Embodiment Construction

[0023] exist figure 1 and figure 2 , it can be seen that the differential switch D mainly includes a terminal 1 at the line end and a terminal 2 at the load end, which are housed in an insulating box, and a shaft 3 supporting the movable contact 4, which is installed so that the movable contact 4 contacts rotate in the box between where the stationary contacts 5 are fixed relative to the box and where these movable contacts 4 are separated from the stationary contacts 5 .

[0024] The unit also comprises operating means C comprising a manually operated handle 6 able to drive the contact support shaft 3 between the two aforementioned positions, said shaft 3 being biased towards the contact 4, by means of a spring (not shown), 5 in the open position.

[0025] It also contains, in a known manner, a differential tripping device capable of opening said contacts in the event of an earth fault.

[0026] The device also comprises a high-speed closing shaft 7 designed to move said ...

Abstract

The device has a sudden closing device including a sudden closing shaft (7) with a lever (13) cooperating with a cam (14) of an operating handle (6) and another lever (15) cooperating with a stop (16). Movable contacts (4) cooperate with fixed contacts (5). Contact pressure springs are placed between the contacts (4) and a contact-holding shaft (3). The springs are compressed at beginning of a closing operation of the handle during retaining of the contacts (4), where energy stored by the springs is released after the operation of the handle to achieve closing of contacts.

Description

technical field [0001] The invention relates to an operating device for an electrical switchgear unit, wherein said electrical switchgear unit is housed in an insulating box and comprises at least one movable contact supported by a contact support shaft, said movable contact being designed as Working together with at least one stationary contact fixed relative to said insulating case; a manually operated handle mounted to rotate about the axis of said insulating case and capable of moving said contacts between an open position and a closed position said contact support shaft between; and a device known as a high-speed closing device comprising a shaft known as a high-speed closing shaft designed to initiate a manual closing operation of said handle with The movable contact is held in the open position by storing energy during a certain operation of the latter, and the movable contact is released after the operation of the handle, so that the previously stored energy makes the ...
