Noker Ac Drives 10kv 1000kW Medium Voltage Vfd Motor Soft Starter
Medium voltage motor motor soft starter ndiyo itsva ac motor start device kutsiva yakajairwa nyeredzi-delta starter, self-coupling voltage-drop starter uye magnetic control voltage-drop starter.Iyo yekutanga ikozvino inogona kuve yakaderera kupfuura kanenge ka3 yakayerwa ikozvino uye inogona kutanga yadzokororwa uye nekuenderera.
Ikozvino transformer inoona matatu-chikamu ikozvino uye inoshandiswa kune ikozvino kumisa uye kudzivirira.Voltage transformer inoona matatu-phase voltage.Iyo inoshandiswa kune yakakonzeresa nhanho yekuona uye kuchengetedzwa kwevoltage kune overvoltage uye undervoltage.Iyo MCU controller inodzora iyo thyristor yechikamu Angle trigger control, panguva imwe chete ichidzikisa voltage pamota, inodzikamisa yekutanga ikozvino, uye inonyatso tanga mota kusvika mota ichimhanya yakazara.Mushure mekunge mota ichimhanya nekumhanya kwakazara, chinja kune bypass contactor.Iyo yepakati voltage mota yakapfava yekutanga inoenderera nekuona maparamendi emota kudzivirira mota.Iyo yakakwira voltage mota yakapfava starter inogona kuderedza inrush ikozvino yemota uye kuderedza kukanganiswa kwemagetsi grid uye mota pachayo.Panguva imwecheteyo, zvakare inoderedza kukanganiswa kwemakanika pane mota yekurodha mudziyo, inowedzera hupenyu hwesevhisi yechishandiso uye inoderedza kutadza kwemota.Iyo keyboard & kuratidza module inoratidza ese ma paramita uye mamiriro data eiyo mota yakapfava yekutanga.
1. Yemahara yekuchengetedza: Thyristor mudziyo wemagetsi usina vanobatika.Yakasiyana nemamwe marudzi ezvigadzirwa zvinoda kugara uchigadziriswa pamvura uye zvikamu nezvimwe, inoshandura kusimudza kwemakanika kuita hupenyu hwesevhisi yezvikamu zvemagetsi, saka haidi gadziriso mushure mekushanda kwemakore mazhinji.
2. Kuisa nyore uye kushanda: Medium voltage motor soft starter yakakwana system yekudzora uye kudzivirira kutanga kwemotokari.Inogona kuisa mukushanda chete netambo yemagetsi uye mutsara wemota yakabatana.Iyo yese system inogona kuongororwa magetsi pasi pe low voltage isati yashanda nehigh voltage.
3. Backup: The starter inouya yakashongedzerwa ne-vacuum contactor iyo inogona kushandiswa kutanga motokari zvakananga mukati mukati.Kana ikakundikana, vacuum contactor inogona kushandiswa kutanga motokari zvakananga kuti ive nechokwadi chekuenderera kwekugadzirwa.
4. Medium voltage motor motor soft starter inouya yakashongedzerwa neelectromagnetic blocking device nekutya kupinda mumudziyo wemagetsi wakakwira munzvimbo ine magetsi.
5. Advanced optical fiber transmission technique inoziva kukonzeresa kuona kwehigh voltage thyristor uye kuparadzaniswa pakati peLV control loops.
6. DSP microcontroller inoshandiswa kuita pakati pekutonga iyo inguva-yechokwadi uye yakakwirira inoshanda nekuvimbika kwepamusoro uye kugadzikana kwakanakisisa.
7. LCD / touch screen display system mumutauro weChinese neChirungu nekushanda kwevanhu.
8. RS-485 chiteshi chekukurukurirana chinogona kushandiswa kutaurirana nekombuta yepamusoro kana centralized control centre.
