Abstract
A bushing tank having power receiving lead-in bushings of three phases to which conductor portions extended rearward of a main body portion in which a switching device is housed are connected is included, and the power receiving lead-in bushings of the three phases are disposed at an upper surface portion of the bushing tank at equal intervals in a circumferential direction such that end portions thereof are inclined outward so as to be separated from each other, and one of the power receiving lead-in bushings of the three phases is disposed along a front-rear direction of the main body portion. Owing to this configuration, it is possible not only to ensure insulation distances between the end portions of the power receiving lead-in bushings but also to ensure insulation distances between lead-in wires regardless of a power receiving lead-in direction.
