Kungani Izinsizakalo Zokuvikela Ukuqhuma Zibalulekile Ezikhungweni Zanamuhla

Ngivame ukuzizwa ngicindezelekile ngokwazi ukuthi ukuqhuma okukodwa okungazelelwe kungamisa kanjani ukukhiqiza ngokushesha, ngakho-ke ngithembele ku- Idivayisi Evikelayo Yokukhuphuka hlela ukuhlala uphephile.

Izinsizakalo zokuvikela ukukhuphuka kwamandla zibalulekile ezakhiweni zesimanje ngoba zivikela imishini ekukhuphukeni kwamandla kagesi, ziqinise ikhwalithi yamandla, futhi zinciphisa isikhathi sokungasebenzi. Lezi zinsizakalo zisebenzisa ama-SPD ahlanganisiwe, izinhlelo zokumisa, kanye nezakhiwo zokuvikela ukuvimbela umonakalo ovela embaneni, ukushintshashintsha kwezinguquko, kanye nokuphazamiseka kwegridi.

Uma ngihamba kunoma iyiphi indawo yokukhiqiza, ngihlala ngibona iqiniso elilodwa: ukuzinza kwamandla kunquma umkhiqizo. Yingakho izinsizakalo zokuvikela ukukhuphuka kwegesi sezibalulekile ezinkampanini ezithembele ekusebenzeni okuqhubekayo. Manje, ake ngichaze ukuthi ingxenye ngayinye isebenza kanjani nokuthi kungani ibalulekile.

Indlela Ukuvikelwa Kokukhuphuka Kombani Okuvikela Ngayo Izinhlelo Zezimboni

Ngivame ukukhathazeka ngokuthi umbani uthinta kanjani umkhiqizo ngoba ngibone ukushaywa kwezibhamu konakalisa wonke amakhabethe okulawula, ngakho ngihlala ngithemba i-eqinile Idivayisi Evikelayo Yokukhuphuka ukucushwa.

Ukuvikelwa kokukhanya kombani ivikela izinhlelo zezimboni ngokuqondisa kabusha imisinga yombani enamandla aphezulu isuke kumasekethe, yehlise ama-voltage aphezulu ayingozi, futhi ivimbele ukuwohloka kokushisa. Isebenza ngama-SPD ahlelekile, ukusekelwa okufanele, kanye nokubopha okuphumelelayo okuvimba amandla ayingozi ukuthi angafinyeleli emishinini ebucayi.

Uma ngicabanga ngokuvikela indawo ekukhanyeni kombani, ngihlala ngiyiqhathanisa nokwakha isihlangu esizungeze izimpahla zakho ezibaluleke kakhulu. Amandla ombani ayashesha, anamandla, futhi awalindeleki. Angena ngemigqa ephezulu, izakhiwo zensimbi, noma ngisho nemizila yomhlaba eseduze. Ngenxa yalokho, angikaze ngithembele ku-SPD eyodwa. Kunalokho, ngisebenzisa isakhiwo esinezingqimba esivikela uhlelo kuzo zonke izigaba.

Nasi ithebula elibonisa izindawo ezahlukene zefektri kanye nezinga lokuvikelwa elinconywayo:

Ngihlala ngitshela abaphathi bokuthengwa kwempahla ukuthi umbani awuthetheleli amaphutha. Uma kukhethwa izinga le-SPD elingalungile, ukukhuphuka kuzomane kudlule ukuvikelwa bese kuhlasela idivayisi elandelayo engavikelekile. Yingakho ukukhetha i-SPD yombani efanele kubalulekile ezinhlelweni zezimboni ezibiza kakhulu.

Ukuqonda Ububanzi be-SPD bezidingo ezahlukene zikagesi

Ngivame ukuzizwa ngingaqiniseki uma ngibheka amakilasi ahlukene e-SPD ngoba ukukhetha isilinganiso esingalungile kungabangela isikhathi sokuphumula esibizayo, ngakho-ke ngihlala ngithembele kudatha ecacile ngaphambi kokwenza izinqumo.

Ububanzi be-SPD buyahlukahluka ngokuya ngomthamo wokwanda, isilinganiso se-voltage, isivinini sokuphendula, kanye nendawo yokufaka. Isigaba ngasinye se-SPD sivikela izingxenye ezithile zesakhiwo emazingeni ahlukene okwanda, okuvumela amafektri ukuthi agcine ukusebenza okuzinzile ngisho nangesikhathi sokuphazamiseka okukhulu.

Ngesikhathi ngiqala ukuphatha amaphrojekthi okuvikela ukukhuphuka, ngafunda ngokushesha ukuthi ama-SPD awakwazi ukushintshaniswa. I-SPD yohlobo 1 imelana nokukhanya kombani emnyango wesakhiwo. I-SPD yohlobo 2 ivikela amabhodi okusabalalisa ekushintsheni ukukhuphuka. I-SPD yohlobo 3 ibekwa eduze kwe-elekthronikhi ebucayi ukuze kumiswe ukukhuphuka okuncane okusele. Lapho la madivayisi esebenza ndawonye, ​​​​isikhungo sonke siba namandla kakhulu.

Ngezansi kunethebula lokuqhathanisa elicacile engivame ukulihlanganyela nabathengi:

Ngokwalokho engikubonile, ngihlala ngincoma ukukhetha ama-SPD anezilinganiso zamanje zokukhuphuka okuphezulu kunezindinganiso zendawo eziphansi. Izimboni eziningi zisebenzisa ama-motor asindayo, imigqa yokuzenzakalela, kanye nama-transformer akhiqiza ukukhuphuka okuvamile kokushintsha. Lezi zenzakalo ezincane kodwa eziphindaphindwayo zingenza imishini ibe buthaka ngokuhamba kwesikhathi. I-SPD enamandla iqinisekisa ukuzinza kwesikhathi eside kanye nokusebenza okubikezelwayo, okuyinto abathengi abanjengoJeff abayazisa kakhulu.

Uma Kufanele Usebenzise Isivikelo Sokukhuphuka Ukuze Uvimbele Ukulimala Kwemishini

Ngivame ukuzizwa ngingakhululekile uma ngibona imishini ebizayo isebenza ngaphandle kokuvikelwa kokushiswa, ngakho-ke ngihlala ngicindezela ukufakwa kwe-SPD isikhathi eside ngaphambi kokuba kwenzeke ukwehluleka kokuqala.

Kufanele usebenzise isivikelo sokukhuphuka uma imishini yakho ibhekene nombani, amagridi kagesi angazinzile, ukusebenza kokushintsha, ukusebenza kwekhebula isikhathi eside, noma izilawuli ze-elekthronikhi ezibucayi. Ama-SPD avimbela ukwehluleka kwemishini, anciphisa isikhathi sokungasebenzi, futhi andise isikhathi sokuphila komshini.

Uma ngibheka indlela amafektri anamuhla asebenza ngayo, ngihlala ngithola iphethini efanayo: imishini iba ngcono kakhulu, ibucayi kakhulu, futhi ibiza kakhulu. Kodwa-ke, indawo yamandla iba engazinzile kakhulu ngenxa yemisebenzi yokushintsha njalo, ama-harmonics, kanye nokuziphatha kwegridi okungalindelekile. Ngaphandle kwe-SPD, ngisho nokuqhuma okuncane kungalimaza idrayivu, i-PLC, noma ikhompyutha yezimboni.

Ngezansi ithebula elifingqa imithombo evamile yokwanda kanye nohlobo lwe-SPD olufanele kakhulu:

Ngokwalokho engikubonile, izindleko zesikhathi sokungasebenzi zihlala zidlula izindleko zokufaka i-SPD. Abaphathi bokuthengwa kwempahla abagxile ezindlekweni eziphelele zobunikazi baqonda ngokushesha ukuthi ukuvikelwa kokukhuphuka kwentengo kungenye yezindlela ezilula zokunciphisa ingozi yokusebenza yesikhathi eside.

Indlela Amadivayisi Okuvikela Ukwanda (ama-SPD) Athuthukisa Ngayo Ukuthembeka Kwamandla

Ngivame ukukhungatheka lapho ngibona imigqa yokukhiqiza ima ngenxa yamandla angazinzile, ngakho-ke ngihlala ngithembele kunethiwekhi ye-Surge Protective Device ehlelekile ukuze ngigcine ukusebenza kuzinzile.

Ama-SPD athuthukisa ukuthembeka kwamandla ngokuzinzisa i-voltage, ukumunca ama-spikes esikhashana, ukunciphisa ukucindezeleka kumasekethe, nokuvimbela ukuvalwa okungazelelwe. Lokhu kusiza amafektri ukuthi alondoloze ukukhiqizwa okuqhubekayo kanye nokunciphisa isikhathi sokungasebenzi okubangelwa ukuphazamiseka kwamandla okungalindelekile.

Into eyodwa engihlala ngiyiqaphela ukuthi ngisho nokuphakama kwamandla kagesi amancane kungaphazamisa kanjani izinhlelo zokwenza izinto ngokuzenzakalela. Ama-PLC aqina, ashayela aphazamiseke, izinzwa azifundi kahle, futhi ama-loop okulawula ayaphuka. Lezi zenzakalo zibukeka zincane, kodwa ziqongelela ekulahlekelweni okukhulu kokukhiqiza. Njengoba ama-SPD ebekwe ezindaweni ezibalulekile—ama-MCC, amabhodi okusabalalisa, amakhabethe okulawula—lonke uhlelo luba luzinzile kakhulu.

Nasi ukuqhathanisa okulula okubonisa umehluko ngaphambi nangemva kokufakwa kwe-SPD:

Kubathengi abanjengoJeff abakhathalela ukulethwa okubikezelwayo, izinqubo ezizinzile, kanye nekhwalithi eqhubekayo, ama-SPD adlala indima enkulu ekunciphiseni ubungozi bokusebenza.

Kungani Isivikelo Sokukhuphuka Kwangaphandle Sibalulekile Ezinhlelweni Zangaphandle

Ngivame ukukhathazeka uma ngibona iziteshi zangaphandle zingavikelekile ngoba zibhekene nokuchayeka okuphezulu kakhulu, ngakho-ke ngihlala ngifaka ama-SPD angaphandle kuqala.

Isivikelo sangaphandle sokukhuphuka sibalulekile ngoba imishini yangaphandle ivezwa umbani, ukugeleza kwezintambo ezinde, ukuphakama okungenzeka komhlaba, kanye nesimo sezulu esibi kakhulu. Ama-SPD angaphandle avimba lokhu kuphakama kwangaphandle ngaphambi kokuba afinyelele ezinhlelweni zangaphakathi.

Uma ngisebenza ngemishini yangaphandle—izigxobo ze-CCTV, amasango, amayunithi e-HVAC, ama-solar arrays—ngihlala ngiwaphatha njengezindawo ezisengozini kakhulu kuso sonke isikhungo. I-surge ingadlula ngekhebula lesignali elula futhi yonakalise ibhodi lokulawula eliqhele ngamamitha angamakhulu. Yingakho ngihlala ngikhetha izilinganiso zamandla aphezulu kanye nezindlu ezimelana nesimo sezulu zokufakwa kwangaphandle.

Njengoba kufakwe ama-SPD angaphandle, sonke isakhiwo siba namandla kakhulu ezimweni zemvelo ezingalindelekile.

Isiphetho

Uqinile ukuvikelwa kokuqhuma kuyindlela elula yokunciphisa isikhathi sokungasebenzi, ukuvikela imishini, nokugcina amafektri esimanje esebenza kahle ngokusebenza okubikezelwayo. Khetha njalo izinga lezimboni Idivayisi Evikelayo Yokukhuphuka izixazululo zokuvikela uhlelo lwakho lonke.
