摘要： A power-transmission cable protection-and-control arrangement for a capacitive power-transmission cable comprises,
at one end termination of the cable a load or supply terminal for a load or supply cable, a pair of cable terminals for a pair of conductors of the capacitive power-transmission cable, the conductors being connected directly or via extension conductors to the terminals in use, one of the pair of cable terminals being connected by a rail or busbar to the load or supply terminal, an electromagnetic or electronic switch between the rail or busbar and the other of the pair of cable terminals and
at the one end or at another end termination of the cable means for measuring the differential voltage between the pair of cable terminals, i.e. between the capacitive cable conductors in use, and means for controlling the switch to close in the event that the differential voltage exceeds a threshold below dielectric breakdown of the capacitive cable.
An associated power supply network comprises a power source, connected to a first node, connected by two or more conductors separated by a dielectric to a second node, and a control system
wherein the two or more conductors are capable of transmitting power between the first and second nodes in a first mode being via a galvanic connection or in a second mode as a capacitive cable,
wherein the control system is capable of switching the two or more conductors between the first and second modes, and
wherein the control system can be the cable protection-and-control arrangement.

摘要： A protection circuit (20) comprising an inrush current detector operable to detect an inrush current from a DC link. The inrush current detector comprises a transistor switch (Q1) that is turned on in normal operation of the protection circuit. The protection circuit operates to detect when the voltage across the transistor switch (Q1) exceeds a threshold voltage in response to a detected inrush current, and in response operates to turn off the transistor switch.

摘要： A DC-link capacitor protection circuit (40) is described having a resistive divider (26, 28) connected in parallel with a series connection of DC link capacitors (22, 24). The mid-points of the DC link capacitors (22, 24) and the resistive divider (26, 28) should have the same voltage, but those voltages will differ in the event of a DC-link capacitor fault (such as a short circuit). The circuit (40) includes a diode bridge (D1-D4) that provides an output (e.g. using an optocoupler (IC1)) when the mid-point voltages differ by more than a defined amount. In response to that output from the diode bridge (D1-D4), an input stage for charging the DC link capacitors is deactivated.
