Nheyo yeKushanda kweVatangi Vezvinyoro (Tsananguro yeUnyanzvi yeKutaurirana kweTechnical yeKutengeserana kweKunze)
A nyoro yekutanga (ChiSpanish: arrancador suave) mudziyo wekudzora mota dzeAC induction, dzine basa guru riri kutanga nekumira zvishoma nekudzora zvakanaka voltage yemotaInodzivisa kukuvara kwemamota, magridi emagetsi, uye michina yekutakura zvinhu inokonzerwa nemagetsi akawandisa panguva yekutanga zvakananga, uye inoshandiswa zvakanyanya mu Midziyo yeMaindasitiri zvakaita semapombi, mafeni, macompressor, uye maconveyor.
Nheyo Yekushanda Yepakati: Kudzora Voltage Ramp (Nzira Yakajairika)
Chikamu chikuru che Nyowani Yekutanga iTriackana module ye thyristor inopesana neyakafanana(mapoka maviri e thyristors akabatana mu reverse parallel kuti awane bidirectional conduction ye AC power). Pfungwa dzayo dzekushanda dzakavakirwa pa "voltage gradient", nemaitiro chaiwo seanotevera:
- Danho rekutanga:
- Kana mota yakabatana ne Magetsi, starter yakapfava inowedzera zvishoma nezvishoma kona yekufambisa (duty cycle) yethyristor kuburikidza ne electronic control circuit, kuitira kuti voltage inoshandiswa kumota stator winding inokwira kubva pa0 kusvika pa rated voltage (voltage rise curve inogona kuiswa, senge linear kana exponential).
- Torque yemota inoenderana neskweya yevoltage (T∝U²). Kana voltage ikakwira zvishoma nezvishoma, torque inowedzerawo zvakanaka, uye kumhanya kwemota kunowedzera zvishoma nezvishoma kubva pakuzorora kusvika pakumhanya kwakarongwa (kazhinji masekondi 3-30, kuchigadziriswa zvichienderana nemutoro).
- Kana tichienzanisa nekutangira zvakananga (uko voltage inoiswa ipapo ipapo pamutengo wakarongwa, uye simba rekutanga rinogona kusvika ka5-8 pane simba rakarongwa), simba rekutanga rakapfava rinogona kuganhurira simba rekutanga kusvika ka1.5-4 pane simba rakarongwa, zvichideredza zvakanyanya simba remagetsi.
- Danho rekushanda:
- Kana mota yasvika pakumhanya kwakatarwa, thyristor yestarter yakapfava inenge yave kuita basa rayo zvizere (yakaenzana neshort circuit), uye mota yacho yakabatana zvakananga ne power grid kuti ishande. Panguva ino, starter yakapfava haina simba rakawanda, zvichidzivirira kupisa kwenguva refu.
- Mamwe mamodheru emhando yepamusoro ane chinobata che bypass. Mushure mekunge chatanga, chinobata chinodhonza kuti chitsive thyristor kuti ifambise, zvichiwedzera kuvimbika uye kuderedza kurasikirwa.
- Chikamu Chekumisa:
- Mushure mekugamuchira chiratidzo chekumira, starter yakapfava inoderedza zvishoma nezvishoma angle yekufambisa yethyristor, zvichiita kuti voltage yemota iderere zvishoma nezvishoma, uye kumhanya kunoderera zvakanaka kusvika pakumira (Chinomira NyoroIzvi zvinodzivirira kukanganiswa kwekusashanda zvakanaka kwemutoro kunokonzerwa nekumira kamwe kamwe (sekunge kukanganiswa kwemvura nehammer yemapombi uye kutsvedza kwezvinhu zvemaconveyor).
Zvinhu Zvikuru zveTechnical (Zvakagadzirirwa Kutaurirana nezveTechnical Parameter yekutengeserana kwekunze)
- Kutanga Muganho Wazvino: Nekuisa chiyero chepamusoro chemagetsi ekutanga, zvinodzivirira kudonha kwemagetsi egrid uye zvinodzivirira kutenderera kwemota kubva pakukanganiswa kwemagetsi kwakakwira.
- Kugadziriswa kweVoltage Ramp: Nguva yekukwira kwevoltage (masekondi 0-30) inogona kugadziriswa kuti ienderane nemaitiro akasiyana emutoro (semuenzaniso, nguva refu yekukwira inodiwa kuti mutoro unorema utange).
- Mabasa ekudzivirira: Inobatanidza Dziviriro Yekuremerwa Zvakawandisa, dziviriro yekurasikirwa nechikamu, dziviriro ye overvoltage/undervoltage, dziviriro yekupisa zvakanyanya, nezvimwewo. Inokurumidza kudzima magetsi nemaalamu kana paine zvikanganiso.
- Mhando dzeMotokari Dzinoshanda: Yakakodzera chete mamota eAC induction ane maphase matatu (mhando yesquirrel-cage), kwete mamota eDC, mamota anoenderana, kana mamota ewound-rotor.
- Musiyano kubva kumaInverters (VFD)(Mubvunzo weKukurukurirana Kwekutengeserana Kwekunze):
| Chinhu Chekuenzanisa | Nyowani Yekutanga | Kutyaira Kwenguva Inoshandiswa Nenguva Dzese (VFD) |
| Basa Guru | Kutanga/kumisa zvinyoro nyoro chete | Kutanga zvinyoro nyoro + kudzorwa kwekumhanya + kudzora kuchengetedza simba |
| Nheyo yekushanda | Kudzora kwemagetsi (nguva dzose) | Kudzora voltage + frequency (V/F control) |
| Kushandiswa kweSimba reKushanda | Hapana kushandiswa kwesimba mushure mekutanga | Kushandiswa kwesimba kwenguva refu (anenge 3-5%) |
| Mutengo | Pasi (inenge 1/3-1/2 yeVFD) | Yepamusoro |
| Mamiriro Ezvinhu Anoshanda | Midziyo isina mitemo yekumhanya (mapombi, mafeni, macompressor) | Midziyo inoda kudzorwa kwekumhanya (maconveyor, maturusi emuchina, maelevator) |
Maitiro Akajairika Ekushandisa (Anoenderana Nekutaurirana Kwebhizinesi Rekunze Kwekutengeserana)
- Mapombi/Mafeni: Dzivisa kushanduka kwegrid remagetsi kunokonzerwa nekukanganiswa kwemagetsi ekutanga, uye deredza mhedzisiro yehammer yemvura/kukanganiswa kwemhepo panguva yekumira;
- Macompressor/Air Compressors: Deredza mutoro wemakanika panguva yekutanga uye chengetedza zvinhu zvakaita semasilinda nemapistoni;
- MaConveyor: Dzivirira kuti zvinhu zvitsvedzerere panguva yekutanga uye kudzivirira kubhureka zvakanaka panguva yekumira;
- Zvishandiso zveMuchina/Mitoro yePombi: Yakakodzera michina isingade kudzorwa kwekumhanya asi inonzwa kukanganiswa kwekutanga.
Kana muchida kugadzirisa ma technical parameters chaiwo (akadai se voltage range, current rating, kana control method ye some model of soft starter) yekutaurirana kwekutengeserana kwekunze (semuenzaniso, email translation, parameter dudziro), ndapota ipai zvirimo kuti muwane rumwe rubatsiro!
