Umzi-mveliso oFakwayo wokuLayishwa kweThermal oLungisiweyo

CDADA, umenzi kunye nomthengisi osekelwe e-China, unikeza uluhlu olubanzi lwezixhobo zombane eziphantsi kwe-voltage, kubandakanywa ukuhanjiswa kwe-thermal overload. Iqela lethu lobuchwephesha libonelela ngeenkonzo ezibanzi ze-OEM yokwenza ngokwezifiso kunye nenkxaso yobugcisa emva kokuthengisa. Siyayamkela imibuzo yakho.

Yintoni i-Thermal Overload Relay?

I-Thermal Overload Relay sisixhobo esikhuselayo esenzelwe ukucima imoto yombane xa izoba umsinga omninzi ixesha elide, nto leyo ebangela ukuba ubushushu bugqithise. Ngokungafaniyo ne-fuse okanye umgangathoumephuli wojikelezoesabela kumbane ophezulu ngoko nangoko (iisekethe ezimfutshane), iTOR isebenzisa uphawu lwexesha eliguquguqukayo. Oku kuthetha ukuba ixesha lokuhamba liyancipha njengoko ukonyuka kwangoku kunyuka, kubonisa ngokugqibeleleyo umthamo we-thermal we-motor windings.

Undoqo wobugcisa bethu uxhomekeke kumgaqo we-bimetallic strip: iintsimbi ezimbini ezinee-coefficients ezahlukeneyo zokwandiswa kwe-thermal ezidityanisiweyo. Xa ishushu yi-motor current, i-strip iyagoba. Ukuba i-current idlula ummiselo okhuselekileyo wexesha elithile, i-strip igoba ngokwaneleyo ukukhubaza ngoomatshini abafowunelwa abancedisayo, ukusika amandla kwikhoyili ye-motor starter.

Iintlobo kunye noHlelo

Ubuchule bethu bokuvelisa bubandakanya itekhnoloji epheleleyo yokhuselo lomthwalo ogqithisiweyo, olungiselelwe iimfuno ezahlukeneyo zemizi-mveliso.

Uhlobo	Ezona mpawu	Usetyenziso oluqhelekileyo
I-Bimetallic Relay	Ukufudumeza ngokuthe ngqo okanye ngokungathanga ngqo ngeekhoyili zesifudumezi. Inamandla, ilula, kwaye ineendleko ezifanelekileyo.	Injongo ngokubanzi yokhuseleko lweemoto (iipompo, iifeni, abahambisi).
I-Electronic Relay	Imeko eqinileyo, akukho malungu ashukumayo. Ibonisa ukuva okuchanekileyo kwangoku, ukufumanisa ilahleko yesigaba, kunye nokukhusela umhlaba.	Iinkqubo ezibalulekileyo, imithwalo ephezulu ye-inertia, kunye neendawo ezinobungozi.

Okuzenzekelayo: Iseta ngokutsha ngokuzenzekelayo emva kokupholisa (iinkqubo ezingaqwalaselwanga).	Imanuwali: Oomatshini apho ukuqalisa kwakhona okungalindelekanga kuyingozi. Okuzenzekelayo: HVAC, iimpompo kwindawo ezikude.

Imisebenzi enguNdoqo kunye noKhuseleko oluBukrelekrele

Ugqithiso lwethu lwe-Thermal Overload ayizokutshintsha nje ezilula; bangabagcini abakrelekrele bemoto.

● Ukhuseleko lokuNxibelela: Umsebenzi wokuqala. Ngokudibanisa langoku ekuhambeni kwexesha ( I2tI2t ), ireyiyi ikhusela ukugqunywa kwemoto ekuwohlokeni kwe-thermal. Ivumela imisinga yokugxalathelana okwexeshana (ukuqala i-motor) ngaphandle kokukhubeka kwenkathazo kodwa isabela ngokungqongqo kwi-overload eqhubekayo.

● Inqanaba loKhuseleko lokusilela (iSigaba esinye): Kwisistim yezigaba ezithathu, ukuba isigaba esinye silahlekile, injini itsala umsinga ogqithisileyo kwizigaba ezibini ezishiyekileyo ukugcina itorque. Iireyiyidi zethu zinesixhobo esahlukileyo (okanye i-electronic sensing) ebona oku kungalingani kwaye ihambe ngoko nangoko, ithintele injini ukuba ingatshi.

● Imbuyekezo yoBuqondo: Inkalo ebalulekileyo yeemeko zoshishino. Iireyiyi zethu zixhotyiswe ngomcu we-bimetallic obuyekezayo omelana neempembelelo zokutshintsha kweqondo lobushushu. Oku kuqinisekisa ukuba indawo yohambo ihlala ichanile nokuba indawo yolawulo ikwindawo yokugcina impahla ekhenkcezayo okanye kumgangatho oshushu womzi-mveliso (-20°C ukuya +60°C).

Uveliso oluchanekileyo

Inkqubo yethu yokuvelisa i-masterclass kubunjineli be-thermal kunye nokuchaneka komatshini.

1. Izinto ezingundoqo:

◆ Iimigca yeBimetallic: Intliziyo yesixhobo. Sisebenzisa i-alloys yodidi oluphezulu (umzekelo, i-Nickel-Iron/Manganese-Copper) kunye ne-coefficients yokwandisa ebalwe ngokuchanekileyo ukuqinisekisa ukugoba okuhambelanayo kumaqondo okushisa athile.

◆ Ielementi zeHeater: Precision-wound resistance wire (Nichrome) okanye iintsimbi zobhedu ezisindayo ezivelisa ubushushu ngokomlinganiselo kwisikwere sangoku ( I2RI2R ).

◆ Abafowunelwa: I-Silver-Nickel (AgNi) okanye i-Silver-Cadmium-Oxide (AgCdO) yabafowunelwa abancedisayo (NC/NO), iqinisekisa umqondiso othembekileyo kwi-PLC okanye kwi-contactor.

◆ Izindlu: Amandla aphezulu, i-flame-retardant Polyamide (PA66) okanye i-Bakelite, eyilelwe ukumelana noxinzelelo oluphezulu lobushushu.

2. IMveliso kunye noKusetyenzwa komsebenzi:

◆ Ukwenziwa kwecandelo: Ukunyathela ngokuchanekileyo kwemigca ye-bimetallic kunye neekhoyili zeheater.

◆ Ulungelelwaniso: Elona nyathelo libalulekileyo. I-relay idlula kwitonela yokulinganisa ephezulu yangoku. Amagcisa ahlengahlengisa "udawulo lwangoku lokumisela" ukucinezela kwangaphambili ngoomatshini umcu we-bimetallic, uqinisekisa ukuba uhamba ngokomlinganiselo ochanekileyo (umzekelo, 10A, 16A).

◆ Assembly: I-bimetallic strip, iheater, kunye ne-trip mechanism (kuquka i-lever eyahlukileyo yokhuseleko lwenqanaba lokulahlekelwa) zidityaniswe ne-microscopic tolerances.

◆ Ukubumba (Ngokhetho): Kwiimeko ezingqongileyo ezirhabaxa, indlela yangaphakathi ifakwe kwi-epoxy resin ukunqanda ukubola kunye nomonakalo wokungcangcazela.

◆ ULawulo loMgangatho olungqongqo kunye neMigangatho yoVavanyo

Sithobela i-IEC/EN 60947-4-1 kunye nemigangatho ye-GB/T 14048.4 . Iiprothokholi zethu zokuqinisekisa umgangatho ziyilelwe ukuqinisekisa ukuba i-relay ilinganisa ijika lemoto ngokugqibeleleyo.

Izinto zoVavanyo oluMgangatho kunye neNqobo yoHlolo lwasefektri:

Into yovavanyo	Isalathiso esisemgangathweni	Umgangatho wethu weFactory & Indlela
Trip Class Verification	Iqinisekisa igophe langoku.	Ivavanywe ku- 7.2 x Ikalwe ngoku. Iklasi ye-10 kufuneka ihambe nge- < 10s; Iklasi ye-20 kwi <20s.
Ulungelelwaniso lweLizwe elibandayo	Iqinisekisa ubunyani ukusuka ekuqaleni.	Inyusiwe yangoku ukuya ku- 1.05 x Ulungiselelo. AKUFUNEKA luhambe ngeyure ezi-2. Emva koko inyuswe ukuya ku- 1.2 x Ukumisela. Kufuneka uhambe kwiiyure ezi-2.
UVavanyo lokuSilela kwiSigaba	Iqinisekisa ukhuseleko lwenqanaba elinye.	Isigaba esinye sangoku sisete ku-0, ezinye zikwinqanaba langoku. I-Relay kufuneka ihambe ngexesha elithile (umzekelo, < 2 mins).
Imbuyekezo yeTemp ye-Ambient	Uqinisekisa uzinzo kubushushu/kubanda.	Ivavanywe kwigumbi lemozulu kwi--20°C kunye +60°C. Ukwahluka kwendawo yohambo kufuneka kube < ±5%.
Ubomi boomatshini	Iqinisekisa ukuqina.	I-1,000 ukuya kwi-10,000 imijikelo yokusetha ngokutsha ngesandla kunye nemisebenzi yohambo ngaphandle kokusilela koomatshini.

Ubuchule bethu boMveliso

Indawo yethu ixhotyiselwe ukujongana nefiziksi ebuthathaka yolawulo lobushushu.

◆ Umgca wokuVelisa: Sisebenzisa iilayini zeautomated assembly ezilungiselelwe ngokukodwa ukuphatha iintambo ze-bimetallic, ukunqanda uxinzelelo olunokutshintsha iimpawu zabo zobushushu.

Izixhobo ezikwinqanaba eliphezulu:

◆ Iibhentshi zokuLungelela zangoku eziPhezulu: Iyakwazi ukutofa ukuya kuthi ga ku-1000A ukulinganisa umthwalo onzima kunye nokuqinisekisa amaxesha ohambo ngokuchaneka kwe-millisecond.
