It will be apparent to one skilled in the art that embodiments of the present invention may be practiced without some of these specific details.
[0034] The present disclosure relates to the field of low voltage switchgears. More particularly the present disclosure relates to a handle arrangement for the low voltage switchgears.
[0035] The present disclosure elaborates upon a handle arrangement adapted to be configured with an operating shaft of a low voltage switchgear. The handle arrangement includes a handle, having a locking end with one or more flanges in a first direction, configured to rotate between a first position and a second position. The locking end configured to engage with the low voltage switchgear through a push plate. The one or more flanges are engaged with the low voltage switchgear through an opening in the push plate.

[0050] As illustrated, a handle arrangement 100 adapted to be configured with an operating shaft of a low voltage switchgear 200 can include a handle 100. The handle 100 can include a locking end 102-1 with one or more flanges 102-2 in a first direction and the handle 100 can be configured to rotate between a first position and a second position. The handle 100 can be operatively coupled with an operating shaft 202 of the low voltage switchgear. Rotating the handle 100 at the first position can turn the low voltage switchgear to an electrically OFF condition by rotating the operating shaft and the handle 100 at the second position can turn the low voltage switchgear to an electrically ON condition.
[0051] In an embodiment, the locking end 102-2 can be configured to engage with the low voltage switchgear through a push plate 104. The one or more flanges 102-2 can be configured to engaged with the operating shaft of the low voltage switchgear through an opening 104-1 in the push plate 104. The opening 104-2 can be configured to be of similar shape like the locking end with the one or more flanges 102-2. The first direction can be orthogonal to a longitudinal axis of the locking end 102-1. The push plate 104 can be slidable engaged, from a first end, with the one or more flanges 102-1 such that when the push plate 104 is pushed from a second end the push plate 104 can disengage from the one or more flanges 102-2.
[0052] In an embodiment, the one or more flanges 102-2 can align with the opening 104-1 when the handle 100 is in the second position. This can facilitate a clear path for the one or more flanges 102-2 to pass through the opening 104-1 and detaching of the handle 100 from the low voltage switchgear by pulling the handle out of the opening 104-1. A maximum dimension of the one or more flanges 102-2, when aligned with the opening 104-1, can be less than a maximum dimension of the opening 104-1 of the push plate 104 for allowing a clear path to the one or more flanges 102-2 out of the opening 104-1.
[0053] In an embodiment, the one or more flanges 104-2 can misalign, when the handle is in the second position, with the opening 104-1 facilitating an obstructed path for the one or more flanges 102-2 out of the opening 104-1. This can facilitate limiting pulling the handle out of the opening or the handle remains locks with the opening 104-1 even when the push plate 104 is pushed from the second end. The push plate 104 can be elastically configured with the low voltage switchgear through a spring 106 such that once the push plate 104 is pressed from the second end, the push plate is retracted back to its original position. The handle 100 includes a padlock pin 108 which can be slidable configured, along the longitudinal axis, with the locking end 102-1. The padlock pin 108 can be configured to move between a third position and a fourth position.
[0054] In an embodiment, in the fourth position the padlock pin 108 can be configured to slide into a hole, through the opening 104-1 in the push plate 104, in a mount 204 configured with the low voltage switchgears. The movement of the padlock pin 108 can be allowed only when the handle 100 is in the first position i.e. when the low voltage switchgear is in electrically OFF condition. The padlock pin 108 can be operated through an actuator 110 that can be positioned on an upper surface of the handle 100. When the padlock pin 108 is in the fourth position, it can facilitate limiting the rotation of the handle 100 to the second position due the padlock pin obstructing a rotating path, through the opening 104-1, for the locking end 102-1. This can limit any possibility of accidental turning ON the low voltage switchgear when some maintenance person is working on the low voltage switchgear.
[0055] In an embodiment, in the fourth position, the padlock pin 108 can be configured to slide into a hole in a mount 204, configured with the low voltage switchgears. Movement of push plate 104 will be restricted when padlock pin 108 is in fourth position through a feature of push plate 104 located against padlock pin 108 which will always ensure engagement of one or more flanges with push plate 104 and handle 100 will not be disengaged from operating shaft 202 in padlocked condition ensuring safety during maintenance.
[0056] Moreover, in interpreting the specification, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refer to at least one of something selected from the group consisting of A, B, C ….and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
