| description | The invention discloses an iron core grounding current suppression device for a power transformer, and belongs to the technical field of circuits. According to the iron core grounding current suppression device, a current sensor receives a real-time large current signal and converts the real-time large current signal into a real-time small current signal; the adjusting circuit is connected with the current sensor to obtain a real-time small current signal and convert the real-time small current signal into original current data; the DSP controller is connected with the adjusting circuit, obtains the original current data and judges that the original current data is larger than a limit threshold value so as to send a trigger signal; the driving circuit is connected with the DSP controller and is used for acquiring and transmitting a trigger signal; the rectifying circuit is connected with the driving circuit, converts the obtained trigger signal into a suppression current, and converts the suppression current |
