Definitions
- the present invention relates to a circuit breaker self-isolating switch with self-locking in position closed switching chambers, in particular light bulbs empty.
- a self-disconnecting circuit breaker comprising at least one breaking chamber of which opening and closing are actuated by a mechanism actuation and which is fixed to a profile in which is housed a rotary actuating shaft of the driven chamber in rotation by a control device, said profile can rotate around a fixed axis, called the first axis.
- control device is described in the Patent document FR-2 683 939 filed on November 20, 1991.
- the control device is integral with the profile. This profile can rotate to disconnect or plug in the interrupting chamber from or on the busbars, in order to switch to the sectioning position or in the connection position. During this rotation, the breaking chamber and also the control device are tilted into a one-piece assembly.
- the object of the invention is to propose a circuit breaker auto-disconnector which allows self-locking of the tilting to the sectioning position when the switching chamber contacts are in the closed position.
- said control device is fixed, the control device rotates the actuation shaft by via a control rod articulated according to a axis, said second axis, to a connecting rod mounted on the shaft actuation and, in the open position of the contacts of the breaking chamber, said first and second axes are aligned.
- said actuation mechanism comprises said actuation shaft supporting an articulated connecting rod along an axis at one end of an operating rod of which the other end is hinged to one end of a lever deflection pivoting on a fixed axis and actuating the contact mobile of the chamber, said axis being aligned with said second axis.
- said first and second axes are horizontal.
- Figure 1 is a perspective view of a three-phase self-disconnecting circuit breaker conforming to the invention.
- FIGS 2 and 3 are schematic side views of the control device of the invention.
- a three-phase self-disconnecting circuit breaker such as shown in Figure 1, has three chambers cut-off 1, 2, 3, in particular vacuum interrupts.
- a common profile 4 for example metallic and earth potential.
- This profile 4 can rotate along axis 5, preferably horizontal, to ensure the disconnecting function of the device.
- axis 5 is pivoting on a fixed frame 6.
- a rotary shaft 7 for actuating the bedrooms.
- the actuation mechanism includes said shaft actuator 7 supporting, for each chamber 1, 2, 3, a connecting rod 8 articulated along an axis 9 preferably horizontal, at one end of an operating rod 10 of which the other end is hinged to one end of a lever 11 pivoting on a fixed axis 12 and actuating the mobile contact of each chamber 1, 2, 3.
- each room is electrically connected to a first connection jaw 13 and its contact fixed is electrically connected to a second jaw of connection 14. Its jaws 13, 14 come into engagement in busbars, when the device is in the off position sectioned, the busbar 17 associated with the jaws 13 constituting the current supply and the busbar 18 associated with the jaws 14 constituting the current output.
- the self-disconnecting circuit breaker is identical to that described in the previous patent application FR-2 683 939.
- the shaft 4 has a connecting rod additional 8 'whose axis 9' is connected to a rod 15 driven by a control device 16, which therefore drives the shaft 4 in rotation ensuring the opening and closing contacts of the breaking chambers 1, 2, 3.
- the axis 9 ′ is, advantageously, aligned with the axis 9 of the connecting rods 8 of the actuating device.
- FIG. 1 the interrupting chambers 1, 2, 3 are shown in the open position and in the plugged-in position.
- the connecting rod 8 ' is represented. end in closed position of the cutting chambers 1, 2, 3.
- the control device 16 is fixed. The passage of the plugged-in position to the sectioned position and conversely is done by rotation only of the beam 4 and therefore chambers 1, 2, 3 and their device actuation integral with the beam 4.
- FIGS 2 and 3 illustrate this self-locking effect.
- FIG. 2 is a schematic side view of the circuit breaker in the plugged-in position and FIG. 3 is a view analogous in sectioned position.
- the switchgear contacts are in the open position and axes 5 and 9 'are aligned.
- Beam 4 and the bedrooms 1, 2, 3 connected to the latter can then be turned in the direction of the arrow to go from the plugged-in position to the sectioned position shown on Figure 3.
- the levers 8 and 8 'then rotate around their axis 9 and 9 'at the same time as the beam rotates around of axis 5.
