Instrumentation is a rapidly developing industry. Its position in the society is getting higher and higher. Electronic transformers are part of the instrumentation. There are many experts who are not familiar with the development trend of electronic transformers. Let's introduce it.
Future research directions <br> <br> passive sensing of: sensing because passive technically advantageous manner, freestanding ECT sensor member will tend to passivity, which includes an active sensor through the external source is out of Dependence, self-power supply, quasi-passivation, the average life cycle of electronic transformers will reach more than 10 years. The optical sensor controls the engineering network by improving its measurement performance. All rights reserved. Simplifies the system structure and reduces the cost.
Structural composition: Utilizing the advantages of electronic micro power and miniaturization, transformers are more modularly combined in transformers, fully-enclosed combination appliances, isolating knives, etc., to reduce the area, and to reduce the cost. Through the reuse of functions, the miniaturization and intelligence of the primary appliance itself are promoted. Various programs will exert their advantages while also combining with each other's advantages. In addition to various independent and enclosed current-voltage combination transformers, LPCT/ROG-CT and optics are expected to appear in the next few years. Combined current transformers.
Function Reuse: Make full use of the advantages of data sharing, single-point test, multi-point sharing, and transformers provide different types of digital interfaces such as Goose, RS485, and MU, which can be shared by multiple measurement and control devices to reduce multi-point repeated installation of transformers. , Make the device configuration more compact.
Standardization of components: The standardization of transformer components makes it universal and interchangeable. It can be used as a standard accessory to be installed in various primary devices. The transformers of different manufacturers can be replaced and interchanged.
Application <br> <br> statistics, China currently has about a hundred units in the new electronic transformer exploratory research and development, supply capacity of the initial formation there are about ten, categories are more complete, comprehensive supply There are currently 3 to 5 homes. The product involves 10 ~ 800 kV, current, voltage, free-standing, combined appliances and other different varieties.
Since 2004, active electronic transformers have entered the market before the optical transformers. The high voltage side of the active electronic transformer converts the current signal into a digital signal and transmits it to the ground potential through optical fiber. Like the optical sensing scheme, it realizes Optical isolation between high and low voltage insulation, combined with ease of industrial mass production, has become the dominant transformer category.
In the same period, China developed a more practical "self-excited source" technology, thereby transforming it into a "quasi-passive" structure. This solution can greatly simplify the transformers and fundamentally improve the reliability and life cycle.
Soon, an "equipotential cavity" partial pressure structure suitable for electronic low-power partial pressure appears in China. It has very high insulation safety and measurement accuracy, and thus can replace the traditional transformers relying on oil and gas insulation. This technology is particularly suitable for the dry-type of high-voltage, UHV voltage divider structure, is a new electronic voltage transformer from China.
In order to overcome the measurement performance, it is easily affected by temperature and vibration stress. At present, the optical scheme has been improved from a ring-shaped magneto-optic glass to a fiber-optic sensor, making the optical scheme a new technology platform and closer to practical requirements. The electronic transformers of the so-called optical fiber type have been used for a small number of trials and need to further overcome the problems of complicated structure and high cost.
The main problem facing the application <br> <br> electronic transformer to change the way the original assembly applications, such as strong interference sources close to the microelectronic device is moved to the outdoor environment before high-voltage lines, isolator, breaker, etc., must Under severe weather conditions and irregular strong electromagnetic interference test, the main problems faced in the current research and development of electronic transformers are: electromagnetic interference protection, communication error control, reliable power supply methods, and adaptability to the outdoor environment. If the measures are improper, it is easy. Cause signal failure, protection misjudgment, rust aging and so on.
To solve these problems, we need to improve the test as soon as possible, test relevant standards, and promote the next step in the development of electronic transformers to the high reliability, high stability direction.
