 Quick Detail: 220kV 110kV 66kV Three-phace two winding on-load-tap-changing power transformer

General EACHER brand 22DKV, 110kv and 66kv low-loss senes transformer is our independendy developed new generaton of transtormers on the basis or absorption of domestic and foreign advanced technology wh ich features ow local discharge, low loss, low noise, high reliability, strong protection against abrupt circuit. Its excellent per formance has been recognced by wide users and highly appra sed by experts, The full-sealed suspending-cover fee products sel well nationwide Amount of local discharge. The apparent discharge amount under 1.5 tmes of rated voltage is less than 80pc.
Noise; Products of 63MvA and below is ower than 58cB(AN Power los5: no-load loss is 30%o lower than that of IEc standard Reliability: All in-service products have no damages or od leakage occurred: short arcut withstanding: Model SFZ11-50000/132 smoothly passed the short-circut withstanding test of the national transformer quality supervision and nspection center and aso passed Holland"KEMA"qualty Control systom
 

Coil The high-voltage (HV) coil adopts an interleaved -cominuous structure to imp rove the voltage characteristics under impact voltage and make voltage evenly dstributed All stays and pads are chamfered to keep highly reliable insulation In the trans former winding there is a z gzg oil guide structure so as to fully cool al areas ins de the winding, lower the temperature rise of the winding and he hot points of the winding and prolong the service ife of insulaton The Hv and Mv regulation system are independendy pron ded with voltage-requlabing wnang to balance the ampere tum of each winding, efectively lower the axia ele trod ynamic torce generated at short cireuit of transformer and mprove abru short-circuit withstand ing capadty he wnding adopts radial"margin design, between the core and the paper sleeve of LV winding, and between the Lv, HV voltage regu ating wind nos as well as before insertion of stays and shroud plate they are fuly aned and tighty matched to ensure extremely good compactness and ooncentnaty af the entire winona

Core The core is made of hig-permeable gran-onentated top qualty ocid-roled silicon sheet and the matenal is cut with advanced Gemany Geoge GmbH automatic shear line with the cut burrs controlled within 0. 02mm The silicon sheet fabrication adopts"no-upper yoke-lapped"technology and all lapped joints of the silicon sheet are 45 full-miters, The laminated core she ets are integraly pressed and adhered with epoxy resin to make the three-leg two-yoke core a strong and flat integral one with good verticality preasion, this effectiv ely impx owes no-load performance an reduces noise Bracing plates are used as support between coil leg and nner coil The iron yoke is tied with epoxy resin-impre gnated dass hber band, and the lowe yoke and the lower section of cil tank is tightened with counter-pressure bots. The upper iron yoke and the upper section of oil tank are fixed at 3
locations. Hence the body inside tho oil tank can withstand the vibration during transportation witho ut any shift.

Oil tank and accessories The tank wall adopts wide steel sheet, which wil be folded into corrugated structure without splicing, in this way welds are decreased and me chani cal strength is enhanced; meanwhile, the corrugated wall has diverging effect, and thus plays a role in de crease of noise. The routing troughs and control cabinets of the secondary circuit are all made of stainless steel, so the entre trans former has a simple and good lookng All sealing surfaces use quality sealing matenal and are precision-
machined On the edge of the tank there are double sealing grooves and the outer sealing material is used to shade the atmosphere and ultra-ray to protect the inner sealing being damaged, thus at utmost prolonging service life and enhancing reliability ofthe seal.
