The low-voltage centralized metering operation and maintenance simulation training device is developed and designed by our company based on the relevant technical specifications of low-voltage centralized metering and autonomous operation and maintenance of power grid customers, integrating the relevant technical requirements of type I and II concentrators, type I and II collectors, single-phase and three-phase remote fee control smart meters, carrier meters, and micro-power wireless energy meters in the metering automation collection system. The device configures various communication schemes for low-voltage centralized metering collection based on the typical design of low-voltage centralized metering projects, and freely networks the type I concentrator scheme and the type II concentrator scheme. It has the characteristics of full fault types, wide coverage, and full collection schemes. It is a multifunctional centralized metering and autonomous operation and maintenance training equipment that integrates training and learning, theoretical verification, practical skills, and assessment and appraisal.
