Amabhulokhi okusabalalisa amandla (PDB) ezitimeleni ze-DIN
Weidmuller damabhlogo okusabalalisa izingxenye zezintambo kusukela ku-1.5 mm² kuya ku-185 mm² - Amabhlogo okusabalalisa amandla amancane okuxhuma ucingo lwe-aluminium kanye nocingo lwethusi.
Amabhulokhi okusabalalisa isigaba (PDB) kanye namabhulokhi okusabalalisa angaphansi ukuze kusatshalaliswe okungenzeka
Amabhulokhi okubopha kanye namabhulokhi okusabalalisa amandla (PDB) e-DIN rail afanele ukuqoqa nokusabalalisa amandla ngaphakathi kwamabhokisi okusabalalisa amancane kanye ne-switchgear. Umklamo omncane wamabhulokhi okubopha amandla wenza kube nokuxinana kwezintambo okucacile nokuphezulu. Amabhulokhi kagesi aphephile kuzo zonke izinhlangothi ngokuhambisana ne-EN 50274 kanye nokumelana kwe-short-circuit ngokuhambisana nezinga eliphezulu le-SCCR (200 kA) futhi kuqinisekisa izinga eliphezulu lokuphepha.
Ngenxa yokwembozwa okukhethekile komzimba wethusi, ama-conductor e-copper wire, izintambo ze-aluminium kanye nama-conductor asicaba angaxhunywa ku-phase distribution block. Ukuvunyelwa ngokwe-VDE, i-UL, i-CSA kanye ne-IEC kwenza kube lula ukusetshenziswa kwezinye izinhlelo zokusebenza zezimboni kanye nezimakethe zomhlaba wonke.
Ukuxhumeka kwezintambo zethusi ne-aluminium
Ingaphakathi lethusi lebhulokhi lokusabalalisa elinesimbozo salo esikhethekile, lihlanganiswe nezikulufo ezinezinhlangothi eziyisithupha, livumela ukuxhumeka kwezintambo zethusi neze-aluminium. Zombili imiklamo ye-conductor eyindilinga neyobunjwa njengomkhakha ingaxhunywa kubhulokhi lokusabalalisa amandla (PDB) ku-DIN rail. Ukuxhumeka kwe-flat conductors kungabonakala nakwamanye amabhulokhi okusabalalisa angaba khona.
Amabhulokhi okusabalalisa angaba khona phakathi komunye nomunye
Amabhulokhi okusabalalisa amandla e-WPD (PDB) anokuxhumeka kwezikulufo angaxhunywa ngokuguquguqukayo nangokulula ngebhuloho lethusi eliyisicaba. Ngakho-ke, amaphuzu okuxhuma aphindwe kabili noma aphindwe kathathu ohlangothini oluphumayo angatholakala. Ngale njongo, amabhulokhi e-power terminal angaxhunywa ndawonye ukuze kufezwe ukuzinza okwengeziwe kwemishini ku-DIN rail.
Ibhulokhi yokusabalalisa encane
Umklamo wezitebhisi oyingqayizivele uvumela usayizi omncane wamabhulokhi okusabalalisa amandla e-WPD (PDB). Uma kuqhathaniswa nokusetha okuvamile, ukonga isikhala kutholakala ngaphandle kokulahlekelwa ukucaca ngaphakathi kwekhabhinethi.
Isibonelo, ucingo olulodwa olunesigaba esilinganiselwe esingu-95 mm² kanye nezintambo ezine ezinesigaba esilinganiselwe esingu-95 mm² lungaxhunywa ngobubanzi obungu-3.6 cm kuphela, okungenani ukuphakama okuphelele kube amasentimitha ayisikhombisa.
Izinguquko zombala kuzo zonke izinto ezingaba khona
Amabhulokhi e-terminal anemibala ayatholakala ukuze kufakwe izintambo ezicacile kanye nokufakwa kwekhabhinethi ye-switchgear. Umbala oluhlaza okwesibhakabhaka njengebhulokhi ye-terminal ye-N kanye nohlaza okwebhulokhi ye-terminal ye-PE (ephansi). Kuye ngebhulokhi yokusabalalisa amandla kanye nohlelo lokusebenza, izintambo zesigaba zingakhethwa phakathi kobomvu, omnyama, onsundu kanye nompunga.
