To achieve these goals, the technical solution adopted for the present invention to solve the technical problems is: micro-disconnected type pre-payment automatic reclosing, comprise breaker body and automatic closing device, the folding sneek of described breaker body and the folding sneek of automatic closing device are connected, automatic closing device comprises housing and circuit board, the entirety of the folding sneek of automatic closing device is a lever, lever is connected on housing by the fulcrum hole in the middle part of it, the lever end being positioned at enclosure interior is in transmission connection by intermediate slider and linear moving mechanism one direction, linear moving mechanism is connected with electric-motor drive by decelerator, the glide direction being positioned at linear moving mechanism is provided with two spacing contact-making switches, two spacing contact-making switches and motor are all electrically connected with circuit board.
The present invention is worth it is further noted that, described lever is one with the lever of knuckle, the knuckle summit of lever is positioned on the axis of fulcrum hole, the bar segment length being positioned at enclosure interior lever is greater than the bar segment length of the lever being positioned at outside, and the angle between two-part bar section is 90 ° to 180 °, lever is connected on by fulcrum hole turning set on fixed axis that housing sidewall is fixedly installed.
The present invention is worth it is further noted that, described linear moving mechanism comprises the linear moving mechanism slide be solidified as a whole with enclosure interior sidewall, a spur gear is provided with in the middle part pedestal of linear moving mechanism slide, described spur gear and the rack slide be slidably mounted on linear moving mechanism slide are in transmission connection, be provided with a step in the middle part of the back of described rack slide, an end of rack slide is provided with projection.
The present invention is worth it is further noted that, one end of described intermediate slider is provided with the block that the step one direction that arranges in the middle part of the back with rack slide fastens, intermediate slider offers long kidney-shaped chute, intermediate slider is socketed by the sliding bar of long kidney-shaped chute with the lever end being arranged on enclosure interior, slide bar and lever body of rod spatial vertical.
The present invention is worth it is further noted that, described two spacing contact-making switches are all fixedly mounted in holder, wherein a holder is fixedly installed on linear moving mechanism slide one end, and another holder is fixedly installed on the madial wall of the housing of another side of linear moving mechanism slide.
Beneficial effect of the present invention: the folding of the present invention and prepayment breaker is pulled to turn round and is connected, integrally mounted formula structure, without the need to power transmission of closing a floodgate manually, safely and fast, namely the expense that can realize hands over high efficiency power transmission namely.

Embodiment
Micro-disconnected type pre-payment automatic reclosing as shown in Figure 1-Figure 3, comprise breaker body 1 and automatic closing device 2, the folding sneek of described breaker body 1 and the folding sneek of automatic closing device 2 are connected, and (this execution mode adopts fixed pin shaft 14 to be in transmission connection, fixed pin shaft 14 runs through the folding sneek of breaker body 1 and the folding sneek of automatic closing device 2, all folding sneeks are made to connect into entirety, realize upwards beat or downwards beat together), automatic closing device 2 comprises housing 3 and circuit board, the entirety of the folding sneek of automatic closing device 2 is a lever, lever is connected on housing 3 by the fulcrum hole in the middle part of it, the lever end being positioned at housing 3 inside is in transmission connection by intermediate slider 4 and linear moving mechanism one direction, linear moving mechanism is in transmission connection by decelerator and motor 6, the glide direction being positioned at linear moving mechanism is provided with two spacing contact-making switches 5, two spacing contact-making switches 5 and motor 6 are all electrically connected with circuit board.
Preferably, described lever is one with the lever of knuckle, the knuckle summit of lever is positioned on the axis of fulcrum hole, the bar segment length being positioned at housing 3 internal lever is greater than the bar segment length of the lever being positioned at housing 3 outside, and the angle between two-part bar section is 90 ° to 180 °, lever is connected on by fulcrum hole turning set on fixed axis 7 that housing 3 sidewall is fixedly installed.This design of lever can make the moment of transmission increase, and mechanism is not very complicated.
Preferably, described linear moving mechanism comprises the linear moving mechanism slide 8 be solidified as a whole with housing 3 internal side wall, a spur gear is provided with in the middle part pedestal of linear moving mechanism slide 8, described spur gear and the rack slide 9 be slidably mounted on linear moving mechanism slide 8 are in transmission connection, be provided with a step in the middle part of the back of described rack slide 9, an end of rack slide 9 is provided with projection.Rack-and-pinion is the mechanism that classical rotation becomes movement, simply handy, be convenient to implement, step in the middle part of the back of rack slide 9 abuts transmission in order to realize with the one direction of intermediate slider 4, in a making process, rack slide 9 is positioned at one end of linear moving mechanism slide 8, to the other end slippage of linear moving mechanism slide 8 under the driving of motor 6, and promote intermediate slider 4 and move thus drive the swing of lever to realize feed motion, now, intermediate slider 4 motor 6 after a spacing contact-making switch 5 of conflicting reverses, rack slide 9 reverse shuffle, when rack slide 9 conflicts another limit switch 5, motor quits work, (namely rack slide 9 resets tooth bar transfixion, one is the swing space position abdicating lever when circuit breaker disconnects, be preparation of next time closing a floodgate besides).
Preferably, one end of described intermediate slider 4 be provided with the back of rack slide 9 in the middle part of the block 10 that fastens of the step one direction that arranges, intermediate slider 4 offers long kidney-shaped chute 11, intermediate slider 4 is slidably socketed with the slide bar 12 of the lever end being arranged on housing 3 inside by long kidney-shaped chute 11, slide bar 12 and lever body of rod spatial vertical.
Preferably, described two spacing contact-making switches 5 are all fixedly mounted in holder 13, wherein a holder 13 is fixedly installed on linear moving mechanism slide 8 one end, and another holder 13 is fixedly installed on the madial wall of the housing 3 of another side of linear moving mechanism slide 8.
