Kodi Kusiyana Pakati pa Woteteza Kuthamanga ndi Woteteza Kuthamanga N'chiyani?

Nthawi zambiri ndimaona zoteteza ma surge protectors ndi zoletsa ma surge akugwiritsidwa ntchito mosinthana. Kusokonezeka kumeneku kumabweretsa kusankha kolakwika kwa zipangizo ndi chitetezo chosakwanira m'makina amagetsi.

Choteteza kukwera kwa mafunde vs choletsa kukwera kwa mafunde Si mkangano wa mawu. Umasonyeza zolinga zosiyanasiyana zotetezera, mfundo zogwirira ntchito, ndi malo ogwiritsira ntchito mkati mwa kapangidwe ka chitetezo cha mafunde. Kumvetsetsa kusiyana ndikofunikira popanga makina odalirika amagetsi a mafakitale, amalonda, ndi zomangamanga.

Kodi Oteteza Opaleshoni ndi Ogwira Ntchito Zopaleshoni Zimagwira Ntchito Mosiyanasiyana Motani?

Kusiyana kwakukulu pakati pa choteteza ma surge ndi choletsa ma surge kuli mu momwe amachitira zinthu pazochitika za overvoltage ndi kuchuluka kwa mphamvu ya ma surge yomwe adapangidwira kuthana nayo.

Momwe Otetezera Othamanga Amagwirira Ntchito

A choteteza kugwedezeka nthawi zambiri ndi chipangizo choteteza kugwedezeka kwa mpweya (SPD) imayikidwa mkati mwa makina ogawa magetsi. Ntchito yake yayikulu ndikutseka ma overvoltage osakhalitsa ndikuchepetsa ma voltage otsala kufika pamlingo wotetezeka wa zida zotsikira pansi.

Kuchokera pamalingaliro a uinjiniya, momwe zotetezera ma surge zimagwirira ntchito tingafupikitse motere:

• Gwiritsani ntchito limodzi ndi dera lamagetsi

• Khalani osagwira ntchito nthawi zonse pamene magetsi ali abwinobwino

• Sinthani mwachangu kupita ku mkhalidwe wotsika wa impedance panthawi ya surge

• Sinthani mphamvu yamagetsi kuti ifike pansi mkati mwa ma microseconds

Oteteza ma surge nthawi zambiri amagwiritsa ntchito ma MOV, ma TVS diode, kapena ma hybrid circuits ndipo amagawidwa m'magulu awiri. Mtundu 1, Mtundu 2, kapena Mtundu 3 SPD kutengera malo oyikamo ndi momwe zimakhudzira kukwera kwa madzi.

Momwe Ogwira Ntchito Zogwirira Ntchito

A choletsa kukwera kwa mpweya Yapangidwa makamaka kuti iteteze makina amphamvu kwambiri ku mphezi ndi kugwedezeka kwa magetsi. Imagwira ntchito popereka njira yowongolera yotulutsira magetsi pamene magetsi apitirira mulingo wake woteteza.

Momwe zotchingira kuthamanga kwa magazi zimagwirira ntchito zimasiyana m'njira zazikulu:

• Yopangidwira ma voltage apamwamba a dongosolo

• Gwirani ntchito ndi mafunde amphamvu kwambiri

• Kawirikawiri imayikidwa pansi mpaka pansi

• Yang'anani kwambiri pa chitetezo cha kutentha m'malo mwa mphamvu yochepa yotsalira

Zinthu zoletsa kuthamanga kwa madzi zimapezeka kwambiri m'mizere yotumizira magetsi, m'malo osungira magetsi, ndi m'zida zogwiritsira ntchito m'malo mogwiritsa ntchito mkati mwa nyumba.

Kusiyana Kwakukulu kwa Zaukadaulo

The kusiyana pakati pa choteteza kugwedezeka ndi choletsa kugwedezeka Sikuti ndi kukula kokha, koma cholinga cha kapangidwe:

• Oteteza ma surge amayang'ana kwambiri kuteteza zamagetsi zomwe zimakhudzidwa ndi ma surge

• Zoletsa kuthamanga kwa madzi zimayang'ana kwambiri pa kuteteza kutenthetsa ndi zida zamagetsi

• Ma SPD amaika patsogolo chitetezo chamagetsi otsika

• Ogwira ntchito yomanga nyumba amaika patsogolo mphamvu yamagetsi okwera kwambiri

Kodi Oteteza Opaleshoni ya Surge vs Surge Arresters Amagwiritsidwa Ntchito Kuti?

Zoteteza kugwedezeka kwa magetsi ndi zoletsa kugwedezeka kwa magetsi zimagwiritsidwa ntchito m'malo osiyanasiyana mu dongosolo lamagetsi kutengera kuchuluka kwa magetsi, kukhudzana ndi kugwedezeka kwa magetsi, komanso kukhudzidwa kwa zida.

Kugwiritsa Ntchito Kawirikawiri kwa Oteteza Odwala

Zoteteza ma surge zimagwiritsidwa ntchito kwambiri m'malo okhala ndi ma voltage otsika komanso apakati pomwe zida zamagetsi ziyenera kutetezedwa ku ma voltage osakhalitsa.

Ntchito zodziwika bwino zikuphatikizapo:

• Mapanelo akuluakulu ndi ogawa

• Makabati owongolera mafakitale

• Makina odziyimira pawokha ndi ma PLC

• Nyumba zamalonda ndi malo osungira deta

• Chitetezo cha nyumba yonse machitidwe

Mu makina opangira magetsi, zoteteza ma surge zimagwiritsidwa ntchito m'njira yosiyana pogwiritsa ntchito Mtundu 1, Mtundu 2, ndi Mtundu 3 SPD kuchepetsa pang'onopang'ono mphamvu ya kukwera kwa madzi.

Mayankho ambiri pamlingo womanga nyumba amadalira mgwirizano Chitetezo cha AC pa mafunde kuyang'anira kukwera kwa mafunde oyendetsedwa ndi gridi asanafike pa katundu wovuta.

Ntchito Zachizolowezi za Surge Arresters

Zoletsa kugwedezeka kwa magetsi zimagwiritsidwa ntchito pamene mphamvu ya kugwedezeka kwa magetsi ndi yokwera kwambiri ndipo chitetezo cha zida chiyenera kutetezedwa:

• Mizere yotumizira ndi kugawa zinthu

• Malo osinthira magetsi ndi malo osinthira magetsi

• Ma transformer ndi makina akuluakulu ozungulira

• Kukhazikitsa kwamagetsi amphamvu panja

Mu mafakitale a mphamvu zongowonjezwdwanso ndi makina ogwirira ntchito, zomangira zitha kugwiritsidwanso ntchito pamabwalo a DC, komwe zaperekedwa Chitetezo cha DC pa mafunde njira zofunika kuthana ndi kupsinjika kosalekeza kwa polarity.

Chifukwa Chake Nkhani Yogwiritsira Ntchito Ndi Yofunika

Kuyika choletsa kugwedezeka kwa magetsi mkati mwa gulu lowongolera lamagetsi otsika sikutanthauza chitetezo cha zida. Mofananamo, kudalira zoteteza kugwedezeka kwa magetsi kokha pa mawonekedwe amagetsi kungapangitse zida zakumtunda kukhala ndi mphamvu ya mphezi.

Kugwiritsa ntchito bwino kumadalira kumvetsetsa komwe kumachokera pakukwera kwa mphamvu, kuchuluka kwa mphamvu, ndi cholinga choteteza.

Kodi Mungasankhe Bwanji Pakati pa Surge Protector ndi Surge Arrester?

Kusankha pakati pa choteteza ma surge ndi choletsa ma surge kumadalira mphamvu yamagetsi ya dongosolo, kuchuluka kwa ma surge, komanso mphamvu ya zida zotetezedwa.

Kusankha Kutengera Mlingo wa Machitidwe

Njira yosavuta yosankhira:

• Gwiritsani ntchito choletsa kugwedezeka poteteza zida zamagetsi amphamvu ku mphezi ndi kugwedezeka kwa magetsi

• Gwiritsani ntchito choteteza ma surge (SPD) poteteza zida zamagetsi otsika ku ma voltage osakhalitsa

Mu malo ambiri, zipangizo zonse ziwiri zimafunika pazigawo zosiyanasiyana za makina amagetsi.

Kugwirizana ndi Mitundu ya SPD

M'makina otsika mphamvu zamagetsi, kusankha mtundu woyenera wa SPD ndikofunikira kwambiri:

• Mtundu 1 SPD: Yaikidwa pakhomo lolowera, imagwira ntchito yowunikira pang'ono

• Mtundu wachiwiri wa SPD: Yoyikidwa pa mapanelo ogawa, imachepetsa mphamvu yotsalira yamagetsi

• Mtundu wa 3 SPD: Yayikidwa pafupi ndi katundu wovuta

Njira yogwirizana iyi imatsimikizira kuti zinthu zikuyenda bwino chitetezo cha nyumba yonse ndi kudalirika kwa machitidwe a mafakitale.

Zoganizira za Uinjiniya ndi Zogula

Posankha pakati pa mayankho, mainjiniya ayenera kuwunika:

• Mphamvu yogwira ntchito yopitilira (MCOV)

• Kuyeza kwa mphamvu yamagetsi ndi mphamvu yamagetsi

• Mulingo woteteza mphamvu yamagetsi (Kukwera)

• Mikhalidwe yokhazikika ndi yogwirizana

• Malo okhazikitsa

Pa makina ovuta kapena mapangidwe osakanikirana a AC/DC, mainjiniya ambiri amatsimikiza kusankha kwawo kudzera mu upangiri waukadaulo kupewa kugwiritsa ntchito molakwika ndikuwonetsetsa kuti miyezo ikutsatira malamulo.

Mapeto

Choteteza kukwera kwa mafunde vs choletsa kukwera kwa mafunde ndi chisankho cha pamlingo wa dongosolo, osati kufananiza zinthu. Pomvetsetsa momwe chipangizo chilichonse chimagwirira ntchito komanso komwe chiyenera kugwirira ntchito, mainjiniya amatha kupanga njira zodzitetezera zogwirira ntchito zomwe zimateteza bwino zomangamanga komanso zida zodziwikiratu.

FAQ

Kodi kusiyana kwakukulu pakati pa choteteza ma surge ndi choletsa ma surge ndi kotani?
