Description
Technical field:
The utility model belongs to the air-cooled technology field of high voltage converter.
Background technology:
At present, the type of cooling that high voltage converter is commonly used is mainly radiator air blast cooling, recirculated water cooling and heat pipe cooling etc.Because of the air blast cooling mode is simple, the complexity that condensation problem when not having water-cooled and heat-pipe radiator are provided with under the situation of determining suitable aeration structure, generally adopts the air blast cooling mode comparatively reasonable.Adopt the air blast cooling mode need when structure is provided with, consider heat dissipation wind channel.The setting of heat dissipation wind channel should be under the requirement that takes into full account the power cell heat radiation, the simple optimizing of should trying one's best.The high voltage converter of common many level series system is divided into power cell cabinet, transformer case, control cubicle from structure.The series connection air channel structure is adopted in power cell cabinet air channel usually.The series connection air channel is relative up and down by the radiator of each power cell, forms corresponding up and down air channel, and wind is entered by the bottom air inlet, flows along vertical air channel from the bottom to top, is extracted out by blower fan then, discharges through air outlet.Be characterized in forming the path of connecting by a plurality of power cells up and down, simple in structure, the air channel is vertical, and windage is little.Because air flows from top to bottom, the heat energy of absorbed power unit release causes top power cell and ambient windstream to have a narrow range of temperature successively, and radiating effect is poor, and work is stable inadequately, has influenced the overall work stability of high voltage converter.In addition; the air inlet that high voltage converter is commonly used is equipped with screen pack in cabinet door inboard; but because work on the spot environment reason; it is often cleaned and changed to cause screen pack to need; when cleaned and changed, must shut down and open the cabinet door and operate; it is cumbersome to operate, and influences the normal and continuous operation of high voltage converter.
The utility model content:
The purpose of this utility model provides a kind of ventilation and heat situation that can effectively improve in the power cell cabinet, cleans the air-cooling apparatus of the high voltage converter of filter screen under non-stop-machine situation.
To achieve these goals, the utility model comprises: cabinet, power cell, the unit air inlet, the cabinet door, filter screen, main return, the unit air outlet, blower fan, air outlet, the air channel, unit, open baffle plate soon, power cell is parallel to each other successively and is arranged in parallel in the air channel, unit that is fixed on cabinet inside, the front end in air channel, unit is the unit air inlet, the rear end in air channel, unit is the unit air outlet, main return is positioned at the termination of unit air outlet and is interconnected with each unit air outlet, the upper end of main return is an air outlet, blower fan is fixedly installed on the cabinet and is positioned at the front portion of air outlet, the cabinet door of air inlet front portion, unit is provided with opens baffle plate soon, is placed with filter screen in the baffle plate opening soon.
Like this, the distinguished and admirable unit air inlet that passes through behind strainer filtering enters in the air channel, unit, distinguished and admirable power cell to its inside is lowered the temperature and is flowed out by the unit air outlet, high temperature gas flow imports total air channel in the unit cabinet, extracted out by the blower fan that is fixed on the cabinet top then, and aeration-cooling effect is obvious.Because baffle plate is opened in the increase of unit air inlet place soon on the cabinet door; make high voltage converter under non-stop-machine situation, extract filter screen out; filter screen is cleaned; improved the integral heat sink effect of high voltage converter; improved the reliability of equipment; it is safer, convenient to change the cleaning filter screen, and has improved the operational efficiency of system.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is filter screen and mounting structure schematic diagram.
Embodiment:
As seen from Figure 1, Figure 2, the utility model comprises: cabinet 1, power cell 2, unit air inlet 3, cabinet door 4, filter screen 5, main return 6, unit air outlet 7, blower fan 8, air outlet 9, air channel, unit 10, open baffle plate 11 soon.Power cell 2 is parallel to each other successively and is arranged in parallel in the air channel, unit 10 that is fixed on cabinet inside, the front end in air channel, unit 10 is unit air inlets 3, the rear end in air channel, unit 10 is unit air outlets 7, main return 6 is positioned at the termination of unit air outlet 7 and is interconnected with each unit air outlet, the upper end of main return 6 is air outlets 9, and blower fan 8 is fixedly installed on the cabinet and is positioned at the front portion of air outlet 9.The cabinet door 4 of unit air inlet 3 front portions is provided with and opens baffle plate 11 soon, is placed with filter screen 5 in the baffle plate opening soon, and filter screen can be extracted out from opening in the baffle plate soon easily.Filter screen 5 is made of screen cover and filtering material, and screen cover adopts the grid screen cover can effectively reduce the air intake windage, screen material employing good permeability, the synthetic silk floss of novel filtration that toughness is high.The cabinet door of earlier filter screen 5 being packed into during installation will be opened baffle plate 11 tops then soon and fill in cabinet door upper shed groove place, gently push inward with have gentle hands immediately and open the baffle plate bottom soon, and downward translation is opened baffle plate soon and got final product when treating that the bottom enters in the cabinet door.
