Ndeapi mazano makuru ekutenga ma alternator akanaka eAC

Parizvino, kushomeka kwemagetsi pasi rose kuri kuramba kuchikura. Makambani mazhinji nevanhu vanosarudza kutenga majenareta kuti vaderedze zvirambidzo pakugadzirwa uye hupenyu hwemagetsi zvinokonzerwa nekushaikwa kwemagetsi. Alternator yeAC ndeimwe yenzvimbo dzakakosha kune seti yese yejenareta. Maitiro ekusarudza alternator yakavimbika, mazano anotevera anofanira kucherechedzwa:

I. Hunhu hwemagetsi:

1. Sisitimu yekukurudzira: Padanho rino, sisitimu yekukurudzira yeAC alternator yepamusoro-soro inozvikurudzira yega, iyo inowanzo shongedzerwa ne automatic voltage regulator (AVR). Simba rekubuda kwe exciter rotor rinotumirwa ku host rotor kuburikidza ne rectifier. Mwero wekugadzirisa voltage we steady-state weAVR unonyanya kuva ≤1%. Pakati pawo, AVR yepamusoro-soro ine mabasa akawanda akadai sekushanda kwakafanana, dziviriro yakaderera yefrequency, uye kugadzirisa voltage yekunze.

2. Kudzivirira uye kufukidza: Kudzivirira kwemhando yepamusoro kwema alternator emhando yepamusoro kunowanzova kirasi "H", uye zvikamu zvayo zvese zvinomonereka zvakagadzirwa nezvinhu zvakagadzirwa zvakanyanya uye zvakanyikwa nenzira yakakosha. Alternator inomhanya munzvimbo dzakaoma kuti ipe dziviriro.

3. Kutenderedza uye kushanda kwemagetsi: Stator yealternator yemhando yepamusoro ichave yakanamirwa nemaplate esimbi anotonhorera ane simba remagineti rakakwira, mawindings ane mativi maviri, chimiro chakasimba uye kushanda zvakanaka kwekudzivirira.

4. Kupindirana kwefoni: THF (sezvakatsanangurwa neBS EN 600 34-1) isingasviki 2%. TIF (sezvakatsanangurwa neNEMA MG1-22) isingasviki 50

5. Kupindirana kweredhiyo: Midziyo isina mabhurashi yepamusoro uye AVR zvichaita kuti pave nekupindirana kushoma panguva yekutumira redhiyo. Kana zvichidikanwa, mudziyo wekuwedzera wekudzvanya RFI unogona kuiswa.

II. Hunhu hwemakanika:

Dhigirii redziviriro: Mhando dzakajairika dzemajenareta eAC epasi ndedzinoti IP21, IP22 uye IP23 (NEMA1). Kana paine chinodiwa chedziviriro chakakwira, unogona kusarudza kusimudzira nhanho yedziviriro yeIP23. Mhando yakajairika yejenareta yeAC yemugungwa iIP23, IP44, IP54. Kana uchida kuvandudza nhanho yedziviriro, senge nharaunda iri pamhenderekedzo yegungwa, unogona kushongedza jenareta yeAC nezvimwe zvinhu, zvakaita semaheater emuchadenga, mafirita emhepo, nezvimwewo.

Kushomeka kwemagetsi pasi rose kwakawedzera zvakanyanya kutengeswa kweAC alternator/generators. Mitengo yezvishongedzo zveAC generator zvakaita sema disc couplings nema rotors yakwira zvakanyanya. Kuwanikwa kwemagetsi kwakaderera. Kana uchida magetsi, unogona kutenga AC generators nekukurumidza. Mutengo weAC generators uri kuramba uchikwira!
