摘要（英）：

The invention discloses a single-phase phase-selection system. The single-phase phase-selection system is a JDSX type single-phase grounding phase-selection control unit; the single-phase phase-selection system comprises a DSP data processing and input signal acquisition board, a PC104 display and processing module, a power panel, a sensor plate, an MOSFET output plate and a charging plate; and the power panel is connected with the DSP data processing and input signal acquisition board and the charging plate, the charging plate is connected to the MOSFET output plate, and the DSP data processing and input signal acquisition board is connected with the sensor plate, the MOSFET output plate and the PC104 display and processing module respectivley. Through application of the single-phase phase-selection system of the invention, when a fault phase is grounded, the fault phase can be accurately and rapidly selected.
