Amabhulokhi okusabalalisa amandla (PDB) omzila we-DIN
I-Weidmuller di-istribution blocks yezingxenye eziphambanayo zocingo ukusuka ku-1.5 mm² ukuya ku-185 mm² - Amabhulokhi anamandla okusabalalisa ahlangene oxhumo lwentambo ye-aluminium nentambo yethusi.
Izigaba zokusabalalisa (i-PDB) kanye namabhulokhi okusabalalisa kancane ukuze kube namandla okusabalalisa
Amabhulokhi okubamba kanye namabhulokhi okusabalalisa amandla (i-PDB) kaloliwe we-DIN alungele ukuqoqa nokusabalalisa amandla ngaphakathi kwamabhokisi okusabalalisa okungaphansi kanye ne-switchgear. Idizayini encane yamabhulokhi okubamba amandla inika amandla ukuminyana kwezintambo okucacile nokuphezulu. Amabhlogo wamandla aphephile ngomunwe kuzo zonke izinhlangothi ngokuhambisana ne-EN 50274 kanye nokumelana nesifunda esifushane ngokuhambisana nezinga eliphezulu le-SCCR (200 kA) futhi kuqinisekisa izinga eliphezulu lokuphepha.
Ngenxa yokugqoka okukhethekile komzimba wethusi, abaqhubi bezintambo zethusi, izintambo ze-aluminium kanye nama-flat conductors angaxhunywa ku-block yokusabalalisa kwesigaba. Izimvume ngokuya nge-VDE, UL, CSA kanye ne-IEC zivumela ukusetshenziswa kwezinye izinhlelo zokusebenza zezimboni nezimakethe zamazwe ngamazwe.
Ukuxhumana kwezintambo zethusi ne-aluminium
Umgogodla wethusi webhulokhi yokusabalalisa ne-coat yayo ekhethekile, ngokuhambisana nezikulufu ezine-hexagonal, yenza uxhumano lwezintambo zethusi ne-aluminium. Kokubili amadizayini ayindilinga nanjengomkhakha wamakhondatha angaxhunywa kubhulokhi yokusabalalisa amandla (i-PDB) kuloliwe we-DIN. Ukuxhumeka kwama-conductor ayisicaba nakho kungabonakala kwamanye amabhlogo wokusabalalisa okungenzeka.
Amabhulokhi okusabalalisa okungenzeka ahambisana namanye
Amabhulokhi okusabalalisa anamandla e-WPD (i-PDB) anokuxhumeka kwesikulufu angaxhunywa ngendlela eguquguqukayo futhi kalula ngebhuloho lethusi eliyisicaba. Ukuphindwa kabili noma ukuphindwa kathathu kwamaphoyinti okuxhumana ohlangothini oluphumayo kungafezeka. Ngale njongo, amabhlogo wetheminali yamandla angaxhunywa ndawonye ukuze kuzuzwe ukuqina okwengeziwe komshini kumzila wesitimela we-DIN.
Ibhulokhi yokusabalalisa ehlangene
Umklamo oyingqayizivele wezitebhisi uvumela usayizi omncane wamabhulokhi okusabalalisa okungenzeka we-WPD (PDB). Uma kuqhathaniswa nokusetha okuvamile, ukonga isikhala kutholwa ngaphandle kokulahlekelwa ukucaca ngaphakathi kwekhabhinethi.
Isibonelo, intambo eyodwa enesiphambano esilinganiselwe esingu-95 mm² kanye nezintambo ezine ezinesiqephu esilinganiselwe esingu-95 mm² ingaxhunywa kububanzi obungu-3.6 cm kuphela, nobuncane bobude buphelele obungamasentimitha ayisikhombisa.
Ukuhluka kwemibala yawo wonke amandla
Amabhulokhi wetheminali anombala ayatholakala ukuze kufakwe izintambo ezicacile kanye nokufakwa kwekhabhinethi ye-switchgear. Umbala oluhlaza okwesibhakabhaka njengebhulokhi yetheminali engu-N noluhlaza okotshani kubhulokhi yetheminali ye-PE (ephansi). Ngokuya ngebhulokhi yokusabalalisa amandla kanye nesicelo, izintambo zesigaba zingakhethwa phakathi kokubomvu, okumnyama, okunsundu nokumpunga.
