Ongororo Yechikonzero chekupiswa kweThyristor

Panguva yekushandiswa kwechoto chepakati-frequency, thyristor inopisa inowanzoitika, iyo inowanzogumbura vashandi vekuchengetedza epakati frequency furenace, uye dzimwe nguva haigone kuzvigadzirisa.Zvinoenderana nemarekodhi ekuchengetedza epakati frequency choto kwemakore mazhinji, iyo data inogona kuoneka pazasi kuti itariswe nevashandi vekugadzirisa.

1.Mvura inotonhorera jekete ye inverter thyristor inogurwa kana kuti kutonhora kunoderedzwa, saka sleeve yemvura inotonhorera inoda kuchinjwa.Dzimwe nguva zvakakwana kuona kuwanda kwemvura uye kumanikidzwa kwejasi rekutonhora kwemvura, asi kazhinji nekuda kwedambudziko rehutano hwemvura, chiyero chechiyero chinosungirirwa kumadziro ejasi rekutonhora kwemvura.Nekuti chiyero imhando yemhando yekupisa conductivity kusiyanisa kunyangwe paine kuyerera kwakakwana kwekuyerera kwemvura, kupisa kwekupisa kunoderedzwa zvakanyanya nekuda kwekuparadzaniswa kwechiyero.Nzira yekutonga ndeyokuti simba riri kushanda nesimba rinoita maminetsi gumi pasi pane iro rehuwandu hwekufashukira.Ipapo simba rakamira nekukurumidza, uye musimboti weiyo silicon inodzorwa element yakabatwa nekukurumidza neruoko mushure mekumira.Kana ikanzwa inopisa, kukanganisa kunokonzerwa nechikonzero ichi.

2.Kubatana pakati pe groove uye conductor kwakashata uye kwakaputsika.Tarisa slot uye batanidza waya, uye ibate maererano nemamiriro chaiwo.Kana waya yekubatanidza chiteshi iine tie mamiriro ekubata kwakashata kana mutsara wakaputsika, simba rinokwira kune imwe kukosha rinoburitsa chiitiko chemoto, icho chinokanganisa basa rakajairwa remidziyo, inotungamira kuchengetedzwa kwemidziyo.Dzimwe nguva overvoltage yenguva pfupi inogadzirwa kumativi ese ari maviri pane thyristor nekuda kwekuneta.Iyo iyo overvoltage yekudzivirira yakanonoka, inozobhuroka iyo thynstor element.Overvoltage uye overcurrent inowanzoitika panguva imwe chete.

3.Instantaneous burr voltage ye thyristor yakanyanya kukwira kana thyristor ikadzoserwa.Mudunhu guru repakati frequency simba rekupa, iyo instantly reverse phase burr voltage inotorwa nekupokana uye kutorwa.Kana iyo resistor uye capacitor yedunhu yakavhurika munharaunda yekunyura ichaita kuti pakarepo reverse burr voltage yakakwira uye kupisa thyristor.Muchiitiko chekukundikana kwesimba, tinoshandisa WAN Xiu tafura kuyera absorpti pakupikisa uye capacitance yeabsorption capacitor, kuitira kuti tione kana pane chikanganiso mukupikisa capacitance absorption circuit.

4.Mutoro unoderedza insulation ye grou nd: kusungirirwa kwechitsiko chemutoro kunoderera, zvichiita kuti mutoro upise moto pakati pevhu, uchivhiringidza nguva inokonzera kuputika kana kuumba mhepo yakakwirira kumativi ose e thyristor uye. kupisa chinhu chinonzi thyristor.

5.Pulse trigger circuit fault: Kana iyo trigger pulse yakangoerekana yarasika kana chigadziro chiri kushanda, chichaita kuti mhepo yakazaruka ye inverter uye ibudise mhepo yakakwirira pamagumo ekubuda kwepakati pemagetsi emagetsi uye kupisa chinhu chinonzi thyristor.Rudzi urwu rwekukanganisa kazhinji kuumbwa kweiyo inverter pulse uye kukanganisa kweinobuda dunhu.Inogona kutariswa neoscilloscope, uye inogonawo kunge iri iyo yakaipa kusangana kweiyo inverter lead wire, uye inogona kuzunungusa waya yakabatana neruoko uye kuwana chikanganiso chinzvimbo.

6.Iyo midziyo inovhura kana mutoro uchishanda: Kana chigadziro chiri kushanda nesimba guru, kana kamwe-kamwe mutoro uri munharaunda yakazaruka, silicon controlled element ichapiswa kunze kwekuguma kwekubuda.

7.Mutoro wacho wakapfupika kana midziyo ichimhanya: Kana iyo midziyo iri kushanda nesimba guru, kana mutoro wacho ukangoerekana wapfupika, uchange uine yakakura pfupi yedunhu ikozvino kukanganisa pa SCR: uye kana pamusoro pezvino kudzivirira chiito. haigone kuchengetedzwa, iyo SCR zvinhu zvichapiswa kunze.

8.Kudzivirirwa kwegadziriro yekukundikana (kukundikana kwekudzivirira): Kuchengetedzwa kweSCR kunonyanya kuenderana nekudzivirira.Kana paine kutadza mukudzivirira) pane sisitimu, michina yacho haina kurongeka zvishoma mubasa rayo, izvo zvinounza dambudziko kune SCR kuchengeteka.Naizvozvo, zvakakosha kuti utarise system yekudzivirira kana SCR ichipisa.

9.SCR kutonhora system kutadza: Thyristor inopisa zvakanyanya pabasa uye inoda kutonhodzwa kuti ive nechokwadi chekushanda kwayo kwakajairika.Kazhinji, kune nzira mbiri dzekutonhodza iyo silicon inodzorwa rectifier: imwe kutonhora kwemvura uye imwe kutonhora kwemhepo.Kutonhodza kwemvura kunoshandiswa zvakanyanya, uye kutonhora kwemhepo kunongoshandiswa kune magetsi asingasviki 100KW.Kazhinji, iyo yepakati frequency michina ine kutonhora kwemvura inoshongedzerwa nemvura inodzivirirwa yedunhu, asi iri kuchengetedzwa kweiyo yakazara kufurira.Kana imwe mvura yakavharwa, haigoni kuchengetedzwa.

10.Reactor iri mudambudziko: Kubatidza kwemukati kwe reactor kunoita kuti cur nt side ye in verier side rikanganiswe.
