Abstract
The invention provides a low-noise iron core reactor. The low-noise iron core reactor is composed of a bracket, a coil winding, an iron yoke, an iron core clamping plate and an iron core column, wherein the coil winding is assembled on the outer side of the iron core column. The low-noise iron core reactor is characterized in that the iron core column is formed by crossly overlapping an air pore plate and an iron core silicon steel sheet; the air pore plate is made of an vibration-absorption epoxy plate material; the air pore plate and the iron core silicon steel sheet are stuck through an epoxy binding agent which is cured at a room temperature to form a whole body structure. The low-noise iron core reactor has a simple structure, low production cost and simple process, is convenient to use and has stable performances; the noises of an iron core of the reactor can be effectively reduced, and the low-noise iron core reactor can be widely applied to the technical field of the reactors.
Description
Technical field:
The present invention relates to a kind of reactor technology, particularly relate to a kind of low noise iron core reactor technical field.
Background technology:
The noise of electric equipment is the technical indicator that can not be ignored, and reactor is no exception, particularly iron core reactor.Iron-core reactor is generally arranged on indoor, or the place that population is relatively dense, such as, in residential building community and the basement etc. of skyscraper, is strict, reduces its noise and be very important the requirement of products noise.National standard has clear and definite regulation to noise, and iron core series reactor noise is 70dB, and noise of arc suppression coil is 78dB, and shunt reactor noise is 80dB, has also all done corresponding regulation to the noise objective of other type reactor.The perfection of noise problem solves, and will be conducive to the self-growth of product, be also the process of product self-perfection.
At present, existing reactor with T-shaped core is made up of support, coil windings, iron yoke, iron core clamping plate, iron core stem stem, and coil windings is assemblied in outside iron core stem stem, and wherein iron core stem for reactor is folded by iron core silicon-steel sheet and air gap flaggy and formed.The noise that reactor produces to cause by the variation of magnetic flux in magnetic circuit mainly due to stacked silicon steel sheet and air gap plate and attracts or stress that magnetostriction produces, and generation is vibrated or mutual collision is caused.In order to reduce stacked silicon steel sheet and air gap plate changes the attraction or magnetostrictive stress that cause by magnetic flux in magnetic circuit, the general rapid-curing cutback glue that adopts comes bonding iron core silicon-steel sheet and air gap plate.But in practical operation, because glue adhesive strength is too low or to take man-hour too much because of needs baking-curing, when causing practical application, noise reduction is good or production cost is too high.
Summary of the invention:
The present invention, for solving prior art Problems existing, provides a kind of low noise iron core reactor.For achieving the above object, the present invention adopts following technical scheme:
The invention provides a kind of low noise iron core reactor.Low noise iron core reactor is made up of support, coil windings, iron yoke, iron core clamping plate, iron core stem stem.
In described low noise iron core reactor, coil windings is assemblied in outside iron core stem stem.
In described low noise iron core reactor, iron core stem stem is formed by iron core silicon-steel sheet and air gap plate intersecting.
In described low noise iron core reactor, air gap plate adopts damping epoxy plate material, and its structure runs through punching.
In described low noise iron core reactor, air gap plate and iron core silicon-steel sheet adopt the bonding integrally structure of ambient temperature curing epoxy adhesive, thus reduce stacked silicon steel sheet and air gap plate changes the attraction or magnetostrictive stress that cause by magnetic flux in magnetic circuit, and the vibration produced or mutually collision cause noise.
The advantage that the present invention has and good effect are:
1. the invention provides a kind of low noise iron core reactor, compared with existing iron core reactor, its iron core stem stem upper core silicon steel sheet have employed the bonding integrally structure of ambient temperature curing epoxy adhesive with the air gap plate of punching.Adopt this technical scheme, decrease stacked silicon steel sheet and air gap plate changes the attraction or magnetostrictive stress that cause by magnetic flux in magnetic circuit, reduce and produce vibration and collision mutually, effectively reduce the iron core noise of reactor.
2. to have employed ambient temperature curing epoxy adhesive namely curable at normal temperatures for the air gap plate of iron core silicon-steel sheet of the present invention and punching, reduces technique, reduces production cost.
3. air gap plate of the present invention adopts damping epoxy plate material, can effectively damping, reduction noise.
4. structure of the present invention is simple, and easy to use, stable performance, process operability is good, and production hour is short, and production technology cost is low, can be widely used in dry reactor technical field.

Reference numeral in each figure and the component names of correspondence as follows:
Wherein: 1 is support, 2 is coil windings, and 3 is iron yoke, and 4 is iron core clamping plate, and 5 is iron core stem stem, and 6 is iron core silicon-steel sheet, and 7 is air gap plate.
Embodiment:
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As depicted in figs. 1 and 2, low noise iron core reactor is made up of support 1, coil windings 2, iron yoke 3, iron core clamping plate 4, iron core stem stem 5, and coil windings 2 is assemblied in outside iron core stem stem 5.
The invention provides low noise iron core reactor.Iron core stem stem 5 is formed by iron core silicon-steel sheet 6 and air gap plate 7 intersecting; Described air gap plate 7 adopts damping epoxy plate material, and its structure runs through punching; Iron core silicon-steel sheet 6 adopts the bonding integrally structure of ambient temperature curing epoxy adhesive with the air gap plate 7 of punching; Thus reduce stacked iron core silicon-steel sheet 6 and change with air gap plate 7 attraction or magnetostrictive stress that cause by magnetic flux in magnetic circuit, and the vibration produced or mutual collision cause noise.
In the present invention, to have employed epoxy adhesive namely curable at normal temperatures for iron core silicon-steel sheet 6 and the air gap plate 7 of punching, reduces technique, reduce production cost.
The elaboration of book according to the above description, those skilled in the art in the invention can also carry out suitable change and amendment to above-mentioned execution mode.Therefore, the present invention is not limited to embodiment disclosed and described above, also should fall in the protection range of claim of the present invention modifications and changes more of the present invention.In addition, although employ some specific terms in this specification, these terms just for convenience of description.
