subject: The Implementation Of The New Regulatory Power Transformer [print this page] Implementation of new regulations Implementation of new regulations
As we all know, power transformers are used in power transmission to the important electrical equipment, the use of large, long running time, in the choice and use of the existence of a huge energy saving potential. In particular 35 to 220 kilovolt transformer widest range of applications, energy saving potential is higher. Standards in the production of Chinese transformer enterprises sample survey, power transformers, 35 kV voltage class products accounted for 39.8%, 43.4% of 110 kV, 220 kV, 9.6%, more than 330 kV transformer small proportion of the number, which is the scope of the standards to determine the reason for this range now.
"Power Transformer limit value of energy efficiency and energy efficiency rating" provisions of the power transformer limited value of energy efficiency, energy efficiency goal of limited value, energy conservation evaluation values, the energy efficiency rating (divided into 3) and test methods. China Institute of Standardization, TBEA Shenyang Transformer Group Co., Ltd., Baoding Tianwei Baobian Electric Co., Ltd., the International Copper Association (China) Co., Ltd. Xinjiang TBEA transformer plant, the National Network Electric Power Research Institute and so on involved in drafting the standards.
"In pre-market research found that, S9 series electric power transformer power transformer is the production and sale of the mainstream Jilie, while taking fully into account the whole life cycle cost of power transformers, supply chain capacity, energy consumption and industry competitiveness impact factors, will limit the value of the mandatory energy efficiency targets set at the level of S9 series. for now, due to the strengthening of the national energy saving and domestic users in the main power transformer the two grid companies active in energy saving actions , S9 series of threshold values was not high. "involved in the standards of the International Copper Association (China) Project Manager Zhangling Yu told reporters.
It is understood that the standards, energy efficiency, limited market value is the threshold of power transformers, with the energy efficiency grade 3 is the same value, set at the level of S9. The limited value of energy efficiency is in line with China's implementation of "The People's Republic of China Energy Conservation Law" in the system out of energy intensive products set the standard, if the loss of the transformer is higher than the target is considered to be high energy-consuming products, according to energy conservation law, This transformer is not produced or sold.
Energy evaluation index value is recommended in this standard has been set at S10 level, and the energy efficiency grade 2 for the same value. Evaluation value is to implement energy-saving energy-saving product certification and government Caigou the basis for the loss of Deng Yu When the transformer or less than the value O'clock Guiding of Energy Ping Jia, Gaibianyaqi other Zhi Biao Jie He can be energy-saving product certification Jigou assessed for energy-saving products, will be able to enjoy The state encourages energy-efficiency policies, and access to government procurement directory.
In between, there is limited value of energy efficiency goals, as after four years of implementation of mandatory targets, the elimination of high energy-consuming equipment, and promote the role of energy-saving technology a larger target value set at between S9 and S10. Energy class 1 as the development of tax policy on the basis of incentive was set at S11 level.
The standard since December 15, 2009 release, July 1, 2010 began formal implementation.
Earlier in 2006, China has for the 10 kV distribution transformers and implemented the "Distribution Transformer Limited values of energy efficiency and evaluating values of energy conservation" (GB20052-2006) standard. Apart from these two, the country has promulgated standards for energy efficiency of industrial equipment, including motor efficiency standards, energy efficiency standards for clean water pump, ac contactor efficiency standards, energy efficiency standards for industrial boilers.
Significant guidance
The new regulations will be implemented power transformer manufacturing industry in China what the impact? Zhang Lingyu that the standard for energy efficiency under the limit value, not significant.
"As more companies produce power transformers for large manufacturing enterprises, technical strength, there is no barrier, affecting mainly in the increase in production costs and energy consumption Quan Hengshang Syndicated news." He said, "This is only provided for the production enterprises a threshold value, it is important for the next 4 years to improve energy efficiency of limited value to the target to prepare the same time, rising to meet the user's energy requirements, produce more energy-efficient transformers, but also the direction of future development of enterprises. "
According to reports, the level of the main users of power transformers for the power company, its purchasing index higher than the mandatory provisions of this standard, the purchase of transformers, S11 series has a higher ratio.
"I think the significance of the standard is promulgated, on the one hand reflects the national attention on the important electrical equipment and norms, on the other hand, also energy-saving transformer industry has played a good guide. To develop the standard purpose is to guide transformer manufacturers to develop and manufacture high power transformers, transformer inefficiencies out behind. "Zhang Lingyu said.
He also revealed that four years ago and "distribution transformer energy efficiency and evaluating values of limited value and energy efficiency" will face a re-amended, interested parties are doing to implement the results of market research standards. Amendments will involve the limited value of energy efficiency and other indicators of re-enactment, energy efficiency, etc. The classification.
