Amazinga aphezulu

I-GB50227-2008 “Ikhodi yokuklama idivayisi ye-shunt capacitor

I-JB/T7111-1993 “Idivayisi ye-high voltage shunt capacitor”

I-JB/T10557-2006 “Idivayisi yesinxephezelo yasendaweni esebenza ngamandla kagesi aphezulu”

I-DL/T 604-1996 “Uku-oda izimo zobuchwepheshe zama-high voltage shunt capacitor”

Inkomba yokusebenza kwezobuchwepheshe eyinhloko

1.Ukuchezuka kwamandla

1.1 Umehluko phakathi komthamo wangempela namandla alinganiselwe wedivayisi angaphakathi kwebanga elingu-0- +5% lamandla alinganiselwe.Izinga liphakeme kunezinye izimboni

1.2Isilinganiso sobukhulu ukuya kobuncane bekhono phakathi kwanoma yimaphi amatheminali emigqa emibili yedivayisi ngeke seqe u-1.02.

2.Ukuchezuka kwe-inductance

2.1Ngaphansi kwesilinganiso samanje, ukuchezuka okuvumelekile kwevelu yokusabela ngu-0~+5%.

2.2Inani lokusabela lesigaba ngasinye ngeke lidlule ± 2% yenani elimaphakathi lezigaba ezintathu.

Isakhiwo kanye nomgomo wokusebenza

I-1.Idivayisi iyisakhiwo sekhabhinethi noma isakhiwo sefreyimu, esingashintsha ibhange le-capacitor ngesandla, futhi ingahlonywa nge-voltage kanye nesilawuli esizenzakalelayo samandla asebenzayo ukuze sishintshe ngokuzenzakalelayo ibhange le-capacitor.

2.Idivayisi yesakhiwo sekhabhinethi iqukethe i-switchgear engenayo ehlukanisayo, ikhabethe le-reactor yochungechunge, ikhabethe le-shunt capacitor kanye nebhasi elixhunyiwe.Ikhabhinethi ye-capacitor ingakwazi ukunquma inani lamakhabhinethi ngokuya ngomthamo wesinxephezelo kanye nohlelo lokusetha, oluvame ukwakhiwa ngamakhabethe amaningi.Umzimba wekhabhinethi wenziwe ngepuleti lensimbi eligoqiwe lekhwalithi ephezulu eligoqekayo noma umhlangano wokugoba wepuleti le-aluminium-zinc.

I-3.Isakhiwo sesakhiwo: lapho umthamo olinganiselwe we-capacitor eyodwa ungama-kilowatts angu-30, ibhange le-capacitor lakhiwa uhlaka olunemigqa emibili (eyodwa) enemigqa emibili, lapho umthamo olinganiselwe ungaphezu kwama-kilowatts angu-100, ungqimba olubili (olulodwa) isakhiwo esinemigqa emibili, futhi lapho umthamo olinganiselwe ungaphezu kwama-kilowatts angu-200, ungqimba olulodwa (olulodwa) lwemigqa emibili.

I-4.Idivayisi yesakhiwo sefreyimu yakhiwe ngohlaka lokuxhuma, i-air co re reactor eyomile, ifreyimu ye-shunt capacitor kanye nocingo.Kuhlanganisa i-zinc oxide arrester, i-shunt capacitor, i-fuse eyodwa evikelayo, ikhoyili yokukhipha evalwe ngokugcwele, isivikeli seposi, ibha yebhasi yethusi (i-aluminium) kanye nohlaka lwensimbi.

•Isethi ye-capacitor ibekwe eshelufini ohlakeni lwensimbi, futhi ibhasi lokuxhuma kanye nama-insulators ezinsika ahlanganiswa ukuze enze isekethe eyinhloko ngokuya ngemodi yokuxhumana esethiwe.

• Isakhiwo sebhange le-capacitor ngokuvamile sihlanganisa uhlobo, olunesakhiwo esiqinile nesizinzile, insimbi yokulondoloza kanye nokufakwa okulula nokuhamba.

•Izinhlobo zokufakwa kwe-capacitor zingahlukaniswa zibe umugqa owodwa uhlobo lwezingqimba ezintathu, umugqa ophindwe kabili uhlobo olulodwa lwengqimba kanye nesakhiwo semigqa ekabili.

•Isigaba ngasinye se-capacitor sivamise ukuxhunywa ngokuhambisana bese kuba uchungechunge.Ingaphezulu lefreyimu yensimbi ifakwe idiphu elishisayo noma ifuthwe ngepulasitiki.

•Uthango (ukuphakama okungu-1.8m) lungasethwa luzungeze yonke idivayisi njengoba kudingekile.Indawo yocingo ifafazwa ngepulasitiki.Izinto zohlaka zenziwe ngamaphrofayili ekhwalithi ephezulu.Bheka umdwebo 11-Fig.17 ukuze uthole uhlaka kanye nombono wesakhiwo.

5.Ukukhethwa kwe-reactor yochungechunge

Ama-reactor ochungechunge afakwe ohlangothini olumaphakathi ngokuvamile akhetha i-reactor ewumongo owomile;ama-reactor ochungechunge afakwe ohlangothini lwamandla ngokuvamile akhetha i-air-core reactor, engapakishwa ngezigaba ezintathu noma ifakwe kufonti.

6.Ukuvikela nokulawula okwesibili

Ibhange le-capacitor lamukela idivayisi yokuqapha i-microcomputer capacitor, efakwe ngaphambili kwe-switchgear ephezulu.Inezindlela ezimbili zokulawula: i-manual kanye ne-remote automatic control, futhi zombili ziyavimbana.

Ebhange le-capacitor elidinga ukulawulwa kokushintsha okuzenzakalelayo, idivayisi yokulawula amandla kagesi kanye namandla asebenzayo noma isilawuli sesici samandla sisetshenziselwa ukushintsha ngokuzenzakalelayo ibhange le-capacitor ngesampula, ukuhlaziya okunengqondo kanye neswishi yokushintsha imiyalelo.Isilawuli sithwala i-RS232 noma i-RS485 yokuxhumana, engaxhunywa nezinye izisetshenziswa zokuqapha esiteshini esincane ukuze kwakheke uhlelo oludidiyelwe lwesiteshi esishintshashintshayo esingaphansi ukuze sihlangabezane nezimfuneko zezindlela ezihlukahlukene zokusebenza nokuphatha ezifana nesiteshi esincane esinganakiwe noma esingenamuntu kanye nokulawula okuphakathi nendawo.

7.Imfuneko ye-Interlock

Ikhabethe elingenayo lifakwe i-grounding switch kanye ne-circuit breaker mechanical inter-locking kanye ne-interlocking kagesi, futhi i-capacitor ngayinye ihlinzekwa ngokhiye we-electromagnetic kanye nokhiye womnyango, odlala indima yokuvikela ukuphepha.Lapho yonke iminyango yekhabhinethi ingavunyelwe ukuvala noma ukuvula ngokuthanda kwayo ngesikhathi sokusebenza, ukushintshwa okuyinhloko kuzohamba ngokushesha;ngesakhiwo sefreyimu, umsebenzisi kufanele afake isikhiya sekhodi semishini kumshini wokusebenza weswishi ehlukanisayo kudivayisi ye-capacitor kanye nomnyango wocingo ukuze kwakheke umsebenzi ophuthelwe ukuvinjwa nge-breaker circuit yangaphambili.Umnyango wocingo kufanele uvaliwe ngaphambi kokusebenza futhi akufanele uvulwe ngesikhathi sokusebenza, ukuvimbela ngokuqinile ukwenzeka kwazo zonke izinhlobo zokungasebenzi kahle.
