Isikhokelo soKhetho lweeBloko zeSitimela se-DIN Rail: Uvavanyo lwangoku, izixhobo, kunye neMigangatho yokuFaka
TL;DR
- Khetha iibhloko zesiphelo sendlela ye-DIN ngokuthelekisa umbane olinganisiweyo (24A ukuya kwi-232A) nomthwalo wesekethe yakho, kunye necandelo elinqamlezileyo lomqhubi njengothintelo oluphambili lomzimba.
- I-PA66 ene-V-0 yokutsha yeyona nto ikhethwayo kwiikhabhathi zolawulo lwemizi-mveliso, esebenza ngokuthembekileyo ukusuka kwi--40C ukuya kwi-+120C.
- I-TS35 (35x7.5mm) ngokwe-EN 60715 yiprofayili eqhelekileyo yokuxhoma; qinisekisa uhlobo lwereli kunye nobukhulu bezinto (1.0±0.1mm) ngaphambi kokuba u-odole.
- I-UL 1059 yaseMntla Melika kunye ne-CE/IEC 60947-7-1 kwimarike ye-EU zezona ziqinisekiso ziphantsi ekufuneka zithwalwe yi-terminal block yakho.
- Iintlobo ze-spring-clamp zinciphisa ixesha lokufakela malunga ne-40% xa kuthelekiswa neebhloko ze-screw, nto leyo eyenza ukuba zisebenzise imali eninzi iiphaneli zolawulo ezinoxinano oluphezulu.
Ukukhetha ibhloko yesitishi se-DIN esifanelekileyo kwiphaneli yokulawula yemizi-mveliso kufuna ukuthelekisa iiparameter ezintathu: umlinganiselo wangoku kufuneka udlule umthwalo omkhulu wesekethe ubuncinane nge-20%, izinto zokuhlala kufuneka zimelane nemeko yokusebenza, kwaye iprofayili yokuxhoma kufuneka ihambelane nemigangatho ye-EN 60715. Esi sikhokelo sihamba kuzo zonke iinkcukacha ngedatha enokubalwa kunye namanqaku esicelo sokwenyani.
Kwiminyaka engaphezu kweshumi yokwenziwa kweebhloko zesiphelo see-OEMs kulo lonke elaseMntla Melika, eYurophu, naseMzantsi-mpuma Asia, sibone iimpazamo ezifanayo zokukhetha ziphindaphindwa - iibhloko ezinkulu kakhulu zemiqondiso yamandla aphantsi, iireli ezincinci kakhulu zeebhloko ezinzima ezinamanqanaba amaninzi, kunye nokungafani kwezinto ezikhokelela ekusileleni kwentsimi. Esi sikhokelo sikhona ukuze sisuse ezo mpazamo.
Zithini iiRatings zangoku zeDIN Rail Terminal Blocks?
Izilinganiso zangoku zebhloko yesiphelo sesitimela se-DIN ziqala kwi-24A kwiibhloko eziqhelekileyo ze-2.5mm2 ukuya kuthi ga kwi-232A kwiibhloko zamandla ze-95mm2 ezinzima, njengoko kuchaziwe yimigangatho ye-IEC 60947-7-1 kunye ne-UL 1059.
Ibhloko nganye yesiphelo inezilinganiso ezimbini zamandla ombane: umsinga osebenzayo olinganisiweyo (Ie) ngokwe-IEC 60947-7-1 kunye nomsinga olinganisiweyo we-UL. Zihlala zifana — kodwa azisoloko zifana. Umsinga wokwenyani ibhloko enokuwuthwala uxhomekeke kwicandelo elinqumlayo le-conductor, ubushushu be-ambient, kunye nokuba ibhloko ifakwe kwisimo esinye okanye esihlanganisiweyo.
