Other AbstractThe invention relates to an intelligent grid disconnection/connection switch with a detection function, and an implementation method therefor. The switch comprises a DSP processor module, a power module, a clock module, a detection module, a relay control module, a communication module, and a sensor module, wherein the power module, the clock module, the detection module, the relay control module, the communication module and the sensor module are respectively connected with the DSP processor module. The relay control module is connected with a circuit breaker. The method comprises the following steps: enabling the DSP processor module to judge an AC voltage phase difference between a microgrid side and a large grid side according to the detected voltage and current data obtained by an AD sensor; enabling a three-phase circuit breaker to remain off through the relay control module during no connection; and controlling a relay to switch on the circuit breaker when a DSP processor obtains a grid connected signal of a microgrid central controller through a communication module and the AC voltage phase difference between the microgrid side and the large grid side is less than a set value &. According to the invention, a function of grid connected point detection, a function of automatic control and a function of network communication are integrated into one switch. The switch is high in universality, has a large number of functions, and is convenient to use.
