Description

technical field [0001] The invention relates to the field of communication equipment research, in particular to an intelligent communication power monitoring device. Background technique [0002] In power plants and substations, there are a large number of dispatching commands and operating data that need to be transmitted interactively. To complete such interactive transmission, 48V communication power supply is inseparable. The linear power supply converted from low voltage or the switching power supply converted by high frequency oscillation are both of high importance and high cost. At the same time, due to the heavy load and many branch lines, they are subject to impact short circuit and wet ground fault phenomenon. happens sometimes. [0003] In the prior art, when a fault occurs, it is mainly to rely on manual switching and power off one by one to find faulty lines, which is both cumbersome and complicated, and causes normal lines to be implicated and affected, which...
