<p>PURPOSE:To prevent occurrence of an accident by installing a temperature detector in the oil chamber of an accumulator and stopping a hydraulic power plant when the temperature inside the oil chamber rises abnormally. CONSTITUTION:A hydraulic power plant is stopped when the temperature detected by a temperature defector 40 rises abnormally, while said temperature detector 40 being installed in the oil chamber of an accumulator 8. By means of such constitution, the hydraulic power plant can be protected from suffering from a fatal accident because shortage of effective consumption of oil due to expansion of the gas inside a bladder can be eliminated even through the ambient temperature around the spot of installation of the accumulator rises abnormally due to external factors or oil temperature rises abnormally due to some trouble in a pressure oil circulation system.</p> |
