Zusammenfassung: | The utility model discloses an electrical topology identification device for a low-voltage transformer area, and relates to an electrical topology identification device. At present, the transformer area identification principle usually adopts a voltage zero crossing point signal modulation mode of short-circuiting a phase line and a neutral line for a short time, and the scheme has the risk of long-time short circuit of the phase line and the neutral line. The device comprises a detection terminal host arranged at the head end line side of a distribution transformer, a line detection terminalslave arranged at a branch point or a meter box side, and a reactive pulse generation circuit connected with the line detection terminal slave and used for generating reactive pulses. Wherein the detection terminal host is wirelessly connected with the line detection terminal slaves, and the line detection terminal slaves are in communication connection with the corresponding concentrators. According to the technical sche |
