Izisombululo kwiimpazamo eziqhelekileyo kwi-Siemens touch screens
Izisombululo kwiimpazamo eziqhelekileyo kwi-Siemens touch screens
1. Ulwazi olunempazamo lwenqanaba elinye okanye lwenqanaba lemininzi luboniswa njenge “inveter u” okanye “inveter v okanye w”. Isizathu kukuba i-single-phase okanye i-multi-phase inverter iyasilela. Ukuba i-peak current ye-tube yokutshintsha i-i> 3inrms, i-inrms i-igbt. Le meko iya kwenzeka ukuba kukho ingxaki kunye nomlinganiselo olinganisiweyo we-inverter, okanye kukho into engalunganga kunye nokunikezelwa kwamandla ancedisayo kwisigaba esinye sesango le-inverter. Emva kokuba olu hlobo lwempazamo lwenzekile, lunokubangela isekethe emfutshane ekupheleni kwesiphumo soguqulo lwamaza, okanye inokubangela ukuba imotor ingcangcazele kakhulu ngenxa yokungachanekanga kolawulo. Kukho iimeko ezimbini ngokubanzi ngexesha lokugcinwa:
(1) Ukungaphumeleli kwebhodi ye-Trigger Xa i-Siemens inverter yenza ukumodareyitha kobubanzi be-pulse, umjikelo womsebenzi wechungechunge lwe-pulse ulungelelaniswa ngokomthetho we-sinusoidal. I-modulation wave yi-sine wave, kwaye i-carrier wave yi-bipolar isosceles triangle wave. Indawo yokudibanisa i-modulation wave kunye ne-carrier wave imisela uchungechunge lwe-pulse ye-voltage yesigaba se-inverter bridge. Iphaneli yokulawula umnyango iphunyezwa nge-IC (ASIC) enkulu ehlanganisiweyo, ebandakanya ijenereyitha yedijithali enesisombululo ukuya kuthi ga kwi-0.001hz kunye nobuninzi be-500hz kunye nemodyuli yobubanzi be-pulse eyenza i-sine-phase ye-sine wave. inkqubo. Le Imodyuli isebenza nge-asynchronously kwi-pulse frequency rhoqo ye-8khz. I-voltage pulses ivelisa ngokutshintshanayo ivule kwaye icime izixhobo zamandla ezibini zokutshintsha kwingalo yebhulorho enye. Ukuba le bhodi yesiphaluka iyasilela, ayiyi kukwazi ukuvelisa i-voltage pulses ngokuqhelekileyo, kwaye ibhodi kufuneka itshintshwe kwaye ilungiswe.
2 Ukungaphumeleli kwesixhobo se-inverter Isixhobo sokuguqula i-inverter esisetyenziswe kwi-Siemens inverters yisango elifakwe kwi-bipolar transistor - igbt. Iimpawu zayo zokulawula ziyi-impedance ephezulu kunye nesango elincinci kakhulu langoku, ngoko ke amandla okuqhuba ancinci kwaye anokusebenza kuphela kwimeko yokutshintsha. Ayikwazi ukusebenza kwimo eyandisiweyo. Ukutshintsha kwayo rhoqo kunokufikelela phezulu kakhulu, kodwa ukusebenza kwayo kwe-antistatic kubi. Ingaba icandelo le-igbt lingalunganga linokulinganiswa nge-ohmmeter. Amanyathelo athile ngala alandelayo:
● Nciphisa unikezelo lwamandla lwesiguquli samaza;
● Nciphisa injini elawulwayo;
●Sebenzisa i-ohmmeter ukulinganisa i-impedance ye-terminal ephumayo kunye neetheminali zoqhagamshelwano ze-DC a no-d (jonga umfanekiso oqhotyoshelweyo). Ukulinganisa uvavanyo ngalunye kabini ngokutshintsha i-polarity ye-ohmmeter. Ukuba i-igbt ye-converter ye-frequency converter ilungile, kufuneka ibe: ukusuka ku-u2 ukuya kwi-resistance ephantsi, ngaphandle koko, ukuchasana okuphezulu; ukusuka ku-u2 ukuya ku-d, kukuxhathisa okuphezulu; ngenye indlela, kukuxhathisa okuphantsi. Kuyafana nakwezinye izigaba. Xa i-igbt inqanyuliwe, inexabiso eliphezulu lokumelana namaxesha omabini, kwaye ukuba i-short-circuited, inexabiso eliphantsi lokumelana.
3 Ukusilela kokusetyenziswa kwamandla ombane Umyalezo wempazamo uboniswa njenge “pulsed resistor”, okuthetha ukuba isixhasi sokusetyenziswa kwamandla sigcwele kakhulu. Kukho izizathu ezithathu zoku: i-voltage yokuvuselela i-braking iphezulu kakhulu, amandla okunyathela aphakamileyo kakhulu okanye ixesha lokunyathela lifutshane kakhulu. I-resistor yokusetyenziswa kwamandla yinxalenye eyongezelelweyo. Ekubeni umthwalo wempahla ye-textile kunye neekhemikhali zefiber ngumthwalo omkhulu we-inertia, i-tube yokutshintsha amandla aphezulu kunye ne-resistor yokusetyenziswa kwamandla idityaniswe ngokuhambelana nenxalenye ye-DC ye-frequency converter kwi-wiring ye-DA. Owona msebenzi wayo uphambili kukudibanisa unikezelo lwamandla Ngokunqabisa umbane ogqithisayo kumgca we-da xa uvula, ucima okanye ulayisha. Kodwa xa i-braking current idlula umlinganiselo, umsebenzi uya kuphazamiseka. Kukho iimeko ezimbini ngokubanzi:
(1) Ukungaphumeleli kokumelana nokusetyenziswa kwamandla. Kwi-converter ye-frequency yangempela, i-pulse resistor yi-7.5ω/30kw. Emva kokusebenzisa i-inverter iminyaka emininzi, ngenxa yokuqalisa rhoqo kunye nokuyeka kwe-inverter, i-resistor ishushu kwaye ukuchasana kwayo kuyancipha. Nangona kunjalo, i-Siemens inverters ineemfuno ezingqongqo kwixabiso layo lokumelana, elifunekayo ukuba libe likhulu okanye lilingane ne-7.5ω. Ngoko ke, nangona ukuchasana kwe-resistor yokusetyenziswa kwamandla kule inverter malunga ne-7.1ω, impazamo engentla iya kwenzeka kwaye ayiyi kukwazi ukuqala ngokuqhelekileyo. Kamva, ndatshintshela kwi-resistor ephezulu enexabiso lokumelana malunga ne-8ω ngaphambi kokuba ndiyivule.
(2) ukungaphumeleli kwe-igbt. Kukho impazamo kwi-igbt inxalenye ye-inverter, ebangela ukugqithiswa kweengxelo ezihlaziyiweyo zangoku kwaye kubangele ukungaphumeleli kokugqithiswa kwe-resistor yokusetyenziswa kwamandla.
4. Ukushisa okugqithisileyo Umyalezo wempazamo uboniswa "njengeqondo lokushisa elingaphezulu" kuba ubushushu bokutshatyalaliswa kobushushu be-inverter buphezulu kakhulu. Ukufudumeza kwesiguquli samaza kubangelwa ikakhulu sisixhobo soguqulo. Isixhobo se-inverter sikwalelona candelo libalulekileyo kunye nelona libuthathaka le-converter frequency, ngoko ke i-sensor yeqondo lobushushu (ntc) esetyenziselwa ukulinganisa ubushushu nayo ifakwe kwindawo ephezulu yesixhobo soguqulo. Xa iqondo lobushushu lingaphezulu kwe-60℃, isiguquli sefrikhwensi siya kuqala i-alarm ngokusebenzisa i-signal relay; xa ifika kwi-70 ℃, i-frequency converter iya kuyeka ngokuzenzekelayo ukuzikhusela. Ubushushu obugqithisileyo ngokuqhelekileyo bubangelwa ziimeko ezintlanu:
(1) Iqondo lobushushu kwindawo ethile liphezulu. Ezinye iindibano zocweyo zinamaqondo obushushu aphezulu kwaye zikude kakhulu negumbi lolawulo. Ukuze ulondoloze iintambo kunye nokuququzelela ukusebenza kwendawo, i-inverter kufuneka ifakwe kwisayithi kwindawo yokusebenzela. Ngeli xesha, unokongeza umbhobho womoya obandayo kwi-air inlet yeconverter frequency ukunceda ukukhupha ubushushu.
(2) Ukusilela kwabalandeli. I-fan yokukhupha ye-converter frequency yi-24v DC motor. Ukuba i-fan bear yonakalisiwe okanye i-coil itshisiwe kwaye i-fan ayijikelezi, iya kubangela ukuba isiguquli sefrikhwensi sitshise kakhulu.
(3) Isitya sokufudumala simdaka kakhulu. Kukho isixhobo se-aluminiyam yokuphelisa ubushushu emva kwe-inverter ye-frequency converter. Emva kokusebenza ixesha elide, ngaphandle kuya kugutyungelwa ngothuli ngenxa yombane ongatshintshiyo, ochaphazela kakhulu umphumo we-radiator. Ngoko ke, kuyimfuneko ukucoca kunye nokucoca rhoqo.
(4) Umthwalo omninzi. Umthwalo othwalwa yi-converter frequency igcwele kakhulu ixesha elide, ibangela ubushushu. Ngeli xesha, khangela umbane
