    • An electrical storage system includes: an electrical storage device (10) including serially connected electrical storage blocks; a relay (SMR-B, SMR-G) switching a connection state between the electrical storage device and a load; a controller (30, 34) controlling the relay; and a current interruption circuit (60) interrupting energization of the electrical storage device. The current interruption circuit (60) includes an alarm circuit (63) outputting an alarm signal indicating that any one electrical storage block is overcharged or overdischarged by comparing a voltage value of each electrical storage block with a threshold; a latch circuit (64) retaining the alarm signal; and a transistor (68) causing the relay to switch from an on state to an off state upon reception of a latch circuit output signal. The controller determines an energization state of the electrical storage device after executing control for causing the alarm circuit to output the alarm signal by changing the voltage value or the threshold.
    • 电气存储系统包括:电气存储装置(10),包括串联连接的电存储块; 继电器(SMR-B,SMR-G)切换蓄电装置和负载之间的连接状态; 控制所述继电器的控制器(30,34); 以及中断电气存储装置的通电的电流中断电路(60)。 电流中断电路(60)包括:通过将每个电存储块的电压值与阈值进行比较来输出指示任何一个电存储块被过充电或过放电的报警信号(63); 保持警报信号的锁存电路(64); 以及晶体管(68),其在接收到锁存电路输出信号时使得继电器从接通状态切换到断开状态。 控制器在执行使报警电路通过改变电压值或阈值来输出报警信号的控制之后,确定蓄电装置的通电状态。

    • A polarization independent optical isolator includes: a first birefringent plate that divides the receiver light from the optical transmission path into normal light and abnormal light to output the normal light and the abnormal light; a second birefringent plate that combines the normal light and the abnormal light to output the combined light to the light receiving element; an optical rotation unit that is disposed between the first birefringent plate and the second birefringent plate, rotates the polarization direction of the normal light and the abnormal light which are outputted from the first birefringent plate by substantially 90° and outputs the rotated light, and outputs the reflected light of the receiver light in a state where the polarization direction of the reflected light is not rotated; and a polarizing element that is disposed between the optical rotation unit and the second birefringent plate, allows one of the normal light and the abnormal light which are inputted from the optical rotation unit to pass therethrough and to be inputted to the second birefringent plate, and outputs the transmitter light inputted from the light emitting element to the optical rotation unit.
    • 偏振无关光隔离器包括:第一双折射板,其将来自光传输路径的接收器光分成正常光和异常光,以输出正常光和异常光; 第二双折射板,其组合正常光和异常光以将组合的光输出到光接收元件; 设置在第一双折射板和第二双折射板之间的光学旋转单元将从第一双折射板输出的正常光和异常光的偏振方向旋转约90°并输出旋转的光,并输出 在反射光的偏振方向不旋转的状态下的接收光的反射光; 以及设置在所述光学旋转单元和所述第二双折射板之间的偏振元件,允许从所述光学旋转单元输入的正常光和异常光中的一个通过,并输入到所述第二双折射板,并且 将从发光元件输入的发射光输出到旋转单元。
