摘要： PROBLEM TO BE SOLVED: To provide a suctioning pipe of a hydraulic machinery which can reduce an excavation amount for embedding the suctioning pipe, suppress a leakage amount of high pressure air for pressing down water level during idling operation, and eliminate uneven distribution of velocity of water flowing into a runner during operation of a pump. SOLUTION: A lower reference point 9 is set on a lowermost point of a contour line of an upper cut sectional area being contact with a flow passage, in the case that an elbow suctioning pipe 6 is cut by a perpendicular surface passing the center of its flow passage. The lower reference point 9 is located on a position lower than a lower end of a runner 3 by length more than twice of that an outlet diameter DC of the runner 3. A bent portion of the suctioning pipe 6 is so determined that an axis of a rotary main shaft of a water turbine passes an outside of a flow passage sectional area in the case that the suctioning pipe 6 is cut by a horizontal surface including the lower reference point 9.

摘要： PROBLEM TO BE SOLVED: To solve the problem that a component cost is not only increased but also the influence of an input of an active change on an AC system is caused. SOLUTION: A single operation detector 8 of a distributed power source detects a single operation of the distributed power source when the AC system is power interrupted during interconnecting operation of the distributed power source and the AC system which outputs a power from the distributed power source 2 to the AC system 3 through a three-phase AC power source 4. The single operation detector 8 includes a CPU 23 for controlling an inverter 13 so that a power is extracted from one phase (S-T phase) of three phases (R-S phase, S-T phase and R-T phase) of the three-phase AC power source, and a frequency change detector 22 for detecting a frequency change based on the reactive power change from the power inputted by the reactive power change. The CPU 23 judges whether this frequency change is a predetermined level or not when the frequency change is detected, and detects the single operating of the distributed power source 2 when the predetermined level or higher is judged.

摘要： PROBLEM TO BE SOLVED: To prevent leakage of compressed air into a draft tube by branching a drain tube which drains residual water inside a cover to a draft tube, opening the branched upper drain tube to a portion upper than the pressed down water level in the draft tube pipe, and opening the lower drain tube to a portion lower than the pressed down water level. SOLUTION: A drain tube 11 arranged on a lower cover 4 is opened into a draft tube 5. The drain tube 11 is branched midway thereof. The branched pipe, that is upper drain tube 13 is opened to a portion upper than an initially set water level (a). A lower drain tube 14 is opened to the portion lower than the initially set water level (a). Compressed air, mixed into the drain tube 11, flows through the upper drain tube 13. Drain water, mainly including water with large specific gravity flows through the lower drain tube 14. An amount of air to be discharged into lower water is remarkably reduced. It is thus possible to prevent leakage of the compressed air into the draft tube 5.
