Pankhani yoyendetsa sitima, kufunikira kwa ukadaulo wapamwamba kuti ukhale wogwira ntchito bwino komanso wodalirika kukukulirakulira. Ma capacitor a filimu achitsulo awonekera ngati gawo lofunikira kwambiri pa ntchito zosiyanasiyana, makamaka mu ma inverter oyendetsera sitima ndi ma converter othandizira. Tiyeni tiwone kufunika kwa ma capacitor awa pakukweza magwiridwe antchito ndi magwiridwe antchito a machitidwe a sitima.
Ma inverter ogwiritsira ntchito sitima ndi ma converter othandizira amachita gawo lofunika kwambiri pakugwira bwino ntchito kwa njira za sitima. Ma inverter ogwiritsira ntchito sitima ndi omwe amasintha mphamvu yamagetsi mwachindunji (DC) kuchokera ku mizere ya sitima kapena njanji yachitatu kukhala mphamvu yamagetsi yosinthira (AC) kuti iyendetse ma motor ogwiritsira ntchito. Ma converter othandizira amapereka mphamvu pazinthu zosiyanasiyana monga kuyatsa, mpweya woziziritsa, ndi machitidwe olumikizirana mkati mwa sitimayo.
Ma capacitor a filimu opangidwa ndi zitsulo amagwiritsidwa ntchito kwambiri mu ma inverter oyendetsera sitima kuti azisalala, kusefa, komanso kusunga mphamvu. Ma capacitor amenewa amagwira ntchito ngati malo osungira mphamvu apakati, kuchepetsa kusinthasintha kwa magetsi ndikuwonetsetsa kuti magetsi akuyenda bwino ku ma traction motors. Amathandiza kukonza magwiridwe antchito komanso kudalirika kwa makina onse oyendetsera.
Kuchita Bwino Kwambiri: Ma capacitor a filimu okhala ndi zitsulo ali ndi mphamvu zochepa zotsutsana ndi ma series (ESR) komanso ma series inductance otsika (ESL). Izi zimapangitsa kuti kutayika kuchepe komanso kugwira ntchito bwino kwambiri posintha mphamvu, zomwe zimapangitsa kuti mphamvu zisungidwe bwino komanso kuti ma inverter a sitima azigwira ntchito bwino.
Kudalirika Kwambiri:
Kapangidwe kake kolimba komanso zipangizo zapamwamba zomwe zimagwiritsidwa ntchito mu ma capacitor a filimu zopangidwa ndi zitsulo zimapangitsa kuti zikhale zodalirika kwambiri ngakhale m'mikhalidwe yovuta yogwirira ntchito. Kapangidwe kake kodzichiritsa kokha kamatsimikizira kuti zolakwika zazing'ono kapena kuwonongeka kulikonse kumakonzedwa zokha, kuchepetsa chiopsezo cha kulephera kwakukulu ndikuwonjezera kudalirika kwa makina onse.
Kukula Kochepa:
Ma capacitor a filimu opangidwa ndi zitsulo amapezeka m'mapangidwe ang'onoang'ono, zomwe zimapangitsa kuti akhale oyenera kuyika komwe kuli malo ochepa. Kukula kwawo kochepa kumalola kuti zikhale zosavuta kuphatikiza m'zipinda zopapatiza za ma inverter oyenda ndi ma converter othandizira.
