Injini yokukhusela EOCR-SS
I-EOCR-SS yindlela yokudlulisa ngokuphindaphindiweyo kunye nomlinganiselo omncinci wexesha lokusebenza. Isalathisi sengqondo esetyenziswayo ngoku kulandelwa ngokusebenzisa umgca wesigaba esisekugqibeleni nge-transformers ezimbini (CT). Xa umthwalo awuqhelekanga, amandla okulawula loop anqunyulwa ngu-relay yangaphakathi ukufezekisa injongo yokukhusela umthwalo. Iinzuzo zobukhulu obuncinci, ubunzima obunzima, ukuphazamiseka, ukungabikho kwengxolo, ukusebenza okuthembekileyo, umsebenzi wokukhusela oqinileyo, ukufakela okufanelekileyo nokusetyenziswa. Kubaluleke kakhulu ukukhuselwa ngokugqithiseleyo kwamajini kunye nezixhobo.
Isingeniso somsebenzi:
1-1. Ngaphezulu kwelo xesha, ukulahlekelwa kwesigaba, ukuvimba kunye neminye imisebenzi yokukhusela.
1-2. Ukukhuselwa kungafumaneka kwi-0.1 ukuya ku-60 A usebenzisa imizekelo emithathu eyahlukeneyo (05, 30, 60). Ukuba lidlula i-60A (ubuninzi be-800A), kufuneka idibaniswe nabaguquleli bangaphandle.
1-3. Qalisa ukulibaziseka, ukulibaziseka kwamanyathelo, kunye nexabiso elingaphezu kwexabiso elingasetyenziselwa ukwahlukana.
1-4. Ukunikezwa kwamandla okusebenza ngu-180 ~ 480VAC (24V, 36V, 110V, 660V ukuveliswa kwamandla omyalelo wokunikezelwa kwamandla).
1-5. Izibane ezibonakalisiweyo ezimbini (i-LED) zibonisa isimo sesimo (eluhlaza) kunye nesimo senxaxheba (obomvu).
1-6. Emva kokuba i-relay isebenze, inokusetyenzwa kwakhona ngokusetyenzwa kwakhona (cindezela inkinobho ye-RESET) kunye nemimoya yokucima.
1-7. Le mveliso inemizekelo emibini eyahlukeneyo yangoku i-0.5-6A 5-70A
2, indlela yokubeka
Emva kokugqiba i-wiring ngokubhekiselele kumzobo wesibambiso, ulayini kufuneka ulungiswe ukuze kuqinisekiswe ukuba ulayini ungasebenzisa ngokuqhelekileyo njengolu hlobo lulandelayo:
2-1. Ngaphambi kokuba i-motor iqale, ngokwexesha langempela lokuqala lomqhubi, hlengisa ukulibaziseka kokuqala (D-TIME) iqhosha kule xabiso (mhlawumbi ungeze imizuzwana emi-2 ukuya kweyesi-3). Ukuba akuqinisekanga, lungisa utshintsho kwixabiso eliphezulu.
2-2. Lungisa i-knob yokubambezeleka kwezenzo (O-TIME) kunye ne-knob ye-overcurrent setting (LOAD) kwixabiso eliphezulu.
2-3. Qala imoto. Emva kokuba imoto iqhume kakuhle (oko kukuthi, ixabiso le-D-TIME lidlula ixesha lokulibaziseka kokuqala), ukujikelezwa kokujikeleza kokuhamba (LOAD) ijikeleza ngokukhawuleza kwinqwelo elide kuze kube yilapho isibonakalo esibomvu (i-LED) siphezu. Oku kusebenza ngokusemthethweni. I-100% yexabiso langoku. Yitshintshela i-knob kwi-clockwise kude kube lula ukukhanya kwesalathisi esibomvu (ngexesha elimisiweyo lokulibaziseka kwe-O-TIME), eyi-103% yexabiso elikhoyo langoku. Qhubeka ujikeleza ngaphezulu kwikhowudi yokucwangcisa yangoku (LOAD) ukujonga iwashi ukuyibeka kwixabiso elifanelekileyo. (Kunconywe ixabiso eliphindaphindiweyo liphakathi kwe-110% kunye ne-125% yexabiso langoku lisebenza ngoku)
2-4. Qalisa kwakhona ixesha lokulibaziseka kokuqala (D-TIME) ngokusebenza ngokuqhelekileyo kokuqala kwemoto. Inani eliqhelekileyo lokusekwa li-2 ukuya kweyesi-3 imizuzwana emikhulu kunexabiso langempela.
2-5. Hlela kwakhona ixesha lokulibaziseka kwexesha (O-TIME) ngokubhekiselele kwimeko ekhoyo.
2-6. Emva kokumisa, cinezela iqhosha lokuhlola (TEST) ukujonga isiphumo sokumisela.
3. Inkcazo yemeko yesalathisi
3-1. Emva kokuba ulayini lubekwe amandla, ukukhanya okuluhlaza (LED) kukhanya, kubonisa ukuba ungene kwiimeko eziqhelekileyo.
3-2. Ukuba ukukhanya komqondiso obomvu kuqhutywe ngexesha losebenziso, kubonisa ukuba umsebenzi wokukhusela lo myalezo usebenza.
Ezine. Imiyalelo yenkinobho yokuhlola
Ukulayishwa kufuneka kuhlolwe rhoqo ngexesha lomsebenzi ngolu hlobo lulandelayo: Ngaphantsi kwemeko yokulayisha, cinezela inkinobho yokuvavanya (TEST) kwaye ungavumeli ukuhamba.
Ukukhanya koluphawu obomvu kuvuliwe. Emva kokulibaziseka kokuqala kunye nexesha lokulibaziseka kwexesha, unokuva isandi sokulayishwa kwe “clatter”. Ngeli xesha, ukukhupha iqhosha lokuvavanya (UVAVANYO), ukukhanya okubomvu okuhlala kubakho, kubonisa ukuba ulayini usebenza ngokuqhelekileyo. Emva kokugqiba umsebenzi okhankanywe ngasentla, cinezela iqhosha le-RESET ukusetha kwakhona kwaye ufake ifayile evumelekileyo yokusebenza.
