Chigawo chapakati cha chowotcha kutentha, chitetezo cha thyristor

Thyristor ya ng’anjo yosungunuka yosungunula ndiye maziko amagetsi apakati pafupipafupi, ndipo kugwiritsa ntchito kwake molondola ndikofunikira pakugwira ntchito kwa malowa. Ndi zachilendo kuti ng’anjo yosungunula induction iwononge ma thyristors angapo pachaka. Ngati thyristor imawotchedwa nthawi zambiri, ng’anjo yamagetsi idzasiya kupanga, zomwe zidzakhudza kupanga, ndipo zidzachititsa kukhala maso. Mphamvu yogwira ntchito ya thyristor imachokera ku mazana angapo amperes mpaka zikwi zingapo za amperes, ndipo voteji nthawi zambiri imakhala imodzi kapena ziwiri volts. Chitetezo chabwino cha bolodi lalikulu lowongolera komanso kuzizirira bwino kwa madzi ndikofunikira.

Makhalidwe ochulukira a thyristor: Kuwonongeka kwa thyristor kumatchedwa kuwonongeka. Pansi pazikhalidwe zoziziritsa bwino zamadzi, kuchuluka kwachulukira komweku kumatha kufika kupitilira 110%; palibe mphamvu yodzaza ndi voteji, ndiye kuti, silicon imawonongeka mopitilira muyeso. Poganizira kuchuluka kwamagetsi, opanga nthawi zambiri amasankha zida za silicon kutengera 3-4 nthawi yamagetsi opangira popanga.

Zolondola unsembe kuthamanga kwa SCR: 150-200KG/cm2. Malowa akachoka pafakitale, nthawi zambiri amakhala ndi makina osindikizira a hydraulic. Mphamvu zazikulu za wrench wamba sizingafikire mtengo uwu, kotero palibe chifukwa chodera nkhawa kuti silicon ikuphwanyidwa pamene kupanikizika kumayikidwa pamanja; ngati kupanikizika kuli kotayirira, kumawotcha silicon chifukwa cha kutentha kosakwanira.

Kapangidwe ka radiator ka SCR: pabowo loziziritsidwa ndi madzi + thandizo lazambiri zamkuwa. Ngati madzi ozungulira ali olimba kwambiri, amakwera m’madzi ndipo amachititsa kuti kutentha kuwonongeke; ngati masamba ndi zinyalala zina zilowa m’bowo la madzi, zipangitsanso kuti madzi asayende bwino.
