| description | The anti-resonance voltage transformer with the grounding compensation function based on the Y-type wiring comprises a PT primary winding, a PT secondary winding and an iron core, a neutral point of the PT primary winding is connected with a damping resistor in series and is grounded, a compensation reactor is connected between the neutral point of the PT primary winding and the damping resistor in series, and the compensation reactor is connected with the iron core in series. The two sides of the damping resistor are provided with a control switch assembly in parallel, wherein the control switch assembly can quickly short-circuit the damping resistor when the system has a single-phase earth fault. According to the utility model, a PT primary winding adopts Y-shaped wiring and is grounded through a compensation reactor and a damping resistor, and the damping resistor is automatically switched on or switched off under the control of a self-triggering bidirectional silicon controlled rectifier switch; when the |
