" light power " described in the utility model is the power less than resistance of showing the special preparation of unit, and promptly engine power is less than generator power.Described engine is meant motor of the present utility model.
The utility model to be cooperating with special effort-saving mechanism both driving wheel less than the power of resistance, and the energy value of institute's output or greater than the energy value of resistance end reaches the purpose of drive train running generating with this energy value.Use is less than the power drive unit of resistance, and is effective, its objective is for few energy consumption, multiple.
Theoretical foundation of the present utility model and feasibility study: the utility model is in the validity of tentatively proving the unit running, only with reference to having used lever balance theory, power conversion and laborsaving lever principle.
In physics lever balance theory, as resistance F
1Greater than power F
2The time, at fulcrum two collateral resistance F
1, resistance arm L
1And power F
2Initial value inconvenience, only adjust power arm L
2Can obtain the balance between two power, its formula is: F
1L
1=F
2L
2. this theoretical explanation: though resistance F
1Greater than power F
2In case, determine its fulcrum, along with power arm L
2The increase of numerical value, less than the energy value that the other end produced of resistance balance or greater than the energy value of resistance end with it just.This is the theory performance of typical power conversion and laborsaving lever, and it is applied in the practice widely.
The utility model has fully been used this theory, and driving wheel 5 wherein is exactly a super effort-saving mechanism in generating set, and its radius is represented power arm L
2..This effort-saving mechanism constitutes the kinetoplast of a super value with power (both outputting powers of the motor) mechanism less than resistance, and the energy value of its formation can be greater than several times of resistance end energy value or more.Super power capacity greater than resistance end energy value has been arranged, and the utility model generating set is to have the ability effectively to drive to finish power generation process.
According to above-mentioned analysis, the utility model generating set cooperates with it by special effort-saving mechanism driving wheel 5 with less power, forms one super power capacity greater than resistance end energy value, and the formation of this strand energy is exactly according to lever balance-type F
1L
1=F
2L
2. be the basis, establish inequality F
2(L
2.+C)＞F
1L
1Get in the computing formula for unit, annotate: C is a positive number, L in its formula
2.+C be the radius r of driving wheel 5, then C is the uncertain length of appending of driving wheel 5 radius r, so L
2.+C determining the synthetic of power end energy size, and the possibility that drives the resistance end is being arranged.In order to prove feasibility of the present utility model, following data illustration is arranged:
If: resistance F
1(generator power 10000KW), resistance arm L
1(driving wheel main shaft radius 0.1m);
Power F
2(motor power (output) 500KW), power arm L
2(driving wheel radius)
Solve: balance point power arm L
2Length, both radius size of driving wheel
According to balanced type: F
1L
1=F
2L
2, 10000 * 0.1=500L is arranged
2, L then
2=2 (m)
Learn according to calculating: the driving wheel radius is that 2m can satisfy its balance requirement.
Yet the utility model designing requirement: F
2R＞F
1L
1If r=L
2+ c
Then have according to set point: 500 * (L
2+ c)＞1000 promptly: 500 * (2+c)＞1000
If c is made as 1. then have 500 * 3＞1000 promptly: 1500＞1000
So analogize c and be made as 2,3,4 ... 10 or more for a long time, F
2The energy value of r end will be greater than F
1L
1More than end several times of energy value or the several times.
Draw from above-mentioned argument: the utility model is with according to lever balance-type F
1L
1=F
2L
2. the foundation of adjusting the energy configuration as unit is very important, only on the balance basic point of unit energy configuration, could determine the c value that makes unit effectively drive.
The data that above-mentioned illustration is provided, the configuration of installed capacity and power is 20: 1, it is excessive to some extent that such ratio seems, but from the demonstration the result be feasible, moreover the installation proportional arrangement have certain retractility, changeable.
Speed increaser in the utility model is a consumption force mechanisms, and the radius of labor-saving structure driving wheel is big more routinely, and its rotating speed successively decreases, and the rotating speed that speed increaser will be responsible for losing remedies, and becomes motive rotating speed again, and satisfies the required rotating speed of generator.Yet this proportional rotating speed conversion and the laborsaving power that equals to be consumed are nonsensical.Therefore the method that solves this situation has three:
1, select high rotating speed engine (motor) for use, make the rotating speed of the rotating speed of engine greater than generator, the radius of making every effort to the labor-saving structure driving wheel strengthens, and its rotating speed shades or do not subtract;
2, on the basis of motive power end energy value, on same driving wheel main shaft, add the F of same rotating speed
2(L
2+ c) or on same driving wheel, add the F of same rotating speed
2With its kinetic force value that doubles;
3, select for use or make the most accurate most advanced speed increaser, and on speed increaser, add external force auxiliary body, to alleviate the load of power end.
Speed increaser speed change consumption power and carrying resistance that the resistance that forms and driving wheel deadweight form all is the indirect resistance of unit is being calculated resistance F
1With power F
2Proportioning the time, should include its indirect resistance in F
1Calculate in the lump.
The startup of the utility model generating set is carried out under the state of generator zero load, huge is used to power when driving wheel forms, when unit operation is tending towards normal speed, the transmission of electricity of closing a floodgate again.Variable-frequency governor control power F
2Make the unit running steadily.
As two groups of power F are set on the driving wheel
2, can replace work done by turns, also be convenient to maintenance and maintenance.
The difficult point that the utility model is implemented: 1, will use prominent in the world electricity to fail engine; 2, use or cast the driven wheel of diameter maximum in the world; 3, use or make the speed increaser of volume maximum in the world.
