Description
Technical field
The present invention relates to a kind of power supply device of bullet train, especially a kind of mobile power supply master circuit is without abrasion
Device and preparation method.
Background technology
With scientific technological advance, mobile power supply is widely used in social activities, and electric locomotive traction is exactly
Typical example.However, the electric propulsion of bullet train, which is able to develop rapidly, is striding forward more high speed, more powerful, more stable side
There is the lifting that many factors hinder overall technology in face, current electric power mobile supply portion.
Electric locomotive power supply the principle is based on electric power is passed through into the single transmission of electricity that is erected above locomotive in modern technologies
Line and the friction plate through being located at the top of locomotive（Carbon brush）Introduce locomotive motor and form loop through rail again, so as to drive locomotive to transport
OK, its supply side and the annexation for sliding access part are that A electric current is transported to C by B in Fig. 1.
In practice, A can be the transportion wire road counted with ten thousand km, and C is the train advanced at a high speed, and B is will be huge
Big electric energy enters the contact of line slip conveying, and only B could drive C normally travels along A high-speed slides.The traveling of electric locomotive, move
Power all originates from slips of the B on A.However, this access way has many defects：
Sliding surface very little is in high-tension electricity, heavy current, high speed situation lower slider again, requires high to A, B material.If can not be normal
Contact, produce spark and abrasion；Also, it is a sliding block for B damage, is then that whole piece passes through for A damage
Circuit.If it is simultaneously inadvisable to lengthen B its lengths, slippery piece resistance is increased if increasing sliding block area and being equal to, to produce machinery pull or
Produce jump.
Supply line A is theoretically bar straight line, and is actually the camber line using each suspension centre as point of contact, is similar in form
Waveform curve, support B faces come from spring with the power that A faces contact.In train high-speed cruising, this resilient support occurs
Serious hysteresis quality, it is that A and B slip becomes successional shake, influences both contact qualities.
The also interference of extraneous factor：Because A and B contact action occurs in the natural environment of train operation, it is transported
Under the conditions of the strength that row process inherently contacts in A with B, therefore, connecing for A and B can be all influenceed when extraneous change somewhat
Touch quality, especially in wind-force, wind direction, air humidity temperature be widely varied, snow and haze in the case of easily make
Into A and B loose contact.
Express locomotive uses more mostly in the prior art to obtain the security and stationarity of more speed and train entirety
The mode of level traction, this method of disposal is very unfavorable actually to A and B contact system.Reason is, in each section
There are several repetition contact points on compartment, have certain spacing distance between each contact point.If using line A certain points as contact
Control point, then one to four is at least provided with train（Based on unillustrated B1, B2, B3, B4 in figure,）It is even more
B points pass sequentially through this control point.When first B1 point passes through contact point, circuit A is geo-stationary, but B1 mistakes
Afterwards, circuit can produce fluctuation, wave, and B2 is then by the control point on this basis, when B2 by after, circuit it is unstable
Property aggravation, the fluctuation of circuit now, to wave be that B1, B2 pass through the superposition after control point.By that analogy, last B
The contact quality of 4 points and control point is well below B1 and the contact quality of control point, after whole train is by this control point
It is very big to the damaged condition of A circuits, moreover, the damaged condition of the higher control point of train speed is bigger.
For development trend, electric motor car speedup is main trend.And implement electric power access side by current technological reserve
Case must just put into the maintaining that huge fund strengthens power main, to ensure the dynamic stability of power main, minimum
Curvature, high-wearing feature etc.；If it is anticipated that because the damaged just necessary paragraph of the abrasion of power line, carbon brush stops, more
Damaged parts are changed, the economic loss thereby resulted in is huge, and the speed-raising that thus problem governs train is also obvious.
