Electronic Transformer Condition Monitoring System

Abstract

The invention provides an electronic transformer state monitoring system, which includes a sub-control unit, a main control unit and an output unit; the sub-control unit is used to collect data volume signals and state volume signals of electronic transformers, including unit, state quantity acquisition unit, standard transformer acquisition unit, synchronous interface control unit and wave recording storage control unit; the main control unit is used to monitor, display and store the data volume signal error and working status of the electronic transformer, including control module, a status monitoring module, an accuracy monitoring module and a wave recording monitoring module; the output unit includes a local real-time display unit and a remote real-time display unit. Compared with the prior art, the present invention provides an electronic transformer status monitoring system capable of monitoring multiple electronic transformers, synchronously connecting multiple external devices, accurately monitoring the operating status of equipment, and recording long-term status and burst Faults and remote monitoring of electronic transformers.

Description

technical field [0001] The invention relates to a transformer state monitoring system, in particular to an electronic transformer state monitoring system. Background technique [0002] Electronic transformer is the key equipment of digital substation. It has the advantages of simple insulation structure, no magnetic saturation, large transient response range, small size, and the output signal can be directly input into the interface of computerized measurement and protection equipment. However, due to the long-term operation reliability, service life, and unstable error characteristics of electronic transformers, the problems of operation and maintenance have not been solved, which has affected the popularization and application of electronic transformers in power grids. [0003] Some key parameters (such as insulation status, key components working status, power supply, etc.) The gradual deterioration will eventually lead to transformer failure, and in severe cases, it wil...
