Abstract

PURPOSE:To enable miniaturization and lightening by composing the titled transformer of a main transformer section formed by winding high voltage and intermediate voltage winding on a core main leg and a LVR section, an auxiliary core leg thereof is provided with exciting winding connected in parallel with low voltage winding and shunt section winding and which has a tap changer. CONSTITUTION:The main transformer section 10 consists of series winding 1 wound on the core main leg, shunt main winding 2A, which is connected to the neutral point side and a node thereof reaches an intermediate voltage point, and tertiary winding from which tertiary terminals (a), (b) are drawn. The LVR (a voltage regulator at the time of load) section 20 is equipped with the shunt section winding 23, 24 wound on the auxiliary core legs, tap winding 51, 52, which are connected to each neutral point side of these shunt section winding through the switching switches 61, 62 of the tape changer 30 at the time of load and are used inparallel, and the excitng widing 4, which is connected in parallel with the tertiary winding 3, the winding at the low voltage side of the main transformer section 10, and excites the shunt section winding 23, 24 and the tapped winding 51, 52. The titled transformer is formed in such as manner that it is changed over by means of tap selectors 71, 72 and switching switches 81, 82 and reaches a neutral point terminal 0.
