Khabinete ea boemo bo phahameng ea motlakase e phahameng e loketse haholo (3 ~ 10kV) squirrel cage asynchronous motor start and stop control and protection. Likarolo tsa boleng bo phahameng ba anti-parallel thyristor le lisebelisoa tsa taolo ea elektronike li kopantsoe pakeng tsa stator winding ea motlakase o phahameng oa motlakase le matla a matla. Ha motlakase o qala, ho ea ka molao o itseng (joaloka moepa o sa khaotseng oa hona joale kapa oa motlakase) laola tlhapi ea conduction ea tube ea interproduct, 'me u tsoele pele ho fetola tlhahiso ea sehlopha sa ho qetela sa stator ho tloha khatellong ho ea ho khatello e feletseng, ka mor'a ho qala. e phethiloe, ho huloa "bypass contactor".

1. Boholo bo bonyenyane le mesebetsi e feletseng
Khabinete ea lepolanka e kopanya khabinete ea boemo bo phahameng ba boemo bo phahameng ba boemo bo bonolo ba ho qala, khabinete ea switch ea motlakase o phahameng, le khabinete ea bypass ho khabinete e kopaneng. E nyane ka boholo. Ha ho bapisoa le khabinete e arohaneng ea li-voltage tse phahameng le khabinete ea ho ruta,
Sebaka sa khabinete sa ho qala se fokotsehile ka halofo, hape se na le mesebetsi ea ho qala ha bonolo, ho emisa ha bonolo, switch cabinet le bypass cabinet.
2. Nako ea ho qala e nyane mme phello ea ho boloka matla e bohlokoa
Khabinete e kopantsoeng ea matla a mahareng le a phahameng a matla a matla a boemo bo bonolo a qalang e fetola motlakase ka ho fetola angle conduction ea thyristor, ntle le tahlehelo ea matla le ho qala hona joale.

3. Bokhoni bo matla ba ho thibela tšitiso, bo ikamahanyang le maemo a fapaneng a ts'ebeliso
Khabinete ena e entsoe ka potoloho e khethehileng ea ho hanyetsa-capacitance absorption, e nang le ts'ebetso e matla ea ho thibela tšitiso. Ts'ebetso ea sehlahisoa e tsitsitse, ha e amehe ke mocheso oa tikoloho le sebaka sa sebaka, 'me e ka qalisoa khafetsa.
4. Mesebetsi e feletseng ea tšireletso le tšireletso e phahameng
E na le ts'ebetso ea ts'ireletso ea liphoso joalo ka moroalo o mongata, tahlehelo ea karolo, le ho qala peak overcurrent. Mekhahlelo ea ho qala ke ea boikhethelo, e ka fetoloa ebile e khona ho laola.
5. Ho boloka, ho boloka litšenyehelo
