Listen to low-voltage electrical core "jump" sound

What is the direction of the upgrade of Yueqing Electric Industry, known as the “First Industry of Wenzhou”? The pilot project of transformation and upgrading of the blocky economy in Yueqing, Zhejiang Province, which was launched on December 2th, indicates the direction: intelligentization, embedding chips in low-voltage electrical equipment such as circuit breakers and switches to achieve self-safety diagnosis.

According to statistics, currently Yueqing has a total of more than 6,000 electrical and related supporting manufacturing enterprises, including more than 1,300 enterprises above designated size, 61 enterprises with annual output value exceeding 100 million yuan, 5 companies entering the top 500 Chinese enterprises, and 13 enterprises among 500 private enterprises in the country. Qiang is the largest electrical industry base in the country. Last year, Yueqing's industrial electrical industry realized an output value of 50.9 billion yuan, accounting for more than 65% of the total output value of the province's industrial electrical industry. Its core products, low-voltage electrical appliances, have accounted for more than 60% of the national market share for many years.

In order to transform and upgrade modern industrial clusters, last year the Zhejiang Provincial Government included the Yueqing Industrial Electrical Industrial Cluster as a list of the first batch of 21 well-known massive economic transformation demonstration zones in the province. Recently, the Provincial Department of Science and Technology commissioned the City Huanyu Group to undertake the experimental work of Yueqing industrial electrical upgrading. It dispatched eight experts including Hebei University of Technology and Wenzhou University to provide intellectual support and launched a two-and-a-half-year “low-voltage electrical equipment for intelligent distribution network. "Research and development and industrialization" research, the creation of a demonstration project of intelligent low-voltage power distribution system, to lay the foundation for winning the national smart grid construction business opportunities.

“The circuit breakers and switches required by the smart grid low-voltage power distribution system will be implanted with chips and software programs. Under the framework of the information network, remote control, real-time transmission of technical indicators, self-safety diagnostics, and automatic detection of failures Send prompts and activate standby lines at the same time to ensure the security of the power grid.” Professor Wu Guichu, a member of the expert group, of the School of Physics and Electronic Information of Wenzhou University, told reporters that this research and development brought together experts in electrical automation, electronics and IT networks. It is the integration of communication technology, sensing and measurement technology, computer technology and control technology with the original power grid to form a new type of local smart grid, and build a smart grid with strong anti-interference ability, safety, stability and self-healing and interactive functions. Low voltage distribution test platform.

At the launching ceremony, chief expert of the expert group and Professor Lu Jiguo of Hebei University of Technology introduced that research on R&D and industrialization of low-voltage electrical equipment based on intelligent distribution network has just started in the international community, and there is no complete research result. Innovative design is intelligent and low pressure. The distribution system and intelligent electrical components will help Yueqing Electric win the national smart grid construction market.

"It is expected that the company will add 30 million yuan in annual output value and increase annual profits and taxes by 5 million yuan." Wang Tuoyu, president of Huanyu Group, said that for Yueqing Industrial Electric, the research and development results will significantly increase the added value of low-voltage electrical products in Yueqing. The large-scale intelligent low-voltage electrical appliances will effectively promote the upgrading of the Yueqing industrial electrical block economy to modern industrial clusters. Not only do they have huge economic benefits and greater social benefits, they can seize opportunities for global smart network construction and compete with internationally renowned enterprises.
