A Idivayisi Evikelayo Yokuhlinza (SPD) iyingxenye ebalulekile ezinhlelweni zikagesi zesimanje, eziklanyelwe ukuvikela izinto zokusebenza kuma-voltage adlulayo. Lezi zikhathi ezidlulayo, ngokuvamile ezibangelwa ukushaywa kombani noma ukushintsha kwegridi, zingadala ukuqhuma okukhulu okungazelelwe nokukhulu. Umsebenzi oyinhloko we-SPD uwukukhawulela lokhu kugaywa kukagesi okwedlulele futhi kuphambukise amandla akhuphukayo adlulele phansi, ngaleyo ndlela kuvinjwe umonakalo emishinini kagesi ebucayi nokuqinisekisa ukuqhubeka kokusebenza. Indima yayo ibalulekile ekulawuleni ubungozi okuphelele kukho kokubili ukufakwa kwezindawo zokuhlala nezohwebo.

A I-Miniature Circuit Breaker isebenza njengengxenye ebalulekile yokuvikela okuzenzakalelayo ngaphakathi kwezinhlelo zokusabalalisa ugesi. Umgomo wayo wokusebenza uncike ezindleleni ezishisayo nezikazibuthe ukuze kutholwe izimo zamanje ezingavamile. Ngemva kokuhlonza amaphutha aqhubekayo e-overcurrent noma short-circuit, idivayisi iphazamisa isekethe ngokushesha. Lesi senzo esisheshayo sivimbela ukulimala okungaba khona ekufakeni izintambo kanye nezinto zokusebenza ezixhunyiwe. Idizayini eyisisekelo iqinisekisa kokubili ukuphepha kokusebenza nokwethembeka kwesistimu.

Ezinhlelweni zikagesi zanamuhla, ikakhulukazi ekusetshenzisweni kwelanga nezimboni, indima yokuvikela isifunda ibaluleke kakhulu. I-Dc Fuse iyingxenye ebalulekile edizayinelwe ukuphazamisa amandla ngokuphephile phakathi nemicimbi ye-overcurrent noma ye-short-circuit. Isibambi sefuse sochungechunge lwe-BYPV-63 simele isisombululo esikhethekile salezi zindawo ezinogesi ophezulu we-DC, esihlinzeka ngesisekelo esivikelekile nesithembekile sesici esibalulekile se-fuse. Idizayini yayo igxile ekuqinisekiseni ukuphepha kwesistimu nobuqotho bemishini ngokwenza kube lula ukusebenza kahle kwefuse.

Ukuthembeka nokusebenza kahle kwesistimu ye-photovoltaic kuncike kakhulu ekusebenzeni kwezingxenye zayo zokuxhuma. I-Pv Connector iyisixhumi esibonakalayo sikagesi esikhethekile esiklanyelwe ukudala izixhumanisi ezivikelekile nezimelana kancane ngaphakathi kwe-solar. Uchungechunge lwe-PV-BY-03, uhlobo olufakwe kwiphaneli, lwenzelwe ukufeza le ndima, luhlinzeka ngendawo yokuxhumana eqinile yokuhlanganisa amandla asuka kumaphaneli amaningi noma axhunywe kuma-inverter. Idizayini yayo ibeka phambili ukuzinza kokusebenza kwesikhathi eside ngaphansi kwezimo eziyinselele ezivamile zokufakwa kwelanga.

I-Miniature Circuit Breaker (MCB) iyingxenye ebalulekile ekufakweni kukagesi kwesimanje, ehlinzeka ngokuvikeleka okubalulekile kumaphutha adlulele kanye nawesekethe emfishane. Nakuba i-MCB ngokwayo iyisivikelo esiphelele, ukusebenza kwayo kunganwetshwa kakhulu ngohlu lwezinsiza ezikhethekile. Lezi zingxenye zenzelwe ukuhlanganisa ngaphandle komthungo ne-core breaker, zinikeza ukulawula okuthuthukisiwe, ukuqapha, namakhono okuphepha kusistimu yokuphatha kagesi eqinile.

Ukusebenza okuphephile nokusebenza kahle kwesistimu ye-photovoltaic (PV) kuncike ezingxenyeni eziqinile eziklanyelwe izinhlelo zokusebenza zamanje (DC) eziqondile. Isici esibalulekile ekusetheni okunjalo yi-PV Isolator Switch, idivayisi eyakhelwe ngokukhethekile izidingo ezihlukile zokukhiqiza amandla elanga. Isebenza njengendawo yokunqamula mathupha, evumela ukuhlukaniswa kwamasekhethi kagesi ukuze agcinwe, afakwe, noma ngesikhathi sezimo eziphuthumayo, ngaleyo ndlela aqinisekise ukuphepha kwabasebenzi kanye nemishini.
