Mokhatlo le Tšebeliso ea Phepelo ea Matla a ho Fetola, Bahokahanyi, Li-Frequency Inverters, le Relays

Lits'ebetsong tsa sejoale-joale tsa motlakase, lisebelisoa tsa motlakase (SMPS), likhokahano, li-inverters tsa maqhubu, le ho fetisa karolo e 'ngoe le e 'ngoe ea bohlokoa, mme ts'ebetso ea bona ea tšebelisano-mmoho e nolofalletsa taolo e bonolo le e sebetsang ea lisebelisoa tsa motlakase. Sengoliloeng sena se tla shebana le likamano lipakeng tsa lisebelisoa tsena le mekhoa ea tsona ea ts'ebeliso.

I. Kakaretso ea Sesebelisoa

1. Phepelo ea Motlakase (SMPS)
   Phepelo ea motlakase ke sesebelisoa se sebetsang hantle sa ho fetola matla se laolang le ho tsitsisa motlakase o tsoang ka ho chencha likarolo tsa elektroniki ka potlako (joalo ka transistors). Ha ho bapisoa le lisebelisoa tsa motlakase tse tloaelehileng, lisebelisoa tsa motlakase li fana ka ts'ebetso e phahameng le boholo bo nyane le boima ba 'mele. Molao-motheo oa ts'ebetso oa phepelo ea motlakase o kenyelletsa ho laola phetisetso ea matla a phepelo ea motlakase ka ts'ebetso e potlakileng ea phepelo ea motlakase, ka hona ho fihlela phetoho le botsitso.

   

2. Contactor
   A contactor ke othomathike electromagnetic fapoha loketseng bakeng sa ho hokela khafetsa kapa hakolla AC le lipotoloho DC le lipotoloho tse khōlō-bokgoni laola ho tloha hole. Ha e lumelle feela ts'ebetso ea othomathike e hole le mesebetsi ea ts'ireletso ea tokollo ea undervoltage empa e boetse e ithorisa ka matla a ho laola, ho ts'epahala, ts'ebetso e sebetsang hantle le bophelo bo bolelele ba ts'ebeletso.

   
   
   

3. Frequency Inverter
   Frequency inverter ke sesebelisoa se laolang lebelo la ts'ebetso ea enjene ea motlakase ka ho fetola maqhubu a phepelo ea motlakase, haholo-holo e loketseng lits'ebetso tse hlokang taolo e nepahetseng ea lebelo le torque. Frequency inverter e qala ho fetolela AC ho DC, ebe e sebelisa potoloho ea inverter ho fetolela DC ho AC ka maqhubu a feto-fetohang, ka hona e khanna koloi ea motlakase.

4. Relay
   Relay ke sesebelisoa sa taolo ea motlakase se bakang phetoho e reriloeng esale pele ea palo e laoloang potolohong ea tlhahiso ea motlakase ha phetoho ea bongata ba tlhahiso (stimulus) e fihlela litlhoko tse boletsoeng. E theha kamano e kopanetsoeng pakeng tsa tsamaiso ea taolo (potoloho ea ho kenya) le tsamaiso e laoloang (potoloho ea potoloho).

   

II. Tlhahlobo ea Mokhatlo

1. Fetola Phepelo ea Matla le Contactor
   Motlakase oa ho fetola matla o fana ka matla a tsitsitseng a DC bakeng sa motho ea kopanyang, ho etsa bonnete ba ho kopanela le ho lokolloa ha contactor. Litsamaisong tsa taolo ea motlakase, phepelo ea motlakase e fetohang hangata e sebetsa e le phepelo ea mantlha ea motlakase, e fanang ka matla a tsitsitseng a motlakase tsamaisong eohle.

2. Contactor le Frequency Inverter
   The contactor phetha karolo ea ho hokela kapa hakolla phepelo ea motlakase ho enjene ea motlakase ka maqhubu a tsamaiso inverter taolo. Ha frequency inverter e hloka ho qala kapa ho emisa enjene ea motlakase, e laola boitlamo le tokollo ea sehokelo ho fihlela khokahanyo ea phepelo ea motlakase kapa ho khaoha. Ho ekelletsa moo, contactor ka sireletsa inverter maqhubu ho tloha liphoso tse kang motor overload.

3. Frequency Inverter le Relay
   Hangata li-inverters tsa motlakase li hokahanngoa le ho laoloa le lisebelisoa tse ling tsa motlakase ka li-relay. Mohlala, li-relay li ka laola ho buloa le ho koaloa ha li-circuits tse amanang nakong ea ho qala le ho koala lits'ebetso tsa frequency inverter. Ntle le moo, ha frequency inverter e bona liphoso tse kang motor overload kapa overcurrent, e ka fana ka matšoao a alamo kapa ea khaola phepelo ea motlakase ka li-relay.

4. Kopo e Kopanetsoeng
   Lits'ebetsong tse sebetsang, phepelo ea motlakase e fetohang, likhokahano, li-frequency inverters, le li-relay hangata li sebelisoa hammoho ho theha sistimi e felletseng ea taolo ea motlakase. Mohlala, lits'ebetsong tsa phepelo ea metsi khafetsa, li-PLC li ka laola li-inverters tsa maqhubu ho fihlela ts'ebetso ea lipompo tse fapaneng, ha li-contact le li-relay li sebelisoa bakeng sa khokahano ea phepelo ea motlakase le ho khaoha, ts'ebetso ea alamo ea phoso, le tse ling.

III. Mekhoa ea Tšebeliso

1. Tšebeliso ea Phepelo ea Matla a Switching

   • Khetha mofuta o nepahetseng oa phepelo ea motlakase le litlhaloso tse ipapisitseng le litlhoko tsa sistimi ea taolo ea motlakase.
   • Hokela phepelo ea motlakase ho marang-rang a matla 'me u netefatse hore motlakase oa eona oa ho kenya le oa hona joale o lumellana le litlhaloso.
   • Fetola matla a motlakase le a teng a phepelo ea motlakase ha ho hlokahala ho fihlela litlhoko tsa phepelo ea motlakase ea lisebelisoa tsa motlakase.

2. Tšebeliso ea Contactor

   • Khetha mofuta o nepahetseng oa li-contact le litlhaloso tse thehiloeng ho litlhoko tsa tsamaiso ea motlakase.
   • Kopanya coil ea khokahanyo ho potoloho ea taolo 'me u netefatse hore motlakase oa eona o sebetsang le hona joale o lumellana le litlhaloso.
   • Hokela mabitso a ka sehloohong a contactor le mabitso a thusang ha ho hlokahala ho finyella kgokelo ya potoloho le khaollo.

3. Tšebeliso ea Frequency Inverter

   • Khetha mofuta o nepahetseng oa frequency inverter le litlhaloso tse ipapisitseng le mofuta oa enjene ea motlakase le litlhoko tsa mojaro.
   • Hokela pheletso e kenang ea frequency inverter ho grid ea matla le pheletso e tsoang ho enjene ea motlakase.
   • Seta liparamente tsa inverter ea maqhubu ha ho hlokahala, joalo ka maqhubu a tlhahiso, mokhoa oa ho qala, le lits'ebetso tsa ts'ireletso.
   • Laola ho qala, ho emisa, le taolo ea lebelo ea frequency inverter ka phanele ea ts'ebetso kapa sebopeho sa puisano se hole.

4. Tšebeliso ea Relay

   • Khetha mofuta o loketseng oa relay le litlhaloso ho latela litlhoko tsa sistimi ea taolo ea motlakase.
   • Kopanya coil ea relay ho potoloho ea taolo 'me u netefatse hore motlakase oa eona o sebetsang le hona joale o lumellana le litlhaloso.
   • Hokela likhokahano tse bulehileng tsa relay le likhokahano tseo hangata li koaletsoeng ha ho hlokahala ho fumana taolo ea potoloho.

IV. Mehato ya tlhokomelo

1. Ha u sebelisa lisebelisoa tsa motlakase, ela hloko botsitso le ho feto-fetoha ha motlakase oa bona oa motlakase le oa hona joale ho netefatsa ts'ebetso e tloaelehileng ea lisebelisoa tsa motlakase.
2. Ha u sebelisa li-contactor, hlokomela ho senyeha le ho senyeha ha mabitso a bona, 'me u nke sebaka sa mabitso a tsofetseng hang-hang.
3. Ha u sebelisa li-inverters tsa maqhubu, ela hloko mefuta e fapaneng ea ho feto-fetoha ha maqhubu a tlhahiso ea bona le motlakase, hammoho le boemo ba moroalo oa koloi ea motlakase, ho qoba liphoso tse kang overload le overcurrent.
4. Ha u sebelisa li-relay, etsa bonnete ba ho tšepahala le bophelo ba ts'ebeletso ea mabitso a bona, 'me u nke sebaka sa li-relay tse hlōlehileng ka nako.

Ka kakaretso, lisebelisoa tsa motlakase tse fetohang, li-contactor, li-frequency inverters, le li-relay li bapala karolo e 'ngoe le e' ngoe ea bohlokoa lits'ebetsong tsa taolo ea motlakase, 'me ts'ebetso ea bona ea tšebelisano-mmoho e nolofalletsa taolo e bonolo le e sebetsang ea lisebelisoa tsa motlakase. Lits'ebetsong tse sebetsang, khetha mefuta e nepahetseng ea lisebelisoa le litlhaloso tse ipapisitseng le litlhoko tsa sistimi ea taolo ea motlakase, 'me u li sebetse le ho li boloka ka tieo ho latela mekhoa ea ts'ebeliso le litemoso.
