Qhov kub thiab txias: -5 ℃ ~ + 40 ℃, tus nqi nruab nrab hauv 24 teev tsis pub tshaj + 35 ℃, thiab tus nqi nruab nrab hauv ib xyoos yuav tsum tsawg dua tus nqi no. Qhov siab ntawm qhov chaw teeb tsa tsis pub tshaj 2000m
Huab cua zoo: Huab cua huv, thiab nws cov av noo tsis pub tshaj 50% thaum qhov kub thiab txias yog 40 ℃. Nws raug tso cai kom muaj av noo siab ntawm qhov kub thiab txias qis, piv txwv li, cov av noo tuaj yeem ncav cuag 90% thaum 20 ℃, thiab nws yuav tsum xav txog qhov dej noo uas tsim tawm ntawm qhov chaw ntawm cov khoom uas yog vim qhov kub thiab txias sib txawv.
Qhov Hluav Taws Xob Tus nqi siab tshaj plaws ntawm qhov hluav taws xob ntawm lub cev tsis pub tshaj 110% ntawm qhov hluav taws xob ntsuas ntawm lub fuse.
Pawg kev teeb tsa: III
Qib ntawm kev ua qias tuaj: tsis tsawg dua 3
Txoj hauj lwm teeb tsa Cov koob fuse no tuaj yeem ntsia tau ntsug, kab rov tav, lossis obliquely ntawm cov sijhawm ua haujlwm yam tsis muaj kev co pom tseeb, lossis kev cuam tshuam kev co.
Lus Cim: yog tias lub fuse siv rau hauv qhov sib txawv ntawm qhov kev teeb tsa ib txwm muaj, nws yuav tsum tau sib tham nrog cov chaw tsim khoom.

Cov yam ntxwv ntawm cov qauv Cov koob fuse no muaj cov fuse txuas, lub fuse tuav (fuse puag, fusion loading Cheebtsam). Fuse txuas muaj fuse raj, yaj thiab filler. Cov seem sib txawv yaj ntawm cov siv tooj liab ntshiab lossis hlau yog kaw rau hauv lub raj fuse muaj zog siab, muaj puv rau hauv lub raj fuse nrog cov xuab zeb quartz ntshiab uas tau ua tiav los ntawm tshuaj lom neeg ua cov khoom siv arcing. Ob qhov kawg ntawm cov yaj yog qhov chaw welded kom ruaj khov hluav taws xob txuas nrog lub phaj kawg (lossis phaj txuas), uas tsim lub hau cylindrical fuse. Fuse tuav yog muaj lub hauv paus fuse thiab fusion loading Cheebtsam, nws zoo li tag nrho cov qauv sealing thaum fuse ua haujlwm. Muaj peev xwm nrog lub teeb qhia fusing ntawm lub fusion loading Cheebtsam, lub teeb qhia yuav teeb thaum lub fuse txuas fuses los ceeb toom tus neeg teb xov tooj. Lub tuav yog ntsia los ntawm TH35 tus qauv tsheb ciav hlau, yooj yim thiab yooj yim. Lub davhlau ya nyob twg ntawm ob qhov kawg yog txuas nrog cov hlau sab nraud los ntawm lub hau ntswj.
