I-TBB Series 6-35KV 100-10000Kvar High Voltage Shunt Capacitor Isethi Ephelele

Izici:
1. Idivayisi ingasebenza isikhathi eside ngaphansi kwe-voltage eqinile ye-voltage ephindwe izikhathi ezingu-1.1 i-voltage elinganisiwe;
2. Idivayisi ingasebenza ngokuqhubekayo ngaphansi kwe-overcurrent okuyimpande yayo enenani eliyisikwele ingeqi izikhathi ezingu-1.3 kunamanje olinganiselwe webhange le-capacitor;
3. Idivayisi ithatha i-high-voltage circuit breaker ngaphandle kwesindayo, futhi ifakwe isibophisi se-oxidized breakdownd cast ukuze sibeke umkhawulo ku-overvoltage yokusebenza okukhiqizwa lapho ushintsha amabhange e-capacitor;
4. Kumadivayisi angu-6kV no-10kV, iswishi ye-vacuum load, i-vacuum circuit breaker noma i-SF6 ye-circuit breaker isetshenziswa njengokushintshashintsha kwebhange le-capacitor.Kumabhange e-capacitor ane-capacitance encane, i-vacuum contactors kufanele isetshenziselwe ukushintshwa kweqembu, futhi ama-circuit breakers noma ama-SF6 switch kufanele asetshenziselwe amabhange e-capacitor ane-capacitance enkulu;
5. Idivayisi ikhetha uhlobo olomile lwe-air-core reactor exhunywe ohlangothini lokuphakelwa kwamandla kwedivayisi noma i-iron-core reactor yohlobo olomile exhunywe endaweni emaphakathi yedivayisi ukuze kukhawulwe i-inrush current evalayo, cindezela okuphezulu- oda ama-harmonics, futhi uthuthukise i-voltage waveform yenethiwekhi.I-reactor enezinga lokusabela elilinganiselwe lika-0.5-1% isetshenziselwa ukukhawulela ukuvala kwamandla wamanje;i-reactor enezinga lokusabela elilinganiselwe lika-5-6% isetshenziselwa ukucindezela i-harmonics yesi-5 nangaphezulu futhi ikhawule i-inrush current yokuvala;isilinganiso sokusabela esilinganiselwe singu-12-13%.Isetshenziselwa ukucindezela i-harmonics yesi-3 nangaphezulu futhi ikhawulele ukuvala i-inrush current;
6. Idivayisi isebenzisa ikhoyili yokukhipha uhlobo lwe-FDGR, enganciphisa insalela yebhange le-capacitor ukusuka enanini eliphakeme le-voltage elinganiselwe ibe ngaphansi kokuphindwe izikhathi ezingu-0.1 ku-voltage elinganiselwe phakathi kwama-5s;
7. Ngokwezidingo zohlelo kanye nabasebenzisi, idivayisi ingasebenzisa isilawuli sasendaweni noma igumbi lokulawula elikhulu, isilawuli esimaphakathi noma isilawuli esizenzakalelayo;
8. Ukuvikelwa kwe-voltage kusebenzisa ukuvikelwa kwe-fuse ye-capacitor eyodwa njengesivikelo esiyinhloko, unxantathu ovulekile, umehluko we-voltage, umugqa ongathathi hlangothi ongalinganiseli wamanje njengesivikelo sokulondoloza, ngaphezu kwalokho, idivayisi iphinde ifakwe ukuvikelwa kwe-overcurrent, overvoltage kanye nokulahlekelwa kwe-voltage.Ukugcwaliseka kwalokhu kuvikela kungaphinda kukhethe idivayisi yokuqapha ukuvikela i-microcomputer capacitor esebenza kangcono ukuze kuzuzwe izidingo zokuvikela i-capacitor relay.
Izici zesakhiwo:
1. Idivayisi engu-6~1OkV iqukethe i-switchgear enamandla amakhulu (okuhlanganisa ama-circuit breaker, amaswishi ahlukanisayo anamandla kagesi aphezulu, ama-transformer amanje, isivikelo se-relay, amathuluzi okulinganisa), ama-reactor ochungechunge, amakhoyili akhiphayo, izibambisi ze-zinc oxide, amaswishi aphansi, kanye ne-single capacitor. isivikelo.Iqukethe i-fuse, i-capacitor ehambisanayo, ibha yokuxhuma kanye nohlaka lwesakhiwo sensimbi.Inkanyezi ephindwe kabili ihlanganisa ne-transformer yamanje yomugqa ongathathi hlangothi wokuvikela kwamanje okungalingani.
2. Ikhabethe lokushintshwa kwamandla kagesi aphezulu ledivayisi engu-6~1OkV lifakwe egunjini lokushintshela.Ukuhlelwa kwamabhange e-capacitor kanye nama-reactors ochungechunge kuhlukaniswe ngezinhlobo ezintathu: uhlobo lwekhabhinethi yasendlini, uhlobo lohlaka kanye nohlobo oluhlangene.
a.Uhlobo lwekhabhinethi yasendlini
Ibhange le-capacitor lakhiwe ikhabethe elilodwa elingenayo kanye namakhabethe amaningana e-capacitor ngokuya ngemininingwane ehlukene yamandla.Amakhoyili akhiphayo, amaswishi aphansi kanye nezibambisi ze-oxidation zifakwe kukhabhinethi engenayo.Ikhabhinethi ye-capacitor ihlanganisa ama-parallel capacitor, i-fuse eyodwa yokuvikela i-capacitor, kanye newindi lokubuka le-capacitor elikhanyayo kuphaneli yomnyango.
b.Uhlobo lozimele
Ibhange le-capacitor lihlanganisa ifreyimu yokungena kanye nohlaka lwe-capacitor.Lonke uhlaka lwedivayisi luhlukaniswe ngamaphaneli amaningana, abese ehlanganiswa esizeni.Ifreyimu yocingo ifakwe ikhoyili yokukhipha amanzi, iswishi yaphansi kanye nesibambisi se-oxidation.Uxhumano lwezinkanyezi ezimbili luphinde lube ne-transformer yamanje yomugqa ongathathi hlangothi wokuvikela kwamanje okungalingani.Isakhiwo se-capacitor sihlanganisa ama-capacitor afanayo kanye namafuse okuvikela i-capacitor eyodwa.Izinsimbi ezinezikhala zensimbi zingasethwa ngaphandle kohlaka noma iminyango yensimbi enezikhala ingasethwa ohlakeni.
c.Iqoqo
Uhlobo oluhlangene luyindlela yebhange le-capacitor elakhiwe ngama-collel parallel capacitor.Isakhiwo esihlanganisiwe, okuhlanganisa i-reactor yochungechunge, i-collel parallel capacitor kanye nekhoyili yokukhipha.
3. Idivayisi ye-35kV iqukethe i-switchgear enamandla amakhulu (okuhlanganisa ama-air-voltage circuit breaker, ama-transformer amanje, ukuvikela i-relay, izingxenye zokulinganisa nezinkomba), ama-reactor ochungechunge, amakhoyili akhiphayo, izibambisi zikagesi ezine-oxidized, ama-fuse okuvikela okukodwa, ama-capacitor afanayo, njll. .Uxhumo lwenkanyezi ekabili kanye ne-transformer yamanje yomugqa ongathathi hlangothi ukuvikela kwamanje okungalingani, wonke amadivaysi awuhlaka lohlaka.
4. Izintambo ze-reactor yochungechunge
I-air-core reactor ifakwe ngaphambi kwebhange le-capacitor, okungukuthi, uhlangothi lokunikezwa kwamandla, futhi i-iron-core reactor ifakwe ngemuva kwebhange le-capacitor, okungukuthi, uhlangothi olungathathi hlangothi lwedivayisi.
