Submersible, high-voltage electrical connector

A submersible, high-voltage electrical connector comprising:

• a female connector having an interior chamber and a conduit configured to connect the interior chamber to an evacuation pump;
• and
• a male connector configured to fit within the chamber of the female connector, the conduit of the female connector further configured to, when the male connector and the female connector are mated, substantially evacuate any liquid from the chamber of the female connector,
• the female connector further comprising a rotary brush configured to remove debris from the male connector as the male connector is mated to the female connector, in which the rotary brush is powered by impulse turbine buckets that are powered by one or more water jets.

A submersible, high-voltage electrical connector comprising:

• a female connector having an interior chamber and a conduit configured to connect the interior chamber to an evacuation pump;
• and
• a male connector configured to fit within the chamber of the female connector, the conduit of the female connector further configured to, when the male connector and the female connector are mated, substantially evacuate any liquid from the chamber of the female connector,
• the female connector further comprising an electrical terminal configured to:
• substantially encircle the male connector when the male connector is mated to the female connector,
• increase in circumference in a first configuration to reduce contact pressure between the electrical terminal and the male connector during mating and decoupling of the male connector and the female connector, and
• reduce in circumference in a second configuration to increase contact pressure between the electrical terminal and the male connector when the male connector and the female connector are mated, and
• the electrical terminal including an inflatable actuator configured to expand to transition the electrical terminal from the second configuration to the first configuration.

A pump-turbine, motor-generator assembly comprising:

• a pump-turbine configured to operate as a pump when fluid passes through the pump-turbine in a first direction and as a turbine when fluid passes through the pump-turbine in a second direction, opposite to the first direction;
• a motor-generator configured to operate as a motor to drive the pump-turbine when fluid passes through the pump-turbine in the first direction and as a generator of electrical power when fluid passes through the pump-turbine in the second direction;
• and
• a submersible, electrical connector configured to convey electrical power between the motor-generator and an electrical junction that is external to the pump-turbine, motor-generator assembly, the electrical connector comprising:
• a female connector having an interior chamber and a conduit configured to connect the interior chamber to an evacuation pump, and
• a male connector configured to fit within the chamber of the female connector, the conduit of the female connector further configured to, when the male connector and the female connector are mated, substantially evacuate any liquid from the chamber of the female connector,
• in which the female connector further comprises a rotary brush powered by impulse turbine buckets and configured to remove debris from the male connector as the male connector is mated to the female connector.

A pump-turbine, motor-generator assembly comprising:

• a pump-turbine configured to operate as a pump when fluid passes through the pump-turbine in a first direction and as a turbine when fluid passes through the pump-turbine in a second direction, opposite to the first direction;
• a motor-generator configured to operate as a motor to drive the pump-turbine when fluid passes through the pump-turbine in the first direction and as a generator of electrical power when fluid passes through the pump-turbine in the second direction;
• and
• a submersible, electrical connector configured to convey electrical power between the motor-generator and an electrical junction that is external to the pump-turbine, motor-generator assembly, the electrical connector comprising:
• a female connector having an interior chamber and a conduit configured to connect the interior chamber to an evacuation pump, and
• a male connector configured to fit within the chamber of the female connector, the conduit of the female connector further configured to, when the male connector and the female connector are mated, substantially evacuate any liquid from the chamber of the female connector,
• in which the male connector is mounted to a fixed surface through at least three bridge-bearing supports, the bridge-bearing supports each comprising alternating layers of metal disks and elastomeric disks.
