Embodiment Construction

[0018] Embodiments of the electronic voltage transformer of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] With the continuous application of many new materials, many new types of transformers have emerged, and electromagnetic transformers have been fully developed. Among them, iron-core current transformers have various structures such as dry type, oil-immersed type, and gas-insulated type. Adapted to the development needs of electric power construction. However, with the continuous increase of power transmission capacity, the continuous improvement of grid voltage level and the continuous improvement of protection requirements, the general iron core current transformer structure has gradually exposed its incompatible weaknesses. Weaknesses such as saturation, ferromagnetic resonance, small dynamic range, and narrow frequency band are difficult to meet the development needs of the new generation of power system au...

Abstract

The invention relates to an electronic voltage transformer which includes an electronic voltage transformer main body, an excitation detector, and a Freescale IMX 6 processing chip. The excitation detector is used for performing excitation detection on a housing of the electronic voltage transformer main body. The Freescale IMX 6 processing chip receives an excitation detection result and determines a defect type of the housing of the electronic voltage transformer main body. The electronic voltage transformer can realize self detection of multiple parameters of the electronic voltage transformer and optimize the structure of the electronic voltage transformer.

Description

[0001] This invention is a divisional application of a patent with the application number 201510785106.1, the application date is November 16, 2015, and the invention name is "electronic voltage transformer". technical field [0002] The invention relates to the field of electric power, in particular to an electronic voltage transformer. Background technique [0003] The working principle of the transformer is as follows: In the power supply line, the current difference is from a few amps to tens of thousands of amps, and the voltage difference is from a few volts to several million volts. The current and voltage in the line are relatively high, such as direct measurement is very dangerous. In order to facilitate the measurement of the secondary instrument, it needs to be converted into a relatively uniform current and voltage, and the transformer is used to play the role of variable current, variable voltage and electrical isolation. Most of the display instruments are poi...
