I-reactive power compensation capacitor contactor ngokuvamile esiyibiza nge-capacitor contactor, imodeli yayo yi-CJ 19 (abanye imodeli yabakhiqizi yi-CJ 16), amamodeli avamile yi-CJ 19-2511, CJ 19-3211, CJ 19-4311 kanye ne-CJ 19-6521, CJ 19-9521.
Ukuze sazi inhloso yemigqa emithathu, okokuqala sidinga ukuqonda isakhiwo se-contactor.
Eqinisweni, iqukethe izingxenye ezintathu:
1. Ingxenye yokuxhumana yi-CJX 2 uchungechunge lwe-AC contactor, njenge-CJ 19-3211 i-contactor yayo yi-CJX 2-2510 njengesixhumi esiyisisekelo.
2. Oxhumene naye, noma omhlophe ongumsizi ngenhla kothintana naye, uhlanganisa abathintwayo abathathu abafakwa ugesi njalo kanye nothintwayo ovamise ukuvaleka.Ngenxa yezinto zokuklama, ithinta othintana naye ngaphambi kothintana naye oyinhloko.
3. Umugqa wokudambisa, okuyimigqa emithathu.Ekhuluma ngokudambisa, empeleni intambo ene-resistivity enkulu, eyaziwa nangokuthi umugqa wokumelana, olingana nokumelana namandla aphezulu, indima yayo ukuvimbela umphumela wamanje.
Siyazi ukuthi i-capacitor iyisici sokugcina amandla, izici zayo eziyisisekelo yilezi: I-AC ukumelana ne-DC, imvamisa ephezulu yokumelana ne-frequency, yamanje yi-voltage yangaphambili engu-90 degrees kanye nezici zomzimba ze-inductor, ngakho isetshenziselwa ukunxephezela amandla asebenzayo emugqeni we-offset.
Ukwazi izici ze-capacitor, khona-ke lapho i-capacitor ifakwe ugesi, ngoba iyinto yokugcina amandla, uma isanda kufakwa ugesi, ibophezelekile ukukhiqiza ukushaja okukhulu kokushaja.Imanje layo ngokuvamile liyizikhathi eziningi zesilinganiso samanje se-capacitor, bese lizobola ngomjikelezo wokushaja kuze kube yilapho ukusebenza kwamanje okuvamile.
Lokhu kugeleza kokuqhuma kubulala kakhulu empilweni yesevisi ye-capacitor, ngoba umthwalo welayini uzoshintsha amandla asebenzayo omugqa, okudingekayo ukulungisa njalo inani lokungenayo kanye namaqembu esinxephezelo se-capacitor ukuze kuzuzwe umphumela omuhle kakhulu wesinxephezelo.
Ngemuva kokusebenzisa i-contactor ye-capacitor, lapho othintana naye osizayo kanye nomugqa wokudambisa ku-contactor kuxhunywe okwamanje, umugqa wokudambisa usetshenziselwa ukucindezela ukungena kwe-capacitor, ukuze kuvikelwe i-capacitor nokwandisa impilo yesevisi ye-capacitor.
Lesi sixhumi se-capacitor sokusika isinxephezelo samandla esisebenzayo ngokuyisisekelo sifana nejometri nokubukeka koxhumana nabo abavamile, amapheya amathathu kuphela oxhumana nabo abasizayo.Kungani kukhona abathathu abathintwayo abasizayo?Uma ubhekisisa, lokho akuyena othintana naye osizayo, kukhona intambo yokumelana kuyo, akunjalo?
Iwukumelana nomkhawulo wamanje, ngesikhathi sokuthumela amandla ku-capacitor, i-capacitor izokhiqiza umsinga wokushaja omkhulu, obizwa ngokucacile ngokuthi u-surge, uchaza incazelo yamanje esheshayo.Lesi sakamuva singaba izikhathi eziningi inani lamanje elilinganiselwe le-capacitor, i-current enkulu kangaka esheshayo idala umonakalo kothintana naye, i-capacitor nezinye izingxenye zikagesi ze-capacitor, futhi iphinde ibe nomthelela ohlelweni.
Ukuze unciphise ukugeleza kokuhlinzwa, ukumelana nomkhawulo wamanje kwengezwe, futhi i-current encane ikhokhiswa ngaphambili ku-capacitor yesinxephezelo lapho kufakwa.Lapho ikhoyili ye-contactor ishajwa, ukumelana nomkhawulo wamanje kuqala kuxhuma ukunikezwa kwamandla kanye ne-capacitor ukushaja i-capacitor.Ngalokhu kumelana, ukuhlinzwa kungakhawulwa izikhathi ezingu-350;khona-ke othintana naye oyinhloko we-contactor uvaliwe, ukuze kube noshintsho olubushelelezi.
Ama-capacitor esinxephezelo samandla ahlukene, ukucaciswa kwabathintana nabo abafanayo kuhlukile, futhi kumakwe ku-capacitor, kungalinganiselwa futhi.
