摘要： The present application discloses a method and apparatus for detecting insulation impedance of a direct current side of a photovoltaic inverter. The photovoltaic inverter includes a direct current input terminal, a positive terminal of a direct current bus, a negative terminal of the direct current bus, a signal protective earthing, and a protective earthing. The direct current input terminal of the photovoltaic inverter is used to connect at least one string of photovoltaic panels. The method includes the following steps: sampling a voltage of the protective earthing and a voltage of the positive terminal of the direct current bus respectively; obtaining a first voltage difference between voltages of the protective earthing at different moments and a second voltage difference between voltages of the positive terminal of the direct current bus at different moments; and calculating the insulation impedance of the direct current side of the photovoltaic inverter based on the first voltage difference, the second voltage difference, a resistance of an equivalent resistor between each terminal of the photovoltaic inverter and the signal protective earthing, and resistances of equivalent resistors between the positive terminal and the negative terminal of the direct current bus and the protective earthing. According to the method, an impact of the resistance of the resistor between each terminal and the signal protective earthing is eliminated, so that detection accuracy is improved, and there is no need to add an additional device, costs are reduced.
