Iyo OTIS OVF20 inverter inoita basa rakakosha muhurongwa hwemazuva ano hweelevator, ichivimbisa kushanda zvakanaka uye kwakachengeteka. Basa rayo guru nderekushandura simba reAC rinopihwa kuelevator kuita AC output inodzorwa, inochinja-chinja frequency iyo inotyaira mota zvakanaka.
Maitiro acho anotanga nesimba reAC rinouya, ringave 380V kana 220V, iro rinotanga rachinjwa kuita DC voltage ne rectifier system iri mukati me inverter. Iyi DC voltage inozogadzikiswa nema capacitors ari muDC circuit kuti ipe simba rakasimba. Inverter inoshandisa pulse-width modulation (PWM) system kushandura iyi DC yakagadziriswa kuita AC voltage ine adjustable frequency, zvichipedzisa maitiro e inverter.
Mukati meOVF20, chinhu chekutanga chinoonekwa mushure mekuvhura chifukidziro chepamberi iMotion Control Board II (MCBII). Sezvinoratidzwa nezita rayo, bhodhi iri rine basa rekudzora sisitimu yekufambisa yeelevator. Rinoshanda senzvimbo yekubatanidza masaini ese ekupinda nekubuda eOVF20 uye rinogadzirisa masaini aya kuti rive nechokwadi chekuti anoshanda nemazvo.
Sisitimu yekudzora elevator—yakadai seLBII, LCBII, kana mamwe mabhodhi ekudzora—inotumira mirairo yekumhanya kuMCBII. MCBII inogadzirisa mirairo iyi pamwe chete nemamwe masaini ekukwira, kusanganisira maseketi ekuchengetedza. Inozotumira masaini ekudzora kuPower Drive Board (PDB), iyo inotarisira ma transistors ane simba guru mukati me inverter kuti iite shanduko chaiyo ye AC. Chaizvoizvo, PDB inoshandura simba re inverter ichitungamirirwa ne MCBII.
Kuti ishande nemazvo, MCBII inogamuchirawo mhinduro kubva kuPVT speed sensor. Nekuenzanisa kumhanya chaiko kweelevator nekumhanya kwakarairwa, MCBII inogadzirisa kubuda kwemota kuti irambe ichifamba zvakanaka uye zvakavimbika. Mitsetse miviri yekuwedzera kubva kuinverter inopa mhinduro yemagetsi kuMCBII sechikamu chesystem yekudzivirira magetsi yemukati meinverter. Kana magetsi anobuda akadarika kukosha kwakarongwa, inverter ichaita kuti dziviriro ivharwe.
Chekupedzisira, OVF20 ine sisitimu yekudzivirira mabhureki. Iyi resistor inoshandiswa kuderedza simba remuchina wekusimudzira mafuta, ichishandura simba rakawandisa kuita kupisa kuitira kuti ikwanise kumira zvakanaka uye zvakachengeteka.
Kazhinji, inverter yeOTIS OVF20 inosanganisa kudzora kufamba kwakarurama, mhinduro chaiyo, uye nzira dzekuchengetedza kuti ipe mashandiro akavimbika kune maelevator emazuva ano.
