Title: Shaft voltage reducing device for synchronous machine
Inventor: MORIYASU MASAJI
IPC: H02K11/00
Filed: 1989-05-25
Abstract: PURPOSE:To reduce a shaft voltage by compensating a common mode voltage generated between the shaft of a synchronous machine to be energized by a thyristor exciter and the ground. CONSTITUTION:A shaft voltage compensator 6 for generating a compensating voltage having the same amplitude as that of a common mode voltage Vc and a reverse phase is provided between a neutral point formed by providing a capacitor 5 at an AC side lead and the ground. The compensating voltage generated from the compensator 6 is applied to the neutral point of an exciting transformer 4 to compensate the voltage Vc. That is, since the compensating voltage to be applied to the AC side neutral point of a thyristor exciter 3 has a reverse phase to that of the voltage Vc, an average value of a voltage between the neutral point of a DC side voltage of the exciter and the ground, i.e., between an exciting winding 2 and the ground becomes zero. Thus, a shaft voltage generated due to the exciter can be eliminated. Accordingly, the electrolytic corrosion of the shaft of a synchronous machine can be prevented, and the wear of a shaft ground brush can be reduced remarkably.

Abstract: PURPOSE: To accomplish a rapid lowering of the car level by means of a hydropneumatic suspension apparatus permitting free selection of any car level according to level according to the road condition.  
     CONSTITUTION: Hydropneumatic suspension units 1 and 2 are arranged in such a manner that a cylinder 3 and a piston rod 5 thereof are connected respectively to the car body and a suspension member suspended on the corresponding wheel. The car level is lowered by discharging a working oil from the units 1 and 2 through a oiling port 10 thereof. In this apparatus, a solenoid valve 16 which is normally open is provided to the passage 15 through which the cylinder 3 and a gas spring 9 are communicated to each other. The valve 16 is closed whenever the car is being lowered. With such an arrangement, while the working oil is discharged from the units 1 and 2, the working oil accumulated into the spring 9 can be kept in storage, thus saving so much the time required for oiling and oil discharging.
