Lub luag haujlwm tseem ceeb ntawm High-Voltage Fais Distribution Systems: Lub siab -voltage fais fab faib system nyob rau hauv prefabricated substation yog zoo li cov hlab ntsha hauv tib neeg lub cev, lub luag hauj lwm rau kev pib faib thiab kev tiv thaiv hluav taws xob hluav taws xob. Cov kev teeb tsa ib txwm muaj xws li lub nplhaib tseem ceeb lossis lub thawv cable, ua haujlwm SF6 rwb thaiv tsev lossis lub tshuab nqus tsev vacuum, uas yog qhov me me thiab muaj kev ntseeg siab. Lub kaw lus tuaj yeem ua tiav luv luv - Circuit Court breaking thiab overload tiv thaiv ntawm qhov voltage ntawm 10kV, nrog rau qib kev tiv thaiv feem ntau ncav cuag IP34 los yog siab dua, yoog rau qhov hnyav sab nraum zoov.
Kev hloov hluav taws xob hauv Transformer Systems: Transformers yog "lub siab" ntawm prefabricated substations. Tam sim no, qhuav-hom transformers lossis roj-immersed transformers yog lub ntsiab. Qhuav- hom transformers muaj qhov zoo ntawm kev saib xyuas-dawb thiab muaj hluav taws kub zoo, nrog lub peev xwm feem ntau yog li ntawm 315-2500kVA; roj-immersed transformers muaj ntau dua cov cua kub dissipation efficiency thiab yog haum rau loj{10}} muaj peev xwm daim ntaub ntawv. Tshiab amorphous alloy transformers tuaj yeem txo qhov tsis muaj qhov poob los ntawm 70% thiab tswj kev khiav hauj lwm suab nrov hauv qab 55 decibels, ua tiav kev txuag hluav taws xob ntsuab.
Kev Tswj Xyuas Kev Txawj Ntse ntawm Tsawg-Voltage Power Distribution Systems: Qhov qis-voltage fais fab faib system zoo li lub paj hlwb, lub luag haujlwm rau kev faib hluav taws xob zaum kawg. Niaj hnub nimno prefabricated substations feem ntau yog nruab nrog cov ntse qis -voltage switchgear, uas muaj cov haujlwm xws li kev saib xyuas tej thaj chaw deb thiab kev ntsuas hluav taws xob zoo. Lub kaw lus tau txais kev tsim qauv, suav nrog cov khoom xa tuaj, cov khoom them nyiaj, thiab cov khoom siv hluav taws xob, thiab tuaj yeem paub txog cov haujlwm zoo xws li kev them nyiaj rov qab siv hluav taws xob thiab kev tswj hwm kev sib raug zoo, txhim kho lub zog xa hluav taws xob mus rau ntau dua 95%.
