Plastic tube float flowmeter thus replaces traditional transformers that rely on oil and gas insulation
2012-4-10 13:50:40

代替油、气绝缘。 Optically isolated plastic tube float flowmeter replaces oil and gas insulation. Independent high-voltage transformers use optical fiber digital connections once and twice. Optical isolation replaces complex and expensive oil and gas insulation systems. This is a revolutionary change. The higher the voltage, the higher the cost-effectiveness of the transformer. The small signal transmission replaces the high power output. The miniaturization and low power of the transformer can reduce the weight of the original tens of kilograms or even tons to a few kilograms. The word output replaces the analog output, which is convenient for subsequent network connection and intelligent processing. It uses optical fiber transmission and has stronger ability to resist electromagnetic interference. Network data sharing replaces multi-winding parallel wiring. Single-point measurement data of electronic transformers can be transmitted via Industrial Ethernet, so they are shared, and a large number of parallel cables can be omitted at the power station.


项目的外部性问题进行了细致调查的基础上,《中国塑料管式浮子流量计项目立项申请报告》充分论证了项目可能造成的一系列社会、经济影响,并对塑料管浮子流量计项目外部性论证的结果做出了客观评价。 Based on a detailed investigation of the external problems of the plastic tube float flowmeter project, the "Application Report for the China Plastic Tube Float Flowmeter Project" fully demonstrates a series of social and economic impacts that the project may cause. The results of the externality demonstration of the tube float meter project were objectively evaluated. The report's description of the project mainly includes the following parts: 1. The operating financial status of the project reporting unit and the basic introduction of the project. Second, the project industry environment. Mainly expounded are the industry policy provisions of the project. 3. Project resources, energy, land use plan and impact. The project's resource utilization, energy conservation, and rationality of land use were discussed in detail to examine whether the implementation of the project is in line with relevant national planning policies and is conducive to sustainable economic and social development. 4. Environmental, economic and social impacts of the project. Regarding the environmental impact of the project, the report not only objectively analyzes the types of pollutants and the amount of pollutants that the project may produce, but also proposes measures to control the pollution. In the discussion of the project's economic impact, the report gives a detailed discussion from the project's overall economic impact, industry impact, and regional impact. In the discussion of the project's social impact, the report not only discussed the impact of the project on the employment and income of social residents, the impact on regional science, education, culture, health, etc., but also discussed the social compatibility of the project, social risks, and proposed social risks Countermeasures.

和测量精度指标,因而可以替代传统依靠油、气绝缘的互感器。 Soon, a kind of "equal-potential cavity" partial pressure structure suitable for electronic low-power partial pressure appeared in China. It has high insulation safety plastic tube float flow meter and measurement accuracy index, so it can replace the traditional oil and gas reliance. Insulated transformer. This technology is particularly suitable for the dry type of high-voltage and ultra-high-voltage voltage divider structures. It is a new type of electronic voltage transformer that has grown out of China. In order to overcome the measurement performance susceptible to temperature and vibration stress, the optical solution has been improved from a ring magneto-optical glass to a fiber-optic sensor, making the optical solution a new technical platform, closer to the practical requirements. A few types of electronic transformers known as fiber optics have been tried out, and they need to further overcome the problems of complex structure and high cost.
