The utility model discloses a novel integrated high-voltage standard voltage transformer. The novel integrated high-voltage standard voltage transformer comprises coils, wherein the coils are formed by a primary winding and a secondary winding, the primary winding and the secondary winding are wound on an R-shaped iron core, and the secondary winding is a secondary winding with a tap. The number of turns of the primary winding and the number of turns of the secondary winding are determined according to a 220kV stand voltage transformer, the number of turns of a secondary winding of a 110kV standard voltage transformer is determined according to the number of turns of the secondary winding, and the number of turns of the secondary winding of the 110kV standard voltage transformer is two times that of the secondary winding of the 220kV standard voltage transformer. The novel integrated high-voltage standard voltage transformer can measure the 110kV standard voltage transformer and the 220kV standard voltage transformer at the same time, the number of measuring devices is reduced, and frequent replacement of the devices is not needed in the process of testing. Due to the fact that the R-shaped iron core made of materials with the high magnetic flux density and the low loss is adopted, a magnetic path is good, stability is good, insulation and distribution uniformity of electric fields are taken into consideration by the design of the coils, flux leakage is low, the accuracy class can reach the 0.01 class.
