Izinyathelo zokuphepha zokukhethwa nokufakwa kwe-thyristor yesithando somlilo sokuncibilika

Ukunikezwa kwamandla okuvama okuphakathi kuyingxenye ebalulekile yesithando somlilo sokuncibilika, futhi i-thyristor iyinhliziyo yokunikezwa kwamandla okuvama okuphakathi. Ukusetshenziswa kwayo ngendlela efanele kubalulekile ekusebenzeni kwemishini. Ukusebenza kwamanje kwe-thyristor yizinkulungwane ezimbalwa zama-amps, futhi i-voltage ngokuvamile ingaphezu kwenkulungwane ye-volts. Ukuvikelwa okuhle kwebhodi lokulawula eliyinhloko le-intermediate frequency power supply kanye nezimo ezinhle zokupholisa amanzi kuyadingeka. Ngakho-ke, nansi izinyathelo zokuphepha zokukhethwa nokufakwa kwe-SCR yesithando somlilo sokuncibilika.

Izici zokulayisha ngokweqile ze-thyristor: Ukulimala kwe-thyristor kubizwa ngokuthi i-breakdown. Ngaphansi kwezimo ezijwayelekile zokupholisa amanzi, umthamo wamanje wokulayisha ngokweqile ungafinyelela ngaphezu kwe-110%, futhi i-SCR yonakaliswa nakanjani ngaphansi kokucindezela ngokweqile. Ngokucabangela i-voltage yokuhlinzwa, abakhiqizi bavame ukukhetha izingxenye ze-SCR ngokusekelwe izikhathi ezi-4 ze-voltage yokusebenza lapho imishini yokukhiqiza. Isibonelo, lapho i-voltage elinganiselwe yokusebenza yekhabhinethi yokuphakelwa kwamandla emvamisa emaphakathi ingu-1750V, izingxenye ezimbili ze-silicon ezine-voltage ye-standard engu-2500V zikhethwa ukuthi zisebenze ngochungechunge, okulingana ne-standard voltage engu-5000V.

Ukucindezela okulungile kokufakwa kwe-SCR: 150-200KG/cm2. Lapho okokusebenza kuphuma efekthri, kuvame ukucindezelwa ngomshini wokunyathelisa we-hydraulic. Ukusetshenziswa ngesandla kwama-wrenches ajwayelekile akukwazi ukufinyelela leli nani ngamandla amakhulu, ngakho-ke asikho isidingo sokukhathazeka ngokuthi i-thyristor ichotshozwa lapho ilayisha ukucindezela ngesandla; uma ingcindezi ikhululekile, izoshisa nge-thyristor ngenxa yokushisa okungahambi kahle.
