Abstract
The utility model discloses a permanent magnetism operating device's manual minute brake gear, including installation bent plate, eccentric shaft and lever, the eccentric block of eccentric shaft non -central position department by the axle with on locating the axle head face is constituteed, and the eccentric shaft is rotationally connected on the installation bent plate, and the lever is connected with the eccentric shaft is perpendicular, and the eccentric block is located the terminal surface recess of the quiet iron core of permanent magnetism operating device during the use. The utility model has the advantages of being simple in structure and convenient in operation, use reliably.
Description
Technical field
This utility model relates to the manual switching-off device of a kind of permanent-magnet operating mechanism, belongs to High-Voltage Electrical Appliances field.
Background technology
Primary cut-out when various normal operating modes and failure mode point, closing operation be usually by secondary circuit point, closing circuit carry out what operation controlled, but in case of emergency have to manual brake separating, in order to excise rapidly fault.So, manual brake separating is the necessary function of chopper.
Monostable permanent magnetism operating mechanism all uses the tripping spring band moving contact that releases energy to complete separating brake task when separating brake, this is due to when breaker open operation, the power producing characteristics of spring compares the load characteristic meeting arc-chutes, i.e. at the disjunction initial stage, the pulling force that spring output is bigger, exerting oneself in stroke and be gradually reduced, such power producing characteristics is easier to realize higher just-off speed and relatively low this ideal situation of separating brake end speed.And when closing a floodgate, suction and the electromagnetic force driving coil electricity to produce by permanent magnet promote contact to complete combined floodgate task.
Manual circuit breaker device for permanent magnet mechanism the most with the most use is the principle design utilizing magnetic short circuited ring, this device needs dropout, a latching device, when combined floodgate hold mode, short-circuited conducting sleeve is maintained at upper end cover by latching device, and need to press during separating brake hand push button, buckle thread off, short-circuited conducting sleeve under the effect of inner spring with dynamic iron core surface adhesive by magnetic circuit short circuit.Therefore thread off, locking board must be reliable.But easily there is dropout, the phenomenon of latching device clamping stagnation in the most this manual switching-off device.Therefore, it is necessary to design a relatively reliable manual switching-off device.
Summary of the invention
The purpose of this utility model is to provide the manual switching-off device of a kind of service-strong permanent-magnet operating mechanism.
The manual switching-off device of the permanent-magnet operating mechanism that this utility model provides, including installing bent plate, eccentric shaft and lever, described eccentric shaft is by axle and is located in axial end the eccentric block at non-central location and forms, eccentric shaft is rotatably connected to install on bent plate, lever is vertical with eccentric shaft to be connected, and during use, eccentric block is positioned at the facing groove of permanent-magnet operating mechanism static iron core.
Manual brake separating is by using mechanical system to make the end face of iron core and static iron core pull open a gap, then the strength by tripping spring realizes separating brake, and manual switching-off device is used to produce this gap.
This utility model, by making the eccentric block on eccentric shaft prize dynamic iron core, makes dynamic and static iron core end face separate and realize separating brake, can be prevented effectively from dropout, latching device catching phenomenon that existing manual switching-off device easily occurs, use the most reliable, meanwhile, this utility model simple in construction, easy to operate.

Detailed description of the invention
As shown in Fig. 1 Fig. 4, this utility model includes installing bent plate, eccentric shaft and lever 5, and described installation bent plate is made up of side plate 2 and the bent plate 1 being fixed on side plate 2, and side plate 2 is bolted on the installing rack of permanent-magnet operating mechanism 6.Described eccentric shaft is by axle 3 and is located on axle 3 end face the eccentric block 4 at non-central location and forms, and axle 3 is installed in rotation in the hole on bent plate 1, and the eccentric block 4 on its end face inserts in the facing groove 611 outside static iron core 61.Lever 5 is vertical with axle 3 to be connected.
This utility model is fixed on the installing rack of permanent-magnet operating mechanism 6 by side plate 2, during manual brake separating, grasp lever 5 to be pressed downward against, lever 5 drives eccentric shaft turns, stretch into the eccentric block 4 in static iron core 61 facing groove 611 and upwards prize dynamic iron core 62, make, between the end face of iron core 62 and static iron core 61, the air gap occurs, the magnetic field of ferromagnetic circuit is weakened, dynamic retentivity between iron core 62 and static iron core 61 is the most weakened, when the counter-force of tripping spring is more than dynamic retentivity between iron core 62 and static iron core 61, chopper just realizes separating brake under the effect of tripping spring.Unclamping hands after breaker open operation, eccentric shaft resets, and eccentric block 4 comes back to, in the facing groove 611 of static iron core 61, prepare manual brake separating next time.
The above is only better embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any improvement and replacement carried out based on scheme of the present utility model and design all should be contained in protection domain of the present utility model.
