Iintlobo eziphezulu zoKhuseleko lokuKhuthazwa kweZikhundla Zonke iZiko kufuneka liziqonde

Ndihlala ndiziva uxinzelelo xa ndibona indlela okulula ngayo ukuqhuma okukodwa okunokuvala imveliso, ngoko ke ndisoloko ndikhangela into ethembekileyo Isixhobo sokukhusela ukugqumaukuhlala ukhuselekile.

Isixhobo Esikhuselayo Sokugqobhoza Sikhusela iinkqubo zombane ngokususa i-voltage engaphezulu kwizixhobo, sinciphise impembelelo yokugqobhoza okubangelwa ngumbane, iziganeko zokutshintsha, okanye ukuphazamiseka kwegridi. Sithintela ukugqobhoza okuyingozi, sizinzise inkqubo, kwaye sinciphisa umngcipheko wokungaphumeleli kwezixhobo, ngakumbi kwiindawo zoshishino apho ixesha lokungasebenzi libaluleke kakhulu.

Xa ndithetha nabaphathi bokuthenga abanjengoJeff, ndiyazi ukuba bafuna iimpendulo ezicacileyo kunye neziphumo eziqikelelweyo. Ngoko ke kweli nqaku, ndichaza iintlobo zokhuseleko lokushushuluza ekufuneka zonke iziko ziqonde kunye nendlela esebenza ngayo.

Indlela iSekethe yokuSusa iSurge ekhusela ngayo iinkqubo zombane

Ndisoloko ndixhalabile ngee-spikes ezifihlakeleyo ngaphakathi kwenkqubo yamandla, ngoko ke ndixhomekeke kwisekethe elungileyo yokunciphisa i-surge ukuze ndiphephe ixesha elibi lokungasebenzi kwindawo yam.

Isekethe yokuthintela ukuvuza ikhusela iinkqubo zombane ngokufunxa okanye ukuhambisa i-voltage engaphezulu kwiindawo ezifana nee-MOV, iityhubhu zokukhupha igesi, kunye nee-diode zeTVS. Ilinganisela umthwalo wombane kwaye ithintele ukunyuka ngequbuliso ekonakaliseni izixhobo ezibuthathaka kwiindawo zoshishino okanye zorhwebo.

Iisekethe zokunciphisa ukuxinana zisisiseko sayo yonke i-SPD ethembekileyo esetyenziswa kwiifektri. Xa ndivavanya izisombululo ze-SPD zoshishino kubathengi abakhathalele uzinzo kunye ne-TCO, ndihlala ndithelekisa izinto zangaphakathi kuba zimisela ubomi kunye nexesha lokuphendula.

Nantsi uthelekiso olulula olubonisa iindawo eziphambili zeesekethe zokunciphisa uxinzelelo:

Ngenxa yokuba ndidibana neendawo ezahlukeneyo zokuxinana kwamanzi kwimizi-mveliso, ndijonga i-clamping voltage kunye ne-maximum discharge current. Ezi zinto zichonga ukuba ukhuseleko lokushushu ngamandla kwiifektriinamandla ngokwaneleyo okusingatha iindawo ezinzima ngombane okanye iigridi zezixhobo ezingazinzanga.

Kwiifektri ezininzi endisebenza nazo, ingakumbi e-USA nase-India, ndiqaphela ukuba umngcipheko omkhulu kukukhanya okungangqalanga. Xa oku kusenzeka, i-MOV-only suppressor inokwehla ngokukhawuleza. Yiyo loo nto abathengisi abakumgangatho ophezulu abafana ne-leikexing besebenzisa isakhiwo esixutyiweyo esidibanisa i-MOV + GDT ubomi benkonzo ende.

Xa ndinceda amaqela okuthenga ahlole ababoneleli, ndisoloko ndibacebisa ukuba bajonge la manqaku mathathu:

Ngoyilo olulinganiselayo lwe-suppressor, i-SPD isebenza ngcono, ihlala ixesha elide, kwaye ikhusela rhoqo. Oku koko abaphathi bokuthenga abanjengoJeff bakuxabisa kakhulu—ukuqikelelwa kwangaphambili.Ukuze uphonononge izixhobo zokukhusela ukugqobhoza kwemizi-mveliso ngeedizayini ze-MOV+GDT ezixutyiweyo, ungajonga iimveliso zethu zokukhusela ukugqobhoza kwemizi-mveliso ukuze ufumane iinkcukacha zobugcisa ezithe vetshe.

Indlela uMkhuseli Wokugquma Osebenza Ngayo Ukuthintela Iingozi ZeVolthi Eziyingozi

Ndibone oomatshini beqalisa ngokutsha ngequbuliso ngenxa yokunyuka kwamandla ombane, ngoko ke ndisebenzisa izikhuseli ze-surge ukugcina inkqubo yam izinzile.

Isithinteli sokunyuka kwegesi sisebenza ngokufumanisa amanqanaba ombane angaqhelekanga kwaye sithumele amandla agqithisileyo kwinkqubo yokumisa umhlaba ngoko nangoko. Sinciphisa amandla okujika kwesinyithi ngaphambi kokuba sifikelele kwizixhobo, sithintele ukugqithiswa kakhulu, iingozi zomlilo, okanye umonakalo wesekethe kwizityalo zoshishino.

Xa ndichazela abathengi oku, ndichaza oku njenge "valve yokukhulula uxinzelelo" yombane. I-SPD iyasiva isantya esiyingozi kwaye ngoko nangoko ivula indlela ekhuselekileyo eya emhlabeni.

Ukuze oku kucace gca, nantsi indlela elula yokuphendula kwe-SPD yezemizi-mveliso:

Ndikwajonga neeparameter ezintathu eziphambili nanini na xa ndikhetha isikhuseli se-surge kwifektri:

1.Ubuninzi bokuKhutshwa koMbane (Imax)
Amaxabiso aphezulu athetha ukhuseleko olungcono lombane.

2.Inqanaba loKhuseleko lweVolthi (Phezulu)
I-Lower Up ithetha izixhobo ezikhuselekileyo.

3.Ixesha Lokuphendula
Ukusabela ngokukhawuleza kuthintela umonakalo omncinci obulala kancinci iimoto kunye nee-PLC.

Ngokwamava am, ukuthembeka kwexesha elide kudla ngokuxhomekeka kakhulu kulawulo lobushushu kune-peak current. Abavelisi abalungileyo basebenzisa izixhumi zobushushu ukuthintela ubushushu obugqithisileyo be-MOV. Oku kuthintela imo enkulu yokusilela kwe-SPD—ukubaleka kobushushu.

Xa uJeff endicela iingcebiso kubathengisi, ndisoloko ndikhetha iimpawu ezisebenzisa i-QC engqongqo kunye nokufunyanwa kwezinto ezinokuqikelelwa, kuba ukunyuka kwamandla ombane akuxoleli ulawulo lomgangatho olubuthathaka.

Ukukhetha uMkhuseli oLungileyo weePaneli ze-Circuit Breaker

Ndidla ngokuziva ndixinezelekile xa ndikhetha i-surge protector yephaneli exakekileyo apho yonke isekethe ibonakala ibalulekile.

Isikhuselo sokunyuka esifanelekileyo sephaneli yesiphazamisi sesekethe kufuneka sihambelane nevolthi yenkqubo, udidi lokunyuka, kunye nendawo yokufakela. Iiyunithi ze-SPD zohlobo 1, uhlobo 2, kunye nohlobo 3 zikhusela amanqaku ahlukeneyo enkqubo, ziqinisekisa ukhuseleko lokunyuka oluneeleya kunye nokusebenza okuzinzileyo kwemizi-mveliso.

Xa ndivavanya ii-SPD zephaneli zabathengi, ndihlala ndilandela indlela yokukhusela enee-layered:

Ukuba ufuna uthelekiso olunzulu, ndichaza umahluko phakathi kweeyunithi ze-SPD zohlobo 1 kunye nohlobo 2 kwisikhokelo sokukhetha i-SPD esineenkcukacha.

Kwimizi-mveliso emikhulu, ndicebisa i-SPD yokudibanisa uhlobo 1 okanye uhlobo 2. Oku kunika ukhuseleko oluqikelelweyo ngaphandle kokuqikelela.

Iiphaneli ze-breaker kwimizi-mveliso zihlala zijongene nokutshintshatshintsha okuvela kwiimoto, ii-compressor, oomatshini bokuwelda, kunye neenkqubo ze-HVAC. Ezi ntshukumo zangaphakathi zenzeka rhoqo kakhulu kunombane, ngoko ke i-SPD yepaneli enokunyamezelana okunamandla kombane okuqhubekayo ibalulekile.

Ndiqaphele ukuba izibonelelo eJamani naseFransi zigxila kakhulu kwimithetho yokulungelelanisa efana ne-IEC 61643-11. Ukulandela le mithetho kuqinisekisa ukuba ii-SPD ezisezantsi neziphezulu azingqubani.

Xa abaphathi bokuthenga becela iingcebiso kum, ndisoloko ndigxininisa oku:

1.Khetha ii-SPD ezineempawu ezicacileyo zesiphelo.

2.Sebenzisa iibhasi zekopolo xa kunokwenzeka.

3.Qinisekisa ukuba ukumelana komhlaba kuphantsi ngokwaneleyo ukuze kukhutshwe amanzi ngokukhawuleza.

4. Ziphephe ii-SPD ezingenalo ukhuselo lokususwa kobushushu.

Useto lwe-SPD lwephaneli ye-breaker oluyilwe kakuhle lunokugcina umgca wemveliso uzinzile iminyaka.
