Abstract
The utility model relates to a monitoring system for a power supply and distribution line. In the prior art, the running state and the power supply state of the equipment of a power supply and distribution system cannot be accurately known and controlled. In order to solve the above problem, the utility model develops a monitoring system for a power supply and distribution line. The monitoring system comprises a monitoring host, a current detector, a current transformer, a switch change-over acquisition module, a switch, a digital value acquisition module and a lightning protection device. The monitoring host is respectively connected with the current detector, the switch change-over acquisition module and the digital value acquisition module through an RS485 bus. The current detector is connected with the current transformer. The switch change-over acquisition module is connected with the switch. The digital value acquisition module is connected with the lightning protection device. Due to the adoption of the above technical scheme of the utility model, not only the on-off condition of a loop switch, but also the fault state of the lightning protection device, can be effectively monitored.
