Definitions
- the present invention relates to an electrical switchgear for medium or high voltage.
- an electrical switchgear for example, a circuit breaker, a disconnector, a contactor, or even a load switch.
- medium or high voltage is meant a voltage greater than about 1000 volts.
- such a switching device comprises a contact assembly, which is provided with two fixed and movable contact members, each of which is equipped with a respective contact element.
- the movable element can thus be moved, relative to the fixed element, between a contact position and a separate cut-off position.
- an electric arc is formed between the two contact elements, which disappears once the arc has been cut off.
- the movable contact member is moreover provided with an insulating nozzle, which delimits an annular channel by which, during the movement of the movable member, an insulating gas, also called cutting gas, is directed towards the zone where produces the electric arc.
- this gas is capable of ensuring a cut-off repeated electrical equipment, namely that the arc breaking is likely to occur several times.
- sulfur hexafluoride SF 6
- carbon tetrafluoride CF 4
- these two gases have good insulating properties, which makes it possible to have electrical equipment in which the parts are placed under tension while being at a short distance from each other.
- they undergo practically no loss of their properties, during the establishment of the arc, so that they do not substantially maintain the latter, then are able to quickly find these properties after the cut of 1 ' bow .
- the two gases mentioned above involve an environmental disadvantage, since they generate a recognized greenhouse effect. In order to remedy this problem, the use of other types of insulating gases has been proposed. So,
- EP-A-0 737 993 and EP-A-1 271 590 mention the possibility of using high pressure nitrogen. Although it is satisfactory in environmental terms, this alternative gas does not however have properties comparable to those of CF 4 or SF 6 .
- the dielectric properties of nitrogen are less good than those of SF 6 or CF 4 . Under these conditions, it is necessary to give a higher pressure to this gas, or else to move away each other the different parts of the apparatus.
- nitrogen is less satisfactory than CF 4 or SF 6 , in terms of cut quality. In fact, when the arc is established, the nitrogen maintains the arc for a longer period than that permitted by the CF 4 or SF 6 .
- the invention aims to propose an electrical switching device which, while using a cutting gas substantially free of CF 4 and SF 6 , has performances, in particular in terms of switching and in dielectric terms, which are close to those of the prior art using the two aforementioned gases.
- an electrical switchgear for medium or high voltage in particular a circuit breaker or a disconnector, comprising a breaking chamber containing a cutting gas substantially free of sulfur hexafluoride (SF 6 ) and tetrafluoride carbon (CF 4 ), this interrupting chamber comprising first and second contact members, each of which is provided with first and second arcing contacts respectively, these two arcing contacts being capable of occupying, in service, a first position in which they are in mutual contact, as well as a second position in which they are separated from each other, the displacement of these two arcing contacts between the first and second positions causing the formation of an electric arc, where provided, in the vicinity of these contacts arcing, at least one irradiation wall capable of being reached by this electric arc, at least two constituents belonging to at least one element from the breaking gas, the first and second arcing contacts, as well as the or each irradiation wall, being capable of decomposing under the effect of the electric arc, so
- this oxide is combined with a fluoropolymer, such as polytetrafluoroethylene (PTFE), as well as with another solid fluoride.
- PTFE polytetrafluoroethylene
- the invention also relates to an electrical switchgear for medium or high voltage, in particular a circuit breaker or disconnector, comprising a breaking chamber containing a cutting gas substantially free of sulfur hexafluoride (SF 6 ) and carbon tetrafluoride (CF 4 ), this interrupting chamber comprising first and second contact members, each of which is provided with first and second arcing contacts respectively, these two arcing contacts being able to occupy, in service , a first position in which they are in mutual contact, as well as a second position in which they are separated from each other, the displacement of these two arcing contacts between the first and second positions causing the formation of 'an electric arc, while it is provided, in the vicinity of these arcing contacts, at least one irradiation wall capable of being reached by this electric
- the subject of the invention is also an electrical switchgear for medium or high voltage, in particular a circuit breaker or a disconnector, comprising a breaking chamber containing a cutting gas substantially free of sulfur hexafluoride (SF 6 ) and carbon tetrafluoride (CF 4 ), this interrupting chamber comprising first and second contact members, each of which is provided with first and second arcing contacts respectively, these two arcing contacts being able to occupy, in service, a first position in which they are in mutual contact, as well as a second position in which they are separated from each other, the displacement of these two arcing contacts between the first and second positions causing the formation of an electric arc, where provided, in the vicinity of these contacts arcing, at least one irradiation wall capable of being reached by this electric arc, at least two constituents belonging to at least one element from the breaking gas, the first and second arcing contacts, as well as the or each irradiation wall, being capable of decomposing under the effect of the electric arc, so
- the mass ratio of the oxide to the solid nitride is between 0.4 and 3, while this oxide and this solid nitride represent, in volume, between 25 and 40%, preferably between 30 and 35%, of the assembly formed by the fluoropolymer, the solid nitride and the oxide.
- nitrogen, nitrogen oxide, argon , carbon dioxide and their mixtures.
- At least two constituents are involved, for the formation of decomposed species which are liable, in turn, to recombine to form at least one new gaseous species.
- These constituents two or more in number, belong to at least one element among the breaking gas, the arcing contacts, as well as the irradiation wall or walls. In other words, these constituents can belong to only one of these elements, or even to at least two of them.
- the constituents mentioned above decompose, so as to form a plasma, within which are present decomposed species in the form of mono or polyatomic chemical species, possibly ionized. These species then recombine, extremely rapidly, according to reactions with both maximum stability and minimal energy requirement.
- the dielectric properties of the gaseous medium located between the electrodes are improved compared to those of the breaking gas.
- the invention guarantees dielectric strength properties after breaking fairly close to those authorized by the solutions of the prior art, using CF 4 or SF 6 .
- the invention is clearly more advantageous than this latter prior art, from an environmental point of view. In fact, thanks to the invention, the filling of the electrical equipment, with a view to its initial commissioning, does not require the use of a gas having a strong greenhouse effect.
- any new gaseous species with a recognized greenhouse effect which would be produced during establishment electric arc according to the decomposition and recomposition reactions mentioned above, are only present in very small quantities.
- gaseous greenhouse species, formed in situ appear only when the arc is established, from a temporal point of view, and only in the vicinity of this arc, from a spatial point of view.
- these fillers have a particle size less than 100 micrometers, that is to say that they are of the micronic or nanometric type.
- the invention clearly differs from a prior art, in which the cutting chamber is provided with a nozzle, intended to channel the cutting gas, which is made of polytetrafluoroethylene (PTFE), or again TEFLON.
- PTFE polytetrafluoroethylene
- the proportions of the various constituents likely to decompose, during the establishment of the electric arc are not suitable for the formation of gaseous species, such as SF 6 or CF 4 , in amounts which make it possible to substantially increase the dielectric properties of the breaking gas.
- the oxide used can be, for example, silicon oxide (Si0 2 ), titanium oxide (Ti0 2 ), aluminum oxide (Al 2 0 3 ) or alternatively phosphorus (P 2 O 5 ).
- This oxide decomposes under the effect of the electric arc, so as to form in particular ions or free atoms of oxygen. The latter are then likely to react with carbon ions, themselves decomposed within the plasma. This leads to the formation of carbon monoxide (s), in particular carbon monoxide or carbon dioxide, which makes it possible to avoid the formation of pure carbon.
- This measure is particularly advantageous, since it makes it possible to overcome a drop in performance of the apparatus, which would be due to the deposition of this carbon. pure on certain organs of this apparatus, such as the pipe nozzle.
- the cut-off gas comprises at least one additional gas, which contains at least one gaseous constituent capable of decomposing, the or each additional gas being a fluorinated gas, in particular Xenon fluoride (XeF 4 ) and / or a carbon dioxide, such as carbon dioxide (C0 2 ) and / or a sulfur gas, such as sulfur dioxide (S0 2 ).

- C0 2 carbon dioxide
- S0 2 sulfur dioxide
- Mention will also be made of the possibility of incorporating sulfur hexafluoride (SF 6 ) and / or carbon tetrafluoride (CF 4 ) into the breaking gas.
