The invention relates to a switching appliance with a netted arc blowout device. The switching appliance comprises a switching appliance body, an arc extinguishing cover and a netted arc blowout device; an arc outlet is formed on one side of the switching appliance body; one side surface of the extinguishing cover is externally installed on the outer surface of the switching appliance body on the outer side of the arc outlet, an upper end and a lower end of the arc extinguishing cover are respectively provided with an opening, and multiple paths of exhaust holes are formed in the middle of the arc extinguishing cover; the netted arc blowout device is vertically arranged in the arc extinguishing cover and in the arc outlet, and the outer end surface of the netted arc blowout device is communicated with the multiple paths of exhaust holes. The netted arc blowout device is arranged in the arc outlet of the ordinary switching appliance body, high-temperature electrified particles in the arc are adsorbed by utilizing the netted arc blowout device, high-temperature neutral gas in the arc can permeate the netted arc blowout device and can be discharged outwards through the openings in the upper end and the lower end of the arc extinguishing cover, so that the deionization and arc blowout effect can be realized; moreover, the arc extinguishing speed can be accelerated, the arc combusting time is also reduced, and the switching appliance product actually has a zero-flashover effect.
