Uchungechunge lwe-HYTSF idivayisi yesinxephezelo se-voltage ephansi yesihlungi esiguqukayo

incazelo yomkhiqizo

Le nkampani isebenzisa ubuchwepheshe be-elekthronikhi obuthuthukisiwe kanye nobuchwepheshe bokulawula obuhlakaniphile, futhi isebenzisa izindlela zobuchwepheshe eziphumelelayo njengesayensi nomnotho, ezingaxazululi kuphela inkinga yokushintsha isinxephezelo se-shunt capacitor ngaphansi kwezimo ezivumelanayo, kodwa futhi icindezela inkinga ngokuvumelana nesimo sangempela kanye nezidingo. yabasebenzisi.Noma lawula ama-harmonics, inethiwekhi yokuphakelwa kwamandla ehlanzekile futhi uthuthukise isici samandla.Ngakho-ke, lo mkhiqizo ungumkhiqizo omusha onokuqukethwe okuphezulu kwezobuchwepheshe, ubuchwepheshe obuphambili kanye nobuchwepheshe obuthembekile emkhakheni wokulawula i-harmonic ye-voltage ephansi.

isimiso sokusebenza

Izingxenye ezibalulekile ze-TSF isihlungi esinamandla aphansi we-voltage kanye nedivayisi yesinxephezelo yilezi: iyunithi yokuqapha, imojula yokushintsha, i-filter capacitor, i-reactor filter, i-circuit breaker, isistimu yokulawula kanye nesistimu yokuvikela, ikhabhinethi, njll.
Umthamo we-capacitor kusihlungi esiguquguqukayo esiphansi se-TSF kanye nedivayisi yesinxephezelo kunqunywa ngokwamandla asebenzayo adingekayo ukuze anxeshezelwe uhlelo ngemvamisa eyisisekelo;kuyilapho isisekelo sokukhetha senani le-inductance kumjikelezo we-LC sithi: Khiqiza i-resonance yochungechunge nge-capacitor, ukuze idivayisi yakhe i-impedance ephansi kakhulu (eseduze no-zero) ku-sub-harmonic frequency, okuvumela iningi lamanje le-harmonic ukuthi ligeleze. edivayisini esikhundleni sohlelo lokuphakelwa kwamandla, ithuthukisa i-harmonics yesistimu yokunikezela kwamandla kagesi Izinga lokuhlanekezelwa kwe-Wave voltage, futhi ngasikhathi sinye, i-shunt capacitor ifakwe kudivayisi ephelele yesinxephezelo samandla ashukumisayo asebenzayo, angahlangabezana nezidingo. yemithwalo eshintsha ngokushesha.

Idivayisi yesinxephezelo sesihlungi esingenzi lutho se-TSF isebenzisa ubuchwepheshe bokunxeshezelwa kwesihlungi se-LC esishunwe kanye, futhi iklanywe ngokuya ngemibandela yesayithi yomsebenzisi evumelanayo.Ama-harmonics ahlungwe ngedivayisi yesinxephezelo yesihlungi esijwayelekile ngokuvamile ahlukaniswa abe: 3rd (150Hz), 5th (250Hz), 7th (350Hz), 11th (550Hz), 13th (650Hz) njalo njalo.
Isihlungi esiguqukayo se-TSF low-voltage ashukumisayo kanye nedivayisi yesinxephezelo ixhunywe ngokuhambisana nomthwalo.

imodeli yomkhiqizo

Inkambu yohlelo lokusebenza lomkhiqizo
Isithando somlilo se-arc kagesi (i-arc cut-off kanye nesekhethi evulekile izokwenzeka phakathi nesikhathi sokuncibilika, okuholela ekungalinganisweni kwamanje kwesigaba ngasinye, i-voltage flicker, i-low power factor, kanye nama-harmonics we-oda eliphezulu angu-2~7, okuthinta kakhulu ikhwalithi yamandla igridi yamandla);
Iziteshi ezincane zokudonsa ezinikwa amandla yizitimela zikagesi (ku-6-pulse noma 12-pulse rectifiers, ezikhiqiza i-harmonics ye-oda ephezulu yesi-5, yesi-7, ne-1113, kanye nokushintsha kwemithwalo kungabangela umthelela kugridi yamandla nganoma yisiphi isikhathi);
●Ama-host amakhulu ezichwebeni nasezimayini zamalahle (imithwalo enamandla, ukushintshwa komthwalo osheshayo, nezinguquko ezinkulu, owamanje wengezwa ngokushesha emlayishweni ogcwele ngesikhathi sokuphakanyiswa, futhi esinye isikhathi cishe asilayishi. Futhi isilungisi esinikeza amandla kuwo umthombo ovamile we-harmonic. umthelela kugridi yamandla);
● I-Electrolyzer (inikwe amandla yi-rectifier transformer, ukusebenza kwamanje kukhulu kakhulu, i-rectifier izokhiqiza i-harmonics ye-5, 7, 11, ye-13 ephezulu, ezothinta ikhwalithi yamandla);

● Izigayo ze-Metallurgical/AC kanye ne-DC eziginqikayo (izigayo ezigingqayo ezishayelwa amamotho ashintsha isivinini se-AC noma ama-DC motors angabangela ukushintshashintsha kwamandla kagesi wegridi, futhi ngenxa yokuba khona kwezilungisi, aphinde akhiqize u-5, 7, 11, 13, 23, kanye Ama-harmonics aphezulu angama-25, athinta ikhwalithi yamandla);
● Ulayini wokukhiqiza wezimoto (ukudluliswa, ukushisela ugesi, ukupenda nezinye izisetshenziswa ngokuvamile zinikwa amandla yi-6-pulse noma 12-pulse rectification, ekhiqiza ama-harmonics angu-5, 7, 11, 13, 23, 25 futhi ibangele ukushintshashintsha kwamandla kagesi wegridi);
Izinkundla zokumba kanye nezihambisanayo (ngokuvamile zinikwe amandla yi-6-pulse rectifiers, i-harmonics yesi-5, yesi-7, ye-11, neye-13 zibucayi kakhulu, okwandisa okwamanje ohlelweni, kunciphisa ukusebenza kahle komsebenzi, futhi kudinga inani elikhulu lokufakwa kwe-generator);
● Umshini wokushisela onamaza aphezulu, umshini wokushisela osebenza ngogesi (indawo), isithando somlilo esimaphakathi (idivayisi evamile yokuguqula kabusha, kanye nama-harmonics ane-oda eliphezulu akhiqizwa imithwalo yethonya, ethinta kakhulu ikhwalithi yamandla wegridi);
● Izakhiwo ezihlakaniphile, izinxanxathela zezitolo ezinkulu, izakhiwo zamahhovisi (inani elikhulu lamalambu e-fluorescent, ama-projection lamp, amakhompyutha, amakheshi nezinye izinto zikagesi zingabangela ukuphazamiseka okukhulu kwamagagasi kagesi futhi kuthinte ikhwalithi yamandla);
●Izokuvikela kuzwelonke, i-aerospace (uhlelo lokuphakelwa kukagesi lwekhwalithi ephezulu lwemithwalo ezwelayo yeqoqo);
●Isistimu ye-SFC yesiteshi samandla enjini yegesi (idivayisi evamile yokuguqula kabusha, ekhiqiza ama-harmonic e-oda eliphezulu angu-5, 7, 11, 13, 23, 25, njll., ithinta kabi ikhwalithi yamandla wegridi.

Imingcele Yezobuchwepheshe

Izici
● Ukushintsha kwamanje okuyiziro: Sebenzisa ubuchwepheshe bamanje bokushintshwa kwe-thyristor obunamandla amakhulu ukuze ubone okokufaka kwe-zero-current kanye nokunqanyulwa kwamanje, akukho okwamanje, akukho mthelela (i-vacuum AC contact uyazikhethela).
