Definitions
- the present invention relates to a pressurized dielectric gas circuit breaker, of the type comprising a blowing chamber and a thermal volume.
- the blowing chamber comprises means such as a cylinder and piston for compressing the gas at the time of the opening operation and directing it, through a blowing nozzle on the arc to be cut.
- Thermal volume is meant a volume opening to an area close to that where the arc shape at the time of r breaker opening.
- the gas of this volume is heated by the arc and its pressure increases.
- the energy thus accumulated is generally used to contribute to the blowing of the arc and / or constitute an additional energy for the operation of the circuit breaker.
- the arc In the case where the current to be cut is low (nominal current or lower), the arc is low and the thermal volume plays a negligible role in breaking the arc which must then be ensured by the blowing chamber.
- the gas heated by the arc is sent directly to the arc to be cut.
- this gas does not have all the dielectric qualities required for perfect arc cutting, due to the impurities it contains and the ionization of some of its molecules.
- An object of the invention is to use the energy of the arc to send a jet of fresh gas onto the arc and not a hot and polluted gas.
- An object of the invention is to push fresh gas without mechanical means.
- the circuit breaker includes an insulating jacket. 1 and contains a dielectric gas such as sulfur hexafluoride under a pressure of a few bars.
- the breaking chamber includes a fixed assembly and a set mobile.
- the fixed assembly comprises a metal block 2 connected to a power outlet not shown; on the block 2 is fixed a part 3 comprising a tubular part 3A at the end of which is arranged a ring 4 constituting the fixed main contact of the circuit breaker.
- a cylindrical piece 6 in the thickness of which are formed channels such as 7 which pass through it parallel to its axis.
- the annular volume between the cylinders 6 and 3A is designated by 8.
- the channels 7 communicate with the volume 8 by an annular volume 9 formed between the parts 3 and 6.
- a tubular part 14 At the end of the tube 6, and on the interior side, is fixed a tubular part 14 to which is subjected a ring of arcing contact fingers 15.
- an insulating tip 16 terminated by an annular electrode 17 with floating potential.
- the fixed main contact is extended by an insulating nozzle 19 defining with the insulating nozzle 16 a passage 20.
- the passage 20 communicates with the passage 8 by means of a movable valve 21, coming into contact under the action of a spring 22 with a step 6A of the tube 6.
- the passage 20 also communicates, by a passage 24, with a blowing volume 25 delimited by an insulating cylinder 26, a semi-mobile piston 27 and a crown 3B forming part of the part 3.
- the piston moves under the action of a spring 28 placed in a tubular housing 29.
- the piston is extended by a guide cylinder 30.
- a ring 33 guides the cylinder 30.
- References 34 and 35 designate pressure balancing holes.
- the insulating part 16 and the fingers 15 define a volume thermal 36 opening onto the area where an arc forms when the circuit breaker opens.
- the thermal volume 36 is closed by the tubular end part of the movable part 40 constituting the movable arcing contact.
- the thermal volume 36 remains closed by means of a socket 37 pushed by a spring 38.
- the socket 37 has an end 37A of insulating material.
- the tube 40 constituting the movable arcing contact is terminated by a tip 40A of alloy resistant to wear due to the arcing.
- the movable part of the switching chamber carries a set of permanent contact fingers 41, cooperating with contact 4.
- the fingers 41 are protected by a scent-proof cover 42 also serving as a pusher for the tube 26.
- the mobile assembly is connected by sliding contacts not shown to an outlet not shown.
- the circuit breaker works as follows.
- FIG. 3A Reference is made to FIG. 3A.
- the arc A1 which gushes out, during the separation of the arcing contacts, between the fingers 15 and the electrode 17, produces in the thermal chamber 36 an increase in pressure insufficient to move the valve 21.
- Arc A2 which is established between electrode 17 and movable arc contact 40 is cut off by the jet of compressed gas coming from blowing volume 25 and which passes through passage 20.
- FIG. 3B Reference is made to FIG. 3B.
- the pressure generated by the arc A1 is so high that it succeeds in overcome the pressure of the spring 22 and the back pressure of the volume 25.
- the valve 21 opens under the action of the gas contained in the channels 8 and which are pushed by the pressure generated in the volume 36.
- the gas of the channels 8 is fresh thanks to the volume of gas 7 which isolates the gas from the channels of the thermal chamber 36.
- the gas from the channels 8 flows through the blowing nozzle 20 and comes to cut the arc A2.
- the fresh compressed gas in volume 25 can then escape through passages 24 and 20, and ensure the dielectric strength of the device.
- the invention thus makes it possible to use the thermal energy of the arc under the best conditions.
- the invention applies to high voltage circuit breakers.
