Out.It is the main dynamics equipment of power station production electric energy.
The output voltage of traditional small-capacity low-pressure hydrogenerator is 400V, and for the low pressure hydraulic generator of large capacity
Machine, output voltage is according to 400V, then generator terminal output electric current is bigger, and temperature is high-leveled and difficult to be handled in cooling, the items in power station
Construction cost is relatively high, and is unfavorable for the safe operation of unit.Therefore, in order to solve this problem, develop a kind of by hydraulic generator
The output voltage of machine is improved to 660V, and is imagined and carried out special construction design to the stator coil of hydrogenerator.
Summary of the invention
In order to overcome the disadvantages mentioned above of the prior art, the utility model is provided in the premise for not changing hydrogenerator shell
Under, more sectional areas for increasing stator core embedded coil reduce the manufacture difficulty of coil, reduce generator terminal and export current reduction
The output voltage of hydrogenerator is improved to the horizontal axis large capacity low pressure hydrogenerator of 660V simultaneously.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of horizontal axis large capacity low pressure hydraulic generator
Machine, including the hydraulic turbine, shell, rotor and stator, stator are made of pedestal and coil, and pedestal is by several anti-zigzag link blocks
Composition, link block is integrally arc-shaped and half is convex groove, and all link blocks, which cooperate, constitutes a ring-type, link block two
End is equipped with generator terminal and draws wire casing；It is correspondingly connected in the convex groove of block half and is equipped with big coil, in addition half link block corresponds to small
Coil, size coil alternately connect.
The small coil is made of two coil units, and big coil is made of three coil units.Using coil unit energy
Combination reduces the manufacture difficulty of coil, and installation is more convenient, and later maintenance is also more easy.
The generator terminal line outlet groove of the two neighboring link block overlaps.Draw in this way convenient for the superposition of generator terminal lead-out wire
Out, it reduces generator terminal and exports electric current, to obtain higher voltage value.
The link block be horizontally arranged state under, the axis inclination angle of link block with 10 ° of vertical direction angle, outside link block
Enclose the insulating layer of one layer of 3-5mm of package.
Water hydro-generator stator is changed to large and small loop construction, to guarantee to increase in limited stator core slot
Add the sectional area of coil, increased the sectional area of generator terminal lead-out wire, reduces generator terminal output electric current.Still further aspect, water wheels hair
Motor stator uses large and small loop construction, reduces the manufacture difficulty of coil.
The utility model has the following beneficial effects: optimizing the structure design of low-voltage high-capacity hydrogenerator, save
Lot of materials, reduces the manufacture difficulty of coil, saves manufacturing cost；Set end voltage is changed to 660V, is solved original
The problem of being difficult to ensure stator temperature rise.By the Structure Improvement Design to low-voltage high-capacity hydrogenerator, its structure is carried out
Optimization, so that the manufacturing cost of equipment substantially reduces while ensure that unit performance requirement, has also won many users'
Praise.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the schematic cross-section of the utility model size coil.
Fig. 3 is the structural schematic diagram of the single link block of the utility model.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Embodiment 1

Son, stator are made of pedestal and coil, and pedestal 3 is made of several anti-zigzag link blocks 3, and link block 3 is whole arc-shaped and one
Half is convex groove 4, and all link blocks 3, which cooperate, constitutes a ring-type, and 3 both ends of link block are equipped with generator terminal and draw wire casing 5；It is right
It answers and is equipped with big coil 6 in the convex groove of 3 half of link block, in addition half link block corresponds to small coil 7, and size coil alternately connects
It picks up and.
The small coil 7 is made of two coil units 8, and big coil 6 is made of three coil units 8.Using coil list
Member 8 can combine, and reduce the manufacture difficulty of coil, installation is more convenient, and later maintenance is also more easy.
The generator terminal line outlet groove 5 of the two neighboring link block 3 overlaps.Section in this way convenient for increasing generator terminal lead-out wire
Area reduces generator terminal and exports electric current, to obtain higher voltage value.
The design of the utility model structure, improvement are characterized in that: water hydro-generator stator is changed to large and small coil knot
Structure increases the sectional area of generator terminal lead-out wire to guarantee the sectional area for increasing coil in limited stator core slot, reduces
