Umhlahlandlela Wezihlangu Ze-Transformer Electrostatic (E-shields)

Iyini i-E-shield?
Isivikelo se-electrostatic siyishidi elincane elihambisa umoya elingenamagnetic. Isivikelo singaba yithusi noma i-aluminium. Leli shidi elincane lihamba phakathi kokugoba okuyinhloko nokwesibili kwe-transformer. Ishidi kukhoyili ngayinye lixhumanisa ndawonye nomqhubi oyedwa obopha ku-chassis ye-transformer.

Yini eyenziwa ama-E-shields kuma-transformer?
Ama-E-shields aqondisa kabusha ukuphazamiseka kwamandla kagesi okuyingozi kude nama-coil e-transformer kanye nama-electronics abucayi ezinhlelweni zikagesi. Lokhu kuvikela i-transformer kanye nohlelo oluxhunywe kuyo.
Ake sibheke lokhu ngokuningiliziwe siqale ngalokho okuvikelwa yi-E-shields.

Ukuncipha
Amasekethe amaningi kagesi anamuhla abhekene nokujikijela kwesikhashana nomsindo wemodi. Isivikelo se-E esisekelwe phansi sinciphisa (sinciphisa) lokhu kuphazamiseka.

Isithombe esingenhla ngakwesobunxele sibonisa ukuphakama okuvamile kwe-voltage yesikhashana. Lolu hlobo lokwanda okukhulu kwe-voltage yokunikezela luvela emishinini evamile yehhovisi efana namakhompyutha noma ama-photocopier. Ama-inverter nawo angumthombo ovamile we-spikes yesikhashana. Isithombe esingakwesokudla sibonisa isibonelo somsindo wemodi kusekethe kagesi. Umsindo wemodi uvame kakhulu kumasekethe kagesi. Izinhlelo ezinezintambo ezingasebenzi kahle ezinezivikelo zekhebula ezingafanele zivame ukuba nomsindo wemodi.
Manje ake sibheke ukuthi i-E-shield ibhekana kanjani nalezi ziphazamiso.

Ukuxhumanisa Okunamandla
Isivikelo se-E esisekelwe phansi sinciphisa ukuxhumanisa okunamandla phakathi kokugoqana kokuqala nokwesibili. Esikhundleni sokuxhumanisa nokugoqana kwesibili, ukugoqana kokuqala kuhambisana nesivikelo se-E. Isivikelo se-E esisekelwe phansi sinikeza indlela ephansi yokuvimbela ukuya phansi. Ukuphazamiseka kwe-voltage kudluliselwa kude nokugoqana kwesibili. Lokhu kusebenza futhi kusukela kolunye uhlangothi lwe-transformer (okwesibili kuya kokwesibili).

Izipikili zesikhashana nomsindo wemodi kungalimaza ama-transformer kanye neminye imishini kagesi. Isivikelo se-electrostatic phakathi kwamakhoyili e-voltage ephezulu kanye ne-voltage ephansi kunciphisa izingozi ezinjalo. Okubalulekile okufanele kucatshangelwe lapho kuhlinzekwa amandla kuma-electronics abucayi.

Izibonelo Zama-Transformers Asebenzisa I-E-shield
Ama-Solar & Wind Transformers
Ukuphazamiseka kwe-Harmonic kanye nokushintsha okukhethekile okuvela kuma-inverter elanga kudluliselwa kugridi yokusetshenziswa. Lokhu kuphazamiseka kwe-voltage kudala imiphumela efana ne-impulse ku-HV winding ephakela igridi. Ama-spikes e-overvoltage esikhashana ohlangothini lokusetshenziswa angadlulela naku-inverter. Lezi zenzakalo ze-overvoltage zingalimaza izingxenye ezibucayi ze-inverter. Ama-E-shields ahlinzeka ngokuvikelwa kokubili ku-transformer, kugridi, kanye naku-inverter.
Funda kabanzi mayelana nosayizi we-solar transformer kanye nezidingo zomklamo.

Shayela Isiguquli Sokuzihlukanisas
Ama-transformer okuhlukanisa ama-drive akhiwe ukuze amelane nokuphazamiseka kwe-voltage ephezulu (ama-harmonics). Ukuphazamiseka okunjalo kuvela emishinini efana nama-motor drive (noma ama-VFD). Ngakho-ke igama elithi "drive" egameni. Ngaphezu kwama-harmonics, ama-motor drive angase aveze nezinye izinkinga ze-voltage (njengomsindo wemodi). Yilapho i-E-shield iqala khona ukusebenza. Ama-transformer okuhlukanisa ama-drive afaka okungenani i-E-shield eyodwa phakathi kwama-HV nama-LV coil. Kungasetshenziswa nezihlangu eziningi. Ama-E-shields angabekwa phakathi kwama-inner coils kanye ne-core legments.
Izinhlelo zokusebenza ezinezinkinga ze-voltage (njengezipikhi zesikhashana nomsindo wemodi) ziyazuza ku-transformer ene-E-shield. Ama-E-shields ashibhile, futhi anikeza imbuyiselo ebalulekile ekutshalweni kwezimali lapho izinkinga zekhwalithi yamandla ziyingozi.
