  • Detail

Recently, entrusted by the Electric Power Research Institute of Shanghai electric power company, the China instrumentation industry association organized and held two scientific and technological achievements appraisal meetings in Shanghai, namely, "intelligent testing laboratory for low voltage metering boxes and key components" and "key technologies and applications for automatic verification of high voltage transformers for measurement". Recently, entrusted by the Electric Power Research Institute of Shanghai electric power company, China National Instrument and meter industry association, for example, used plasmon nanostructures for infrared stealth, organized two scientific and technological achievements appraisal meetings in Shanghai, namely, "intelligent testing laboratory for low-voltage measuring boxes and key components" and "key technologies and Applications for automatic verification of high-voltage transformers for measurement". The appraisal committee is composed of 9 experts in the fields of electricity, measurement, instruments and meters. Professor Zhao Wei of Tsinghua University serves as the chairman of the appraisal committee, and researcher He Qing of China Academy of Metrology serves as the vice chairman of the appraisal committee. The experts of the appraisal committee listened to the report of the achievement completion unit, reviewed the appraisal materials, visited the site, inspected the operation and demonstration of the achievements, and questioned and discussed

Figure 1 the "intelligent testing laboratory for low-voltage metering boxes and their key components" on the site of the results appraisal meeting was jointly developed by the Electric Power Research Institute of Shanghai Electric Power Company and Yantai Dongfang Weston Electric Co., Ltd., which realized the full-automatic testing of low-voltage metering boxes and their key components of different specifications, fully covering the full performance test items of low-voltage metering boxes and the performance test items of external circuit breakers specified in the national standard, It can carry out full performance, sampling and sample comparison, which can reduce the input of inferior products and better provide objective and scientific basis for the input, selection and quality evaluation of metering box and external circuit breaker

Figure 2 the appraisal committee inspected the Intelligent Testing Laboratory of low-voltage metering box and its key components on site.

"key technologies and applications for automatic verification of high-voltage transformers for measurement" was jointly completed by the Electric Power Research Institute of Shanghai Electric Power Company and Hongxiang Co., Ltd, The developed automatic verification system of high-voltage mutual inductors for measurement has realized the automation and intelligence of the whole process of verification of high-voltage mutual inductors for measurement, which has become an increasingly complex motor system. It can carry out the full-automatic verification of various types of 10kV ~ 35kV measuring mutual inductors according to the requirements of the national measurement verification regulations, and the production capacity can be flexibly configured and expanded according to the production demand

Figure 3. The two achievements of the automatic verification system of high voltage transformer for measurement made by the appraisal committee on site have been successfully applied in Shanghai electric power company, with significant economic and social benefits

the appraisal committee believes that the two research results have reached the international advanced level on the whole, and unanimously agreed to pass the appraisal, and recommended to further accelerate the popularization and application of the results

attachment: brief introduction of achievement units

the Electric Power Research Institute of Shanghai electric power company mainly undertakes the measurement value transmission and technical management, electric technology and equipment status detection and evaluation, scientific research and development and information services, technical supervision and services related to power plants, etc. of Shanghai electric power company. The measurement center of Shanghai Electric Power Research Institute (sepri) is an electric energy measurement technology management organization with a long history. It takes the lead in implementing the intensive management of electric energy measurement instruments in China, is responsible for the quality supervision and management of electric energy measurement equipment, and is responsible for the unified and centralized management of the procurement, verification and distribution of electric energy measurement instruments such as electric energy meters, mutual inductors and acquisition equipment within the scope of Shanghai electric power company

Yantai Oriental Weston Electric Co., Ltd. is a national key high-tech enterprise engaged in energy measurement and management and environmental protection and energy conservation, integrating product R & D, production, service and sales, and a pilot enterprise for the integration of industrialization and informatization of the Ministry of industry and information technology. At present, the company is one of the manufacturers with complete varieties, advanced technology and perfect functions of domestic energy measurement products. Its products have been sold to nearly 1000 users in the fields of national power, southern power, local power, communication, high-speed rail, airport, University, port, Oilfield Petrochemical, steel and coal, and have successfully entered the overseas markets of South Asia, Southeast Asia and Africa. It has participated in and completed a large number of national key projects, such as the Three Gorges power plant, the Beijing Olympic Games, the Shanghai WorldExpo and the Guangzhou Asian Games

Hongxiang Co., Ltd. is a national high-tech enterprise, which has long been committed to the research and application of power system condition based maintenance technology, and can provide customers with comprehensive solutions for condition based maintenance and intelligent operation. It can provide customers with four kinds of intelligent electric condition based maintenance series equipment, entrusted testing service, professional consulting service and the establishment of an effective electric equipment risk prevention management system, which also facilitates the worry business mode that the majority of users are far from being able to see the machine, so as to meet the diversified needs of power enterprises such as on-site detection, application management and business decision-making. The company's spring materials for condition based maintenance and the maximum experimental force of different sizes are different? The series of products have been successfully applied to the power supply guarantee projects of the Shanghai WorldExpo, the Guangzhou Asian Games and the Xiamen BRICs summit
