Multi-dimensional self-sensing intelligent column switch

The invention provides a multi-dimensional self-sensing intelligent pole-mounted switch. The pole-mounted switch structurally comprises a solid-sealed polar pole and a switch operation box, and the solid-sealed polar pole internally comprises a current transformer, a capacitance voltage division type voltage sensor and a capacitance electricity taking module; according to the technical scheme, the self-sensing pole-mounted circuit breaker has the functions of temperature and humidity measurement, sound partial discharge recognition, sound mechanical characteristic recognition, data communication and the like and can provide the operation state of a switch body to the outside. The partial discharge recognition scheme is a linear four-microphone array, recognition and positioning are carried out through sound, and the scheme is low in hardware cost, free of contact with strong current, high in safety and easy to popularize. According to the invention, a UHF passive wireless sensor is adopted for temperature mea
