浅谈并网光伏逆变器的漏电流保护

Discussion on Leakage Current Protection of Grid Connected Solar Inverter

在光伏逆变器应用场景中为降低风险,从而达到对漏电的有效防护。然而在实际应用过程中,由于各厂家设备的设计方案不一样,需充分考虑漏电采样的计算机制和其它器件对系统漏电采样的带来的影响,最大程度的反馈真实漏电,正确使用交直流检测传感器是很有必要的。

In the photovoltaic inverter application scenario to reduce the risk,So as to achieve effective protection of leakage current.however,in the actualapplication process,due to the different design schemes of the equipment ofvarious manufacturers,it is necessary to fully consider the calculationmechanism of leakage current sampling and the impact of other devices on theSystem leakage current sampling,and to maximize the feedback of the realLeakage current,the correct use of AC-DC detection sensors is necessary.
