Cable Symmetry Design
Rau cov cables tshwj xeeb uas tsim los rau 1.8 / 3KW thiab qis dua qhov sib txawv zaus motors, symmetrical 3+1 cores thiab 4 core cables tsuas yog siv los ua cov khoom siv cables rau lub zog loj, tab sis cov qauv siv hluav taws xob zoo dua. Cables nruab nrab ntawm lub inverter thiab lub cev muaj zog zaus yuav tsum tau siv ib tug symmetrical cable qauv. Symmetrical cable qauv muaj xws li 3-core thiab 3+3-core hom. Lub 3+3-core cable qauv decomposes plaub cores (nruab nrab tub ntxhais) ntawm plaub-core insulated hlau (peb loj thiab ib tug me me) rau hauv peb me me insulated cores, symmetrically cabled. Rau 6/10kV sib txawv zaus lub cev muaj zog cables, cov qauv kab no txawv ntawm 6/10kV fais fab cables. Cov kab hluav taws xob zoo tib yam siv tooj liab daim kab xev tiv thaiv rau peb lub insulated cores ua ntej tsim cable, thaum lub zog sib txawv ntawm lub cev muaj zog siv tooj liab hlau thiab tooj liab daim kab xev tiv thaiv, extruded nrog theem - cais sheaths, thiab ces symmetrically cabled. Vim muaj kev sib hloov ntawm cov conductors, symmetrical cable cov qauv muab cov electromagnetic compatibility zoo dua, ua si lub luag hauj lwm hauv suppressing electromagnetic cuam tshuam, tshem tawm khib zaus nyob rau hauv siab harmonics, kev txhim kho lub anti-interference muaj peev xwm ntawm kuj sib txawv zaus lub cev muaj zog cables, thiab txo electromagnetic hluav taws xob nyob rau hauv tag nrho cov system.
Shielding Structure Design
Kev tiv thaiv ntawm 1.8 / 3kV thiab qis dua qhov sib txawv zaus lub cev muaj zog cables feem ntau lees txais kev tiv thaiv tag nrho . 6/10kV hloov pauv zaus lub cev muaj zog cables muaj cov theem- tshwj xeeb tiv thaiv thiab thaiv tag nrho. Theem- kev tiv thaiv tshwj xeeb feem ntau tuaj yeem siv tooj liab daim kab xev tiv thaiv lossis kev sib txuas ntawm tooj liab hlau thiab tooj liab daim kab xev thaiv. Cov qauv kev tiv thaiv tag nrho tuaj yeem siv kev sib xyaw ntawm tooj liab hlau thiab tooj liab daim kab xev tiv thaiv, tooj liab hlau braided shielding, tooj liab daim kab xev shielding, tooj liab hlau braided tooj liab daim kab xev shielding, thiab lwm yam., nrog lub shielding txheej cross-section thiab lub ntsiab conductor cross-section nyob rau hauv ib tug tej yam ratio. Cov qauv tiv thaiv kab hluav taws xob no tuaj yeem tiv thaiv electromagnetic induction, tsis zoo hauv av, thiab cov kab hluav taws xob tau cuam tshuam, txo inductance, thiab tiv thaiv kev quab yuam electromotive ntau dhau. Cov txheej thaiv thaiv tsis yog tsuas yog suppresses electromagnetic yoj emissions tab sis kuj ua haujlwm raws li txoj hauv kev luv luv -circuit tam sim no, tiv thaiv tus neeg xyuas pib nruab nrab. Rau 6/10kV sib txawv zaus lub cev muaj zog cables, txiav txim siab tias cov cable feem ntau raug rau radial rog thaum siv, galvanized steel daim kab xev tus pin txheej yog ntxiv sab nraum lub cable shielding txheej (nrog rau lub tes tsho cais ntxiv ntawm cov shielding txheej thiab steel daim kab xev pin txheej). Steel daim kab xev armor feem ntau ua hauj lwm raws li lub radial mechanical tiv thaiv txheej ntawm lub cable, thaum tseem muab ntxiv tag nrho shielding. Tshwj xeeb, kev siv ob yam khoom siv tiv thaiv kev sib txawv{19}} cov ntaub nplaum hlau thiab tooj liab hlau / daim kab xev shielding - ua kom muaj txiaj ntsig zoo hauv electromagnetic yoj tiv thaiv, ua rau muaj kev tiv thaiv zoo dua.
Cable Hluav taws xob Performance Design
Kev ua haujlwm hluav taws xob ntawm 1.8 / 3kV thiab qis dua qhov sib txawv ntawm lub cev muaj zog cables yog tsim raws li GB / T 12706.2002 tus qauv. 6/10kV hloov pauv zaus lub cev muaj zog cables, ntxiv rau ua tau raws li GB / T 12706.2002 tus qauv, muaj cov kev xav tau ntxiv rau kev ua haujlwm thiab inductance. Raws li kev siv tiag tiag ntawm cov kab hluav taws xob sib txawv thiab xa mus rau GB / T 12706.2002 thiab ABB cov kev qhia tshwj xeeb rau cov hluav taws xob xa hluav taws xob, cov hluav taws xob ua haujlwm tsis zoo ntawm cov cables tau txiav txim siab.
