The patent No. is 200420054196.4 disclosed a kind of " permanent magnet mechanism circuit-breakers with manual rapid close and break brake function ", its manually quick on/off switch structure is that rocking arm, combined floodgate rocking arm, branch brake rocker arm are installed on the main shaft, divide the outer end of brake rocker arm and combined floodgate rocking arm that separating brake roller and combined floodgate roller are installed respectively, separating brake roller and combined floodgate roller respectively with transmission mechanism in the branch brake cam contact with the combined floodgate cam and carries out on/off switch and operate.Though this patent realizes manual on/off switch operation; but it realizes manual operation by two cams, two rollers, an eccentric wheel, an overdrive clutch cam, three rocking arms; complex structure, part is many, and it is many to drive points of engagement; increased the fault point; cost is higher, and inconvenience is safeguarded in processing, and this patent does not have on/off switch snap close protective device; the fault that can't avoid misoperation to cause, the security performance instability.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming; a kind of high voltage vacuum permanent magnet circuit breaker closing by hand, separating brake and snap close protective device thereof are provided; its part is few; simple in structure; the fault point is few; dependable performance realizes closing by hand, manual brake separating and switch-on latching, separating brake snap close defencive function by a cam and two rollers.
The technical solution used in the present invention is: a kind of high voltage vacuum permanent magnet circuit breaker closing by hand; separating brake and snap close protective device thereof; mainly comprise main shaft; the main shaft connecting lever; connecting plate; swivel plate and the square shaft that is connected in the case for circuit breaker inwall; the main shaft connecting lever is installed on the main shaft; hinged connecting plate one end of one end of main shaft connecting lever; the hinged swivel plate of the other end of connecting plate; swivel plate is installed on the rotation fulcrum and rotates on fulcrum; its technical characterstic is that the intracavity bottom of described swivel plate is interval with combined floodgate roller and separating brake roller; the below of swivel plate is provided with a cam that is installed on the square shaft, cam and combined floodgate roller; separating brake roller routing motion is respectively realized closing by hand; manual brake separating and switch-on latching; the protection of separating brake snap close.
This device cooperates with combined floodgate roller, separating brake roller respectively by a cam, drive successively that a swivel plate, a connecting plate, a main shaft connecting lever are realized manually closing, separating brake, and switch-on latching, separating brake snap close defencive function, four kinds of shared cams of function, combined floodgate roller, three parts of separating brake roller, need not increase parts peculiar, novel structure, part is few, and the fault point is few; Cam and roller are general part, and processing is simple, and cost is low; Electric operating and pure mechanical manual operation are not disturbed mutually, can not refuse branch because of manual operation produces, refuse to close fault, and stable performance helps producing the production efficiency height in batches.

Embodiment
The invention will be further described below in conjunction with accompanying drawing.
Among Fig. 1-4; a kind of high voltage vacuum permanent magnet circuit breaker closing by hand; separating brake and snap close protective device thereof; mainly comprise main shaft 1; main shaft connecting lever 2; connecting plate 3; swivel plate 4 and the square shaft 8 that is connected on the case for circuit breaker; omitted the locations of structures of case for circuit breaker in the accompanying drawing; main shaft connecting lever 2 is installed on the main shaft 1; hinged connecting plate 3 one ends of one end of main shaft connecting lever 2; the hinged swivel plate 4 of the other end of connecting plate 3; swivel plate is installed on the rotation fulcrum and around the rotation fulcrum and rotates; swivel plate 4 intracavity bottoms are interval with combined floodgate roller 6 and separating brake roller 7; the below of swivel plate 4 is provided with the cam 9 that is installed on the square shaft 8, cam 9 and combined floodgate roller 6; separating brake roller 7 routing motion is respectively realized closing a floodgate or separating brake.
Among Fig. 1, when carrying out the manual brake separating operation, driving cam 9 by rotation square shaft 8 rotates counterclockwise, after cam 9 turns over 180 °, the power spring energy stored in rotation that hangs over the square shaft head end discharges rapidly, drives cam 9 and promotes separating brake roller 7 with desin speed, and making swivel plate 4 is that the center of circle turns clockwise with rotation fulcrum 5, thereby an end that drives main shaft connecting lever 2 by connecting plate 3 upwards moves, and the other end of main shaft connecting lever 2 moves downward and makes circuit breaker success separating brake and be in gate-dividing state.
Among Fig. 2, when carrying out the closing by hand operation, driving cam 9 by rotation square shaft 8 clockwise rotates, after cam 9 turns over 180 °, the power spring energy stored in rotation that hangs over the square shaft head end discharges rapidly, drives cam 9 and promotes combined floodgate roller 6 with desin speed, and making swivel plate 4 is that the center of circle is rotated counterclockwise with rotation fulcrum 5, thereby an end that promotes main shaft connecting levers 2 by connecting plate 3 moves downwards, and the other end of main shaft connecting lever 2 moves upward and circuit breaker is successfully closed a floodgate and is in "on" position.
Among Fig. 3; when circuit breaker is in gate-dividing state; when if misoperation is carried out manual brake separating once more; after cam 9 rotates counterclockwise certain angle; will be withstood by combined floodgate roller 6 and end; the combined floodgate roller just plays the effect of separating brake snap close protection 6 this moments, has protected the gate-dividing state of circuit breaker, thereby has avoided the generation of fault.
Among Fig. 4; when circuit breaker is in "on" position; when if misoperation is carried out closing by hand once more; after cam 9 clockwise rotates certain angle; will be withstood by separating brake roller 7 and end; the separating brake roller just plays the effect of switch-on latching protection 7 this moments, has protected the "on" position of circuit breaker, thereby has avoided the generation of fault.
