Abstract

PURPOSE:To effectively control an increase in temperature in a sound-proof wall without missing sound-proof effect by providing a cooling piping in the space at the upper part in the sound-proof wall wherein the cooling pipe and oil pipelines are connected by connecting pipes. CONSTITUTION:A transformer 1 is surrounded by a sound-proof wall 3. And an oil tank 2 and a cooling device 4 provided at the outside of the sound-proof wall 3 are connected by oil pipelines 5 and cooled oil is circulated by an oil-feeding pump P. A cooling pipe 10 is provided in the space at the upper part of the transformer 1 in the sound-proof wall 3. The pipe 10 is connected to the oil pipelines 5 at feeding side and discharge side respectively by connecting pipes 11, 12 and oil is simultaneously sent to the pipe 10 when the cooled oil cooled by the cooling device 4 is sent into the oil tank 2 by the pump P. In this way, the space in the wall 3 is cooled.
