Feature of the present utility model is also,
The grid breach that first arc extinguishing grid pieces and the second arc extinguishing grid pieces are arranged is not on the same line.
The S-shaped setting of grid breach on first arc extinguishing grid pieces and the second arc extinguishing grid pieces.
The total quantity of the first arc extinguishing grid pieces and the second arc extinguishing grid pieces is 25.
The thickness of the first arc extinguishing grid pieces is 9.5mm, and the thickness of described second arc extinguishing grid pieces is 8mm.
The beneficial effects of the utility model are: the ceramic labyrinth type arc-extinguish chamber of a kind of contactor of the present utility model solves the excessive or crackly shortcoming of existing heavy load arc-extinguish chamber profile.A kind of contactor of the present utility model adopts the housing of the plastic material of resistance to electric arc with ceramic labyrinth type arc-extinguish chamber and utilizes alumina porcelain ceramic material arc extinguishing grid pieces and the arc extinguishing side plate of high strength and high specific heat, arc-extinguish chamber is not easily broken, damage, and on arc extinguishing grid pieces, carve the grid breach being provided with the design of S shape labyrinth type, thus add the contact area of the contactor of electric arc and ceramic material and elongated the creepage distance of electric arc, strengthen liberation, arc temperature is underspeeded quickening, not only reach the effect of extinguish arcs as early as possible, but also avoid damage arc-extinguish chamber parts, make to reach volume shared by equal arc quenching effect less.
Accompanying drawing explanation
