Description

technical field [0001] The invention relates to an electric power early warning device, in particular to an underground cable operating environment monitoring and early warning device. Background technique [0002] As one of the important equipment of the power network, the cable is very necessary to detect its operating environment. In the prior art, there are various monitoring systems for cables. These monitoring systems are generally used in overhead lines. For underground cables, Its monitoring is more important. The operating environment of underground cables is relatively closed, and it is difficult to realize patrolling. Although there are some online monitoring systems at present, the stability of the existing technical systems is poor. [0003] Therefore, in order to solve the above technical problems, it is urgent to propose a new technical means. Contents of the invention [0004] In view of this, the present invention provides an underground cable operating e...
