A power transformer is provided with a housing having a plurality of apertures for receipt of a bushing well of a bushing assembly. Each bushing assembly includes a bushing well adapted to be secure in one aperture of the power transformer, and a bushing adapted to be connected to a terminal in the bushing well to permit the conducting of electric current between the bushing assembly and the transformer. The bushing assembly further includes a connector for connecting the bushing conductor to a terminal positioned in the bushing well. The power transformer includes a cap to cover and isolate the unused bushing wells. The cap is preferably a plate structure that attaches to the lip of the bushing well and uses the dielectric formed by the air enclosed by the cap and the bushing well to prevent sparking over to adjacent sites, corona discharge, and accidental contact with a live terminal therein, and to guards against contamination of the bushing well.
A combination of a bushing and a power transformer for operating up to at least 15 kV, the power transformer having a plurality of live bushing wells, each live bushing well having a quick-connect means for unthreadedly receiving a bushing, the bushing and bushing well spaced sufficiently apart and forming a dielectric air gap therein between up to at least 15 kV, the power transformer having a mounting boss on an exterior wall and including insulative material therein, the bushing being removably unthreadedly secured within one of said bushing wells whereby the air gap dielectric combined with the removable unthreadedly secured bushing within the bushing well enables a pullable quick disconnection of the bushing from the bushing well.
A bushing having an outer surface in combination with a power transformer substantially filled with a removable insulating material, the bushing comprising an unthreaded bushing disconnect, the transformer having at least one live unthreaded bushing well having an inside wall, the transformer further having a plurality of like unthreaded bushing wells therein, the live unthreaded bushing well having a first bushing well end and a second bushing well end, the live unthreaded bushing well further having a terminal attached to the second bushing well end of the unthreaded bushing well, the unthreaded bushing disconnect being pullably removably secured to the second bushing well end at the terminal, the unthreaded bushing having a first bushing end and a second bushing end, a coupler having a first coupler end and a second coupler end, the bushing receiving the first coupler end and the unthreaded bushing providing a secure connection to the coupler, the second coupler end having an means for unthreadedly providing a secure connection to the terminal, the body of the bushing being separated from the inside of the bushing well by an air gap whereby a quick-disconnection of the bushing from the bushing well is provided.
A universal bushing in combination with a power transformer, the power transformer comprising a plurality of live bushing wells each bushing well includes a first end and a second end, a terminal includes a proximal end and distal end, the terminal is secured to the second end of the bushing well, the distal end of the terminal is electrically coupled to the power transformer and the proximal end of the terminal extends within the bushing well, the universal bushing includes a first end and a second end and further comprises:
A universal bushing in combination with a power transformer power transformer, the power transformer is adapted to receive a plurality of bushing wells, each bushing well includes a first end and a second end, a terminal includes a first end and a second end, the terminal is secured to the second end of the bushing well, the first end of the terminal is electrically coupled to the power transformer and the second end of the terminal extends within the bushing well, the universal bushing and power transformer comprises:
A universal bushing and power transformer combination, the power transformer containing removable insulative material, and the power transformer comprising at least one universal bushing, the universal bushing and power transformer combination comprises:
A universal bushing in combination with a power transformer, the power transformer having a housing with a plurality of faces, the power transformer comprises a plurality of bushing wells, the bushing wells being live and divided into sets, at least one of said plurality of bushing wells being located on one of said faces and at least another set of said plurality of bushing wells being located on another of said faces, each bushing well including a first end and a second end, a terminal including a first end and a second end, the terminal being secured to the second end of the bushing well, the first end of the terminal being electrically coupled to the power transformer and the second end of the terminal extending within the bushing well, the universal bushing comprising:
