Chipangizo Choteteza Kuthamanga: Kodi Ndi Chiyani Ndipo Chimagwira Ntchito Motani?

---

Kukwera kwa magetsi kumawononga zida mwakachetechete, kumafupikitsa nthawi yogwira ntchito, komanso kumayambitsa nthawi yogwira ntchito yosakonzekera. Nthawi zambiri ndimaona kuti chiopsezochi chimachepetsedwa mpaka kulephera kuonekera m'machitidwe ofunikira.

A chipangizo choteteza kugwedezeka kwa mafunde Yapangidwa kuti iteteze zida zamagetsi ndi zamagetsi ku zochitika zosakhalitsa za overvoltage mwa kusuntha mphamvu yochulukirapo kupita pansi mosamala isanawonongeke.

M'magawo omwe ali pansipa, ndifotokoza momwe mitundu yosiyanasiyana ya zida zotetezera ma surge imagwirira ntchito, komwe zimagwiritsidwa ntchito, komanso momwe mainjiniya ayenera kusankha njira yoyenera yogwiritsira ntchito makina amafakitale.

Kodi Zipangizo Zoteteza Mtundu 1 ndi Mtundu 2 Zimagwira Ntchito Bwanji?

Zochitika zosiyanasiyana za kukwera kwa magetsi zimafuna njira zosiyanasiyana zodzitetezera. Zipangizo zodzitetezera za mtundu 1 ndi mtundu 2 zimagwira ntchito limodzi poletsa kukwera kwa magetsi pamalo osiyanasiyana mu dongosolo lamagetsi, zomwe zimaletsa mphamvu zowononga kuti zisafike pa katundu wovuta. Chipangizo chodzitetezera cha kukwera kwa magetsi chimagwira ntchito poyang'anira kuchuluka kwa magetsi ndikuyankha nthawi yomweyo pamene kukwera kwa magetsi kwanthawi yayitali kupitirira malire odziwika. Kukwera kumeneku nthawi zambiri kumachitika chifukwa cha kugunda kwa mphezi, ntchito zosinthira zamagetsi, kapena katundu waukulu woyambitsa. Kusiyana kwakukulu pakati pa zipangizo za mtundu 1 ndi mtundu 2 kuli mu kuti ndi Bwanji amaletsa mphamvu ya mafunde.

A chipangizo choteteza matenda a surge cha mtundu 1 imayikidwa pakhomo lolowera, pamwamba pa bolodi lalikulu logawa. Yapangidwa kuti igwire ntchito yolimbana ndi kukwera kwamphamvu kwamphamvu kochokera ku mphezi kapena maukonde amagetsi. Zipangizozi zimatha kutulutsa mphamvu ya mphezi pang'ono padziko lapansi mosadalira chitetezo cham'mwamba.

Mosiyana ndi zimenezi, chipangizo choteteza matenda a surge cha mtundu wa 2 imayikidwa pansi pa madzi, nthawi zambiri mkati mwa mapanelo ogawa. Imachepetsa kukwera kwa madzi komwe kumadutsa mu Mtundu 1 kapena komwe kumapangidwa mkati mwa kusinthana kwa zida. Pamodzi, njira yotetezera iyi yophatikizana imachepetsa kwambiri kupsinjika kwa zamagetsi pansi pa madzi.

Mu mafakitale enieni, kudalira gawo limodzi loteteza sikukwanira kawirikawiri. Chitetezo cha Mtundu 1 ndi Mtundu 2 chogwirizana chimatsimikizira kuti mphamvu ya mafunde ikuchepa pang'onopang'ono, kusunga milingo yamagetsi mkati mwa malire olekerera zida.

Momwe Chipangizo Chotetezera cha Mtundu 1 Chimagwirira Ntchito Kuwonjezeka kwa Mphamvu Zapamwamba

Zipangizo za mtundu woyamba zimapangidwa kuti zizitha kupirira mafunde amphamvu komanso kugwira ntchito popanda chitetezo cha mafunde akumtunda.

• Yaikidwa pakhomo lalikulu la utumiki

• Yopangidwira kutulutsa mphamvu yamagetsi

• Kawirikawiri amayesedwa malinga ndi miyezo ya mafunde a 10/350 μs

• Zofunikira pa malo omwe mphezi zimachitikira

Izi zimapangitsa chipangizo choteteza kugwedezeka mtundu 1 mayankho ofunikira kwambiri pa mafakitale, malo osungira deta, ndi mapulojekiti omanga nyumba okhala ndi mawaya amagetsi omwe akubwera.

Momwe Chipangizo Chotetezera Mtundu wa 2 Chimalepheretsa Kupitirira Mphamvu Kwambiri

Zipangizo za mtundu wachiwiri zimayang'ana kwambiri kuchepetsa mphamvu yamagetsi m'malo mogwiritsa ntchito mphamvu yamagetsi.

• Yaikidwa m'mabwalo ogawa magawo

• Yankhani mwachangu ku zinthu zocheperako mphamvu

• Tetezani ma PLC, ma drive, ndi kuwongolera zamagetsi

• Chepetsani kupsinjika kwa kutentha kwa thupi

Chosankhidwa bwino chipangizo choteteza kugwedezeka kwamphamvu mtundu wa 2 amachepetsa kwambiri kuchuluka kwa kulephera kwa nthawi yayitali kwa zida zodziwikiratu.

Chifukwa Chake Chitetezo Chogwirizana N'chofunika

Kugwiritsa ntchito Mtundu 1 kapena Mtundu 2 kokha kumabweretsa mipata yoteteza.

• Mtundu 1 wopanda Mtundu 2 umasiya magetsi otsala osayang'aniridwa

• Mtundu wachiwiri wopanda Mtundu woyamba uli ndi chiopsezo chachikulu cha kuchuluka kwa matenda

• Machitidwe ogwirizana amathandiza kuti IEC itsatire malamulo

• Nthawi yosamalira imakulitsidwa

Kodi Zipangizo Zoteteza Kuthamanga kwa Mtundu 1 ndi Mtundu 2 Zimagwiritsidwa Ntchito Kuti?

Kuyika molakwika kumachepetsa mphamvu yoteteza. Zipangizo zoteteza ma surge a mtundu 1 ndi mtundu 2 ziyenera kugwiritsidwa ntchito pamalo enaake mu dongosolo lamagetsi kuti ziwongolere kuyenda bwino kwa mphamvu ya ma surge.

Kugwiritsa ntchito n'kofunika mofanana ndi kusankha chipangizo. Nthawi zambiri ndimaona zipangizo zodzitetezera ku mafunde zikugwira ntchito bwino chifukwa chakuti zayikidwa pamalo olakwika. Zipangizo za mtundu 1 ndi mtundu 2 zimagwira ntchito zosiyanasiyana mkati mwa kapangidwe ka magetsi.

Zipangizo za mtundu woyamba zimagwiritsidwa ntchito pamene makina amagetsi amalumikizana ndi maukonde akunja. Izi zikuphatikizapo malo olowera ogwiritsira ntchito magetsi, kulumikizana kwa mzere wopita pamwamba, ndi malo okhala ndi makina oteteza mphezi akunja. Ntchito yawo ndikuletsa mafunde akuluakulu asanafike pachimake.

Zipangizo za mtundu wachiwiri zimagwiritsidwa ntchito pafupi ndi katundu wovuta. Zimateteza makina odziyimira pawokha, ma drive a mota, mapanelo a zida, ndi zida za IT ku ma switching surges opangidwa mkati ndi ma residual overvoltage.

Kwa mafakitale omwe akufuna chitetezo chogwirizana ndi malamulo komanso chodalirika, kuphatikiza chipangizo choteteza matenda a surge cha mtundu 1 Pakhomo lolowera ntchito yokhala ndi chitetezo cha Mtundu 2 pansi pake ndi njira yovomerezeka kwambiri yaukadaulo.

Mapulogalamu Odziwika a Chipangizo Choteteza Kuthamanga kwa Mtundu 1

• Ma switchboard akuluakulu okhala ndi mphamvu zochepa

• Malo okhala ndi njira zotetezera mphezi zakunja

• Mafakitale opanga magetsi omwe amagwiritsa ntchito mawaya amagetsi ozungulira

• Kukhazikitsa mphamvu zongowonjezwdwanso

Malo awa amakhala ndi mphamvu zambiri zoyendera panyanja.

Mapulogalamu Odziwika a Chipangizo Choteteza Kuthamanga kwa Mtundu Wachiwiri

• Mapanelo olamulira ndi ma MCC

• Makabati odziyimira pawokha ndi a PLC

• Nyumba zamalonda zokhala ndi zamagetsi zodziwikiratu

• Mabodi ogawa mafakitale

Apa, chipangizo choteteza matenda a surge cha mtundu wa 2 imayang'ana kwambiri kuchepetsa kukwera kwa magetsi komwe kumawononga zida zamagetsi pakapita nthawi.

Tebulo Loyerekeza Ntchito

Kodi Mungasankhe Bwanji Mtundu Woyenera wa Chipangizo Choteteza Kuthamanga?

Kusankha mtundu wolakwika wa chipangizo choteteza kugwedezeka kwa mafunde kumabweretsa chitetezo chabodza. Kusankha koyenera kumadalira mtunda wa makina, kuchuluka kwa kugwedezeka kwa mafunde, komanso kukhudzidwa kwa zida.

Kusankha chipangizo choteteza mafunde sikuyenera kutengera momwe zinthu zilili panopa. Ndikupangira kuyamba ndi kuwunika kwa dongosolo. Dziwani makhalidwe a mphamvu zomwe zikubwera, mtundu wa nthaka, ndi kufunika kwa katundu wotetezedwa.

Malo omwe ali ndi mphezi kapena omwe amaperekedwa ndi zingwe zopita pamwamba amafunika mphamvu chipangizo choteteza kugwedezeka mtundu 1 pakhomo lolowera ntchito. Zipangizozi ziyenera kutsatira miyezo ya IEC 61643 ndikugwira ntchito yotulutsa madzi ambiri popanda kulephera.

Pa chitetezo chamkati, mgwirizano chipangizo choteteza matenda a surge cha mtundu wa 2 ziyenera kusankhidwa kutengera mphamvu yamagetsi, mulingo woteteza (Kukwera), ndi nthawi yoyankhira. Mitengo Yotsika Kwambiri nthawi zambiri imapereka chitetezo chabwino pamagetsi osavuta kugwiritsa ntchito.

Chofunikanso ndi mtunda wogwirizana, kutalika kwa mawaya, ndi kukana kwa nthaka. Kusakhazikika bwino kumatha kuchepetsa kwambiri mphamvu ya SPD, mosasamala kanthu za kuchuluka kwa chipangizocho.

Zofunikira Zosankha Zaukadaulo

• Voltage ya dongosolo lodziwika (Uc)

• Kutulutsa mphamvu yamagetsi (In / Imax)

• Mulingo woteteza mphamvu yamagetsi (Kukwera)

• Malo okhazikitsa

• Kutsatira miyezo ya IEC

Zolakwa Zodziwika Kwambiri Zosankha

• Kugwiritsa ntchito zipangizo za Type 2 popanda chitetezo cham'mwamba

• Kuchulukitsa mavoti apano koma osanyalanyaza ma Up values

• Kunyalanyaza khalidwe la dongosolo lokhazikitsa nthaka

• Kuyika ma SPD kutali kwambiri ndi katundu wotetezedwa

Ndondomeko Yosankhidwa Yovomerezeka

• Kuwonekera kwakunja kwa mafunde → Mtundu 1 umafunika

• Zipangizo zamagetsi zomvera → Mtundu wachiwiri umafunika

• Machitidwe a mafakitale → Chitetezo chogwirizana

• Nthawi yopumira yofunika kwambiri → Zigawo za SPD zosafunikira

Mapeto

Chosankhidwa bwino chipangizo choteteza kugwedezeka kwa mafunde Njira yophatikiza chitetezo cha Mtundu 1 ndi Mtundu 2 ndikofunikira kwambiri poteteza machitidwe a mafakitale ndikuwonetsetsa kuti magwiridwe antchito ndi odalirika kwa nthawi yayitali.
