| 消弧消谐柜作用 Function of arc suppression and harmonic elimination cabinet 1.可在2个周波内熄灭弧光,有效地消除弧光接地过电压，从而可避免弧光接地引起的各种绝缘事故。 1. The arc light can be extinguished within 2 cycles, and the arc grounding overvoltage can be effectively eliminated, so as to avoid various insulation accidents caused by arc grounding. 2.由于各类相对地及相对相之间的操作过电压均被限制到较低的水平，这就大大降低了激发铁磁谐振的可能性。 2. As the switching overvoltage between phase to ground and between phases are limited to a lower level, the possibility of excitation of ferroresonance is greatly reduced. 3.微机消弧消谐装置与选线装置配合,选线效果理想。 3. The microcomputer arc suppression and harmonic elimination device and the line selection device cooperate, the line selection effect is ideal. 4.由微机消弧消谐装置的工作原理可知，其限制过电压的机理与电网对地电容电流大小无关，因而其保护性能不随电网运行方式的变化而改。 Therefore, the operation principle of the non harmonic protection is independent of the operation mode of the power grid. 5.微机消弧消谐装置可取代单独的PT柜。 5. Microcomputer based arc suppression and harmonic elimination device can replace separate Pt cabinet. 6.微机消弧消谐装置单独装柜，结构简单，安装方便，占地面积小，既适用于新建变电站，也适用于老站的改造。 6. The microcomputer arc suppression and harmonic suppression device is installed in a separate cabinet, which has the advantages of simple structure, convenient installation and small occupied area. It is not only suitable for the new substation, but also suitable for the transformation of the old station. |
