摘要： PURPOSE:To reduce the load of a computer and to rapidly output a diagnostic result by providing a plurality of detectors or detection items and always monitoring the interior of machinery at a usual time by one of them and performing precise diagnosis by the other when abnormality is detected. CONSTITUTION:The detectors 10, 20, 30 connected to analysers 40, 50, 60 are provided and the detector 10 is always selected as a monitoring one. For example, if the detector is a partial discharge pulse current detector, a detection level, a phase and a frequency band are provided as detection items. The detector 10 monitors the interior of machinery on the basis of the detection items and, when abnormality is detected, the interior of the machinery is precisely diagnosed by the other detectors 20, 30 using the detection items thereof. Herein, according to a purpose and necessity, the detector 20 or 30 can be also always selected as the monitoring one. Since the detection items of the detectors are selected to perform monitoring as mentioned above, load such that a computer 70 always processes a signal is reduced, and the rapid judge of abnormality and a rapid order can be issued.

CONSTITUTION:A gas insulating apparatus 1 is provided with a discharge detector 10 and an acoustic detector 11, and its output is inputted to a signal analyzing part 12. An output of the analyzing part 12 is inputted to a diagnostic part consisting of a memory 13a for storing temporarily data, a standard pattern store part 13b for storing standard date, and an abnormality deciding part 13c for comparing the patterns of the memory 13a and the pattern store part 13b and deciding the abnormality. Also, said apparatus is constituted so that an alarm of a trip signal is outputted by a command part 15 by a result of said diagnosis, and the result is outputted by a display part 16. In such a way, the generation of corona discharge and a size of a projection of the generation cause can be known, and the existence of a free grain can also be detected.

摘要： PROBLEM TO BE SOLVED: To increase the output of a rotating electric machine by reducing reactance induced by the stator winding thereof. SOLUTION: In a stator core, a plurality of magnetic poles are formed so that stator claw magnetic poles alternately extend from both sides of an axial direction in a position opposite to a rotor, and the gap distance between the front end portions of the stator claw magnetic poles and the stator outer circumference is increased, the reactance induced by the stator winding is reduced. The magnetic reluctance manifesting between the front end portions of the stator claw poles and an enclosing member that holds the stator core opposite the centers of the claw poles along the circumferential direction, is made larger than the magnetic reluctance manifesting between the front portions and the stator core enclosing member opposite the front end portions.

摘要： PROBLEM TO BE SOLVED: To easily wind even stator windings having a plurality of winding groups, or to change the conduction states of winding groups according to use. SOLUTION: The winding groups 19Ua, 19Va and 19Wa at the first three-phase winding 1911 and the winding groups 19Ub, 19Vb and 19Wb at the second three-phase winding 1912 are made different from each other, so that the windings for use by a switch 21 may change. By this, the windings can be changed according to use, and even the stator windings 19 having the plurality of winding groups can be easily wound since a stator core 18 is of a claw pole type.

摘要： PROBLEM TO BE SOLVED: To enhance the space factor of a stator coil in the slot of the stator and to form a magnetic path surely around the rotor and the stator coil.
SOLUTION: The core comprises an annular outer core, and an inner core where a plurality of slots for winding the stator coil periodically open to the outer circumferential side, and teeth provided between the slots of the inner core are coupled on the inner circumferential side by means of a nonmagnetic member such as resin. Since the stator coil is not inserted from the inner circumferential side of each teeth of narrow width but can be inserted from the outer circumferential side, space factor of the stator coil in the slot of the stator can be enhanced. Furthermore, since a magnetic path is not formed easily on the inner circumferential side of each teeth because of a nonmagnetic member such as resin, the magnetic path can be formed surely from the rotor to the outer core.

摘要翻译：要解决的问题：为了提高定子线圈的定子线圈的空间因子，并且可靠地形成绕转子和定子线圈的磁路。解决方案：芯包括环形外芯和内芯，其中多个用于将定子线圈卷绕到外周侧的槽，并且设置在内芯的槽之间的齿连接在内芯上通过诸如树脂之类的非磁性部件的周向侧。由于定子线圈不从每个宽度窄的齿的内周侧插入，而是可以从外周侧插入，因此可以提高定子线圈在定子的槽中的空间因数。此外，由于由于诸如树脂的非磁性部件而在每个齿的内周侧上不容易形成磁路，所以可以从转子到外芯可靠地形成磁路。版权所有（C）2008，JPO＆INPIT
