ABB CIRCUIT BREAKERS

Compared with the DC arc, the AC arc has a process of current zero-crossing, and the arc will be extinguished automatically. We only need to take measures to prevent the arc from reburning after the zero-crossing. The DC arc does not have a zero-crossing process, so the DC arc is difficult to extinguish. 

Productivity is greatly improved, while design and installation are greatly simplified at all stages of the product life cycle, from design to day-to-day operations. Save 15% on terminal connection and installation time. Alarm tracking and grid analysis functions ensure work continuity.

Tmax is ABB's molded case circuit breaker with a current of up to 630A. It exhibits excellent performance in a smaller size than similar products on the market. It can be flexibly equipped with electronic or thermal-magnetic trippers to meet various protection function requirements.

The structure of the circuit breaker is made of steel plate, which can reduce the size of the circuit breaker and make it more compact. Double-layer insulation is used to isolate the charged body to enhance its safety, and the phases are completely separated.

ACS510 drives are used in industrial fields and are suitable for various types of loads. ACS510 is also specially optimized for fan and water pump applications. Typical applications include constant pressure water supply, cooling fans, subway and tunnel fans, etc.

In use, the leakage protector should be used in accordance with the requirements of the instruction manual, and should be checked once a month according to the regulations, that is, operate the test button of the leakage protector to check whether it can disconnect the power normally. 

Casting pole features: The use of vacuum disconnection technology can prevent the contacts in the vacuum environment from being oxidized and polluted, and at the same time, the vacuum interrupter can be reliably protected and prevented from mechanical impact, dust, moisture and other potential accidents.

First of all, the structure and dimensions of the circuit breaker and the existing system can be completely matched with each other, which can ensure the coordination and continuity of the appearance. The accessories of ABB miniature circuit breakers are relatively complete, allowing three auxiliary contacts to be installed at the same time.

Digitization and Intelligence of China's Power Grid

According to the overall work deployment of China's digital economy system construction this year and the "Notice on Organizing and Carrying out the 2022 Future Factory Pilot Application in Various Provinces and the Collection of Smart Factory and Digital Workshop Cultivation Projects", after enterprise declaration, local recommendation, and expert review, the Economic and Information Office Determined as pilot enterprises in various provinces to add future factories in 2022
The construction of future factories is one of the main tasks of China's digital reform and digital economic system construction.

For example, some typical discrete enterprises can be customized products, with various specifications and complex management. The construction of the future factory project has deepened the integrated application of a new generation of information technology and traditional manufacturing, which will help the company to break through the traditional production method and management mode of transformers, move towards the benchmark enterprise goal of intelligent transformation in the industry and region, and boost power grid support. The industry is transformed and upgraded in the direction of digitalization and intelligence. At the same time, through the exploration and practice of future factory construction, the company provides models and experiences that can be used for reference and reference for the intelligent manufacturing path of discrete enterprises.
