Ubuyobozi bw'Inkingi z'amashanyarazi zihindura ikirere (E-shields)

E-shield ni iki?
Uburinzi bw'amashanyarazi ni urupapuro rworoshye rudakoresha ingufu za rukuruzi. Uburinzi bushobora kuba umuringa cyangwa aluminiyumu. Uru rupapuro rworoshye rujya hagati y'impande z'ibanze n'iz'inyongera za transformateur. Uru rupapuro ruri muri buri coil ruhuzwa n'umuyoboro umwe ufatana na chassis ya transformateur.

Ni iki e-shields zikora muri transformers?
E-shields ziyobora amashanyarazi yangiza kure y’imiyoboro ya transformer n’ibikoresho by’ikoranabuhanga byoroshye biri mu buryo bw’amashanyarazi. Ibi birinda transformer n’uburyo ihujwe nayo.
Reka tubirebe neza duhereye ku cyo E-shields zirinda.

Kugabanya ubushobozi bwo kugabanya
Insinga nyinshi z'amashanyarazi zigezweho zihura n'ibibazo by'ingufu z'igihe gito n'urusaku rw'uburyo. E-shield ihagaze igabanya (igabanya) ibyo bibazo.

Ishusho iri hejuru ibumoso igaragaza ukwiyongera gusanzwe kwa voltage idahoraho. Ubwo bwoko bw'ubwiyongere bukabije bwa voltage itangwa buturuka ku bikoresho bisanzwe byo mu biro nka mudasobwa cyangwa ibyuma bifotora. Inverters nazo ni isoko rusange ya spikes idahoraho. Ishusho iri iburyo igaragaza urugero rw'urusaku rw'uburyo mu muyoboro w'amashanyarazi. Urusaku rw'uburyo rukunze kugaragara mu miyoboro y'amashanyarazi. Sisitemu zidakora neza zifite uburinzi bw'insinga butari bwiza akenshi zigira urusaku rw'uburyo.
Noneho reka turebe uburyo E-shield ikemura ibi bibazo.

Guhuza ubushobozi
E-shield ifite imiterere y'ubutaka igabanya ubushobozi bwo guhuza hagati y'imizunguruko y'ibanze n'iya kabiri. Aho guhuza n'imizunguruko y'ibanze, imizunguruko y'ibanze ihuza na E-shield. E-shield ifite imiterere y'ubutaka itanga inzira yoroshye yo kwinjira ku butaka. Ihindagurika ry'amashanyarazi rijyanwa kure y'imizunguruko y'ibanze. Ibi kandi bikora ku rundi ruhande rwa transformateur (iy'ibanze ijya ku y'ibanze).

Utuzu duto tw’amashanyarazi n’urusaku rw’amashanyarazi bishobora kwangiza transfoma n’ibindi bikoresho by’amashanyarazi. Uburinzi bw’amashanyarazi hagati y’amashanyarazi menshi n’amashanyarazi make bigabanya izo ngaruka. Ni ikintu cy’ingenzi cyo kuzirikana mu gihe cyo gutanga ingufu ku bikoresho by’ikoranabuhanga by’ikoranabuhanga.

Ingero za Transformers zikoresha E-shield
Transformers z'izuba n'umuyaga
Guhungabana kwa harmonic no guhinduranya byihariye bivuye kuri inverters z'izuba byimurirwa kuri grid y'amashanyarazi. Uku guhungabana kwa voltage bigira ingaruka nk'iz'ingufu mu mizunguruko ya HV igaburira grid. Imiterere ya overvoltage y'igihe gito ku ruhande rw'amashanyarazi ishobora no kwerekeza kuri inverter. Ibi bintu bya overvoltage bishobora kwangiza ibice by'ingenzi bya inverter. E-shields zirinda transformer, grid, na inverter.
Menya byinshi ku bijyanye n'ingano ya transformer y'izuba n'ibisabwa mu gishushanyo mbonera.

Gutwara Transformer yo kwitandukanyas
Transformateur zo kwimura imodoka zubatswe kugira ngo zihangane n’ihungabana ry’amashanyarazi rikabije (harmonics). Ihungabana nk’iryo rituruka ku bikoresho nka moteri (cyangwa VFDs). Bityo ijambo "drive" mu izina. Uretse harmonics, moteri zishobora no guteza izindi hungabana ry’amashanyarazi (nk’urusaku rw’uburyo). Aha niho E-shield igaragara. Transformateur zo kwimura imodoka zirimo nibura E-shield imwe hagati ya HV na LV coils. Hari kandi n’ingabo nyinshi zishobora gukoreshwa. E-shields zishobora gushyirwa hagati ya coils z’imbere n’ingingo z’imbere.
Porogaramu zifite imvururu z’amashanyarazi (nk’imivuduko y’amashanyarazi ihoraho n’urusaku rw’uburyo) zungukira kuri transformateur ifite E-shield. E-shields zirahendutse, kandi zitanga inyungu nini ku ishoramari aho ibibazo by’ubuziranenge bw’amashanyarazi ari ikibazo.
