Dab tsi yog cov haujlwm ntawm high-voltage capacitor them nyiaj txee?

Vim li cas thiaj li yuav tsum tau them nyiaj capacitance? Vim li cas thiaj siv cov nyiaj capacitance es tsis txhob tiv thaiv lossis kev them nyiaj inductance? Qhov no yog vim hais tias thaum lub zog AC nkag mus rau hauv cov khoom siv hluav taws xob, nws qhov tam sim no thiab qhov hluav taws xob yog synchronized vim hais tias cov load resistive tsis muaj reactive zog. Txawm li cas los xij, thaum AC fais fab nkag mus rau hauv qhov inductive load, qhov cuam tshuam ntawm inductance yuav ua rau theem voltage ntawm AC zog mus rau theem tam sim no. Ib yam li ntawd, thaum AC fais fab nkag mus rau hauv lub peev xwm thauj khoom, cov theem tam sim no ntawm AC lub zog yuav nce qib voltage vim qhov cuam tshuam ntawm capacitance. Hauv cov khoom siv hluav taws xob niaj hnub, feem ntau ntawm lawv yog cov khoom tiv thaiv thiab inductive loads. Resistive loads tsis xav tau lub zog reactive, yog li tsis tas yuav muaj kev them nyiaj hluav taws xob. Txawm li cas los xij, cov khoom siv inductive xav tau lub zog reactive, uas tuaj yeem ua rau theem hluav taws xob thiab theem tam sim no tsis sib xws, ua rau muaj hluav taws xob ua rau tam sim no. Yog li txhawm rau synchronize cov theem tam sim no thiab voltage, nws yog ib qho tsim nyog yuav tsum tau mus rau qhov sib npaug ntawm cov capacitors ntawm qhov inductive load. Vim hais tias inductive loads ua rau voltage coj tam sim no, thiab capacitive loads ua rau tam sim no rau lead voltage, lawv yog zoo thiab tsis zoo, tsuas yog offsetting ib leeg. Yuav them li cas? Niaj hnub no, reactive fais fab them nyiaj controllers feem ntau yog siv los ua kom tiav tag nrho cov nyiaj tsis siv neeg.

Lub reactive fais fab controllers Ua, Ub, thiab Uc yog feem ntau txuas nrog peb-theem nyob hlau, uas muaj peev xwm muab voltage signals rau lub reactive fais fab maub los; Peb lub transformers tam sim no txuas nrog lub hnub qub, thiab lwm qhov kawg yog txuas nrog Ia, Ib, thiab Ic terminals ntawm reactive fais fab maub los, uas tuaj yeem muab cov teeb liab tam sim no rau tus tswj fais fab reactive. Tom qab lub reactive fais fab maub los muaj tam sim no thiab voltage signals, nws muaj peev xwm ntsuas lub hwj chim yam tseem ceeb thiab tswj lub coil energization thiab disconnection ntawm 8 contactors. Thaum lub reactive fais fab maub los kuaj pom tias lub zog ntawm cov kab qis dhau lawm, nws yuav cia li txuas lub contactor coil. Nyob rau hauv txoj kev no, lub txhab nyiaj capacitor txuas nrog lub ntsiab kev sib cuag ntawm tus contactor yog txuas nrog nyob rau hauv parallel mus rau lub busbar, thiab lub hwj chim yuav nce. Yog hais tias lub hwj chim yam tsis txaus, lub reactive fais fab maub los yuav txuas mus rau ib co coil thiab txuas ib pab pawg neeg ntawm capacitors nyob rau hauv parallel mus txog rau thaum lub hwj chim factor mus txog qhov teeb meem. Thaum lub reactive fais fab maub los kuaj pom tias lub hwj chim ntawm kab yog siab dhau lawm, nws yuav txiav tawm ib txheej ntawm capacitors. Vim yog qhov hloov pauv dynamic hauv kev thauj khoom hauv kab, reactive fais fab nyiaj them kuj tseem dynamic.

Lub luag haujlwm ntawm reactive fais fab nyiaj them yog dab tsi? Lub luag haujlwm tseem ceeb ntawm kev them nyiaj rov qab siv hluav taws xob yog txhawm rau txhim kho lub zog, thiab lub hom phiaj tseem ceeb ntawm kev txhim kho lub zog hluav taws xob yog txhawm rau txhim kho kev siv hluav taws xob thiab txo qis zog. Yog tias lub zog tso zis ntawm tib lub zog hluav taws xob (transformer) yog tag nrho lub zog ua haujlwm, nws tuaj yeem hloov pauv mus rau hauv cov txiaj ntsig kev lag luam, vim tias lub tuam txhab muab hluav taws xob them nqi raws li lub zog nquag. Yog hais tias lub zog tso zis ntawm lub peev xwm transformer tsis yog tsuas yog lub zog nquag, tab sis kuj yuav tsum tau muab faib ua ib feem kom tso tawm lub zog reactive. Lub zog tso zis ntau lawm yuav txo qis, thiab cov txiaj ntsig kev lag luam yuav txo qis. Yog li lub tuam txhab muab hluav taws xob xav kom lub zog ntawm txhua lub Hoobkas yuav tsum tsis txhob qis dua ib qho nqi, thiab yog tias nws qis dhau, nws yuav raug nplua.
