Device for the continuous assessment of the technical condition of power transformer in a connection into the power grid

摘要

in a device for continuous condition assessment of transformer energy zalaczenia conditions to the network.evaluation is performed by simultaneous measurement of tension ciagly przepiec laczeniowych and storm and values wzglednych tangent loss (tg?) and pojemnosci headquarters (cg) izolatora.the device has three insulators (iz1), (iz2), (iz3) przyporzadkowane phases tension network (l1), (l2), (l3) sprezone by adaptors (bs1), (bs2), (bs3) and factors pojemnosciowe (bd1), (bd2)(bd3) of track measuring tension przepiec (bpp) and tor measuring dielectric parameters (bpc) wyposazonym in blocks measuring pojemnosci headquarters (cg) and loss tangent measurement block (tg?) .exit tracks (bpp) and (bpc) are linked by network swiatlowodowe (s1), (s2) and (s3), (s4) of the measuring computer (pc).
