Abstract
An electrical switch gear assembly is provided. The assembly includes two or more insulators, a frame, and a single pivot axis. The two or more insulators are connected to the frame. The frame has a first beam and a second beam with the single pivot axis securing the first and second beams to one another so that the first and second beams can move in a scissors action between a folded state and an unfolded state about the single pivot axis.
Claims22
An electrical switch gear assembly, comprising:
- two or more insulators;
- a frame having a first beam and a second beam, the two or more insulators being connected to the frame;
- and
- a single pivot axis securing the first and second beams to one another so that the first and second beams can move in a scissors action between a folded state and an unfolded state about the single pivot axis.
An electrical switch gear assembly, comprising:
- three tap insulators;
- one central insulator;
- and
- a frame having a first beam and a second beam, the three tap insulators and the one central insulator being connected to the frame, wherein the frame consists of a single pivot axis securing the first and second beams to one another so that the first and second beams can move in a scissors action between a folded state and an unfolded state about the single pivot axis.
A method of installing a switch gear assembly, comprising:
- pivoting first and second beams of a frame with respect to one another about single pivot axis from a folded state to an unfolded state, the frame having, in the unfolded state, portions of the first beam on either side of the second beam with a first tap insulator on one of the portions, a second tap insulator is on another of the portions, a third tap insulator is on the second beam, and a central insulator is on the second beam, and the frame having, in the folded state, a folded angle between the first and second beams of between larger than 0 degrees and less than 70 degrees;
- and
- connecting blades between taps on each of the first, second, and third tap insulators to a corresponding number of taps on the central insulator.
An electrical switch gear assembly, comprising:
- two or more insulators;
- a frame having a first beam and a second beam, the two or more insulators being connected to the frame;
- and
- a single pivot axis securing the first and second beams to one another so that the first and second beams can move in a scissors action between a folded state and an unfolded state about the single pivot axis,
- wherein the frame, in the folded state, has a folded angle between the first and second beams of between larger than 0 degrees and less than 70 degrees.
An electrical switch gear assembly, comprising:
- two or more insulators;
- a frame having a first beam and a second beam, the two or more insulators being connected to the frame;
- and
- a single pivot axis securing the first and second beams to one another so that the first and second beams can move in a scissors action between a folded state and an unfolded state about the single pivot axis, wherein the frame, in the folded state, has a folded angle between the first and second beams of between larger than 0 degrees and less than 70 degrees,
- wherein the frame, in the folded state, has a folded angle between the first and second beams of between 20 and 50 degrees.
