Description
Technical field
The utility model belongs to breaker technical field, particularly a kind of manual and electric operating mechanism of circuit breaker and have 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, at the electric leakage switch tripping of the outdoor power consumption equipment of the about 20%-30% of weather of a thunderstorm, what some areas were the most serious exceedes 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; ensure property and personal safety, faster more than 10 times than general air switch or fuse.There is " detecting before closing a floodgate " function, in the time that 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 in the time that 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.
