I-Smart Grid System PCB Prototyping: Isikhokelo esiBanzi

Yazisa:

Njengoko umhlaba usiya kwikamva lamandla azinzileyo, ukubaluleka kweenkqubo zegridi ezikrelekrele kubonakala ngakumbi kunangaphambili. Ezi nkqubo ziphakamisa ubugcisa obuphambili bokwandisa usasazo lwamandla, ukubeka iliso kusetyenziso lwamandla nokuqinisekisa ulawulo olusebenzayo lwamandla. Embindini wezixokelelwano zegridi ezihlakaniphile licandelo elibalulekileyo: ibhodi yesekethe eprintiweyo (PCB).Kule bhlog, siza kuntywila kwiingqwalasela ezifanayo ze-PCB prototyping kumxholo wenkqubo yegridi ehlakaniphile, sijonga ubunzima bazo kunye neziphumo.

1. Ukuthembeka kunye nokuqina koyilo:

Iinkqubo zegridi ze-Smart zihlala zisebenza ngokuqhubekayo kwindawo enzima. Ke ngoko, ukuthembeka kunye nokuqina kuba yimiba ebalulekileyo ekufuneka iqwalaselwe xa kuyilwa iiprototypes zePCB kwiinkqubo ezinjalo. Amacandelo kufuneka akhethwe ngononophelo ukumelana noxinzelelo lwe-thermal, ukungcangcazela kunye nokufuma. Ubuchule bokuthengisa, ii-conformal coatings kunye ne-encapsulation nazo zinokusetyenziselwa ukwandisa ubomi bePCB.

2. Amandla kunye nomqondiso wemfezeko:

Kwiinkqubo zegridi ezikrelekrele, iiPCB zenza imisebenzi emininzi efana nokulungiswa kwamandla, unxibelelwano lwedatha, kunye nokuziva. Ukuze usebenze ngokugqibeleleyo, amandla kunye nokuthembeka komqondiso kufuneka kuqinisekiswe. Umkhondo wokulandela umkhondo, uyilo lwenqwelomoya ephantsi komhlaba, kunye neendlela zokunciphisa ingxolo kufuneka ziqwalaselwe ngononophelo. Ingqwalasela ekhethekileyo kufuneka ihlawulwe ekunciphiseni ukuphazamiseka kwe-electromagnetic (EMI) ukuthintela ukuphazamiseka kwenkqubo.

3. Ulawulo lobushushu:

Ulawulo olufanelekileyo lwe-thermal lubalulekile kwi-PCB prototyping kwiinkqubo zegridi ezihlakaniphile, apho ukusetyenziswa kwamandla kunokubaluleka. Iisinki zobushushu, ii-vents, kunye nokubekwa ngokufanelekileyo kwamalungu kunceda ukukhupha ubushushu ngokufanelekileyo. Izixhobo zokuhlalutya ezifana nesoftware yokulinganisa i-thermal inokunceda abaqulunqi bachonge iindawo ezinokuba shushu kwaye baqinisekise izisombululo zokupholisa ezona zilungileyo.

4. Landela imigangatho yokhuseleko:

Iinkqubo zegridi ze-Smart ziphatha umbane ophezulu we-voltage, ngoko ukhuseleko luphambili oluphambili. Iiprototypes ze-PCB kufuneka zihambelane nemigangatho engqongqo yokhuseleko, njengeemfuno ze-UL (Underwriters Laboratories). Ukugquma okufanelekileyo, ubuchule bomhlaba, kunye nokukhuselwa kwe-overcurrent kufuneka kuhlanganiswe kuyilo lwe-PCB ukuthintela iingozi zombane kunye nokuqinisekisa ukuthotyelwa.

5. Ukubaleka kunye nokuphucula:

Iinkqubo zegridi ezihlakaniphile ziyaguquguquka kwaye zifuna ukukwazi ukukhawulelana nokwandiswa nokuphuculwa kwexesha elizayo. Xa uyila iiprototypes zePCB kwezi nkqubo, abaphuhlisi kufuneka baqwalasele ubungakanani. Oku kubandakanya ukushiya indawo eyaneleyo yokongeza kunye nokuqinisekisa ukuhambelana nobuchwepheshe bexesha elizayo. Ukusebenzisa uyilo lwemodyuli kunye neziqhagamshelo zendalo yonke zenza lula uhlaziyo lwexesha elizayo kunye nokunciphisa iindleko zenkqubo iyonke.

6. Uvavanyo kunye nokuqinisekisa:

Ukuvavanywa ngokucokisekileyo kunye nokuqinisekiswa kweeprototypes ze-PCB kubalulekile ngaphambi kokuthunyelwa kwiinkqubo zegridi ezihlakaniphile. Ukulinganisa iimeko zehlabathi lokwenyani ngovavanyo loxinzelelo lwendalo esingqongileyo, uvavanyo olusebenzayo, kunye nohlalutyo lokungaphumeleli kunokubonelela ngemibono ebalulekileyo ekuthembekeni kunye nokusebenza kwe-PCB. Ukusebenzisana phakathi koyilo kunye namaqela ovavanyo kubalulekile ekuphuculeni umgangatho jikelele wenkqubo.

7. Ukuphucula iindleko:

Nangona kubalulekile ukuhlangabezana nazo zonke ezi ngqwalasela zingentla, ukulungiswa kweendleko akunakungahoywa. Iinkqubo zegridi ezihlakaniphile zifuna utyalo-mali olubalulekileyo, kwaye i-PCB prototyping kufuneka ijolise ekubetheni ukulingana phakathi kokusebenza kunye noqoqosho. Ukuphonononga itekhnoloji yokwenziwa kweendleko kunye nokusetyenziswa koqoqosho lwesikali kunokuncedisa ukunciphisa iindleko zemveliso.

Ukuququmbela:

I-PCB prototyping ye-smart grid systems ifuna ingqalelo ecokisekileyo kwiinkcukacha kunye nokuthotyelwa kweemfuno ezithile. Ukuthembeka, ukuqina, amandla kunye nokuthembeka komqondiso, ulawulo lwe-thermal, ukuthotyelwa kokhuseleko, ukulinganisa, ukuvavanywa kunye nokulungiswa kweendleko zizinto eziphambili zokuqwalaselwa ukuqinisekisa impumelelo yegridi ye-PCB prototyping. Ngokujongana nale miba ngononophelo, abaphuhlisi banokufaka isandla ekuphuhliseni izisombululo zamandla ezisebenzayo, ezizinzileyo kunye nezizinzileyo eziza kubumba ikamva lothungelwano lwethu lokuhambisa.
