There are many smaller supporting systems in a turbine, from lift systems used to bring equipment and parts to the nacelle, to circulation fans and internal lighting & electrical connections. ABB products are used throughout these systems.
Motor control and protection
ABB produces safe and reliable products and solutions for all motor applications. These solutions are available for different motor types, and enable different starting methods as well as coordinated solutions for protection and control of motors. Products include AC and DC drives, softstarters, contactors, manual motor starters, back-up breakers/short-circuit limiters, temperature monitoring relays, and overload relays. In addition, motor starters can be integrated on the SMISSLINE plug-in system to reduce space, wiring complexity and installation time.
Low voltage motors
ABB has a large selection of AC motors that are used in turbines. ABB motors are used for hydraulic pumping systems, cooling systems, winches and lift systems, compressors and fan systems.
Low voltage drives
AC drives are used to efficiently and accurately control AC motors. With the widest selection of drives on the market, and support for all fieldbus communication used in turbines, the drives can be intelligently integrated into systems. Using drives reduces startup stresses, and enables precise control of the motor. This results in a more efficient system with reduced mechanical wear helping to ncrease turbine uptime.
ABB softstarters are used for reducing mechanical stress frommotor startup. They reduce initial motor starting current draw and enable smooth motor acceleration and deceleration.
Switch mode power supplies
Switch mode power supplies are used for systems requiring reliable DC power supplies. ABB power supplies use primary switch mode technology that reduces heat loss and increases efficiency. A power reserve of up to 50% protects against loads that have high startup draws on power.
− Wide range of DC output voltages
− Wide range of AC or DC supply voltages
− Suitable for ambient temperature range of -25 to 70 °C
Back-up breaker/Short-circuit limiter
ABB’s short-circuit limiter breakers, WT63 and S800S-SCL-SR, are used for coordinated protection in motor applications up to 690 V, enabling selectivity and minimized installation space when used as back-up for several motor starters.
Push buttons, switches and pilot lights
ABB’s offering of push buttons, switches and pilot lights are used throughout the turbine for control and visual indications.
ABB metal structure enclosures enable easy integration of electrical components especially ABB products. They are available in a variety of sizes, from small wall mounted models to floor standing cabinets. Customization options for doors, cable entry, mounting holes and other items enable manufactures to design optimal installation plans.
ABB terminal blocks are used in electrical panels and boards within the turbine. They provide the connection point for systems where point-to-point connection between systems is used.
DIN-rail mounted electrical parts are used in many of the electrical cabinets in the turbine. The ABB range of DINrail products includes high performance miniature circuit breakers, miniature circuit reakers, residual current devices, surge protective devices, contactors, pilot devices, timers, and electricity meters. These products are available in a wide range of power ratings and voltages.
