    • PURPOSE: A rotor bar malfunction diagnosis system of an induction motor is provided to precisely diagnose whether a rotor bar of the induction motor is out of action or not under the light load condition. CONSTITUTION: A rotor bar malfunction diagnosis system of an induction motor comprises a current detector(110), an operating unit(120), and a diagnosis processing unit(130). The operating unit inputs motor specification information including power frequency of the induction motor, the number of rotor slots, the number of polarities, rated service speed, and synchronous speed. The current detector detects a current passing through a power supplying line connected with the induction motor. The diagnosis processing unit diagnoses whether a rotor bar of the induction motor is out of action or not from the motor specification information.

    • PURPOSE: A stator coil fault diagnosis system of a three-phase induction motor is provided to enhance coil fault diagnosis precision. CONSTITUTION: A current detection unit detects a current passing through a power supply line connected with a three-phase induction motor. A diagnosis processing unit diagnoses whether a stator coil is out of action or not from a three-phase current signal detected in the current detection unit. A Park's vector calculating unit(130) divides a three-phase current into d-shaft current and a q-shaft current through dq conversion. A distortion rate calculating unit(140) calculates distortion rate according to a Park's vector trajectory pattern. The distortion rate is a ratio of the biggest amplitude and the smallest amplitude of the Park's vector trajectory pattern. A fault diagnosis unit(150) calculates an average value of a distortion rate value.
    • 目的:提供三相感应电机的定子线圈故障诊断系统,以提高线圈故障诊断精度。 构成:电流检测单元检测通过与三相感应电动机连接的电源线的电流。 诊断处理单元从当前检测单元中检测到的三相电流信号诊断定子线圈是否失灵。 公园矢量计算单元(130)通过dq转换将三相电流分为d轴电流和q轴电流。 失真率计算单元(140)根据Park的矢量轨迹模式计算失真率。 失真率是Park矢量轨迹模式的最大振幅和最小振幅的比值。 故障诊断单元(150)计算失真率值的平均值。

    • PURPOSE: A hydrogen generator is provided to efficiently control the generation speed of hydrogen gas based on the dissolution reaction of aluminum or hydrolysis using a simple unit. CONSTITUTION: Alkaline aqueous solution(10-a) is filled in a reaction chamber(10) in order to generate hydrogen gas. A cylinder(21) is arranged at the upper side of the reaction chamber, and the lower part of the cylinder is open. A bellows(23) is inserted into the cylinder, and the upper side of the bellows is upwardly moved when high pressure hydrogen gas is introduced into the inner side of the cylinder. A hydrogen generation reaction accelerating unit(40) is installed at an accelerating unit mounting frame(30). The accelerating unit is submerged in the alkaline aqueous solution. The upper side of the mounting frame is in connection with the upper side of the bellows, and the mounting frame vertically moves. A water storing container(50) is filled with water(50-a) and is installed at one side of the reaction chamber. The hydrogen gas is discharged to the outside through the water storing container.
