Abstract
A reinforcement structure for a vacuum interrupter is disclosed. For example, in some implementations, a vacuum interrupter includes a first electrical contact; a second electrical contact; a vessel that encloses the first electrical contact and the second electrical contact in an evacuated space, the vessel including an endcap; and a reinforcement structure at an exterior surface of the endcap, the reinforcement structure including a first side, a second side, and an opening that passes through the reinforcement structure from the first side to the second side. The exterior surface of the endcap includes a recessed region, and at least a portion of the opening is positioned over the recessed region.
Claims20
A vacuum interrupter comprising:
- a first electrical contact;
- a second electrical contact;
- a vessel that encloses the first electrical contact and the second electrical contact in an evacuated space, the vessel comprising an endcap;
- and
- a reinforcement structure at an exterior surface of the endcap, the reinforcement structure comprising a first side, a second side, and an opening that passes through the reinforcement structure from the first side to the second side, wherein the exterior surface of the endcap comprises a recessed region, and at least a portion of the opening is positioned over the recessed region.
A reinforcement structure for an endcap of a vacuum interrupter, the reinforcement structure comprising:
- a body comprising:
- a first side, a second side;
- and at least one opening passing through the body from the first side to the second side, the at least one opening configured to allow fluid to flow between the first side and the second side, wherein
- the first side of the body is configured to be placed in contact with an exterior surface of the endcap of the vacuum interrupter prior to or concurrently with brazing the endcap to a vessel configured to enclose first and second electrical contacts.
A method of assembling a vacuum interrupter, the method comprising:
- providing a vessel body and at least one endcap, the vessel body comprising an insulating material, the at least one endcap comprising a metallic material;
- placing a first side of a reinforcement structure in contact with an exterior surface of the at least one endcap, the reinforcement structure comprising at least one opening that passes from the first side to a second side of the reinforcement structure;
- and
- assembling the vacuum interrupter by brazing the at least one endcap to the vessel body while the reinforcement structure is in contact with the exterior surface of the at least one endcap.
A reinforcement structure for an endcap of a vacuum interrupter, the reinforcement structure comprising:
- a body comprising a first side and a second side, the body comprising:
- a first opening passing through the body from the first side to the second side, the first opening being configured to receive a portion of the endcap;
- at least one other opening passing through the body from the first side to the second side, wherein the reinforcement structure is configured to be mounted to the exterior of the endcap such that the first side of the body faces the exterior surface of the endcap, the second side of the body faces away from the endcap, and the at least one other opening is configured to fluidly couple a region between the first side and the exterior surface of the endcap to a region at the second side.
