1. Voltage drop: Series txuas reactors (filter reactors) yuav tsim ib qho voltage poob. Yog hais tias qhov voltage poob yog qhov tseem ceeb, nws yuav cuam tshuam rau lub hwj chim mov zoo ntawm tus neeg siv kawg. Lub zog qhov tseem ceeb, reactor impedance, thiab kab tam sim no ntawm cov kab sib kis yuav cuam tshuam rau tus nqi ntawm qhov poob qis. Feem ntau hais lus, lub zog loj dua thiab qhov impedance ntawm lub reactor, qhov voltage poob ntau dua. Lub zog hluav taws xob hauv lub tshuab hluav taws xob ultra-high voltage feem ntau yog ntau dua 0 9, thiab qhov voltage yuav tsum tsis pub tsawg tshaj 0 95 pu. Los ntawm qhov no, nws tuaj yeem pom tau tias txhawm rau txo qhov cuam tshuam ntawm qhov poob qis los ntawm cov reactors series (filter reactors) ntawm cov khoom siv hluav taws xob zoo, qhov feem pua impedance ntawm reactors yuav tsum tsis txhob loj dhau thaum ua tau raws li qhov yuav tsum tau ua ntawm kev txwv luv luv tam sim no. .
2. Kev poob ntawm qhov system: Qhov poob ntawm cov reactors series (filter reactors) yuav tsum tau tswj hauv kev tsim. Feem ntau, lub reactor nrog cov npoo ntawm qhov poob yuav ua haujlwm ntawm qhov kub tsis tshua muaj siab, yog li nws muaj zog tshaj qhov muaj peev xwm thiab ua haujlwm ntev dua. Feem ntau hais lus, cov tshuab ziab khaub ncaws qhuav yog tsim los ntawm kev lag luam zoo tshaj plaws raws li qhov xav tau ntawm GB10229-88 \ IEC289 lossis lwm yam qauv (xws li ANSI / IEEE). Kev poob ntawm series reactors (filter reactors) yog inversely proportional to the Q coefficient, hos niaj hnub hollow reactors muaj Q coefficient siab, uas ua rau poob qis heev. Q coefficient muaj feem xyuam rau lub peev xwm ntawm lub reactor, thiab lub peev xwm loj dua, qhov loj dua Q coefficient. Rau cov reactors uas muaj peev xwm ntau dua 10 Mvar, Q coefficient yog nruab nrab ntawm 200 thiab 500, thiab qhov poob yog 0 2%-0. 5%. Tus qauv tsim ntawm kev nce Q coefficient tuaj yeem txo qhov kev poob qis ntawm cov reactors series (filter reactors), uas yog qhov zoo rau kev txo lawv cov nqi khiav lag luam, tab sis kuj nce nqi khoom siv. Cov neeg siv yuav tsum nrhiav qhov tsim nyog thiab kev lag luam sib npaug ntawm cov nqi peev thiab cov nqi khiav lag luam.
3. Transient rov qab voltage: Thaum siv series reactors (filter reactors), nws yog ib qho tsim nyog los soj ntsuam lawv cov kev cuam tshuam ntawm qhov nce ntawm qhov hloov pauv hloov pauv hloov voltage. Yog tias kev tshawb fawb pom tau tias qhov hloov pauv hloov pauv hloov pauv los ntawm cov hluav taws xob hluav taws xob ntau dhau ntawm lawv lub peev xwm tiag tiag, ntxiv lub capacitor hauv txhua theem tuaj yeem daws qhov teeb meem no thiab xyuas kom meej tias cov cuab yeej ua haujlwm ntawm qhov kev nyab xeeb. Capacitors tuaj yeem ntsia nruab nrab ntawm: (1) reactors thiab circuit breakers (kab rau hauv av); (2) Hla qhov kawg ntawm cov reactor series (filter reactor) (qee zaum ntsia hauv lub reactor); (3) Hla qhov kev sib txuas ntawm qhov hluav taws xob hluav taws xob; (4) Kev sib xyaw ua ke ntawm cov kev xaiv saum toj no. Feem ntau hais lus, lub peev xwm ntawm cov khoom siv hluav taws xob siv rau cov teeb meem kev hloov pauv hloov pauv tam sim no feem ntau tsawg dua 200 nF.
4. Electromagnetic ib puag ncig cuam tshuam: Cov xaim hluav taws xob sib nqus nyob ib ncig ntawm lub reactor series (filter reactor) loj. Vim yog cov sib nqus flux ntawm series reactor (filter reactor) tsim ib lub voj voog hauv huab cua, yog tias muaj cov khoom siv hlau nplaum xws li hlau thiab hlau hauv cov tsev nyob ib puag ncig xws li hauv av, phab ntsa, thiab lub ru tsev ntawm qhov chaw teeb tsa, series reactor (filter reactor) yuav tsim kom muaj cua sov thaum lub sijhawm ua haujlwm, ua rau lub zog ntawm cov hlau, hlau, thiab lwm yam khoom puas. Yog li ntawd, thaum lub sij hawm installation thiab layout, nws yog tsim nyog los tswj qhov tsawg kawg nkaus qhov sib txawv ntawm lub coil ntawm lub series reactor (filter reactor) thiab cov nyob ib ncig ntawm cov hlau Cheebtsam kom txo tau eddy tam sim no cua sov nyob rau hauv cov hlau thiab tsis txhob ua phem rau kev noj qab haus huv ntawm cov neeg ua hauj lwm. Cov kev tshem tawm yam tsawg kawg nkaus no yuav tsum tau ua kom ntseeg tau thaum lub sijhawm teeb tsa, tshwj xeeb tshaj yog thaum muaj steel tuav lossis cov khoom siv hauv lub hauv paus pob zeb lossis hauv pem teb. Txawm tias sab nraud ntawm qhov tsawg kawg nkaus sib nqus sib nqus, nws yog ib qho tseem ceeb kom tsis txhob muaj cov khoom siv hlau ua cov voj voog kaw. Yog tias tsim nyog, cov cuab yeej tsis sib nqus tuaj yeem siv los tswj qhov tsim nyog sib nqus qhov sib txawv hauv qab lub tshuab reactor (filter reactor).
5. Kev tiv thaiv kev teeb tsa: Tom qab kev teeb tsa lub reactor series (filter reactor), nws yuav cuam tshuam rau kev tiv thaiv cuam tshuam txog impedance lossis kev ncua deb. Rau kev tiv thaiv kev sib txawv, vim nws qhia txog qhov sib txawv ntawm qhov tam sim no, kev teeb tsa ntawm series reactance los yog tsis yuav tsis ua rau muaj kev hloov pauv loj hauv cov yam ntxwv tiv thaiv. Ib yam li ntawd, txij li lub series reactor (filter reactor) ntsia yog symmetrical nyob rau hauv peb-theem tsis, nws tsis muaj qhov tseem ceeb cuam tshuam rau xoom ib theem zuj zus thiab tsis zoo ib feem tiv thaiv cov khoom uas muaj kev cuam tshuam asymmetric Cheebtsam. Kev tiv thaiv niam sib txawv yog kev tiv thaiv sib txawv, yog li nws tsis cuam tshuam. Kev teeb tsa ntawm kev tiv thaiv kab nrog series reactors (filtering reactors) yuav tsum xav txog cov teeb meem hauv qab no: (1) kho qhov chaw ntawm TV; (2) Kho qhov chaw ntawm lub coupling capacitor; (3) Kev teeb tsa ntawm high-frequency deb pib Cheebtsam; (4) Hloov ntawm kev teeb tsa qhov tseem ceeb thaum lub serial impedance tawm haujlwm; (5) Kab rov qab logic.
