Abstract
The invention provides a pulse type electricity acquiring method of a line fault indicator. An electricity acquiring capacitor is connected in series in a line, i.e. the electricity acquiring capacitor is connected in series between the phase end and the ground end of the line so that three equivalent series capacitors are respectively formed by the phase end and one end of the electricity acquiring capacitor, one end of the electricity acquiring capacitor and the other end of the electricity acquiring capacitor, and the other end of the electricity acquiring capacitor and the ground end, and thus voltage acquired by the electricity acquiring capacitor is not influenced by current and reliability of the line can be guaranteed. Meanwhile, a microcontroller is adopted to control pulse generation and then control an energy storage capacitor to charge a power supply so that reliability of the line is further enhanced. Monitoring of the circuit of the whole line is completed when the microcontroller samples and monitors voltage of the electricity acquiring capacitor so that the structure is simple and use is convenient. Meanwhile, an overvoltage protection unit and a current-limiting resistor are also arranged in the line so that protection for all parts and components of the line can be further enhanced.
