Double-decker train uses ABB traction transformer for the first timeRapid urbanization has brought about problems such as traffic congestion, air pollution and population expansion, forcing railway operators and infrastructure providers to transport more passengers on already busy rail transit systems. One solution to this outstanding contradiction is to increase the passenger capacity of existing transportation lines.On July 22, 2011, ABB , the world”s leading power and automation technology group, recently announced that Bombardier designed and manufactured the world”s first traction transformer that can be installed on the top of the locomotive for its new generation double-deck EMU train . This train can be used in commuter, regional and intercity rail transit. The use of double-decker trains is a good way to increase passenger capacity. This type of train has the best car seat ratio planning, and the improved acceleration performance of the train also effectively shortens the travel time between stations and expands the coverage of train services.The latest Bombardier double-decker trains have an ABB traction transformer installed on the top. They adopt an extra-wide body and better seat planning. The number of seats per meter of the body ranges from 5 to 5.8, providing more space for passengers. Compared with similar models currently on the market, Bombardier”s new trains can carry 35% more passengers.ABB and Bombardier have a long-standing relationship in the field of traction equipment for regional commuter trains, high-speed trains and railway locomotives. The traction transformer converts the grid voltage from the power grid above the train into the lower voltage required by the train”s traction system, and delivers it to the train”s driving equipment, as well as lighting, heating, ventilation systems, on-board LCD displays, information systems and other electrical system .In order to ensure the continuity of railway transportation and the effectiveness and reliability of the highest level of instant power supply, ABB specially designed traction transformers for OMNEO trains. Compared with the traction transformer on the single-layer SP AC IUM* EMU train provided by Bombardier for the Francilien line in the Paris region of France , the power supply capacity of the new transformer is increased by 25%. To save space, the roof-mounted traction system combines the separate cooling systems for the converter and transformer. This design reduces the number of fans while reducing cost and equipment weight. In addition, in order to save space and facilitate equipment maintenance and control, the transformer will be installed directly on the top channel of the vehicle.Bombardier worked with ABB to complete the design work, and the cabin baffles were installed on the inverter , cooling system and transformer to ensure that these components fit perfectly into the arc-shaped roof and are difficult to see from the outside after installation. In order to solve the problem of the high center of gravity of the double-decker train carriage, the transformer has also been designed accordingly to evenly distribute the weight of the equipment.Swiss ABB will build the largest solar power plant in Northern EuropeSwiss power and automation technology group ABB announced on August 11 that it has built the largest solar power station in Northern Europe at its low-voltage AC drive plant in Finland . The total investment in the entire solar power station project is approximately 500,000 euros, part of which comes from the Finnish government. renewable energy investment fund.ABB Finland”s low-voltage AC transmission plant is located in Helsinki. This solar power station is located on the roof of the factory and has a power of 181 kilowatts. The solar power generated is mainly used to charge the factory”s forklift truck batteries and reduce the peak load of the factory”s electricity consumption.Antti Suontausta, Senior Vice President of ABB”s low-voltage AC drives business, said: “This solar power generation system fully demonstrates the benefits of distributed power generation near power consumption areas. Solar power generation can bring high added value to users, especially for commercial and industrial applications . For buildings, solar power generation can reduce the building’s peak power load.”Finland”s sunshine is not very abundant, but this solar power station can take full advantage of the region”s long sunshine hours in summer. It is expected to generate 160,000 kilowatt hours of electricity per year, which is equivalent to the annual use of 30 local households that do not use electric heating equipment. power. This solar power will be directly integrated into the factory power grid to charge the forklift trucks in the factory, and the excess power can also be used by other equipment.The solar power station uses ABB”s latest string inverters and central inverters, which are designed and produced by ABB”s transmission plant in Helsinki. This is their first application in Finland. ABB solar inverters are mainly used to convert DC power produced by solar panels into high-quality AC power and integrate it into the power grid.
