Abstract
Devices, systems, and methods are provided for a high voltage switch. The device can include a first housing, a switch, and a polymer insulating material. The housing can be at ground potential. The switch can be located within the housing and can include a current-breaking component and a moving contact. The current-breaking component can include a fixed contact and an opening contact. The fixed contact can be coupled to a first power lead. The opening contact can be configured to receive a moving contact. The moving contact can be coupled to a second power lead and can be controlled by an actuating mechanism. The polymer insulating material can surround the switch within the housing.
Claims18
A device comprising:
- a first housing, wherein the first housing is at ground potential;
- a switch, wherein the switch is located within the first housing and comprises:
- a current-breaking component with a fixed contact and an opening contact, wherein the fixed contact is coupled to a first power lead and wherein the opening contact is configured to receive a moving contact, and
- the moving contact, wherein the moving contact is coupled to a second power lead and is controlled by an actuating mechanism;
- a polymer insulating material, wherein the polymer insulating material surrounds the switch within the first housing;
- a grounded shield, wherein the grounded shield surrounds at least the current-breaking component;
- and
- an air gap between the polymer insulating material and the grounded shield, wherein the polymer insulating material is coupled to an outer surface of the current-breaking component.
A system comprising:
- a first housing, wherein the first housing is at ground potential;
- a first bushing coupled to a first power lead;
- a second bushing coupled to a second power lead;
- a switch, wherein the switch is located within the first housing and comprises:
- a current-breaking component with a fixed contact and an opening contact, wherein the fixed contact is coupled to the first power lead through the first bushing, and wherein the opening contact is configured to receive a moving contact, and
- the moving contact, wherein the moving contact is coupled to a second power lead through the second bushing and is controlled by an actuating mechanism;
- a polymer insulating material, wherein the polymer insulating material surrounds the switch and the moving contact within the first housing;
- a grounded shield, wherein the grounded shield surrounds at least the current-breaking component;
- and
- an air gap between the polymer insulating material and the grounded shield, wherein the polymer insulating material is coupled to an outer surface of the current-breaking component.
A method, comprising:
- providing a high voltage electrical current through a grounded housing, wherein the grounded housing comprises:
- a first and second power lead coupled to a power supply,
- a switch comprising:
- a current-breaking component with a fixed contact and an opening contact, wherein the fixed contact is coupled to the first power lead and wherein the opening contact is configured to receive a moving contact, and
- the moving contact, wherein the moving contact is coupled to the second power lead and is controlled by an actuating mechanism,
- a polymer insulating material, wherein the polymer insulating material surrounds the switch and the moving contact within the housing;
- a grounded shield, wherein the grounded shield surrounds at least the current-breaking component;
- and
- an air gap between the polymer insulating material and the grounded shield, wherein the polymer insulating material is coupled to an outer surface of the current-breaking component
- determining an overcurrent occurs between the first and second power lead;
- and
- switching off the high voltage electrical current using the switch.
