CAMERA FOR blowout protection devices and protection devices containing such CAMERA

摘要

1. The arc extinguishing chamber for electrical protection device, comprising an arc formation chamber containing a stationary contact and a movable contact, between which at the time of opening the arc is generated, wherein said arc formation chamber is communicated with the inlet of the second chamber, called the arc extinguishing chamber, wherein at at least one dividing wall arranged in the volume downstream of said arc extinguishing chamber, said wall extends in the direction of gas flow, so as to divide vysheupomyan uty volume in the direction of gas flow, and at least one outlet opening provides quenching gases which must be vented to the outside of the device, characterized in that the said separating wall (wall) (19) passes (pass) so as to create a substantially complete separation in the direction of flow to these holes and thereby create at least a first discharge channel (22) and a second discharge channel (23), each of said channels is connected to the outlet (25, 26) and provides achievement substantially complete separation between a first stream, called the base stream and a second stream, called secondary stream, said streams emerging from the output chamber opening (9) of the arc extinguishing and accordingly occur in the first (22) and second (23) channels, with the output openings (25, 26) and the chamber (9) arc extinguishing arranged relative to each other so that the gas flows out from the chamber (9) arc extinguishing substantially in the direction perpendicular to the direction, unto which the gas flows out of the apparatus through O
