Description
Technical field
The utility model belongs to contactor construction design field, is specifically related to a kind of rapid box vacuum contactor.
Background technology
In current power system, high, in, what lv contactor and breaker used is all electromagnetic type divide-shut brake, the speed of electromagnetism divide-shut brake mainly leans on the volume size of coil and magnet to realize, because vacuum contact carrys out arc extinguishing by vacuum tube, vacuum tube is made up of self-closing power and contact stage clip, the vacuum contactor that conventional electric power uses, contact stage clip and separating brake reaction spring is had to be mentality of designing in design, so design coil and magnet volume larger, vacuum tube could be shifted onto closing position, because the power promoted is greater than the self-closing power of vacuum tube and overtravel spring force also has reaction spring power summation.The larger closing time of coil is longer, and because electromagnet coil has the existence of inductance, the size of inductance concerns the speed of contact closing time.
The conventional contact of domestic market can not meet the novel industries such as present photovoltaic solar, wind-power electricity generation.Because these novel generatings are carried out under not power-off when being connected to the grid.Contactor is exactly the original paper of wherein grid-connected key, so require high to contactor closing time, must control at below 3ms, conventional contact cannot realize.
Utility model content
The restriction that the utility model is subject in novel industry application for conventional contact on market, proposes a kind of quick box permanent magnetism one pole vacuum contactor.
The technical solution adopted in the utility model is as follows:
A kind of quick box permanent magnetism one pole vacuum contactor, comprise casing, vacuum switch tube, the permanent magnet mechanism placed side by side is provided with in described casing, it is characterized in that: below described vacuum switch tube, be provided with overtravel spring, described overtravel spring one end is fixedly mounted on bottom half, the moved end connecting lever of below and vacuum switch tube that the other end is positioned at vacuum switch tube does not contact, described permanent magnet mechanism comprises permanent magnet, electromagnet and dynamic iron core, below described dynamic iron core, back-moving spring is housed, the other end of described back-moving spring is fixedly mounted on bottom half; Also comprise insulation connecting lever, described insulation connecting lever is positioned at vacuum switch tube and contacts back-moving spring and overtravel spring with permanent magnet mechanism downward vertical, its one end is fixedly mounted on the sidewall of casing, and the other end is fixedly connected with dynamic iron core lower end, and described insulation connecting lever and overtravel spring are for energy storage of closing a floodgate; The top of described permanent magnet mechanism is also provided with manual brake separating assembly; Described manual brake separating assembly comprise be connected to permanent magnet mechanism upper end connecting lever, the other end of described connecting lever is provided with manual brake separating button, and described manual brake separating button is arranged on casing top; Also comprise the conductive plate going deep into casing, described conductive plate connects vacuum switch tube moving contact by wire in casing.
Described overtravel spring is butterfly spring, and pressure stability is easy to adjust, provides combined floodgate power.The permanent magnet of described permanent magnet mechanism keeps.
By the arm of force ratio of described connecting lever, make the manual operation dynamics that needs less, and then make electromagnet stroke also little, easily control electromagnet and promote dynamic iron core and to have threaded off separating brake action.
The utility model is operationally: the main self-closing power of vacuum switch tube and the overtravel spring of using carries out energy storage when manual brake separating, switch on power, coil in permanent magnet jar carries out promoting dynamic iron core after excitation and arrives closing position, and at this moment coil have been cut off the electricity supply combined floodgate task by auxiliary contact.
The beneficial effects of the utility model are embodied in:
The utility model is by adopting manual brake separating assembly separating brake, and overtravel spring directly closes a floodgate.During separating brake, manual operation manual brake separating assembly, the dynamic iron core of permanent magnet mechanism props up overtravel spring by insulation connecting lever, realizes separating brake; During combined floodgate, the dynamic iron core of permanent magnet mechanism is threaded off, overtravel spring acts directly on the moving contact of vacuum switch tube, directly close a floodgate under the negative pressure of vacuum switch tube and the effect of overtravel spring, add the pressure of vacuum switch tube moving contact, overcome its spring problem, breach the problem of contactor and breaker spring in the past.Also substantially increase closing time, within making it reach 1ms, whole closing time reaches below 3ms, for solar energy, wind-electricity integration solve a great problem, has also filled up this blank of China's power industry.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
