Embodiment Construction

[0023] in figure 1 with figure 2 In, it can be seen that the differential switch D mainly includes the wiring terminal 1 on the line end and the wiring terminal 2 on the load side installed in the insulating box, the shaft 3 supporting the movable contact 4, and the shaft is installed in the movable contact 4 The contact is rotated in the box between the position of the stationary contact 5 fixed with respect to the box and the position where the movable contacts 4 are separated from the stationary contact 5.

[0024] The unit also includes an operating device C, which includes a manual operating handle 6 capable of driving the contact support shaft 3 between the two above-mentioned positions, the shaft 3 being biased toward the contact 4, by a spring (not shown), 5's open position.

[0025] It also contains, in a known manner, a differential trip device capable of opening the contact when a ground fault occurs.

[0026] The device also includes a high-speed closing shaft 7, whi...

Abstract

The invention relates to an operating equipment of an electric switch device cell which comprises a manual operating handle (6) of a movable contact terminal (4) and a shaft which is called a high-speed close shaft (6). The operating equipment is characterized in that the high-speed close shaft (7) comprises a first rod (13) which runs together with a cam (14) forming the handle (6), at least onesecond rod (15) which runs together with at least one retainer (16) respectively; each retainer is firmly fixed on the movable contact terminal; therefore, when starting to be closed by handle, the movable contact terminal is fixed and the cam (14) enforces force on the first rod (13). When the handle (6) runs in the above way, the second rod (15) on the movable contact terminal (4) is opened, and the opening action leads to the high-speed close of the contact terminals (4, 5).

Description

Technical field [0001] The present invention relates to an operating device of an electric switchgear unit, wherein the electric switchgear unit is installed in an insulating box and contains at least one movable contact supported by a contact support shaft, and the movable contact is designed as Together with at least one stationary contact fixed relative to the insulating box; a manual operating handle installed to rotate around the axis of the insulating box and capable of moving between the open position and the closed position of the contact Between the contact support shaft; and a device called a high-speed closing device, the device includes a shaft called a high-speed closing shaft, the high-speed closing shaft is designed to start the manual closing operation of the handle and After a certain period of operation of the latter, the movable contact is maintained in the open position by energy storage, and the movable contact is released after the operation of the handle, so...
