The utility model discloses a join in marriage net line fault positioner, include electric current sensing module, the data acquisition module who links to each other with this electric current sensing module to and the power module who links to each other with this data acquisition module, the electric current sensing module contain printing board luo shi coil and signal conditioning amplifier circuit, the circuit passes from printing board luoshi coil, the induction line electric current produces voltage signal, delivers to data acquisition module after nursing one's health, power module establish including the cover that response the circuit outside gets can the magnetic core, it can continuous power control and protective film piece, rectifier module, first order DCDC module, second level DCDC module, lithium cell and the power management module of magnetic core to get with this response. The utility model discloses can support the collection of electric current phasor, trouble record ripples, remote communications etc. Have traditional fault indicator because the power is limit and the function of unable burden, have better application prospect in future. |
