Say goodbye to traditional power distribution systems, ABB introduces flexible power distribution solutions

As a high-current conductive product, copper is used in the circuit to transport current and connect electrical equipment. It is an indispensable component behind high and low voltage electrical appliances, power distribution equipment, and electrolytic smelting. If the control cabinet is placed with a brain that controls everything, then the copper platoon is responsible for connecting the staggered nerves to make the system work properly.

With the increasingly strict requirements of the user on the control cabinet, the user hopes that the current distribution system is more reliable and more convenient, while saving space in the cabinet as much as possible, shortening the installation time, reducing the cost and increasing the productivity, which is a huge for the traditional copper platoon. Technical challenges. The advent of ABBDBL power distribution terminals solves this problem, and flexible power distribution solutions offer users a better choice.

Flexible alternative copper bus plan

Gael Grenat, Global Product Manager for ABB Connectivity, said, “It is the original intention to release DBL power distribution terminals to make it easier for customers to distribute power to electrical equipment and components.” DBL product installation and connection speed compared to large-volume traditional copper bars 80% increase and 50% reduction in installation space, because all DBL connection points are concentrated on one compact module, and all connections on the copper bars are lined up in one line, so users can expand more new functions in the control cabinet. The IP20 is protected against touch and ensures safer and more reliable use. DBL-compatible copper and aluminum wire, with a unique modular and compact design, can be used as single-stage, multi-stage shunt and sink, which is equivalent to one product to achieve three functional configurations, saving 20%-30% cost . Product installation is also flexible and flexible, enabling multi-pole interconnection and support for rail and panel mounting.

DBL power distribution terminals are not the first in technology. Currently, similar products exist on the market, but their careful design still ensures that DBL has significant advantages compared with similar products.

See the real chapter for details. At the beginning of the design, ABB engineers focused on every detail of the product. The DBL cover can directly read all the data and technical specifications of the product's maximum current, voltage, recommended torque, stripping length, etc. The reversible cover can be opened from two directions, which can easily tighten the screws. Each product is delivered with a package of printed tag cards (L1, L2, L3, N, PE, +, -) to simplify the identification circuit. In addition, DBL is sufficiently safe for use in high current environments. In addition to its own protection against electric shock, DBL's manufacturing materials use V0 flame retardant plastic, which is commonly used in railway products or explosive environments to meet the requirements of pyrotechnic flame retardant.

Market demand oriented

Each power distribution cabinet needs to be distributed from the main circuit to the secondary circuit. Therefore, the market potential of DBL power distribution terminals is huge, and the global market scale can reach hundreds of millions of RMB. Although the development of DBL power distribution terminals has been dominated by French and Indian technology centers, the demand in the Chinese market is also a key consideration in product development. In fact, in the initial stages of each product development project, local Chinese teams collect market specific needs and key customer information and feed back to the product team, which ultimately reflects part of the product specification. At every stage of R&D, the R&D Center will communicate with the ABB China team to discuss the latest developments and recommendations, and finally make a decision.

Since there is no accessory, the selection of the DBL series is very simple. GaelGrenat reminds users to confirm three standards when selecting the input: the input circuit is rated at 80A-400A, the next generation will be expanded to 500A; the number of cable inputs and outputs is Cross-sectional area, 1-3 wires from 2.5mm2 to 185mm2, the other side 4-12 wires from 2.5mm2 to 35mm2; rated voltage in line with 1000VAC/1500VDC IEC standard and 1000VAC/DCUL standard, can cover almost all current applications. It is understood that DBL is particularly suitable for automation, HVAC, machinery industry, and DC PV strings with packet loops from 600 to 1500v.

Integrating into digital innovation

In addition to meeting current application needs, grasping and responding to the rapid changes in the technology environment and customer expectations is also a quality product and solution, and connected devices are no exception.

In the face of the turbulence of digitalization, ABB officially launched the digital solution ABBAbility, which aims to drive more value chain upgrades across industries by delivering more information through devices, systems, solutions, services and platforms. At the 2017 Hannover Fair in Germany, ABB pioneered the eKover concept, which is to install a smart cover with sensors and a communication module directly on ABB's standard high-current power distribution terminals. The power supply loop collects current data and temperature measurement data in real time and sends the data to the cloud for predictive maintenance and safety warnings.

Another advantage of eKover is that it can work with ABBAbility? The network data monitoring APP of the core-Vision intelligent power distribution cloud platform, the new Emax2 circuit breaker and the Ekip gateway are seamlessly compatible. According to GaelGrenat, “In the future, this digital solution can be applied to other connected devices, using digital technology to complete new technological innovations and create greater business value for customers.”
