Chikumbiro:
•Rated simba: 112.5 kVA Kuburikidza ne15,000 kVA
•Yekutanga Voltage: 600V Kuburikidza ne35 kV
•Secondary Voltage: 120V Kuburikidza ne15 kV
Vacuum Pressure Impregnation (VPI) inzira yekuti ronda rakazara remagetsi emagetsi stator kana rotor inonyudzwa zvachose muresin. Kuburikidza nemusanganiswa wekuoma uye kunyorova vacuum uye kutenderera kutenderera, resin inofananidzwa mukati meiyo insulation system. Kana ichinge yaitwa thermally, iwo akabatanidzwa windings anova monolithic uye homogenous chimiro.
VPI yakaoma type transformers yakanakira akawanda maindasitiri uye ekutengesa maapplication. Aya ma transformer anopa yakanakisa mechanicha uye pfupi-redunhu simba, hapana njodzi yemoto kana kuputika, hapana zvinwiwa zvinodonha, huremu hushoma pane hunofananidzwa macoil units, yakaderera mutengo wevaridzi uye yakaderera yekutanga mutengo. Ivo vanoshandisa UL yakanyorwa 220°C insulation system, zvisinei nechiyero chekushisa. Kudzikira kuisirwa, kuchengetedza uye mari yekushandisa inoita kuti VPI shandurudzo ive yakasimba mari.
VPI matransformer haaputike nekupisisa murazvo uye haadi mavharita, madhishi emidziyo, kana masisitimu anodhura ekudzima moto.
Iyo VPI process
VPI transformer coils ndeye vacuum pressure yakamisikidzwa mune yakanyanya tembiricha yepolyester varnish. Maitiro acho anosanganisira kunyudzwa kwakazara muvarnish pasi pevacuum uye kumanikidzwa uye kwakagadziriswa kurapwa uchishandisa statistically process inodzorwa michina kuti ive nechokwadi chekuenderana.
Makoiri akapedzwa anodzivirirwa zvine hunyoro kubva kune hunyoro, tsvina, uye yakawanda inosvibisa maindasitiri. JIEZOU SIMBA's VPI matransformer anowanzo kukodzera kushandiswa mukati kana kunze uko vanhu vanoshanda nekufema.
A220℃Kirasi UL Yakanyorwa insulation system inoshandiswa paJIEZOU SIMBA's VPI transformers zvisinei neyakatsanangurwa tembiricha chiyero. Iyi sisitimu inogadzika tembiricha inokwira ye150℃. Optional tembiricha inokwira ye80℃uye 115℃uye kutonhora kwe fan kunobvumira kusaenzana kuwanda kwehuwandu.
VPI transformers inopa dhizaini kuchinjika uye inogara ichishandiswa kukwidziridzwa kwemagetsi uye retrofit dhizaini.
Core Kuvaka
VPI vashanduri vanoshandisa nhanho-pamakumbo mumitered musimboti kuvaka kuti ive nechokwadi chekuita kwakaringana uye kushoma inzwi mazinga. Iwo mitered musimboti majoini anobvumira yakanyatsoita flux kufambisa pamwe neakasikwa mitsara yezviyo pakati pemakumbo epakati nejoko. Kuvaka nhanho-yepakati kunowedzera kuwedzera kushanda kwekubatana nekudzikisa majoini, izvo zvinoderedza kurasikirwa kwepakati uye inonakidza ikozvino.
Iyo musimboti wakagadzirwa uye wakavakirwa kupa iyo yakaderera inobvira kurasikirwa kubva kumhedzisiro yemagnetic hysteresis uye eddy currents. Matanho ese anogoneka anotorwa kudzivirira matenderedzwa emunharaunda uye kudzivirira akavakirwa-mukati ekukotama kushushikana.
Iyo musimboti inogadzirwa kubva kune yakakwira permeability, inotonhora-yakakungurutswa, zviyo zvakanangana nesilicon simbi. Magnetic flux densities inochengetwa pazasi peiyo saturation point. Simbi yacho yakachekwa chaizvo kuti ivimbise kuti ichave yakatsetseka uye isina burr. Kuti riome uye ritsigire, majoko epamusoro neazasi akasungwa zvakasimba nenhengo dzesimbi dzinotsigira. Sunga mahwendefa anobatanidza kumusoro uye pasi mabhanhire uye anopa chimiro chakasimba chekusimudza.
Iyo yakapedzwa musimboti wakaputirwa necorrosion resistant sealant inopa lamination cohesion uye dziviriro yepakati kusvika kune yakaoma nharaunda.
Coil Kuvaka
Magadzirirwo emhepo haafanire kutsanangurwa kunze kwekunge paine zvinodiwa nemutengi. JIEZOU SIMBA inokwidziridza mhepo yekuvaka yekushanda voltage, basic impulse level, uye ikozvino kugona kweumwe neumwe mhepo.
Pese pazvinogoneka, matransformer anogadzirwa aine pepa ronda rechipiri windings uye waya ronda primary windings.
Kuvakwa kwemhepo kunogona kuve kwakatenderera kana rectangular kuburikidza ne2500 kVA yemakoiri eVPI. Windings paVPI transformers ine ratings yakakura kupfuura 2500 kVA anowanzo kutenderera.
JIEZOU SIMBA's low voltage VPI windings, insulation class 1.2 kV (600V) uye pazasi, anowanzo ronda achishandisa mapepa conductors. Ichi chivakwa chinobvumira kusununguka ikozvino kugoverwa mukati meaxial upamhi hwekoiri iyo inobvisa axial mauto akagadzirwa mune mamwe marudzi emhepo inoputika pasi pemamiriro mapfupi edunhu.
Iyo yekutanga coil inokuvadzwa zvakananga pamusoro pechipiri coil uye inoparadzaniswa neinodzivirira barriers. Aluminium conductors akajairwa nemhangura inopihwa senge sarudzo.
