Abstract
The utility model belongs the field of electrical equipment, and relates to an auxiliary ventilation device for a transformer station, in particular to an indoor dust-free ventilation device, comprising a box body, wherein the box body comprises a first cavity and a second cavity, inside the first cavity there is provided a filter bag, the back side of the first cavity is equipped with a stainless wire net, and inside the second cavity there are orderly equipped a centrifugal fan and a silencer from top to down. The indoor dust-free ventilation device, through using the combination of the filter bag, the centrifugal fan and the silencer, can cooperatively control the supplement of new indoor dust-free air, and simultaneously stop the dust in air out of the filter bag; and dust-free air enters into an indoor environment to enable the air inside the transformer station room to be clean and dust-free, thereby improving the integrated environment, prolonging the service life of the electrical equipment, and greatly reducing the maintenance rate of the electrical equipment.
Description
Technical field
The utility model belongs to the electric equipment field, relates 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 dust can corrode electric equipment, even make electronic devices and components malfunctioning, and this has just buried potential faults, transformer station's electrical control cubicles are controlled malfunctioning, produce misoperation, have affected the normal operation of transformer station's circuit.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, ingenious, rational indoor dust-free ventilation unit is provided, and this device can filter air, makes air enter transformer station after dedusting indoor again.
The technical scheme that provides according to the utility model: 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 further improvement of the utility model, described the first cavity is positioned on the left of the second cavity.
As further improvement of the utility model, described filter bag is covered with the first cavity from top to bottom, and its cross section is wavy.
As further improvement of the utility model, 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 utility model compared with prior art, advantage is: the utility model 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 air is blocked in outside filter bag, dust-free air enters indoor, thereby makes indoor with fresh air dustless of transformer station, has improved integrated environment, extend the useful life of electric equipment, greatly reduced the maintenance rate of electric equipment.
