Abstract
The utility model discloses an arc-extinguishing chamber of a low-voltage circuit breaker, comprising a left arc insulating lateral wall, a right arc insulating lateral wall and a plurality of first and second arc-extinguishing gates arranged between the left and the right arc insulating lateral walls. Both lateral faces of each first arc-extinguishing gate are provided with two symmetrical convex members of the same size, both lateral faces of each second arc-extinguishing gate are provided with two grooves of the same size, the left and the right arc insulating lateral walls are provided with a plurality of grooves and first opening grooves and second opening grooves which are all matched with the convex members and the grooves on the lateral faces of the second arc-extinguishing gate, the first and the second opening grooves are arranged at both sides of the left and the right arc insulating lateral walls with openings arranged oppositely, and the grooves on the left and the right arc insulating lateral walls and the first and the second opening grooves are staggered. The arc-extinguishing chamber of the low-voltage circuit breaker simplifies location of the gates and rivet connection of the arc-extinguishing chamber, and is reliable to use.
Description
Technical field
The utility model relates to a kind of low-voltage circuit breaker, relates in particular to its arc control device parts.
Background technology
The breaking capacity of low-voltage circuit breaker depends on the arc extinguishing ability of driving distance, breaking speed and arc-control device of circuit breaker dynamic/static contact, moulds the case low-voltage circuit breaker arc-control device and mainly is made up of arc control device and contact system.Wherein the structure of arc control device is directly connected to the effect of arc extinguishing, arc control device generally by arc extinguishing grid pieces and fixedly the arc sidewall of arc extinguishing grid pieces form, there is the groove fit on boss and the arc sidewall both sides of arc extinguishing grid pieces, by riveted joint arc extinguishing grid pieces and arc sidewall are attached to together, traditional arc control device are when riveted joint, and each sheet grating sheet all needs riveted joint, locate and support each sheet arc extinguishing grid pieces at anchor clamps of process need of riveted joint, cause the arc control device riveting process numerous and diverse, production efficiency is low.
Summary of the invention
At the problem of above-mentioned existence, the purpose of this utility model provides a kind of simple in structure, easy to assembly, arc control device of linking reliable low-voltage circuit breaker.
The technical solution adopted in the utility model is: comprise an a pair of left side, right arc sidewall and be positioned at an a pair of left side, between the right arc sidewall several first, second arc extinguishing grid pieces, have two identical and symmetrical boss of size on the two sides of first arc extinguishing grid pieces, have two identical and symmetrical grooves of size on the two sides of second arc extinguishing grid pieces, a left side, have some and boss on the right arc sidewall, the groove that groove matches and first, second open slot, first, second open slot is arranged on a left side, the both sides and the opening direction of right arc sidewall are opposite, groove location and first, second open slot position staggers mutually.
The beneficial effects of the utility model are:
1, all need locate the situation of riveted joint than each sheet arc extinguishing grid pieces of traditional arc control device, the utility model only need be riveted two arc extinguishing grid pieces with boss near arc sidewall two ends, other grid sheet cooperates with the arc sidewall with groove, abdicates the riveted joint space of the arc extinguishing grid pieces with boss with groove.Only need the riveted joint of grafting by some second arc extinguishing grid pieces and arc separating wall and at least two first arc extinguishing grid pieces and arc separating wall promptly to realize the assembling of arc control device, simplified the location of grid sheets and the riveted joint of arc control device.
2, the arc extinguishing grid pieces with groove only need be worked good with the arc sidewall, rivets the location of promptly having realized all grid sheets by the arc extinguishing grid pieces and the sidewall of tool boss again, makes arc quenching chamber structure simple, and is easy to assembly, uses reliable.
