Fektheri e Khethehileng ea Thermal Overload Relay

CDADA, moetsi le mofani oa thepa ea thehiloeng Chaena, o fana ka mefuta e mengata ea lisebelisoa tsa motlakase tse tlaase, ho kenyelletsa le li-relay overload tsa mocheso. Sehlopha sa rona sa tekheniki se fana ka lits'ebeletso tse felletseng tsa tlhophiso ea OEM hammoho le ts'ehetso ea tekheniki ea kamora ho rekisa. Re amohela lipotso tsa hau.

Thermal Overload Relay ke eng?

A Thermal Overload Relay ke sesebelisoa se sireletsang se etselitsoeng ho tima enjene ea motlakase ha e hula motlakase o mongata nako e telele, ho etsa hore e chese ho feta tekano. Ho fapana le fuse kapa standardmohatelli oa potolohoe sebetsanang le maqhubu a phahameng hang hang (li-circuits tse khuts'oane), TOR e sebelisa tšobotsi ea nako e fapaneng. Sena se bolela hore nako ea ho khoptjoa e ea fokotseha ha lebelo la hona joale le ntse le eketseha, le bonahatsa hantle matla a mocheso oa maqhubu a motlakase.

Moko oa theknoloji ea rona o ipapisitse le molao-motheo oa bimetallic strip: litšepe tse peli tse nang le li-coefficients tse fapaneng tsa katoloso ea mocheso tse kopantsoeng hammoho. Ha e futhumatsoa ke motlakase oa motlakase, seaparo se kobeha. Haeba motlakase o feta sebaka se bolokehileng bakeng sa nako e itseng, lesela le kobeha ho lekana ho khopa likhokahano tse thusang, ho khaola matla ho khoele ea motor starter.

Mefuta le Lihlopha

Bokhoni ba rona ba tlhahiso bo kenyelletsa letoto le felletseng la mahlale a ts'ireletso a boima, a etselitsoeng litlhoko tse fapaneng tsa indasteri.

Mesebetsi ea Motheo le Tšireletso e Bohlale

Li-Relay tsa rona tsa Thermal Overload ha se li-switches tse bonolo feela; ke bahlokomeli ba bohlale ba enjene.

● Tshireletso e Felletseng: Mosebetsi oa mantlha. Ka ho kopanya hona joale ha nako e ntse e feta ( I2tI2t ), relay e sireletsa motlakase hore o se ke oa senyeha. E lumella maqhubu a nakoana a matla (ho qala enjene) ntle le ho khoptjoa empa e arabela ka ho hlaka ho moroallo o sa feleng.

● Tsireletso ea ho hloleha ha Mokhahlelo (Mokhahlelo o le Mong): Sesetemeng ea mekhahlelo e meraro, ha mohato o le mong o lahleha, enjene e hula motlakase o mongata ho mekhahlelo e 'meli e setseng ho boloka torque. Li-relay tsa rona li na le mokhoa o fapaneng (kapa oa elektroniki) o lemohang ho se leka-lekane hona ebe o tsamaea hang-hang, ho thibela enjene hore e se ke ea tima.

● Matšeliso a Mocheso: Ntho ea bohlokoa bakeng sa tikoloho ea indasteri. Li-relay tsa rona li na le thepa e lefellang bimetallic strip e hananang le liphello tsa ho fetoha ha thempereichara sebakeng. Sena se tiisa hore sebaka sa leeto se lula se nepahetse ho sa tsotellehe hore na phanele e sebakeng sa polokelo e batang haholo kapa mokatong o chesang oa fektheri (-20°C ho ea ho +60°C).

Khetho ea Sehlopha sa Leeto

Re etsa li-relay tse tsamaellanang le litlelase tse tloaelehileng tsa maeto:

◆ Sehlopha sa 10: Bakeng sa lienjenere tse nang le mocheso o tlase (ka mohlala, lipompo tse ka tlas'a metsi).

◆ Sehlopha sa 10A/20: E tlwaelehileng bakeng sa dienjene tsa indasteri tse akaretsang.

◆ Class 30: Bakeng sa ho jara lintho tse ngata (ka mohlala, li-fan tse kholo, centrifuges) tse nkang nako e telele ho qala.

◆ Likopo tsa mantlha le Maemo a Tšebeliso

◆ The Industrial Manufacturing: Ho sireletsa mabanta a conveyor, matsoho a liroboto, le li-spindle tsa mochini oa CNC hore li se ke tsa koaleha kapa ho tlala.

◆ HVAC Systems: Ho sireletsa lifani tse kholo tsa centrifugal le li-compressor motors mehahong ea khoebo.

◆ Tlhokomelo ea Metsi: E bohlokoa bakeng sa ho sireletsa lipompo tse ka tlas'a metsi le liaerase hore li se ke tsa omella kapa tsa koala.

◆ Mechine ea OEM: E kopantsoe ka har'a liphanele tsa taolo bakeng sa mechini e pakang, lisebelisoa tsa masela le lisebelisoa tsa ho lokisa lijo.

Precision Manufacturing

Ts'ebetso ea rona ea tlhahiso ke sehlopha sa boenjiniere ba mocheso le ho nepahala ha mochini.

1. Lisebelisoa tsa mantlha:

◆ Bimetallic Strips: Pelo ea sesebelisoa. Re sebelisa li-alloys tsa boemo bo holimo (mohlala, Nickel-Iron/Manganese-Copper) tse nang le li-coefficients tsa katoloso tse baliloeng hantle ho netefatsa ho kobeha ho sa fetoheng ho mocheso o itseng.

◆ Heater Elements: Precision-wound resistance terata (Nichrome) kapa libara tsa koporo tse boima tse hlahisang mocheso o lekanang le sekwere sa hajoale ( I2RI2R ).

◆ Makhokahano: Silver-Nickel (AgNi) kapa Silver-Cadmium-Oxide (AgCdO) bakeng sa li-axiliary contacts (NC/NO), e netefatsa hore ho na le melaetsa e tšepahalang ho PLC kapa khokahanyo.

◆ Bolulo: Polyamide (PA66) ea matla a holimo, e thibelang malakabe kapa Bakelite, e etselitsoeng ho mamella khatello e phahameng ea mocheso.

2. Tlhahiso le Ts'ebetso ea Ts'ebetso:

◆ Component Fabrication: Ho hatisa ka nepo li-strip tsa bimetallic le li-coil tsa heater.

◆ Tekanyetso: Mohato oa bohlokoa ka ho fetisisa. Relay e fetisoa ka kotopo e phahameng ea hona joale ea calibration. Litsebi li lokisa "current setting dial" ho hatella pele bimetallic strip, ho netefatsa hore e tsamaea ka lebelo le nepahetseng (mohlala, 10A, 16A).

◆ Assembly: The bimetallic strip, heater, and trip mechanism (ho kenyeletsoa lever e khethollang bakeng sa ts'ireletso ea ho lahleheloa ke karolo) li kopantsoe ka ho mamellana ha microscopic.

◆ Potting (Boikhethelo): Bakeng sa tikoloho e thata, mochini o kentsoeng ka har'a epoxy resin ho thibela ho bola le ho senyeha ha thothomelo.

◆ Taolo e Matla ea Boleng le Maemo a Teko

Re latela IEC/EN 60947-4-1 le GB/T 14048.4 litekanyetso. Li-protocol tsa rona tsa netefatso ea boleng li etselitsoe ho netefatsa hore relay e etsisa lebelo la mocheso oa enjene hantle.

Lintho tse Tloaelehileng tsa Teko le Mekhoa ea Tlhahlobo ea Feme:

Bokhoni ba rona ba Tlhahiso

Setsi sa rona se na le lisebelisoa tsa ho sebetsana le fisiks e thata ea taolo ea mocheso.

◆ Production Line: Re sebelisa semi-automated assembly lines ka ho khetheha bakeng sa ho sebetsana ka hloko ha li-bimetallic strips, ho thibela khatello ea kelello e ka fetolang boemo ba tsona ba mocheso.

Thepa e tsoetseng pele:

◆ Mabeche a Kelo-pele a Hona Joale: E khona ho enta ho fihla ho 1000A ho etsisa lintho tse ngata tse boima le ho netefatsa linako tsa maeto ka ho nepahala ha millisecond.

◆ Environmental Climate Chambers: E sebelisoa ho lekola mokhoa oa matšeliso a mocheso ho pholletsa le mefuta eohle ea mocheso oa indasteri.

◆ Laser Welding Stations: Bakeng sa ho theha likhokahano tse matla, tse sa sebetsaneng hantle pakeng tsa lisebelisoa tsa hitara le litheminale.

Sehlopha sa Litsebi:

◆ Thermal Engineers: Litsebi tsa ho fetisa mocheso le mahlale a matle a qapang bimetallic geometry.

◆ Calibration Technician: Basebeletsi ba nang le litsebo tse phahameng ba lokisang mekhoa ea maeto ho etsa bonnete ba hore phepelo e 'ngoe le e 'ngoe e kopana le maemo a thata a Sehlopha sa 10A/20/30.

◆ Tiisetso ya Boleng: E ikemiseditse ho sekaseka "trip curve" ho thibela mathata a hlahang lebaleng.

Khetha li-Relay tsa rona tsa Thermal Overload. Ha re etse likaroloana feela; re etsa boenjiniere bo ts'epahalang bo bolokang li-motor tsa hau li sebetsa le mehala ea hau ea tlhahiso e ntse e tsamaea.
