Indlela Yokufaka Isivikelo Sokukhuphuka Kohlobo 2: Umhlahlandlela Wesinyathelo Ngesinyathelo

Ngivame ukuzizwa ngicindezelekile lapho ukuphakama kwamandla kagesi okungalindelekile kusongela ukulimaza imishini ebalulekile endaweni yami, ngakho-ke ngifunda ukufaka umshini othembekile Idivayisi Evikelayo Yokukhuphukakwaba yinto ebalulekile emsebenzini wami.

Isivikelo sokwanda kohlobo lwesibili sifakiwe kuphaneli enkulu yokusabalalisa kagesi ukuvimba ama-overvoltage esikhashana ngokuqondisa amandla amaningi ngokuphephile ohlelweni lokufaka phansi. Sinciphisa ukwehluleka kwemishini, sivimbele isikhathi sokungasebenzi, futhi sivikele imithwalo yezindlu neyezimboni. Ukufakwa okufanele kudinga amathuluzi afanele, imikhuba yokuxhuma izintambo ephephile, kanye nokuhlolwa kwangemva kokufakwa ukuqinisekisa ukuvikelwa okugcwele.

Manje ake ngikuhambise ngesinyathelo ngasinye ukuze ukwazi ukuqedela ukufakwa okuphephile nokuqinisekile.

Yimaphi Amathuluzi Adingekayo Uhlobo 2 lwe-SPD Ukufakwa?

Bengivame ukwethuka njalo lapho ngivula iphaneli yokusabalalisa ngoba ngangesaba ukuthi ngeke ngibe namathuluzi afanele okufakwa kahle kwe- Idivayisi Evikelayo Yokukhuphuka.

Udinga amathuluzi okushisa afudumele, i-PPE efanele, imishini yokuvala i-tagout, kanye namathuluzi okulinganisa kagesi ukuze ufake i-Type 2 SPD ngokuphephile. Lawa mathuluzi aqinisekisa ukuqedwa kwentambo okuphephile, ukuqinisa i-terminal ngokuqinile, ukusetshenziswa kwe-torque efanele, kanye nokuqinisekiswa kwe-voltage ngaphambi nangemva kokuxhuma izintambo.

Uma ngifaka i-Type 2 SPD, ngihlala ngigcina isethi yamathuluzi ephelele nehlelekile ukuze ngikwazi ukusebenza ngokushesha futhi nginciphise amaphutha. Ngisebenzisa izikulufo ezivikelayo ngoba zinginika ukuzethemba lapho ngisebenza ngaphakathi kwezimo ezinamandla, yize ngihlala ngisusa amandla ngokuphelele ephaneli ngaphambi kokuthinta noma yini. Ngiphinde ngilungiselele amagilavu, izibuko zokuzivikela, kanye namadivayisi okukhiya ngaphandle ngoba ukuphepha kuhlala kuyinto eza kuqala kimi.

Ukuze sikusize uhlale uhlelekile, nansi uhlu lokuhlola amathuluzi engilulandelayo mathupha:

Ithebula 1: Amathuluzi Abalulekile Okufakwa Kwe-SPD Yohlobo 2

Noma nini lapho ngilungiselela la mathuluzi, ngiqeda ukufaka ngokushesha futhi nginamaphutha ambalwa okuxhuma. Ngiphinde ngihlole i-screwdriver yami ye-torque ngoba ama-terminals akhululekile angenye yezimbangela eziyinhloko zokwehluleka kwe-SPD. Ukuba nakho konke kulungile kungisiza ukuba ngilondoloze ukuhamba komsebenzi kobungcweti, ikakhulukazi lapho ngisebenza namakhasimende ezimboni alindele ukwenziwa okuthembekile njalo.

Ungayixhuma Kanjani Ngokuphepha Intambo Uhlobo 2 Isivikelo Sokukhuphuka?

Ngikhumbula ngizizwa nginovalo okokuqala lapho ngixhuma i-Type 2 SPD ngoba ngangikhathazekile ngokuthi uxhumano olulodwa olungalungile lungase lonakalise imishini esikhundleni sokuyivikela. Kodwa ngemva kokufunda indlela ehlelekile, ukuxhuma izintambo kwaba lula.

Uxhuma i-Type 2 surge protector ngokuxhuma ama-line terminals ayo ku-breaker, i-neutral terminal ku-neutral bar, kanye ne-ground terminal ku-grounding bar. Zonke izintambo kumele zibe zimfushane, ziqonde, futhi ziqiniswe ezingeni elifanele le-torque ukuze kuncishiswe i-impedance futhi kuthuthukiswe ukusebenza kwe-surge.

Uma ngixhuma i-Type 2 SPD, into yokuqala engiyenzayo ukuqinisekisa ukuthi ugesi unqanyuliwe ngokuphelele. Ngihlola yonke i-terminal ngesihloli se-voltage ngoba ngisho nochwepheshe bakagesi abanolwazi bangenza amaphutha uma becabanga ukuthi iphaneli ayinamandla. Ngemva kokuqinisekisa ukuphepha, ngifaka idivayisi eduze kwe-breaker ukuze ngigcine ubude bekhebula bufushane. Izintambo ezimfushane zinikeza i-SPD isikhathi sokuphendula esisheshayo kanye nokusabalala okungcono kokugeleza.

Okulandelayo, ngilandela lezi zinyathelo ngokucophelela:

1.Xhuma i-L1, i-L2, i-L3 (yesigaba esi-3) noma i-L (yesigaba esisodwa)kumuntu ozinikele ekuphuleni.

2.Xhuma i-terminal ye-Nkubha engathathi hlangothi uma uhlelo luyidinga.

3.Xhuma i-terminal ye-PE/Gngqo kubha yokumisa.

4.Hlola amanani e-torquekwetheminali ngayinye ngokusho kweshidi ledatha le-SPD.

5.Lebula i-SPDukuhambisana nezindinganiso zezikhungo kanye nokuhlolwa kwamabhuku.

Ngemva kokufaka izintambo, ngihlola ngokubonakalayo ukuqinisekisa ukuthi azikho izintambo ezihlanganisiwe noma ukuxhumana okuxekethile. Ezindaweni zezimboni, lesi sinyathelo sibalulekile ngoba ukudlidliza ezindaweni ezinkulu kungabangela ukuthi ama-terminal axekethile ngokuhamba kwesikhathi. Izintambo ezimfushane nezihlanzekile nazo zisiza abahloli kanye nochwepheshe ukuqonda ukufakwa ngokushesha.

Yimaphi Amaphutha Okufanele Uwagweme Lapho Ufaka Ama-SPD Ohlobo 2?

Ngenze amaphutha amaningi ekuqaleni komsebenzi wami ngoba ngangingaqondi ngokugcwele ukuthi i-SPD ibucayi kangakanani kwikhwalithi yokufaka. Ngokuhamba kwesikhathi, ngafunda ukuthi yimaphi amaphutha anganciphisa kakhulu izinga lokuvikelwa kwedivayisi.

Amaphutha avamile afaka phakathi ukusebenzisa izintambo ezinde, ukuxhuma izintambo ngobukhulu obungalungile be-breaker, ukunganaki imininingwane ye-torque, nokufaka i-SPD kude kakhulu ne-busbar eyinhloko. Lezi zinkinga zandisa i-impedance futhi zinciphisa ikhono le-SPD lokumunca noma ukuqondisa kabusha amandla okukhuphuka.

Uma ngibuyekeza amaphrojekthi avela kochwepheshe abasha, ngivame ukuthola amaphutha afanayo okufaka ephindaphindwa. Ukufakwa kwezintambo ezinde kuyinkinga evame kakhulu ngoba abafaki abaningi abaqondi ukuthi ukuvimba kwekhebula kuthinta ngqo ukusebenza kwe-SPD. Ukwanda komoya kuthatha amasekhondi amancane, ngakho-ke ngisho namaphutha amancane okufakwa kwezintambo angalibazisa ukuqondisa kabusha amandla.

Ngihlala ngifundisa iqembu lami imithetho elandelayo:

Ithebula 2: Amaphutha Okufakwa Kwe-SPD Yohlobo 2 Oluvamile

Ngokugwema la maphutha, ngiletha imiphumela eqhubekayo kumakhasimende ezimboni athembele ekusebenzeni kukagesi okuzinzile. Amafektri amaningi asebenzisa imishini ebiza kakhulu, ngakho ukufakwa kwe-SPD okuhlulekile kungaholela esikhathini esibi kakhulu sokungasebenzi. Ukufakwa kwezintambo kanye nokufakwa kwesisekelo okulungile kugcina uhlelo luphephile futhi lubikezelwe, okuyilokho kanye abaphathi bokuthenga abanjengoJeff Weaver abakulindele lapho behlola abahlinzeki.

Uyihlola Kanjani i-Type 2 SPD Ngemva Kokufakwa?

Ngihlala ngizizwa ngikhululekile lapho inqubo yokuhlola ye-SPD iqinisekisa ukuthi konke kusebenza kahle, ngoba ukuhlola kuwubufakazi bokugcina bokuthi ukufakwa kuphephile futhi kulungele ukusebenza isikhathi eside.

Uhlola i-Type 2 SPD ngokuqinisekisa ubukhona be-voltage, ukuhlola amafasitela ezinkomba, ukuqinisekisa ukuqhubeka kokumisa phansi, nokuhlola ubuqotho be-breaker. Amanye ama-SPD ezimboni afaka ama-terminal okubonisana akude okumele ahlolwe ukuqinisekisa ukuthi uxhumano lwe-alamu lusebenza kahle.

Ukuhlola kulula uma kwenziwa kahle, futhi ngilandela inqubo yokuhlola eqhubekayo kuyo yonke iphrojekthi:

1.Hlola iwindi lesimo se-SPD(oluhlaza = okuhle, obomvu = ukufaka esikhundleni).

2.Sebenzisa i-multimeterukuqinisekisa i-voltage efanele ku-breaker.

3.Kala ukuqhubeka kokumisa phansiukuqinisekisa ukungasebenzi kahle kwe-impedance.

4.Hlola ama-alamu akudeuma kufakiwe.

5.Qinisekisa usayizi we-breaker kanye nezimo zokushisangemva kokuvula.

Ukuze inqubo yokuhlola icace kakhudlwana, nansi inqubo engiyilandelayo:

Ithebula 3: Uhlu Lokuhlola Lokuhlolwa kwe-SPD Yohlobo 2

Uma zonke izivivinyo ziphumelela, ngimaka iphaneli bese ngibhala phansi ukufakwa ngoba lokhu kusiza amaqembu okulungisa kanye nabahloli esikhathini esizayo. Imibhalo emihle yakha ukwethembana nabaphathi bokuthenga futhi iqinisekisa ukubambisana kwesikhathi eside, okubalulekile emisebenzini yezimboni encike ekuvikelweni okuzinzile kokukhuphuka kwezimboni kanye nemishini esindayo.

Isiphetho

Faka eyakho Idivayisi Evikelayo Yokukhuphukangamathuluzi afanele, izintambo eziphephile, kanye nokuhlolwa okufanele ukuqinisekisa ukuvikelwa okuthembekile kwesikhathi eside.

Imibuzo Evame Ukubuzwa

1. Iyini idivayisi yokuvikela yohlobo lwesibili?

I-Type 2 SPD ifakiwe kuphaneli kagesi eyinhloko ukuvikela imishini ekushiseni kwamandla kagesi okudlulayo okubangelwa ukukhuphuka kwamandla kagesi noma umbani ongaqondile.

2. Ingabe ngidinga i-breaker ye-Type 2 SPD?

Yebo. I-breaker ezinikele iqinisekisa ukunqanyulwa okuphephile ngesikhathi sokulayisha ngokweqile futhi ivikela i-SPD ezimweni zamaphutha.

3. I-SPD yohlobo lwesibili ihlala isikhathi esingakanani?

Ama-SPD amaningi ahlala iminyaka eminingana, kuye ngokuthi imvamisa yokwanda kwegesi ingakanani, ikhwalithi yokufaka, isisekelo, kanye nezimo zemvelo.

4. Ngingafaka i-Type 2 SPD ngaphandle?

Cha. Ama-SPD ohlobo lwesibili aklanyelwe ukufakwa ngaphakathi ngaphandle kokuthi idivayisi ilinganiswe ukusetshenziswa ngaphandle.

5. Kungani ukusekela kubalulekile kuma-SPD?

Ukubeka phansi kunikeza indlela ephansi kakhulu yokuvimbela amandla okukhuphuka, okuqinisekisa ukuqondiswa kabusha okusheshayo nokuphephile kude nemishini.
