1.将弧光接地过电压限制在电网安全运行的范围之内,同时转移故障点,弥补了消弧线圈限制弧光接地过电压的不足,提高了电网的供电可靠性;
1. Limit the arc grounding overvoltage to the safe operation range of the power grid, and transfer the fault point at the same time, which makes up for the lack of arc suppression coil to limit the arc grounding overvoltage and improves the power supply reliability of the power grid;
2.限制过电压的机理与电网对地电容电流的大小无关,保护性能不随电网运行方式的改变而变化;
2. The mechanism of limiting over-voltage has nothing to do with the capacitance current of the power grid to the ground, and the protection performance does not change with the change of the operation mode of the power grid;
3.装置的结构简单,动作可靠,体积小,安装、检修方便适用于各种电力系统的运行;
3. The device is simple in structure, reliable in operation, small in volume, convenient in installation and maintenance, and suitable for the operation of various power systems;
4.装置具有较高的性价比,可取代消弧线圈、接地变压器及其控制屏,对于新建工程还可省掉PT柜。
4. The device has high cost performance, which can replace arc suppression coil, grounding transformer and its control panel. For the new project, Pt cabinet can also be omitted.
5.柜型可根据用户需求定做，满足用户并柜需求。
5. The cabinet type can be customized according to the user's needs to meet the needs of users' parallel cabinets.
