A cyclone separator featuring a cyclone with a lateral calcium carbonate inlet at the top and a calcium oxide outlet at the bottom surrounded by an envelope such that flue gas combustion is kept separate from calcination. To this end, the cyclone is surrounded by lining or by a furnace or gasifier to generate a concentrated current of CO2 that is not mixed with flue gases, thus fulfilling a dual purpose.

The object of this patent is a piece of equipment that generates voltage gaps to test renewable energy generation systems and verify their compliance with grid codes before connecting them to the power distribution or transport system.

The object of this patent is a measurement system for testing power curves and grid quality in wind turbines, as well as power supply quality in general. It comprises a measurement device that conducts the power curve and various power supply quality tests and enables the user to visualize the state of the test being conducted at any given time, where each of the wind turbines presents a measurement device showing the state of the power curve test at any given time and remotely, as well as analysing grid quality in the wind turbine. It also issues reports that can be set up by a user to limit outward data traffic using a communication device.

Design for a retractile modular stator for an electric engine/generator comprising various modules which can be moved radially or in any other direction allowing the separation between the rotor and the stator in the electric machine to be modified. Each module of the stator comprises various windings, cogs, grooves and the corresponding cylinder head section.

The invention presented has the main advantage of managing to reduce the magnetic losses that regularly occur in the ferromagnetic core of electric engines or generators whilst in stand-by mode. It also reduces other losses linked to electric machines such as friction loss and heating loss.

A device to generate electric disruptions in the grid connected to an electric energy generation system such as a wind turbine or solar power plant so as to test the response of the generators to grid disruptions, with the term ‘disruptions’ referring to voltage gaps, power surges, phase jumps and frequency changes. The device comprises one three-phase transformer or three single-phase transformers with variable outlets connected in series between the collection system and the generator. Said transformer is designed to create power surges, voltage gaps and phase jumps through the commutation of a bypass branch with an impedance with the branch containing the transformer, also having a battery of condensers running in parallel to create power surges with the help of serial impedance and/or resistance. It also has a reduction transformer in parallel connected to a rectifier which in turn is connected to resistors to test the response in the event of frequency variations.

A device to verify and test the smooth running of a DC electric battery charger for electric vehicles without the need for an electric vehicle. The device is able to subject the charger to extreme conditions without causing any damage to an electric vehicle. The emulator is fully portable and easy to manage.

The main object of this invention is a system to control the process of recharging electric vehicle batteries, as well as the charging procedure using said system. The system provides a fast, easy and intuitive charging solution for electric vehicle users, as well as enabling smart management and maintenance of the charging system by the infrastructure operators.

A modular inductive charging system for electric vehicles using a charging station equipped with a variety of resonant modules which can be controlled independently, each with their own primary coupling coil, which acts upon electric vehicles that are also equipped with one or more resonant modules. The main advantage that this development entails is providing a multi-function charging station that adapts to vehicles with different types of batteries.

A coil and electric shielding arrangement for a dry-type transformer includes an electric shielding device arranged at a distance from a winding, at an axial end of the winding perpendicular to a longitudinal axis of the transformer, and parallel to a top surface of a coil that is wound around the axis such that the electric shielding device covers a cross-sectional area of the winding perpendicular to the longitudinal axis. An insulation material attached to the winding and to the electric shielding device establishes a first distance between the winding and the electric shielding device along the longitudinal axis such that the winding is shielded against another electric field. The winding and the electric shielding device are casted in a block which insulates the electric shielding device from the electric field of the winding by establishing a second distance between the winding and the electric shielding device.

The present invention relates to the shielding of clamps of a transformer, and in particular to an electric shielding arrangement for a transformer and a transformer with the arrangement. An electric shielding arrangement for a transformer (101) is provided, with a clamp (102, 130, 132) attached at a yoke (109, 124, 126) and stabilizes the yoke (109, 124, 126) of the transformer (101). The arrangement comprises an electric shielding device (100, 140, 142) arranged at the clamp (102, 130, 132) between the yoke (109, 124, 126) and a winding (103) of the transformer (101) and having a trough- like form. The electric shielding device (100, 140, 142) may have the form of a rounded cover and is adapted for shielding the clamp (102, 130, 132) from an electric field of the winding (103).
