Title: Power converter
Inventor: IGAWA HIDEKAZU
IPC: H02M7/155
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To provide a power converter which materializes fault detection and protection of each constituent element within a switch unit. SOLUTION: In a normal operation, when GTOs 6 and 7 are turned off, a current which was flowing to the GTOs is shifted to diodes 9 and 10, and charges a capacitor 11. At this time, the increase in the charge voltage can be known by a voltage detector 18. Next, when the GTOs are turned off, the capacitor 11 which was being charged is discharged, and the reduction in the charge voltage can be known. At this time, if a sufficient discharge is performed, the charge voltage becomes roughly zero. In the case of turning off the GTOs again, the voltage of the capacitor 11 is measured with the voltage detector 18, and if the charge voltage is left, it is known that the on-period of the GTOs is short and that the capacitor 11 is not discharged sufficiently. In this way, a series of normal operation of the switch unit 12 can be known by the condition of the voltage of the capacitor 11.

Title: Steam plant
Inventor: URABE TAKAMASA
IPC: F28D20/00
Filed: 1986-07-14
Abstract: PURPOSE:To save the steam extraction in a turbine by performing the heat- reserve of a heat-reserving medium by means of the heat source of bypass steam and excess steam at the time of plant starting and also providing a heat-reserving mechanism for releasing heat if necessary and heating supplied water. CONSTITUTION:As SP valve 14 is closed so as to supply generated steam to tubes 7 inside a heat exchanger 6, lithium bromide LiBr solution with low concentration, which fills the inside of the heat exchanger 6 is heated and water is only evaporated in the solution so as to take away evaporative latent heat from the tubes 7. In this case, bypass steam is condensed inside the tubes 7 so that the condensed heat is taken away. The steam generated inside the heat exchanger 6 passes through a communicating tube 9 and condensed in the cooling tube 9 inside the heat exchanger 6, and then the condensed heat is exhausted into cooling water. As a result, the concentration in the lithium bromide LiBr inside the heat exchanger 6 becomes higher by dewatering. That is, the heat of the steam can be replaced to the concentration difference energy of the lithium bromide LiBr. Therefore, the steam extraction in a turbine can be saved so that it is possible to improve the output of the turbine.
