Let's Take A Look At The Fault Detection Technology Of Transformer
(1) Online monitoring technology
On-line monitoring technology mainly uses vibration analysis method and partial discharge detection method. One is the vibration analysis method. This analysis method refers to monitoring the strength of the vibration signal of the transformer when the transformer is running, and analyzing and summarizing the reasons for such monitoring results, and then real-time detection of the operating status of the transformer, which is conducive to timely detection of faults. The minor faults are resolved before they become major faults. The second is the partial discharge detection method. This detection method refers to the failure of the internal machinery of the transformer during operation, which in turn triggers a partial discharge phenomenon, which will affect the level and speed of the discharge. Therefore, it is necessary to strengthen the daily and effective judgment of the partial discharge of the transformer, detect whether there are hidden safety hazards in the transformer, and solve these problems in a targeted manner to ensure the safe and stable operation of the machinery.

(2) Gas chromatograph technology
Gas chromatograph technology is mainly used to analyze internal components in mixed gases. The advantages of the detection technology are mainly effective in the following points: high efficiency, convenient use, convenient operation and many other aspects. These advantages have promoted the wide application of this technology, and it has been widely used in the detection of various electrical equipment. Applications. Among them, the polymer membrane technology is effectively used to effectively and quickly decompose the oil and gas, and dissolve the oil under the action of the polymer and under the influence of the transformer, which can effectively improve the fault gas and The concentration of gas in the oil. In most cases, when the transformer fails, it may emit the smell of hydrogen gas. Using this chemical characteristic can better detect the gas content and effectively detect the hydrogen in the transformer fault gas. In addition, the use of the transformer to detect a variety of gases greatly increases the diffusion speed of the transformer fault gas, which is beneficial to the recovery of the normal operation state in time.

(3) Sensor array technology
For the sensor array technology, the technology also plays a very important role in the transformer fault detection technology. For this reason, electric power inspection and maintenance workers need to master this technology proficiently, and apply this technology scientifically and rationally to the work of detecting faults, which can effectively improve the safe operation index of the transformer, so that the operating state is not affected by external interference. And because this sensor has the following advantages: high selectivity, high sensitivity, etc., using the sensor for online detection, thereby increasing the speed of detecting the concentration of the faulty gas, which is conducive to the detection of the content. It can be seen that not only can the detection speed be improved, but also It can also improve the technical level of transformer fault detection and reduce the probability of transformer fault detection.

(4) Infrared spectroscopy technology
Infrared spectroscopy technology is also called infrared spectroscopy on-line detection technology. This technology has the advantages of fast detection speed, high accuracy, high sensitivity, and low maintenance. This technology also plays an important role in transformer fault detection technology and helps It is used to detect the content of gas generated by transformer failure. In the actual detection work and in the specific use process, the infrared gas analysis instrument and the pun film capacitance detection instrument can be effectively used for quantitative analysis.
