The electric reactor coil clearance forced air cooling device comprises a negative pressure fan, and is characterized in that the negative pressure fan is connected with an air outlet of an air-sucking cover, and air inlet of the air-sucking cover is arranged on an electric reactor coil in a sleeved mode. The electric reactor coil clearance forced air cooling device is low in cost, reasonable in structure, simple, delicate, easy to maintain and install, good in heat dissipation effect, and capable of meeting the requirements for cooling of operating electrical equipment.
Description
Technical field
The utility model belongs to electric cooling field, is specifically related to a kind of reactor winding gap forced air-cooling device.
Background technology
In electric power system, the leakage field in reactor winding gap is larger, during long-play, easily generate heat, and temperature rise is increased and can be made it lose insulation property by acceleration the aging of insulating material, and the lighter can shorten the useful life of reactor, and severe one can cause fire incident.The type of cooling that prior art adopts can not solve the cooling problem in reactor winding gap effectively.
Summary of the invention
The utility model has solved the deficiencies in the prior art, and a kind of reactor winding gap forced air-cooling device of with low cost, simple in structure, good heat dissipation effect is provided.
In order to solve the deficiencies in the prior art, the technical scheme that this practicality is adopted is: a kind of reactor winding gap forced air-cooling device, comprise negative-pressure air fan, it is characterized in that: described negative-pressure air fan is connected with the air-suction cover air outlet, and the air-suction cover air inlet is nested with on reactor winding.
Described negative-pressure air fan is connected by the insulation connecting tube with air-suction cover.
Described insulation connecting tube is L shaped bend pipe.
One end of described L shaped bend pipe is circular ports, and the other end is square calibre.
Described air-suction cover is the cover body with loop vent groove, be that air-suction cover forms integrally-built annular cover body by annular inner wall, annular outer wall and annular top cover, annular outer wall is provided with ventilating opening, ventilating opening communicates with ventilation slot and with the insulation connecting tube, is connected looping ventilation slot between annular inner wall and annular outer wall.
The method that the utility model adopts natural air cooling mode and air blast cooling mode to combine, reactor is implemented to the air cooling cooling effect, obviously promote cooling effect, utilize simultaneously the aerodynamic principle on basis, adopt the top air inducing mode, coordinate air motion from bottom to top, accelerate Air Flow and strengthen convection effects.The utility model is simple in structure, novel in design, the forced air-cooling of holding concurrently, rainproof, dustproof, prevent that pollution flashover, sunshade function are in one, and be easy to installation and maintenance.
The accompanying drawing explanation
Fig. 1 structural representation of the present utility model
1. negative-pressure air fan 2. air-suction cover air outlet 3. air-suction cover air inlet 4. collar extension air-suction covers 5. insulation tube connectors.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of reactor winding gap forced air-cooling device, comprise negative-pressure air fan 1, it is characterized in that: described negative-pressure air fan 1 is connected with air-suction cover air outlet 2, and air-suction cover air inlet 3 is nested with the top at reactor winding.
Described negative-pressure air fan is connected by insulation tube connector 5 with air-suction cover.
Described insulation tube connector 5 is L shaped bend pipe.
One end of described L shaped bend pipe is circular ports, and the other end is square calibre.
In order to prevent that air-flow from bringing conductor into, reactor winding is caused damage, the bottom of reactor winding is equipped with air filter.
Described air-suction cover is the cover body with loop vent groove, be that air-suction cover forms integrally-built annular air-suction cover by annular inner wall, annular outer wall and annular top cover, annular outer wall is provided with ventilating opening, ventilating opening communicates with ventilation slot and with the insulation connecting tube, is connected looping ventilation slot between annular inner wall and annular outer wall.
Operation principle of the present utility model is as follows: collar extension air-suction cover 4 and insulation tube connector 5 use one-body molded insulating glass steel to do, and can guarantee the normal operation of reactor in service.The air inlet 3 of collar extension air-suction cover 4 is nested with on the whole coil of reactor, and guarantees the tightness of collar extension and coil, and the air outlet 2 of collar extension air-suction cover is connected with insulation tube connector 5, and insulation tube connector 5 is connected on the inlet scoop of negative-pressure air fan 1.Start negative-pressure air fan 1, at this moment because collar extension air-suction cover 4, insulation tube connector 5 are combined tightly with whole coil, therefore between collar extension air-suction cover 4, insulation tube connector 5 and each winding space of reactor, form negative pressure state, between each winding space of reactor, produced powerful ventilating air, air velocity and cooling-down effect are proportional, have realized the forced air-cooling effect.Because dust in the air in the external world is more, the air filter device is installed in the gap of reactor winding downside, guarantees can use peace and quiet air when forced air-cooling.
The outer appearnce of collar extension air-suction cover 4 can prevent that like a cap rainwater or dust from directly entering the winding space of reactor, also possesses certain sunshade effect simultaneously.The hollow space of collar extension air-suction cover 4 is beneficial to the natural bulk storage of reactor heat.
