Empty extension tube is connect with the tail end of metal clip, inner containment checkout line；Hollow operations handle is connect with hollow extension tube,
Inner containment checkout line extends export after so that checkout line is sequentially passed through hollow extension tube and hollow operations handle.
The metal clip is made of stainless steel.
It is provided with lighting unit on the miniature webcam.
It is connected using Hooks coupling universal coupling between the metal clip and hollow extension tube.
Further, the Hooks coupling universal coupling uses cross axle type coupling.
The hollow operations handle, which is adopted, to be made from an insulative material.
It is provided with data-interface between the hollow extension tube and hollow operations handle, passes through data line and miniature video camera
Head connection, the data-interface export the image that satellite camera is shot in real time.
The data line is passed through by the inside of hollow extension tube and is connected to data-interface.
In conclusion the visual extension device of relay protection verification provided by the utility model, when relay protection, verification operation personnel exist
It, can be by carrying out clamp operation by the extended hollow operations handle of hollow extension tube, effectively when position in storehouse carries out relay protection verifying work
It avoids operating personnel from being in direct contact with bus bar metal part, prevents electric shock risk；Simultaneously by real derived from miniature webcam
When image see the rheology back side clearly, above bus bar etc. naked eyes blind area, effectively improve processing safety and convenience.
