Abstract
In various embodiments, a coil spacer includes a first slot section and a second slot section for receiving corresponding coil sections. The coil sections are either radially spaced apart in the case of a disc-shaped spacer or axially spaced apart in the case of a cylindrical spacer, with respect to a central axis. The coil spacer is composed of a hydrophobic thermoplastic. The spacer is configured to inhibit electrical communication between corresponding coil sections. The spacer further includes a plurality of cooling channels configured to guide coolant within a transformer.
Claims20
A transformer comprising:
- an electrically conductive coil defining a central axis, the coil including a first coil section and a second coil section radially spaced apart from the first coil section with respect to the central axis;
- and
- a hydrophobic thermoplastic coil first spacer configured to receive and partially house the electrically conductive coil, the first spacer being configured to inhibit electrical communication between the first coil section and the second coil section.
A transformer comprising:
- an electrically conductive coil defining a central axis, the coil including a first coil section and a second coil section axially spaced apart from the first coil section with respect to the central axis;
- and
- a hydrophobic thermoplastic coil inner spacer configured to receive and partially house the electrically conductive coil, the inner spacer being configured to inhibit electrical communication between the first coil section and the second coil section.
A coil monitoring method comprising:
- providing a hydrophobic thermoplastic first disc that defines a first central aperture that further defines a central axis, the first disc further defining a first slot section and a second slot section, wherein each of the first slot section and second slot section is configured to receive a corresponding coil section from a plurality of coil sections of a coil such that a first coil section of the plurality of coil sections is radially spaced apart from a second coil section with respect to the central axis;
- disposing a hydrophobic thermoplastic second disc that defines a second central aperture that further defines a central axis, the second disc further defining a third slot section and a further slot section, wherein each of the third slot section and the fourth slot section is configured to receive a corresponding coil section from the plurality of coil sections of the coil such that a third coil section of the plurality of coil sections is radially spaced apart from a fourth coil section with respect to the central axis adjacent to the first disc, such that the first disc and second disc combine to define a gap;
- and
- disposing a temperature sensor within the gap.
