Neutral Grounding Resistor tsis ua haujlwm ntawm nws tus kheej. Nws yuav tsum tau koom tes nrog ntau yam kev faib tawm, kev saib xyuas thiab kev tiv thaiv cov cuab yeej los tsim kom muaj kev tiv thaiv hauv av kom tiav siv rau cov nroj tsuag kev lag luam, cov tsev lag luam, kev faib hluav taws xob hauv nroog thiab cov chaw tsim hluav taws xob tshiab. Txhua lub cuab yeej sib txuam ua nws txoj haujlwm uas tau tsim thiab ua tiav Neutral Grounding Resistor kom xa cov kev tiv thaiv kab hluav taws xob dav dav. Cov cuab yeej sib txuam tseem ceeb thiab lawv cov txiaj ntsig kev sib koom tes tau piav qhia hauv qab no.
Fais fab transformers sawv cev rau cov khoom siv tseem ceeb tshaj plaws. Hom qhuav, roj-immersed thiab lub thawv-hom transformers tuaj yeem txuas Neutral Grounding Resistor rau lawv cov high-voltage lossis low-voltage nruab nrab cov ntsiab lus. Raws li cov tub ntxhais tseem ceeb rau kev hloov pauv hluav taws xob thiab kev xa hluav taws xob, cov khoom siv hluav taws xob muaj kev cuam tshuam rau ib theem ntawm lub ntiaj teb ua txhaum thiab peb-theem imbalance. Txuas nrog transformer nruab nrab cov ntsiab lus, Neutral Grounding Resistor txwv tsis pub luv luv tam sim no, tiv thaiv winding rwb thaiv tsev los ntawm kev tawg thiab burnout, stabilizes nruab nrab-point muaj peev xwm thiab tiv thaiv voltage offset thiab muaj peev xwm drift.
High-voltage switchgears, low-voltage tis txee thiab lub nplhaib tseem ceeb yog lwm cov koom tes tseem ceeb. Switchgears lees paub lub zog faib hluav taws xob, hloov hluav taws xob hloov hluav taws xob thiab kev sib cais tsis raug raws li hubs ntawm lub zog faib hluav taws xob. Nruab nrab Grounding Resistor txuas nrog lub voj voog nruab nrab ntawm sab hauv lossis sab nraud. Thaum cov hluav taws xob tawm mus raug kev ua txhaum hauv lub ntiaj teb, Neutral Grounding Resistor txwv tam sim no thiab txo lub zog arc. Nws tiv thaiv kev raug mob hnyav xws li hauv lub voj voog luv luv thiab busbar burnout, thiab ua haujlwm nrog switchgear breaking functions kom cais cov faulty circuits thaum tswj fais fab mov rau seem ntawm daim phiaj.
Cov khoom siv tsis raug saib xyuas feem ntau suav nrog xoom-ib theem tam sim no transformers thiab xoom-sequence voltage transformers. Neutral Grounding Resistor hloov kho qhov tsis raug tam sim no thiab qhov ntsuas hluav taws xob thaum ua haujlwm. Transformers sau cov ntaub ntawv xoom-ib ntu ntawm lub sijhawm tiag tiag thiab ntes cov cim hauv ntiaj teb. Yog tsis muaj xws li transformers, Neutral Grounding Resistor tsuas tuaj yeem muab kev txwv tsis pub dhau tam sim no, thiab tsis tuaj yeem txhawb qhov chaw ua txhaum lossis kev pom zoo. Cov cim sau tau raug xa mus rau cov chaw rov qab kawg thiab muab cov ntaub ntawv raug siv rau kev txiav txim txhaum cai thiab kev saib xyuas, ua rau kev tiv thaiv hauv av ntau meej thiab tswj tau.
Kev tiv thaiv ntse thiab saib xyuas kho vajtse suav nrog cov khoom siv tiv thaiv microcomputer, cov kaw lus tsis raug, kev saib xyuas lub zog rov qab thiab cov cuab yeej ntse ntsuas-tswj. Txais tam sim no thiab voltage signals los ntawm transformers, microcomputer comprehensive tiv thaiv pab kiag li lawm txheeb xyuas pawg thiab qhov chaw nyob rau hauv ua ke nrog nrog rau tam sim no-limiting kev ua tau zoo ntawm Neutral Grounding Resistor, thiab qhib lub tswb los yog ncua sij hawm tripping kom muaj txhaum expansion. Fault recorders sau tam sim no, voltage thiab resistor xwm txheej ntawm lub sij hawm tsis ua hauj lwm thiab muab cov ntaub ntawv rau kev ntsuam xyuas txhaum thiab qhov system optimization. Lub tshuab hluav taws xob saib xyuas lub zog txhawb cov chaw taws teeb saib xyuas lub sijhawm tiag tiag thiab kev ua haujlwm ntse thiab kev saib xyuas tsis muaj neeg saib xyuas.
Nyob rau hauv cov xwm txheej tshiab-zog, Neutral Grounding Resistor feem ntau txuam nrog inverters, box-type transformers thiab combiner txee rau photovoltaic thiab wind-power tiam systems. Nws hais txog cov teeb meem tseem ceeb suav nrog kev sib txuam sib txawv, kev hloov pauv hluav taws xob thiab kev ua txhaum hauv ntiaj teb hauv cov phiaj xwm tshiab. Rau cov chaw muaj kev pheej hmoo siab, nws tseem tuaj yeem ua haujlwm nrog cov khoom siv hluav taws xob tiv thaiv hauv av thiab cov cuab yeej tshem tawm zoo li qub kom ua tiav ntau txheej tiv thaiv xob laim, hluav taws xob zoo li qub thiab lub ntiaj teb ua txhaum, thiab hloov mus rau cov kev xav tau sib txawv ntawm cov khoom siv hluav taws xob sib txawv ntawm cov ntawv thov sib txawv.
