Njikwa usoro Thyristor (Ụdị ese n'elu n'efu)

Nkọwa:

Site na mmepe nke ịba ụba ike na ikike nke akụrụngwa ntụgharị, ọkachasị nnyefe HVDC, ikike mmepụta nke unit thyristor na-arịọ ka ịbawanye ya, nke a ga-ebelata ntinye nke thyristor n'usoro na sekit njikọ njikọ.A ga-ebelata nha na ịdị arọ nke ngwaọrụ ahụ, ntinye ego dị ala, ọbụna ugbu a na ọbụna voltaji ga-adị mfe, ọrụ a pụrụ ịdabere na ya na uru azụmahịa ga-abawanye nke ukwuu.

Teknụzụ silicon na-ese n'elu n'efu nke arụ ọrụ iji rụpụta thyristor dị elu dị ugbu a ga-egbo mkpa ngwa dị elu.Na 2019 Julaị, RUNAU Electronics ewepụtala 5200V thyristor nwere mgbawa 5 nke ọma ma wetara ndị ahịa nke etinyere na ọrụ China HVDC.

1. Chip

Chip thyristor dị elu nke RUNAU Electronics rụpụtara bụ teknụzụ na-ese n'elu n'efu.Ọ bụ nke a nabatara nke ọma dị ka teknụzụ kachasị ọhụrụ na tozuru oke maka imepụta thyristor voltaji dị elu.Ndị na-emepụta klaasị ụwa kacha etinye ya n'ọrụ.

Emebere usoro mgbasa ozi kachasị na njupụta na obosara iji welie nkwụsi ike voltaji, belata ọdịda voltaji na steeti, wee melite ihe mkpali & njirimara ike.Emebere ụkpụrụ fotolithography ọhụrụ iji kwalite njirimara di/dt na dv/dt.Emegharịrị nhazi kọntaktị nke mgbawa iji chebe nsọtụ nke silicon wafer na elu cathode, a ga-emeziwanye arụmọrụ voltaji nke ukwuu.

2. Encapsulation

Uru nke teknụzụ silicon na-ese n'elu n'efu bụ nrụrụ dị n'etiti silicon na molybdenum wafer nke ukwuu na-ebelata oriri molybdenum.Ọ bụ ezie na flatness nke silicon wafer na ọla kọpa ngọngọ nke ngwugwu na-ukwuu chọrọ ka myirịta na roughness chọrọ dị elu karịa alloying mgbawa technology.Site n'ịkwalitewanye na ihe ọhụrụ na-aga n'ihu, RUNAU Electronic emeriwo ihe isi ike na ihe mgbochi niile.Teknụzụ na-ese n'elu n'efu, thyristor voltaji dị elu nke nwere arụmọrụ a pụrụ ịdabere na ya na ngwọta azụmaahịa azụmaahịa ka emepụtara wee nye ndị ahịa.A na-etinye ọtụtụ n'ime ha na rectifier nke nwere ike ịchịkwa ike dị elu, ihe mmalite dị nro dị elu, nnyefe ike HVDC, traction locomotive, nkwụghachi ụgwọ ike na-arụ ọrụ ike na usoro ngwa ike pulse.
