The invention discloses a system for detecting the state of a gap lightning arrester. The system comprises a passive power supply unit, a parameter monitoring unit, a data relay unit, a background management unit and a state diagnosis unit, wherein the passive power supply unit supplies power to the whole system; the parameter monitoring unit is used for collecting space electric field induced voltage, displacement current and lightning arrester surface leakage current and sending the information to the data relay unit; the data relay unit is used for forming monitoring data by the data sent by the parameter monitoring unit and the real-time acquired environment temperature and humidity, and uploading the monitoring data to a background management system; the background management unit is used for receiving, storing and managing the monitoring data uploaded by the data relay unit; and the state diagnosis unit is used for carrying out algorithm analysis according to the historical monitoring data provided by t
