摘要（英）：

The invention provides a primary protection circuit of a 10kV power frequency freewheeling test device. The primary protection circuit comprises an impact voltage side protector and a power frequency voltage side protector, wherein the impact voltage side protector is connected in series with a circuit at one side of an impact voltage generator and is used for protecting the impact voltage generator from being damaged by a power frequency voltage after lightning wave attenuation, and the power frequency voltage side protector is connected in parallel with a circuit at one side of a power frequency voltage source and is used for protecting the power frequency voltage source from being damaged by an impact overvoltage and an impact overcurrent when the impact voltage acts. The primary protection circuit is advantaged in that the impact voltage generator and a power frequency test transformer can be effectively protected, and reliability and stability are improved.
