Kodi mungasankhe bwanji chipangizo choteteza chitetezo (SPD)?
Zida zoteteza Chitetezo (SPD) amagwiritsidwa ntchito pofuna kuteteza zipangizo zamagetsi kuti zisamangidwe (kuwombera) chifukwa cha mphezi kapena makina opangira katundu (anthu ambiri akhoza kunyalanyaza izi). Zingatengere mbali zina zamakono popanga zipangizo zoyenera kutetezera monga momwe pali magetsi ndi machitidwe osiyanasiyana.
Mndandanda wa IEC 61643 umatanthauzira mitundu ya 3 yodzitetezera zoteteza magetsi.
Lembani 1 kapena Kalasi I: Pezani 1 SPD akhoza kutulutsa mphepo yamkuntho yamphamvu ndipo imayikidwa pamakina opangira magetsi pamene nyumbayo imatetezedwa ndi njira ya chitetezo cha mphezi (ndodo, mphezi, ndi kutsitsa).
Gwiritsani ntchito 2 kapena Gulu lachiwiri: Chipangizo chotetezera choterechi (SPD) chimapangidwira kuti chikwaniritse zamakono zomwe zimayambitsa kuwombera kwa magetsi. Kawirikawiri, iwo amaikidwa pawunikira yaikulu yogawa. Pezani 2 SPD ndi SPD yotchuka kwambiri pamsika ndipo Prosurge ikuwapatsa zizindikiro zosiyana.
Gwiritsani ntchito 3 kapena Gulu lachitatu: Mtundu wa 3 SPDs umapangidwira kuchepetsa kuthamanga pa mapeto a zipangizo zowonongeka kotero kuti ali ndi mphamvu zochepa zowonjezera zamakono.

Kodi mtundu wa 1 SPD umachita bwino kuposa mtundu wa 2 SPD?
Osati kwenikweni. Mtundu wa 1 SPD umaphatikizapo kukhala wokhudzana ndi mbali iliyonse ya pakhomo, koma UL sungafanizire kugwira ntchito kwa mtundu wa 1 SPD poyerekeza ndi mtundu wa 2 SPD. UL amafufuzira kugwira ntchito kwa SPDs mofanana, mosasamala za mtundu wa SPD. UL amawonanso ma SPDs onse kuti apite opaleshoni yotetezeka mkati mwa malo omwe akufunidwa. Kuyambira ndi UL 1449 3rd Kusindikiza, Mtundu wa SPN wovomerezeka wa 1 udzaphatikizapo zipangizo zomwe poyamba zinkadziwika kuti Omangirira Sekondale ndipo ziphatikizapo zipangizo zambiri zomwe kale zinkadziwika kuti TVSS. Ndikofunika kumvetsetsa kuti zipangizo zamtundu wambiri zomwe zimagwiritsidwa ntchito pa Sekondale zinapangidwa ndi MCOV yapamwamba (Maximum Continuous Operating Voltage) kusiyana ndi zipangizo za TVSS. Ndipo popeza chiwerengero cha MCOV cha SPD chikhoza kuthandizira kuwonetsetsa bwino, ntchito yabwino ya kusankha kwa SPD iyenera kuphatikizidwa mosamala pa ziwerengero monga maulendo opitirira maola ambiri, magetsi amphamvu a IEEE, UL VPR, ndi kuchuluka kwa moyo wa moyo.
Kodi ndingapeze kuti SPDs kuti ndingateteze malo anga?
N'zosatheka kuteteza kuthamanga kwa magetsi kuchokera pakalowa pakhomo lanu kapena kupezeka mkati mwa malo anu. Pofuna kuteteza malo osamalidwa, njira yabwino kwambiri ndi njira yochezera. Monga momwe tawonetsera pazithunzi zotsatirazi, Institute of Electrical and Electronics Engineers (IEEE) yakhazikitsa magulu atatu kuti malo onse angathe kugawa, Malo A, B ndi C. Onani IEEE Standard C62.41.1 ndi C62.41.2 kuti mudziwe zambiri.
Gawo A: malo ogulitsira / zogulitsa ndi maulendo aatali a nthambi (mkati) (zovuta)
• Malo onse ogulitsa ambiri omwe 10m (30 ft) ochokera m'gulu B
• Zogulitsa zonse zoposa 20m (60 ft) kuchokera ku C C
Gulu B: Odyetsa, maulendo afupipafupi a nthambi ndi mapaipi opangira (m'nyumba)
• Zipangizo zamakono ogawa
• Mabasi ndi kufalitsa kwa chakudya
• Malo ogwiritsira ntchito kwambiri omwe ali ndi "zochepa" zogwirizana ndi polowemo
• Makina ounikira mu nyumba zazikulu
Gulu C: Mizere yowonjezera kunja ndi polowemo (kunja)
• Udontho wautumiki kuchokera pole kupita kumanga
• Kuthamanga pakati pa mita ndi gulu
• Mizere yapamwamba kuti isamange nyumba
• Mizere yolowera pansi kuti mupope bwino

Kodi ANSI / UL 1449 Buku Lachitatu Ndi Liti IEC 61643-1 - Kusiyana Kwambiri Kuyesedwa
Zotsatirazi zikuyesa kusiyana kwakukulu pakati pa mayesero a Underwriters Laboratory (UL) oyenerera kuti apange zipangizo zoteteza (SPDs); ANSI / UL 1449 Buku lachitatu ndi International Electrotechnical Commission (IEC) linkafunika kuyesa kwa SPDs, IEC 61643-1.
Dongosolo lachidule lachidziwitso (SCCR): Mphamvu yamakono yomwe SPD yoyesedwa imatha kupirira pamapeto pake pamene imagwirizanitsidwa, popanda kuphwanya pakhomo mwa njira iliyonse.
UL: Yesani mankhwalawa kawiri kawiri kuti muwone ngati mankhwala onsewa ndi opanda pake. Zonsezi (monga zatumizidwa) zimayesedwa; kuphatikizapo zitsulo zamakina varistors (MOVs).
IEC: Yesetsani kuyang'ana pa mapeto ndi mawonekedwe enieni kuti aone ngati ali ndi mphamvu zokwanira kuti athetse vutoli. Ma MOV amalowetsedwa ndi mkuwa wamakono ndipo fuseti yowonjezera imayikidwa mu mzere (kunja kwa chipangizo).

UL: Sakudziwa kufunikira kwa mayeso a Imax.
IEC: Chiyeso chozungulira cha ntchito chimagwiritsidwa ntchito pozungulira mpaka ku Imax point (yotsimikiziridwa ndi wopanga). Izi zikutanthauza kuti tipeze "malingaliro akhungu" […]
Kodi mungasankhe bwanji zipangizo zoyenera kutetezera kuti zikhale zotsegula?
Kusankha oyenera kumangidwa (s) ndichofunikira kwambiri kuti muteteze kuyika koyenera. Makina otetezedwa bwino a Lightning & Surge angapangitse kukalamba kwa SPD ndikulephera kwa zida zodzitetezera pakukhazikitsa komwe kumapangitsa kuwonongeka kwa makina oyambira pamtsinje, motero kuthana ndi chifukwa chachitetezo chomwe chikukhazikitsidwa.
Prosurge sipereka malamulo ndi zitsogozo zothandizira kulongosola kosayenerera kwa chitetezo chotsatira malingana ndi ntchito. Komabe ife timatsata IEC ndi UL kuunikira ndi miyezo yotetezera. Ndili ndi malingaliro athu timapereka dongosolo lokhazikika monga momwe zilili m'malamulo a muyezo, osati malamulo a Prosurge.
M'malo ogwiritsira ntchito mafakitale, chizoloŵezi ndicho kukhazikitsa njira yoteteza chitetezo chokhazikitsidwa pogwiritsa ntchito zipangizo zingapo zothandizira zomwe zimayikidwa pa magawo osiyanasiyana (LPZ). Phindu la njirayi ndiloti limapangitsa kuti mphamvu yowonongeka ikhale yoyandikana kwambiri ndi polojekiti yowonongeka ndi mpweya wotsika (wotetezedwa) pamtundu waukulu wa zowonongeka.

Kodi mphezi ingawononge chithunzi cha photovoltaic?
Mapulogalamu a photovoltaic ndi opanga makanema kwambiri ndipo kugunda kwa mphenzi kwachindunji kumangowononga. Palibenso vuto lina, monga kugunda kwa mphezi kungapangitse mpweya wothamanga pafupi ndi mphamvu ya dzuwa ndipo izi zikhoza kuwononga dongosolo. Inverter ndilofunika kwambiri kutetezedwa. Kawirikawiri, osokoneza adzaphatikizira otetezera-voltage otetezera awo oyendetsa. Komabe, popeza zigawozi zimangowonjezera zokhazokha, muyenera kulingalira pogwiritsa ntchito zipangizo zoteteza (SPD) payekha.
Kodi masewero a maseŵera amatsindiridwa ndi SPD?
M'mbuyomu, ena opanga agwiritsira ntchito masewero a joule m'mawu awo. Iwo sali ngati chizindikiro choyenera cha ntchito ya SPD ndipo sichizindikiridwa ndi mabungwe aliwonse. Prosurge sichikuthandizira mfundoyi.

Kodi mitundu yamagetsi yamagetsi ndi iti ku US ndi zosowa zawo zachitetezo?
Njira yogawa magetsi ku US ndiyo dongosolo la TN-CS. Izi zikutanthauza kuti otsogolera omwe salowerera ndi omwe amachititsa kuti azitha kulowera kuntchito, aliyense, malo kapena magulu omwe amachokera. Izi zikutanthauza kuti mawonekedwe otetezeka omwe salowerera (NG) mkati mwa SPD yowonjezera maofesi omwe amaikidwa pazitseko za polojekiti yautumiki ndizochepa kwambiri. Komanso kuchokera ku bond bond ya NG, monga momwe zimagwirira ntchito m'nthambi, kufunika kwa njira yowonjezera imeneyi ndikofunika kwambiri. Kuwonjezera pa njira yotetezera NG, ma SPD ena angaphatikizepo mzere-kuti-asalowerera (LN) ndi chitetezo cha mzere (line). Pulogalamu ya WYE yachitatu, kufunika kwa LL kutetezedwa kumakhala kokayikitsa ngati kutetezedwa kwa LN kumaperekanso chitetezo pa LL conducors.
Zosintha ku 2002 pulogalamu ya National Electrical Code® (NEC ®) (www.nfpa.org) yaletsa kugwiritsidwa ntchito kwa ma SPD pamagetsi osagawika a delta.
