Cable pit shutoff detection device of transformer substation

The utility model discloses a cable pit shutoff detection device of transformer substation. The device mainly includes: camera, signal detection line, video decoder, treater and display device. The device passes through the camera and gathers the inside video signal of cable pit to the video signal that will gather through the signal detection line transmits to video decoder and decodes and the treater. This video signal is handling the back at the enterprising line display of display device through video decoder and treater to make measurement personnel know the shutoff situation of cable pit. Compared with the prior art, measurement personnel is examining time measuring to the cable pit situation, can go deep into the inside inside video signal of cable pit that gathers of cable pit with the camera to surveing through display device, not needing inside measurement personnel gets into the cable pit, labor - and time -saving provides work efficiency.
