(WO2015197140) Claims   1.  A subsea switchgear for switching the power supply to plural subsea loads (40), comprising a subsea enclosure (11) configured to allow the deploy.not. ment of the subsea switchgear (10) at a subsea location, a power input (12) for receiving AC electrical power from a power source (50),    - at least two power outputs (13) for giving out AC elec.not. trical power, and    a power distribution bus (15) for distributing the received AC electrical power to the at least two power outputs (13) , wherein between each power output (13) and the power distribution bus (15), a contactor (20) is connected which is con.not. trollable to connect or disconnect the respective power out.not. put (13) from the power distribution bus (15) .   2. The subsea switchgear according to claim 1, wherein the contactor (20) is submerged in a dielectric liquid.   3. The subsea switchgear according to any of the preceding claims, wherein the contactor (20) is a solenoid contactor.   4. The subsea switchgear according to any of the preceding claims, wherein the subsea switchgear (10) provides power distribution for three phase AC electric power, wherein the power input (12) is a three phase power input, wherein each power output (13) is a three phase power output, and wherein two or three contactors (20) are provided for each power out.not. put (13) to allow connection or disconnection of two or three phases, respectively, of said power output (13).   5. The subsea switchgear according to any of the preceding claims, wherein the contactors (20) are located in a chamber    (35) filled with dielectric liquid, in particular with an es.not. ter-based dielectric liquid or an oil.   6. The subsea switchgear according to any of the preceding claims, wherein the subsea switchgear (10) comprises for each power output (13) a chamber (35) in which the contactor (20) for the power output (13) is arranged and which is filled with dielectric liquid, in particular with an ester-based di.not. electric liquid or an oil.   7. The subsea switchgear according to claim 5 or 6, wherein the chamber (35) is provided by an intermediate enclosure (30) located at least partly inside the subsea enclosure (11) .   8. The subsea switchgear according to claim 7, wherein the intermediate enclosure (30) comprises a flexible portion (32), in particular a liquid tight or liquid permeable mem.not. brane, which provides pressure compensation between the in- side of the intermediate enclosure (30) and the inside of the subsea enclosure (11).   9. The subsea switchgear according to any of claims 6 to 8, wherein the chamber (35) comprises the contactors (20) for all phases of the respective power output (13) .   10. The subsea switchgear according to any of the preceding claims, wherein the subsea enclosure (11) comprises an output penetrator and/or an output connector (16) for each power output (13) .   11. The subsea switchgear according to any of the preceding claims, wherein the subsea enclosure (11) comprises an input penetrator and/or an input connector (14) for the power input (12) .   12. The subsea switchgear according to any of the preceding claims, wherein the subsea switchgear (10) is adapted to dis-   tribute AC electric power at a voltage level within the range of about 500 V to about 10,000 V, in particular of about 1,000 V to about 7,000 V. 13.  The subsea switchgear according to any of the preceding claims, wherein the contactor (20) is a no-load contactor adapted to be operated only when the power supply to the sub.not. sea switchgear (10) is disconnected. 14.  The subsea switchgear according to any of the preceding claims, wherein the subsea switchgear (10) is configured to directly supply the AC electrical power received at the power input (12) to the respective power output (13) without any conversion .   15. The subsea switchgear according to any of the preceding claims, wherein the subsea switchgear (10) does not comprise a power conversion device such as a transformer or a frequency converter or a variable frequency drive.   16. The subsea switchgear according to any of the preceding claims, wherein the subsea switchgear (10) comprises a con.not. trol unit adapted to control the switching state of the con.not. tactors (20) .   17. The subsea switchgear according to claim 16, wherein the control unit is configured to have a mode of operation in which it controls the contactors (20) so as to connect the power input (12) subsequently to a different power output (13) for a predetermined amount of time, while the remaining power outputs (13) are disconnected from the power input (12) .   18. A pipeline heating system comprising a subsea switchgear (10) according to any of the preceding claims, an further comprising plural heating units, each for heating a pipeline section, wherein a heating unit is connected to each power output (13) of the subsea switchgear (10) .    19. A subsea power distribution system for distributing electrical power to plural subsea loads (40), the subsea loads (40) comprising electric motors, wherein the subsea power distribution system comprises a subsea switchgear (10) according to any of claims 1-17.   20.  A method of operating a subsea switchgear (10), compris.not. ing the steps of receiving AC electrical power at a power input (12), distributing AC electrical power to two or more power outputs (13) by means of a power distribution bus (15), and    - switching the power supply to the power outputs (13) by means of a contactor (20) connected between the respec.not. tive power output (13) and the power distribution bus (15) .
