Light store direct soft future development

Re-examine the new era value of DC system

On the other hand, the rise of light storage direct and soft buildings has made the discussion of AC and DC technology return to the public perspective.

In the late 19th and early 20th centuries, the “current war” between DC and AC raged, with Thomas Edison advocating DC, emphasizing its safety and economy, and Nikola Tesla and George Westinghouse advocating AC, because of its efficient long-distance transmission, easy to adapt to the voltage of the multipurpose and drive motor technology. Finally, with the technical advantages of long-distance high-voltage transmission, AC transformers and AC motors, AC has established its dominant position in the grid and become the international mainstream power supply mode.

REU610CVVHCNP01 Today, with the shift from reliance on fossil fuels to more clean energy, DC application scenarios have been greatly expanded, especially in HVDC transmission, renewable energy grid connection, electric vehicle charging infrastructure, data center power supply and other fields. At the same time, the promotion of the concept of smart grid requires a higher level of intelligence and two-way interaction capability of the power grid, DC system in power electronic control, rapid response and power quality control has potential advantages, more efficient integration of intermittent energy, and more flexibility in the local microgrid, prompting the industry to re-evaluate the choice and integration of AC and DC technology.

ABB has always led the innovation and development of DC special electrical products, advanced manufacturing technology, strict testing, through a large number of DC engineering data analysis and experience accumulation, greatly improved the DC electrical products in increasing the breaking speed, reduce the arc time, improve the arc extinguishing efficiency, DC protection control and other aspects of the performance and parameters. Such as

In the product design concept of DC circuit breaker

REU610CVVHCNP01 ABB DC special air Circuit breaker Emax DC specifically designed DC breaking system, arc extinguishing system, contact system for DC breaking difficulty, designed shunt for DC current measurement principle, developed DC special electronic release for DC protection, to prevent short circuit fault with instantaneous and short circuit delay I3 (instantaneous) and I2 (short delay). G protection function to prevent ground fault.

In the field of micro circuit breakers

In 1924 ABB invented the first modern miniature circuit breaker and obtained the invention technology patent, is the world’s first thermal magnetic technology circuit breaker, today is the 100th anniversary, ABB miniature circuit breaker is now with excellent quality, widely used in construction, industrial and machinery manufacturing, rail transit, data center and home energy storage and other fields, a full range of protection of electricity safety, Become a reliable and worry-free choice for customers.

ABB’s 100th anniversary of the invention of modern miniature circuit breakers, a wide range of DC product portfolio to protect the safety of electricity

Looking at the current energy crisis, greenhouse effect and carbon emissions and other multiple factors driven, light storage direct and soft power system as an effective solution for building carbon neutrality, is expected to promote a new round of energy revolution in the building industry. ABB, abiding by its green commitment, has released scientific net zero targets in 2030 and 2050, advanced DC power technology and a full range of high-performance DC dedicated products, which can not only create a strong building DC distribution network, but also provide one-stop DC distribution solutions to fully meet the various needs of building DC distribution. Moreover, ABB Ability’s innovative digital energy solutions will accelerate the green and low-carbon transformation development of buildings, stimulate the “new quality productivity” of buildings, and open a broader commercial space.
