<p><P>PROBLEM TO BE SOLVED: To provide an engine generator capable of automatically preventing a high voltage from being output to a single-phase, three-wire output terminal when the output of the generator is in a high voltage state. <P>SOLUTION: The portable engine generator includes a voltage setter for switching an output from the synchronous generator driven by an engine to an output terminal block between a high-voltage output and a low-voltage output and a single-phase/three-phase setter for switching it between a single-phase output and a three-phase output. The engine generator further includes a first detector (first relay RY1) for detecting that the setting of the single-phase/three-phase setter is a single-phase output, a second detector (second relay RY2) for detecting that the setting of the voltage setter is a high-voltage output, and an output stopper (breaker trip coil TC) for stopping the output to the output terminal block when the first detector detects a single-phase output state and the second detector detects a high-voltage output state. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
