Description

Arc extinguishing system of circuit breaker
Technical field
Electrical equipment is the utility model is related to, relates in particular to a kind of arc extinguishing system of circuit breaker.
Background technology
Switching on and off for breaker is needed to rely on moving contact and static contact, and static contact is typically fixedly mounted on pedestal, Moving contact activity installation, moving contact can be contacted or separated with static contact, reach the purpose for being switched on or switched off breaker.Moving contact Electric arc can be produced, it is necessary to rapidly by arc extinction after being separated with static contact, prevent it from restriking.Existing breaker contact system is adopted It is that reaction spring pulls moving contact to be spaced out with static contact, electric arc is extinguished by the method for elongating arc.It is such to go out Arc method is not rapid enough, and it is not clean enough to frequently result in arc extinguishing.
Utility model content
The utility model passes through spring mainly solving the technical problems that provide a kind of arc extinguishing system of circuit breaker by two pieces The arc extinguishing baffle plate of driving is by the arc extinction between moving contact and static contact, and arc extinguishing is thoroughly rapid, and effect is good.
To achieve the above object, the utility model provides following technical scheme:The arc extinguishing system of circuit breaker includes insulation Shell, insulation crust both ends are separately installed with static conductive rod and moving conductive rod, and static conductive rod and moving conductive rod are outer through insulation Shell, static conductive rod are located at one end inside insulation crust and are fixedly connected with static contact, and moving conductive rod is located at one end inside insulation crust Moving contact is fixedly connected with, moving contact is arc-shaped close to static contact one end, and insulation crust bottom is symmetrically installed with bullet up and down Spring, two spring ends are mounted on flat arc extinguishing baffle plate, when moving contact and static contact are bonded, two spring-compresseds, and two arc extinguishings When moving contact side, moving contact and static contact separate, two springs stretch baffle wedge, and two arc extinguishing baffle plates are bonded to each other and positioned at quiet Among contact and moving contact.
As the further optimization of the technical program, insulation crust and the arc extinguishing baffle plate manufactures by ceramic material.
As the further optimization of the technical program, the static contact, moving contact, static conductive rod, moving conductive rod are by copper Alloy manufactures, and static contact and static conductive rod are overall structure, and moving contact and moving conductive rod are overall structure.
As the further optimization of the technical program, the spring is by stainless steel making.
Beneficial effect using above technical scheme is:The insulation crust bottom of the arc extinguishing system of circuit breaker is symmetrical up and down Spring is installed, two spring ends are mounted on arc extinguishing baffle plate, and when two springs stretch, two arc extinguishing baffle plates are bonded to each other and are located at Among static contact and moving contact.The arc extinguishing system of circuit breaker static conductive rod can be connected by wire and moving conductive rod accesses breaker In circuit, when moving contact is bonded with static contact, circuit is channel status.When moving contact by moving conductive rod drive and and static contact During separation, breaker circuit is off state, and electric arc is produced between static contact and moving contact, and now two springs promote two arc extinguishings gear Plate is kept off between static contact and moving contact, can be quickly good by arc extinction, arc quenching effect.
