Abstract
The invention belongs to the field of electrical equipment, relates to an auxiliary ventilating device of a transformer substation, and particularly relates to an indoor dustless ventilator. The indoor dustless ventilator comprises a box body, wherein the box body comprises a first cavity and a second cavity; a filter bag is arranged inside the first cavity; a stainless wire mesh is arranged at the back side of the first cavity, and a centrifugal fan and a silencer are orderly arranged inside the second cavity from the top to the bottom. The indoor dustless ventilator can coordinate and control supply of indoor dustless fresh air by combination of the filter bag, the centrifugal fan and the silencer; meanwhile, the dust in the air is stopped out of the filter bag, and the dustless air enters the room, thus, the indoor air in the transformer substation is fresh and dustless; the whole environment is improved; the service life of electric equipment is prolonged, and the maintenance rate of the electric equipment is greatly reduced.
Description
Technical field
The invention belongs to the electric equipment field, relate to a kind of secondary ventilation equipment of transformer station, specifically the indoor dust-free ventilation unit.
Background technology
At present, the indoor axial flow blower that generally adopts of transformer station ventilates, and outdoor air is not having directly to enter under the state of dust suppression indoor, causes the indoor electric equipment of transformer station and electronic devices and components that serious fouling phenomenon occured after the work several years.More seriously, the acidic materials in the dust can corrode electric equipment, even make electronic devices and components malfunctioning, and this has just buried potential faults, may make transformer station's electrical control cubicles control malfunctioning, produce misoperation, have affected the normal operation of transformer station's circuit.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of indoor dust-free ventilation unit simple in structure, ingenious, rational is provided, this device can filter air, so that air enters transformer station again after dedusting indoor.
According to technical scheme provided by the invention: the indoor dust-free ventilation unit, comprise casing, be characterised in that: described casing comprises the first cavity and the second cavity, and filter bag is installed in described the first cavity, stainless steel cloth is installed at the described first cavity back side; Centrifugal blower, muffler are installed in described the second cavity from top to bottom successively.
As a further improvement on the present invention, described the first cavity is positioned at the second cavity left side.
As a further improvement on the present invention, described filter bag is covered with the first cavity from top to bottom, and its cross section is wavy.
As a further improvement on the present invention, described silencing end is with arc transition, the be tightly connected air outlet of centrifugal blower of its upper end, and the lower end is fixed on the sidewall of the second cavity.
The present invention compared with prior art, advantage is: the present invention utilizes the combination of filter bag, centrifugal blower and muffler, can coordinate to control replenishing of the new wind of indoor dust-free, simultaneously dust in the air is blocked in outside the filter bag, dust-free air enters indoor, thereby makes indoor with fresh air dustless of transformer station, has improved integrated environment, prolong the useful life of electric equipment, greatly reduced the maintenance rate of electric equipment.

Fig. 3 is the casing rearview.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1 and Figure 2, described indoor dust-free ventilation unit comprises filter bag 1, casing 2, centrifugal blower 3, muffler 4, stainless steel cloth 5, the first cavity 6, the second cavity 7.
As shown in Figure 1 and Figure 2, the indoor dust-free ventilation unit comprises casing 2, and described casing (2) comprises the first cavity 6 and the second cavity 7, described the first cavity 6 interior installation filter bags 1, and stainless steel cloth 5 is installed at described the first cavity 6 back sides; In described the second cavity 7 centrifugal blower 3, muffler 4 are installed successively from top to bottom.
Described the first cavity 6 is positioned at the second cavity 7 left sides.
Described filter bag 1 is covered with the first cavity 6 from top to bottom, and its cross section is wavy.
Described muffler 4 ends are with arc transition, the be tightly connected air outlet of centrifugal blower 3 of its upper end, and the lower end is fixed on the sidewall of the second cavity 7.
The present invention utilizes the combination of filter bag, centrifugal blower and muffler, can coordinate to control replenishing of the new wind of indoor dust-free, simultaneously dust in the air is blocked in outside the filter bag, dust-free air enters indoor, thereby make indoor with fresh air dustless of transformer station, improve integrated environment, prolonged the useful life of electric equipment, greatly reduced the maintenance rate of electric equipment.
