Kodi pali ubale wotani pakati pa mphezi ndi chitetezo cha mafunde?

Kulephera kwa magetsi nthawi zambiri kumamveka molakwika. Nthawi zambiri ndimaona malo akuyika ndalama pakugwiritsa ntchito zipangizo zomangira pansi kapena zomangira magetsi, pomwe kuwonongeka kwa zipangizo zamkati kumapitirira kuchitika pambuyo pa mphepo yamkuntho.

Chitetezo cha kukwera kwa mpweya imayang'ana zotsatira zamagetsi za mphezi, osati kugunda kwa mphezi yokha. Mu machitidwe amakono amagetsi ndi owongolera, kumvetsetsa ubale womwe ulipo pakati pa mphezi ndi chitetezo cha mafunde ndikofunikira kwambiri popewa kuwonongeka kwa zida, nthawi yogwira ntchito, komanso zoopsa zachitetezo.

Chitetezo cha mphezi ndi mafunde si mitu yosiyana. Ndi zigawo zolumikizana za njira imodzi yotetezera magetsi yopangidwira kuwongolera mafunde osakhalitsa ndi mafunde amagetsi.

Kodi Zipangizo Zoteteza Kuthamanga Zimachepetsa Bwanji Kuthamanga Koyambitsidwa ndi Mphezi?

Kukwera kwa mphezi komwe kumachitika chifukwa cha mphezi kumayendetsedwa ndi zida zoteteza kukwera kwa mphezi zomwe zimachotsa mphamvu yamagetsi yosakhalitsa kuchoka ku zida zodziwikiratu ndikuyitulutsa pansi mosamala mkati mwa masekondi ang'onoang'ono.

Momwe Mphezi Imapangira Mafunde a Magetsi

Mphezi siifunika kugunda malo mwachindunji kuti iwononge. Zochitika za kuphulika kwa mphezi nthawi zambiri zimachitika kudzera mu:

• Mphezi yachindunji imagunda pamagetsi kapena mizere yazizindikiro

• Kugundana kwapafupi komwe kumayambitsa kulowetsedwa kwa maginito

• Kukwera kwa nthaka komwe kungakhudze machitidwe a nthaka

• Zochitika za mphezi za mbali yamagetsi zomwe zimatumizidwa kudzera mu gridi

Njira zimenezi zimapanga ma overvoltage amphamvu kwambiri omwe amafalikira mofulumira kudzera mwa ma conductor.

Udindo wa Zipangizo Zoteteza Kuwonjezeka

A chipangizo choteteza matenda a surge type 1 Yapangidwa mwapadera kuti igwire ntchito yokhudzana ndi mafunde amagetsi okhudzana ndi mphezi pakhomo lolowera. Imatha kutulutsa mphamvu yamagetsi pang'ono ndikuchepetsa kuchuluka kwa magetsi ochulukirapo asanafike mu dongosolo lamagetsi lamkati.

Ntchito zazikulu za chitetezo champhamvu chokhudzana ndi mphezi ndi izi:

• Kukanikiza kwamphamvu kwamagetsi

• Kutulutsa mphamvu zamagetsi zambiri

• Chitetezo cha kutchinjiriza zida pansi pa madzi

Mu malo ambiri okhazikitsa, chitetezo cha surge cha circuit breaker imaphatikizidwa kuti ipereke chitetezo cha overcurrent komanso kulamulira kusinthasintha kwa mafunde, kukonza mgwirizano ndi chitetezo cha dongosolo.

Chifukwa Chake Zosokoneza Zokha Sizokwanira

Anthu ophwanya malamulo amachitapo kanthu pang'onopang'ono kwambiri pazochitika zosakhalitsa. zotsekera ma circuit ndi chitetezo cha surge kudalira zida zotetezera mafunde amkati m'malo mogwiritsa ntchito njira zotenthetsera kapena maginito kuti muchepetse mafunde oyambitsidwa ndi mphezi.

Popanda zipangizo zodzitetezera ku mafunde, ma transients okhudzana ndi mphezi amadutsa m'ma breaker osayang'aniridwa.

Ndi Makampani Ati Omwe Amafunikira Chitetezo Chodzipereka cha Kuphulika kwa Mphezi?

Makampani omwe ali ndi zida zambiri zogwira ntchito, omwe ali ndi mawonekedwe akunja, kapena omwe amafunika nthawi yogwira ntchito nthawi zonse amafunika chitetezo chapadera cha mphezi ndi mafunde.

Magawo a Mafakitale Omwe Ali ndi Chiwopsezo Chachikulu

Makampani otsatirawa ali pachiwopsezo chachikulu cha zochitika zoyambitsidwa ndi mphezi:

• Kupanga magetsi ndi malo osinthira magetsi

• Mphamvu yongowonjezedwanso (PV ya dzuwa ndi mphepo)

• Malo olumikizirana mauthenga ndi deta

• Kupanga ndi kukonza zokha

• Mayendedwe ndi zomangamanga

Malo amenewa nthawi zambiri amaphatikiza mawaya ataliatali, zida zakunja, ndi zamagetsi zomwe zimakhudzidwa ndi mafunde - malo abwino kwambiri ofalitsira mafunde.

Kuwonetsedwa kwa AC ndi DC System

Mphezi imakhudza maukonde a AC ndi DC, koma njira yotetezera imasiyana:

• Malo ogwirizana ndi ntchito amadalira mgwirizano Chitetezo cha AC pa mafunde kuyang'anira ma transients a mphezi omwe amalowa kudzera mu makina ogawa magetsi.

• Ma solar arrays, mabatire, ndi ma DC control circuits amafunika kudzipereka Chitetezo cha DC pa mafunde kuthana ndi kupsinjika kosalekeza kwa polarity ndi kukwera kwa mphezi komwe kumachitika chifukwa cha mphezi pa ma conductor a DC.

Kugwiritsa ntchito zipangizo zoyesedwa ndi AC ku makina a DC ndi cholakwika chofala komanso chokwera mtengo.

Zotsatira za Chitetezo Chosakwanira

Popanda chitetezo chokwanira cha mphezi ndi mafunde, malo ogwirira ntchito amakumana ndi:

• Kulephera kwamagetsi mobwerezabwereza

• Kutayika kwa deta ndi kulephera kwa dongosolo lowongolera

• Kukonza kowonjezereka ndi nthawi yopuma

• Zoopsa zokhudzana ndi chitetezo ndi kutsata malamulo

Choncho, chitetezo chodzipereka cha surge ndi ndalama zodalirika, osati chongowonjezera chitetezo.

Kodi Mungapange Bwanji Dongosolo Logwirizana la Mphezi ndi Chitetezo cha Kuphulika kwa Madzi?

Chitetezo chogwira mtima cha mphezi ndi kukwera kwa mphepo chimapezeka kudzera mu mgwirizano pakati pa chitetezo cha mphezi zakunja, kukhazikika pansi, ndi zida zotetezera kukwera kwa mphepo mkati.

Lingaliro la Chitetezo cha Dongosolo

Dongosolo loteteza logwirizana nthawi zambiri limaphatikizapo:

1. Chitetezo cha mphezi zakunja (malo opumira mpweya, ma conductor otsikira pansi) kuti azilamulira njira zowomberera mwachindunji

2. Zipangizo zodzitetezera ku surge za mtundu 1 pakhomo lolowera ku mafunde otulutsa mphezi

3. Chitetezo chachiwiri cha kukwera kwa magazi pa mapanelo ogawa

4. Chitetezo cha malo ogwiritsira ntchito za zida zodziwikiratu

Chigawo chilichonse chimachepetsa mphamvu ya mafunde ndi mphamvu yotsalira pang'onopang'ono.

Kugwirizana Pakati pa Zipangizo

Kugwirizana bwino kumaonetsetsa kuti zipangizo zam'mwamba zikugwira ntchito ndi mphamvu zambiri pamene zipangizo zam'munsi zimapereka mphamvu zochepa.

Mfundo zazikulu zogwirizanitsa zinthu ndi izi:

• Kusankha kolondola kwa chipangizo choteteza matenda a surge cha mtundu 1 mavoti

• Kutalikirana kokwanira kapena kulekanitsa pakati pa magawo oteteza

• Kapangidwe kokhazikika komanso kogwirizana

A chophwanya chitetezo cha mafunde ingagwiritsidwe ntchito m'mapangidwe ena, koma iyenera kugwirizanitsidwa ndi magetsi ndi zida zodzitetezera kuti isagwiritsidwe ntchito molakwika.

Ubwino Wokhazikitsa ndi Kukhazikitsa

Ngakhale kapangidwe kabwino kwambiri koteteza mafunde kamalephera popanda maziko oyenera. Njira zabwino kwambiri ndi izi:

• Njira zoyambira pansi zotsika-impedance

• Ma waya afupiafupi, owongoka olumikizirana

• Kugwirizana kwa equipotential pakati pa machitidwe

Pa malo ovuta kapena madera omwe mphezi zimawavuta, mainjiniya ambiri amatsimikiza kapangidwe kawo kudzera mu upangiri waukadaulo kuonetsetsa kuti miyezo ikutsatira malamulo komanso kudalirika kwa dongosolo kwa nthawi yayitali.

Mapeto

Chitetezo cha kukwera kwa mpweya ndiye maziko amagetsi a chitetezo cha mphezi. Mwa kumvetsetsa kukwera kwa mphezi, kuzindikira mafakitale omwe ali pachiwopsezo, komanso kupanga njira zotetezera zogwirizana, mainjiniya amatha kuchepetsa kwambiri kuwonongeka kwa zida ndi kusokonekera kwa ntchito.
