Intsingiselo yoMbane ye-SPD kunye nesizathu sokuba ibalulekile ekuKhuselweni kokuKhuphuka

Ndihlala ndiziva ndixinezelekile xa ndibona iinkqubo zamandla zisebenza ngaphandle kwesixhobo esifanelekileyo sokukhusela i-Surge kuba ndiyazi ukuba i-spike enye ingavala zombini izindlu kunye neefektri ngoko nangoko.

Intsingiselo yombane ye-SPD sisixhobo esijika ii-voltage spikes eziyingozi ziye emhlabeni ukuze ukuvuza kungonakalisa izixhobo. Sikhusela iinkqubo zamandla kwizibane, ukutshintsha ii-transients, ukuphazamiseka kwegridi, kunye nokuvuka kwangaphakathi okwenzeka yonke imihla emakhaya, kwizakhiwo zorhwebo, nakwizakhiwo zoshishino.

Njengoko iinkqubo zamandla zisiba nzima ngakumbi, ndisoloko ndifumanisa ukuba ukuqonda ii-SPDs linyathelo lokuqala lokwakha isicwangciso sokukhusela esithembekileyo. Ngoko ke mandihambe ngesihloko ngasinye esibalulekileyo ngendlela ecacileyo nesebenzayo.

Indlela i-220 Surge Protector ethintela ngayo umonakalo kwiindawo zokuhlala nakwimizi-mveliso

Ndiziva ndingakhululekanga nanini na xa ndibona inkqubo ye-220 V ngaphandle kokhuseleko olufanelekileyo, kuba zombini izindlu kunye neefektri zinemithwalo ebuthathaka enokusilela ngokulula xa kunyuka ngequbuliso.

Isithinteli sokushushuluza esingu-220 sithintela umonakalo ngokufunxa nokuthumela i-voltage engaphezulu ngaphambi kokuba ifikelele kwizixhobo okanye izixhobo. Sizinzisa umgca, sikhusela kwizibane, kwaye sinciphisa ukushukuma kwangaphakathi okuxhaphakileyo emakhayeni nakwiindawo zoshishino.

Xa ndisebenza nabaphathi bokuthenga okanye iinjineli zombane, ndidla ngokuchaza ukuba inkqubo ye-220 V yenye yezona nqanaba zixhaphakileyo ze-voltage kwihlabathi liphela. Oku kuthetha ukuba yenye yezona ndawo zilula zokusilela kombane ukuba Isixhobo sokukhusela ukugquma ayikho. Ndibone iifektri zilahlekelwa ziimoto, ii-PLC, kunye neesensa kuba nje bezithembele kakhulu kwigridi.

Kwizicelo zasekhaya, abasebenzisi abaninzi bacinga ukuba ngumbane kuphela obangela umonakalo. Nangona kunjalo, ndivavanye iinkqubo ezininzi kwaye ndifumanise ukuba Ama-80% ee-spikes zokwenyani zivela ngaphakathi kwisakhiwo—ibangelwa zii-air conditioner, iipompo, kunye neefriji ezivulayo nezicimayo. I-220 surge protector elula iyanciphisa ezi surges zangaphakathi kwaye igcina izixhobo zikhuselekile.

Kwimisebenzi yemizi-mveliso, amandla okutsalwa kwamandla ombane anamandla ngakumbi kuba imithwalo inzima. Iimoto, izifudumezi ze-induction, kunye nezixhobo zokuwelda zenza ii-switching transients ezinkulu kakhulu. Ngoko ke ndihlala ndicebisa ukuba i-SPD yemizi-mveliso ngesantya esiphezulu kwiindawo zokusebenzela, amagumbi e-CNC, okanye iifektri ezincinci ezisebenza kwimigca ye-220 V.

Nantsi indlela ekhawulezayo endiyisebenzisa rhoqo xa ndifundisa iingcali ezintsha:

Le theyibhile ilula inceda abathengi ukuba bakhethe uhlobo olufanelekileyo ngokukhawuleza kwaye baphephe ukuchitha imali eninzi okanye ukukhuselwa kancinci.

Ukuqonda uKhuseleko lokuKhuphuka ngesiSpanish kubasebenzisi beHlabathi

Ndisoloko ndiziva ndinoxanduva xa ndinceda abathengi abathetha iSpanish, kuba ingcaciso ecacileyo iqinisekisa ukuba bakhetha ukhuseleko olufanelekileyo lokushushuluza kwiifektri okanye emakhaya.

Ukukhuselwa koxinzelelo ngeSpanish kuchazwa kusetyenziswa amagama anjengelithi “dispositivo de protección contra sobretensiones (SPD)” kunye nelithi “pararrayos,” achaza indlela esi sixhobo esilawula ngayo ii-voltage spikes eziyingozi kwaye sikhusele iinkqubo zombane kwiindawo zokuhlala, zorhwebo, kunye nezoshishino.

Kuba inkampani yam ithumela kwamanye amazwe Isixhobo sokukhusela ukugquma iimveliso eziya eSpain, eMexico, eChile, nakwezinye iimarike ezithetha iSpanish, ndifunde ukuba abathengi abaninzi bayasokola ngomahluko phakathi kwe-“SPD,” “protector contra sobretensiones,” kunye ne-“pararrayos.” Ngoko ke ndihlala ndiwahlulahlula ngolwimi olulula.

NgeSpanish, igama elipheleleyo lobugcisa lithi:
Isixhobo soKhuselo lokuGqibela (i-SPD)
Oku kubhekisa kwisixhobo esifanayo sokukhusela ukugquma esisetyenziswa kwihlabathi liphela.

Kwelinye icala, eli gama intonga yombane idla ngokubhekisa kwisixhobo sokuthintela umbane sangaphandle, kungekhona i-SPD ngaphakathi kwisakhiwo. Abathengi abaninzi baxuba la magama, ngoko ke ndihlala ndicacisa umahluko ukuqinisekisa ukuba bafaka izixhobo ezichanekileyo.

Nantsi itheyibhile elula yesalathiso seelwimi ezimbini endiyabelana ngayo nabaphathi beenkonzo zokuthenga kwihlabathi liphela:

Xa ndichaza ukhuseleko lokushushu ngokusebenzisa ulwimi lwabo, abathengi bayayithemba ngakumbi le nkqubo. Oku kunceda ukuthintela ukungalingani kweenkcukacha, enye yezona ndawo zinzima kubathengi behlabathi.

Kutheni i-ABB Umkhuseli wokunyuka Ithembekile kwiinkqubo zamandla ezimboni

Ndiziva ndiqinisekile xa ndibona i-ABB surge protector kwiphaneli yemizi-mveliso kuba umgangatho wayo wokwakha kunye nemigangatho yovavanyo iyahlangabezana nolindelo lwezityalo zokuvelisa zehlabathi.

Isikhuseli sotyando lwe-ABB sithembekile kuba sinika amandla okuphatha utyando olunamandla, ukunqanyulwa kobushushu okuthembekileyo, iziqinisekiso zehlabathi, kunye nozinzo lwexesha elide oluxhomekeke kubasebenzisi bemizi-mveliso ukukhusela izixhobo ezibuthathaka.

Nanini na xa abaphathi bokuthenga bethelekisa iimpawu ezahlukeneyo ze-SPD zoshishino, ndisoloko ndiphawula ukuba i-ABB ivela rhoqo kuluhlu lwabo olufutshane. Isizathu silula: olu phawu lunedumela elide ngokusasazwa kwamandla, kwaye ii-SPD zalo zilandela imigangatho yovavanyo engqongqo.

Kodwa ndikwachaza nokuba i-ABB ayilo khetho lodwa olufanelekileyo—iimpawu ezifana i-leikexing (inkampani yam) ibonelela ngezixhobo ezisebenza kakuhle ngexabiso elikhuphisanayo, nto leyo ibalulekileyo kwiinkampani ezigxile ekwehliseni i-TCO. Nangona kunjalo, isikhundla se-ABB kwimarike sinceda abathengi baqonde ukuba "umgangatho olungileyo" ubonakala njani.

Nantsi indlela i-ABB edla ngokuthelekisa ngayo nabanye ababoneleli:

Nokuba abathengi bakhetha uphawu lwam, ndisoloko ndibakhuthaza ukuba basebenzise inqanaba lokusebenza le-ABB njengomlinganiselo. Oku kugcina ulindelo lucacile kwaye kunceda ekwakheni ukuthembana kwexesha elide phakathi komthengisi kunye nomthengi.

Xa kufuneka i-High Voltage Surge Protector kwiZixhobo eziNzima

Ndisoloko ndilumka xa ndibona iimoto ezine-voltage ephezulu okanye ii-transformer zisebenza ngaphandle kokukhuselwa okufanelekileyo kokushushu kuba amandla okushushu kula manqanaba anokutshabalalisa izixhobo ngemizuzwana.

Isikhuseli sombane ophezulu siyafuneka xa izixhobo ezinzima zisebenza ngaphezulu kwamanqanaba asezantsi e-voltage aqhelekileyo kwaye zijongene nemingcipheko evela kumbane, ukutshintsha i-transformer, ukuqala kwemoto, kunye nokuphazamiseka kwegridi okugqitha umthamo oqhelekileyo we-SPD.

Xa ndihamba phakathi kwemizi-mveliso yentsimbi, imisebenzi yemigodi, okanye iifektri ezisebenzisa amandla amaninzi, into yokuqala endiyijongayo yindawo engenayo ene-voltage ephezulu. Kula manqanaba—3 kV, 6 kV, 10 kV, okanye ngaphezulu—amandla okushushu ngamandla anamandla kakhulu. I-SPD eqhelekileyo ayinakuyilawula.

Izixhobo ezinzima ezifana neecompressor, iipompo ezinkulu, iilifti, kunye noomatshini bokutyumza zivelisa ii-switching surges zangaphakathi ezibuyela kwinkqubo. Ngaphandle kwe-high-voltage surge arrester, ezi spikes zonakalisa kancinci i-insulation kwaye zinciphise ubomi bezixhobo.

Ndihlala ndinika imithetho emithathu elula yokugqiba ukuba ufuna i-SPD ene-voltage ephezulu:

1. Ukuba usebenzisa iimoto ezingaphezu kwe-100 HP — Ewe

2. Ukuba umbane ubonakala kakhulu — Ewe

3. Ukuba ixesha lokungasebenzi libiza ngaphezu kokhuseleko — ewe ngokupheleleyo

Le mithetho ilula inceda abaphathi bokuthenga ukuba bathethelele isigqibo ngokukhawuleza.

Ukukhetha isixhobo esifanelekileyo sokukhusela i-Surge kwiPaneli yoMbane

Ndisoloko ndiziva ndiqinisekile ngakumbi xa i-SPD ngaphakathi kwiphaneli ihambelana noyilo lwenkqubo, kuba ukhetho olungalunganga lunokuwenza buthathaka uthotho lonke lokhuseleko.

Isixhobo esifanelekileyo sokukhusela i-Surge kwiphaneli yombane sikhethwa ngokwereyithingi ye-voltage ehambelanayo, udidi lwe-SPD, umthamo wamandla okuqhuba i-surge, kunye nendawo yokufakela. Oku kuqinisekisa ukuba iphaneli inokufunxa ii-spikes kwaye ikhusele imithwalo esezantsi ngokukhuselekileyo nangokuthembekileyo.

Xa ndakha okanye ndiphonononga uyilo lwephaneli, ndihlala ndiqala ngezinto ezisisiseko: imeko yegridi, uhlobo lwesixhobo, kunye nembali yeziphene. Ezi zinto zindinceda ukuba ndikhethe udidi lwe-SPD olungcono.

Umzekelo:

• Iklasi yoku-1 kwiinkqubo ezithandwa ngumbane okanye zangaphandle

• Iklasi yesiBini kwiiphaneli zombane ezininzi zemizi-mveliso

• Iklasi yesi-3 kwizixhobo ezibuthathaka ezifana neekhompyutha kunye nee-PLC

Ndikhetha nee-SPD ezineemodyuli ezinokuthi zitshintshwe, kuba zinciphisa ixesha lokulungisa kwaye zinciphise iindleko zexesha elide. Oku kubaluleke kakhulu kubathengi abanjengoJeff, abakhathalele ukuhanjiswa okuqikelelweyo, umgangatho ozinzileyo, kunye ne-TCO ephantsi.

I-SPD ekhethwe kakuhle iguqula iphaneli yombane ibe ngumgca wokhuselo oqinileyo, inciphisa ukusilela kwaye igcine umgca wemveliso usebenza ngaphandle kokuphazamiseka.

Isiphelo

Icebo elithembekileyo lesixhobo sokukhusela ukugqobhoza likhusela izixhobo, linciphisa ixesha lokungasebenzi, kwaye ligcina yonke inkqubo yombane isebenza ngokukhuselekileyo—ngoko ke tyala imali kukhuseleko oluqinileyo lokugqobhoza ngaphambi kokuba kuqhume i-spike elandelayo.
