Wind power equipment industry changes the direction of multi-transformer

In recent years, the prices of core materials and conductive materials used in electronic transformers in power supplies have continued to rise, and upstream raw materials have formed a seller’s market. As a power supply user of downstream electronic transformers, they can select and purchase globally to form a buyer's market. In the middle of the electronic transformer industry, only take the road of technological innovation to get rid of this dilemma. However, in the mature electronic transformer industry, technological innovation is more difficult. However, the improvement of every small link can bring new ideas and new products.

After more than 50 years of development, the low-voltage electrical industry has formed a relatively complete industrial system. Its products are widely used and have huge market potential. The research and development of high-end products will remain the main direction of the industry in the future. Smart products become a trend, and intelligence will become the main direction.

Presenting features Low-voltage electrical products are intelligent. In modern power plants and industrial and mining enterprises, electronic computer monitoring systems have been widely adopted, and high-performance and intelligent requirements have been put forward for the corresponding low-voltage circuit breakers, and the products are required to be protected, monitored, tested, self-diagnosed, displayed, etc. Features.

Electronic products. In a modern enterprise, the use of a PC control system instead of a system consisting of electrical-mechanical components has become the mainstream of mechanical electrical control systems. The system requires electrical products with high reliability and high immunity to interference. It also requires the contacts to be able to reliably turn on low voltage and weak currents. The arc at the time of contact disconnection cannot interfere with the normal operation of the electronic circuit.

Product composition and modularization. Combining different functional modules into modular modular appliances according to different requirements is the development direction of today's low-voltage electrical appliances industry. The auxiliary contact assembly, time delay assembly, self-locking assembly, interface assembly, mechanical interlocking assembly and surge voltage assembly are installed on the body of the contactor, which can meet the requirements of different occasions, thereby expanding the scope of application of the product and simplifying the production process. , user-friendly installation, use and maintenance. At the same time, it will further improve product reliability and product quality.
