摘要：Wind load is the important factor influencing arc-extinguishing of arc. Establishing arc chain motion model of 35 kV parallel gap under wind load condition, the electromagnetic force, air resistance and wind force of a single arc element are analyzed by using the chain arc model. The arc motion parameters were solved. The arc anti-resistance and arc resistance are calculated; the criterion of arc extinguishing is defined; the arc burning time is calculated, and the arc burning time is obtained. Through the calculation of arc ignition time, it can be seen that the magnitude of wind load affects the arc free time. When the wind load increases, the arc ignition time will be shortened.
