Ua ntej, ib txwm tam sim no: ua ntej peb yuav tsum paub, nyob rau hauv kev siv ntawm lub Circuit Court los ntawm qhov loj ntawm lub fuse tam sim no. Nquag, peb yuav tsum tau teeb tsa tus nqi txo ua ntej, thiab tom qab ntawd xaiv raws li lub hauv paus ntsiab lus ntawm" tam sim no ib txwm yuav tsum tsawg dua cov khoom ntawm cov ntsuas tam sim no thiab txo cov coefficient".
Thib ob, fusing tam sim no: raws li UL specifications, fuses (fuses) yuav tsum tau fused sai sai nyob rau hauv cov xwm txheej ntawm 2 zaug ntawm rated tam sim no. Feem ntau, txawm li cas los xij, txhawm rau txhawm rau txhim khu kev sib txuas, nws raug pom zoo tias qhov fusing tam sim no ntau dua 2.5 npaug ntawm qhov ntsuas tam sim no. Tsis tas li ntawd, yog tias lub sijhawm fusing tseem ceeb, koj yuav tsum xa mus rau lub fusing yam ntxwv daim duab muab los ntawm cov chaw tsim khoom los txiav txim siab.
Thib peb, luv luv Circuit Court tam sim no: peb muab qhov luv luv Circuit Court thaum qhov ntws ntawm qhov siab tshaj plaws tam sim no hu ua luv Circuit Court tam sim no. Rau txhua yam ntawm fuse, lub peev xwm tawg tau raug teev tseg, peb yuav tsum tau saib xyuas kom tsis txhob ua kom luv luv tam sim no tshaj qhov muaj peev xwm tawg thaum xaiv lub fuse. Yog tias xaiv lub fuse nrog lub peev xwm qhib me me, nws tuaj yeem tshuab lub fuse lossis ua rau hluav taws.
Plaub, impulse tam sim no: soj ntsuam lub waveform ntawm impulse tam sim no (mem tes tam sim no waveform), nrog I2t tus nqi (joule integral tus nqi) los xam nws lub zog. Qhov cuam tshuam ntawm kev poob siab tam sim no ntawm fuse kuj txawv vim nws qhov sib txawv thiab ntau zaus. Qhov piv ntawm I2t tus nqi ntawm impulse tam sim no rau tus nqi I2t ntawm monopulse fuse txiav txim seb tus naj npawb ntawm impulse tam sim no tsis kam ntawm lub fuse.
Thib tsib, qhib Circuit Court voltage: qhib Circuit Court voltage feem ntau yuav tsum tau xaiv tsawg tshaj li qhov ntsuas voltage. Piv txwv li, fuse ntsuas DC24V tuaj yeem tawg lossis tawg thaum siv hauv AC100V Circuit Court
