Innovative high-voltage switchgear key to subsea compression

Power EquipmentSubsea Switchgear Electrical System DesignElectromagnetic CompatibilityAuxiliary Power SuppliesProtection SystemInterface EngineeringThermal EngineeringMechanical DesignFabrication EngineeringAvailability StudiesThe pilot subsea gas compressor motor is rated 12.5 MW and is used together with a 400 kW pump. The long tieback makes subsea power distribution necessary. The equipment in the CBM is 36 kV class and the subsea system voltage is 22 kV. Auxiliary power is provided via a transformer and is backed up by an uninterruptible power supply (UPS) in a separate subsea module. Circuit breakers and protection devices that could operate within an oil-filled, pressure-compensated environment are not yet commercially available. The switchgear is in an enclosure that provides a 1-atm pressure environment. Dry nitrogen fills the enclosure. Its physical properties are close enough to air to allow standard electrical equipment to be used. The high-voltage (HV) circuit breakers are proven 36 kV class air-insulated devices. These circuit breakers are also used in arc furnace applications which are characterized by their severe switching duties. The other HV devices used are proven 36 kV class magnetic c...Get price

Switchgear - Wikipedia

High-voltage switchgear was invented at the end of the 19th century for operating motors and other electric machines. The technology has been improved over time and can now be used with voltages up to 1,100 kV. Typically, switchgear in substations are located on both the high- and low-voltage sides of large power transformers. The switchgear on the low-voltage side of the transformers may be located in a building, with medium-voltage circuit breakers for distribution circuits, along withGet price

Design and Installation of Medium Voltage Switchgear (Facts

Distribution Level of A MV SwitchgearStandards For The Design and Installation of MV SwitchgearMedium-Voltage Switchgear DesignIn analogy to distribution grids, switchgear can be assigned to the primary or secondary distribution level: Primary Distribution – What is characteristic for the primary distribution level are high load and short-circuit currents and high-end secondary featuresof the switchgear with regard to protection, measuring, and (remote) control. The switchgear is almost completely equipped with circuit-breakers. They switch large consumers, mostly in industrial plants, or cable rings which feed switchgear at the secondary distribution level. Secondary Distribution – At the secondary distribution level, the switchgear is equipped with switches or a mixture of switches and circuit-breakers, where the proportion of switches clearly dominates. The currents are lower, short-circuit protection is often ensured by the assigned circuit breaker at the primary distribution level. The requirements placed on secondary features are usually lower. Generally speaking, typical forms of substation are:Get price
