Description

Low-noise iron core reactor

Technical Field

The utility model relates to a reactor manufacturing technology specifically is a low noise iron core reactor.

Background

The existing reactor iron core and coil are in a split structure, the iron core column is composed of a discus and a gap, when the coil is electrified, the discus gap vibrates to cause great noise, the industry standard is limited by a specified noise value, and even the product which can not reach the noise standard is often used. Some reactors have noise meeting the standard, but the vibration force is large, the cabinet body is driven to shake after installation, and the noise is indirectly large, so that the whole noise of the complete equipment exceeds the standard, the electric power is large, screws are easy to loosen, the temperature is increased, the service life is influenced, and the reliability of operation is poor.

Meanwhile, noise is also an environmental pollution, and influences on human health in different degrees can be generated in the noise-polluted environment for a long time, so that the production of the low-noise iron core reactor is very necessary.

SUMMERY OF THE UTILITY MODEL

To iron core reactor noise pollution influence environment among the prior art, poor stability etc. not enough, the to-be-solved problem of the utility model is to provide a vibrating force is little, can not cause the whole bolt of complete sets not hard up low noise iron core reactor.

In order to solve the technical problem, the utility model discloses a technical scheme is:

The utility model relates to a low noise iron core reactor, including iron core post and coil, the coil adopts the resin casting to be an overall structure with the iron core, has resin layer, air flue and net cloth between iron core and the coil in proper order, also is equipped with net cloth outside the outer coil.

The coil is 2 ~ 4 layers, is equipped with the DMD membrane between the layer, and both ends and skin all adopt resin package about the coil.

The utility model has the following beneficial effects and advantages:

1. The utility model discloses low noise reactor iron core post discus and clearance and the whole vacuum of coil are pour integratively, have the air flue heat dissipation between coil and the iron core, greatly reduced the product noise, require a lot of less than the standard, not near the front almost noiselessness.

2. The utility model discloses there is not any noise when moving under the rated current, and the electrodynamic force is also extremely low, and 0.27 is chooseed for use to reactor blade of silicon steel specification, low-loss, low magnetic density, and insulating properties is very excellent, and the operation is stable, and dynamic thermal stability is good.

3. The utility model discloses the cost is not upper and lower than traditional reactor cost, and the reliability is higher, and the vibrational force is little, can not cause the whole bolt of complete sets not hard up, can reduce the incidence of accident.

Detailed Description

The invention will be further explained with reference to the drawings attached to the specification.

As shown in fig. 3, the utility model relates to a low noise iron core reactor, including 1 post of iron core and coil 10, coil 10 adopts resin 5 pouring to be an overall structure with iron core 1, has resin layer, air flue 6 and net cloth 7 between iron core 1 and the coil 10 in proper order, and outer coil 10 also is equipped with net cloth 7 outward and as the interlayer insulation.

The coil 10 is 2 ~ 4 layers, and the layer is equipped with DMD membrane 8 and insulates, and both ends and the skin all adopt resin 5 to cast encapsulation about the coil 10.

In this embodiment, a three-phase reactor is taken as an example, as shown in fig. 1A to 1B and 2, each core limb is a laminated structure of a plurality of discuses, and each discus is made of a low-loss and low-magnetic-density silicon steel sheet with a specification of 0.27. When pouring, the three-phase iron core and the coil are placed according to the process requirements, a gap is reserved between each iron core column and the coil to be used as a heat dissipation air channel between the coil 10 and the iron core 1, and then the mold cylinder is sleeved outside each phase of coil to carry out resin casting, so that the resin is cured into a round shape. The process is matched with the design of the iron core and the coil, the number and the thickness of gaps are reduced as much as possible, the pouring effect is better, the noise is low, the electric power is low, and the cabinet body cannot vibrate and enlarge the noise.

The utility model discloses the reliability is higher, and the vibrational force is little, can not cause the whole bolt of complete sets not hard up, can reduce the incidence of accident.

In practice, the utility model discloses an appearance inspection, winding direct current resistance survey, insulation resistance survey, reactance value survey, loss survey, power frequency withstand voltage test, winding interturn insulation test, noise test, temperature rise test and partial discharge test, the data that obtain all show, the utility model discloses an audit for the experiment reaches the qualification standard.
