Description
Technical field
The invention belongs to breaker technical field, particularly a kind of manual and electric operating mechanism of circuit breaker and there is the reclosing circuit breaker of this operating mechanism.
Background technology
Much be arranged on outdoor power consumption equipment because distribution is wide, poor working environment has been brought a series of problem, such as: according to investigations, electric leakage switch tripping at the outdoor power consumption equipment of the about 20%-30% of weather of a thunderstorm, what some areas were the most serious surpasses 50%, makes large area outdoor equipment interruption of work.Meanwhile, also because of awful weather, restorer work in time, brings larger economic loss to national economy.In fact, and these tripping operations only need simple manual closing operation, just can restorer work.But owing to can not automatically again closing a floodgate after air switch, electric leakage switch tripping, need manually to close a floodgate one by one; Add that device distribution is too wide, number is too many, a lot of equipment is arranged on field, wilderness in addition, the mains switch that has is locked in residential dormitory, unit compound, and giving resumes work brings great difficulty and maintenance workload.Autoreclose breaker is used as the protections such as circuit and power-supply device electric leakage, overvoltage, under voltage and has automatic reclosing function; it is the in the situation that of electric leakage or short circuit; can in 0.05 second, cut off the electricity supply rapidly; can avoid accident to occur; guaranteed property and personal safety, faster more than 10 times than general air switch or fuse.There is " detecting before closing a floodgate " function, when supply power voltage abnormal (overvoltage, low-voltage), circuit exist the situation of electric leakage or short circuit, do not allow to close a floodgate, before accident occurs, stoped the generation of accident.
The operating mechanism that low-voltage circuit breaker is realized splitting or integrating lock is generally divided into manual-operating mechanism and motor-operating mechanism; in low-voltage circuit breaker far distance controlled field; general by motor-operating mechanism automatic brake separating and combined floodgate low-voltage circuit breaker, thus realize the protection to power circuit and motor.Motor-operating mechanism has two kinds, electric motor operating mechanism and operation electriomagnet mechanism, and motor-operating mechanism has advantages of that rotating speed can flexible, is many a kind of low-voltage circuit breaker motor-operating mechanisms of application at present.But when motor-operating mechanism breaks down, electric motor operating mechanism also needs to realize by manual-operating mechanism automatic brake separating and the combined floodgate of low-voltage circuit breaker, therefore, driving mechanism need to meet electric operating and manually operated function simultaneously.
In prior art, the engagement of many employing gears is transferred to the actuating force of motor on the handle of circuit breaker, thereby realize the combined floodgate sub-switching operation of circuit breaker, transmission by gear is applied to the actuating force of motor on the handle of circuit breaker, as Chinese patent literature CN102983016A discloses a kind of circuit breaker manual/electric integral operating mechanism, it comprise be arranged in circuit breaker, cover first, two fixed heads, the below of described the first fixed head is provided with mobilizable separating plate, one end of described separating plate is connected with the first fixed head by alignment pin, the other end arranges manual/auto transducer, on described separating plate, be provided with motor, on the main shaft of described motor, connect gear, described the second fixed head is arranged at a side of the first fixed head, on described the second fixed head, slide plate is set, the fixing tooth bar coordinating with gear on described slide plate, and described slide plate is in transmission connection by linkage part and operating grip.But employing gear transmission mode is higher to the required precision of part, complex structure, and part processing cost is high.
Chinese patent literature CN101577196A discloses a kind of electric control switch-on operating mechanism of miniature circuit breaker, comprise: a housing, a motor being fixed on housing, a shifting block being fixed on machine shaft, a lever, its run-on point is connected on housing, a pull bar, its one end is connected on lever, an arm-tie that is connected in the pull bar other end, this arm-tie is formed with the projected claw that can coordinate with small-size breaker handle, this invention is rotated by shifting block described in driven by motor, described lever is lifted, thereby pull the described projected claw of described arm-tie to pull circuit breaker handle, this mechanism causes that by lifting one end of described lever the pull bar that is fixed on its medium position rises, needed active force is larger, the being quick on the draw property of mechanism is lower, and, owing to needing to lift pull bar by lever in operating process, whole operating mechanism is had relatively high expectations to longitudinal space, and part is more, operating structure is installed comparatively complicated.
