingaphumeleli kuvavanyo lokugcinwa koomatshini okanye zilahlekelwe zizitywino zazo ezingangeni manzi kwiinyanga zokuqala ezingama-24 ukuya kuma-36 zokusetyenziswa kwentsimi.

Iikhrayitheriya zovavanyo lobugcisa nolawulo

Ukuvavanya izinto ngokungakhethi cala kufuna uhlalutyo oluhambelanayo lwemida yobugcisa kunye neenkcukacha zezinto eziphathekayo. Izinto eziqinisekisiweyo ziqinisekisa imilinganiselo yokusebenza esisiseko apho izinto ezingaqinisekiswanga zihlala zingaphumeleli ukuhlangabezana nayo, ingakumbi phantsi kweemeko zomthwalo ophezulu. Itheyibhile engezantsi ichaza iikhrayitheriya zovavanyo ezisemgangathweni ezahlula i-hardware evunyiweyo, esebenza kakhulu kwezinye iindlela ezingaphantsi komgangatho:

Indlela yokufumana nokuqinisekisa ii-TUV-Certified Solar Connectors

Ukuchonga umthengisi othembekileyo wezinto ze-PV ifuna imigaqo engqongqo yokufaneleka kwabathengisi kunye novavanyo olucokisekileyo. Ngenxa yokuba iziqinisekiso zomgunyathi, iingxelo zovavanyo ezitshintshiweyo, kunye nokusetyenziswa kwelogo engagunyaziswanga kuhlala kuyimingeni eqhubekayo kwikhonkco lobonelelo lwelanga lwehlabathi, abathengi kufuneka basebenzise amanyathelo okuqinisekisa aqinileyo ngaphambi kokukhupha ii-odolo zokuthenga. Indlela ecwangcisiweyo nebhalwe phantsi kakhulu yokufumana ikhusela ukuthembeka kweprojekthi iyonke, iqinisekisa ukuthotyelwa kwemithetho, kwaye iqinisekisa ukuqhubeka kokusebenza kwexesha elide ubomi bempahla yelanga.

Amanyathelo okuqinisekisa ukulandeleka kunye neziqinisekiso zefektri

Inyathelo lokuqala lokuqinisekisa ngokupheleleyo kukumisela ukulandeleka okupheleleyo kwekhonkco lokubonelela.
