Qhov uas yuav tsum muaj rau ntau yam hauv cov txee hluav taws xob
Qhov chaw deb ntawm ntau qhov chaw yog qhov tseem ceeb hauv cov khoom siv hluav taws xob, tab sis kuj tseem muaj kev nyab xeeb ntawm cov khoom siv hluav taws xob, tsis txhob muaj cov kev sib tw hluav taws xob tsis zoo Hauv qab no yuav muab cov lus qhia ntxaws ntxaws raws cov qauv thiab cov specifications .
Hluav taws xob clearance thiab nkag mus deb
(1) Kev tshem tawm hluav taws xob
Kev tshem tawm hluav taws xob ntshiab hais txog qhov luv tshaj plaws-kab deb tshaj plaws ntawm cov huab cua, feem ntau yog ua haujlwm qis dua ntawm cov cua (AC voltage tsis tshaj 1000v, DC voltage tsis pub tshaj 1500v), nyob rau ib puag ncig nrog kev ua qias tuaj ntawm 2 (feem ntau tsuas yog tsis ua cov pa phem, qee zaum ua rau muaj kuab paug tsis zoo vim yog hws):
Qhov tsawg kawg nkaus uas yuav tsum tau ua rau hluav taws xob tshem tawm yog 0.5 hli thaum cov ntsuas ntsuas hluav taws xob voltage yog qis dua 60v;
Qhov ntsuas rated voltage yog nruab nrab ntawm 60-300 v, thiab qhov kev yuav tsum muaj hluav taws xob tsawg kawg yog 3.0mm;
Qhov ntsuas rated voltage yog nruab nrab ntawm 300-690 v, thiab qhov kev xav tau hluav taws xob tsawg kawg yog 5.0mm;
Qhov ntsuas rated voltage yog nruab nrab ntawm 690-1000 v, thiab qhov kev xav tau hluav taws xob tsawg kawg yog 8}}} 0mm.
Yog tias qib muaj kuab paug ntawm ib puag ncig uas cov hluav taws xob hluav taws xob nyob twj ywm ua rau muaj kuab paug 3, lossis qhuav tsis muaj kuab lom yuav tseem yuav ua rau kev siv hluav taws xob tseem yuav nce raws li.
(2) Cropage nrug
Creepage nyob deb li cas hais txog qhov deb tshaj plaws ntawm ob qho kev sib txawv, noo noo, thiab lwm yam khoom siv voltication, thiab lwm yam khoom siv voltication nrog cov txheeb ze cov khoom siv tsis zoo. 175-250):
Qhov tsawg kawg nkaus yuav tsum tau ua rau kev ncua deb yog 0.6mm thaum cov ntsuas ntsuas hluav taws xob voltage yog qis dua 60v;
Qhov ntsuas rated voltage yog nruab nrab ntawm 60-300 v, thiab qhov tsawg tshaj plaws yuav tsum muaj rau kev ncua deb yog 3.2mm;
Qhov ntsuas rated voltage yog nruab nrab ntawm 300-690 v, thiab qhov yuav tsum tau ua rau cov neeg nkag mus deb yog 5.6mm;
Qhov ntsuas rated voltage yog nruab nrab ntawm 690-1000 v, thiab qhov yuav tsum tau ua rau cov neeg nkag mus deb yog 8 {}} 0mm.
Thaum cov pa paug nyob rau theem, cov ntaub ntawv siv, thiab lwm yam kev hloov pauv, tus nqi ntawm kev hloov pauv deb kuj tseem xav tau hloov kho raws li tus qauv .
