Its closure well and do not need plus the sliding ring of fan cover.
Description
Technical field
The utility model relates to a kind of parts of generator, particularly relates to the slip ring cover that a kind of degree of protection is high.
Background technology
Winding rotor motor conventional in current production is divided into interior sliding ring type and outer sliding ring type two kinds.Convenient owing to changing brush, carbon dust can not enter motor internal, and outer sliding ring type winding rotor motor is the most common.Common outer slip ring motor, as YRKK type and YRKS type, motor body degree of protection can reach IP54, but the degree of protection of slip ring cover part can only reach IP23.This can meet instructions for use in common occasion, but in the occasion of bad environments, as cement plant load of mill occasion, on-the-spot dust granules thing is numerous, and doping is with air, slip ring cover inside can be entered with the cooling air of slip ring, fall on slip ring, accelerate the wearing and tearing of carbon brush, if containing conductive materials such as coal dusts in dust, dust can cause rotor phase fault and ground connection, harm production safety.
For slip ring, usually can adopt the type of cooling of IC611, except the primary cooler fan of motor configuration, also needing at the outer cooling fan of outfit slip ring is that slip ring cools, and installation is inconvenient and volume is large.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of closure good and does not need the slip ring cover of additional fans.
The slip ring cover that a kind of degree of protection that the utility model provides is high, comprises slip ring cover main body, slip ring cooler, and described slip ring cover main body is the square box structure of welding, inner placement slip ring main body, its front end is end cap, and rear end is connected with a protuberance, and described protuberance is Flange joint mechanism; The rotating shaft of slip ring is provided with labyrinth ring, on the rear end face of described labyrinth ring slip ring cover main body; Described slip ring cooler is arranged on above slip ring cover main body, forms inner and outer air paths between cooler and slip ring, for slip ring cools.
Described cooler comprises external fan, and inner and outer air paths is respectively, by wind path in the coaxial fans drive be contained on slip ring, and the outer ventilation circuit driven by cooler of electric motor external fan.
In the bottom of described slip ring cover main body, be provided with electric heater, it is arranged on below slip ring.
In two sides of slip ring cover main body, be equipped with outlet bucket.
The utility model adopts above technical scheme compared with prior art, has following technique effect:
1, the material composition end cap that slip ring cover employing airtight performance is high, and collocation labyrinth ring, become better sealing structure, effectively prevent the foreign matter of external environment condition to enter, ensure cleaning inside and security of operation;
2, cooling device make use of the coaxial fan of slip ring, ingenious utilization principle of negative pressure, and utilize primary cooler external fan to drive slip ring cooler outer ventilation circuit in the negative pressure that afterbody is formed, slip ring cooler does not need separately to establish external fan;
3, be provided with outlet bucket in the both sides of slip ring cover, for the wiring of the rotor wiring of motor, according to the demand of different model device, can occur towards different directions, connect up reasonable, attractive in appearance and facilitate;
4, also electric heater is housed in slip ring cover, opens when motor stalling, prevent condensate from producing.
Accompanying drawing explanation
Below with reference to accompanying drawing, the utility model is described in further detail:
Fig. 1 is slip ring cover structural representation;
Fig. 2 is the end view of slip ring cover structure;
Wherein, 1-slip ring cover main body, 2-adpting flange, 3-labyrinth ring, 4-slip ring cooler, 5-end cap, 6-outlet bucket, 7-electric heater.
Embodiment
The utility model provides the slip ring cover that a kind of degree of protection is high, and for making the purpose of this utility model, technical scheme and effect clearly, clearly, and further describe the utility model with reference to accompanying drawing examples.Should be appreciated that concrete enforcement described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Be the slip ring cover that a kind of degree of protection of the present utility model is high as shown in Figure 1 and Figure 2, comprise slip ring cover main body 1, slip ring cooler 4, described slip ring cover main body 1 is the square box structure of welding, inner placement slip ring main body, its front end is end cap 5, rear end is connected with a protuberance, and described protuberance is Flange joint 2 mechanism; The rotating shaft of slip ring is provided with labyrinth ring 3, and described labyrinth ring 3 is connected on the rear end face of slip ring cover main body 1; Described slip ring cooler 4 is arranged on above slip ring cover main body 1, forms inner and outer air paths between slip ring cooler 4 and slip ring, for slip ring cools.
Above-mentioned cooler comprises external fan, and inner and outer air paths comprises, and interior wind path is by the coaxial fans drive be contained on slip ring, and outer ventilation circuit is driven by cooler of electric motor external fan; In the bottom of slip ring cover main body 1, arrange and have a heater 7, it is arranged on below slip ring; And in two sides of slip ring cover main body 1, be equipped with outlet bucket 6.
The slip ring cover all cover plates in surface that the utility model provides and the sealing of inspection hole all reach IP54 rank; Slip ring cover adopts independent cooler, ventilating duct and motor primary cooler radiating tube air inlet distance 15 ~ 20mm on cooler, when motor runs, primary cooler air intake vent place produces negative pressure, under atmospheric pressure, air enters from the right side air inlet of slip ring cooler, take away in slip ring cover after heat, flow out from left side air outlet and enter motor primary cooler.
Rotor windings binding post is arranged on slip ring cover inside, and all reserved outlet bucket 6 in slip ring cover both sides, user selects to occur direction as required.
Above embodiment is only and technological thought of the present utility model is described; protection range of the present utility model can not be limited with this; every technological thought according to the utility model proposes, any change that technical scheme basis is done, all falls within the utility model protection range.
