保定电气厂

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. can extinguish arc in 2 circumferential waves, effectively eliminate the overvoltage of arc grounding, so that all kinds of insulation accidents caused by arc grounding can be avoided.

2.微机消弧消谐装置可取代单独的PT柜。

The 2. microcomputer arc elimination device can replace the single PT cabinet.

3.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

The 3. microcomputer arc elimination device is simple in structure, convenient in installation and small in area. It is not only suitable for new substations, but also suitable for the reconstruction of old stations.

4 能将大气过电压和操作过电压限制到较低的电压水平，保证了电网及电气设备的绝缘安全，大大降低了激发铁磁谐振的可能性，使因过电压引起的连发事故大为减少。

4, it can limit the over voltage and operation overvoltage to low voltage level, ensure the insulation safety of power grid and electrical equipment, greatly reduce the possibility of excitation ferromagnetic resonance, and reduce the number of continuous accidents caused by overvoltage.

5 能够迅速准确查找单相接地故障线路，对防止事故的进一步扩大，减轻运行和维护人员的工作量有重要意义。

5 can quickly and accurately find the single-phase grounding fault line, to prevent the further expansion of the accident and reduce the workload of the operation and maintenance personnel is of great significance.
