The transmission fixed mechanism is made of adapter sleeve (8), driving connecting lever (9), organization soleplate, and organization soleplate comprises base plate (13), combined floodgate limiting plate (14), separating brake limiting plate (15), supporting plate (17).Adapter sleeve (8) links together the drive rod (7) and the driving connecting lever (9) of permanent magnet mechanism, the main shaft (18) of breaker body (19) passes base plate (13) and is enclosed within the driving connecting lever (9), combined floodgate limiting plate (14) and separating brake limiting plate (15) are positioned at the both sides up and down that drive connecting lever (9), the below that supporting plate (17) is positioned at permanent magnet mechanism, and combined floodgate limiting plate (14), separating brake limiting plate (15), supporting plate (17) all are fixed on the base plate (13).
In the such scheme, when permanent magnet mechanism was put sidewards, adapter sleeve (8) one ends linked to each other with the drive rod (7) of permanent magnet mechanism, and the other end links to each other with driving connecting lever (9) by connecting lever (22) with after connecting plate (21) is connected again.
The designer of the technical solution of the utility model replaces the spring energy-storage operating mechanism with permanent-magnet manipulating mechanism, makes that product structure is simple, non-maintaining, reliability is high.Close a floodgate or during the separating brake position, no current passes through in the coil when circuit breaker is in, the low magnetoimpedance passage that permanent magnet utilizes dynamic and static core to provide will move iron core and remain on and close a floodgate or the separating brake position, and without any need for mechanical interlocking.During work, electric current in combined floodgate or the switching winding produces magnetic potential, the magnetic field superposition that magnetic field that is produced by coil in the dynamic and static iron core and permanent magnet produce is synthetic, moving iron core is together with fixed thereon drive rod, under the power effect of resultant magnetic field, in official hour,, promote moving contact and be switched on or switched off with the transmission device of speed drive Switch main body of regulation, thereby realize the pass closing operation of switch, finish controlled function.
This product is mainly used in LW3-12 type series outdoor high-voltage SF6 circuit breaker, and CHL-12 type series outdoor high-voltage SF6 automatic recloser replaces behaviour and plays energy storage operation machine and other mechanical operating mechanism (comprising electromagnetic operating mechanism).
The major advantage of this product can be summarized as the following aspects:
1, simple in structure, parts are few, reliability is high, simple to operate.(A), the moving component of this product has only one, and spring operating mechanism parts nearly 100 or more than.(B), the switch divide-shut brake coil of this product can link to each other with the electronic-controlled installation of power supply power supply.This electronic-controlled installation is finished coil electricity operation, overcurrent protection, automatic reclosing and the various diagnosis of self etc. by the control unit of a particular design; need not mechanical release; fundamentally overcome the reliable problem of operation of the release that spring operating mechanism and electromagnetic mechanism be difficult to overcome, made that the operation of mechanism is very simple.
2, adopt " two formulas " bistable state principle, its moving iron core or at open position, or, do not have specious intermediateness in make position.
3, non-maintaining degree height is suitable for frequent operation.Because this product is equivalent to the switch of a two-way position, thereby does not need machinery control or pin function.Such structure is easy to realize 10000 times divide-shut brake cycling and seldom keeps in repair.So, adapt to the place of frequent operation by the SF6 or the non-maintaining degree height of vacuum switch of its operation.
