A rotating electrical machine includes: a rotor; a stator; a high voltage bushing; power lines connecting the stator coil to the bushing; a support insulator that supports the power lines; a rotating electrical machine outer casing that contains at least the rotor, the stator and a connection portion between the stator coil and the power lines, and is filled with hydrogen gas; and a terminal box which communicates with the outer casing and is attached to a lower portion of the outer casing, the insulator installed in the terminal box, and terminal box containing at least the power lines supported by the insulator and a part of the bushing connected to the supported power lines. The insulator is installed vertically on a bottom face of the terminal box, and the vertically installed insulator and a portion of the bushing in the terminal box are disposed in parallel with each other.

Rotating electrical machine

A PCS comprises a DC/DC convertor that converts a voltage of a DC power input from a solar cell; an inverter that converts the DC power to an AC power; and a controllerthat stops an operation of the DC/AC convertor without stopping the inverter when a condition that stops an output of the solar cell is satisfied.
