Abstract
The utility model relates to a kind of arc quenching system of circuit breaker, comprise fixed contact and arc-extinguish chamber, fixed contact comprises integrated contact body and fixed contact, the arc extinguishing grid pieces that arc-extinguish chamber comprises two arc-extinguish chamber walls and is arranged between two arc-extinguish chamber walls, arc extinguishing grid pieces one end forms U-shaped arc end, contact body is provided with magnet in the downside of fixed contact, and multi-disc arc extinguishing grid pieces is by fan-shaped array between two arc-extinguish chamber walls, and arc extinguishing grid pieces is less than the other end at the crack of arc end.Arc extinguishing grid pieces is arranged to fan-shaped, electric arc is after arc end is inhaled into, extinguishing arc is elongated gradually by arc extinguishing grid pieces, add on fixed contact, by permanent magnetism installing rack, magnet is installed, magnet can play arc blowing function when moving contact disjunction, the electric arc of production is blown in arc-extinguish chamber faster, improves arc quenching effect.
Description
Technical field
The utility model relates to a kind of arc quenching system, especially a kind of arc quenching system for moulded case circuit breaker.
Background technology
Existing moulded case circuit breaker adopts arc-extinguish chamber arc extinguishing at moving contact and fixed contact side usually, the structure of arc-extinguish chamber is between arc-extinguish chamber wall, arrange parallel multi-disc arc extinguishing grid pieces, when moving contact disjunction, the electric arc of generation is carried out segmentation arc extinguishing by multi-disc arc extinguishing grid pieces, but because arc extinguishing grid pieces be arranged in parallel, can't be elongated after electric arc segmentation, arc quenching effect is poor.
Summary of the invention
For above-mentioned reasons, it is strong that the purpose of this utility model is to provide a kind of breaking capacity, has the arc quenching system of the circuit breaker of arc extinguishing ability.
For achieving the above object, the utility model adopts a kind of arc quenching system of circuit breaker, comprise fixed contact and arc-extinguish chamber, fixed contact comprises integrated contact body and fixed contact, contact body comprises the fixed contact supporting part for carrying fixed contact, for introducing the wire connecting portion of electric current and the kink for connecting fixed contact supporting part and wire connecting portion, fixed contact is arranged on the upper side of fixed contact supporting part, the arc extinguishing grid pieces that arc-extinguish chamber comprises two arc-extinguish chamber walls and is arranged between two arc-extinguish chamber walls, arc extinguishing grid pieces one end forms U-shaped arc end, magnet is provided with on the downside of the fixed contact supporting part of described contact body, multi-disc arc extinguishing grid pieces presses fan-shaped array between two arc-extinguish chamber walls, arc extinguishing grid pieces is less than the other end at the crack of arc end.
The utility model is set to described arc-extinguish chamber arc extinguishing grid pieces topmost further and extends to form cover plate to arc end.When cover plate can lift to extreme higher position in moving contact disjunction, can be attracted to electric arc, the cover plate protracted is close to the distance of moving contact, and striking is effective.
The downside that the utility model is set to described fixed contact supporting part is further fixedly installed permanent magnetism installing rack, and magnet is arranged in permanent magnetism installing rack.
The utility model is set to described permanent magnetism installing rack further and comprises the epipleural be connected with fixed contact supporting part, the lower side panel carrying magnet and connect the connecting plate of epipleural and lower side panel.
The utility model is set to described arc extinguishing grid pieces further and is one in front and one in back staggered by arc end.
The utility model to be set in described arc-extinguish chamber arc extinguishing grid pieces bottom forms magnetic bar further, and magnetic bar is arranged on magnet one end.Magnetic bar can draw magnetic and improve magnetic blowout effect.
It is fan-shaped that the beneficial effects of the utility model are that arc extinguishing grid pieces is arranged to, electric arc is after arc end is inhaled into, extinguishing arc is elongated gradually by arc extinguishing grid pieces, add on fixed contact, by permanent magnetism installing rack, magnet is installed, magnet can play arc blowing function when moving contact disjunction, the electric arc of production is blown in arc-extinguish chamber faster, improves arc quenching effect.
