Electronic transformer on-line monitoring device and monitoring method

Abstract

The invention relates to an electronic type transformer online monitoring device and monitoring method. The electronic type transformer online monitoring device comprises a first digital signal processing plug-in connected with electronic type transformers, an internal data monitoring unit connected with the electronic transformers, and a central processing unit plug-in which is in data connection with the first digital signal processing plug-in and the internal data monitoring unit through a field bus. According to the electronic type transformer online monitoring device of the invention, the first digital signal processing plug-in and the internal data monitoring unit which are connected with the electronic transformers respectively are adopted, the physical parameters such as current, voltage, electric state quantity, temperature, humidity, pressure intensity and strain of the plurality of electronic type transformers can be monitored in real time, and the data information is fused, so that the operating states of the electronic type transformers can be comprehensively analyzed and judged, and a failure analysis report and a comprehensive fault statistics report can be outputted, and therefore, power outage time and frequency can be reduced, and the use efficiency of power equipment can be improved.

Description

technical field [0001] The invention relates to the technical field of on-line monitoring of electric power equipment, in particular to an on-line monitoring device and method for electronic transformers. Background technique [0002] In recent years, electronic transformers have been applied and promoted to a certain extent in power grids. Electronic current / voltage transformers have been used in some projects and pilot projects, but some problems have also been exposed during operation. The most prominent one is the reliability problem, which is mainly manifested in: the electronic transformer fails to detect its own faults in real time and conduct fault analysis and judgment during field operation; lack of long-term stability evaluation of electronic transformers. [0003] During the implementation process, the inventors found that there are at least the following problems in the traditional technology: electronic transformers are mainly used to measure parameters such as...
