Definitions
- the invention relates to an electrical switch, in particular for the medium or high voltage, comprising a first contact surrounded by a self-blowing interrupting chamber in which gas is put under pressure by thermal effect and a second mobile contact following an axial direction relative to the first contact.
- the bedroom cut off has an internal partition separating a first compartment of a second compartment of smaller volume, both compartments being filled with said pressurized gas and having each a hole for blowing the arc.
- the holes are separated and arranged in series in said axial direction, and the second contact is arranged to release the orifice of the first compartment while it is closing the orifice of the second compartment at the separation of the two contacts.
- the object of the invention is to propose such a switch capable of self-blow off small short-circuit currents (i.e. currents less than or equal to 30% of the breaking capacity of the switch) and the strong currents, with an operating energy the as low as possible.
- the invention relates to such a switch, characterized in that each compartment is connected to its orifice by a blowing channel, in that the first compartment with its blowing channel and its orifice are arranged adjacent to said first contact, in that the second compartment is arranged mainly between the ends of the first arcing contact and of a corresponding permanent current contact, and in that the two compartments communicate with each other via a channel closed by an overpressure discharge device allowing the unidirectional passage of the overpressure gas from the compartment having the smallest volume to the compartment having the greatest volume.
- the larger volume compartment is optimized for cutting the strongest currents, i.e. currents greater than 30% of the switch breaking capacity.
- the weakest compartment volume is optimized to cut the weakest currents. With this arrangement with two thermal volumes, the switch can cut by self-blowing of currents over the entire cut-off range the switch.
- the latter comprises a nozzle made of material insulator arranged coaxially around the first contact and in which penetrates the second contact, at least the second of the two compartments being arranged inside said nozzle, the partition internal separation of these two compartments being formed by a part of the nozzle.
- the channel of blowing of the first compartment is separated from the first arcing contact by a wall surrounding the latter and made of the same material insulating than the nozzle.
- Spacers can be placed in the channel supply air from the second compartment and securely attached to the partition interior separating the two compartments as well as the main body of the nozzle.
- a permanent magnet producing a rotating magnetic field for arc cutting electric is placed inside the nozzle or inside the second contact.
- a self-blowing circuit breaker is partially and schematically shown in axial half section and includes a first arcing contact 1 as well as a current contact permanent 2 corresponding to him.
- Arc contact 1 is coaxially surrounded by a nozzle 3 made of an insulating material electrically, shown in hatched lines.
- This nozzle 3 comprises a fixed V2 volume compartment arranged mainly between the ends of the first arcing contact 1 and of the permanent current contact 2, in which dielectric gas is pressurized by effect thermal.
- Another larger compartment V1 is arranged between the coaxial tubes formed by the first arcing contact 1 and the permanent current contact 2, adjacent to volume V2 and to first arcing contact 1 and on the side opposite to the blowing cone 3 'of the nozzle 3.
- a cut-off chamber with two separate volumes is thus carried out.
- the first compartment below that of larger volume V1, and second compartment that of smaller volume V2.
- These two compartments are separated by an interior partition 4.
- the interior partition 4 is formed by a part of the nozzle 3, formed by the internal tubular wall of said nozzle.
- the second compartment is arranged inside the nozzle, in order to limit the size of the nozzle and therefore its cost.
- a nozzle 3 which extends from the side opposite its blowing cone 3 'to partially or partially surround the entire volume V1.
- the circuit breaker further includes an arcing contact 5 which is movable in the axial direction A with respect to the arcing contact 1 and which penetrates inside the nozzle 3 in the closed position of the circuit breaker.
- the arcing contact 5 is also integral with a current contact corresponding permanent, not illustrated in the figure.
- Arc contact 5 is here in the form of a rod and is inserted into the arcing contact 1 which is hollow.
- Spacers 15 can be arranged in the channel of blowing 13 from the second compartment and fixedly attached to the partition interior 4 as well as the main body of the nozzle 3, in order to increase the mechanical resistance of the nozzle to the overpressure in the second compartment.
- the volume V1 of the first compartment is dimensioned so as to obtain the overpressure necessary to cut down forts currents. This volume V1 must therefore be of sufficient value to avoid the gas it contains does not overheat. Volume V2 is smaller than the volume V1, for example 0.25 to 0.35 times V1, which provides the overpressure necessary to cut the weak short circuit currents.
- the two compartments communicate by a channel 9 closed by a pressure relief device 10 allowing the unidirectional passage of gas from the second compartment having the most small volume V2 to the first compartment with the largest volume V1, in the event of overpressure in the second compartment.
- the device discharge 10 shown in the figure is a calibrated valve.
- the two blowing orifices 6 and 7 are arranged in series according to direction A, the first orifice 6 being located between the arcing contact 1 and the second port 7.
- This arrangement allows blowing along of the electric arc 8 when the circuit breaker opens, on two parts separate from the arch.
- the operation of the device is optimum when the orifice 6 of the larger volume compartment V1 is located adjacent to the contact of arc 1. Indeed, during the separation of contacts 1 and 5, contact 5 first releases the orifice 6 following its removal from the contact 1 in the direction A, which allows the gas in the first compartment to start to blow the arc while the orifice 7 of the second compartment is still closed by contact 5.
- This arrangement allows a rise in rapid gas pressure in the first compartment, and allows limit the volume of gas to be heated by the electric arc to only volume V1 because the calibrated valve 10 then remains closed.
- the overpressure in the second compartment remains weak and the valve 10 therefore remains closed, so that the volume pressurized remains equal to the low value V2.
- the overpressure in the second compartment is limited by the opening of the calibrated valve 10 which allows the passage of a part of the gas from the second compartment in the first compartment. A rapid rise in gas pressure in this first compartment thus provides a quick cut with a short arc length electric. If necessary, a second blowing of the electric arc by the orifice 7 can intervene over a greater length of the arc electric
- the calibrated valve 10 avoids overheating and excessive gas overpressure in the second compartment due to the fact that this gas can be evacuated to the first compartment, its temperature decreasing when it relaxes in volume V1.
- the arc elongation can not be sufficient to obtain a clean cut of the arc by self-blowing.
- the construction of the breaking chamber according to the invention with the two orifices 6 and 7 arranged in series in the direction A allows to obtain a blowing of the gas under pressure directed towards a root of the arc and another blowing of the gas directed towards the other root of the arc. This double blowing is particularly useful to obtain the cutting of faults in line.
- the circuit breaker according to the invention requires operating energy about twice as low as that required for maneuvering a circuit breaker with a single-volume breaking chamber provided a compression piston.
