Embodiment Construction

[0055] general layout and main layout

[0056] In an example of the invention, the disconnecting device (1) according to the invention comprises a shaft (2) extending in the x-direction ( figure 1 ). In this example, the x, y and z directions are orthogonal. The shaft (2) is arranged to rotate about an axis of rotation extending in the x-direction. For clarity, some elements of the disconnect device (1) are not in the figure 1 shown in .

[0057] The shaft is threaded. A sliding nut type slide (3) is mounted on the shaft (2) and is also threaded. The thread of the slide block (3) engages with the thread of the shaft rod (2).

[0058] The disconnecting device (1) also comprises a plate-shaped part (4) having a groove (5). The slider (3) protrudes through the slot (5) with a cylindrical protrusion. The protrusion is circular in section perpendicular to the z-direction and has a diameter D. The part (4) is mounted in the recess of the frame (6). The part (4) is mounte...

Abstract

Provided is a disconnection device (1), comprising a contact module (10) with an electrical contact (11), in particular a withdrawable unit for disconnection of the electrical contact. The disconnection device is characterized by a shaft (2) arranged to rotate around a rotation axis and a member (4), wherein the contact module is fastened to the member. The member is arranged to be moveable parallel to a contacting direction for connecting and disconnecting the electrical contact. Furthermore, the member comprises a slot (5) comprising a first edge (51) and a second edge (52) facing the first edge. The angles between the first edge and the rotation axis and the contacting direction and the angles between the second edge and the rotation axis and the contacting direction have values larger than zero. The disconnection device also comprises a slider (3) arranged to be driven in a direction parallel to the rotation axis by the rotation of the shaft, wherein the slider is arranged to engage with at least one of the first edge and the second edge while being driven in the direction parallel to the rotation axis.

Description

technical field [0001] The invention relates to a disconnecting device comprising a contact module with electrical contacts. The disconnecting device can be used to disconnect a low voltage circuit. Background technique [0002] In low voltage switched distribution systems, switching devices are arranged in disconnecting devices. The device is a withdrawable unit in the form of a drawer that can be inserted into a rack located in the housing. The device includes a set of main electrical contacts and a set of auxiliary electrical contacts. Both sets are located on the rear side of the device. The main electrical contacts are used to make contact with the distribution busbar pairs arranged vertically in the rack. Auxiliary electrical contacts are used to make contact with cables of auxiliary circuits. [0003] The device provides multiple connection states, which are selected by a main disconnect switch and by partially or completely withdrawing the device from the rack. ...
