technical field

The utility model relates to the technical field of noise reduction and dust removal devices for transformers, in particular to a dust-proof and noise-reduction transformer.

Background technique

Transformer refers to a device that uses the principle of electromagnetic induction to change AC voltage, and its main components are primary coil, secondary coil and iron core. The main functions of the transformer are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc. Transformers are the basic equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, urban communities and other fields.

In order to ensure the safe use of the transformer, most transformers need to be installed in a cabinet at present, and grids for ventilation and heat dissipation are provided on the side walls of the cabinet. However, the transformer has the following problems when it dissipates heat through the grid:

1. Dust will enter the cabinet through the grid and be adsorbed on the electronic components of the transformer. Dust adhered to the electronic components will not only affect the heat dissipation of the electronic components, but may also cause short circuits and accidents.

2. The natural wind directly enters the cabinet through the grid, and lacks a guide device to guide it, which is not conducive to heat dissipation.

In addition, during the working process of the transformer, the mechanical vibration of the iron core and the winding coil will generate relatively large noise.

detailed description

Below in conjunction with accompanying drawing 1-5, the specific embodiment of the utility model is described in further detail.

Embodiment 1, the technical solution is that the deflector 4 can guide the natural wind that enters the cabinet 1 through the ventilation grid 3, so that the natural wind can directly blow to the transformer body 2, and the heat dissipation effect is better , the wind collecting plate 5 provided can gather the natural wind to avoid the loss of air volume; the dust entering the cabinet 1 through the ventilation grid 3 along with the natural wind will be absorbed by the electrostatic precipitating plate 6 to prevent the dust from adhering to the transformer body The electronic components on 2 cause harm; for the dust adhering to the electrostatic precipitator 6, it is necessary to start the driving device and the ash collecting device regularly to clean up the dust on the electrostatic precipitator 6, and the driving device can drive the cleaning rod to remove the static electricity. The dust on the dust removal plate 6 is pushed and scraped to both sides of the electrostatic precipitator plate 6, at this time, the dust loses the adsorption effect of the electrostatic precipitator plate 6 and falls off, and is collected by the dust collection device; the shock absorbing block 16 provided can weaken the transformer body 2 Mechanical vibration during work reduces noise.

Embodiment 2, on the basis of Embodiment 1, when the driving device drives the cleaning rod 7, the motor 10 works to drive the reciprocating screw to rotate, and the rotation of the reciprocating screw will drive the connecting plate 11 to move longitudinally along the slide bar 8 At the same time, the cleaning rod 7 will also move longitudinally reciprocatingly with the action of the connecting plate 11, and the cleaning rod 7 will break away from the edge of the fine electrostatic precipitator plate when it moves to the maximum stroke. The longitudinal reciprocating movement of the dust removal rod 7 will push and scrape the dust on the electrostatic precipitator plate 6. During this process, due to the adsorption effect of the fine electrostatic precipitator plate, the dust removal rod 7 will push the dust to gather on the edge of the fine electrostatic precipitator plate. , and the dust will not scatter randomly until the dust removal rod 7 pushes the dust away from the edge of the fine electrostatic precipitator. Small vacuum cleaner 14 collects.
