Abstract

The present invention discloses a power supply method and a device of an RMU monitoring device. The method comprises a step of sensing the first current in a cable in an RMU through a current transformer, a step of converting the first current into a second current through the current transformer, and a step of converting the second working current into working current of the RMU monitoring device, and supplying power to the RMU monitoring device by the working current. Through the method and the device, the problems of complicated wire arrangement in the RMU caused by the need of the external connection of a power supply of an RMU monitoring device in the related technology is solved.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a power supply method and device for a monitoring device of a ring network cabinet. Background technique [0002] With the continuous progress of the society, the rapid development of the national economy, and the widespread application of high-tech in the power system, the utilization rate of the ring main unit is also increasing. The ring network refers to the ring-shaped distribution network, that is, the main power supply line forms a closed ring, and the power supply supplies power to the ring-shaped main line, and then distributes power to each branch through the high-voltage switch control of each distribution branch from the main line. The ring network cabinet is the outlet switch cabinet installed on each power distribution branch road, and the bus bar of this switch cabinet is also a part of the ring main line. Ring network cabinets play an important role in urban power c...
