Abstract

The invention discloses an electric line arc extinguishing method, which belongs to the field of electric line arc extinguishing, and comprises the following steps: S1, an arc extinguishing system is established, the arc extinguishing system comprises a contact system, an arc striking channel and an arc extinguishing chamber, S2, the arc extinguishing chamber in S1 comprises an arc extinguishing cover and an arc extinguishing grid sheet group, and the arc extinguishing cover comprises two isolation plates which are respectively located at two sides of the arc extinguishing grid sheet group; the arc extinguishing grid piece group comprises a plurality of arc extinguishing grid pieces, connecting assemblies are arranged at the end parts, close to the isolation plate, of the arc extinguishing grid pieces, each connecting assembly comprises a connecting piece and a locking piece, and the connecting pieces sequentially penetrate through the arc extinguishing grid pieces and the bearing plate from top to bottom and then are fixedly connected with the locking pieces at the bottom; the arc extinguishing grid pieces and the bearing plate are provided with through holes for the connecting pieces to penetrate through. According to the arc extinguishing device, the arc extinguishing grid pieces and the bearing plate are fixed through the connecting assemblies by means of cooperation of the sliding grooves and the sliding blocks, the installation procedure of the arc extinguishing grid pieces is simplified, and the arc extinguishing grid pieces and the arc extinguishing cover are fixed more firmly.

Description

technical field [0001] The invention belongs to the field of arc extinguishing of power lines, and in particular relates to a method for extinguishing arcs of power lines. Background technique [0002] In electrical appliances with contacts, the process of connecting and breaking the current of the contacts is often accompanied by the generation and extinguishment of arcs. Arcs are a gas discharge phenomenon that is harmful to electrical appliances. It is precisely because arcs can cause damage to electrical appliances. , so it is necessary to perform arc extinguishing operation. Using arc extinguishing system to extinguish arc is one of the basic methods for extinguishing arc. The arc extinguishing system includes contact system, arc starting channel and arc extinguishing chamber. Under the action, it is pulled into the arc extinguishing grid, and a long arc is divided into multiple short arcs. When the AC current crosses zero, all the short arcs are extinguished at the sa...
