SEPARATING DEVICE FOR DISTINGUISHING BETWEEN PROTECTIVE AND NON-PROTECTIVE CIRCUIT FAULT

The utility model relates to a separating device for distinguishing between protective and non-protective circuit fault, comprising a main circuit which is composed of a silicon controlled rectifier tube, a triggering capacitor and a protecting diode, a spare branch circuit which is composed of a latching button and a diode, a monitoring circuit which is composed of a neon lamp and an additional resistor. The utility model is used for protecting power station and transformer station and realizing the complete independence of tripping circuit on the wire connection, in order to achieve the purposes of separating and eliminating the influence of protecting and tripping the un-protecting circuit by circuit earthing, short cutting and other various malfunctions.
