Ukusebenza kweCandelo lokuKhuselwa kweNkcukacha (SPD)

Ngokwesiqhelo, abantu bahlawula ingqalelo enkulu ekusebenzeni kwesixhobo sokukhusela (SPD) njengamandla aso okukhula. Ukunyuka kwamandla kubaluleke kakhulu. Kukho izixhobo ezininzi zokukhusela (SPDs) kwiimarike azikwazi ukuhlangabezana namandla okuvakalisa. Nanku umfanekiso kunye nevidiyo ye-SPD eqhume kuvavanyo lwangoku (Imax 40kA):

Isixhobo esiphezulu sokukhusela isixhobo sichithwe

Ukukhuselwa kweNkqubo yokuKhuselwa kweziKhuseleko (SPD)

Nangona kunjalo imbalwa ingqalelo ehlawulwa kukhuseleko lwezixhobo zokukhusela. Nangona kunjalo, i-SPD eyilwe kakubi inokuba yingozi kakhulu kwaye sesinye sezizathu eziphambili zomngcipheko womlilo. Apha ngezantsi kukho imifanekiso etshisiweyo ye-SPD:

UL Warns of Potentially Hazardous Surge Protectors

I-NORTHBROOK, i-Ill. Julayi 29, 2016 - Oku kulandelayo isaziso esivela ku-UL ukuba abakhuseli abakhuselekileyo bangaphantsi bangabangela ingozi yomlilo. Imveliso ayihambisani neMigangatho yoKhuseleko ye-UL kwaye ayigunyazisiweyo ukuba ithwale i-UL Mark kwi-United States okanye eCanada.

I-ABC News Report - Isixwayiso kubaphathi bezindlu: Isixhobo sokukhusela ekhaya singabangela umlilo

CARY, NC (WTVD) -Isebe laseCary Fire lilumkisa abaninimzi kulandela umlilo wesihlanu oqhagamshelene nomkhuseli otyholayo kule dolophu kule minyaka mine idlulileyo.
“Siqale ngohlobo lokuzibona ezi ndidi zomlilo zenzekileyo, ngakumbi lowo ubenomonakalo omkhulu ekhayeni. Umlilo ohambe unyuka ngevinyl yasekhaya, emva koko ungene kwigumbi eliphezulu, kwaye ekugqibeleni ungene eluphahleni, utshilo uCary FD Capt uScott Benninghoff.

I-SPD / MOV yiNkohlakalo yokuPhathwa kwexeshana (TOV)

I-SPD ayilungiswanga kakuhle okanye ingasetyenziswa ngokungafanelekileyo kwaye ii-MOV ezingakhuselekanga zingena kwi-thermal away escape, ezibangelwa kwisigqeba esifutshane, ukufudumala, ukutshaya kunye nomngcipheko womlilo ngenxa yoku:

  • Ukuphela kobomi
  • Ukuxhatshazwa okungavamile / ukuqhutyelwa kwexesha elifutshane (TOV)
  • Ukunyuka ngamandla angalindelekanga

I-MOV okanye i-SPD ngabakhuseli beNtshukumo yokuThuthukiswa kwexesha elifutshane (okanye ukunyuka) kodwa amaxhoba oPhuculo lwexeshana.

I-MOV etshisiwe phantsi koGqithiso lweThutyana

Ukukhuselwa kweSisombululo soKhuseleko lweSixhobo-iTPAE yeTekhnoloji

I-Prosurge iphuhlise itekhnoloji ye-TPAE (UkuCinywa kweArc ekhuselweyo ngokwasemoyeni) ukusombulula ingxaki yezokhuseleko ye-SPD kwaye sinobuchwephesha obunelungelo lobunikazi e-USA, Germany, Korea nase China.

Ngokusekwe kwitekhnoloji ye-TPAE, siphuhlise icandelo lethu eliphambili le-SPD- iSMTMOV kunye nePTMOV.

SMTMOV

I-TPMOV - I-MOV yeWormally Protected

PTMOV

Uyayibona indlela imveliso yethu ehlala ikhuselekile ngayo kugqithiso lwevoltage eqhubekayo ngelixa imveliso yokhuphiswano lwethu itshisiwe.

Kwi-415Vac ukuqhuma kwexeshana, i-SMTMOV yethu kunye neTAPE iteknoloji iyazicima le imeko engavumelekanga ize ihlale ikhuselekile

Kwi-415Vac ukuqhutyelwa kwexesha elifutshane, inxalenye ye-SPD ngaphandle kweteknoloji ye-TPAE yatshiswa kakubi.

Kuvavanyo olungezantsi, ii-SPDs ezimbini zivavanywa phantsi kwe-TOV (i-overvoltage yexeshana). Jonga ukuba iziphumo zahluke njani kwi-SPD ngokhuseleko lwe-TPAE kunye ne-SPD ngaphandle kokhuseleko lwe-TPAE:

Ngeprosurge iteknoloji ye-TPAE enegunya lobunikazi, i-SPD ihlulekile-iphephile kwaye ikhuselekile.

Ngaphandle kwesixhobo sokucima i-arc, i-SPD ibangela umsi nomlilo, okuya kuba yingozi kwesekethe.
