Title: Method and apparatus for measuring ac magnetic characteristic
Inventor: MATSUMOTO YUJI
IPC: G01R33/12
Filed: 1988-03-16
Abstract: PURPOSE:To enable the measurement of AC magnetic characteristics directly utilizable for designing of an actual saturable reactor by constituting the above method and device in such a manner that the magnetic flux change speeds of a gate period and set period are specified and measured. CONSTITUTION:The AC magnetic characteristics of a magnetic core which makes a minor loop operation including the saturation region represented by the saturable magnetic core of a magnetic amplifier are measured. This measurement circuit is constituted of a gate circuit consisting of a power supply 21, a main switch 18, etc., and a control circuit consisting of a power supply and a main switch 19. The winding end voltage of a sample 2 and the excitation current measured by a current detector are subjected to A/D conversion then to arithmetic processing by which the calculation of a magnetic core loss, etc., is executed. Although the magnetic core loss varies with the magnetic flux change speed, said speed varies in the gate period and the reset period in case of the magnetic amplifier and the respective independent determinations of said speeds are necessitated. The magnetic flux change speed of the gate time is, therefore, specified by setting the voltage of the power supply 21 and a variable resistor 20 by the prescribed equation. The magnetic flux change speed of the reset period is specified by setting the control voltage and the reset period by the prescribed equation.

Abstract: PURPOSE:To efficiently raise the temp. of brine in a heat transfer pipe at a higher temp. side, by providing the heat absorbing part of a heat pipe at a higher temp. part at the side of a brine heater line and the heat discharging part of said heat pipe in a water chamber for recovering heat. CONSTITUTION:During ordinary full-load operation, equipment is driven while closing a control valve 23 provided in the middle of a heat pipe 22 to hold the function of the heat pipe 22 under an unacting condition. When the equipment comes under a partial load, the control valve 23 is released to operate the heat pipe 22. Hence, the drain heat of a brine heater 1 is transferred to brine inside a heat transfer pipe 26 at a circulating stage 21 by the action of the heat pipe 22 to raise the temp. of said brine, and all flash chambers are effectively driven to inhibit the deterioration of the efficiency of desalination. In this equipment, the heating temp. of brine in the heat transfer pipe at the circulating stage is controlled on the basis of the degree of a partial load, so that the efficiency of desalination can be maintained at a high value in response to various partial loads.

Title: Overvoltage suppressor
Inventor: ARAI JUNICHI
IPC: H02H7/045
Filed: 1990-03-14
Abstract: PURPOSE:To suppress overvoltage of a system of a case by generating a closing command to a breaker to connect an arrester to the system when the overvoltage due to an exciting rush current is generated. CONSTITUTION:When a transformer is energized, a closing command signal 4 is inputted to an OR circuit 6, from which the command is applied to a breaker 1 to connect an arrester 2 to an AC bus 3. An exciting rush current flows due to the energization of the transformer, but an overvoltage is suppressed by an operating voltage to be determined according to the characteristics of the arrester 2. If a system accident occurs, a system voltage is once lowered, and hence an insufficient voltage relay 5 is operated. Then, since the breaker 1 is closed, the same operation as that at the time of energization of the transformer occurs for the overvoltage generated by the energization of the transformer after the accident is removed. Accordingly, an overvoltage of the system due to the rush current of the transformer can be suppressed.
