Kutentha kotentha kuwerengera mphamvu

1. Mawerengedwe a parameter a thyristor

Mphamvu ya ng’anjo yachitsulo yachitsulo ndi 1500KW, ndipo magetsi obwera ndi 500V. Pambuyo powerengera, deta yotsatirayi ingapezeke.

DC voteji Ud=1.35×500=675V

DC panopa Id=1500000÷675=2200A

Mphamvu yapakati pafupipafupi US=1.5×Ud =1000V

Zoyezera silicon rectifier panopa IF=0.38×Id÷2÷0.85=491A

(Kugawika kwa 2 munjira yomwe ili pamwambapa ndi chifukwa pali magawo awiri a magawo ofanana okonzanso)

Adavotera silicon rectifier voteji UV=1.414×UL=1.414×500=707V

Silicon yosinthira idavotera IF=Id/2=1100A

Inverter silicon oveteredwa voteji UV=1.414×US=1414V

2. Chiwembu chosankhidwa cha chitsanzo cha SCR

Rectifier SCR imasankha KP1500A/2000V, ndiye kuti, yomwe idavotera pano ndi 1500A, ndipo mphamvu yake ndi 2000V. Poyerekeza ndi mtengo wamalingaliro, malire amagetsi ndi nthawi 2.26, ndipo malire apano ndi nthawi 2.43.

The inverter thyristor KK2500A/2000V wapakatikati pafupipafupi mphamvu kotunga, ndiye oveteredwa panopa ndi 2500A, ndi oveteredwa voteji ndi 2000V. Kuphatikiza apo, silicon inverter imalumikizidwa ndi mlatho wa inverter mu kulumikizana kwapawiri-silicon, kotero kuti voteji yeniyeni ya thyristor pa mkono uliwonse wa mlatho wa inverter ndi 5000V. Poyerekeza ndi mtengo wamalingaliro, malire amagetsi ndi nthawi 2.26, ndipo malire apano ndi 2.15 nthawi.

3. NGATI resonant capacitor cabinet

The wapakatikati pafupipafupi resonant capacitors ya yakonzedwa capacitor makabati onse electrothermal capacitors opangidwa ndi Xin’anjiang Mphamvu Capacitor Factory, chitsanzo ndi RFM2 1.0 -2000-1.0S. mphamvu yake ndi 2000KVar, ndi pafupipafupi ntchito ndi 1000Hz.

4. Mphamvu ya ng’anjo yosungunula induction imawerengedwa ngati pw = DC voltage×DC yapano
