Se bracket nan kò asye ki fòme ak kat bride ki konekte ak de kondansateur nan paralèl, fòme yon estrikti ki estab ki gen ladan 1 nivo, ak ekipman prensipal la se 9 etap, fòme yon estrikti gwo kay won konbine. Nivo anpile, fasil pou demonte ak tès, ak estrikti an jeneral ki estab;

(2) Kò prensipal la adopte mòd chaj aktyèl konstan asimetri, règleman vòltaj konstan aktyèl, kontinyèlman reglabl soti nan zewo pou mete vòltaj la, epi ekipman pou pouvwa a chaje otomatikman fèmen nan moman ignisyon ak egzeyat, ak vòltaj nominal chak etap. se 200kV;

(3) estrikti gwo kay won 9-etap ak poto izolasyon kò. Chak etap gen ladan 2 MWF100-2.0 an fè boîtier lwil oliv-immersion batman kondansateur, chaje résistances, rezistans tèt vag, rezistans ke vag ak gap boul ignisyon, elatriye.

Tout boul egzeyat synchro yo loje nan yon izolasyon fèmen, ki ka manyèlman ajiste pa konsole a otomatikman ajiste espas sa a boul epi bay lè pwòp pou siye;

(4) A single pulse capacitor is 2 ± 0.05 mF, dc voltage ±100 kV, capacitor inductor £0.2 mH, oil-immersed insulation composite membrane, capacitor under normal working condition and working environment, the capacitor for casing to withstand vertical tensile 15 kg, at the same time to ensure no damage and leakage of oil;

(5) Wave head (front) resistance and wave tail resistance are of plate structure and non-inductive winding, with self-inductance £2.5mH (the purpose of reducing the inductance is to increase the load capacity. For the load with extra large capacity, an appropriate combination of external regulating capacitor and regulating resistor can be adopted to achieve the purpose of increasing the load.) , the joints are all spring-pressure relay type;

(6) Vag header (ansyen), vag ke rezistans bracket pa kat rezistans nan paralèl, tèt vag (devan), egal a longè rezistans ke a ka jenerik, epi yo chak te estoke depase rezistans vag modulation kout {{ 1}}sikwi pozisyon levye a; kout -konektè baton sikwi fasilite kouri nan seri dèlko;

(7) Seri konplè

7.1 rezistans tèt vag zèklè; 4 ansanm

7.2 vag ke rezistans 4 ansanm

(8) Gap boul premye etap la adopte deklanche bipolè bilateral, epi espas boul la dezyèm - rive nevyèm -nivo adopte twa-gap boul gap ignisyon, ak la. to synchrone move operasyon oswa to rejè pa plis pase 2 pousan; ranje a senkronizasyon Pi gran pase oswa egal a 20 pousan. .

(9) Distans espas boul la nan chak nivo ajiste lineyè pa kondwi motè a, sistèm kontwòl la endike vòltaj la chaje ki koresponn ak anplasman boul la, ak estrikti transmisyon an gen switch limit anwo ak pi ba;

(10) Distans espas boul la ka ajiste manyèlman oswa otomatikman sou sistèm kontwòl la;

(11) Kò prensipal la ka itilize nan paralèl chak de oswa plis etap, ak baton koneksyon paralèl la adopte yon konektè inifye pou fasilite echanj la. Ou ka mete rezistans depase modulation sou aparèy la san yo pa afekte pèfòmans elektrik la;

(12) Kò prensipal la ekipe ak yon izolasyon

nechèl, ak kapasite chaj li yo fèt dapre

a 120kg, pou anplwaye a ka ranplase a

onn-konpozan modulation, ak chak etap nan

tès la estoke rezistans akor ak bracket la

nan baton an koneksyon;

(13) Yo izole de bout kò a

de bout, ak pèfòmans nan sele se yon bon bagay;

(14) Yo pran mezi anti-kowona ant yo

nivo, epi pa gen okenn corona evidan ap parèt pandan

pwosesis la chaje antye.

(15) Ekipe ak yon sistèm baz sekirite, li se pratik pou pèsonèl tès la monte kò a pou ranplase rezistans lan oswa kòmanse sistèm nan tè pandan antretyen, ak tout kondansateur yo kout ak tè.

(17) Inter-izolasyon etap ak sipò mekanik ka kenbe tèt ak 220kV DC san yo pa jenere egzeyat.

(18) Nechèl la izolasyon k ap grenpe enstale sou kò a, nechèl la izolasyon se pratik ak san danje epi serye, ak machin nan kò ka konplètman satisfè fòs la mekanik ak elektrik.

(19) Tèt dèlko enpak la ekipe ak yon kouvèti egalize vòltaj ki fòme ak yon fèy aliminyòm ki gen fòm tòti-.
