Kodi Chipangizo Choteteza Kuthamanga kwa Mtundu 1 + 2 Chophatikizana N'chiyani?

Mu zomangamanga zamagetsi zamakono, zipangizozi nthawi zambiri zimayikidwa pakhomo lolowera kapena pa bolodi lalikulu logawa kuti ziteteze zonse njira yotetezera mafunde amagetsi.

Kumvetsetsa ubale pakati pa Chipangizo choteteza ma surge cha mtundu wa 1+2 poyerekeza ndi mtundu wa 2 ndikofunikira popanga chitetezo chogwirizana cha mafunde m'maukonde amagetsi a mafakitale ndi amalonda.

Mosiyana ndi muyezo Chipangizo choteteza matenda a surge cha mtundu wa 2, zomwe zimateteza makamaka ku mphezi zosalunjika ndi kugwedezeka kwamphamvu, Chipangizo choteteza kugwedezeka kwa mtundu wa 1 + 2 Yapangidwa kuti igwire ntchito yolimbana ndi mphamvu yamagetsi amphamvu kwambiri komanso kuchepetsa mphamvu yamagetsi yotsika pansi.

Machitidwe ambiri otetezera kulowa kwa mautumiki amaphatikizidwa Zoteteza DIN pa mafunde a sitima yopangidwira makamaka kuti ipereke mphamvu zambiri zotulutsira komanso kutsatira malamulo Chipangizo choteteza kugwedezeka kwa IEC 61643-11 miyezo.

Zitsanzo za ukadaulo woteteza woterewu zitha kupezeka m'magawo apadera Mayankho a mtundu wa 1+2 SPD yopangidwira malo ogawa magetsi m'mafakitale.

Kodi mtundu wa 1 + 2 SPD umagwira ntchito bwanji ngati choletsa kugwedezeka kwa magetsi?

A Mtundu Wophatikizana 1+2 SPD imagwira ntchito ngati choletsa magetsi a mphezi mwa kusuntha mosamala mafunde amphamvu kwambiri kuchokera ku zochitika za mphezi kupita ku dongosolo lokhazikika.

Zipangizozi zapangidwa kuti zipirire miyezo yokhazikika Mafunde a 10/350 μs a mphezi, zomwe zikuyimira mphamvu ya mphezi yolunjika yomwe imalowa mu netiweki yamagetsi.

Njira Yotulutsira Mphamvu ya Mphezi

Pa nthawi ya kugunda kwa mphezi kapena kugwedezeka kwamphamvu, chipangizo choteteza mphezi imayendetsa mwachangu zinthu zoteteza mkati monga:

• zitsulo zoyezera oxide (MOV)

• machubu otulutsira mpweya (GDT)

• nyumba zopinga za spark

Zigawozi zimapangitsa mphamvu ya mafunde kupita ku dziko lapansi pamene zimachepetsa mphamvu ya mafunde kufika m'madera otsika.

Mu machitidwe opangidwa motsatira Malo oteteza mphezi a LPZ, Ma SPD a Mtundu 1+2 nthawi zambiri amaikidwa pakadutsa pakati pa LPZ 0 ndi LPZ 1.

Kuyika kumeneku kumalepheretsa kufalikira kwa mphamvu zambiri m'malo oyika magetsi.

Ndi Mapulogalamu Ati Omwe Amafunikira Ma SPD Ophatikizana a Mtundu 1 + 2?

A Mtundu Wophatikizana 1+2 SPD imagwiritsidwa ntchito kwambiri m'makina amphamvu komwe chitetezo cha mphezi ndi kuchepetsa kukwera kwa mafunde zimafunika.

Mapulogalamu Odziwika

Makonzedwe wamba ndi awa:

• mapanelo olowera ntchito m'nyumba zamalonda

• machitidwe ogawa mphamvu zamafakitale

• makina amphamvu a photovoltaic

• malo olumikizirana mauthenga

• zipinda zogwirira ntchito

Malo awa amafunika kukhala olimba chitetezo chachikulu cha magiya ogawa chifukwa mafunde a mphezi olowa kudzera m'mizere yamagetsi angayambitse kuwonongeka kwakukulu kwa zida.

Kukhazikitsa mafakitale nthawi zambiri kumagwiritsa ntchito dongosolo loteteza mafunde otuluka m'madzi, komwe mitundu yambiri ya SPD imayikidwa pamlingo wosiyana wa netiweki yamagetsi.

Kapangidwe kabwino ka SPD

Kapangidwe kameneka kamatsimikizira kuti mphamvu ya mafunde imachepa pang'onopang'ono kudutsa njira yotetezera mafunde amagetsi, kukonza kudalirika kwa zida ndi chitetezo cha ntchito.

Kodi Mungasankhe Bwanji DIN Rail Type 1+2 Surge Protector?

Kusankha cholondola Chitetezo cha DIN cha mafunde a njanji imafuna kuwunika momwe magetsi amagwirira ntchito komanso momwe zinthu zilili.

1. Yesani Voltage ya System ndi Earthing Configuration

SPD iyenera kufanana ndi dongosolo lokhazikitsa maziko.

Makonzedwe wamba ndi awa:

• Dongosolo loteteza kuphulika kwa TT

• Dongosolo loteteza kuphulika kwa TN-S

Dongosolo lililonse limafuna mawaya enaake a SPD kuti zitsimikizire kuti mafunde akutuluka bwino padziko lapansi.

2. Onani momwe mphezi ikuonekera panopa

Kwa Mtundu Wophatikizana 1+2 SPD, magawo ofunikira a magwiridwe antchito ndi awa:

• mlingo wamakono wa impulse (Iimp)

• kutulutsa kwamadzimadzi (Mu)

• mphamvu yotulutsa mphamvu yayikulu (Imax)

Mphamvu yamagetsi yowonjezereka imafunika m'madera omwe mphezi zimafalikira kapena m'malo omwe ali ndi makina oteteza mphezi akunja.

3. Onetsetsani kuti mukutsatira miyezo ya IEC

Wodalirika chipangizo choteteza mafunde a mafakitale ayenera kutsatira Chipangizo choteteza kugwedezeka kwa IEC 61643-11 zofunikira, zomwe zimafotokoza:

• mawonekedwe a mafunde oyesera kukwera

• magulu a zipangizo

• magwiridwe antchito achitetezo

Kutsatira malamulo kumatsimikizira kuti malamulo apadziko lonse lapansi okhudzana ndi chitetezo chamagetsi akugwirizana.

4. Ganizirani Malo Oyikira ndi Kukonza

Zamakono kwambiri Zoteteza DIN pa mafunde a sitima ndi zipangizo zoyendetsera zomwe zimapangidwa kuti zikhazikitsidwe m'magawo ogawa magetsi wamba.

Kusankha SPD yaying'ono koma yolimba kwambiri kumapangitsa kuti zikhale zosavuta kuphatikiza ma switchboard a mafakitale ndi makabati owongolera.

Zida zina zopangira chitetezo cha mafunde zimapezeka kudzera mu Mayankho aukadaulo woteteza ku surge ku Leikexing, pomwe mafunso okhudza polojekitiyi akhoza kutumizidwa kudzera upangiri waukadaulo.

Mapeto

A Mtundu Wophatikizana 1+2 SPD imagwira ntchito yofunika kwambiri poteteza zomangamanga zamagetsi ku mafunde amagetsi komanso kugwedezeka kwa magetsi.

Poyerekeza Chipangizo choteteza ma surge cha mtundu wa 1+2 poyerekeza ndi mtundu wa 2, kusiyana kwakukulu kuli mu kuthekera kogwiritsa ntchito mphamvu ya mphezi ndi malo oyika mkati mwa ulamuliro wa chitetezo cha mafunde.

Mwa kuphatikiza Zipangizo zoteteza ku mafunde a mtundu wa 1+2 kulowa m'magawo olowera ntchito ndikuwagwirizanitsa ndi omwe ali pansi pa mtsinje Zipangizo zodzitetezera ku ma surge a mtundu wa 2, mainjiniya amatha kumanga malo odalirika dongosolo loteteza mafunde otuluka m'madzi zomwe zimateteza zida zamafakitale ndi zoyika zamagetsi.
