Definitions
- the invention relates to a circuit breaker comprising two contacts arranged in a breaking space containing a dielectric gas and between which an electric arc is established during a circuit breaker opening operation, said circuit breaker including a thermal blowing chamber communicating with the breaking space.
- the invention applies to a high voltage circuit breaker intended to cut strong currents by limiting as much as possible the duration of appearance of an arc between its contacts during the opening operation.
- a strong current here denotes a current of high intensity, or else a current which is established for a long time.
- the invention applies in particular to breaking of low frequency alternating currents such as for example the currents flowing in the railway supply networks, for example in Germany and Switzerland, which are supplied at a frequency of 16.66 Hz or 25 Hz. With this type of frequency, the duration of the current is two or three times longer than for a frequency of 50 Hz, so that if an electric arc occurs, the heat produced can be two or three times greater than for a 50 Hz current.
- conventional circuit breakers usually include a pneumatic self-blowing device producing a dielectric gas blowing in the direction of the arc during the opening in order to favor the cutting of this arc.
- a device self-blowing conventionally includes a compression chamber including a piston linked in movement to a movable contact of the circuit breaker and allowing a constant volume of fresh gas to be blown towards the breaking space during each opening. The piston is moved in using the energy of the circuit breaker control which produces the displacement of the moving contact during opening.
- the pneumatic blowing produced must be all the more important as the electric arc has a high intensity.
- One way to increase the blowing for cutting strong arcs intensity consists in adding to the compression blowing chamber pneumatic a thermal blowing chamber.
- the dielectric gas is heated by the electric arc and sees its pressure increase.
- Room is shaped to promote the flow of the gas it contains towards the breaking space in the event of an increase in the pressure of this gas, so that it produces a blowing all the more important as the intensity of the arc is high.
- the temperature can rise too much in the room thermal, which brings down the dielectric strength of the gas which is blown into the breaking space and makes it impossible to cut the current.
- circuit breaker comprising a thermal blowing chamber which communicates part with a cut-off space through the neck of a nozzle and secondly with an expansion space through conduits closed by valves.
- at least one valve is a discharge valve able to open when the pressure in the chamber thermal is above a certain threshold to evacuate the gas under pressure out of the chamber to the expansion space.
- the breaking capacity is improved because if the pressure becomes too high in the thermal chamber, the valve opens to depressurize the room. This depressurization decreases the temperature, which ensures that the gas blown into the cutting space has satisfactory dielectric strength.
- a circuit breaker with respectively pneumatic blowing chambers and is known from patent document EP 0296363.
- the wall of separation between these two chambers is spring mounted, and includes a light which is arranged with another light arranged in the cylindrical envelope which delimits the periphery of the blowing chamber pneumatic, so that these two lights constitute a valve evacuation of overpressure gases from the blowing chamber thermal.
- This partition wall is able to compress the spring if the pressure in the thermal blowing chamber is greater than that in the pneumatic blowing chamber, allowing to place the lights facing each other to let the overpressure gases escape to a space of expansion which surrounds the cylindrical envelope common to the chambers of pneumatic and thermal blowing.
- a circuit breaker architecture in which permanent current contacts would be arranged around the blowing, i.e. in the hot gas expansion space overpressure.
- the gas between the permanent current contacts at moment of separation of the arcing contacts would no longer have properties sufficient dielectrics to prevent arcing between these permanent current contacts, which are not intended to hold a bow.
- An object of the invention is to remedy these drawbacks by proposing a circuit breaker capable of breaking high currents thanks to a system evacuation of hot gases under overpressure, without this requiring too significant modifications to the architecture of a conventional circuit breaker.
- a device is sought which makes it possible not to have to modify that a very limited number of parts on a conventional circuit breaker not provided to support currents with wavelengths / periods too long (or such low frequencies).
- the invention relates to a circuit breaker comprising two contacts arranged in a breaking space which is delimited by a nozzle which contains a dielectric gas, further including a thermal blowing chamber which communicates on the one hand with said cutting space through a neck of said nozzle and on the other hand with a expansion space through a discharge pipe closed by a valve, said valve opening when the pressure in the thermal chamber is greater than a certain threshold for discharging the pressurized gas out of the chamber, characterized in that said discharge duct is produced in said nozzle and defines a shape of revolution in the thickness of the nozzle according to the general shape thereof, to lead into said space expansion downstream of said cutting space with respect to said neck.
- gas blowing through the channel contributes to the blowing of hot gases contained in the diverges from the nozzle and therefore improves the regeneration of the holding dielectric in the breaking space after extinction of the arc.
- this nozzle may also incorporate the valve, so that it could be adapted to an existing circuit breaker in order to reduce the development and manufacturing costs.
- the nozzle is consisting of two coaxial parts, an external part surrounding a part internal so as to leave a free space for revolution forming a conduit evacuation of gases from the thermal chamber, the valve being designed to close said exhaust duct.
- the valve can be manufactured at lower cost.
- the valve and an exhaust duct partner defining a form of revolution reduce losses dump.
- the valve may have a shape annular while being mounted in abutment on one or more calibrated springs for open against the action of these springs. The valve opening threshold can thus be adjusted by simply changing the calibrated spring or springs.
- the circuit breaker includes a piston compression chamber which communicates with the thermal compression chamber.
- the gas blown into the breaking space is a mixture of the gas fresh from the piston compression chamber and gas more hot from the thermal chamber which lowers its temperature to maintain a high breaking capacity of the circuit breaker.
- FIG. 1 schematically shows an example of a circuit breaker according to the invention in axial section.
- This circuit breaker includes a fixed contact 1 forming a rod and a movable contact 2 which is moved in a direction axial AX.
- the movable contact 2 is hollow and is part of a movable assembly including a blowing nozzle 3 of revolution, coaxial with the axis AX, a thermal blowing chamber 4 and a compression chamber by piston 5.
- the moving element also includes a permanent contact 6 which cooperates in closing the circuit breaker with another permanent contact 7 substantially cylindrical which is fixed.
- the blowing nozzle 3 which is made with an insulating material such as Teflon includes a 3 'neck of small section which widens to form a divergent 3 "downstream of this neck.
- contact 1 crosses the neck 3 'of the nozzle 3 and enters the hollow contact 2 located at upstream of the neck along the axis AX, as visible in Figures 1 and 2.
- the neck and the divergence of the nozzle 3 define here the cutting space of an arc electric that stretches between contacts 1 and 2 during the opening of the circuit breaker visible in Figures 3 and 4.
- This breaking space communicates with the thermal blowing chamber 4 via a 4 ′ revolution-shaped duct located between the blowing chamber thermal 4 and the breaking space.
- the thermal blowing chamber 4 defines a coaxial annular space to the axis AX, delimited by the movable contact 2 and by a casing 8 surrounding the movable contact 2, the casing 8 being closed at one of its ends by the blowing nozzle 3.
- the dielectric gas contained in the thermal blowing 4 is put under overpressure by heating on contact of the electric arc which is established between contacts 1 and 2 when the opening. As known from the state of the art, this overpressure produces the thermal blowing of the dielectric gas which moves from the chamber thermal 4 towards the breaking space.
- This blowing chamber thermal 4 communicates with the piston compression chamber 5 at through a plurality of channels 9. When the circuit breaker opens, the gas dielectric contained in the chamber 5 is compressed to flow at through the thermal chamber 4 in the breaking space. Simultaneously with blowing produced by the compression chamber 5, the heating due to the arc electric increases the pressure in the thermal chamber to increase the flow of dielectric gas in the breaking space, as shown more high.
- the thermal chamber 4 communicates through a discharge duct 10 'closed by a valve 10 to an expansion space 15.
- This space expansion is located downstream of the cutting space with respect to the 3 'neck of nozzle, and is partly bounded by the 3 "divergent nozzle.
- the valve opens when the pressure in the thermal chamber 4 is greater than one certain threshold, to evacuate the pressurized gas out of the chamber thermal 4 ..
- the arc electric increases the pressure in the thermal chamber without this pressure does not exceed a predetermined threshold, so that the valve remains closed, as shown in figure 3.
- valve 10 opens to drop the pressure in the thermal chamber, as shown in Figure 4. This drop in pressure is accompanied by a temperature drop, which ensures that the dielectric gas blown into the breaking space has a satisfactory insulating power.
- This valve can for example be mounted at the casing 8 to directly evacuate the gas overpressure to the outside of the thermal blowing chamber 4.
- the valve 10 can be integrated into the blowing nozzle 3 which covers the casing 8.
- the valve 10 here has an annular shape so that it can be mounted in the nozzle 3 on the side of the thermal blowing chamber 4.
- This valve which is made of a rigid material is mounted in a housing 11 of the nozzle defining an annular groove being compressed by one or more calibrated springs 12 which press on the bottom of the groove 11. The valve is thus able to move in translation along the axis AX to open against the action of the springs 12.
- An annular seal 13 seals between the external surface of the valve and the groove.
- This valve is powered by through a plurality of supply conduits 14 made in the nozzle area 3 leading directly to the thermal chamber for have a large opening surface.
- the bottom of the groove 11 communicates with the divergent 3 "by through a discharge duct 10 'located in the thickness of the nozzle.
- This exhaust duct 10 'communicating the housing 11 with the expansion space 15 defines a shape of revolution in the thickness of the nozzle 3 and according to the general shape thereof. It is located in the extension of the valve 10 downstream of its housing 11 so as to be open or closed by the valve.
- the implementation of a valve and a conduit each defining a form of revolution in the nozzle makes it possible to form a flow circuit of large section, that is to say introducing low pressure drops.
- a large flow of gas can be evacuated to drop pressure as quickly as possible and the temperature in the thermal blowing chamber during shutdown high intensity electric arcs.
- This blowing nozzle can be produced by molding and include a cover covering the housing 11 on the side of the thermal blowing chamber while allowing the valve to communicate with this chamber to allow the evacuation of overpressure gas.
- the evacuation duct 10 ′ opens into the divergent 3 "from the nozzle and thus contributes to the regeneration of the gas downstream from the neck nozzle 3 ', which improves the dielectric strength of the gas between the arcing contacts 1 and 2 during the dielectric phase of the breaking.
- the nozzle 3 comprises an internal part 3B and an external part 3A which are coaxial. More specifically, the outer surface of one end of this internal part 3B has on the whole a flared shape. The part of larger diameter of this end is inserted into the casing 8, by example by screwing, and has substantially the shape of an annular flange in which are pierced with the supply conduits 14.
- the external part 3A of the nozzle 3 has a shaped end cylindrical annular with the same external diameter as the annular flange of the internal part 3B, and is inserted into the casing 8 for example by screwing this annular end to bear against the flange ring of the internal part 3B.
- part 3A surrounds all part 3B with the exception of the annular flange of the latter.
- Nozzle 3 can be assembled by mounting the internal part 3B then the external part 3A in the casing 8 before screwing the permanent contact 6 which forms a ring around the casing 8 capable of holding the two nozzle parts 3A and 3B in position relative to the housing 8. After mounting these two nozzle parts, a part of complementary nozzle 3C located in the extension of the internal part 3B at the divergent 3 "can be screwed or even glued on the internal part 3B so as to extend the evacuation channel 10 'towards expansion space 15.
- the compression by piston 5 communicates directly with the thermal blowing 4 through channels 9 provided with non-return valves 9 ′, so that the gases blown into the breaking space are a mixture fresh gas from the piston compression chamber 5 and gas hot from the thermal blowing chamber 4.
- the temperature of the dielectric gas is lowered by the presence of fresh gas, which further increases the breaking capacity of the circuit breaker according to the invention.
- the piston 5 'of the compression chamber 5 can be mounted on a spring.
- the spring is arranged to compress during the movement maneuver when opening the movable contact, so that it releases after displacement of the contact mobile.
