Izingozi kuma-capacitors wamandla

2023-06-16

. Okwe-film-membrane composite dielectric capacitors, yize ukulahleka kwamandla lapho i-harmonics ivunyelwe yizikhathi ezingama-1.38 zokulahleka kwamandla ngaphandle kwama-harmonics, ama-harmonics lapho i-harmonics ivunyelwe ama-harmonics amahlandla, kepha uma okuqukethwe okuphezulu, Ngaphesheya kwe-capacitor evunyelwe, kuzokwenza i-capacitor ngaphezulu-kwamanje nokulayishwa kwamandla, ukulahleka kwamandla kudlula inani elingenhla, ukuze i-capacitor ingajwayelekile, i-infactor ephakathi nendawo yenkambu kagesi izosheshisa ukuguga. Ikakhulu lapho i-capacitor ifakwa kwigridi yamandla lapho i-voltage iye yahlanekezelwa khona, i-harmonic yegridi yamandla nayo ingakhungathekiswa, okungukuthi, into yokunwebeka nge-hamon. Ngaphezu kwalokho, ukuba khona kwama-harmonics kuvame ukwenza ukuthi i-voltage ibonakale ibukhali. I-steep-peak voltage wave idonsa kalula ukuphuma okuvela ku-Medium. Ngenxa yesilinganiso esikhulu sokushintshwa kwamandla kagesi kanye nokuqina kokukhipha okuyingxenye, kungasheshisa ukuguga kokufaka okuphakathi, ngaleyo ndlela kukufishane. Impilo yenkonzo ye-capacitor. Ngokuvamile, ngakho konke ukukhuphuka kwamandla kagesi, impilo ye-capacitor incishiswa cishe ngo-1/2. Ngaphezu kwalokho, esimweni se-harmonics ebabazekayo, iCapacitor izokweqa, ukwephulwa noma ukuqhuma.

. Okwamanje kwekhebula. Ngaphezu kwalokho, ukumelana kwekhebula, uhlangothi lwebhasi lesistimu kanye nomugqa we-wactance luxhumeke ngochungechunge nohlelo, kanye nokumelana ne-capacitor kanye nomugqa osetshenziselwa ukukhulisa isici samandla axhumekile ngokufana nohlelo, futhi I-resonance ingenzeka ngaphansi kwenani elithile lokungena kanye ne-capacitance.

. IHarmonics ibuye yandisa ukulahleka kwensimbi kwe-transformer, okubonakaliswa ikakhulukazi ekwandeni kokulahleka kwe-hysteresis emqondweni, futhi kubi kakhulu i-waveform ye-harmonic okubangelwa yi-harmonics, i-greater the hysentesis. Ngasikhathi sinye, ngenxa yokulahleka okukhulayo kulezi zinto ezingenhla ezingenhla, kuyadingeka ukunciphisa umthamo wangempela we-transformer, noma ukubheka okuqukethwe kwe-harmonic kwegridi lapho ukhetha umthamo we-transformer. Ngaphezu kwalokho, i-harmonics ibuyele futhi ukuba umsindo we-transformer ukhuphuke. Ukudlidliza kanye nomsindo we-transformer kubangelwa ikakhulukazi ama-magnetoodriction we-Iron Core. Ngokukhuphuka kwenombolo ye-harmonics, izakhi ezinemvamisa yokudlidliza ezungeze i-1Khz yandisa umsindo oxubile. Futhi ikhipha imisindo yensimbi.

. Ikakhulu, i-harmonics engemihle yokulandelana yakhiqiza amandla kazibuthe alandelanayo ajikelezayo emotweni, yakha i-torque ephambene naleyo yemoto, futhi yenza njenge-brake, ngaleyo ndlela kunciphisa ukuphuma kwemoto. Ngaphezu kwalokho, i-harmonic yamanje emotweni izodala ukuthi imoto ikhiqize ukudlidliza okwenziwe ngomshini lapho imvamisa iseduze nemvamisa yemvelo yengxenye ethile, ezodala umsindo omkhulu.

. Ngasikhathi sinye, bathinteka yithonya lama-electromagnets kanye nemisinga e-Eddy. Ukuphakanyiswa kunzima, futhi inani eliphakeme le-harmonics liwukuthi, inhloso enkulu; I-Thermal Magnetic Fion Circuit Breaker, ngenxa yezikhathi zesikhumba somqoqi somqhubi kanye nokusetshenziswa kwensimbi esekhuphukile, kubangela ukukhiqizwa kokushisa, okubangela ukuthi kukhiqizwe kwamanje ukuncipha kanye nokuhamba kwamanje ukwehla; Uhlobo lwe-elekthronikhi yohlobo lwe-elekthronikhi I-harmonic yamanje futhi kufanele inciphise yamanje yamanje, ikakhulukazi umjikelezo we-elekthronikhi othola inani eliphakeme, futhi okulinganiselwe kwamanje kuncishiswa okuningi. Kuyabonakala ukuthi izinhlobo ezintathu zokusakazwa kwamandla okusabalalisa okuchazwe ngenhla zingakhiqizwa ngenxa ye-harmonics.

Kwabaphukileyo bemisilinga yokuvuza, ngenxa yomphumela wemisivu yokuvuza ye-harmonic, abaphukileyo bezesekethe bangafudumala ngokungafanele futhi babangele ukungasebenzi kahle noma ukwehluleka. Kwama-adapter e-electromagnetic, imisinga ye-harmonic yandisa ukukhuphuka kwezinga lokushisa kwezakhi ze-magnet, okuthinta oxhumana nabo, futhi izinga lokushisa lekhoyili likhuphuka ukwehlisa amanje. Ngokudluliselwa kwe-thermal, i-rated yamanje iyancishiswa ngenxa yemisinga ye-harmonic. Konke kungadala ukungasebenzi kahle emsebenzini.

. khiqiza ukuphazamiseka. Amandla ahlanganise phakathi kokungeniswa kanye nokungeniswa kwe-elektrostiki kulingana imvamisa yokuphazanyiswa. I-conduction ihambisana nomhlaba ojwayelekile. Inani elikhulu lokugeleza okungalinganiseli esitezi esitatini, ngaleyo ndlela liphazamisa uhlelo olubuthakathaka lwamanje.

. Bathinteka kakhulu yi-harmonics. Ikakhulu imitha yamandla kagesi (ivumela uhlobo lokungeniswa ngaphezulu), lapho igagasi le-harmonic likhulu, lizokhiqiza ukudideka okulinganiswayo, isilinganiso asinembile.

. Uma imvamisa iseduze nemvamisa ye-armonic, imisebe ye-grid harmonic electronic izothinta ngqo amandla kazibuthe wobunzi bobuchophe kanye namandla kazibuthe.

Lapho i-harmonic ukungcola ukungcola kwegridi yamandla kungaphansi kweZinga Likazwelonke, ngokuvamile akuthinti uhlelo. Njengoba izinga lokungcola likhuphuka, ithonya le-harmonics liyavela kancane kancane. Endabeni yedlule kakhulu i-harmonics, imiphumela emibi ye-harmonic izovela uma i-harmonics ingalawulwa. Izici zemithombo ye-harmonic ziyinkimbinkimbi kakhulu, ngoba isizukulwane se-harmonics axhomezeki emthwalweni uqobo okhiqiza i-harmonics, kepha futhi nakuwonkendla legridi, kanye nohlobo lwemithwalo yegridi, kanye nohlobo lweminye imithwalo kugridi.
