Ukusebenza kweDivaysi Yokuvikelwa Kwesisindo (SPD)

Imvamisa, abantu banaka kakhulu ekusebenzeni kwedivayisi yokuvikela ukuqhuma (i-SPD) njengomthamo wayo wokuqhuma. Amandla wokwanda abaluleke kakhulu impela. Kunamadivayisi amaningi wokuvikelwa kokuqhuma (ama-SPD) emakethe awakwazi ukuhlangabezana namandla owamemezelayo. Nasi isithombe nevidiyo ye-SPD eqhume ekuhlolweni kwamanje kokuhlinzwa (Imax 40kA):

Idivayisi ephansi yokuvikelwa kokuvikela iqhumekile

Ukuphepha kweDivaysi Yokuvikelwa Kwesisindo (SPD)

Noma kunjalo kunakwa okumbalwa ekuphepheni kwensimbi yokuvikela ukuqhuma. Kodwa-ke, i-SPD eyakhiwe kabi ingaba yingozi ngokweqile futhi ingenye yezimbangela ezinkulu zengozi yomlilo. Ngezansi kunezithombe ezishisiwe ze-SPD:

UL Warns of Potentially Abayingozi Surge Protectors

I-NORTHBROOK, i-Ill., July 29, 2016 - Lokhu okulandelayo isaziso esivela ku-UL ukuthi abavikeli abaqhamuka ngezansi bangabangela ingozi yomlilo. Umkhiqizo awuhambisani namazinga okuphepha we-UL futhi awugunyaziwe ukuphatha i-UL Mark ye-United States noma i-Canada.

Umbiko we-ABC News - Isexwayiso sabaninikhaya: Idivayisi yokuvikelwa ekhaya ingabangela ngempela umlilo

CARY, NC (WTVD) - UMnyango Wezomlilo waseCary uxwayisa abaninikhaya kulandela umlilo wesihlanu oxhunywe kumvikeli wokwanda edolobheni eminyakeni emine edlule.
“Saqala ukubona lezi zinhlobo zomlilo ezenzekile, ikakhulukazi lowo owawunomonakalo omkhulu ekhaya. Umlilo okhuphuke ukukhuphuka kwe-vinyl siding yomuzi, wagcina ungene esikhaleni se-attic, wagcina usungene ophahleni, ”kuchaza uCary FD Capt. Scott Benninghoff.

I-SPD / MOV yi-Victim of Overnight Overvoltage (TOV)

I-SPD engakhiwe kahle noma engasetshenziswanga kahle futhi i-MOV engavikelekile ingangena ekuthumeni okufudumele, okuholela ekubeni isifundazwe esifushane, ukushisa, ukubhema nokukhwabanisa umlilo ngenxa yokuthi:

  • Ukuphela kokuphila
  • Ukweqisa okungavamile / Ukuphelelwa isikhathi okwesikhashana (TOV)
  • Phuma ngamandla angalindelekile

I-MOV noma i-SPD yibavikeli be-Overvoltage Yesikhashana (noma iqhubekela phambili) kodwa izisulu ze-Overnight Overvoltage.

I-MOV Ishiswe Ngaphansi Kokukhokhiswa Kwesikhashana (TOV)

Isixazululo Sokuphepha Kwedivayisi Yokuvikela - I-TPAE Technology

I-Prosurge ithuthukise ubuchwepheshe be-TPAE (Thermally Protected Arc Extinguishing) ukuxazulula inkinga yezokuphepha ye-SPD futhi sinobuchwepheshe obunelungelo lobunikazi e-USA, Germany, Korea nase China.

Ngokuya ngobuchwepheshe be-TPAE, sithuthukise ingxenye yethu eyinhloko ye-SPD - i-SMTMOV ne-PTMOV.

I-PTMOV

Ungabona ukuthi umkhiqizo wethu uhlala uphephile kanjani kusitutation eqhubekayo yevoltage ngenkathi umkhiqizo womncintiswano wethu usha.

Ku-415Vac ukuphelelwa yisikhathi okwesikhashana, i-SMTMOV yethu ne-TAPE ubuchwepheshe buyasula lesi simo esingavamile futhi sihlala siphephile

Ku-415Vac ukuphelelwa yisikhathi okwesikhashana, ingxenye ye-SPD ngaphandle kwekhono le-TPAE elishiswe kabi.

Esivivinyweni esingezansi, ama-SPD amabili ahlolwa ngaphansi kwe-TOV (i-overvoltage yesikhashana). Bona ukuthi umphumela wehluka kanjani nge-SPD ngokuvikelwa kwe-TPAE ne-SPD ngaphandle kokuvikelwa kwe-TPAE:

Nge-Prosurge ubuchwepheshe obunikazi be-TPAE, i-SPD ihluleka-iphephile futhi ivikelekile.

Ngaphandle kwedivayisi yokucisha i-arc, i-SPD ibangele ukubhema nomlilo, okuzoba yingozi kumjikelezi.
