- the invention relates to a protection device for an electric circuit, and an electrical circuit equipped with such a protective device. Finally, the invention relates to a method for protecting such an electrical circuit.
- an electrical protection device or component capable of opening the electric circuit when the latter is traversed by an electrical fault current, such as a current of overload or short circuit current.
- a fuse is a dipole that uses the Joule effect of the electric current flowing through it to, in case of overcurrent, melt an electrical conductor that opens the electrical circuit and thus prevents the electric current from circulating.
- the fuses are sized according to the intensity of the fault current that the system must protect, as well as its opening time.
- Pyrotechnic circuit breakers also known as “pyroelectric switches” or “pyroswitches” in the English language, are also known.
- a limitation of pyrotechnic circuit breakers is today their low ability to cut high voltages, for example greater than 50V. Indeed, when cutting under high voltage, there is an arcing that can cause the explosion of the device.
- the pyrotechnic circuit breakers are often bulky.

- the pyrotechnic circuit breaker is less resistive than the fuse, the majority of the electric current will flow in the pyrotechnic circuit breaker.
- the pyrotechnic circuit breaker opens.
- the fuse is still closed at this stage, it bypasses the pyrotechnic circuit breaker, avoiding the appearance of an electric arc within the latter.
- the current then flows into the fuse, melting it.
- Such a protection device can be used with high voltages that are greater than the limit voltage of the pyrotechnic circuit breaker, up to a voltage level equivalent to the fuse rating. As the fuse only sees weak currents in use nominal, its dimensioning can be reduced, which reduces its cost and its cut-off time.
- the pyrotechnic circuit breaker requires a control circuit able to provide the cutoff control.
- a control circuit can be complex and include, for example, a current sensor, a data processing unit and a microcontroller.
- the control circuit needs to be powered by an external power source.
- the hybrid protection device consisting of the fuse, the pyroelectric switch and its control circuit, is not autonomous and, despite lower costs for the fuse, such a device generates a higher cost and bulk, especially in because of the external power source.

- the control circuit is responsible for generating and transmitting the trigger signal to the pyroelectric switch.
- the protection device has a low production cost and a small footprint because it does not require any external power source for triggering the pyroelectric switch. The protection device thus allows the recovery of the electrical energy generated by the fusion of the second fuse. In addition, the protection device according to the invention induces very low power losses and improved cutoff performance.
- such a protection device comprises one or more of the following characteristics, taken in any technically permissible combination:
- the breaking current of the second fuse is equal to a nominal value of electric current, this nominal current value being defined as being the maximum value of the current intended to flow in the protection device during normal operation, and the breaking voltage of the first fuse is equal to a nominal voltage value, this rated voltage value being defined as the maximum value of the voltage intended to be applied across the protection device during normal operation.
- the power zone of the pyroelectric switch has a much lower electrical resistance than the first fuse.
- the breaking current of the first fuse is at least four times less than or equal to the nominal value of electric current, and the cutoff voltage of the second fuse is at least four times less than or equal to the nominal voltage value.
- the device is configured to be successively in a closed configuration where the first and second fuses are not fused, a first intermediate configuration where the second fuse is melted and the supply voltage is supplied to the control circuit; second intermediate configuration where the pyroelectric switch is tripped and the first fuse is not fused, and an opening configuration where and the first and second fuses are melted.
- the device comprises at least two pyroelectric switches connected in parallel to the first fuse between the first conductor and the second conductor.

Because of the electric current, and within a range of predetermined time by the gauge of the second fuse 10, the second fuse 10 begins to melt and the electric arc A is installed across the second fuse 10. As mentioned above, the second fuse 10 is dimensioned so that the electric arc A remains present between its terminals while it is melting, as long as the current I is present, this which generates the supply voltage V and ensures the passage of the current.

During step b), the method comprises transmitting, with the control circuit 14, the signal tripping S at the pyroelectric switch 12.
