Abstract
The utility model relates to a kind of operating mechanism of circuit breaker, comprise support, lever, tripping, snap close, upper connecting rod and lower link, lever is hinged on outside support, tripping is hinged in support, tripping upper end is connected with lever, upper small end be hinged in tripping with the junction of lever inside, lower end and the lower link of upper connecting rod are hinged, snap close is connected to support one end, snap close is provided with torsion spring, tripping one end is connected with snap close, a horizontal rectangular year button frame is formed centrally in described snap close, buckle side is carried to carrying bending the extending to form of button frame in tripping one end, the width carrying buckle side is slightly less than the width carrying button frame.It is large that carrying on snap close of the present utility model detains frame horizontal area, the area that year buckle side of tripping corresponds is also large, a year buckle side for tripping and snap close amasss increase and can prevent tripping slide fastener, and the edge length of carrying buckle side of tripping is also elongated, be not easy to find abrasion deformation, improve the mechanical endurance of operating mechanism.
Description
Technical field
The utility model relates to a kind of operating mechanism of circuit breaker, especially a kind of operating mechanism for moulded case circuit breaker.
Background technology
The operating mechanism of circuit breaker is the most basic element of character of whole low voltage switchgear, also be the direct drive unit that circuit breaker realizes divide-shut brake function, operating mechanism carry buckle device tripping can directly and snap close carry out the collision of year buckle side, but the easy slide fastener of existing operating mechanism tripping, slide fastener refer to mechanism's divide-shut brake or carry buckle in process, snap close can not pin tripping reliably, the degree of freedom of tripping can not be limited, mechanism is caused to refuse to close, cause mechanism's cisco unity malfunction, serious slide fastener phenomenon can cause the instability of electric power system, cause the large-area loss of power accident, impact is normal produces, and during slide fastener, it is enforceable hard friction between snap close and tripping, easily cause snap close and tripping distortion, year buckle side of heavy wear two parts, especially it is smaller that buckle side is carried in existing tripping, more easily there is abrasion deformation, operating mechanism is caused not carry button, the mechanical endurance of reducing mechanism.
Summary of the invention
For above-mentioned reasons, the purpose of this utility model is the operating mechanism of the circuit breaker providing a kind of mechanical endurance long.
For achieving the above object, the utility model adopts a kind of operating mechanism of circuit breaker, comprise support, lever, tripping, snap close, upper connecting rod and lower link, lever is hinged on outside support, tripping is hinged in support, tripping upper end is connected with lever, upper small end be hinged in tripping with the junction of lever inside, lower end and the lower link of upper connecting rod are hinged, snap close is connected to support one end, snap close is provided with torsion spring, tripping one end is connected with snap close, a horizontal rectangular year button frame is formed centrally in described snap close, buckle side is carried to carrying bending the extending to form of button frame in tripping one end, the width carrying buckle side is slightly less than the width carrying button frame.
The utility model is set to form lever shaft outside described support both sides further, and lever both sides form U-type groove, lever by U-type groove be enclosed within lever shaft with to be configured to hinged.
The both sides that the utility model is set to described support further form the cover plate tilted laterally, and the both sides of lever are inserted in inside the cover plate of support.
The beneficial effects of the utility model be operating mechanism snap close on to carry button frame horizontal area large, the area that year buckle side of tripping corresponds is also large, a year buckle side for tripping and snap close amasss increase and can prevent tripping slide fastener, and the edge length of carrying buckle side of tripping is also elongated, be not easy to find abrasion deformation, improve the mechanical endurance of operating mechanism.And operating mechanism structure is simple, easy for installation between each parts.
