Abstract
The utility model discloses a novel insulated rear end cap for a three-phase synchronous high-voltage generator and relates to the technical field of high-voltage generators. The novel insulated rear end cap comprises a disk, a bearing chamber, an insulation ring, bolts and insulation gaskets. The bearing chamber is arranged at the center of the disk, the insulation ring is arranged between the disk and the bearing chamber, and the insulation gaskets are fixedly mounted at two sides of the bearing chamber through the bolts. The novel insulated rear end cap is reasonable in structural design, simple to operate, easy to install, convenient to use, safe and reliable, can effectively prevents high-voltage generator from generating shaft current, and improves the service life of front and rear bearings of the generator.
Description
Technical field:
The utility model relates to a kind of novel three-phase synchronous high-voltage generator insulation rear end cap, belongs to high-voltage generator technical field.
Background technology:
The technology of existing elimination shaft current is to adopt rear end cap and insulation bearing to form, and eliminates shaft current and mainly relies on the outer ring tape insulation layer of insulation bearing to cut off the path between generator unit stator and rotor, and just not having axial current flows to rotor by bearing.The shortcoming of prior art be insulation bearing be two to three times of plain bearing price, the bearing used due to high-voltage generator is all larger, so cause production cost higher, simultaneously insulation bearing must be forbidden the insulating barrier of damaging in installation process, otherwise lose insulation function, to operation, bring difficulty, after there is damage, be difficult for finding simultaneously, if any damage bearing, just scrap and cannot re-use.
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of novel three-phase synchronous high-voltage generator insulation rear end cap.
Three-phase synchronous high-voltage generator insulation rear end cap of the present utility model, it comprises disc, bearing chamber, dead ring, bolt, insulating washer, the middle part of disc is provided with bearing chamber, and between disc and bearing chamber, pad is provided with dead ring, and insulating washer is mounted by means of bolts between the two sides of bearing chamber.
As preferably, described disc is the torus with reinforcement.
As preferably, described bearing chamber is the torus with step.
As preferably, described dead ring adopts multi-layer insulation to consist of ring type.
As preferably, described insulating washer designs for cirque structure.
The beneficial effects of the utility model: its reasonable in design, simple to operate, be easy to install, easy to use, safe and reliable, can effectively prevent the generation of high-voltage generator shaft current, improved the useful life of generator front and back bearings.
Accompanying drawing explanation:
For ease of explanation, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is right view of the present utility model;
Fig. 3 is structure schematic diagram of the present utility model.
1-disc; 2-bearing chamber; 3-dead ring; 4-bolt; 5-insulating washer.
Embodiment:
As shown in Figure 1, this embodiment is by the following technical solutions: it comprises disc 1, bearing chamber 2, dead ring 3, bolt 4, insulating washer 5, the middle part of disc 1 is provided with bearing chamber 2, and between disc 1 and bearing chamber 2, pad is provided with dead ring 3, and insulating washer 5 is fixedly mounted between the two sides of bearing chamber 2 by bolt 4.
Wherein, described disc 1 is the torus with reinforcement; Described bearing chamber 2 is the torus with step; Described dead ring 3 adopts multi-layer insulation to consist of ring type; Described insulating washer 5 designs for cirque structure.
This embodiment adopts the hot assembly technology of heating disc when assembling, operate relatively simple, and technique is relatively stable, because assembling process is all to have higher temperature, under hot, be coated with the processing of sealing and be heating and curing simultaneously, so the insulating properties of insulation rear end cap is very reliable, can not cause failure of insulation because of misoperation, even ressemble after having problem also can remove, only need to change dead ring, loss cost is little, when generator assembles, can not cause because of misoperation the damage of insulation.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
