| By the increment of investment demand and the demand for energy-saving alternative to the double stimulus, as well as the rapid development of EHV, UHV transmission technology, in recent years, power capacitor industry has ushered in the golden period of development, has maintained a high growth trend. Backbone enterprises of gross industrial output value, yield substantial growth year on year, new product development speed. This year, the industry output value and output up continues to grow, showing a good momentum of development.
Industry statistics show that since 2001, the power capacitor industry output annual growth rate of about 20%. In 2007, industry output increased 22.8 percent over the previous year. In the first half of this year, the output of shell capacitor, a collection of box-type capacitor, high-pressure self-healing capacitors, and other products with different degrees of growth.
Technical innovation with remarkable results
In recent years, ABB, Cooper, and some foreign famous enterprises into a strong, local businesses to the power capacitors have a great impact. In order to reverse the passive situation, a group of backbone enterprises have invested a lot of funds , on the one hand, the construction of a new production line to vigorously expand production capacity; the other hand, the intensity of technological transformation and the acquisition of world-class production equipment and process equipment.
According to incomplete statistics, last year, the technological transformation of the industry to invest 135 million yuan, mainly for updating technology and equipment. In recent years, imports nearly 20 of the world’s most advanced automatic element winding machine, more than ten sets of Germany’s most advanced vacuum processing and oil-soaked equipment. At present, the production equipment of the industry backbone enterprises fully with the international advanced enterprises comparable.
Good level of equipment has injected huge impetus for the development of the industry. Only example in 2007, the industry’s industrial growth rate of 18.6%; sales revenue growth of 24.3 percent over the previous year; total industry profit growth of 10.2 percent over the previous year. The large number of enterprise value of a substantial increase in output value of more than 100 million yuan, 9, the highest in more than 800 million yuan.
Innovation intensified
In recent years, the rapid development of the domestic HVDC Transmission Project, the power capacitor industry provides a rare opportunity. Tian Guang, your Canton "," three wide "project project shunt capacitor device, the filter capacitor device 750 kV 0.2 capacitive voltage transformers, 10 kV standard capacitors, high and low voltage reactive compensation devices, high, low voltage AC filtering devices, such as a number of new products in the key state AC and DC projects put into application, and runs well.
Continue to improve with the electric power construction on the voltage quality, safety and power requirements, especially in countries vigorously implement the energy saving policies, complete sets of equipment of the power capacitor technology has improved continuously since spawned a number of environmental protection and energy saving products . Last year, the complete sets of equipment (mainly refers to the production of reactive compensation devices and filtering devices) increased by 27.2 percent over the previous year.
The face of increasingly stringent safety standards for power grid, as well as stringent energy saving requirements to meet the urgent need for parallel and filter capacitor device market, the industry is actively developing high-tech products, completed the production of high pressure shunt and filter capacitor of 79630 trillion spent, an increase of 14.3 percent over the previous year. Among them, Xi’an XD Power Capacitor Co., Ltd., Guilin Power Capacitor Co., Ltd., the new motor ( tin ) Co., Ltd. production industry, high pressure shunt and filter capacitor more than 50% of the total production.
(From: China Industry News) It is worth mentioning is the backbone enterprises to actively strengthen technological innovation to overcome many technical difficulties, the successful production of one million volts grade capacitor voltage transformer.
According to statistics, nearly three years in the industry through national, provincial and municipal identification of new product 32. Xi’an XD Power Capacitor Co., Ltd. developed BAM6.35-800-1W shunt capacitor, DAM9.299-81W DC filter capacitors, DAM15-18.1W DC filtering capacitor to reach domestic advanced level of similar products; ZOAF500- 0.05H DC coupling capacitor, the capacitor voltage transformer in TYDL110/-0.02H TYDL500/-0.005H capacitive voltage transformer fill the gaps and reach the advanced level of similar products.
Energy conservation is still the focus Huge market demand in
, as well as the industry’s technology level increased dramatically, the industry was extraordinary development. But generally speaking, part of the enterprise of scientific research efforts in basic research is still relatively weak, some new products and complete sets of equipment is not high tech. The product of media research, key technology research, product and health aspects of the investment is insufficient, the product level is always a certain gap with the international advanced level.
Currently the country to speed up the pace of energy-saving emission reduction, energy conservation efforts to promote unprecedented. In this backdrop, the focus on market demand, high-tech armed enterprises, and promote the implementation of energy saving policy, it will be the future direction of development of the power capacitor industry. To this end, we must continue to increase independent innovation, enhance production, learning and research, "the combination, and vigorously develop the high reliability, high technical content and high level of automation, energy saving, environmental protection and reactive power compensation device to promote the industry continue its rapid development.
Future industry technology R & D focus, efforts to improve the technical and economic indicators of the capacitor, in a single 500 kvar than the characteristics of 0.2 kg / kvar capacitor stable production and reliable operation on the basis of the development of a single 700 1000 lack of, than the characteristics of 0.18 kg / kvar capacitor; strengthen basic research, in-depth study of the internal fuse, outside fuses, capacitor bank protection, overvoltage protection and capacitor device noise and other topics.
At the same time, we should vigorously promote the capacitor in-depth study of the media, to improve the stability of the film thickness uniformity and electrical properties; vigorously develop the AC-DC UHV transmission power capacitors, the focus is ± 800 kV DC filter capacitor device, for valve with both pressure and damping capacitor, AC filter capacitor single capacity, the implementation of the anti-leakage measures to ensure that the annual failure rate is reduced to less than 0.2%.
A period of time in the future, you want to continue to implement the collection of capacitors corrective measures, so that the electrical breakdown failure rate is reduced to less than 0.2%; promote the adoption of the main load side compensation, to simplify the structure of the main transformer, reduce loss and improve transmission power and improve compensation effect, improve the operational reliability of large-capacity capacitor banks. Will vigorously promote the development of reactive power compensation and filtering devices to advanced reliability, the choice of the switching switch is not renewed, a reasonable choice of different types of reactors, improve the reliability of the series reactor operation. At the same time, accelerate the R & D SVC of STATCOM reactive power compensation device with advanced performance. |
