Chate ea Khetho e Felletseng ea Schneider: Tataiso ea Tšireletso ea Mohato ka Mohato
Ho khetha sebaka se nepahetseng sa Schneider overload relay ho bohlokoa bakeng sa ho sireletsa lienjineri, ho fokotsa nako ea ho theoha, le ho netefatsa hore ho latela litekanyetso tsa polokeho. Lichate tsa semmuso tsa khetho tsa Schneider li nolofatsa ts'ebetso ena, 'me ka ho li kopanya le ho fumana chelete e tšepahalang ho Simply Buy, u tla boloka ho nepahala le ho ts'epahala.
Tšireletso e nepahetseng bakeng sa Motors ea hau
Tšireletso ea makoloi ha ho mohla e lekanang ka botlalo. Enjene e 'ngoe le e' ngoe e na le litlhoko tse ikhethang tsa mojaro, maemo a ts'ebetso le litlhoko tsa ts'ebetso. Ke ka lebaka leo ho khetha sebaka se nepahetseng sa overload ho bohlokoa bakeng sa ho netefatsa polokeho, ho thibela ho hloleha ho theko e boima, le ho ntlafatsa bophelo ba makoloi.
Schneider Electric e ts'ehetsa ts'ebetso ena ka litšupiso tse qaqileng, joalo ka lethathamo la lintlha tse fetisang litaba tsa Schneider le chate ea khetho ea mefuta e fetang ea Schneider ea PDF. Lisebelisoa tsena li thusa bareki le baenjiniere ho tsamaisana hantle le litlhoko tsa kopo ea bona, ekaba ba khetha li-relay tsa compact thermal kapa litharollo tse tsoetseng pele tsa elektroniki.
Ke Hobane'ng ha Khetho e Loketseng ea Relay e Bohlokoa
The overload relay ke mohala oa pele oa tšireletso lipakeng tsa enjene ea hau le tšenyo. Khetho e nepahetseng e na le melemo e mengata:
- E thibela ho Chesoa ha Likoloi: Meroalo e mengata ke e 'ngoe ea lisosa tse ka sehloohong tsa ho hloleha ha makoloi. Maeto a nepahetseng a relay pele tšenyo e etsahala.
- Qoba Nako ea Phomolo e sa Hlokehang: Li-relay tse boholo bo nepahetseng li fokotsa ho khoptjoa ho sitisang tlhahiso ho sa hlokahale.
- E Kopana le Melao ea Tšireletso ea Motlakase: Khokahano e nepahetseng ea li-relay le li-SCPD (lisebelisoa tse sireletsang potoloho e khuts'oane) li netefatsa ho latela NEC / IEC.
- E Ntlafatsa Bophelo bo Bolelele ba Lisebelisoa: Tšireletso e hokahaneng le motor Full Load Amps (FLA) e eketsa bophelo ba tšebeletso ea likoloi.
Ka lehlakoreng le leng, ho khetha li-relay tse fosahetseng ho ka baka ho hloleha ha enjene pele ho nako, litšenyehelo tse phahameng tsa ho nchafatsa, kapa ho emisa tlhahiso ho sa hlokahale.
Ho Utloisisa Chate ea Khetho ea Schneider Overload Relay
Chate e hlakileng ea Schneider ea khetho ea mefuta e mengata ea li-relay e nolofalletsa mokhoa oa ho khetha. Chate ena e thathamisa litšobotsi tsa enjene, mefuta ea li-relay tse ngata, le tšebelisano ea ts'ebeliso ho thusa basebelisi ho etsa khetho e nepahetseng.
Li-parameter tsa bohlokoa ka ho fetisisa chate li kenyelletsa:
- Li-Amps tsa Moroalo o Tletseng oa Enjene (FLA): Boleng ba bohlokoa bo sebelisitsoeng ho boholo bo tsamaisana hantle.
- Matla a Motlakase (HP/kW): E etsa qeto ea ts'ireletso e tsamaellanang le meroalo e ipapisitseng le boima ba moroalo.
- Motlakase oa Motlakase: E netefatsa hore relay e loketse litekanyetso tsa phepelo ho sistimi ea hau.
- Sehlopha sa Leeto - Li-relay tsa Schneider li fumaneha ho Sehlopha sa 10, 20, kapa 30 (nako ka metsotsoana ho tsamaea ka 600% ea hajoale).
- Mofuta oa ho Qala: Khetho e fapana bakeng sa Direct-On-Line, Star-Delta, kapa mekhoa e meng ea ho qala.
- Mofuta oa Relay: Likhetho li kenyelletsa mocheso (joalo ka TeSys LRD) bakeng sa likopo tse tloaelehileng kapa elektronike (joaloka TeSys Giga Tšireletso Relays) bakeng sa tlhahlobo e tsoetseng pele.
Litšupiso tsena, hammoho le chate ea khetho ea li-relay tse ngata tsa Schneider PDF, li fana ka mokhoa o hlophisitsoeng oa khetho e nepahetseng ea sehlahisoa.
Mohato ka Mohato oa ho Khetha
Mohato oa 1: Etsa qeto ea hore na li-Amps tsa Moroalo o felletseng oa Motor (FLA)
Sheba letlapa la lebitso la enjene bakeng sa FLA. Li-relay tsa Schneider li boholo ka mekhahlelo ea amp, eseng matla a lipere feela. Mohlala: enjene ea 10 HP, 400V e kanna ea ba le ~ 14.8A FLA.
Mohato oa 2: Tseba Litšobotsi tsa Likoloi
Ela hloko lintlha tsa motlakase tsa HP/kW, motlakase o sebetsang, le mofuta oa ts'ebeliso (mosebetsi oa kamehla, oa nakoana, torque e qalang, joalo-joalo). Lintlha tsena li fokotsa likhetho.
Mohato oa 3: Khetha Mofuta oa Relay
E latelang, khetha ho li-relay tse peli tse latelang:
- Li-relay tsa mocheso (joalo ka Schneider LRD li-relay tse ngata haholo) li loketse lits'ebetso tse tloaelehileng moo bonolo le ho tšepahala e leng lintho tse tlang pele. Likhetho tse tsebahalang li kenyelletsa Schneider Electric LRD14 overload relay, e fuoeng li-motors tsa 7-10 A.
- Li-relay tsa elektronike (joalo ka TeSys Giga Tšireletso Relays) fana ka ho nepahala ho holimo, kutlo ea tahlehelo ea karolo, le tlhahlobo ea hole, e leng se etsang hore li tšoanelehe bakeng sa lits'ebetso tsa bohlokoa.
Mohato oa 4: Sheba Chate
Ha u se u tseba li-amps tse felletseng tsa enjene (FLA) le lintlha tse ling tsa bohlokoa, sebelisa chate ea khetho ea Schneider's overload relay ho tsamaisana le relay e nepahetseng. Litšupiso tsa chate li bonts'a FLA ea hau ka mefuta e loketseng ea relay le sehlopha sa maeto.
Ka mohlala:
- Enjene e lekantsoeng 7-10A hangata e bitsa Schneider TeSys LRD14 bimetallic overload relay, Sehlopha sa 20.
- Bakeng sa likarolo tsa ts'ireletso tse nepahetseng kapa tse tsoetseng pele, u kanna ua khetha Schneider LR9D solid-state relay.
- Bakeng sa taolo e rarahaneng ea makoloi, Schneider's TeSys T Motor Management System e fana ka tlhaiso-leseling, puisano le ts'ireletso e boletsoeng esale pele.
Mohato oa 5: Nahana ka Lintlha Tse Eketsehileng
Li-relay tsa morao-rao li fetela ka nģ'ane ho ts'ireletso ea boima bo feteletseng. Lekola:
- Phase tahlehelo le phase imbalance sensitivity.
- Seta botjha mekhoa (ka letsoho kapa othomathike).
- Mabitso a thusang bakeng sa pontšo e hole.
- Likhetho tsa ho kopanya le tse qalang joalo ka TeSys GV2 Motor Starter kapa li-unit tsa matla a phahameng joalo ka TeSys Giga Contactors.
Liphoso Tse Tloaelehileng Tsa ho Qoba Nakong ea Khetho
Le bareki ba nang le boiphihlelo ba ka etsa liphoso ha ba khetha li-relay tsa overload. Likotsi tse ling li kenyelletsa:
- Ho nyenyefatsa kapa ho fetelletsa leqhubu - ka bobeli li fella ka tšireletso e sa lekaneng kapa ho khoptjoa ho sa hlokahaleng.
- Ho iphapanyetsa matšeliso a mocheso a tikoloho - li-relay li ka hloka phetoho haeba li kentsoe libakeng tse feteletseng.
- Ho tsamaellana le contactor - li-relay li tlameha ho ikamahanya le mefuta ea likhokahano ho netefatsa khokahanyo e se nang moeli, joalo ka li-relay tsa LRD le li-contact tsa TeSys D.
- Ho Tlosa Litlhaloso tsa Sehlopha sa Leeto: Relay ea Sehlopha sa 10 e ka 'na ea e-ba khathatso-leeto holim'a meroalo e phahameng ea inertia; Sehlopha sa 20 se loketse haholoanyane.
Ho qoba liphoso tsena ho netefatsa ts'ireletso e nepahetseng ea makoloi le ts'epo ea sistimi.
