| 消谐装置的可选功能 Optional function of antiharmonic device 本装置可按用户要求配置自动选线功能。 This device can configure automatic selection function according to user's requirement. 本公司研制的小电流选线装置，在金属接地时主要依据线路零序电流的幅值选线，弧光接地时主要依 The small current selection device developed by our company is mainly based on the amplitude of the zero sequence current of the line, which is mainly dependent on the frame 据装置动作前后线路零序电流的突变量进行选线。克服了常规的选线装置选线速度慢和弧光接地时选 According to the variation of the zero sequence current of the device before and after the motion, the line is selected. The selection of the speed of the selected line and the grounding of arc light is overcome 线准确率低的问题。 Low accuracy problem. 本装置可按用户要求配置消(除)谐(振)功能。 The device can be used to configure elimination (except) harmonic (vibration) function. 本装置可配置本公司研制的专用不饱和电压互感器，不仅从根本上破坏了铁磁谐振的条件，同时避免 This device can be equipped with the special unsaturated voltage transformer which is developed by our company, which not only destroys the condition of ferromagnetic resonance, but also avoids it 了因过电压引起的“烧PT”和“爆保险”的事故； The "burn PT" and "explosion insurance" accident caused by overvoltage; |
