Title: Single line-to-ground fault annihilating system
Inventor: KAI TAKAAKI
IPC: G05F1/70
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To annihilate fault current with accuracy by finding a supply current of a rector device required for annihilating the fault current from the zero-phase- sequence current of each feeder and zero-phase-sequence voltage, and controlling the thyristor firing angle of the reactor device according to the obtained supply current. SOLUTION: A thyristor-controlled variable reactor device 6 is installed, and the firing phase of the thyristors is controlled by a line-to-ground fault annihilator 7. Specifically, the line-to-ground fault annihilator 7 uses the zero- phase-sequence currents I01 -I0n of feeder 31 -3n and the zero-phase-sequence voltage V0 of a distribution substation as detection input, and provides the thyristors Th1, Th2 of the thyristor-controlled variable reactor device 6 with a phase control signal and thereby annihilates single line-to-ground fault current. Thereby, a fault current can be annihilated with accuracy without monitoring or grasping the ground capacitance capacity of all the feeders 31 -3n when a single line-to-ground fault occurs in the feeders 31 -3n .

Filed: 1980-04-17
Abstract: PURPOSE: To reduce the fluid resistance loss and facilitate the control of the flow rate by installing the cylindrical body having inner screwed part which is rotatable  freely and screwed with the outer end of a valve stem.  
     CONSTITUTION: When a cylindrical body 10 having inner screw part is turned, a valve stem 8 is guided in the guide groove 9 of a holding body 4 and is shifted in the vertical direction by the screw action between the inner screw and the top end of the valve stem. Therefore, the valve plug 7 of which valve stem 8 is fixed shifts in the vertical direction, and the gap between a valve seat 3 and the valve plug 7 is varied. Because the structure of the through-flowing part of the valve body is of straight cylinder type, and the valve seat 3, valve plug 7, and the valve stem 8 are arranged in series in this order, and each is set at the center of the opening diameter of the through-flow, inclination of flow or deflection phenomenon is not generated, and the most effective flow-through state can be obtained. Further, the valve plug operates perpendicularly to the valve seat, correct and fine control of flow rate is permitted.
