Intelligent, rewrite the switch industry pattern

Guide: it is self-evident that smart electricity has brought great changes to the power industry, and the most direct is the power equipment industry. Switchgear is an important equipment in the construction of intelligent electricity. What impact has the construction of intelligent electricity brought to the technological development and industrial layout of switchgear? How should enterprises deal with it

how big is the boundary between primary and secondary equipment

the construction of smart electricity has brought changes to the switch industry, the most obvious of which is the change of industrial layout. In the future, the primary equipment will contain some intelligent units of secondary equipment. At the same time, for the whole field of secondary equipment, some functions of secondary equipment are transferred to primary equipment and integrated into more integrated intelligent units

the primary equipment will promote the design technology of the secondary equipment, and the secondary equipment will also achieve an overall breakthrough in technology, becoming more information-based and interactive. The improvement of technology will enhance the protection function of the equipment and make it more interactive and relevant. Zhoufengquan, director of the smart electricity research center of China electric equipment XJ Group, told

due to the strengthening of relevance, the industrial layout of switchgear manufacturers has also changed. There will be more consortiums of switchgear manufacturers, and the primary and secondary equipment will cooperate closely. The trend of the switchgear industry is to integrate and not subdivide the primary and secondary manufacturers, similar to abb and Siemens now. Yin Junhua, head of the Intelligence Department of Pinggao group, told

the integration of primary and secondary makes the technology of the switch industry must make continuous progress to meet the requirements of intelligent electricity. Sensing technology, state detection technology, microelectronics technology and so on are all new topics facing the switch industry. Technically speaking, smart electricity puts forward higher requirements for switching technology. Primary and secondary compatibility. More research should be carried out on key technologies, such as sensing technology, state transmission and diagnosis technology, which is still immature and far from practical. Yin Junhua said frankly that since the switch will eventually be applied to the intelligent substation, it also needs to be integrated and debugged with the intelligent substation as a whole. TBEA's high-tech products and services have entered more than 70 countries and regions such as the United States, India, Russia, Tajikistan, Angola, etc., which still needs further research and development

what measures should enterprises take

the huge investment in the construction of smart electricity in China has provided a powerful driving force for the technological transformation of power equipment manufacturing enterprises. According to statistics, by 2020, the State Grid Corporation of China will invest more than 4trillion yuan in the construction of smart electricity, and the project construction requires a large number of transformers, switches and other equipment. It is roughly estimated that the equipment investment will account for 40% of the total electricity investment, which provides a strong financial support and development impetus for the primary and secondary power equipment industry

market demand drives R & D, but technically, enterprises still have a lot to do. Interviewing the technical principals of many switch manufacturers, they said that the condition monitoring and evaluation technology is very important for the intelligent switch. In addition, the testing, debugging and detection technology needs to be improved

at present, the integration of primary and secondary technologies is not so close, and the professional boundaries between designers and users for primary and secondary are relatively clear. Enterprises should pay attention to basic technology research and development, pay attention to forward-looking technology accumulation, and improve the reliability of equipment. In this regard, enterprises need to do a lot of work. Said the technical director of Xi'an Xikai High Voltage Electric Co., Ltd

at present, only some large-scale primary equipment manufacturers are doing research and development in this area, which is beyond the reach of small manufacturers. The person in charge of a small switch manufacturer told that due to the limitations of technology, capital and other conditions, the research and development of intelligent switches can only stagnate in the technical specification cecs102:2002 for steel structures of light-weight buildings with gabled frames

in the final analysis, the progress of technology depends on talents. However, it is also talents that give switchgear manufacturers the biggest headache. In the interview, the person in charge of the switch manufacturer unanimously said that there are too few compound and integrated talents. Now both the R & D side and the user side consider the primary and secondary separately, which is not conducive to the R & D of intelligent switches. Therefore, in terms of talent training, we should also increase the mode of school enterprise cooperation, strengthen the integration of industry, University and research, and cultivate compound talents

high functional integration is the development direction

bright news: what are the benefits of smart electricity for the switching industry

Yin Junhua (director of the Intelligence Department of Pinggao group): first of all, due to the integration of primary and secondary equipment, many functional components on the switch are not needed, which saves a lot of copper and reduces the land occupation. Second, the standardization of the external interface of the switch is improved, which makes the design and debugging of the switch more convenient, and the error rate and maintenance workload are also greatly reduced. Third, the switch realizes the perception and evaluation of its own state, and can interact with electricity to achieve information. While improving its own reliability, it improves the reliability of electricity operation, improves power quality, and reduces operation and maintenance costs

bright news: what are the difficulties in promoting the intellectualization of switches with high guiding accuracy

Yin Junhua: at present, many technologies still need to be developed, such as state detection and Chen Weidong's notification and evaluation technology, controllable control mechanism technology, etc; Due to the limited experimental conditions and fault data, the effective detection method of the equipment is not mature; The relevant standards of switches have not been unified, which is not conducive to the overall development of the industry; In addition, it is also necessary to continue to conduct field research on the construction environment of intelligent substations. The requirements for equipment vary with the construction location of intelligent substation. The substation environment is different from each other, and the reliability of switchgear in extremely high temperature or extremely low temperature environment needs to be improved

bright news: what is the development direction of the intelligent switch industry

yinjunhua: the function integration of intelligent switch will be higher and higher. Its development direction can be summarized as the following characteristics: miniaturization, interface standardization, intelligent action, state visualization, function integration, application automation
