Abstract
A kind of speed-sensitive switch of opening and closing fast, relate to technical field of electricity, comprise moving iron core and can with the static iron core of moving iron core adhesive, described static iron core one side is provided with magnet, described moving iron core periphery is provided with coil, after described coil electricity, produce high frequency magnetic field and make iron core drive static iron core and magnet attraction, after coil blackout, magnetic field disappears, and described moving iron core separates with static iron core.The utility model is simple in structure, and modern design utilizes electromagnetic principle to realize switch deciliter, reaches quick opening and closing, and serviceability is good.
Description
Technical field
The utility model relates to technical field of electricity, is specifically related to a kind of speed-sensitive switch of opening and closing fast.
Background technology
At present, field of switches at home and abroad, the existing switch deciliter time, cannot be fast in the time that electrical network produces fault deciliter at least all more than a few tens of milliseconds, and the person and electric equipment are suffered damage.Even under normal circumstances, general switch, because deciliter time can produce slowly switching overvoltage and shove, also can cause the infringement of electric equipment.
Utility model content
It is a kind of stable that technical problem to be solved in the utility model is to provide, the speed-sensitive switch of opening and closing fast that practical application effect is good.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of speed-sensitive switch of opening and closing fast, comprise moving iron core and can with the static iron core of moving iron core adhesive, described static iron core one side is provided with magnet, described moving iron core periphery is provided with coil, after described coil electricity, producing high frequency magnetic field makes iron core drive static iron core and magnet attraction, after coil blackout, magnetic field disappears, and described moving iron core separates with static iron core.
The beneficial effects of the utility model are: the utility model is simple in structure, and modern design utilizes electromagnetic principle to realize switch deciliter, reaches quick opening and closing, and serviceability is good.
Brief description of the drawings
Fig. 1 is the utility model principle schematic.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of speed-sensitive switch of opening and closing fast, comprise moving iron core 1 and can with the static iron core 2 of moving iron core 1 adhesive, static iron core 2 one sides are provided with magnet 3, moving iron core 1 periphery is provided with coil 4, produces high frequency magnetic field and make iron core 1 drive static iron core 2 and magnet 3 adhesives after coil 4 energisings, and after coil 4 power-off, magnetic field disappears, moving iron core 1 separates with static iron core 2, realizes power-off.
More than show and described general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
