CABLE FAULT LOCATION DEVICE Russian patent published in 2019 - IPC G01R31/08 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used for determination of fault points in power transmission and communication cable lines. Device is additionally equipped with a remote control unit with remote control buttons Start, Stop, Shutter, Forward, Back, Left, Right. Lead container is made with hooks and is installed on the chassis controlled with the help of the remote control unit, which contains a bearing frame, drive wheels, steering wheels, steering control unit, drive wheels electric drive, two jacks holding the frame. Signal end microswitch is installed on thrust from the side of the lead gate. In lower outer part of lead cover there is lower limit switch, and in lower inner part of lead cover to left of vertical narrowly directed output channel of lead cover there is signal intermediate microswitch. Each jack comprises an electric motor, jack shaft with external lifting thread, two limit switches of extreme top and two end switches of extreme lower positions of retaining frame.

EFFECT: technical result is automation of device control process, reduced probability of radioactive exposure of operator due to possibility of its information on accurate alignment of through, vertical and vertical narrowly directed output channels, as well as prevention of incomplete passage γ-radiation from radiation source and, accordingly, weak effect γ-radiation through earth layer to damaged cable.
