Definitions

  • the present invention relates to an electrical switching apparatus.
  • the invention relates in particular to the field of electrical switching devices with separable contacts, such as molded case circuit breakers or switches.
  • Such switching devices with separable contacts comprise a switching mechanism which has the function of moving electrical contacts of the device between an open state and a closed state, for example in response to an action of a trigger or a operator.
  • toggle switching mechanisms also called “tumbler” in English.
  • FR 2 687 249-A1 describes for example a circuit breaker comprising such a toggle switching mechanism.
  • This switching mechanism comprises an articulated toggle, which is connected to a movable contact on the one hand and is driven by a lower connecting rod on the other hand.
  • the lower connecting rod is articulated with an upper connecting rod, itself tiltably mounted on a hook, the hook cooperating with a lock for holding the hook in the locked position.
  • the switching mechanism further comprises a control lever which pivots about a fixed axis and which is connected to one end of a spring, another end of the spring being connected to the axis of the toggle lever by the intermediate of the upper connecting rod.
  • US-4,935,712-A describes such a device according to the preamble of claim 1, which requires the installation of specific parts in the switching mechanism, which is not always achievable without having to design a new mechanism.
  • the invention seeks to remedy more particularly, by proposing a switching device whose contact opening speed is independent of the actuation speed of the control lever.
  • the invention relates to an electrical switching device according to claim 1.
  • the opening speed of the contacts is independent of the speed of the lever.
  • the opening of the contacts begins while the lever is in an intermediate position offset from neutral, where the spring generates sufficient rotational moment on the parts of the switching mechanism to separate the contacts with sufficient speed.
  • the occurrence of electric arcs is limited, and the durability of the electrical contacts and the switching mechanism is extended.
  • FIG. 1 represents an electrical switching device 2, such as a circuit breaker with separable contacts, in particular a molded case circuit breaker.
  • the device 2 can be another type of electrical switching device, such as a switch or a contactor.
  • the switching device 2 comprises a switching mechanism 4, configured to selectively bring into contact or separate a fixed electrical contact 6 and a movable electrical contact 8.
  • the fixed contacts 6 and mobile 8 are thus separable contacts, which are respectively connected to connection terminals of the device 2 and are for example associated with a pole.
  • the device 2 is multipolar and then comprises a pair of separable contacts 6 and 8 per pole.
  • Mechanism 4 is then common to the poles. What is described is true for one pole and can be transposed to other poles, the latter not being described so as not to overload demand.
  • the switching device 2 is intended to be operated manually by means of a control lever 10.
  • the switching device 2 can also include a trigger 12, for example an electronic trigger or an electromechanical trigger.
  • the switching mechanism 4 is represented in a so-called “closing” configuration, in which the movable contact 8 is in contact with the fixed contact 6, thus authorizing the circulation of an electric current. Contacts 6 and 8 are in a state called “closed state”.
  • the switching device 2 comprises a chassis 14, partially shown, on which at least part of the elements of the switching device 2 are mounted.
  • the chassis 14 can be placed inside a housing, not shown, which is made of an electrically insulating material.
  • the fixed contact 6 is fixed relative to the chassis 14, while the movable contact 8 is mounted to pivot relative to the chassis 14 around a main axis X8.
  • the rotational movements of the parts are made around respective axes parallel to the main axis X8, and the translation movements of the parts are made in planes orthogonal to the main axis X8.
  • the axis X8 is perpendicular to the geometric plane of the figures.
  • the movements of the mobile contact 8 are linked to the switching mechanism 4, which here includes a “toggle” type connection 16.
  • This connection is simply called “toggle 16” in the remainder of the description.
  • the toggle 16 comprises a low connecting rod 18 and a high connecting rod 20, which are articulated together at one of their respective ends around an axis X16 of the toggle 16.
  • Axis X16 is parallel to main axis X8.
  • the connecting rod 18 is mounted, at the opposite end of the axis X16, pivoting on the movable contact 8 around an axis X18, which is parallel to the main axis X8.
  • the connecting rod 20 is pivotally mounted relative to the chassis 14 around an axis, not shown, parallel to the main axis X8 and located at the opposite end of the end comprising the axis X16.
  • the high connecting rod 20 is linked to a shaft, called “tree of poles", which serves to synchronize the opening of several switching devices, of the type of switching device 2, connected in parallel.
  • the pole tree is not drawn in the figures.
  • the toggle lever 16 When the mechanism 4 is in the closed configuration, the toggle lever 16 is in a so-called “deployed” configuration, in which the connecting rods 18 and 20 form between them an angle of maximum amplitude, close to 180° but strictly less than 180° , and the separable contacts 6 and 8 are in the closed state.
  • the toggle 16 In the opening configuration shown on the figure 5 , the toggle 16 is completely folded, that is to say that the connecting rods 18 and 20 form between them an angle of minimal but not zero amplitude, and the separable contacts 6 and 8 are said to be “completely open”.
  • the toggle lever 16 is actuated by a lower connecting rod 22, which here has a hook shape.
  • the connecting rod 22 has a first end, pivotally mounted relative to the upper connecting rod 20 around an axis close to the axis X16 and parallel to the axis X16, and a second end which accommodates a rod 24.
  • the rod 24 is here cylindrical and centered on an axis X24 parallel to the main axis X8.
  • the mechanism 4 also includes an upper connecting rod 26 connected to the rod 24.
  • the connecting rod 22 is called lower connecting rod 22 because it is located below the upper connecting rod 26.
  • the qualifiers "high”, “ bottom”, “lower”, “upper” are chosen with reference to the orientation of the switching device 2 in the drawings, and do not prejudge a particular operation of the device 2.
  • the switching device 2 is preferably intended to be mounted so that the top is oriented towards the left of the drawings, as shown by an arrow F1 on the figures 1 to 3 And 5 .
  • the direction of earth's gravity is oriented opposite the arrow F1, that is to say horizontally towards the right of the drawings.
  • the upper connecting rod 26 partially visible in the figures, has in this example a central body in the shape of a triangle, one of the vertices of which has a bearing surface 28.

  • Other structures of switching mechanisms 4 are possible, these structures fulfilling the same functions as the mechanism 4 illustrated .
  • the rocker axis X30 parallel to the main axis X8, is provided in an intermediate part of a hook 34.
  • the hook 34 here has an elongated shape, with a first end mounted to pivot relative to the frame 14 around an axis X34 parallel to the axis X8, and a second end in which a lug 36 is provided.

  • the lock 40 is pivotally mounted relative to the frame 14 around an axis X40, parallel to the axis X8.
  • one end of the lock 40 cooperates with a pawl 42, the pawl 42 preventing clockwise rotational movements of the lock 40 around the axis X40.
  • the pawl 42 is sometimes called a “half-moon lock”.
  • the pawl 42 cooperates with a trigger and allows automatic actuation of the mechanism by the trigger, without manual intervention by an operator.
