Description
Technical field
The utility model relates to a kind of for miniature circuit breaker, can select the switching off/on device operated manually or automatically.
Background technology
The fault of most of circuit is instantaneous, and after circuit breaker trip, the insulation property one of circuit are restored, and namely drives operating mechanism to realize again closing a floodgate by auto recloser, greatly increases the reliability of line powering.The transmission mechanism of the auto recloser of traditional miniature circuit breaker, is rotated by motor-driven gear system, makes the moving contact rack of miniature circuit breaker stablize, reliably move to open position or closing position.The defect of this transmission mechanism is: can not adopt the operation manually realizing divide-shut brake, very flexible, can not with the compatibility of existing miniature circuit breaker, and once in transmission mechanism motor run break down, miniature circuit breaker then can not normally divide-shut brake, poor reliability.
Utility model content
The purpose of this utility model is the defect overcoming prior art, and provide a kind of structure simple, reliability is high, can select the manually automatic switching off/on device for miniature circuit breaker of automatic or manual divide-shut brake flexibly.
For achieving the above object, the utility model adopts a kind of so manually automatic switching off/on device for miniature circuit breaker, comprise pedestal and upper cover, described pedestal and described upper cover closed formation inner chamber, transmission mechanism and electronic-controlled installation is provided with in described inner chamber, described transmission mechanism comprises STATEMENT OF FEDERALLY SPONSORED, the motor driven by described electronic-controlled installation, be fixedly connected on the driving gear of the output shaft of described motor, and engage promotion by the flank profil of described driving gear, with the driven gear that rotates in the plane of described base parallel, one end fixed connection shaft of described STATEMENT OF FEDERALLY SPONSORED, described axle extends from inner chamber, described axle is in order to drive the operating mechanism of described miniature circuit breaker, the center card of described driven gear diametrically arranges a pair stop section, described STATEMENT OF FEDERALLY SPONSORED is provided with jut, described stop section can coordinate with described jut, STATEMENT OF FEDERALLY SPONSORED described in drive is rotated together.Compared with the prior art, the beneficial effects of the utility model are embodied in: by the setting of above structure, and when automatic operation closes a floodgate, STATEMENT OF FEDERALLY SPONSORED can be rotated along with the promotion of driven gear; When manual operation divide-shut brake, driven gear is static relative to pedestal, and the jut of STATEMENT OF FEDERALLY SPONSORED can rotate between the stop section of driven gear, on the divide-shut brake stroke of miniature circuit breaker, the operation of STATEMENT OF FEDERALLY SPONSORED is unobstructed, miniature circuit breaker freely manually can divide, close a floodgate, namely, the transmission mechanism of manual operation divide-shut brake and the transmission mechanism of automatic operation divide-shut brake can ideally together with compatibilities, user can select the mode of operation of divide-shut brake neatly, ensures that miniature circuit breaker meets the demand of power automation.
Especially, described pedestal arranges arcuate socket, the trip shaft of described miniature circuit breaker can be slided in described arcuate socket, the side of described driven gear and dropout sheet is extended in the position coordinated with described trip shaft.In the contact breaking course of miniature circuit breaker, promoting STATEMENT OF FEDERALLY SPONSORED without the need to driven gear, is only that dropout sheet touches trip shaft, and in the effect of internal spring force, operating mechanism accelerates to thread off.In addition, dropout sheet also can become the block mechanism of trip shaft, and when the auto recloser fault of miniature circuit breaker is out of control, stop trip shaft up, miniature circuit breaker keeps gate-dividing state, cannot close.

Embodiment
As Fig. 1, 2, shown in 7, a kind of manually automatic switching off/on device for miniature circuit breaker, comprise pedestal 1 and upper cover 8, pedestal 1 and the closed formation inner chamber of upper cover 8, transmission mechanism and electronic-controlled installation is provided with in inner chamber, transmission mechanism comprises STATEMENT OF FEDERALLY SPONSORED 7, the motor 4 driven by electronic-controlled installation, be fixedly connected on the driving gear 6 of the output shaft of motor 4, and engage promotion by the flank profil of driving gear 6, the driven gear 5 that the plane parallel with pedestal 1 rotates, one end fixed connection shaft 3 of STATEMENT OF FEDERALLY SPONSORED 7, axle 3 extends from inner chamber, axle 3 is in order to drive the operating mechanism of miniature circuit breaker, the center card of driven gear 5 diametrically is arranged a pair stop section 52, STATEMENT OF FEDERALLY SPONSORED 7 is provided with jut 71, stop section 52 can coordinate with jut 71, STATEMENT OF FEDERALLY SPONSORED 7 is driven to rotate together.
Pedestal 1 is arranged arcuate socket 11, the trip shaft 2 of miniature circuit breaker can be slided in arcuate socket 11, the side of driven gear 5 and dropout sheet 51 is extended in the position coordinated with trip shaft 2.
As shown in Fig. 2,7, when miniature circuit breaker is in disjunction state, moving contact separates with fixed contact, and the trip shaft 2 be connected with moving contact rack is positioned at the below of arcuate socket 11.When the auto recloser of miniature circuit breaker obtains switching signal, motor 4 entry into service, driving gear 6 on drive motor output shaft rotates, and then driven gear 5 rotates, stop section 52 on driven gear 5 promotes the jut 71 in STATEMENT OF FEDERALLY SPONSORED 7, STATEMENT OF FEDERALLY SPONSORED 7 is rotated together with driven gear 5, and the axle 3 fixing with STATEMENT OF FEDERALLY SPONSORED 7 drives the operating mechanism of miniature circuit breaker, starts to close a floodgate.As shown in Figure 3, when driven gear 5 turns to closing position, motor 4 starts to rotate backward, and after driven gear 5 is turned to original position, motor 4 shuts down, and so far, making process is complete, as shown in Figure 4.When miniature circuit breaker is in "on" position, moving contact and fixed contact close, when the auto recloser of miniature circuit breaker obtains sub-gate signal, motor 4 starts antiport, driven gear 5 is driven to rotate backward, dropout sheet 51 on driven gear 5 collides trip shaft 2, trip shaft 2 is moved to the below of arcuate socket 11, miniature circuit breaker accelerates to thread off under the effect of internal spring force, now, due to the operating mechanism separating brake of miniature circuit breaker, band moving axis 3 and clutch 7 turn round, for feed motion is next time ready.When driven gear 5 turns to trip positions, as shown in Figure 5, motor 4 rotates forward again, and drive driven gear 5 correcting action, so far separating brake is complete, as shown in Figure 6.
When the control signal wire no signal of the auto recloser of miniature circuit breaker time, when motor 4 starts antiport to trip positions, motor 4 shuts down, driven gear 5 keeps trip positions always, now, because trip shaft 2 can not move to the top of arcuate socket 11, therefore, miniature circuit breaker keeps gate-dividing state, cannot close.
