Ma block ogawa magetsi (PDB) a njanji za DIN
Weidmuller dMa block ogawa ma waya kuyambira 1.5 mm² mpaka 185 mm² - Ma block ogawa ang'onoang'ono olumikizira waya wa aluminiyamu ndi waya wamkuwa.
Magawo ogawa magawo (PDB) ndi magawo ogawa magawo kuti agawidwe mosavuta
Ma block omangirira ndi ma power distribution blocks (PDB) a DIN rail ndi oyenera kusonkhanitsa ndi kugawa ma potentials mkati mwa mabokosi ogawa ndi switchgear. Kapangidwe kakang'ono ka ma power clamping blocks kamalola kuti mawaya azikhala omveka bwino komanso okwera. Ma power blocks ndi otetezeka mbali zonse motsatira EN 50274 ndipo kukana kwa short-circuit motsatira muyezo wapamwamba wa SCCR (200 kA) kumatsimikiziranso chitetezo chapamwamba.
Chifukwa cha utoto wapadera wa thupi la mkuwa, mawaya a aluminiyamu ndi mawaya athyathyathya amatha kulumikizidwa mu gawo logawa magetsi. Kuvomerezedwa malinga ndi VDE, UL, CSA ndi IEC kumathandiza kuti zigwiritsidwe ntchito m'mafakitale ena komanso m'misika yapadziko lonse.
Kulumikiza kwa waya zamkuwa ndi aluminiyamu
Pakatikati pa chipolopolo chogawa ndi utoto wake wapadera, pamodzi ndi zomangira za hexagonal, zimathandiza kulumikizana kwa mawaya amkuwa ndi aluminiyamu. Mapangidwe onse ozungulira komanso ofanana ndi gawo amatha kulumikizidwa mu chipolopolo chogawa mphamvu (PDB) pa njanji ya DIN. Kulumikizana kwa ma conductors athyathyathya kumatha kuchitikanso m'machipolopolo ena omwe angathe kugawa.
Mizere yogawa yomwe ingakhalepo pakati pa milatho
Ma WPD potential distribution blocks (PDB) okhala ndi screw connection amatha kulumikizidwa mosavuta komanso mosavuta kudzera mu mlatho wathyathyathya wamkuwa. Kuwirikiza kawiri kapena katatu kwa malo olumikizira mbali yotuluka kumatha kuchitika. Pachifukwa ichi, ma power terminal blocks amatha kulumikizidwa pamodzi kuti pakhale kukhazikika kwa makina pa DIN rail.
Chipika chogawa chaching'ono
Kapangidwe ka masitepe kapadera kamalola kukula kochepa kwa ma WPD potential distribution blocks (PDB). Poyerekeza ndi makonzedwe achikhalidwe, kusunga malo kumachitika popanda kutaya kumveka bwino mkati mwa kabati.
Mwachitsanzo, waya umodzi wokhala ndi gawo lopingasa la 95 mm² kuphatikiza mawaya anayi okhala ndi gawo lopingasa la 95 mm² akhoza kulumikizidwa m'lifupi mwa 3.6 cm yokha, ndi kutalika kosachepera masentimita asanu ndi awiri.
Mitundu yosiyanasiyana ya mitundu pa chilichonse chomwe chingatheke
Ma terminal blocks okhala ndi mitundu yosiyanasiyana amapezeka kuti azitha kulumikiza mawaya bwino komanso kuyika kabati ya switchgear. Mtundu wabuluu ngati N terminal block ndi wobiriwira wa PE (ground) terminal block. Kutengera ndi power distribution block ndi ntchito, phase wiring ingasankhidwe pakati pa ofiira, akuda, abulauni ndi a imvi.
