| 摘要 |
The invention relates to a control and supply system for electrical devices, comprising at least one voltage supply and control device above sea level, a subsea cable connecting said voltage supply and control device with the electrical devices, and a control and actuating device which is associated essentially in situ with the electrical devices. The aim of the invention is to improve one such control and supply system in such a way that supplies are possible over larger distances, using fewer means, obtaining higher efficiency and making better use of the system. In order to achieve this, the voltage supply and control device comprises at least one AC/DC converter for producing a direct voltage in order to feed the subsea cable, the control and actuating device is associated with at least one DC/DC or DC/AC converter for converting the direct voltage transmitted by the sub-sea cable into a direct voltage or an alternating voltage, and the voltage generated thereby can be transmitted to the electrical device via the connecting line.
