Zusammenfassung: | The invention discloses intelligent phase selection controller equipment which comprises a programmable logic device, an IGBT module, a merging unit CPU module, a voltage/current transformer, a first transceiver, an intelligent terminal CPU module, a switch-in/out module and a second transceiver. The merging unit CPU module and the IGBT module are connected with the programmable logic device. The merging unit CPU module collects voltage/current analog quantity of the voltage/current transformer. The intelligent terminal CPU module collects switch input/output quantity information. A transmit-receive GOOSE is in communication with spacer layer equipment. The merging unit CPU module and the programmable logic device carry out operation processing through a CPU, voltage-current zero crossing point time is predicted, and IGBT module action is controlled. An IGBT is used for controlling a breaker to achieve tripping and closing at a voltage-current zero crossing position, inrush current surging or transient overvoltage generated during tripping and closing of the breaker is reduced, and the using rate of electric equipment is improved. |
