Description
Technical field
The invention belongs to contactor construction design field, and in particular to a kind of rapid box vacuum contactor.
Background technology
In current power system, what high, medium and low voltage contactor and breaker were used is all electromagnetic type divide-shut brake, electromagnetism point
What the speed of combined floodgate was realized mainly by the volume size of coil and magnet, because vacuum contact is to come arc extinguishing, vacuum by vacuum tube
Pipe is made up of self-closing power and contact stage clip, and the vacuum contactor that conventional electric power is used has contact stage clip and separating brake anti-in design
Power spring is mentality of designing, so the coil and magnet volume ratio of design are larger, vacuum tube could be shifted onto closing position, because
The self-closing power and overtravel spring force that the power of promotion is greater than vacuum tube also have reaction spring power summation.The bigger closing time of coil
Longer, because electromagnet coil has the presence of inductance, the size of inductance concerns the speed of contact closing time.
The conventional contact of domestic market can not meet the new production such as present photovoltaic solar, wind-power electricity generation
Industry.Because these new generatings are carried out when being connected to the grid in the case where not powering off.Contactor is exactly wherein grid-connected crucial
Original paper, so requiring high to contactor closing time, it is necessary to which control is in below 3ms, and conventional contact can not be realized.
The content of the invention
The present invention is directed in the market conventional contact in the application of new industry by being limited, and proposes a kind of quick box
Permanent magnetism monopole vacuum contactor.
The technical solution adopted by the present invention is as follows：
Provided with the vacuum placed side by side in a kind of quick box permanent magnetism monopole vacuum contactor, including casing, the casing
Switching tube, permanent magnet mechanism, it is characterised in that：Overtravel spring, the overtravel spring one are provided with below the vacuum switch tube
End is fixedly mounted on bottom half, and the other end is located at the lower section of vacuum switch tube and the moved end connecting lever of vacuum switch tube is not contacted,
The permanent magnet mechanism includes back-moving spring, the reset bullet are housed below permanent magnet, electromagnet and dynamic iron core, the dynamic iron core
The other end of spring is fixedly mounted on bottom half；Also include insulation connecting lever, the insulation connecting lever is located at vacuum switch tube and permanent magnetism
Mechanism downward vertical contact back-moving spring and overtravel spring, its one end are fixedly mounted on the side wall of casing, and the other end is fixed
Dynamic iron core lower end is connected, the insulation connecting lever is used for energy storage of closing a floodgate with overtravel spring；It is additionally provided with above the permanent magnet mechanism
Manual brake separating component；The manual brake separating component includes the connecting lever for being connected to permanent magnet mechanism upper end, the other end of the connecting lever
Manual brake separating button is installed, the manual brake separating button is arranged on casing top；Also include the conductive plate for going deep into casing, it is described
Conductive plate connects vacuum switch tube moving contact in casing by wire.
The overtravel spring be butterfly spring, pressure stability, it is easy to adjust that there is provided combined floodgate power.The permanent magnet mechanism
Permanent magnet keep.
Pass through the arm of force ratio of the connecting lever so that the manually operated dynamics of needs is smaller, and then cause electromagnet stroke
It is small, it is easily controlled electromagnet and promotes dynamic iron core dropout to complete separating brake action.
The present invention is operationally：Mainly carried out with the self-closing power and overtravel spring of vacuum switch tube in manual brake separating
Energy storage, switches on power, and the coil in permanent magnet jar carries out promoting dynamic iron core to reach closing position after excitation, and at this moment coil passes through
Auxiliary contact, which are cut off the electricity supply, completes combined floodgate task.
Beneficial effects of the present invention are embodied in：
The present invention is by using manual brake separating component separating brake, and overtravel spring directly closes a floodgate.It is manually operated manual during separating brake
Separating brake component, the dynamic iron core of permanent magnet mechanism props up overtravel spring by the connecting lever that insulate, and realizes separating brake；During combined floodgate, permanent magnet mechanism
Dynamic iron core thread off, overtravel spring acted directly on the moving contact of vacuum switch tube, vacuum switch tube negative pressure and
Directly closed a floodgate in the presence of overtravel spring, add the pressure of vacuum switch tube moving contact, overcome its spring problem, broken through
The problem of conventional contactor and breaker bounce.Also closing time is substantially increased, is reached within 1ms, it is whole to close a floodgate
Time reaches below 3ms, is that solar energy, wind-electricity integration solve a great problem, also filled up China's power industry this
Blank.
