Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of a resonant overvoltage by computing the conditions of a large resonant overvoltage that rarely appears, using a program for computing equivalent circuit constants or using actual measurement, and adjusting an electrostatic shield on a transformer winding so as not to satisfy the conditions. SOLUTION: In a method of preventing a duplicate resonance, a program for computing an equivalent circuit constant of a transformer is used for computing an inductance L1, an inductance L2, a capacitance C1, and a capacitance C2 of a main winding 1 and a tap wiring 2, a capacitance between the main winding 1 and the tap winding 2, and proportionality constants (a) and (b) of the inductance (C1=aC2, L1=bL2). And then, if these values of windings placed in series are close to each other, an electrostatic shield is provided on a winding disposed on a high potential side. When the winding already has an electrostatic shield, the effect is adjusted. In order to change the construction so as to have a larger effect, element wires are combined with each other so as to increase a potential difference between the adjacent element wires.

Title: Current command circuit of power conversion device
Inventor: TANAKA MASAO
IPC: H02M7/21
Filed: 1990-12-25
Abstract: PURPOSE:To prevent the output current of a power conversion device from fluctuating by preventing an AC current command value of the power conversion device which converts an AC to a DC from changing in correspondence to the fluctuation of an AC supply voltage. CONSTITUTION:When converting a DC current command value to an AC current command value using an AC supply voltage, the DC current command value is preliminarily divided by the DC voltage proportioned to an AC supply voltage and then it is converted to an AC current command value using this AC supply voltage. By this method, even if the AC supply voltage fluctuates, the effect of this fluctuation is offset and thereby the AC current command value can be stabilized. Or, with the AC supply voltage being held constant by a voltage stabilizing device, a stable AC current command value can be generated using this fixed AC supply voltage and therefore the output current of a power conversion device is prevented from fluctuating.

CONSTITUTION:Drum shear blades 4a and 4b are lapped, and in the instant that a strip 1 is cut, a hydraulic pressure is applied to a tilting cylinder 8 at the lower dead center, so as to incline a plane including the shaft cores of the upper and the lower drum bearings 6a and 6b at the angle theta to the advancing direction of the strip 1. The shaft 6a is moved the amount  x=Dsin theta/2 in the strip advancing direction, and the shaft 6b is moved the same amount in the reverse direction. (In this formula, D is the diameter of the drum.) To the peripheral speed V of the drum, the edge speed of the upper blade 4a is made as the speed v+DELTAv adding the moving speed DELTAv in the inclination, while the edge speed of the lower blade 4b is made as v-DELTAv. Consequently, a bending of the tip of the blade can be prevented.
