Abstract

PURPOSE:To effectively control an increase in temperature in a sound-proof wall without missing sound-proof effect by providing a cooling pipe at the space at the upper part in the sound-proof wall wherein the cooling pipe is connected to an exclusive cooler provided at the outside of the sound-proof wall. CONSTITUTION:A transformer is surrounded by a sound-proof wall 3. And an oil tank and a cooling device 4 provided at the outside of the sound-proof wall 3 are connected by oil pipelines 5 and cooled oil circulated by an oil-feeding pump P. And a cooling pipe 10 is provided at the space at the upper part of the transformer in the sound-proof wall 3. The pipe 10 is connected to an exclusive cooler 13 for the space at the inside of the sound-proof wall 3 provided at the outside of the sound- proof wall 3 by connecting pipes 11, 12 and a cooling medium is sent to the oil tank by the pump 1 provided at the connecting pipe 11. In this way, the space in the sound-proof wall 3 is cooled up to a predetermined temperature.
