1 MVA Milestone: Robustness & Reliability

Cov1000 kVA Qhuav Hom Transformersawv cev rau "tus qauv kub" muaj peev xwm rau lub tsev loj lub zog thiab hnyav kev lag luam feeders. Nws cim qhov kev hloov pauv mus rau hauv chav kawm megawatt, qhov twg lub cev muaj zog ntawm cov windings yuav tsum tau ua kom zoo dua qub engineering.

Raws li qhov siab - muaj peev xwmPeb theem qhuav hom transformer, chav tsev no yuav tsum tiv thaiv lub cev "magnetic rauj" cuam tshuam ntawm luv luv Circuit Court. Txhawm rau lav qhov no, peb siv aHnyav-Lub Luag Haujlwm Channel Steel Ncej. Tsis zoo li cov me me uas tso siab rau txoj hlua khi yooj yooj yim- cov pas nrig, 1 MVA qauv no siv cov hlau txuas sab saud thiab qis los txhawm rau txhawm rau cov coils zoo li lwm tus. Qhov rigidity no tiv thaiv cov windings los ntawm telescoping los yog hloov thaum lub sij hawm hluav taws xob faults, tiv thaiv kev puas tsuaj rau txhua yam tsis ua hauj lwm.

Cam khwb cia Resin Technology: Silica Ratio

Lub neej ntev ntawm 1000 kVA chav nyob yog nyob ntawm qhov zoo ntawm nws cov rwb thaiv tsev sib tov. Peb siv tus nqi themqhuav hom cam khwb cia resinsystem uas ua hauj lwm zoo li engineered pob zeb dua li yas.

Kev sib xyaw:Peb sib tov epoxy resin nrog ib tug siab concentration ntawmQuartz Silica hmoovhauv qab lub tshuab nqus tsev. Qhov no tsis yog rau rwb thaiv tsev xwb; cov silica ntxiv cov khoom siv dag zog loj heev.
Kev Tiv Thaiv Kev Txhaum Cai:Vim tias qhov sib xyaw no tau hloov kho kom muaj cov thermal elongation zoo ib yam li tus neeg xyuas pib tooj liab, lub rwb thaiv tsev txav mus.nrogcov hlau, tsis tawm tsam nws. Qhov no txhais tau hais tias lub kauj tseem ruaj khov thiab tawg -dawb, txawm tias lub tsev tau cua sov sai los ntawm qhov pib txias (-25 degree) mus rau kev ua haujlwm puv.

Kev Tso Tawm Ib Feem & Hluav Taws Xob Kev Noj Qab Haus Huv

Rau 10 kV lossis 11 kVtransformer qhuavhom rwb thaiv tsev system, "Partial Discharge" (PD) yog qhov ntsuas ntsiag to ntawm rwb thaiv tsev tsis ua haujlwm.

Standard:Thaum cov qauv kev lag luam feem ntau tso cai rau txog li 20pC (pico-Coulombs) tawm, peb 1000 kVA coils raug pov rau hauv lub tshuab nqus tsev nruj kom tiv thaiv huab cua voids.
Qhov tshwm sim:Peb lav aPartial Discharge theem ntawm<10 pC. Qhov tshwj xeeb tus nqi qis no qhia tau tias tsis muaj dab tsi - cov khoom rwb thaiv tsev tsis pub dawb, kom ntseeg tau tias cov khoom siv dielectric tsis maj mam eroding los ntawm sab hauv tawm, uas yog qhov tseem ceeb rau siab - cov cuab tam muaj kev ntseeg siab xws li tsev kho mob mains lossis cov ntaub ntawv chaw pub khoom.

Cov ntsiab lus ntawm Daim Ntawv Thov

Public Infrastructure:Fais fab metro chaw nres tsheb lossis tshav dav hlau terminals uas cov pa luam yeeb tsawg (F1) thiab tsis yog - cov khoom tawg yog qhov yuav tsum tau ua kom muaj kev nyab xeeb rau cov neeg caij tsheb.
Cov nroj tsuag muaj:Muab tso rau hauv qhov chaw tsim khoom "qhuav" (piv txwv li, cement lossis textile mills). Cov khoom resin nto yog du thiab tsis yog - taug qab, tso cai rau cov plua plav ua kom yooj yim tshem tawm thaum lub sijhawm ua haujlwm kaw.
Sab hauv tsev substations:Hloov cov roj hauv cov chav tsev hauv qab daus kom tshem tawm qhov kev pheej hmoo ntawm hluav taws thiab xav tau cov roj kim heev -catchment civil tej hauj lwm.
