Phase Control Thyristor (Dawb Floating Hom)

Nqe lus piav qhia:

Nrog rau kev txhim kho lub zog thiab muaj peev xwm ntawm cov khoom siv hloov pauv, tshwj xeeb tshaj yog HVDC kis tau tus mob, qhov tso zis hluav taws xob muaj peev xwm ntawm chav tsev thyristor yog thov kom nce raws li, xws li yuav txo qhov ntau ntawm cov khoom siv ntawm thyristor nyob rau hauv series thiab parallel txuas circuit.Cov cuab yeej loj thiab qhov hnyav yuav raug txo, qis peev, txawm tias tam sim no thiab txawm tias qhov hluav taws xob yuav raug pom tau yooj yim, kev lag luam txhim khu kev qha thiab kev lag luam tus nqi yuav nce ntxiv.

Lub tshuab dawb ntab silicon ua haujlwm los tsim lub zog siab siab tam sim no thyristor yuav ua tau raws li cov txheej txheem siab thov.Thiab nyob rau hauv 2019 Lub Xya hli ntuj, RUNAU Electronics tau tsim 5200V thyristor nrog 5 "chip ua tiav thiab muab rau cov neeg siv khoom siv hauv Tuam Tshoj HVDC project.

Taw qhia:

1. Chip

Cov txheej txheem siab thyristor nti tsim los ntawm RUNAU Electronics yog cov cuab yeej pub dawb siv.Nws yog qhov zoo lees paub tias yog qhov tseeb thiab paub tab thev naus laus zis rau kev tsim lub zog hluav taws xob siab thyristor.Nws tau dav siv los ntawm cov khoom siv hauv ntiaj teb feem ntau.

Cov txheej txheem diffusion tau ua kom zoo dua nyob rau hauv qhov ntom ntom thiab dav kom nce qhov kev tiv thaiv hluav taws xob, txo qis hauv lub xeev qhov hluav taws xob poob, thiab txhim kho qhov cuam tshuam & dynamic yam ntxwv.Cov qauv photolithography tshiab tau tsim los txhim kho lub di/dt thiab dv/dt feature.Cov qauv kev sib cuag ntawm cov nti tau rov ua dua los tiv thaiv ntug ntawm silicon wafer thiab cathode nto, qhov rov qab voltage kev ua tau zoo yuav zoo dua.

2. Encapsulation

Qhov kom zoo dua ntawm cov tshuab silicon dawb ntab yog qhov deformation ntawm silicon thiab molybdenum wafer tswj tau zoo heev thiab molybdenum wafer noj txo.Thaum lub tiaj tus ntawm silicon wafer thiab tooj liab thaiv ntawm pob yog qhov xav tau zoo ib yam li qhov yuav tsum tau muaj kev sib luag thiab kev ntxhib los mos yog siab dua li kev siv tshuab chip alloy.Los ntawm kev txhim kho tas mus li thiab kev tsim kho tshiab, RUNAU Electronic tau kov yeej txhua qhov kev nyuaj thiab teeb meem.Cov tshuab tsis pub ntab, lub zog siab zog siab thyristor nrog kev txhim khu kev qha thiab kev lag luam zoo tau tsim thiab muab rau cov neeg siv khoom.Feem ntau ntawm lawv yog ntsia rau hauv lub siab fais fab tswj rectifier, high voltage soft starter, HVDC fais fab kis, locomotive traction, dynamic reactive zog them thiab mem tes fais fab daim ntawv thov system.

Technical specification

1. Phase tswj thyristor nrog alloy hom nti tsim los ntawm RUNAU Electronics, ntau yam ntawm I_TAVlos ntawm 350A txog 5580A thiab V_DRM/V_RRMLos ntawm 3400V rau 8500V.
2. I_GT, V_GTthiab kuv_Hyog qhov ntsuas qhov ntsuas ntawm 25 ℃, tshwj tsis yog hais tias lwm yam, tag nrho lwm yam tsis yog qhov ntsuas qhov ntsuas raws li T_jm;
3. I²t = kuv²F SM × tw/2, tw = Sinusoidal ib nrab yoj tam sim no puag dav.Ntawm 50Hz, I²t = 0.005 Nws²FSM (A²S);
4. 60Hz: ib_FSM(8.3ms) = kuv_FSM(10ms) × 1.066, T_j=T_j;Kuv²t(8.3ms) = kuv²t(10ms) × 0.943, T_j=T_jm
