Passive electric leakage monitoring circuit used in cooperation with acquisition terminal

The invention discloses a passive electric leakage monitoring circuit used in cooperation with an acquisition terminal. According to the technical scheme, the passive electric leakage monitoring circuit comprises an electric leakage monitoring circuit body, a rectifying circuit and an MOS tube driving circuit. The electric leakage monitoring circuit body can monitor abnormal current change of a strong current line, and is simple in circuit and quick in response. The rectifying circuit adopts a bridge type rectifying method to rectify alternating current small signals collected by a residual current transformer, the circuit structure is simple, and the rectifying efficiency is high. The MOS tube driving circuit can quickly respond according to the change of the input signal, when the electric leakage phenomenon occurs, the input signal drives the MOS tube to be conducted, the level change of the output signal can be collected by the acquisition terminal, the acquisition terminal forms an alarm event and report
