Kutheni Izixhobo Zakho Zifuna "iVoltage Bodyguard"?

Khawucinge ngale nto: Ngobusuku obunesaqhwithi obunemibane edlula esibhakabhakeni, izixhobo zakho zokuchaneka ezixabisa amakhulu amawaka ngequbuliso "ziya kubetha." Lo asingomboniso wefilimu eyoyikisayo kodwa liphupha elibi kakhulu eliye lajongana neefektri ezininzi kunye namakhaya. Isixhobo sokukhusela i-surge (SPD) "siqhawe" kweli bali—esikwaziyo ukukhawulezisa ii-voltage spikes eziyingozi kwisiqingatha sesibini somzuzwana. Kodwa nantsi into ebambekayo: abantu abaninzi bazisa lo "mlindi" ekhaya bengazi ukuba bayisebenzise njani ngokufanelekileyo.

Namhlanje, masithethe ngalo mlindi wokhuseleko lombane obonakala ulula kodwa untsonkothile kakhulu.

Inxalenye 1: Yazi "unogada wakho we-elektroniki"

1.1 Luhlobo luni "lweteknoloji emnyama" oluyi-SPD?

Ukuthetha inyani, umgaqo wokukhusela i-surge awunzima. Ufana "ne-smart switch", ehlala ithule ngamaxesha aqhelekileyo. Nje ukuba ibone i-voltage engaqhelekanga (njengamashumi amawaka ee-volts ze-voltage ephezulu ngexesha lombane), inokuvula ucango ikhuphe amanzi" kwimizuzwana emincinci, ize iqhube umsinga oyingozi emhlabeni. Isantya esingakanani esi santya sokusabela? Sikhawuleza kangangezigidi kunokuba uqhwanyaza!

1.2 Ukwahlula "izitho zangaphakathi" ze-SPD

Ii-SPD eziqhelekileyo kwimarike zixhomekeke "kwizakhono ezikhethekileyo" ezintathu ukuze zisebenze:

I-varistor ye-oxide yesinyithi (MOV): ifunxa i-overvoltage njengesiponji ifunxa amanzi

Umbhobho wokukhupha igesi (GDT): iqhuba imisinga emikhulu ngokuyi-ionizing gas

I-diode yokunciphisa isantya (ii-TVS): igxile ekujongeni ezo pulses "zimbi" ezingenamandla aneleyo

Okubangel’ umdla kukuba, iintlobo ezahlukeneyo ze-SPD zinamandla azo. Njengokuba ukukhetha umlindi kungajongi nje kuphela izihlunu, ukukhetha i-SPD kukwaxhomekeke kwimeko ethile - iimfuno zeworkshop yefektri kunye nethiyetha yasekhaya zahlukile kakhulu.

Icandelo lesi-2: Kukufundisa indlela yokufaka i-SPD inyathelo ngenyathelo

2.1 Isikhokelo sokuphepha iingxaki ekuthengeni

Kunyaka ophelileyo, umthengi wandikhalazela esithi i-SPD ayithengileyo ayisebenzi. Emva kokubuza, ndafumanisa ukuba ufake imodeli ye-20kA yokusetyenziswa ekhaya kwisikhululo seenqwelo-moya kwindawo enentaba edla ngokubethwa ngumbane! Oku kufana nokusebenzisa isambrela ukuvimba isichotho. Bekuya kuba yinto engaqhelekanga ukuba ayiphukanga.

Khumbula la manani abalulekileyo xa uthenga:

• Ixabiso leVolthi: kufuneka ihambelane! Ukufaka i-380V SPD kwinkqubo ye-220V kufana nokungayifaki

• Umgangatho wohambo: I-40kA iyacetyiswa kwiindawo ezikunxweme olunemibane exhaphakileyo

• Indlela yokukhusela: Uhlobo "1+1" lusetyenziswa kwizixhobo zasekhaya eziqhelekileyo, kwaye uhlobo "3+1" lulungele izixhobo ezichanekileyo

2.2 "Isifundo segazi neenyembezi" kwindawo yokufakela

Kwinyanga ephelileyo, ndiye kwiziko ledatha ukuze ndilungise izinto, ndaza ndafumanisa ukuba i-SPD yabo ifakwe kwiimitha ezi-3 ukusuka kumgca oyintloko! Oku kufana nokutshixa isicima-mlilo kwigumbi elilandelayo. Ukuba kukho umlilo wokwenene, akukho xesha lokuwufumana.

Indlela echanekileyo yokufaka:

• Cima umbane! Cima umbane! Cima umbane! (Izinto ezibalulekileyo mazithethwe kathathu)

• Khumbula ulandelelwano lweentambo: qhagamshela ucingo lomhlaba kuqala, uze uqhagamshele ucingo olungathathi cala, uze ekugqibeleni ucingo oluphilayo

• Zama ukunciphisa ubude bentambo yoqhagamshelo (isiphumo sokukhusela siya kuncitshiswa ngesiqingatha ukuba sidlula iimitha eziyi-0.5)

• Ungalibali ukwenza "uvavanyo lomzimba": sebenzisa i-megohmmeter ukulinganisa ukumelana komhlaba

Nantsi icebo elincinci: beka inqaku elinamathelayo ecaleni kwe-SPD uze ubhale umhla wokufakwa kwayo. Le nto ifana nephedi yebhuleki yemoto, kufuneka itshintshwe emva kwexesha elide isetyenziswa.

Inxalenye 3: Iinkcukacha zolondolozo azinakwa ngabantu abangama-90%

3.1 "Iimpawu zokufa" ze-SPD

• I-SPD ayikwazi ukuthetha, kodwa iya kukuxelela ukuba "ndiyafa" ngezi ndlela:

• Iqokobhe lijika libe tyheli kwaye liguquguquke (njengethoyi yeplastiki endala). Isibane sesalathisi siqala "ukufa" (ngokucacileyo sisebenza kodwa asivuliwe) Esi sixhobo sihlala sineempawu "zeziporho" (ukuqalisa kwakhona okungachazwanga okanye ukuphahlazeka)

• Kucetyiswa ukuba wenze uhlolo olulula rhoqo ngekota: chukumisa ubushushu beqokobhe ngesandla sakho (ukuba kushushu, kukho ingxaki), kwaye ujonge isalathisi sefestile (eluhlaza kuthetha ukuba iphilile, ebomvu kuthetha ukuba kufuneka itshintshwe).

3.2 "Iimpazamo eziphantsi" esazenzayo ngaloo minyaka

• Umboniso wempazamo 1: Ukuphatha i-SPD njengomhombiso "owodwa kwaye uphelele" (enyanisweni, yinto enokutyiwa)

• Umboniso wempazamo 2: Ukudibanisa ucingo lokumisa umhlaba kwisakhelo sesinyithi ngokungacwangciswanga (kufuneka i-electrode yokumisa umhlaba ezinikeleyo)

• Umboniso wempazamo 3: Ukuxuba ii-SPD zeempawu ezahlukeneyo (njengokuthatha amayeza aseTshayina naseNtshona ngokungacwangciswanga)

Eyona nto ingaqhelekanga kukuba ndibone umntu esebenzisa i-SPD njengesixhobo sombane, esizele ziikettle zombane kunye nee-oven ze-microwave...

Icandelo 4: Imibuzo neempendulo ezivela kumlo wokwenyani

Q: Ungaqiniseka emva kokufaka i-SPD?

A: Njengokuba unxibe ibhanti yesihlalo, awunakuyibetha ngabom imoto. I-SPD+lightning arrester+UPS yiphakheji epheleleyo.

Q: Ungagweba njani ukuba i-SPD yonakele okanye izixhobo zinesiphene?

A: Icebo elilula: emva kokususa i-SPD, izixhobo zibuyela kwisiqhelo, emva koko yingxaki ye-SPD.

Q: Ixesha elingakanani ixesha lenkonzo ye-SPD?

A: Oku kuxhomekeke kwinani "lee-beats". Umzekelo, umthengi eGuangdong wafumana ii-lightning beat ezili-12 ngosuku olunye, kwaye i-SPD yakhe yathatha umhlala-phantsi kwiinyanga ezintathu.

Ukuqukumbela: Ingcinga "yokuthenga i-inshurensi" kwiinkqubo zombane

Ndibone abantu abaninzi bezimisele ukuchitha imali eninzi kwizixhobo, kodwa banomdla kakhulu ekukhuseleni. Enyanisweni, i-SPD ifana "ne-inshurensi yezonyango" yenkqubo yombane. Usenokungaziva ukuba ikhona ngamaxesha aqhelekileyo, kodwa inokusindisa ubomi bakho ngamaxesha anzima.

Okokugqibela, ndingathanda ukuthi kuye wonke umntu: ukhuseleko oluhle lokushushuluza alubizi kakhulu, kodwa lolona lufanelekileyo. Ngexesha elizayo xa uthenga, ungabuza umthengisi ukuba loluphi uvavanyo olusebenzayo oluye lwahlangabezana nalo olu hlobo. Kaloku, akukho mntu unesibindi sokuba "nomlindi" othetha ngalo ephepheni kuphela.

Amanqaku oBugcisa:

• Idatha elinganisiweyo ibonisa ukuba ii-SPD ezifakwe kakuhle zinokunciphisa umonakalo wombane nge-82%

• Ngokwe-IEC 61643, ixesha lokuphendula le-SPD esemgangathweni ophezulu kufuneka libe yi-≤25ns

• Kwiindawo ezineendudumo ezinkulu, kucetyiswa ukuba kutshintshwe iindawo eziphambili ze-SPD rhoqo emva kweminyaka emi-3.
