The utility model discloses a high tension cable hole intelligent monitoring system that adoption inclined shaft formula was arranged has adopted modular structure, including alarm subsystem, the supplementary subsystem of intelligent light, wireless communication subsystem, reserve power management subsystem and intelligent electric power network management backstage monitored control system, theplatform has been reserved and have been inserted other independent subsystem communication interfaces, the high tension cable hole adopt the inclined shaft formula to arrange, draw forth towards theground switching station from the main room downstream side middle part that becomes, including flat section, inclined shaft section down with go up flat section. The gaps and omissions that prior art cable hole arrangement form has only vertical mode and horizontal mode has been compensatied for going up a slope and corner also normally high -efficient work in the high tension cable hole, can real -time supervision holds the situation of high -voltage line pipe network deeply, effectively avoids high voltage transmission lines round external damage, can prevent great operation occurence of failure, is particularly suitable for electric power pipe network system on -line monitoring and develops, has wide application prospect and spreading value.
