Abstract

The utility model discloses a novel respirator for a transformer. The respirator comprises a shell, silica gel particles, an air suction pipe, an oil cup, a tray, tray round vertical plates and ventilation cloth. The air suction pipe is connected into the bottom of the shell from the top outside the shell, an air inlet in the lower end of the air suction pipe is a horn mouth, the tray is installed inside the shell and composed of four fixed steel bars and a fixed round ring, the tray round vertical plates are installed on the fixed steel bars, the ventilation cloth covers the bottom of the tray, and the included angle between the plane where the tray is located and a horizontal plane is 30 degrees. Through the inclined tray, air can diffuse all around along the angle of the tray in the diffusion process, and therefore the silica gel particles in every corner can fully make contact with air, and practicality efficiency of silica gel is improved. Due to the adoption of the layered design, ineffective silica gel particles on the lower layer and recyclable silica gel particles on the upper layer are convenient to sort when the silica gel particles are replaced, and material cost is saved.

Description

Novel transformer respirator

Technical field

The utility model relates to a kind of transformer accessory, relates in particular to a kind of novel transformer respirator.

Background technology

Respirator for transformer Main Function is in transformer running, guarantees the drying property of transformer and extraneous exchanging gas, prevent that steam from entering in transformer oil, thereby the potential safety hazard of preventing is avoided accident.Existing respirator for transformer is generally barreled airtight container, is placed with dry silica gel particle in airtight container.Because first air need to filter through transformer oil for the first time, so enter the air of internal tank all with a small amount of transformer oil, these air can be by silica gel absorption during by silica gel particle, the silica gel that has sucked transformer oil can be contaminated, thereby can not reuse, and be also difficult for contaminated silica gel and recyclable sorting out when maintenance, thereby cause silica gel in respirator all to be changed, shine into waste.Existing transformer breath device gas is skewness often, and the utilance of silica gel is often not high, inefficiency.

Utility model content

The purpose of this utility model is just to provide in order to address the above problem a kind of novel transformer respirator of high hydroscopicity.

The utility model is achieved through the following technical solutions above-mentioned purpose:

Novel transformer respirator described in the utility model, comprise housing, silica gel particle, air intake duct, lubricating cup, pallet, the circular riser of pallet and breather cloth, described air intake duct top from described housing passes into bottom, the air inlet of described air intake duct lower end is horn mouth, described horn mouth is positioned at described lubricating cup, described pallet is arranged on described enclosure interior, by four, fixedly steel bar and a clamping rings form described pallet, the circular riser of described pallet is arranged on described fixedly steel bar, the height of the circular riser of described pallet is 15mm, spacing between the circular riser of a plurality of described pallets is 30mm, described breather cloth is covered in described tray bottom, angle between described pallet place plane and horizontal plane is 30 degree.The circular riser of described pallet on a described pallet and this pallet forms a tray unit, and described respirator comprises a plurality of described tray units that are arranged above and below.Described breather cloth is nonwoven fabrics.

The beneficial effects of the utility model are:

Respirator for transformer described in the utility model is by the pallet tilting, make the distribution of gas of suction even, gas can spread to surrounding along the angle of pallet in diffusion process, and the silica gel particle that makes every nook and cranny is ingress of air fully, the practical efficiency of raising silica gel.When changing silica gel particle, owing to adopting layer-stepping design, change convenient and swift.Because inefficacy silica gel, in lower floor, so upper strata dry silica gel can continue to use, has been saved material cost.

Fig. 1 is the utility model respirator for transformer internal structure schematic diagram;

Fig. 2 is the plan structure schematic diagram of pallet described in the utility model;

Fig. 3 is the syndeton schematic diagram between tray unit described in the utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As Fig. 1, Fig. 2, shown in Fig. 3, the air intake duct 5 of the utility model respirator for transformer top from described housing 1 passes into bottom, the air inlet of air intake duct 5 lower ends is horn mouth 6, horn mouth 6 is positioned at lubricating cup 7, pallet 2 is arranged on housing 1 inside, by four, fixedly steel bar 9 and a clamping rings 10 form pallet 2, the circular riser 3 of pallet is arranged on fixedly on steel bar 9, the height of the circular riser 3 of pallet is 15mm, spacing between the circular riser 3 of a plurality of pallets is 30mm, breather cloth 11 is covered in pallet 2 bottoms, angle between pallet 2 place planes and horizontal plane is 30 degree.The circular riser 3 of pallet on a pallet 2 and this pallet forms a tray unit, and respirator comprises a plurality of tray units that are arranged above and below, and silica gel particle 4 is evenly positioned on tray unit.Breather cloth 11 is nonwoven fabrics.Air arrives horn mouth 6 by air intake duct 5, and air evenly spreads and comes at horn mouth 6, and the air of diffusion filters for the first time in lubricating cup 7, then enters 2 layers, pallet.Air is along the upwards diffusion of plane at pallet 2 places, and the silica gel particle that in diffusion process, air is uniformly distributed, contacts is many, and airborne moisture absorption is high, under the filtration layer by layer of pallet 2, can guarantee the air dried and clean leaching.
