Title: Equipment and method for controlling semiconductor switch of series capacitor
Inventor: KONISHI HIROO
IPC: H02J3/16
Filed: 1994-03-16
Abstract: PURPOSE:To suppress the abnormality of a power system when its series capacitor is connected or its axis torsion signal is generated or its synchronizing signal is eliminated due to a fault, by generating the ignition pulse of its thyristor through the output signal of its synchronizing signal generator which is synchronized with a virtual phase associated with the terminal voltage of its series capacitor. CONSTITUTION:The voltage of an AC power supply 1 is boosted by a transformer 3, and is transmitted to a load side AC power system 2 through two-circuit long-distance transmission lines 41, 42. With both the ends series capacitor devices 51-54 controlled by thyristor controllers 31-34 having identical configurations with each other are connected respectively. In the series capacitor device 52, a series capacitor 501, inverse-parallel thyristors 503, 504 and a series reactor 502 are provided respectively, and when a power transmission is started the capacitor 501 is bypassed by a transmission current through the ignitions of the thyristors 503, 504. The series capacitor device 52 is controlled by the thyristor controller 31 while the terminal voltage of the capacitor 501 and the current of the transmission line 42 are sensed respectively by a PT 505 and a CT 504. Thereby, even if the reference position of the control of the series capacitor is displaced by the starting and fault of the power transmission, the virtual phase for the control is outputted from the controller 31, and as a result, the abnormal phenomenon of the power system is suppressed.

Title: Method for preventing adhesion of zinc, lead to tube wall or the like
Inventor: ISHIWATARI NATSUO
IPC: F27B3/19
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To effectively prevent adhesion growth of zinc, lead by blowing cooling agent from a plurality of places along gas flowing direction in a method for preventing precipitation or deposition of zinc, lead vapors at a tube wall by blowing the agent into the tube for feeding gas generated from a smelting apparatus. SOLUTION: Cooling agent blowing nozzles 2, 3 are installed at upper and lower stages from upstream side along a gas flowing direction in a tube 1 of a gas flowing passage in a smelting furnace in the state that it is projected into a pipeline. In this case, a cooling and blowing direction from the nozzle 2 is brought into contact with a downstream side nozzle 3 and its vicinity or particularly with a tube wall. With such nozzles 2, 3, zinc, lead are condensed and solidified at the nozzle site and tended to be deposited, but cooling agent blowing from uppermost stream is stopped, combustible gas and oxygen- containing gas are blown instead of the agent from the agent inlet of the uppermost stream side to evaporate and vaporize adherent substance, or to melt and liquefy it, thereby vanishing deposit of the adherent substance.
