Description
Technical Field
The utility model relates to the field of frequency converters, in particular to an air-circulated dust-free frequency converter.
Background
In order to enable the high-voltage frequency converter to stably operate for a long time, the temperature of an operating environment is required to be between-5 and 40 ℃ generally, the dust content in the operating environment is also lower than 950ppm, the existing heat dissipation mode of the high-voltage frequency converter comprises air cooling heat dissipation, circulating water heat dissipation and the like, an air inlet and an air outlet of the air cooling heat dissipation are usually arranged indoors, the temperature in a power distribution room cannot be reduced, the temperature of the frequency converter is difficult to reduce, the air inlet and the air outlet are arranged indoors, the dust content in the room is also high, and the dust enters the frequency converter along with air during the air cooling heat dissipation, so that the frequency converter is easy to damage, and therefore improvement is still needed.
Disclosure of utility model
The utility model aims to solve the problems, and provides an air-circulated dust-free frequency converter which comprises a frequency converter box body, wherein a first air inlet plate and a second air inlet plate are arranged in the frequency converter box body at intervals, a plurality of air inlet holes are formed in the first air inlet plate and the second air inlet plate, a first fan and a second fan are arranged on the frequency converter box body, an air inlet pipe is connected to the first fan, a filter screen is arranged at an air inlet of the air inlet pipe, and an air outlet pipe is connected to the second fan.
Preferably, the air inlet holes of the first air inlet plate and the air inlet holes of the second air inlet plate are arranged in a staggered mode.
Preferably, the nozzles of the air inlet pipe and the air outlet pipe extend to the outside of the wall body.
The beneficial effects of the utility model are as follows: the utility model has reasonable structural design and convenient use, on one hand, the air in the box body of the frequency converter can realize circulation, the over-high temperature of the frequency converter is avoided, and on the other hand, the circulated fresh air can be filtered, so that the dust content in the frequency converter is reduced.
Drawings
The utility model will now be described by way of example and with reference to the accompanying drawings in which:
FIG. 1 is a schematic view of the overall structure of the present utility model;
In the figure: 1. a frequency converter box; 2. a first air inlet plate; 3. a second air inlet plate; 4. an air inlet hole; 5. a second fan; 6. a first fan; 7. a wall body; 8. an air inlet pipe; 9. a filter screen; 10. and (5) an air outlet pipe.
Detailed Description
All of the features disclosed in this specification, or all of the steps in a method or process disclosed, may be combined in any combination, except for mutually exclusive features and/or steps.
Any feature of the present description may be replaced by alternative features serving the same or similar purpose, unless expressly stated otherwise. That is, each feature is one example only of a generic series of equivalent or similar features, unless expressly stated otherwise.
The utility model provides an air can circulate dustless converter as shown in fig. 1, includes converter box 1, the interval is provided with first air inlet plate 2 and second air inlet plate 3 in the converter box 1, all be provided with a plurality of fresh air inlet 4 on first air inlet plate 2 and the second air inlet plate 3, be provided with first fan 6 and second fan 5 on the converter box 1, be connected with air-supply line 8 on the first fan 6, air intake department of air-supply line 8 is provided with filter screen 9, be connected with out tuber pipe 10 on the second fan 5.
The air inlet holes 4 of the first air inlet plate 2 and the air inlet holes 4 of the second air inlet plate 3 are arranged in a staggered mode.
The orifices of the air inlet pipe 8 and the air outlet pipe 10 extend to the outside of the wall body 7.
The wind pressure generated by the first fan 6 is greater than the wind pressure generated by the second fan 5.
In the use, make air-supply line 8 inhale outdoor air through first fan 6 to with the air-supply line 1 is gone into to the air delivery that will inhale, after the air enters into in the converter box 1, the air can pass second air inlet plate 3 and the fresh air inlet 4 of first air inlet plate 2 in proper order, and simultaneously second fan 5 makes air-supply line 10 to the inside air extraction of converter box 1 and will take out the air discharge to the outdoor, realizes the air cycle in the converter box from this, thereby ensures that the temperature in the converter box 1 can not be too high.
The filter screen 9 is arranged to filter the air entering the air inlet pipe 8, so that the dust content carried by the air entering the frequency converter box body 1 is reduced; the mouth of pipe of air-supply line 8 and play tuber pipe 10 all extends to wall body 7 outsidely, on the one hand can improve distribution indoor air environment, on the other hand also can avoid indoor dust repeatability to inhale in converter box 1 when carrying out air cycle.
The air inlet holes 4 of the first air inlet plate 2 and the air inlet holes 4 of the second air inlet plate 3 are arranged in a staggered mode, so that the wind power of fresh air passing through the first air inlet plate 2 and the second air inlet plate 3 is more uniform.
The beneficial effects of the utility model are as follows: the utility model has reasonable structural design and convenient use, on one hand, the air in the box body of the frequency converter can realize circulation, the over-high temperature of the frequency converter is avoided, and on the other hand, the circulated fresh air can be filtered, so that the dust content in the frequency converter is reduced.
The utility model is not limited to the specific embodiments described above. The utility model extends to any novel one, or any novel combination, of the features disclosed in this specification, as well as to any novel one, or any novel combination, of the steps of the method or process disclosed.
