Kodi cholinga cha chitetezo cha surge ndi chiyani?
Mu machitidwe amagetsi amakono, kukwera kwa mphamvu, kukwera kwa magetsi, ndi phokoso la mizere zimakhala zoopsa zobisika pazida zamagetsi ndi zomangamanga zamagetsi.Woteteza Wokwera(yomwe imadziwikanso kuti SPD, Surge Protective Device) ndi chitetezo chofunikira kwambiri ku zoopsa izi, chomwe chimagwira ntchito ngati chitetezo cha zida zogona komanso zamafakitale. Zhejiang C&J Electrical co., ltd. (yomwe imatchedwa C&J Electrical) imapereka yankho la SPD logwira ntchito bwino lomwe limakhazikitsa muyezo watsopano wodalirika woteteza ma surge.
Cholinga Chachikulu cha Mtetezi Woteteza Kuthamanga
Choteteza ma surge chimapangidwa kuti chiteteze chipangizo chilichonse chokhala ndi pulagi ya AC yokhazikika ku ma surge amphamvu omwe angawononge komanso kusokoneza, ma voltage spikes ndi phokoso la mzere lomwe limadutsa kudzera mu soketi yamagetsi. Taganizirani za chitetezo cha ma surge ngati inshuwaransi. Chimayang'anira ma voltage omwe akubwera ndipo chimachotsa mphamvu zamagetsi zochulukirapo kuchokera kuzipangizo zolumikizidwa pakagwa ma surge kapena ma surge, kuteteza kuwonongeka kwa zinthu zofunika, kutayika kwa deta, kapena ngozi zamoto.
Mosiyana ndi zida zamagetsi zoyambira (zomwe zimangowonjezera malo otulukira popanda chitetezo cha surge), chipangizo chodziperekaWoteteza Wokwera(SPD) idapangidwa kuti ithane ndi zovuta zinazake zamagetsi, kuphatikizapo:
- Kukwera kwa mphamvu: Mphamvu yamagetsi pang'onopang'ono imawonjezera ma milliseconds okhalitsa mpaka mphindi
- Kukwera kwa mphamvu yamagetsi: Kukwera kwadzidzidzi kwa magetsi (nthawi zambiri kumachitika chifukwa cha mphezi kapena kusintha kwa gridi yamagetsi)
- Phokoso la mzere: Kusokoneza magetsi kosafunikira komwe kumasokoneza magwiridwe antchito a chipangizocho
Kodi chipangizo choteteza ku matenda a SPD (Surge Protective Device) n'chiyani?
SPD (Chida Choteteza Kukwera) ndi mtundu wapadera wa chitetezo cha ma surge chomwe chimapangidwira chitetezo chachikulu komanso cholimba—chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale, mabizinesi, komanso m'nyumba zofunika kwambiri. Chimagawidwa m'mitundu yosiyanasiyana (T1, T2, T3) kutengera malo ake oikira ndi mphamvu yogwiritsira ntchito ma surge current, kuonetsetsa kuti pali chitetezo cha magawo amagetsi kuyambira polowera mpaka kumapeto kwa zida.
Ma SPD amagwira ntchito pogwiritsa ntchito zinthu monga Metal Oxide Varistors (MOV) ndi Gas Discharge Tubes (GDT) kuti atenge kapena kusinthitsa mphamvu ya surge. Pamene voltage yapitirira malire otetezeka, zinthuzi zimagwira ntchito nthawi yomweyo, zomwe zimapangitsa kuti mphamvu yamagetsi yochulukirapo ifike pansi, motero zimateteza dera lalikulu ndi zida zolumikizidwa.
C&J Electrical's CJ-T1T2-AC SPD (Iimp: 12.5kA): Zinthu Zofunika & Ubwino
CJ-T1T2-AC series SPD ya C&J Electrical ndi njira yodzitetezera ku mafunde amphamvu kwambiri yopangidwira kuteteza zida zamagetsi otsika ku mphezi ndi kuwonongeka kwa mafunde. Mogwirizana ndi miyezo ya IEC61643-11 ndi GB/T 18802.11, ndi yoyenera PSD ya Gulu I+II (B+C class) m'makina osiyanasiyana opangira magetsi ndipo ikhoza kuyikidwa m'malo otetezedwa a LPZ0A-1 kapena apamwamba. Zinthu zake zazikulu ndi izi:
Zinthu Zofunika Kwambiri
- Kugwirizana kwa mawonekedwe awiri a mafunde: 10/350μs ndi 8/20μs spark mipata (imasintha malinga ndi mitundu yosiyanasiyana ya ma surge)
- Chomangira cholumikizira cha mtengo umodzi: Kukonza kosavuta komanso kusintha popanda kusokoneza magetsi
- Ukadaulo wa GDT wotsekedwa: Mphamvu yayikulu yozimitsa moto kuti igwire bwino ntchito yoyendetsa mafunde
- Chitetezo cha magetsi otsika kwambiri: Chimachepetsa mphamvu ya chipangizocho pakugwira ntchito bwino kwa chipangizocho
- Ma terminal awiri: Amathandizira kulumikizana kofanana kapena kotsatizana (kooneka ngati V) kuti kukhazikike mosavuta
- Kulumikizana kwa ntchito zambiri: Kugwirizana ndi ma conductor ndi mabasi
- Chizindikiro cha vuto looneka: Zenera lobiriwira limasanduka lofiira likawonongeka; malo osungira alamu akutali amapezeka kuti aziwunika nthawi yomweyo
- MOV yogwira ntchito kwambiri: Mphamvu yapamwamba kwambiri mpaka 12.5kA (10/350μs) kuti igwire bwino ntchito
Mafotokozedwe Aukadaulo
| Chizindikiro | Tsatanetsatane |
|---|---|
| Zosankha za chitsanzo | Mitundu ya T1T2 ndi T2 |
| Mulingo wamagetsi woteteza (Mmwamba) | 2.0kV |
| Nthawi yoyankha | ≤100ns (kusinthasintha kwa nthawi yomweyo) |
| Fuse yosungiramo zinthu zambiri | 200A gL/gG |
| Makonzedwe a pole | 1P, 2P, 3P, 4P (ngati mukufuna) |
| Kusintha kwa gawo | Ma module ochotsedwa kuti azisamalidwa mosavuta |
| Kukhazikitsa | Kuyika njanji ya 35mm (muyezo wa mapanelo amagetsi) |
Kutsatira Malamulo ndi Ziphaso
- Kukwaniritsa muyezo wapadziko lonse wa IEC61643-11
- Yovomerezedwa ndi CE satifiketi yachitetezo
- Yayesedwa mwamphamvu kuti ione ngati ndi yodalirika m'malo ovuta
Zochitika Zogwiritsidwa Ntchito Mosiyanasiyana
CJ-T1T2-AC SPD yapangidwa kuti igwiritsidwe ntchito kwambiri m'malo okhala, amalonda, ndi mafakitale, kuphatikizapo:
- Malo opangira mafakitaleMafakitale, malo opangira magetsi, malo opangira zinthu (chitetezo cha zida zopangira)
- Nyumba zamalonda: Malo ogulitsira zinthu, mahotela, nyumba zamaofesi, malo osungira deta (chitetezo cha HVAC, chitetezo, ndi makina a IT)
- Nyumba zokhalamoNyumba zazitali, nyumba zogona (zoteteza mphezi ndi mafunde amagetsi a nyumba)
- Zomangamanga zofunika kwambiriMalo olumikizirana mauthenga, zipatala, malo oyendera (amateteza zida zofunika kwambiri pantchito)
Njira zake zosinthira zoyika, mphamvu yolimba yogwiritsira ntchito mafunde amphamvu, komanso chizindikiro chodalirika cha zolakwika zimapangitsa kuti ikhale yoyenera kuyika zatsopano komanso zokonzanso.
N’chifukwa Chiyani Muyenera Kusankha CJ-T1T2-AC SPD ya C&J Electrical?
MuWoteteza Wokwera(SPD), mndandanda wa CJ-T1T2-AC wa C&J Electrical ndi wapadera chifukwa cha izi:
- Gulu la chitetezo chapawiriMtundu wa T1T2 umaphimba zosowa zonse zakunja ndi zamkati za chitetezo cha mafunde
- Mphamvu yayikulu yokwera: 12.5kA Kuyesa kwa Iimp kumatsimikizira chitetezo ku kukwera kwakukulu (monga mphezi)
- Kapangidwe kosavuta kugwiritsa ntchito: Ma module olumikizidwa, chizindikiro cha vuto lowoneka, ndi njira zolumikizira zosinthika
- Kutsatira malamulo padziko lonse lapansi: Chitsimikizo cha CE ndikutsatira miyezo yapadziko lonse lapansi zimatsimikiza kuti zinthu zikugwirizana komanso kuti zinthu zikuyenda bwino.
- Kuchita bwino kolimba: Ukadaulo wa GDT wotsekedwa komanso MOV yogwira ntchito bwino kuti ikhale yodalirika kwa nthawi yayitali
Kaya mukufunikira kuteteza zida zopangira mafakitale, makina omangira nyumba zamalonda, kapena zomangamanga zamagetsi m'nyumba, CJ-T1T2-AC SPD imapereka chitetezo chokwanira komanso chodalirika cha surge.
Lumikizanani nafe
Ngati muli ndi mafunso okhudza zomwe zafotokozedwa, tsatanetsatane waukadaulo, njira zosinthira, kapena maoda ambiri, chonde musazengereze kulankhulana ndi C&J Electrical. Gulu lathu la akatswiri ladzipereka kupereka njira zodzitetezera ku ma surge kuti zikwaniritse zosowa zanu.
