Definitions
- the present invention relates to high- or medium-voltage arc-blown circuit-breakers using an insulating gas.
- the invention relates more particularly to the insulating nozzles for such circuit breakers.
- An arc blast circuit breaker uses an insulating dielectric gas, such as sulfur hexafluoride, for cutting the electric arc.
- the breaking chamber of these circuit breakers comprises an insulating nozzle which is used to channel the gas, and thus to increase the pressure of insulating gas in the vicinity of the electric arc, which promotes the breaking of the electric arc.
- the nozzle undergoes wear by mechanical abrasion which results from the passage of the gas flow over the surface of the nozzle.
- the nozzle also undergoes wear by pyrolysis resulting from the interaction between the radiation from the electric arc and the material of the nozzle.
- the invention aims to provide an insulating nozzle for a circuit breaker having a combination of advantageous properties from the point of view of the efficiency of the circuit breaker and its service life.
- the material comprises 99.4% by weight of polymer (A) and 0.6% by weight of filler (B).
- the material constituting the nozzle comprises from 92 to 99% by weight of polymer (A) and from 1 to 8% by weight of filler (B).
- the material comprises 98% by weight of polymer (A) and 2% by weight of filler (B)
- the filler (B) has a particle size less than 50 ⁇ m.
- the particle size is less than 1 ⁇ .
- Comparative tests are carried out on nozzles according to the invention and on nozzles according to the state of the art.
- the manufacture of the nozzles is carried out according to known methods.
- a mixture of the composition to be tested is produced by an intimate mixture of fluoropolymer powder and powder of the filler. Then a sketch is made from this composition.
- the blank is produced by isostatic pressing and then baked in the oven.
- the final shape of the nozzle is then obtained by machining the blank.
- the final nozzle is directly obtained by injecting the mixture, previously melted, into a mold.
- Two series of tests are carried out.
- a self-expanding circuit breaker-model is used comprising a chamber filled with insulating gas SF6 in which is placed a cylindrical nozzle formed of the material to be tested and contacts engaged in the nozzle on both sides. other of it.
- the nozzle has an internal diameter of around 20 mm and a thickness of around 10 mm. We establish the arc between the contacts and wait for the break. The following measurements are made.
- the maximum pressure (PMAX5) reached in the chamber at the fifth cut is also measured, in order to check whether the capacity of the material to produce insulating gas remains after several cuts.
- a second series of tests is carried out with an industrial medium-voltage circuit breaker of the puffer type.
- the measurements carried out are then as follows.
- the mixture is composed of TFM polymer and 0.6% by weight of SiO2.
- the results of the tests are as follows:
- the mixture is composed of PTFE and 0.6% by weight of ZnO.
- the results of the tests are as follows:
- the mixture is composed of PTFE and 5% by weight of SiO2.
- the results of the tests are as follows:
- composition contains only the TFM polymer.
- results of the tests are as follows:
- the mixture is composed of PTFE and 20% by weight of CaF2.
- the results of the tests are as follows:
- Example 11 The mixture is composed of PTFE.
- the results of the tests are as follows:
- the mixture is composed of PTFE and 0.3% by weight of MoS2.
- the results of the tests are as follows:
- Examples 9-13 are sometimes better as regards certain properties than those of Examples 1-8 according to the invention, but they are defective for other properties.
- the results of Examples 1-8 in accordance with the invention have the advantage of being satisfactory for all of the properties analyzed.
