Description
Technical field
The present invention relates to preassembled transformer station and outdoor box switching station technical field, more particularly to preassembled transformer station and
Labyrinth type dust control by ventilation shutter used in outdoor box switching station.
Background technology
Preassembled transformer station and its inner ventilation of switching station, the method for cooling and dust-proof Resolving probiems mainly have at this stage：
1. common shutter mode.
Result of ventilating heat dissipation effectively is served, is generally used in the area without dust storm.But high wind sandy land can not be completely cut off
Sand and dust, sand and dust under high wind conditions can constantly enter nacelle inside, have influence on internal switch cabinet component such as：Operating mechanism
Deng so that internal switch cabinet can not normal use.
2. Intelligent warming way system is equipped with hermetically sealed nacelle.
The program uses hermetically sealed body structure, then in the absence of sandy soil warehouse entry problem.Controlled using intelligent industrial air-conditioning
Humiture inside nacelle.The drawbacks of certain be present in it：1. cost is high；2. the ventilation of nacelle inner ventilation is not smooth, air is more muddy；
3. the performance requirement of pair intelligent industrial air-conditioning is high, once room temperature certainly will constantly rise inside the nacelle that breaks down, cause to set in cabin
It is standby can not normal use；4：The O＆M cost of overhaul is higher.
3. conventional blind adds filter screen to add blower fan.
Which can effectively play ventilation and heat effect, but can not effectively completely cut off sand and dust.Outside tiny sand and dust exist
Nacelle can be inhaled into by filter screen in the presence of blower fan, so as to have influence on internal unit.Filter screen easily blocks after long-play,
Once filter net jam first internal heat dissipating be obstructed temperature can constantly raise influence equipment normal operation；Second the blower fan longevity can be influenceed
Life.Filter screen, detection blower fan need to often be cleared up.
The content of the invention
The technical problems to be solved by the invention are for existing preassembled transformer station and its inner ventilation of switching station, drop
Deficiency present in the method for warm and dust-proof Resolving probiems and a kind of labyrinth type without accessory power supply, energy-conserving and environment-protective is provided and divulged information
Dust-proof shutter.
The technical problems to be solved by the invention can be achieved through the following technical solutions：
Labyrinth type dust control by ventilation shutter, including forms, the forms are internally provided with ventilating duct, in the forms

In a preferred embodiment of the invention, described first can withdraw-type filter screen and second can withdraw-type filter screen divide equally
For first can withdraw-type screen holder, second can withdraw-type screen holder and can be on withdraw-type screen holder installed in described first first
Stainless steel filtering net, installed in described second the second stainless steel filtering net that can be on withdraw-type screen holder.
In a preferred embodiment of the invention, first stainless steel filtering net be 100 mesh stainless steel filtering net, second
Stainless steel filtering net is the stainless steel filtering net of 200 mesh.
As a result of technical scheme as above, common shutter is further improved by the present invention, and ventilating duct is adopted
With labyrinth type ventilating duct, barrier plate is set on sand and dust direct of travel, to reduce blast, using Action of Gravity Field so that in the middle part of air
Bigger sand and dust are divided to fall on each layer layering barrier plate, barrier plate is designed to that 45° angle tilts down, and is deposited on barrier plate
Sand and dust finally drop to letting out for ventilating duct bottom and discharged on husky plate through sand discharging port.It is a small amount of thin by carry for labyrinth type ventilating duct
The wind of sand and dust enters in preassembled transformer station case after 2 layers of strainer filtering again, and fine sand dirt, which is substantially all, to be adhered on filter screen, filter
Net is divided into 2 pieces of 100 mesh and 200 mesh, and on screen holder, screen holder is removable open architecture for equal pressure welding, it is convenient to extract out so as to
Clean filter screen.
The present invention compared with prior art, has following features：
1. reduce ventilating system volume；
2. cancelling blower fan, using gravity-flow ventilation, avoid by force sucking the air with sand and dust inside nacelle；
3. improving conventional blind structure, solve sand and dust and enter easily inside nacelle from shutter gap with the wind；
4. solving conventional filter screen can not easily dismount, it is difficult to the problem of cleaning.
The ventilation and heat and sand prevention of the invention for solving prefabricated cabin and switching station under high temperature, high Sand Dust Environment well is asked
Topic, has the following advantages that：
1. easily manufactured, technological requirement is low；
2. simple in construction, function is notable, cost-effective；
3. without accessory power supply, energy-conserving and environment-protective.
4. O＆M cost is low, cleans, changes conveniently.
