    • Primary and secondary windings of each transformer in a three-phase system each form a pair of independent windings, the first winding of each of the primary and secondary pairs formed on the iron core of one of the transformers and the second winding of each of the primary and secondary pairs formed on the iron core of the transformer adjacent thereto are connected in series to each other. These serially connected windings are regarded as one phase winding respectively, and they are connected to each other in either a delta connection or a Y connection. A variation in the voltage phase caused by a change in the load current of one of the system outputs has an influence not only on the phase of the voltage at that output but also on the phase of the voltages on the outputs adjacent thereto and consequently enables the deviation in the phase difference between the output phase voltages due to loss of balance of the load to be decreased to about one half. When the leg parts of two adjacent iron cores are juxtaposed and a common winding is formed on the juxtaposed leg parts so that one winding may function equivalently as two windings connected in series, the number of windings required in all is one half of the number of windings required where the windings are formed independently on the leg parts of the cores.
    • 三相系统中的每个变压器的初级和次级绕组各自形成一对独立的绕组,其中一个变压器的铁芯上形成的每个初级和次级对的第一绕组和每个变压器的每一个的第二绕组 形成在与其相邻的变压器的铁芯上的初级和次级对彼此串联连接。 这些串联的绕组分别被认为是一个相绕组,并且它们以三角形连接或Y连接彼此连接。 由系统输出之一的负载电流变化引起的电压相位的变化不仅对该输出端的电压的相位产生影响,而且也影响与其相邻的输出上的电压的相位,并因此使能 由于负载平衡的损失导致的输出相电压之间的相位差的偏差减小到约一半。 当两个相邻的铁芯的腿部并列并且在并置的腿部上形成公共绕组时,使得一个绕组可以等效地作为串联连接的两个绕组起作用,所有所需的绕组数量为 绕组在芯的腿部部分上独立形成所需的绕组。

    • PROBLEM TO BE SOLVED: To provide a piston monitoring device for a gas holder to accurately monitor by a simple structure the inclination level of a piston of a gas holder and the level of grease and seal oil for a seal part of the piston. SOLUTION: This piston monitoring device comprises a plurality of laser range finders 6 disposed along the circumferential direction of an inner surface of the gas holder 1 on a ceiling part of the gas holder 1. By causing laser light from the range finders 6 to reflect toward the range finders 6 severally corresponding to reflectors 7 provided on outer circumferential parts of the piston 2, distances from the respective range finders 6 to corresponding reflectors 7 are measured while the inclination level of the piston 2 is operated by an arithmetic unit from differences in distances measured by the respective range finders 6. An alarm signal is issued when the operated inclination level of the piston is equal to or more than a prescribed inclination level. COPYRIGHT: (C)2005,JPO&NCIPI
