Abstract

The invention provides an electronic transformer redundant device. The electronic transformer redundant device comprises three independent mutual inductors, wherein the mutual inductors are connected with a multi-way signal control module through a data acquisition channel, the data acquisition channel comprises a signal acquisition module, a data processing module and an error calibration module which are sequentially connected, the data acquisition channel is used for transmitting measuring signals output by the mutual inductors to a multi-way signal control module after acquisition and data conversion and a merging unit is used for performing data transmission after the multi-way signal control module is used for performing data fusion and processing on the measuring signals. Compared with the prior art, the electronic transformer redundant device provided by the invention is connected to the merging unit in a self-adaption unit through multi-way optical fiber signals, therefore the reliability of the electronic mutual inductors can be improved.

Description

technical field [0001] The invention relates to an electrical redundant device, in particular to an electronic transformer redundant device. Background technique [0002] Electronic transformers have developed rapidly due to their advantages of simple insulation structure, no magnetic saturation, large transient response range, small size, and output signals that can be directly input into computerized measurement and protection equipment interfaces. Among them, UHV electronic transformer, as an important part of UHV substation, has been more and more widely used. The UHV electronic transformer can be directly connected to the high-voltage busbar and transmission line of the substation. If the UHV electronic transformer fails or fails, it will cause great losses. Therefore, the UHV electronic transformer has poor reliability due to long-term operation. , service life, error and operation and maintenance issues have affected the popularization and application of electronic t...
