Specific embodiment

Below with reference to the accompanying drawings and in conjunction with the embodiments this utility model is described in detail.It should be noted that not rushing In the case of prominent, the feature in following embodiment and embodiment can be mutually combined.

Fig. 1 and Fig. 2 provide the structural representation and top view of reclosing disconnecting mechanism, understand with reference to Fig. 1～Fig. 2, this reality Balance 1, citcuit-breaker transmission mechanism axle 2, balance coupling spindle 3, flange are changed with new reclosing disconnecting mechanism, including dynamic cooperation Bearing 4, breaker mechanism base plate 5, breaker mechanism main body 6, separating brake knob 7, combined floodgate knob 8, breaker energy storage main shaft 9.It is disconnected Road device energy storage main shaft 9 and the main spring for coupling（Not shown in figure）Connection, separating brake knob 7 and tripping spring（Not shown in figure）Connection Connect.Dynamic to coordinate conversion balance 1 to be arranged on the outside of breaker mechanism base plate 5 with flange bearing 4, balance coupling spindle 3 is located at open circuit The inner side of device actuator base 5, and coordinate conversion balance 1 to weld together and rotate coaxially with dynamic, flange bearing 4 is a tight fit in open circuit On device organization soleplate 5, balance coupling spindle 3 is passed through from 4 endoporus of flange bearing, and is coupled with citcuit-breaker transmission mechanism axle 2 and synchronous Rotate, combined floodgate knob 8, separating brake knob 7 and breaker energy storage main shaft 9 are arranged on the dorsad breaker mechanism of breaker mechanism main body 6 In the breaker mechanism die cavity of the opposite side of power transmission shaft 2, move and coordinate conversion balance 1 by the coupling with main spring and tripping spring Linkage, the dynamic breaking-closing operating for coordinating the rotation direction and killer switch of changing balance 1 are interlocked.

To, during breaker mechanism energy storage, breaker energy storage main shaft 9 being rotated counterclockwise, main spring can be driven to elongate storage Energy.When overhead transmission line is normal, combined floodgate knob 8 is rotated counterclockwise, the pulling force abrupt release of main spring drives citcuit-breaker transmission mechanism Axle 2 rotates clockwise 90 degree, and by the synchronous axial system of balance coupling spindle 3, coaxial dynamic cooperation conversion balance 1 rotates clockwise 90 Degree, is further driven to the closing operation of killer switch.In the pulling force release of main spring, tripping spring is pressurized to carry out energy storage, After the closing operation of killer switch, main spring can carry out stored energy operation again.

When false fault-signal occurs in alive circuit, separating brake knob 7 is rotated counterclockwise, the release of tripping spring energy, band dynamic circuit breaker Road device mechanism driving axle 2 rotates counterclockwise 90 degree, by the synchronous axial system of balance coupling spindle 3, coaxial dynamic cooperation conversion balance 1 90 degree are rotated counterclockwise, being further driven to killer switch carries out sub-switching operation.Sub-switching operation moment, Microcomputer Protection provide coincidence Lock signal, determines whether circuit really breaks down, and the main spring of energy storage is driven citcuit-breaker transmission mechanism by synchronous release Axle 2 rotates clockwise 90 degree, and by the synchronous axial system of balance coupling spindle 3, coaxial dynamic cooperation conversion balance 1 rotates clockwise 90 Degree, drives the closing operation of killer switch, killer switch to realize the sub-switching operation wink of reclosing function, i.e. killer switch Between complete closing operation.When it is false failure to confirm line fault after closing operation, killer switch will be continually maintained in combined floodgate State, it is to avoid circuit wrong diagnosis electrification.

Whole circuit breaker operation mechanism thickness H is not more than 196mm.

From the above, it may be appreciated that reclosing disconnecting mechanism of the present utility model, coordinates conversion balance and killer switch by dynamic Interlocking, realizes reclosing function, and whole circuit breaker operation mechanism thickness narrows down to 196mm, simple structure, without the need for original switch Cabinet makes any change, you can changes original operating mechanism, meets state's net reclosing requirement, substantially reduce distribution automation In the transformation cycle, workload is reduced, improve product stability, improvement cost is low.

Embodiment described above only expresses several embodiments of the present utility model, and its description is more concrete and detailed, But therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that common for this area For technical staff, without departing from the concept of the premise utility, some deformations and improvement can also be made, these all belong to In protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be defined by claims.
