Extinguishing chamber of a circuit breaker

摘要

An extinguishing chamber (10) is disclosed for a current circuit-breaker (100) or other device having disconnecting contacts. The chamber comprises a box (1) for location next to disconnecting contacts. The box has pair of side walls (11) and a rear wall (12). Deionization plates (13) made generally of ferromagnetic material are installed in the box perpendicularly to its walls. The walls of the box are formed with holes (111,112) designed to exhaust gases from the extinguishing chamber. The holes are divided into two groups (111, 121). The holes of the first group (111) are made in both the side walls of the box for connecting the area of the box via exhaust channels (101) with the area of the disconnecting contacts. The holes of the second group (121) are made in the rear wall of the box with free exhaust outside the extinguishing chamber.
