Niki kibuza gusenyuka kwa dielectric mumashanyarazi ya Lacquered Multi-Layeri Foil Insulation Blankets munsi ya Tesla 10?

Iterambere mpuzamahanga ryerekeza ku bikorwa remezo birenga ibikorwa remezo byihuta ku buryo butigeze bubaho. Kuva mu bucuruzi bwa kirimbuzi bwa kirimbuzi (nka tokamaks yo mu rwego rwo hejuru na tokamaks na stellalers) hamwe n’ibisekuruza bizaza byihuta kugeza ku mashusho y’ubuvuzi bwa ultra-high-field (11.7T + MRI) hamwe na gride yo gutwara abantu ya Maglev, ubukungu bwigenga bushora imari cyane muri sisitemu ya rukuruzi ya Tesla.

Imbere muri sisitemu zifite ingufu nyinshi, ibishishwa birenze urugero bikora ku bushyuhe bwa kirogenike bwarohamye muri helium y'amazi cyangwa se imbaraga zidasanzwe za helium. Kugabanya imbaraga za firigo, ibiringiti byinshi (MLI) bikingira ubukonje. Ariko, gukorera mumashanyarazi arenga 10 Tesla bizana ingaruka zikomeye zamashanyarazi nubukanishi: iterwa nigihe gito cya dielectric.

Mugihe cyihuta cya magnetiki yihuta, ibikorwa bya plasma byakozwe, cyangwa gusohora ibintu bitunguranye byihuta (kuzimya), impinduka zihuse mumashanyarazi ya magnetique itera imbaraga zinzibacyuho zinzibacyuho zambukiranya ibice bifatanye. Mubisanzwe bisanzwe bitarinze gukingirwa cyangwa ibiringiti bikingiwe nabi, iyi voltage irenze igipimo cya dielectric kumeneka yumwanya wa vacuum. Amashanyarazi yavuyemo yatwitse pinholes binyuze kuri fayili, asudira ibice byegeranye mu ikabutura y’umuriro, kandi atera kuzimya magnet yiruka bishobora gutera amamiriyoni y’amadolari yangiza ibikoresho ndetse nigihe cyo gukora.

Lacquered nyinshi-aluminiyumu foil insulasiyo yuburiri itanga uburinzi bwuzuye bwinganda. Muguhuza ibishishwa bya aluminiyumu yuzuye (1000 na 8000) hamwe na sub-micron, dielectric yambukiranya-ihuza polymer-ceramic barrière lacquers , ibi bikoresho bitanga imbaraga nyinshi zo gusenyuka kwa dielectric, bikumira ibyuka bitangiza, bikuraho ibicuruzwa, kandi bikagabanya ibiciro bya MLI byo guhimbira hamwe na firime-hamwe na firime..

Imiterere yuburyo bwa Aluminium Foil-Yera

Imirasire ya Cryogenic yumuriro ikorera munsi yumurima wa magneti isaba ibintu bifatika na magneti:

Ububiko-Bwinshi 1085 & 8011 Ububiko bwibanze: Ubuziranenge bwa aluminiyumu burenga 99,85% butanga ubuso buhebuje, busa neza butarimo icyuma-silicon intermetallic intermetallic ishobora kuba nkibintu byibanda kumashanyarazi.

Ibitari Magnetique, Eddy-Ibiriho-Kugenzurwa Ibipimo: Aluminium ntabwo ari magnetique, irinda kugoreka magnetiki kumurima wa mbere wa Tesla. Ibipimo bito cyane (kuva kuri microne 12 kugeza kuri microne 50) igice cyumuhanda wogutwara amashanyarazi, bikagabanya cyane ubushyuhe bwa eddy-bigabanya no kugabanya ingufu za Lorentz zikoreshwa mugihe cyihuta cyumurima.

Imyunyungugu ya Cryogenic Kugera kuri 4 Kelvin: Bitandukanye na ferritic alloys cyangwa firime ceramic yamenetse ivunika munsi yumuriro wumuriro wa kirogenike, aluminiyumu yo mu maso ya cubic hrustal lattice irakomera kandi igakomeza kurambura kugeza kuri zeru rwose, ikurura ibinyeganyezwa bya mashini nta gucika intege.

Sub-Micron Yibanze-Dielectric Lacquer

Umwanya wa anodizing cyangwa urekuye icyogajuru cya plastike birananirana mumashanyarazi yihuse. Urupapuro rwambere rwa lacqued foil rukoresha ubudahwema, uruganda rwakize inzitizi:

Polyrix-Ceramic Hybrid Matrix: Yakozwe muri organosilicon cyangwa yahinduwe na polyimide-ceramic, igipfundikizo gitanga imbaraga zidasanzwe zo gusenya dielectric (zirenga 25 kV kugeza 35 kV kuri milimetero yubugari) mugihe hasigaye micro-yoroheje (mubisanzwe mikoroni 0.5 kugeza 1.5).

Igenamigambi ridafite ubusembwa: Amazi ya coil yamazi atembera hejuru ya microscopique izunguruka kumurongo wa foil mbere yo gukira ubushyuhe, koroshya imiterere yubuso no gukuraho impinga ya microscopique ikurura imyuka yangiza imyanda.

Ibibazo

Q1: Kuki umurima wa magneti 10 wa Tesla utera amashanyarazi mumashanyarazi menshi?

Igisubizo: Mugihe cyihuta cyumurima cyangwa kuzimya magneti byihutirwa, ihinduka ryihuse rya magnetiki flux itera imbaraga zinzibacyuho ndende hejuru yimpapuro zegeranye. Mubidukikije bya vacuum ya kirostat, ubwo bushobozi bwamashanyarazi burenze byoroshye gusenyuka kwamashanyarazi yumwanya wa vacuum, bigakora imiyoboro yamashanyarazi ishonga umwobo unyuze muri fayili ikanakora ikabutura yumuriro.

Q2: Nigute lacquer ya sub-micron irinda gusenyuka kwa dielectric kurwego rwa file?

Igisubizo: Uruganda rukoreshwa na lacquer rugizwe na bariyeri yuzuye ya dielectric idasanzwe, hejuru ya aluminiyumu. Hamwe n'imbaraga za dielectric zirenga 25 kV / mm, iyi coating ikomeye irinda imyuka ya elegitoronike na ionisiyoneri ndetse no mumashanyarazi ya voltage, guhagarika imiterere ya arc mbere yuko ikuraho icyuho.

Q3: Ese lacquer ya dielectric iracika cyangwa igishishwa iyo ikonje kugeza ubushyuhe bwa helium (4 Kelvin)?

Igisubizo: No. Ihanganira ihungabana ryihuse ryubushyuhe kuva mucyumba cyo hasi kugeza kuri 4 Kelvin itavunitse, itanyeganyega, cyangwa ngo isibe.

Q4: Nigute fayili ya lacage igabanya igiciro cyakazi cyo guhimba ibiringiti bya kirogene?

Igisubizo: Ibiringiti bisanzwe bya MLI bisaba abatekinisiye guteranya intoki zindi zisimburana zambaye ubusa hamwe ninshundura za polymer spacer inshundura kugirango birinde amashanyarazi. Ifarashi yabanjirije iyinjizwamo insimburangingo ya dielectric hejuru yicyuma, ituma ibice byapakirwa kandi bikazenguruka bitarimo inshundura zitandukanye, bigatuma imirimo yo guterana irenga 50%.

Q5: Kuberiki uhitamo fayili ya aluminiyumu hejuru ya myumin ya aluminiyumu ya magneti yo hejuru cyane?

Igisubizo: Mylar ya aluminiyumu ikoresha intungamubiri ya plastike itesha agaciro, ikinjira, hamwe na flake munsi ya radiyo ya neutron na gamma, mugihe ikanarenza ibinyabuzima kama bihindagurika mumyuka myinshi. Ifumbire ya aluminiyumu yuzuye hamwe na lacquer ya organic-hybrid ni imirasire-ikomeye, ntisohoka, kandi ihagaze neza mumashini mumyaka mirongo ikomeza ikora ya rukuruzi.

Umwanzuro

Kurandura dielectric gusenyuka no kugwiza inteko nyinshi kumurongo utaha wo murwego rwo hejuru-superconducting magnet umushinga:

Tegeka 100% In-Line Icyemezo cyo Kwipimisha Icyemezo: Saba ibyangombwa byo kugura kugirango wemeze ko buri metero kare ya stock ya coil yatsinze ikizamini cyikomeza kidasenya kuri 1000V DC cyangwa irenga, byemeza ko zidafite imiyoboro ya zeru.

Kugaragaza imbaraga zemewe za Cryogenic Dielectric (> 25 kV / mm): Menya neza ko ibyangombwa bitanga isoko bigenzura ibipimo bya dielectric yamashanyarazi munsi ya azote yuzuye (-196 ° C) hamwe nubushyuhe bwimbitse kugirango umutekano wifashe mugihe cyo kuzimya magneti 10 ya Tesla.

Hitamo Gauge na Lacquer Ubunini bushingiye kuri Winding Tension: Kugaragaza fayili ya micron 15 kugeza kuri 25 hamwe na 1.0 micron lacquer layer ya automatike yimyenda myinshi yizengurutsa izengurutswe na coil end end, kugirango ihindurwe neza idafite micro-crazing.
