High-voltage cablesyog qhov tseem ceeb hauv cov tshuab X-ray.Koj puas paub cov qauv ntawm high-voltage cables?Niaj hnub no peb yuav tham luv luv txog lub luag haujlwm ntawm txheej semiconductor hauv high-voltage cables.
Lub semiconductor txheej nyob rau hauv lubhigh-voltage cableyog qhov peb feem ntau hu ua "shielding", uas yog qhov tseem ceeb ntawm kev ntsuas los txhim kho kev faib hluav taws xob.Tus neeg xyuas pib cable yog tsim los ntawm kev sib tw ntau cov xov hlau, thiab nws yog ib qho yooj yim los tsim cov cua sib txawv ntawm nws thiab cov txheej insulating.Tsis tas li ntawd, qhov saum npoo ntawm tus neeg xyuas pib tsis du, uas yuav ua rau hluav taws xob muaj zog.
Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ntxiv ib txheej shielding ntawm semiconducting khoom nyob rau saum npoo ntawm tus neeg xyuas pib, uas yog equipotential nrog shielded neeg xyuas pib thiab muaj kev sib cuag zoo nrog cov insulating txheej, thiaj li tsis txhob ib feem ntawm tus neeg xyuas pib thiab cov insulating txheej.Ntaub thaiv npog.
Tej zaum kuj yuav muaj qhov sib txawv ntawm qhov chaw insulating thiab cov sheath tiv tauj, uas yog qhov ua rau muaj qhov paug tawm ib nrab.Yog li ntawd, ib tug shielding txheej ntawm semiconducting khoom yog ntxiv rau saum npoo ntawm insulating txheej, uas muaj kev sib cuag zoo nrog lub shielded insulating txheej thiab yog nyob rau hauv zoo kev sib cuag nrog hlau shielding txheej.Lub tsho yog equipotential kom tsis txhob muaj ib feem tawm ntawm cov txheej insulating thiab lub tsho, thiab cov txheej no yog shielded raws li cov txheej shielding txheej.
Rau extruded insulated cables uas tsis muaj hlau sheaths, ntxiv rau ib tug semi-conductive shielding txheej, ib tug hlau shielding txheej qhwv nrog tooj liab daim kab xev los yog tooj liab hlau yuav tsum tau ntxiv.Kev ua haujlwm ntawm cov txheej txheem hlau thaiv no yog kom dhau lub peev xwm tam sim no thaum lub sijhawm ua haujlwm ib txwm;Thaum lub kaw lus Thaum ib qho luv luv tshwm sim, nws ua raws li cov channel rau luv luv-circuit tam sim no thiab tseem tiv thaiv hluav taws xob teb.
Yog hais tias cov txheej txheej semiconducting txheej thiab tooj liab thaiv tsis muaj nyob rau hauv lub cable, qhov muaj peev xwm ntawm rwb thaiv tsev tawg ntawm cov cores ntawm peb-core cable yog siab heev.Yog li ntawd, thaum yuav khoomhigh-voltage cables, nco ntsoov ua kom koj lub qhov muag qhib thiab yuav cov khoom muaj kev nyab xeeb thiab tsim nyog.
