    • PURPOSE:To enable to simultaneously control a plurality of controllers inexpensively by dividing and storing a control command into control contents and control prescribed time, and outputting a control command when a time signal and the prescribed time coincide by a converter. CONSTITUTION:The control contents of a control command and a control prescribed time are respectively stored in a control contents memory 101 and a control prescribed time memory 102. These stored contents are transmitted through a transmitter 131 to an opponent converter. The numerals of a time unit 110 and the memory 102 are compared by a coincidence detector 103. When a coincidence is detected by this comparison, the gate of a control output circuit 104 is opened, and the content of the memory 101 is inputted to a controller 8. Even in the opponent converter, the contents of the memory are similarly inputted to the controller.

    • PURPOSE:To enhance the reliability of an AC/DC converter by multiplexing circuits which generate firing signals. CONSTITUTION:The DC current of a converter 2 is detected by a current transformer 3, and the output is inputted to control circuits 8-1-8-3. The outputs of the control circuits 8-1-8-3 are inputted to ring counters 9-1-9-3, thereby generating firing signals Ua-Za, Ub-Zb, Uc-Zc of 120 deg. in width. These firing signals are inputted to a multiplexing circuit 10 which has AND gates 11-1-11-3 and an OR gate, and the output is applied as a firing signal to the thyristor 2-1 of the converter 2 through pulse width converters 31-1-13-4 and a multiplexing circuit 14. The firing signal is applied to the other thyristor of the converter 2 in the similar constitution.

    • PURPOSE:To generate an optimum AC voltage in any event of operation by allowing a tap changer controller to control a setting input to a voltage adjusting relay during bipolar operation and unipolar operation. CONSTITUTION:The DC voltage of a power inverter side is controlled to a constant voltage under constant-voltage control, so the bipolar operation is changed into unipolar operation, the DC voltage of a power rectifier side should be raised by a voltage drop across the resistance Rn of a neutral conductor 17 by a current ID flowing through the conductor 17. A voltage regulator 19 controls a tap changer 3 so that actual AC voltage of a PT18 has the setting value Vref22. When the unipolar operation is detected from a voltage or current, a contact 21 is closed to adds a value proportional to preset ID.Rn to the voltage setting value Vref22 by an adder 20, boosting the AC voltage of the tap changer 3. Consequently, an optimum voltage is generated in any state.
    • 目的:通过允许分接开关控制器在双极操作和单极操作期间控制电压调节继电器的设置输入,在任何情况下产生最佳交流电压。 构成:电力变换器侧的直流电压在恒定电压控制下被控制为恒定电压,双极性工作变为单极性工作,电源整流器侧的直流电压应通过电阻上的电压降升高 通过流过导体17的电流ID的中性导体17的Rn。电压调节器19控制分接开关3,使得PT18的实际AC电压具有设定值Vref22。 当从电压或电流检测到单极性操作时,触点21闭合,通过加法器20将与预置ID.Rn成比例的值与电压设定值Vref22相加,从而提高分接开关3的AC电压。因此, 在任何状态下产生最佳电压。
