Grounding Transformers
Grounding transformers tuaj yeem muab txoj hauv kev hauv av rau qhov tsis muaj av lossis siv tau thaum lub kaw lus nruab nrab tsis ua haujlwm thiab ua tsis tau.
Yog vim li cas rau kev ntiav ib tug grounding transformer (los yog) nws functionality yog raws li nram no:
Thaum lub transformer yog grounded, txo qhov magnitude ntawm transient overvoltage.
Muab ib txoj hauv kev uas tsis tshua muaj impedance grounding rau transformer xws li qhov system qhov nruab nrab ntawm qhov tseem nyob los yog ze rau hauv av.
Muab qhov chaw tam sim no thaum muaj kab hauv av tsis ua haujlwm.
Hauv cov xwm txheej tshwj xeeb, txuas ib theem - nruab nrab load.

Vim li cas thiaj xaiv LTEC'sGrounding Transformers?
LTEC - Tsim koj lub zog nrog kev tsim kho tshiab!
Core Function: daws qhov teeb meem tseem ceeb ntawm kev nyab xeeb thiab qhov system
Tsim Ib Qhov Chaw Nruab Nrab:Nyob rau hauv ungrounded los yog delta -kev sib txuas tshuab, tsis muaj qhov nruab nrab. Ib qho kev hloov pauv hauv av (feem ntau yog Zig-Zag lossis Wye-Delta) tsim ib qho.
Muab Ib Txoj Kev rau Av Fault Tam Sim No:Thaum lub sij hawm ib theem - mus rau - hauv av txhaum, nws muab txoj hauv kev qis - impedance rau qhov txhaum tam sim no rov qab los, tso cai rau cov relays tiv thaiv kom pom thiab tshem tawm qhov txhaum sai.
Limit Transient Overvoltages:Los ntawm stabilizing lub kaw lus nruab nrab, nws tiv thaiv kev puas tsuaj overvoltages uas tuaj yeem tshwm sim hauv cov tshuab tsis muaj av thaum lub sij hawm arcing av faults.
Qhov tseem ceeb sib txawv ntawm LTEC
Daim ntawv thov -Specific Designs:LTEC tsis muaj ib qho - loj - haum - tag nrho cov kev daws teeb meem. Lawv engineers transformers raws li koj qhov system voltage (piv txwv li, 4.16kV, 13.8kV, 33kV), txhaum cai tam sim no, thiab kev txwv lub cev.
Advanced Modeling:Lawv siv cov software tsim nyog los ua qauv kev ua tau zoo nyob rau hauv ntau yam kev ua txhaum, kom ntseeg tau tias lub tshuab hloov pauv yuav coj raws li qhov xav tau hauv qhov tiag -kev ua txhaum hauv ntiaj teb.
Optimal Impedance Tsim:Lub impedance yog ua tib zoo xam los txwv lub hauv av txhaum tam sim no mus rau theem siab txaus rau relays mus ntes tab sis tsawg txaus los tiv thaiv kev puas tsuaj rau cov khoom (feem ntau nyob rau hauv 200A mus rau 1000A ntau).
Kev tsim kho thiab cov khoom siv zoo
High -Quality Core Steel:Siv qis- poob, nplej- taw qhia silicon steel rau kev ua haujlwm zoo sib nqus thiab txo cua sov.
Lub zog Copper Windings:Feem ntau siv tooj liab windings rau superior luv luv - Circuit Court withstand peev, thermal kev ua tau zoo, thiab corrosion kuj piv rau txhuas.
Rigorous rwb thaiv tsev System:Nta lub tshuab nqus tsev siab impregnated (VPI) los yog cam khwb cia resin rwb thaiv tsev system. Qhov no ua rau cov windings tiv taus cov dej noo, tshuaj lom neeg, thiab ib puag ncig cov kab mob, uas yog qhov tseem ceeb rau kev cia siab rau lub sijhawm ntev.
Robust Tank thiab Finish:Lub tank feem ntau yog ua los ntawm hnyav dua - ntsuas cov hlau thiab tiv thaiv siab - cov xim zoo nkauj lossis epoxy txheej los tiv thaiv corrosion nyob rau hauv ib puag ncig hnyav.
