Electric energy metering device remote monitoring diagnostic system and working method thereof

Abstract

The invention provides an electric energy metering device remote monitoring diagnostic system which comprises an electricity consumption information acquisition system, a communication server, a data acquisition and analysis server, a database server, a service information server, a Web server, a workstation computer and data buses, wherein the electricity consumption information acquisition system is used for transmitting data through the communication server and the data acquisition and analysis server; and the data acquisition and analysis server, the database server, the service information server, the Web server and the workstation computer are electrically connected with each other in a signal connection manner through the data buses. A working method of the system mainly comprises the steps of acquiring data, calling data, analyzing, warning faults and outputting retroactive electric quantity information. According to the system and the method, the promptness of the electric energy metering device fault discovery and processing is improved and benefits are brought to improve the electric energy metering monitoring and management level of the power supply units, decrease the electric quantity retroaction disputes, save a mass of man power and material resources, improve the work efficiency, reduce the loss and improve the efficiency.

Description

technical field [0001] The invention relates to the technical field of electric power supply metering and monitoring, in particular to a system for remotely monitoring, analyzing and diagnosing the operating status of an electric energy metering device and a working method thereof. Background technique [0002] The electric energy metering device at the power user site usually includes a transformer, a secondary circuit and an electric energy meter. Therefore, common electric energy metering device faults include transformer faults, secondary circuit faults and electric energy meter faults accordingly. Transformer faults are generally inter-turn short-circuit of a certain mutual inductor, high-voltage fuse of the transformer, disconnection of the zero line of the transformer, etc.; secondary circuit faults are usually wiring errors, repeated grounding of the current transformer circuit, and secondary line disconnection and secondary line breakage cause shunt, etc.; common f...
