Definitions
- the present invention relates to a breaking device such as a change-over switch for an electrical installation, this device comprising at least two superimposed cut-off blocks, each cut-off block comprising at least two pairs of terminals intended to be connected to at least two phases of said phase installation, at least two pairs of fixed contacts coupled to said terminals and to at least two movable contacts with two stable positions, one closed position in which each movable contact connects the fixed contacts of the same pair to establish the passage of electric current and an open position in which each contact mobile separates said fixed contacts to interrupt the passage of said current electric, the movable contacts being mounted on a common movable bar arranged to move in translation, said apparatus also comprising at least two actuating blocks, each being arranged to move said movable bar of the block corresponding cutoff, and a control block provided with a control shaft can be coupled to a handle and arranged to simultaneously control said actuation blocks.
- a breaking device such as a change-over switch for an electrical installation
- this device comprising at least two superimposed cut
- Such switching devices are generally used for electrical distribution at low voltage single-phase, three-phase or four-phase, the intensity ranging from a few tens to several hundred amps. they ensure the switching, the inversion of source or load swap of two low voltage power circuits as well as their safety sectioning.
- a switching device equivalent to a change-over switch two switches are superimposed in known manner standards placed in the same direction, each consisting of a cut-off block, its actuation block and its control block, which requires having the all parts in duplicate. Then we couple the control handle of the upper switch to the two actuation blocks by extending the shaft of control of said control block by a specific shaft extension, the points connecting rods provided in the actuation blocks being modified on the shaft control.
- the handle can have three stable positions, a middle position "0" and two positions "I", "II” on either side of the middle position, for example at - 65 ° and at + 65 °.
- Reversing switches of this type allow only only two switching combinations: in the first combination, one of the switches is closed when the other is open and, in the middle position, both switches are open. In the second combination, one of the switches is closed when the other is open and, in the middle position, the two switches are closed simultaneously.
- the object of the present invention is to overcome the drawbacks mentioned above by making a breaking device, such as a change-over switch, in which the actuation block and the control block were the subject value analysis and have been optimized to reduce the number of coins and necessary references, facilitate assembly, allow realization simply and at lower cost of a "bypass" type device or a 6 or 8 pole device. Moreover, the optimization of said blocks makes it possible to offer a number of combinations of switching greater than two. As a result, a cutting device is obtained having a best value for money with new features.
