Muva nje, i-Navitas yethule ugesi wesikhungo sedatha ye-CRPS 185 4.5kW AI, esebenzisaI-YMIN's CW3 1200uF, 450Vama-capacitors. Lokhu kukhethwa kwe-capacitor kuvumela ukunikezwa kwamandla ukuzuza isici samandla esingu-97% ekulayisheni uhhafu. Lokhu kuthuthuka kwezobuchwepheshe akugcini nje ngokuthuthukisa ukusebenza kokunikezwa kwamandla kodwa futhi kuthuthukisa kakhulu ukusebenza kahle kwamandla, ikakhulukazi emithwalweni ephansi. Lokhu kuthuthukiswa kubalulekile ekuphathweni kwamandla esikhungo sedatha nokonga amandla, njengoba ukusebenza kahle akunciphisi ukusetshenziswa kwamandla kuphela kodwa futhi kwehlisa izindleko zokusebenza.
Ezinhlelweni zikagesi zanamuhla, ama-capacitor awasetshenziselwa kuphelaukugcinwa kwamandlakanye nokuhlunga kodwa futhi kudlala indima ebalulekile ekwenzeni ngcono isici samandla. Isici samandla siyinkomba ebalulekile yokusebenza kahle kwesistimu kagesi, futhi ama-capacitor, njengamathuluzi asebenzayo okuthuthukisa isici samandla, anomthelela omkhulu ekuthuthukiseni ukusebenza kahle kwezinhlelo zikagesi. Lesi sihloko sizohlola ukuthi ama-capacitor athinta kanjani isici samandla futhi axoxe ngendima yawo ekusetshenzisweni okungokoqobo.
1. Izimiso Eziyisisekelo zama-Capacitors
I-capacitor iyingxenye ye-elekthronikhi eyakhiwe ama-conductor amabili (ama-electrodes) kanye ne-insulating material (i-dielectric). Umsebenzi wayo oyinhloko ukugcina nokukhulula amandla kagesi kusekethe yamanje eshintshanayo (AC). Lapho i-AC current igeleza nge-capacitor, inkambu kagesi ikhiqizwa ngaphakathi kwe-capacitor, igcina amandla. Njengoba izinguquko zamanje, ii-capacitorikhipha la mandla agciniwe. Leli khono lokugcina nokukhulula amandla lenza ama-capacitor aphumelele ekulungiseni ubudlelwane besigaba phakathi kwamanje kanye ne-voltage, okubaluleke kakhulu ekuphatheni amasignali e-AC.
Lesi sici sama-capacitor sibonakala ekusebenzeni okungokoqobo. Isibonelo, kumasekhethi okuhlunga, ama-capacitor angavimba i-direct current (DC) kuyilapho evumela amasignali e-AC ukuthi adlule, ngaleyo ndlela ehlise umsindo esignali. Ezinhlelweni zamandla, ama-capacitor angakwazi ukulinganisa ukuguquguquka kwamandla kagesi kusekethe, athuthukise ukuzinza nokuthembeka kwesistimu yamandla.
2. Umqondo Wesici Samandla
Kumjikelezo we-AC, isici samandla isilinganiso samandla wangempela (amandla wangempela) kumandla abonakalayo. Amandla angempela amandla aguqulwa abe umsebenzi owusizo kusekethe, kuyilapho amandla asobala engamandla aphelele akusekhethi, okuhlanganisa kokubili amandla angempela namandla asebenzayo. Isici samandla (PF) sinikezwa:
lapho u-P engamandla angempela futhi u-S engamandla abonakalayo. Isici samandla sisukela ku-0 kuye ku-1, ngamavelu asondele koku-1 abonisa ukusebenza kahle okuphezulu ekusebenziseni amandla. Isici samandla aphezulu sisho ukuthi amandla amaningi aguqulwa ngempumelelo abe umsebenzi owusizo, kuyilapho isici samandla aphansi sibonisa ukuthi inani elibalulekile lamandla liyamoshwa njengamandla asebenzayo.
3. Amandla Asebenzayo kanye Nesici Samandla
Kumasekhethi e-AC, amandla asebenzayo asho amandla abangelwa umehluko wesigaba phakathi kwamanje ne-voltage. Lawa mandla awaguquki abe umsebenzi wangempela kodwa akhona ngenxa yemiphumela yokugcina amandla yama-inductors nama-capacitor. Ama-inductors ngokuvamile ethula amandla asebenzayo, kuyilapho ama-capacitor ethula amandla angasebenzi kahle. Ukuba khona kwamandla asebenzayo kubangela ukuncishiswa kokusebenza kahle ohlelweni lwamandla, njengoba kwandisa umthwalo uwonke ngaphandle kokufaka isandla emsebenzini owusizo.
Ukuncipha kwesici samandla ngokuvamile kubonisa amazinga aphezulu wamandla asebenzayo kusekethe, okuholela ekuncipheni ekusebenzeni kahle okuphelele kwesistimu yamandla. Enye indlela ephumelelayo yokunciphisa amandla asebenzayo iwukwengeza ama-capacitor, angasiza ukuthuthukisa isici samandla futhi, ngokulandelayo, athuthukise ukusebenza kahle okuphelele kwesistimu yamandla.
4. Umthelela wama-Capacitor ku-Power Factor
Ama-Capacitor angathuthukisa isici samandla ngokunciphisa amandla asebenzayo. Uma ama-capacitor esetshenziswa kumjikelezo, angasusa amandla athile asebenzayo afakwe ama-inductors, ngaleyo ndlela ehlise inani lamandla asebenzayo kusekethe. Lo mphumela ungakhuphula kakhulu isici samandla, ukusondeze ku-1, okusho ukuthi ukusebenza kahle kokusetshenziswa kwamandla kuthuthukiswa kakhulu.
Isibonelo, ezinhlelweni zamandla ezimboni, ama-capacitor angasetshenziswa ukunxephezela amandla asebenzayo alethwa imithwalo engenisayo njengamamotho nama-transformer. Ngokungeza ama-capacitor afanelekile ohlelweni, isici samandla singathuthukiswa, kuncishiswe ukulahleka kwamandla nokwandisa ukusebenza kahle kokusetshenziswa kwamandla.
5. Ukucushwa kwe-Capacitor kuzinhlelo zokusebenza ezisebenzayo
Kuzinhlelo zokusebenza ezisebenzayo, ukumiswa kwama-capacitors kuvame ukuhlobana eduze nemvelo yomthwalo. Ngemithwalo ye-inductive (njengamamotho kanye nama-transformer), ama-capacitor angasetshenziswa ukunxephezela amandla asebenzayo afakiwe, ngaleyo ndlela kuthuthukiswe isici samandla. Isibonelo, ezinhlelweni zamandla ezimboni, ukusebenzisa amabhange e-capacitor kunganciphisa umthwalo wamandla asebenzayo kuma-transformer nezintambo, ukuthuthukisa ukusebenza kahle kokudluliswa kwamandla nokunciphisa ukulahlekelwa kwamandla.
Ezimweni ezinomthwalo ophezulu njengezikhungo zedatha, ukulungiswa kwe-capacitor kubaluleke kakhulu. I-Navitas CRPS 185 4.5kW AI yesikhungo sedatha sokuphakelwa kwamandla, isibonelo, isebenzisa i-YMIN'sCW31200uF, 450Vama-capacitor ukuze azuze isici samandla esingu-97% ekulayisheni uhhafu. Lokhu kulungiselelwa akugcini nje ngokuthuthukisa ukusebenza kahle kokunikezwa kwamandla kodwa futhi kuthuthukisa ukuphathwa kwamandla okuphelele kwesikhungo sedatha. Ukuthuthukiswa okunjalo kwezobuchwepheshe kusiza izikhungo zedatha zehlise kakhulu izindleko zamandla futhi zithuthukise ukusimama kokusebenza.
6. Amandla Womthwalo Oyingxenye kanye nama-Capacitor
Amandla okulayisha uhhafu asho u-50% wamandla alinganiselwe. Ezinhlelweni ezisebenzayo, ukucushwa okufanele kwe-capacitor kungathuthukisa isici samandla somthwalo, ngaleyo ndlela kuthuthukise ukusebenza kahle kokusetshenziswa kwamandla ekulayisheni uhhafu. Isibonelo, injini enamandla alinganiselwe angu-1000W, uma ifakwe ama-capacitor afanelekile, ingagcina isici samandla aphezulu ngisho nakumthwalo we-500W, iqinisekisa ukusetshenziswa kwamandla okuphumelelayo. Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza ezinemithwalo eguquguqukayo, njengoba kuthuthukisa ukuzinza kokusebenza kwesistimu.
Isiphetho
Ukusetshenziswa kwama-capacitor ezinhlelweni zikagesi akukhona nje okokugcina amandla nokuhlunga kodwa futhi nokwenza ngcono isici samandla nokwandisa ukusebenza kahle jikelele kohlelo lwamandla. Ngokumisa kahle ama-capacitor, amandla asebenzayo angancishiswa kakhulu, isici samandla singathuthukiswa, futhi ukusebenza kahle nokusebenza kahle kwezindleko zesistimu yamandla kungathuthukiswa. Ukuqonda indima yama-capacitor nokuwamisa ngokusekelwe ezimweni zangempela zomthwalo kuyisihluthulelo sokuthuthukisa ukusebenza kwezinhlelo zikagesi. Ukuphumelela kwesikhungo sedatha se-Navitas CRPS 185 4.5kW AI sokuphakelwa kwamandla kagesi kubonisa amandla amakhulu kanye nezinzuzo zobuchwepheshe be-capacitor obuthuthukisiwe ezinhlelweni ezisebenzayo, okuhlinzeka ngemininingwane ebalulekile yokuthuthukisa izinhlelo zamandla.
