Abstract
The invention discloses an arc extinguish chamber of a 110KV circuit breaker, which comprises a movable end conductor, an insulating cylinder, a fixed end conductor, a fixed end conductor support, a movable end conductor support and an operating mechanism capable of driving the movable end conductor to move along the axial direction, wherein the fixed end conductor and the movable end conductor are respectively surrounded by the fixed end conductor support and the movable end conductor support; and the insulating cylinder is arranged between the fixed end conductor support and the movable end conductor support and is connected with the fixed end conductor support and the movable end conductor support by fasteners so as to cause the contact parts to be positioned inside the insulating cylinder when the fixed end conductor and the movable end conductor are closed. The arc extinguish chamber solves the problem of interphase interference when the circuit breaker is cut off and improves the dynamic cut-off performance of the circuit breaker.
Description
Technical field
