(1) Mhosva 1: Bata kutsauka
Phenomenon 1: Nzvimbo yakabatwa nemunwe haienderane nemuseve wembeva.
Chikonzero 1: Mushure mekuisa mutyairi, pakugadzirisa nzvimbo, pakati pebullseye haina kubatwa vertically.
Solution 1: Recalibrate chinzvimbo.
Phenomenon 2: Kubata mune dzimwe nzvimbo kwakaringana, uye kubata kune dzimwe nzvimbo kwakarerekera.
Chikonzero chechipiri: Huwandu hweguruva kana chikero chinoungana pane inonzwika wave kuratidza mitsetse yakatenderedza pamusoro acoustic wave touch screen, iyo inokanganisa kutapurirana kwemasaisai masaini.
Solution 2: Chenesa touch screen. Teerera zvakanyanya pakuchenesa mitsara yekuratidzira mafungu pamativi mana eiyo touch screen. Paunenge uchichenesa, bvisa magetsi ekubata screen control kadhi.
(2) Mhosva 2: Iyo yekubata sikirini haipindure kubata
Phenomenon: Kana uchibata chidzitiro, museve wembeva haufambi uye hauchinji chinzvimbo chayo.
Chikonzero: Zvikonzero zvechiitiko ichi ndezvizvi:
① Iyo huruva kana chikero chakaunganidzwa pane inonzwika wave kuratidza mitsetse yakatenderedza pamusoro acoustic wave touch screen yakakomba, zvichiita kuti touch screen itadze kushanda;
② Iyo yekubata skrini inotadza;
③ Iyo yekubata skrini yekudzora kadhi inotadza;

Mhinduro kuzvikanganiso zvakajairika muSiemens touch screens
Mhinduro kuzvikanganiso zvakajairika muSiemens touch screens
1. Ruzivo rwekukanganisa kwechikamu chimwe-chikamu kana multi-chikamu chikanganiso chinoratidzwa se "inveter u" kana "inveter v kana w". Chikonzero ndechekuti imwe-phase kana multi-phase inverter inotadza. Kana iyo yepamusoro ikozvino ye switch chubhu i> 3inrms, inrms igbt. Mamiriro ezvinhu aya achaitika kana pane dambudziko neyakarongerwa ikozvino ye inverter, kana pane chimwe chinhu chisina kunaka neanobatsira magetsi echikamu chimwe chegedhi reinverter. Mushure merudzi urwu rwekukanganisa kwaitika, rinogona kukonzera dunhu pfupi pakupera kweiyo frequency converter, kana inogona kukonzera kuti mota izununguke zvakanyanya nekuda kweiyo isiriyo controller marongero. Pane kazhinji mamiriro maviri panguva yekugadzirisa:
(1) Trigger board failure Kana iyo Siemens inverter ichiita pulse width modulation, basa rekutenderera kwepulse series rinorongwa maererano nemutemo we sinusoidal. Iyo modulation wave is sine wave, uye inotakura wave i bipolar isosceles triangle wave. Iyo inopindirana poindi yemodulation wave uye inotakura wave inosarudza iyo pulse series ye inverter bridge inobuda phase voltage. Iyo gonhi rekudzora pani rinoitwa kuburikidza nehombe-yakasanganiswa IC (ASIC), iyo inosanganisira yedhijitari frequency jenareta ine resolution inosvika 0.001hz uye yakanyanya frequency ye500hz uye pulse wide modulator inogadzira matatu-chikamu sine wave. system. Iyi modulator inoshanda asynchronously pane inogara pulse frequency ye8khz. Iyo voltage pulses iyo inogadzira alternately yekubatidza uye kudzima maviri ekuchinja magetsi emagetsi pane imwechete bhiriji ruoko. Kana iri redunhu bhodhi rikatadza, harizokwanisi kuburitsa voltage pulses kazhinji, uye bhodhi inoda kutsiviwa uye kugadziriswa.
2 Inverter mudziyo kukundikana Iyo inverter mudziyo unoshandiswa muSiemens inverters is insulated gedhi bipolar transistor - igbt. Hunhu hwayo hwekutonga hwakanyanya kupinza impedance uye diki diki gedhi ikozvino, saka simba rekutyaira idiki uye rinogona kushanda chete mukuchinja mamiriro. Haikwanise kushanda mune yakakurisa. Iyo inochinja frequency inogona kusvika yakakwira zvakanyanya, asi yayo antistatic performance haina kunaka. Kunyangwe iyo igbt chikamu chakashata inogona kuyerwa neohmmeter. Matanho chaiwo ndeaya anotevera:
● Bvisa simba rekushandura frequency converter;
● Bvisa motokari inodzorwa;
● Shandisa ohmmeter kuyera impedance yeinobuda terminal uye DC yekubatanidza terminals a uye d (ona yakabatanidzwa mufananidzo). Eresa bvunzo imwe neimwe kaviri nekushandura polarity yeohmmeter. Kana iyo igbt yemushanduri wefrequency isingasviki, inofanira kuva: kubva kuU2 kusvika kune yakaderera kushorwa, kana zvisina kudaro, yakanyanya kupikisa; kubva kuU2 kusvika kuD, inopesana nepamusoro; kana zvisina kudaro, iko kushomeka kwakaderera. Zvimwe chetezvo zvinoenda kune zvimwe zvikamu. Kana iyo igbt ikabviswa, ine yakakwirira yekupikisa kukosha nguva mbiri, uye kana ipfupi-inotenderera, ine yakaderera kushomeka kukosha.

3 Kutadza kwesimba rekushandisa resistor Meseji yekukanganisa inoratidzwa se "pulsed resistor", zvinoreva kuti simba rekushandisa resinjini rakawandisa. Pane zvikonzero zvitatu zveizvi: iyo regenerative braking voltage yakawandisa, simba rebhureki rakawandisa kana nguva yekubhureki ipfupi. Iyo simba rekushandisa resistor chimwe chikamu chekuwedzera. Sezvo kuremerwa kwemachira uye kemikari fiber midziyo yakakura inertia mutoro, yakakura-simba switch chubhu uye simba rekushandisa resistor zvakabatana zvakafanana neDC chikamu cheiyo frequency converter kune iyo DA wiring. Basa rayo guru nderekubatanidza magetsi Dynamically kudzikisira overvoltage pane da line paunenge uchibatidza, kudzima kana kurodha. Asi kana mabhureki adarika chiyero, oparesheni inozokanganiswa. Pane kazhinji mamiriro maviri:
(1) Simba rekushandisa resistor kutadza. Mune chaiyo frequency converter, iyo pulse resistor ndeye 7.5ω/30kw. Mushure mekushandisa inverter kwemakore akati wandei, nekuda kwekutanga kwekutanga uye kumira kweiyo inverter, iyo resistor inopisa uye kushomeka kwayo kwakadzikira. Nekudaro, Nokia inverters ine zvakaomesesa zvinodiwa pane yayo yekudzivirira kukosha, iyo inodiwa kuve yakakura kupfuura kana kuenzana ne7.5ω. Naizvozvo, kunyangwe kushorwa kwesimba rekushandisa resitor yeiyi inverter inenge 7.1ω, mhosva iri pamusoro ichaitika uye haizokwanisi kutanga zvakajairika. Gare gare, ndakashandura kune-high-power resistor ine kukosha kwekudzivisa kwe8ω ndisati ndagona kuibatidza.
(2) igbt kukundikana. Pane kukanganisa mune igbt chikamu cheiyo inverter, iyo inokonzera yakawandisa regenerative mhinduro ikozvino uye zvakare inokonzeresa kutadza kwekuremerwa kwesimba rekushandisa resistor.
4. Overheating kukanganisa Mharidzo yemhosva inoratidzwa se "pamusoro pekushisa" nokuti kupisa kwekushisa kwekupisa kwe inverter kwakanyanyisa. Kupisa kweiyo frequency converter kunonyanya kukonzerwa neiyo inverter mudziyo. Iyo inverter mudziyo zvakare ndiyo inonyanya kukosha uye isina kusimba chikamu cheiyo frequency inoshandura, saka tembiricha sensor (ntc) inoshandiswa kuyera tembiricha inoiswawo pamusoro peiyo inverter mudziyo. Kana tembiricha yadarika 60 ℃, iyo frequency converter ichafanobata-alarm kuburikidza nerelay relay; kana yasvika 70 ℃, frequency converter inomira yega kuti izvidzivirire. Kupisa zvakanyanya kunowanzo kukonzerwa nemamiriro mashanu:
(1) Tembiricha ye ambient yakakwira. Mamwe maworkshop ane tembiricha yakakwira uye ari kure zvakanyanya nekamuri yekudzora. Kuti uchengetedze tambo uye kufambisa pa-saiti kushanda, iyo inverter inofanirwa kuiswa panzvimbo mumusangano. Panguva ino, unogona kuwedzera inotonhora yemhepo duct kumhepo inlet ye frequency converter kubatsira kubvisa kupisa.
(2) Fani kukundikana. Iyo yekupedza simba fan ye frequency converter ndeye 24v DC mota. Kana iyo fan inotakura ikakuvadzwa kana coil ikapiswa kunze uye fan ikasatenderera, zvinokonzeresa kuti frequency converter iwedzere.
(3) Singi yekupisa yakasviba zvakanyanya. Kune aluminium fin kupisa kupisa mudziyo kuseri kweiyo inverter ye frequency converter. Mushure mekumhanya kwenguva yakareba, kunze kuchafukidzwa neguruva nekuda kwemagetsi akasimba, zvichikanganisa zvakanyanya mhedzisiro yeradiator. Nokudaro, zvakakosha kuchenesa uye kuchenesa nguva dzose.
(4) Mutoro wakawandisa. Mutoro unotakurwa ne frequency converter unoremerwa kwenguva yakareba, zvichikonzera kupisa. Panguva ino, tarisa magetsi
