Mokhoa oa ho lekola phoso ea inverter

Mokhoa oa ho lekola phoso ea inverter

Ho tloaelehile haholo indastering ea inverter. Mokhoa oa ho lekola phoso kamora hore inverter e sebelisoe nako e telele?
Bakeng sa ho etsa hore inverter e sebetse ka mokhoa o tloaelehileng, e tlameha ho kengoa ka tatellano ho latela litlatsetso tsa tekheniki le litaelo tsa inverter ha e sebelisoa, 'me e tlameha ho fihlela litlhoko tsa phepelo ea motlakase le tikoloho ea ts'ebeliso. Matla a sebelisoang haholo a ho kenya inverter ke mekhahlelo e meraro ea 380V480 V, e ka feto-fetohang khafetsa ka 10%. Palo ea phepelo ea motlakase oa leqhubu le lekhuts'oane ke 50 / 60Hz, 'me phallo ke 5%. Bafetoleli ba maqhubu a inehetseng ke taba e 'ngoe.

1. Ho fumanoa ha potoloho ea li-rectifier ha ho fumanoa static ea frequency converter

Ha inverter e lekoa ka lipalo, ho hlokahala hore o leke potoloho ea rectifier kamora hore inverter e fuoe motlakase. Ntlha ea pele, tlosa lisebelisoa tsohle tsa inverter; Taba ea bobeli, fumana li-circuits tse ntle le tse mpe tsa DC ho inverter, ebe o bula konopo ea multimeter ho diode block. Ntlha ea boraro, hokela probe e ntšo le probe e khubelu ho lipalo tse ntle le tse mpe tsa bese ea DC le terata e hlahisang terata e meraro ka tatellano, 'me u tlalehe litekanyetso tse tharo tsa motlakase tse bontšitsoeng ke multimeter; haeba litekanyetso tse tšeletseng tse lekantsoeng tsa multimeter li lekana, e bonts'a hore borokho ba khalemelo bo tloaelehile, ho seng joalo bo supa Ho na le bothata ka borokho bo lokisang 'me bo hloka ho fetoloa kapa ho nkeloa sebaka.
Phumano ea potoloho ea inverter ka phumano e sa fetoheng ea frequency converter

Tekong ea static ea inverter, tlhahlobo ea potoloho ea inverter le teko ea potoloho ea rectifier li batla li tšoana, 'me ka bobeli li etsoa ha inverter e tima. Phapang ke hore tekong ea potoloho ea inverter, kotola ea multimeter e lokela ho fetoloa ho hanyetsa × likere tse 10, li-probe tse khubelu le tse ntšo li lokela ho hokahanngoa le palo e mpe ea bese ea DC ka tatellano, 'me u ikopanye le sephetho sa likhechana tse 3 tsa terata ho ngola potoloho ea inverter ka thoko 'Me u tlalehe boleng ba ho hanyetsa Litekanyetso tse tharo tsa ho hanyetsa tse bontšitsoeng lekhetlo la ho qetela lia lekana, 'me boleng bo bontšitsoeng ka lekhetlo la ho qetela ke OL. Sebelisa mokhoa o ts'oanang ho hokela probe e ntšo le palo e ntle ea bese ea DC, 'me liphetho tsa litekanyo lia fetoha, ho bontša hore inverter e tloaelehile. Ho seng joalo, e bonts'a hore ho na le bothata ka module ea inverter IGBT ea inverter, mme module ea IGBT e hloka ho nkeloa sebaka.

2. mabapi le phumano e matla ea inverter

Teko e matla e ka etsoa feela kamora hore liteko tsohle tsa tuli li tloaelehe. Ka lehlakoreng le leng, pele o kenya motlakase ho inverter, ho hlokahala hore o hlahlobe hore na motlakase oa ho kenya le ho lekanya boemo ba voltage ea inverter li ts'oana joang; ka lehlakoreng le leng, ho hlokahala hore u hlahlobe hore na sesebelisoa se seng le se seng se lokolohile le hore na khokahano e tloaelehile. Ka mor'a hore inverter e sebelisoe, qala ho bona phoso, 'me u fumane hore na sesosa le mofuta oa phoso ke eng ho latela khoutu ea phoso; bobeli, hlahloba hore na mekhahlelo e behiloeng le litekanyetso tse lekantsoeng tsa mojaro lia tšoana. Haeba inverter e sa hokahane le mojaro ebile e le ts'ebetsong e se nang mojaro, ka kopo lekanya hore na motlakase o tsoang ka terata tse tharo o lumellana joang.
