Incazelo Yomkhiqizo

Uchungechunge lwe-TBBWZ lwangaphandle lwedivayisi yesinxephezelo esizenzakalelayo samandla asebenzayo okuzenzakalelayo kukholomu (ngemuva kwalokhu ebizwa ngokuthi idivayisi) ilungele izintambo zokudlulisa ezingu-3kV, 6kV, 10kV futhi ifakwe kumakholomu angaphandle.Isetshenziselwa ukuthuthukisa isici samandla, ukunciphisa ukulahleka komugqa nokuthuthukisa ikhwalithi ye-voltage.
Le divayisi ithobelana nezindinganiso ze-JB/T10558-2006 "Idivayisi Yesinxephezelo Samandla Anamandla Anamandla Aphezulu Kagesi Kukholomu", DL/T604-1996 "Izimo Zobuchwepheshe Zoku-oda Idivayisi Ye-Voltage Shunt Capacitor" nokunye.
Idivayisi ingasetha amapharamitha ngokwezidingo zangempela.Isilawuli kudivayisi siqapha amandla asebenzayo nesimo se-voltage yolayini ngesikhathi sangempela, futhi siyahlulela futhi sihlaziye ngokuya ngesethi yamandla asebenzayo kanye necebo lokulawula amandla kagesi, ukuze kubonakale ibhange le-parallel capacitor elihambisana nevoltage ephezulu.Ukushintsha okuzenzakalelayo.Ngesikhathi esifanayo, idivayisi inemisebenzi yokuvikela ephelele, efana nokuvikelwa kwe-busbar short-circuit-break-break, ukuvikelwa kokulibaziseka kwesikhathi esifushane kwe-capacitor, ukuvikelwa kokulibaziseka kwesikhathi esifushane kwe-capacitor overcurrent, ukuvikela ukugcwala ngokweqile, ukuvikelwa kwe-undervoltage, ukuvikelwa kokulahlekelwa kwesigaba. (uyazikhethela lapho uyala) kanye Nokuvikela Ukwenqatshwa kanye neminye imisebenzi, kodwa futhi inomsebenzi wokufunda imitha.
I-vacuum contactor esetshenziswe kulolu cingo ihlangabezana ngokugcwele nezidingo zezinga lezwe lonke le-GB7675-87 lokushintshwa kwe-capacitor, futhi inezici zokuvula nokuvala okuhle kokuxhumana, amandla okucindezela i-arc aqinile, nempilo ende yesevisi.I-high-voltage parallel capacitor ihlanganisa ukumelana nokukhishwa kwangaphakathi futhi ifakwe i-fuse yangaphandle yokuphuma, ephephile futhi enokwethenjelwa.Isilawuli esizenzakalelayo se-high-voltage capacitor sangaphandle sikhethiwe, esinekhono eliqinile lokulwa nokuphazamiseka, imisebenzi ephelele kanye nekhwalithi enhle kakhulu.

Imishini kagesi esemqoka kanye nolwazi loku-oda

Impahla kagesi eyinhloko:
1. Ama-Capacitors
Le divayisi ikhetha i-BFM noma i-BAM full-film high-voltage parallel capacitor ekhiqizwe yinkampani yethu, futhi ama-capacitor ane-discharge resistors eyakhelwe ngaphakathi.
Qaphela: Nakuba ukushajwa kwe-capacitor kukhishwe ngaphansi kwe-50V ngokusebenzisa i-resistor yokukhipha ngemuva kokuthi i-capacitor ingasebenzi imizuzu engu-5, i-capacitor ayikwazi ukuthintwa ngesandla.I-capacitor ingathinteka kuphela ngemuva kokuthi amatheminali ayo asekelwe ngokuthembekile.Bheka imanuwali yemiyalo ye-capacitor ukuze uthole imininingwane.
2. Indoor AC high voltage vacuum contactor
I-AC high-voltage vacuum contactor iyisizukulwane esisha semishini yokushintsha i-capacitor, izinkomba zayo zobuchwepheshe zihlangabezana nezidingo zezinga likazwelonke le-GB7675-87 "AC high-voltage vacuum circuit breaker yokuvula nokuvala i-capacitor bank test", futhi inempilo ende, kufika izikhathi ezingu-200,000 ngesikhathi esilinganiselwe.Lokhu kubaluleke kakhulu ekushintsheni njalo ukuze uthole isinxephezelo samandla asebenzayo.Sicela ubheke imanuwali yeziqondiso ze-vacuum contactor ukuze uthole imininingwane.
Uma umsebenzisi edinga, ungaphinda ukhethe iswishi yokulayisha i-sulphur hexafluoride noma iswishi ye-vacuum yekholomu.
3. Idivayisi yokulawula okuzenzakalelayo ye-voltage ephezulu ye-voltage capacitor
Isilawuli esizenzakalelayo se-high-voltage capacitor senziwa ngobuchwepheshe be-microcomputer.Ngokuthatha isampula i-voltage yesistimu kanye nesistimu yamanje ngesikhathi sangempela, ingashintsha ngokuzenzakalelayo ama-capacitor ngokuya ngamasu anjengesikhathi, i-voltage, isici samandla nezinhlanganisela zawo.Ububanzi bokushintsha bungasethwa ngokungafanele ngumsebenzisi ngokuya ngesimo sangempela somugqa.ukuze kuzuzwe umphumela omuhle kakhulu wokunxeshezelwa.Ngesikhathi esifanayo, isilawuli esizenzakalelayo sinikezwa ukuvikelwa kwe-over-voltage, ukuvikela ngaphansi kwe-voltage, ukuvikela okungaphezu kwamanje kanye nemisebenzi yokulibaziseka, futhi inani laso lokusetha lingasethwa njengoba kudingeka.Uma iphutha langaphakathi le-capacitor lenzeka futhi uhambo oludlulayo lwenzeka, isilawuli esizenzakalelayo sizozivimbela.Isilawuli singarekhoda imicimbi, futhi sihlome ngesixhumi esibonakalayo ukuze sixhumane namadivayisi ahlakaniphile angaphandle ngendlela enezintambo noma engenantambo.Ukuze uthole imininingwane, sicela ubheke imanuwali yesilawuli enamathiselwe emkhiqizweni.
4. Isibambi se-zinc oxide
I-HY5WS yohlobo lwezinc oxide arrester isetshenziselwa ukuvikela ukugcwala kombani, isetshenziselwa ukuvikela iziguquli zamandla okulawula kanye nezixhumi ze-vacuum.I-HY5WR Zinc Oxide Arrester isetshenziselwa ukuvikela i-capacitor kanye nokuvikela ukusebenza kwe-overvoltage.
5. I-voltage transformer uhlobo lwe-transformer
Ingxenye ihlinzeka ngamandla okusebenza kagesi aphansi, futhi iphinde isebenze njenge-voltage transformer ukuze inikeze isampula ye-voltage yomugqa.Isilinganiso sokuguqulwa singu-10/0.22kV noma 6/0.22kV, futhi ukunemba kuyileveli 1.
6. I-fuse yokuyeka
I-RW10-10F fuse yokuphuma, isilinganiso se-creepage ≥25mm/KV, umthamo wokuphuka olinganiselwe ngu-100MVA.I-fuse yenziwe ngohlobo olusha lwe-"T" oluncibilikayo oluthuthukiswa uMnyango Wezinsiza Zikazwelonke, olunezici ezinhle kakhulu zokuhlanganisa.Isilinganiso samanje se-fuse akufanele sibe ngaphansi kwezikhathi ezi-1.5 zamanje ezilinganiselwe zedivayisi, kodwa akufanele sibe sikhulu kakhulu.Kufanele ihlangabezane nalezi zidingo ezilandelayo: Ngokuvumelana nenani eliphakeme lamanje lesekethe emfishane endaweni yokufaka, hlola ijika lesici se-ampere/sesibili se-fuse, futhi isikhathi se-fuse kufanele sibe ngaphansi kwamasekhondi angu-0.15.
7. I-transformer yamanje (yesampula yesici samandla)
I-transformer yamanje yohlobo lwe-LZKW-10 ishiya ifekthri inamandla okuvama ukumelana no-voltage ongu-35kV futhi idlula ngomzuzu owodwa (American National Standard).I-transformer inesakhiwo esinengqondo kanye nokunemba okuphezulu kokulinganisa.Ukufakwa okulula nempilo ende yesevisi.
