18. A power equipment having a first connection pipe, and a pressure release plate made of an insulator, which is disposed within the first connection pipe in order to externally release a pressure that rises with occurrence of any abnormality within an enclosed container, wherein a high voltage conductor disposed within the enclosed container is supported by an insulator, comprising:
-
an antenna accommodation pipe in which an antenna is arranged, a second connection pipe which connects the antenna accommodation pipe and the enclosed container, a second signal detection device which is connected to the antenna and which detects a signal emitted when the abnormality has occurred within the enclosed container, and a partition plate made of an insulator, which transmits the signal at the occurrence of the abnormality within the enclosed container and which is disposed within the second connection pipe in order to partition the open air and the interior of the enclosed container. - View Dependent Claims (19)
