Abstract
An in-line power disconnect assembly for electrical power distribution systems is provided. The in-line power disconnect assembly includes a first end section, a second end section, at least one insulator positioned between the first end section and the second end section, and a switch assembly positioned between the first end section and the second end section. Each of the first and second end sections include a conductor clamp that can be rotated or twisted relative to a longitudinal axis of the first or second end section between a clamping position and an open position.
Claims20
An electrical disconnect assembly comprising:
- a first end section having a first conductor channel and a first conductor clamp that is rotatable between a clamping position and an open position, wherein when the first conductor clamp is in the clamping position a clamp arm of the first conductor clamp is substantially perpendicular to a longitudinal axis of the first end section and a conductor engaging surface of the clamp arm of the first conductor clamp is positioned to engage an electrical conductor within the first conductor channel;
- a second end section having a second conductor channel and a second conductor clamp that is rotatable between a clamping position and an open position, wherein when the second conductor clamp is in the clamping position a clamp arm of the second conductor clamp is substantially perpendicular to a longitudinal axis of the second end section and a conductor engaging surface of the clamp arm of the second conductor clamp is positioned to engage an electrical conductor within the second conductor channel;
- 1
- at least one insulator positioned between the first end section and the second end section;
- and
- a switch assembly positioned between the first end section and the second end section, wherein the first conductor clamp comprises,
- a body having a pivot arm and the clamp arm of the first conductor clamp coupled to the pivot arm, the pivot arm being a substantially cylindrical member at least where the clamp arm of the first conductor clamp couples to the pivot arm, the clamp arm of the first conductor clamp extends from the pivot arm and includes the conductor engaging surface configured to engage the electrical conductor within the first conductor channel, and
- a biasing member coupled to either the pivot arm or the clamp arm of the first conductor clamp and the first side section, the biasing member being configured to normally bias the body of the first conductor clamp to the clamping position.

An electrical disconnect assembly comprising:
- a first end section having a first conductor channel;
- a first conductor clamp attached to the first end section and rotatably movable between a clamping position and an open position, wherein when the first conductor clamp is in the clamping position a clamp arm of the first conductor clamp is aligned with the first conductor channel so that a conductor engaging surface of the clamp arm of the first conductor clamp is positioned to engage a conductor within the first conductor channel;
- a second end section having a second conductor channel;
- a second conductor clamp attached to the second end section and rotatably movable between a clamping position and an open position, wherein when the second conductor clamp is in the clamping position a clamp arm of the second conductor clamp is aligned with the second conductor channel so that a second conductor engaging surface of the clamp arm of the second conductor clamp is positioned to engage a conductor within the second conductor channel;
- an intermediate section between the first end section and the second end section, the intermediate section including at least one insulator having a first end coupled to the first end section and a second end coupled to the second end section, and a switch assembly having a first end coupled to the first end section and a second end coupled to the second end section, wherein the first conductor clamp comprises,
- a body having a pivot arm and the clamp arm of the first conductor clamp coupled to the pivot arm, the pivot arm being a substantially cylindrical member at least where the clamp arm of the first conductor clamp couples to the pivot arm, the clamp arm of the first conductor clamp extends from the pivot arm of the first conductor clamp and includes the conductor engaging surface configured to engage the electrical conductor within the first conductor channel;
- and
- a biasing member coupled to either the pivot arm or the clamp arm of the first conductor clamp and the first side section, the biasing member being configured to normally bias the body of the first conductor clamp to the clamping position.
