Arrangement structure for power converter and control box in package-housed engine generator

Abstract

In a package-housed engine generator wherein an engine (10), a generator (11) driven by the engine, a power converter (14) that converts the generated power to a prescribed frequency, and a control box (17) that incorporates a control circuit board (16) for a radiator fan or another auxiliary part, are housed in a package (2), the control box and the power converter are arranged overlaid in that order in the inward direction relative to the open side of the package, and hinges (21) are provided on one edge of the control box to enable the control box to rotate.

Description

technical field [0001] The present invention relates to an arrangement structure of a control box and a power converter in a case-housing type engine-driven generator used in a cogeneration device and the like. Background technique [0002] At present, the case-housing type engine-driven generators used in combined heat and power devices, etc., house the engine in the case, the generator driven by the engine, the converter (power converter) that converts the generated power to a predetermined frequency, and the built-in heat sink. The control panel (control box) of the control board of the device such as the fan. [0003] Furthermore, the following disclosure discloses a structure in which such an engine, a generator, etc. are housed in a casing, and in order to improve the maintainability of the built-in equipment, the inverter is arranged in the rotary type at the lower part of the casing. Door (storage box) (for example, refer to Patent Document 1). [0004] Patent Docu...

Problems solved by technology

In this way, since the inverters and control panels are distributed on the side and front of the case, it is inconvenient to move the location when performing maintenance on these inverters and control panels at the same time.
