Microcomputer Integrated Protection Device for High-Voltage Ring Main Units
The microcomputer integrated protection device for high-voltage ring main units is an economical protection device integrating measurement, control, protection, and communication functions. Tailor-made for high-voltage power distribution cabinets at the distribution network terminal, it takes three-stage non-directional current protection as the core and is equipped with functions for monitoring and collecting power grid parameters. It can replace traditional ammeters, voltmeters, power meters, frequency meters, watt-hour meters, etc. Moreover, it can remotely transmit measurement data and protection information to the upper computer through the communication port, facilitating the realization of distribution network automation. According to the characteristics of distribution network power supply, the device integrates the backup power automatic switching function, which can flexibly realize incoming line backup switching and bus-tie backup switching functions.
