3. Txias: Tom qab tsim, cov conductors, thaum tseem kub, raug sib xyaw ua ke los ntawm cov txheej txheem txias sai kom cov khoom tawv thiab tswj nws cov duab.
Cov Txheej Txheem Rwb Thaiv Tsev
Thaum tus neeg xyuas hluav taws xob tau ua tiav lawm, kauj ruam tom ntej yog siv ib txheej rwb thaiv tsev. Cov txheej txheem no yog qhov tseem ceeb los tiv thaiv cov hluav taws xob kom tsis txhob khiav tawm ntawm lub cable thiab ua rau muaj kev luv luv. Cov txheej txheem rwb thaiv tsev muaj cov kauj ruam hauv qab no:
1. Kev Rho Tawm Rwb Thaiv Tsev: Txoj kev no zoo ib yam li cov txheej txheem rho tawm ntawm tus neeg xyuas pib. Cov khoom rwb thaiv tsev raug yaj thiab yuam los ntawm lub pwm khoob ncig lub neeg xyuas pib uas tsim, tsim ib txheej rwb thaiv tsev sib npaug thoob plaws tag nrho cov xov hlau.
2. Txheej Txheem Kho Kom Zoo: Qee hom insulators xav tau txheej txheem kho kom zoo kom ua tiav qhov muaj zog thiab yooj ywm tshaj plaws. Qhov no feem ntau ua tiav los ntawm kev siv lub qhov cub tshwj xeeb uas ua kom lub cable sov rau lub sijhawm tshwj xeeb.
Txheej Txheem Tiv Thaiv
Hauv qee qhov kev siv, tshwj xeeb tshaj yog cov uas cuam tshuam nrog kev xa cov teeb liab lossis hauv cov chaw uas muaj kev cuam tshuam hluav taws xob ntau (EMI), cov cables xav tau kev tiv thaiv. Kev tiv thaiv pab tiv thaiv cov teeb liab xa tawm los ntawm kev cuam tshuam sab nraud. Cov txheej txheem tiv thaiv suav nrog ntau txoj kev, xws li:
1. Txheej ntawv ci txhuas: Ntawv ci txhuas tuaj yeem qhwv ib ncig ntawm cov xov hlau uas muaj cov khoom rwb thaiv tsev kom muab kev tiv thaiv EMI. Txoj kev no feem ntau siv rau hauv cov xov hlau coaxial.
2. Kev Sib Txuas: Cov xov hlau kuj tseem tuaj yeem tiv thaiv tau siv cov xov hlau sib txuas ncig lub rwb thaiv tsev. Hom kev tiv thaiv no feem ntau yooj ywm dua thiab muab kev tiv thaiv zoo dua los ntawm kev cuam tshuam zaus siab.
Kev Ntsuas Zoo
Tom qab ua tiav tag nrho cov txheej txheem tsim khoom, cov xov hlau yuav tsum tau kuaj xyuas kom paub tseeb tias lawv qhov zoo thiab kev ua tau zoo ua tau raws li cov qauv uas tau teeb tsa. Kev kuaj xyuas zoo muaj ntau theem, suav nrog:
1. Kev Ntsuas Hluav Taws Xob: Cov xov hlau raug sim los ntsuas qhov tsis kam, capacitance, thiab inductance, kom ntseeg tau tias lawv cov kev ua haujlwm hluav taws xob ua tau raws li cov qauv tsim.
