The quality of electric power caused by frequency fluctuation and voltage rise will be degraded because of the lightning surge and the mass introduction of distributed power. Thus, it is necessary to improve the performance of gas circuit breaker in order to maintain the stable supply of electric power. It has been reported that the arc conductance is calculated as the index of the current interruption in numerical analysis. However, few report have the measured value in the current interruption. This is because that the current interruption is the steep phenomenon of micro seconds range. Thus, it is necessary to establish the time‐high precision and noncontact measurement method. In this paper, the arc temperature is measured near current zero using the microsecond spectroscopic measurement. As a result, the microsecond spectroscopic measurement which combines the conventional spectroscope and the high speed video camera is 200 times faster than the measurement of conventional spectroscope. For this reason, the microsecond spectroscopic measurement is possible with the high speed video camera. Therefore, it is possible to measure the arc temperature with decreasing the current using the microsecond spectroscope.

微秒光谱测量法测量电弧温度

由于雷电浪涌和大量引入的分布式电源，由频率波动和电压上升引起的电源质量将下降。因此，有必要提高气体断路器的性能，以维持稳定的电力供应。据报道，在数值分析中，电弧电导被计算为电流中断的指标。但是，很少有报告具有当前中断中的测量值。这是因为电流中断是微秒级的陡峭现象。因此，有必要建立时间高精度和非接触式测量方法。在本文中，使用微秒分光光度法在零电流附近测量了电弧温度。结果是，将传统光谱仪和高速摄像机相结合的微秒光谱测量比传统光谱仪的测量快200倍。因此，使用高速摄像机可以进行微秒级光谱测量。因此，可以使用微秒光谱仪在减小电流的情况下测量电弧温度。
