iimveliso

Uvavanyo lwe-Pulse lutshintsha umthwalo ukuya kwelinye icala emva koko ubuye kwakhona. Oku kufuneka kwenzeke ngokukhawuleza kangangokuba kungabikho siphumo kumatshini okanye kwiziphumo zoqhagamshelwano zesixhobo somthwalo. Umsebenzi oKhethekileyo woVavanyo lwePulse uxhomekeke ekubeni okanye Akukho ukubhaqwa koMthwalo kwenziweyo. A. Ukuba Akukho ukubhaqwa koMthwalo kuvuliwe, ibhloko ijonga ubukho okanye ukungabikho komthwalo wangoku, usebenzisa isiqhelo Akukho ukuLayisha umda. Oku kuqinisekisa ukuqhubeka komthwalo. B. Ukuba Akukho ukufunyaniswa koMthwalo AKUFANELEKILEYO, uvavanyo lwe-Pulse Testing kuphela ukuba i-block output iguqula i-voltage. Uvavanyo lwe-Pulse luqala ngee-pulses ezimxinwa. Ukuba imeko efanelekileyo echazwe ngasentla ifunyenwe kwi-try yokuqala, uvavanyo lugqityiwe. Ukuba imeko ayifumanekanga, uvavanyo luphinda luphindwe ngokulandelelana kwee-pulses ezinde (2.5mS increments) de kube yimpumelelo. Elona xesha liphezulu loVavanyo lwePulse yi-16 mS. Ukuba eli xesha lifikelelwe kwaye umphumo awukaphumeleli, umyalezo wempazamo uyenziwa. Ububanzi be-pulse obuqhelekileyo obubonwa ngumthwalo bufutshane kune-16mS ephezulu. A. Ngaphandle kokufunyanwa koMthwalo kunikwe amandla, i-pulses requlred ingaba yinde ngenxa yokunyuka kwexesha lomthwalo wangoku kunye ne-inductance yomthwalo. Izixhobo zamandla ezinje ngabafowunelwa kunye nee-actuators ziya kudibana nobukhulu bepulse ububanzi. Izixhobo ezinjalo zitsala imisinga ephakathi kwaye azichatshazelwa yi-pulsing. Ukuhanjiswa kweempawu zamandla asezantsi kunokuba nomzobo ophantsi wangoku, iikhoyili ze-inductance ephezulu, kunye nokusebenza ngokukhawuleza. Ezo zixhobo kusenokufuneka zihlolisiswe ngenyameko. B. Ngaphandle kokufunyanwa koMthwalo AKUNJALO kwenziwe, uVavanyo lwePulse oluyimpumelelo ludla ngokukwenzeka kwi-4mS ukuya kwi-6mS. Ixesha linokuba lide kancinci ukuba kukho imithwalo ye-capacitive. Umthwalo ofanelekileyo woVavanyo lwePulse Umthwalo ochasayo kunye/okanye ongenisayo ufanelekile kuVavanyo lwePulse ukuba nayiphi na kwezi zilandelayo ziyinyani: A. Ukuba Akukho ukubonwa koMthwalo kuvuliwe: 1. Ubuncinci bokuthatha ngoku bomthwalo bungaphantsi kwe-No Load threshold yebhloko. Umlinganiselo ophezulu webhloko yi-50mA, kodwa amaxabiso aqhelekileyo angama-20mA ukuya kwi-35mA. Xa uvavanya i-off-off-on-operation, izixhobo eziqhelekileyo ezinemisinga ye-75mA ukuya phezulu zifanelekile. Xa uvavanya umsebenzi wokucinywa, izixhobo ezithile zinokufuna ukongezwa kwe-flyback diode ngqo kwikhoyili yomthwalo ukwandisa ixesha lokuyeka. 2. Ubuncinci bokulibaziseka bukhulu kune-16mS, kwaye ukulibaziseka kokuyeka kukhulu kune-5mS. Izixhobo ezinomsebenzi ocothayo okanye obambezelekayo zisenokungafanelekanga kuba ziya kukhwela ubuninzi bobubanzi be-pulses. 3. Ixesha lokunyuka kwangoku kumthwalo, kwi-voltage eqhelekileyo, ivumela i-peak current ukuba ifikelele embundwini ngexesha elingaphantsi kokulibaziseka kwesixhobo, kunye nangaphantsi kwe-16mS ubuninzi be-pulse ububanzi. Umthwalo wangoku kufuneka ufikelele kwi-50mA ngaphambi kokuba utshintshe abafowunelwa. Ukuba kuyimfuneko, umthamo wangoku unokunyuswa ngokongeza umthwalo wokuchasa kwi-coil, kunye nokuphela kwesixhobo socingo. Oku kuya kuvumela uvavanyo lokuqhubekeka kocingo, kodwa isenokungayiboni ikhoyili evulekileyo. B. Ukuba akukho mthwalo wokubonakala AWUVUNZISWA, ubuncinci bokuthathwa okanye ukulibaziseka kokuyeka mkhulu kune-5mS.
