Definitions
- the present invention relates to a circuit breaker with high voltage self-blowing arc.
- circuit breaker is described for example in the European patent application no. 0 475 270.
- the circuit breaker includes, for each phase, a insulating jacket filled with gas with good properties dielectrics, such as sulfur hexafluoride SF6, under a pressure of a few thousand hectopascals.
- gas with good properties dielectrics such as sulfur hexafluoride SF6, under a pressure of a few thousand hectopascals.
- a mobile assembly actuated by a control, and comprising movable main contacts and arcing contacts; the mobile assembly includes two communicating volumes, one called compression volume, cooperating with one fixed piston and the other, said volume of blowing, opening into a blowing nozzle.
- a valve arranged in the blowing volume prevents gases from flow back into the compression volume.
- An object of the present invention is to provide a circuit breaker in which the pressure increase is stopped by simple means.
- the gas of the compression volume is evacuated through openings in the piston of blowing, these openings being associated with means allowing them to be kept closed between the start of the compression of the compression volume and closing the valve and open them when the valve closes, said means comprising fixed rods sliding in said openings of the piston, these rods comprising recesses or longitudinal notches or grooves or grooves on a portion of their length, chosen so that the hollowed out part rods enters the openings when the valve closed.
- the rods are arranged so as to lie for their greatest part inside the compression volume when the circuit breaker is in the on position.
- the stems the stems are arranged so as to be for the most part at outside the compression volume when the circuit breaker is in the engaged position.
- a cylinder, carrying the movable arcing contacts includes notches or grooves or grooves or recesses, cooperating with the piston for the evacuation of the compression gas at the end of compression.
- reference 1 represents a insulating jacket, for example ceramic, shaped cylindrical with axis xx, provided with fins such as the fin 2.
- the interior of the envelope contains a good gas dielectric properties, such as sulfur hexafluroride SF6, under pressure from a few thousand hectopascals.
- a good gas dielectric properties such as sulfur hexafluroride SF6
- a set fixed including a crown of contact fingers 3 for the passage of the permanent current, arranged at the end of a metal tube 4, and a metal rod 5 constituting the fixed arcing contact, the end of which is made in one alloy resistant to the effects of the arc.
- Tube 4 and rod 5 are connected to a first outlet of the circuit breaker, not shown.
- the room furthermore a mobile assembly comprising essentially two metallic parts substantially cylindrical 7 and 8, coaxial, mechanically secured by a transverse crown 9.
- a first end of the inner cylinder 7 (to the right of the figure) is connected mechanically to a control not shown; the second end of cylinder 7 wears a crown of contact 10 protected by a corona hood 11.
- These contact fingers constitute the movable arcing contact and cooperates with rod 5-5A.
- the cylinder 8 carries at a first end (on the left in Fig. 1) a cylinder 13 cooperating with the fingers 3 for the passage of the permanent current.
- the cylinders 7 and 8 and the crown 9 define two volumes V1 and V2, respectively designated by volume of blowing and compression volume.
- the blowing volume V1 opens on a blowing nozzle 14 fixed to the first end of the tube 8.
- the blowing volume V1 communicates with compression volume V2 through openings 16 practiced in crown 9; these openings can be obstructed by an annular valve 17 arranged so as to prohibit the passage of gas from the blowing volume to the volume compression.
- the compression volume V2 is closed at its end opposite the crown 9, by a fixed annular piston 19, arranged at the end of a fixed metallic tubular piece 20.
- This part 20 is electrically connected to its end opposite to that carrying the piston 19, at a second outlet not shown.
- Cylinder 8 is provided with sliding electrical contacts 21, for example of accordion type, to ensure the passage of current from tube 8 to the tubular part 20.
- a plurality of metal rods 22 fixed by one end to the end of the cylinder 7 near the crown 9, and passing through openings in piston 19. These rods bear over part of their length, recesses or grooves or notches or transverse grooves 22A, for example 3 in number, as shown in Fig. 3 which is a view of a section of a rod 22, made at the level of the zone grooves.
- the cylinder 7 may also include, on its outer periphery, grooves or indentations or rectilinear grooves axilaes 7A, arranged like the recesses or indentations or grooves or grooves 22A.
- the circuit breaker works as follows.
- the current flows from the first to second outlet when crossing successively the tube 4, the fingers 3, the cylinder 13 the cylinder 7, the sliding contacts 21 and the tube 20.
- Main contacts 3 and 13 are separate and the current switches to the arcing contacts.
- the gas of volumes V1 and V2 is compressed under the action of piston.
- the gas from the volume V1 relaxes and blows the arc.
- Fig. 4 shows an alternative embodiment of the invention in which the notched stems, referenced now 22 ', are arranged outside the volume of compression. Operation is identical to that described previously.
