Function.Therefore the current development trend of miniature circuit breaker is threaded off automatically except possessing traditional manual divide-shut brake and over-current and -load
Outside function, it is also necessary to there is automatic divide-shut brake and reclosing function, to realize remote control；Intelligent electric meter is especially combined,
Realize that arrearage automatic trip powers off, fill the function of expense automatic closing power transmission.
The important function of automatic reclosing：Feeder line fault is the failure of " instantaneity " mostly, and device is switched off in circuit
After rapid disconnection, the dielectric level of trouble point can voluntarily recover, and failure also just disappears immediately.Now, if open circuit disconnection
Device closes again automatically, namely automatic reclosing, it becomes possible to recovers normal power supply.Thus, automatic reclosing can provide confession
Electric reliability, reduce number and the time of line outage；For breaker in itself because mechanism is bad or protective relaying maloperation is made
Caused mistrip, it can also play correction.
Existing autoreclose breaker, breaker portion is substantially all without the function of quick-make.By motor driven
The transmission of circuit breaker handle interior axle is closed a floodgate, and makes the length of the closing time of breaker be influenceed by power of motor.Some product electricity
The big closing speed of acc power is relatively fast, and some is then slow.And power increase too conference makes the cost of product significantly increase.Production
Product possible speed in closing course is slower, once distance closely causes punch through very much electric discharge between contact, and contact can not close in time
Close, gently then increase contact loss, it is heavy then easily cause security incident.
Utility model content
In order to overcome the shortcomings of background technology, the utility model provides a kind of automatic reclosing operation dress of miniature circuit breaker
Put, mainly solve the problems, such as that the automatic reclosing operation device combined floodgate of present miniature circuit breaker is not rapid enough.
Technical scheme is used by the utility model：
A kind of automatic reclosing operation device of miniature circuit breaker, including housing, the housing is interior to be provided with by power source band
The first dynamic rotating disk of turn, first rotating disk are used to drive trundle to make breaker closing, coaxially corresponded on the rotating disc
Provided with the second rotating disk, the second rotating disk eccentric part is provided with connecting rod, and slideway is additionally provided with the housing, is provided with and slides in the slideway
The dynamic sliding block coordinated, the sliding block are connected with the connecting rod, and energy storing members are provided between the slide bottom and the sliding block, described
The axial line of slideway passes through the center of circle of first rotating disk.
The beneficial effects of the utility model are：The utility model provides a kind of automatic reclosing operation dress of miniature circuit breaker
Put, using crank block dead point principle, after motor drives the second driven by rotary disc sliding block to cross dead point, the storage that acts on sliding block
The energy release of energy part, makes sliding block move linearly, and sliding block promotes the second rotating disk to continue to rotate, crank rotor plate band dynamic circuit breaker by connecting rod
Road device handle closes a floodgate.By energy storing members energy storage and then discharge, the no very big requirement of power to motor is simple in construction, closes a floodgate fast
Speed.
