The invention discloses a DC power distribution monitoring system having a self-adaptive voltage class and a power supply mode for communication. The DC power distribution monitoring system comprisesa master control unit, a human-computer interaction unit, a self-adaptive power unit, a bus insulation monitoring circuit, a branch energy consumption and branch switch state acquisition device, a branch ground insulation resistor detection circuit, a voltage acquisition circuit and a current acquisition circuit, wherein the human-computer interaction unit, the branch energy consumption and branchswitch state acquisition device and the branch ground insulation resistor detection circuit all are in bidirectional communication connection with the master control unit, signals acquired by the businsulation monitoring circuit, the voltage acquisition circuit and the current acquisition circuit are transmitted to the master control unit, and the self-adaptive power unit is used for providing aDC power supply for the master control unit. By the DC power distribution monitoring system, the advantage that different power supply modes and different voltage classes are compatible is achieved.
Description
technical field [0001] The invention relates to the field of electric power monitoring, in particular to a communication-use direct current power supply and distribution monitoring system with adaptive voltage level and power supply mode. Background technique [0002] At present, according to different application requirements, there are many power supply and distribution modes and voltage levels for existing DC power distribution equipment. The most common power supply modes are "independent two-way incoming line, two-way outgoing line power supply mode", "single incoming line power supply mode", "main and standby incoming line interlocking power supply mode", "two-way incoming line, single line power supply mode". Outgoing line power supply mode” and so on. The DC voltage level is also gradually derived from the traditional 48V to three voltage levels, 240V and 336V high-voltage DC. The traditional DC power distribution monitoring device adopts different wiring methods o...
