Abstract

The invention relates to the field of vacuum circuit breakers, in particular to an explosion-proof vacuum circuit breaker arc extinguishing chamber, which comprises a ceramic housing (1); a fixed endcover board (2) and a movable end cover board (3) which are arranged at the two ends of the ceramic housing (1) respectively; and conductors (4) which pass through the fixed end cover board (2) and the movable end cover board (3) respectively, wherein the end parts of the conductors (4) are respectively provided with a contact (5), the conductor (4) passing through the movable end cover board (3)is sleeved by a corrugated pipe (6); the upper and lower parts of the outer wall of the ceramic housing (1) are respectively provided with a groove section (7); a ring (8) is sleeved on the groove section (7); the ceramic housing (1) is externally sleeved by a protective net (9); and the two ends of the protective net (9) are connected with the rings (8) at the two ends respectively. The ceramic housing (1) can be prevented from bursting and splashing, and meanwhile, a part of explosion kinetic energy is absorbed.

Description

technical field [0001] The invention relates to the field of vacuum circuit breakers, in particular to an arc extinguishing chamber of an explosion-proof vacuum circuit breaker. Background technique [0002] The vacuum circuit breaker mainly uses the arc extinguishing chamber to realize the disconnection of the circuit. The arc extinguishing chamber is composed of a ceramic shell, a fixed end cover and a moving end cover to form a sealed vacuum environment. The operating mechanism drives the moving conductor and the fixed conductor. Separation can realize arc extinguishing. In the prior art, due to the high vacuum degree in the arc extinguishing chamber and the heat release during the arc extinguishing process all the year round, if the quality of the arc extinguishing chamber is poor, explosion may occur. Contents of the invention [0003] The object of the present invention is to provide an explosion-proof vacuum circuit breaker arc extinguishing chamber to solve the pr...
