The invention discloses an automatic reclosing system, which relates to the field of power systems, and comprises a first monitoring module, a first control module, a second control module and a controllable switch, and is characterized in that the second control module monitors the state of an incoming line switch to ensure that the incoming line switch is in an off state; whether power transmission in the ring main unit is recovered or not is judged through the first monitoring module, the incoming line switch is closed through cooperation of the first control module and the controllable switch under the condition that the power transmission of the ring main unit is recovered, the possibility that a line fault still exists is eliminated, the line safety is guaranteed, and the reliability of the ring main unit is improved. According to the utility model, the safety and reliability of the whole power system are ensured, the mutual cooperation among the modules realizes the automatic closing of the inlet wire
