Embodiment Construction

[0065] Referring firstly to Figures 1a to 1c, which illustrate in diagrammatic form the principle of the invention, in a highly diagrammatic form, the control device 1 can be seen at different stages during the control cycle, starting from the movable contact for control (Fig. not shown in ) in its closed position and continues until the movable contact returns to the same position after occupying its open position. Figure 1a shows the initial and final positions of the cycle, the illustration cycles in the order 1a, 1b, 1c, 1a and so on.

[0066] The control device 1 is designed to equip an electrical switch, such as a circuit breaker, a disconnector or an earthing device, comprising movable contacts adapted to assume a closed position and an open position. It should be noted that the present invention also provides such a switching device.

[0067] To perform the function of controlling the movable contact, the device 1 firstly comprises an output member 2 , for example in ...

Abstract

The invention relates to a device for controlling an electrical appliance designed to be able to perform the following in succession: during a phase of opening a moving contact, moving the connection end of the moving contact (2a) provided on an output member (2) from point P1 to point P2 under the effect of a mechanical opening spring (12) that sets in motion a moving abutment element (11) which, through butting against it, drives the output member (2); during a phase of resetting the spring, setting the moving element (11) in motion under the effect of a switching-on of a motor (8), keeping the end (2a) at the point P2; and during a phase of closing the moving contact, moving the connection end (2a) from point P2 to point P1, again under the effect of a switching-on of the motor.

Description

technical field [0001] The invention relates to a device for controlling an electrical switch having a movable contact adapted to assume a closed position and an open position. Background technique [0002] Generally, the term "electrical switch" is used herein to refer to a circuit breaker, disconnect switch, or grounding device. It also includes switching devices that combine these different functions, such as disconnector circuit breakers. [0003] In the prior art, we already know that devices of the "combined design" or "hybrid design" type can be realized, since such devices incorporate a system of electric motors and mechanical spring action, which executes the moving contacts for closing and opening the switching device. Closing and opening phases of points. The motor makes it possible, with the aid of a suitable servo control, to control the various tasks of the electrical switch, such as opening and closing its contacts. [0004] Although in a wide range of appl...
