Description
Technical field
The present invention relates to transmission & distribution electrical domain, in particular to a kind of substation's dedusting cooling device.
Background technique
Substation is the place for changing voltage.For electrical energy transportation that power plant is issued to farther away place, it is necessary to
Voltage is increased, high-voltage electricity is become, nearby voltage is reduced as needed again to user, substation is leaned in the work of this buck/boost
To complete.The capital equipment of substation is switch and transformer.Wherein switchgear includes breaker, and breaker generally uses six
Sulfur fluoride breaker, sulfur hexafluoride breaker are a kind of open circuits using sulfur hexafluoride gas as arc-extinguishing medium and dielectric
Device, wherein sulfur hexafluoride is a kind of toxic gas for being slightly soluble in water.
Transformer is even more to play the role of vital in substation, and due to the relationship of iron core and winding, transformer exists
Copper loss and iron loss are generated in operation, the loss of this two parts is completely converted into heat, make iron core and heating in winding, insulation ag(e)ing,
The temperature of winding is to guarantee transformer safety, operate normally when influencing the service life of transformer, therefore controlling transformer station high-voltage side bus
Vital task.Measuring transformer upper layer oil temperature is the main means for monitoring transformer winding temperature at present.At present on transformer
For the upper limit of layer oil temperature between 80~85 DEG C, the temperature rise of transformer winding must not exceed 55 DEG C.Summer temperature is high, substation's transformation
Device is chronically at oepration at full load state, and substation transformer leads to the decline of insulation performance because of aging in addition, causes to become
The upper layer oil temperature of station service transformer often exceeds 80 DEG C.
In order to guarantee the safe operation of transforming plant main transformer, it is necessary to be carried out to the transforming plant main transformer that upper layer oil temperature is more than 80 DEG C auxiliary
Help cooling.Chinese patent CN104319669B discloses a kind of substation with spray cooling device, including stores oil pit, is located at
The pebble layer above oil pit, and the ground floor above pebble layer, and the main transformer on ground floor top surface are stored,
The outer peripheral surface of main transformer is equipped with cooling fin, which further includes the mist cooling dress that a set of pair of cooling fin carries out mist cooling
It sets, which includes water source, pressure pump, water-supply-pipe, spray equipment and pressure pump control apparatus；Spray equipment includes
Horizontal spray tube and spray head, spray tube are fixed along the orientation of cooling fin on main transformer with main transformer in half eminence of main transformer,
Spray head is arranged successively along the axial direction of spray tube, and one piece of cooling fin on each spray head face main transformer, to cooling fin into
Row is spraying；Pressure pump is equipped with inlet opening and apopore, and the inlet opening of pressure pump connects water source, the first end connection of water-supply-pipe
The second end of the apopore of pressure pump, water-supply-pipe connects spray tube.
But cooled down using above scheme to transformer, due to directly rushing at cooling fin using water flow, water flow may
Enter distribution box during impact and causes security risk.
Summary of the invention
The invention is intended to provide a kind of substation's dedusting cooling device, to solve to wash away transformation case band with water in the prior art
The security risk come.
Substation's dedusting cooling device in this programme, including shell, upper cover, water inlet pipe and limit hole, in the shell
Portion is equipped with partition, and enclosure interior is divided into transformation chamber and cooling chamber by the partition, the partition include vertical clapboard and it is horizontal every
Plate, the horizontal baffle are the bent plate to lower recess, and there are the mortar joint for allowing dust to pass through, institutes between horizontal baffle and vertical clapboard
Water inlet pipe to be stated to be arranged above horizontal baffle, the inner wall for the intracavitary shell that cools down is scraped equipped with water, and the water, which is scraped, is equipped with connecting rod,
The connecting rod connects upper cover, and the shell is equipped with the water outlet scraped against water of upper cover when in the open state.
Using this programme substation's dedusting cooling device when, water inlet pipe is first connected to tap water, the intracavitary generation of transformation
Heat makes the water on horizontal baffle accelerate evaporation, heat is taken away during water evaporation, and the steam evaporated wraps air middle reaches
The dust swung avoids dust accretions from influencing the intracavitary heat dissipation of transformation, and vapor, which encounters inner walls and condenses into droplet, stays in shell
In vivo, the droplet condensed into slides downwards from limit hole along shell and is discharged, and when opening upper cover to overhauling in shell, opens
Opening upper cover makes connecting rod that water be driven to scrape and move upwards, and the droplet for staying in enclosure interior is scraped into water outlet.
Transformation chamber and cooling chamber separated with partition and avoids vapor and makes transformation intracavitary workpiece dampness oxidation, to lower recess
Horizontal baffle can fill more water compared to straight horizontal baffle so that the effect of evaporative heat loss is more preferable；The intracavitary dust of transformation
It can be adsorbed on workpiece to keep workpiece temperature reduction slack-off, it is right to enter cooling chamber from transformation chamber for part dust after setting mortar joint
It is taken away afterwards by vapor；The water inlet pipe above horizontal baffle, which is arranged in, to guide to water flow on horizontal baffle, the water then having more
It is discharged from limit hole, water can be made to be always maintained at and ambient temperature using the tap water of flowing compared to using water level detector this programme
Unanimously, to strengthen cooling effect.
Shell is divided into cooling chamber and transformation chamber by partition by this programme, adds water to make water by from transformation chamber in cooling chamber
Heat of vaporization, herein in connection with the dust in air while the vapor evaporated takes away heat, vapor encounter shell condensation
It at droplet, slides from shell and is discharged again from limit hole, when upper cover is opened, water, which is scraped, to be also capped the connecting rod of connection and take up and make
It obtains remaining droplet on shell to be discharged from water outlet, reaches the mesh to cool down under the premise of not utilizing current scour to transformation case
's.
Further, the water, which is scraped, is obliquely installed, and the water outlet scrapes lowest part against water.It is scraped compared to horizontally disposed water,
The water being obliquely installed scrapes the droplet that can be controlled and be scraped and flows to lowest part, is discharged hence into water outlet.
Further, the vertical clapboard is equipped with drainage trough, and the drainage trough has the condensate layer of storage condensed water.Phase
Than being not provided with the vertical clapboard of drainage trough when there is condensed water on vertical clapboard, condensed water flows into condensate layer storage along drainage trough
Hiding.
Further, the vertical clapboard can be removed from shell.It is cleaned after taking-up compared to the vertical clapboard that cannot be removed
It is simpler.
Further, the partition is made of waterproof heat-conducting insulation material.Heat Conduction Material is easier to pass the heat of transformation chamber
It is delivered to cooling chamber, partition waterproof then prevents the intracavitary moisture that cools down to enter transformation chamber, and partition can take moisture when in use, because
This prevents partition electrification using insulating materials to ensure that the safety of staff.
Further, the upper lid is equipped with venthole.It can be expelled directly out equipped with steam after venthole, enter from venthole
Dust be pulled away also with the steam emerged from venthole.
