Noker Ac Drives 10kv 1000kW Medium Voltage Vfd Motor Soft Starter
Medium voltage motor motor soft starter ke mofuta o mocha oa ac motor o qalang sesebelisoa ho nkela sebaka se tloaelehileng sa star-delta starter, self coupling voltage-drop starter le magnetic control-drop starter.Nako ea ho qala e ka ba tlase ho feta makhetlo a ka bang 3 e lekantsoeng hona joale mme e ka qala khafetsa le khafetsa.
Transformer ea hona joale e lemoha hona joale ea mekhahlelo e meraro 'me e sebelisetsoa ho fokotsa le ho sireletsa hona joale.Voltage transformer e lemoha matla a mekhahlelo e meraro.E sebelisetsoa ho lemoha le ho sireletsa motlakase bakeng sa overvoltage le undervoltage.Molaoli oa MCU o laola thyristor bakeng sa taolo ea phase Angle trigger, ka nako e ts'oanang e fokotsa motlakase ho enjene, e fokotsa lebelo la ho qala, mme e qala enjene hantle ho fihlela koloi e matha ka lebelo le felletseng.Kamora hore enjene e sebetse ka lebelo le felletseng, fetohela ho "bypass contactor".Sesebelisoa sa motlakase se mahareng se ntse se tsoela pele ho bona liparamente tsa enjene ho sireletsa koloi.Sesebelisoa sa motlakase se phahameng sa motlakase se ka fokotsa motlakase oa motlakase le ho fokotsa tšusumetso ho grid ea matla le koloi ka boeona.Ka nako e ts'oanang, e boetse e fokotsa tšusumetso ea mochine mochineng oa ho kenya mochine, e lelefatsa bophelo ba tšebeletso ea sesebelisoa le ho fokotsa ho hlōleha ha motlakase.Khiboto&mojule ea ponts'o e bonts'a liparamente tsohle le data ea boemo ba mochini o qalang o bonolo.
1. E sa hloke tlhokomelo: Thyristor ke sesebelisoa sa motlakase se se nang mabitso.Ho fapana le mefuta e meng ea lihlahisoa tse hlokang tlhokomelo khafetsa ho mokelikeli le likarolo tse ling, e fetola phahamiso ea mochini hore e be bophelo ba ts'ebeletso ea likarolo tsa elektroniki, ka hona ha e hloke tlhokomelo kamora ho sebetsa ka lilemo tse ngata.
2. Ho kenya le ts'ebetso e bonolo: Sistimi e felletseng ea matla a mahareng a motlakase o bonolo bakeng sa ho laola le ho sireletsa ho qala ha enjene.E ka kenya ts'ebetsong feela ka mohala oa motlakase le mohala o hokahaneng.Sistimi eohle e ka lekoa ka motlakase tlasa voltage e tlase pele e sebetsa ka matla a phahameng.
3. Backup: Starter e na le lisebelisoa tse nang le "vacuum contactor" tse ka sebelisoang ho qala motlakase ka ho toba ka hare. Haeba e hlōleha, mochine oa vacuum o ka sebelisoa ho qala motlakase ka ho toba ho netefatsa hore tlhahiso e tsoela pele.
4. Medium voltage motor soft starter e tla e na le mochine o thibelang motlakase ka lebaka la ho tšaba ho kena mochine o phahameng oa motlakase sebakeng sa motlakase.
5. Mokhoa o tsoetseng pele oa phetisetso ea fiber optical o hlokomela ho lemoha ho susumetsang ha thyristor e phahameng ea voltage le ho itšehla thajana pakeng tsa loops ea taolo ea LV.
6. DSP microcontroller e sebelisetsoa ho etsa taolo ea bohareng e leng nako ea sebele le e phahameng e nang le ts'epo e phahameng le botsitso bo babatsehang.
7. Sistimi ea ho bonts'a LCD / touch screen ka Sechaena le Senyesemane e nang le sebopeho sa ts'ebetso se bonolo sa motho.
8. Boema-kepe ba puisano ba RS-485 bo ka sebelisoa ho buisana le k'homphieutha e ka holimo kapa setsi sa taolo se bohareng.
