<p>PURPOSE:To obtain a gas pressure adjusting device for electric apparatus, which can detect an internal accident in the electric apparatus even in an operation of a compressor. CONSTITUTION:A pressure sensor 7 for detecting gas pressure P within an electric apparatus vessel 1, a control device 8 for generating an operation signal Q corresponding to the gas pressure, and an inverter 9 for driving a compressor 4 based on the operation signal are provided, and the compressor is driven without operating an impact pressure relay 6, so that gas for the electric apparatus vessel may be supplied and recovered.</p> |
