摘要： PROBLEM TO BE SOLVED: To provide a transformerless inverter 3 capable of suppressing fluctuation in a ground voltage to prevent mulfunction of a system protection device 2. SOLUTION: An intermediate connection point 10 of a filter capacitor 8 of a DC intermediate circuit of a transformerless inverter 3, which does not contain a transformer, is grounded between a converter 7 and a zero-phase current transformer 5. The zero-phase current that flows an earth line 11 is detected with a current transformer 12 that penetrates the earth line 11 (1), or a differential current that flows the positive/negative connection line of the DC intermediate circuit is detected with a current transformer 15 or a reactor 17 (2). The output is made to penetrate the zero-phase current transformer 5, in the direction opposite to that of a system 1, through a band pass filter 13 whose impedance is low to a third harmonics 3f 0 frequency of the voltage of the three-phase AC system 1. The transformerless inverter detects a zero-phase current that flows due to grounding, which is offset with the signal detected by the zero-phase current transformer 5, to prevent mulfunction of the system protection device 2 for suppressing fluctuation in a ground voltage.

摘要： PROBLEM TO BE SOLVED: To provide a resin mold winding body formed by integrally resin- molding windings such as a primary coil and a secondary coil, etc., a wiring and an iron core without causing a harmful crack that can cause dielectric breakdown. SOLUTION: Thermal stress generated when the windings such as the primary coil and the secondary coil, the wiring and the iron core are integrally resin- molded is generated when the iron core does not shrink and the resin starts shrinking. Then, by forming a gap of resin around the iron core, the thermal stress is reduced. By providing a domy separation promoting tube extending into the resin from the periphery of the iron core, separation is induced, and the thermal stress is absorbed by this separated part.

摘要： PROBLEM TO BE SOLVED: To easily nondestructively judge whether or not an electric rotating machine can be driven by means of an inverter. SOLUTION: The surface propagating speed in the electric rotating machine and the voltage increasing rate at the connection between a cable and the machine are measured by using a surge power source and the voltage born by interlayer insulation is determined based on the measured surge propagation speed and voltage increasing rate and the duration of wavefront of a specimen inverter. Then the determined voltage born by interlayer insulation is compared with the partial discharge characteristic and voltage-applied life-time characteristic of the electric rotating machine. When the voltage born by interlayer insulation is lower than the partially discharged voltage of interlayer insulation or the voltage-applied life-time at the voltage born by interlayer insulation is equal to or longer than the remaining life-time of the whole electric rotating machine, it is judged that the machine can be driven by means of the specimen inverter.
