Title: Steam generator plant
Inventor: SANO KENJI
IPC: F22B1/06
Filed: 1987-09-14
Abstract: PURPOSE:To remove decay heat by detecting the pressure difference between the inlet and outlet of a recirculation flow passage valve, then by opening a spray supply valve to assure water in a steam separator when the detection signal attains a set differential pressure and by opening the recirculation flow passage valve when the water level in the separator attains a set water level. CONSTITUTION:The steam from a steam generator 1 after tripping of a nuclear reactor flows through a bypass valve 18 and a feed water heater 9 to a condenser 6 by bypassing a turbine 5. Since the flow rate of the feed water decreases, the differential pressure across the recirculation flow passage valve 14 increases from the negative toward the positive pressure. The differential pressure signal by a differential pressure detector 30 is inputted to a control circuit 31 and is compared with the set differential pressure. The spray supply valve 13 is opened when the differential pressure signal exceeds the set differential pressure. The feed water is then sprayed through a spray supply pipe 23 into the steam separator 4 by a nozzle 4 and is stored in the separator 4. The water level in the separator 3 is monitored by a water level gage 35. The valve 14 is opened by ANDing with the the open signal of the valve 13 when the monitored water level exceeds the set water level. The entire part of the system is thus maintained at the saturation temp. of water.

IPC: B60L7/04
Filed: 1994-08-30
Abstract: PURPOSE: To perform stable braking by starting plugging when a revolution speed is not less than a predetermined value after dynamic braking starts and predetermined time elapses. CONSTITUTION: A motor control device 10 is provided with a microcomputer 20 for controlling a motor 12 through a driving circuit 18 on the basis of the target signal SA of the revolution speed of the motor 12 by stepping an accelerator 14 and an actual revolution speed signal SR outputted by the revolution speed sensor 16 of the motor 12. The microcomputer 20 usually controls the motor 12 through the driving circuit 18 so that the signal SA accords with the signal SR, but when the acceleration signal SA is a zero, namely, a stop signal is outputted, the dynamic braking relative to the motor 12 is started.  When the rotational signal SR after predetermined time elapses is not more than a reference value Rt, deceleration is sufficient, so that the dynamic braking is continued, but when it is not less than the reference value Rt, deceleration is insufficient, so that plugging is started. Thereby, stable braking can be performed.
