不稳定电弧
不稳定电弧
由于故障电流小、电弧不稳定等原因,小电流接地系统单相故障选线问题始终没有得到彻底解决。
The characteristics of arc furnace are low voltage, big current and nonlinear load. Much negative sequence current is produced during running. As a result, the power net is unstable.电弧炉具有低电压、大电流而且负荷非线性的特点,在其运行过程中产生大量的负序电流,导致电网不稳定。
Apply high voltage pilot arc and high frequency stable arc with constant current properties, prevent influence from unstable voltage of power grid.采用高压维弧和弱高频稳弧,同时具有恒流特性,不受电网电压波动的影响。
