Clamping encapsulation structure for arc barriers

The invention provides a clamping encapsulation structure for arc barriers. The clamping encapsulation structure comprises an upper arc barrier and a lower arc barrier, wherein the upper arc barrier comprises an inner spacer, an outer spacer and a magnetic conductive iron; the lower arc barrier comprises an inner spacer, an outer spacer and a magnetic conductive iron; one side of each inner spacer is provided with a first groove matched with a fixed contact while the other side is provided with a second groove buckled with the corresponding magnetic conductive iron; one side of each outer spacer is provided with a third groove buckled with the corresponding magnetic conductive iron, the two magnetic conductive irons are respectively embedded in the second groove and the third groove to be matched and connected with the same in a clamping manner by the two sets of inner spacers and outer spacers, the first grooves of the upper arc barrier and the lower arc barrier are opposite to each other and matched and connected with the fixed contact in a clamping manner. According to the clamping encapsulation structure, the magnetic conductive irons are respectively arranged on the upper arc barrier and the lower arc barrier in a clamping manner, the magnetic conductive irons are magnetized simultaneously and endowed with magnetic conduction functions, thus generating driving forces for driving arc and achieving the purpose of improving arc extinguishing capability of an arc extinguishing system.
