High voltage soft start state cabinet inonyanya kukodzera (3 ~ 10kV) squirrel cage asynchronous motor start and stop control and protection. Iyo yemhando yepamusoro anti-parallel thyristor zvikamu uye zvemagetsi zvigadziriso zvemagetsi zvakabatana pakati peiyo stator mhepo yeakakwira voltage mota uye magetsi ekupa. Kana mota yatanga, zvinoenderana nemumwe mutemo (senge inogara iripo kana mhepo inotsvedza) kudzora hove dzekufambisa dzeiyo interproduct chubhu, uye ramba uchichinja mapindiro eiyo stator yekupedzisira boka remota kubva pakumanikidzwa kuenda kuzere kumanikidza, mushure mekutanga. inopedzwa, iyo bypass contactor inodhirowa. Iine basa rekudzivirira kukanganisa senge-over-cut, short-phase kutanga, peak overcurrent, etc. Kuishandisa kunogona kudzivirira zvinokuvadza zvinokonzerwa nemotokari yakawandisa inotanga ikozvino kune girasi remagetsi, uye inogona kazhinji kushandisa high-power motor. pasi pesimba shoma remagetsi grid uye kuwedzera hupenyu hwayo hwesevhisi. Pamusoro pezvo, High voltage soft start state cabinet inewo "soft stop" basa, kana yakamira yakapfava, motor stator winding voltage inodzikiswa zvakanaka, nekudaro kudzivirira kumira kwechimbichimbi kwemidziyo, iyo inobatsira pombi (inogona kudzivirira. mhedzisiro yesando yemvura) kana bhandi rekutakura.
1. Saizi duku uye mabasa akazara
Iyo kabati yemapuranga inobatanidza iyo yakakwirira-voltage solid-state yakapfava-yekutanga kabati, yakakwira-voltage switch kabati, uye bypass kabati mune yakasanganiswa kabati. Idiki muhukuru. Kuenzaniswa neyakasiyana yakakwira-voltage switch kabati uye kabati yekudzidzisa,
Nzvimbo yekutanga kabhineti yakaderedzwa nehafu, uye zvakare ine mabasa ekunyorova kutanga, kunyorova kumira, switch kabati uye bypass cabinet.
2. Ikozvino yekutanga idiki uye simba rekuchengetedza simba rakakosha
Iyo yepakati- uye yakakwirira-voltage switch solid-state yakapfava-yekutanga yakasanganiswa kabati inogadzirisa voltage nekuchinja conduction angle ye thyristor, pasina kurasikirwa kwesimba uye kutanga ikozvino.
Diki, 2.5 ~ 3.5 nguva yakatarwa ikozvino.
3. Kukwanisa kwakasimba kunopesana nekupindira, kushandiswa kune zvakasiyana-siyana zvekushandisa
Iyi kabhineti yakagadzirirwa neyakasiyana-yekudzivirira-capacitance absorption circuit, iyo ine yakasimba anti-kupindira kuita. Kuita kwechigadzirwa kwakagadzikana, hakukanganiswe neambient tembiricha uye nzvimbo, uye inogona kutangwa kazhinji.
4. Mabasa akazara ekudzivirira uye kuchengetedzwa kwepamusoro
Iyo ine mabasa ekudzivirira kukanganisa senge kuwandisa, kurasikirwa kwechikamu, uye kutanga peak overcurrent. Iwo ekutanga maparamita anosarudzika, anochinjika uye anodzoreka.
5. Kuchengetedza-pasina, kuchengetedza mari
Iyo yekuchengetedza-yemahara dhizaini inoderedza tambo dze wiring dzepamusoro-voltage switch makabati uye akapfava-kutanga makabati. Hapana kumwe kuchengetedza kunodiwa mushure mekushandiswa, izvo zvinogona kuchengetedza mari yakawanda mumitengo yekuchengetedza.
