Voltage transformer

Abstract

The invention relates to a voltage transformer. The voltage transformer comprises a sulfur hexafluoride inflatable voltage transformer main body, a sulfur dioxide electrochemical sensor and an AT89C51 single-chip microcomputer, wherein the sulfur dioxide electrochemical sensor is used for performing sampling analysis on an inflation gas in the sulfur hexafluoride inflatable voltage transformer main body so as to determine the content of sulfur dioxide therein, and the AT89C51 single-chip microcomputer is connected with the sulfur dioxide electrochemical sensor for determining an alarm strategy on the basis of the sulfur dioxide content. Through the voltage transformer, self-detection of parameters can be performed on a sulfur hexafluoride inflatable voltage transformer, and the intelligent level of the voltage transformer is improved.

Description

[0001] This invention is a divisional application of a patent with the application number 2015107864555, the application date is November 16, 2015, and the invention name is "voltage transformer". technical field [0002] The invention relates to the field of voltage transformers, in particular to a 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.

Problems solved by technology

[0004] Sulfur hexafluoride gas-filled voltage transformer is a voltage transformer commonly used at present. However, the structure of the sulfur hexafluoride gas-filled voltage transformer in the prior art is not reasonable enough, resulting in excessive product redundancy and qualified The rate is not high, and at the same time, it lacks its own detection mechanism. For example, it lacks the detection equipment for its own temperature and related gases. It needs to add additional interfaces and corresponding detection equipment to operate, which makes the detection process complicated.
