Solid-yakavharwa Pole Yazvino & Voltage Yakasanganiswa Transformers
Derating
Solid-sealed pole current uye voltage combination transformer inoshandiswa mu10kV distribution network feeders uye column switch, ine voltage level ye (10-35) kV uye frequency ye50Hz.
Danda rinobatanidza yazvino transformer, voltage transformer, vacuum interrupter, uye capacitive energy extraction device, inotora iyo APG process.Iyo yemukati yekuvharisa inodururwa ne epoxy resin mudanda rakasimba rekuvharisa, uye kunze kwekunze kunosungirirwa nesilicone yemvura, inobatanidza zvakanyanya. kekutanga neyechipiri.Sangana nezvinodiwa zvinoshanda zvemagetsi system metering, kuyerwa, nekudzivirira. Yakashongedzerwa nedhijitari module ADMU, danda rinogona kuburitsa chiratidzo chedhijitari kuburikidza nemodule,Siginecha yekuendesa kune terminal michina yakadai seFTU yakagadzikana uye yakarurama. miniaturization, kubatanidzwa uye digitalization yemidziyo yekutanga.Iyo yeperipheral chimiro chemidziyo inorerutswa, iyo yakachengeteka yekushanda nhanho yemagetsi emagetsi emagetsi inovandudzwa, uye kushanda nekugadzirisa zviri nyore.

Schematic
Isati yaiswa uye kutumirwa, bhuku iri rinofanirwa kunyatsoverengerwa kuti rinzwisise chimiro, hunhu uye kuita kwechigadzirwa ichi chisati chaenderera, uye kuchengetedzwa kunoenderana uye matanho ekudzivirira anofanirwa kutariswa mubasa.
∎ Transformer haibvumidzwe kutendeuka kana kupinduka panguva yekufambisa uye kurodha nekuburitsa, uye matanho ekuvhundutsa anodiwa.
■ Mushure mekusunungura, ndapota tarisa kuti pamusoro petransformer yakakuvadzwa here, uye kana zita rechigadzirwa nechitupa chekuenderana zvinopindirana nechinhu chaicho.
■ Kana iyo sensor iri pasi pekumanikidzwa, hwaro hunofanirwa kuve hwakavimbika pasi, uye inobuda lead inogona kumiswa, uye pfupi pfupi inorambidzwa zvachose.
■ The transformer pasi waya inofanira kunyatsodzika pasi panguva yekuisa.
∎ Sensor inofanirwa kuchengetwa mukamuri yakaoma, ine mhepo inofefetera, ine hunyoro-uchapupu, inovhundutsa uye inokuvadza gasi rinopinda mukamuri, uye chengetedzo yenguva refu inofanirwa kugara ichiongororwa kana nharaunda ichizadzisa zvinodiwa.
Kuraira Ruzivo
Paunenge uchiodha, ndapota nyora iyo chigadzirwa modhi, main tekinoroji paramita (yakatemerwa voltage, chaiyo nhanho, yakayerwa yechipiri paramita) uye huwandu.kana pane zvakakosha zvinodiwa, ndapota taura nekambani
