ELECTRICAL DEVICE OF CIRCUIT BREAKER TYPE
The present invention relates to an electrical device of circuit breaker type. Electrical devices of this type serve to protect electrical equipment against over currents and short circuits.
There are electric devices of a circuit breaker type comprising a housing, a first circuit having a first contact and a second circuit being mounted in parallel with the first circuit and having a second contact and a bimetallic strip.
Said first circuit and said second circuit are connected in series with a coil of a magnetic actuator. Said first contact comprises a first contact element and a second contact element and said second contact comprises a third contact is element and a fourth contact element. Said magnetic actuator is able to open the first contact by separating the first contact element from the second contact element when a first current is applied to the coil and is able to open the second contact by separating the third contact element from the fourth contact element when a second current is applied to the coil, the value of the second current being greater than the value of the first current. Such an electrical device is, for example, known from WO 2012/140145 Al.
This type of electrical device allows, due to the first circuit and the second circuit being connected in parallel, a reduction in its overall impedance.
When an overload occurs in an electrical installation to which the electrical device is connected, said first current is applied to the coil. Following this application of the first current, the magnetic actuator opens the first contact by separating the first contact element from the second contact element.
Thus, the first circuit is interrupted, and the overload traversed by the electrical installation, passing entirely through the second circuit. The overload can thus deform the bimetallic strip. The bimetallic strip, which can be mechanically connected to the second contact via a cut-off lock, can therefore trigger the opening of the second contact by separating the third contact element from the fourth contact element. The circuit traversed by the overload is thus interrupted. In the case of a short circuit, the short circuit current flows through the first circuit and the second circuit and a first current is applied to the coil. Then, the magnetic actuator opens the first contact by separating the first contact element from the second contact element. After a delay of approximately 0.5 to 1.5 ms, the short-circuit current passes through the second circuit and the short-circuit current is applied to the coil, the value of the short-circuit current being greater than the value of the second current, is Then, the magnetic actuator opens the second contact by separating the third contact element from the fourth contact element.
In the document WO 2012/140145 Al, the first contact element, as well as the second contact element, are each pivotally mounted relative to the housing and are each provided with a spring to which they are respectively connected. Each of these springs applies a force to the contact element to which they are connected. The first and third contact elements are respectively held against the second contact element and the third contact element. A third spring is connected to the mechanical lock and applies a force to the mechanical lock for opening the first contact and the second contact. The first spring therefore acts in a direction opposite to the direction in which the third spring acts. This makes the circuit breaker mechanism unstable and susceptible to malfunction.
The purpose of the electrical device according to the invention is to overcome these drawbacks and to provide an electrical device having a stable and reliable mechanism, while ensuring satisfactory breaking performance.
For this purpose, the electrical device according to the invention is an electrical device of the type circuit breaker or contactor, comprising a housing, a first circuit comprising a first contact and a second circuit connected in parallel with the first circuit and comprising a second contact and a bimetallic strip. Said first circuit and said second circuit are connected in series with a coil of a magnetic actuator. Said first contact comprises a first contact element and a second contact element. Said second contact comprises a third contact element and a fourth contact element. Said magnetic actuator is able to open the first contact by separating the first contact element from the second contact element when a first current is applied to the coil and is able is to open the second contact by separating the third contact element from the fourth element contact when a second current is applied to the coil. The electrical device according to the invention is characterised in that it comprises a contact carrier comprising a first mechanical link mechanically connecting the first contact element to the contact carrier, a second mechanical link mechanically connecting the third contact element to the contact carrier and a third mechanical link mechanically connecting the contact carrier to the housing, the contact carrier allowing the relative movement of the first contact element and the third contact element relative to the housing.
The electrical device according to the invention has the advantage of having satisfactory breaking performance and of having a stable and reliable mechanism.
According to an additional possible feature, the magnetic actuator may be a double-stage actuator and comprise at least two stages, that is to say a first stage and a second stage.
According to one possibility, the first stage of said magnetic actuator can be adapted to open the first contact by separating the first contact element from the second contact element when the first current is applied to the coil and/or the second stage of said magnetic actuator can be adapted to open the second contact by separating the third contact element from the fourth contact element when the second current is applied to the coil.

Thus, the forces applied by the first spring and the second spring, respectively to the first contact element and the third contact element, are independent of the orientation (angular position) of the contact carrier relative to the housing. As a result, the force applied by the first spring and the second spring can be precisely predetermined, which has the effect of improving the breaking performance.
According to one possibility, the first mechanical link and/or the second mechanical link and/or the third mechanical link is (are) a mechanical link(s) with one degree of freedom.

In the context of this first variant, according to possible additional features, the first axis, the second axis and the third axis are substantially parallel.
In this same first variant, according to one possibility, the first axis and the second axis are substantially collinear.
In the context of a second variant of the electrical device, according to one is possibility, the first mechanical link allows movement of the first contact element with respect to the contact-carrier along a fourth axis and/or the second mechanical link allows movement of the third contact element relative to the contact carrier along a fifth axis and/or the third mechanical link allows movement of the contact carrier relative to the housing along a sixth axis.

Thus, the breaking performance and the reliability of the mechanism of the electrical device are improved.
According to one possibility, the first current has an intensity greater than
1.13 times a rated current of the electrical device, preferably between 1.13 and 2.55 times the rated current of the electrical device, more preferably around 1.45 times the rated current of the electrical device and/or the second current has an intensity between 2.55 and 20 times the rated current of the electrical device, preferably between 4 and 12 times the rated current of the electrical device.
