(you can understand that they have the "blood" of different personalities inside them.)
Thus, between the two power zones, a special insulation zone (i. E., no electricity) must be set up
Separate them. There's a fatal hard wound in an electrical design:
A fatal assumption is that if a train rises at the same time, it receives two bows。
It's a dangerous moment
By the time the train was travelling at high speed through this sector, the bow had entered the b-power zone and the bow was still in the a-power zone。
At this point, this huge motor unit becomes a two-kilometre-long "mega-guide"
The power grids of two different stages, even different voltages, are connected to each other
The short circuits that erupt in the moment produce a huge arc of horror
In the past few years, the government has been able to reduce the cost of electricity, which has resulted in a massive jump along the electric power depot, and an instant paralysis of high iron
Weights have burned hundreds of millions of dollars of transformer equipment。
So
"one bow running" is the most iron-blooded design of electrical design to cut short-circuit risks
The most unprovoked core security threshold。
Crisis ii: reduce the wear and tear of the wire network (the “saving method” to fine to micrometres)
And then it's the physical wear."
The invisible killer's body fight。
It's not a lubricating bearing
It's a hard-on, high-speed mechanical friction flow。
At 25,000 volts high pressure, carbon skateboards with electric bows slip through the web
Small bumps inevitably produce faint sparks。
This spark, accompanied by high temperatures, causes electrochemical wear and mechanical pull injuries to the network guidance line。
Don't underestimate the extra friction. China's high iron industry is number one in the world
If the rate of wear and tear of the entire network doubles
This means that maintenance and replacement costs of astronomical numbers will be incurred annually。
Every penny saved
It's the bottom of china's power。
Crisis iii: prevention of bow-net resonance (the “air whip” to tame terror)
And that's one of the most physical mechanics aesthetics。
When the train was raging at 350 km/h, the bow in front scratched through the network
It triggers a mechanical swing like a chord to be played。
The wave will follow the guidance line, spreading forward and backward at very high speed。
If the bows in the back were to be raised at this point, they would be attached to the steering line
It's going to hit the swings in front of it:
The front bow disturbance creates a mechanical wave, and the back bow hits the head and triggers a serious resonance
It's like two people working together to shake a rope once the frequency on both sides crashes together
It's a terrible bow resonance. The net of contact is like a crazy whip
It caused the electric bow to jump, and there were frequent "offlines" and "bows."
And even at short notice, the hard metal hanger snaps directly
The air flow and network fluctuations in the back can be fully released in space
It has completely tamed the "crazed dragon"。
Conclusion: this is the chinese standard gold content
Double bow configuration, single bow running。
It looks like a simple eight words behind it
It's a reflection of chinese high iron engineers in mechanics
Electrical and aerodynamics are almost highly critical。
It's not a waste of the more electric bow, lying on the roof
It is china's commitment to the “backside guard” and absolute safety of 1. 4 billion tourists。
When the night comes, watching the light of confidence on the head of the renaissance
In the land of the sacred land, there is no word for pride。
It's not just speed
And it's the strictest in human industrial history
The greatest electrical aesthetics
How many volts is that wire on top of the high iron? Why don't we use communication without a straight stream? It's more interesting than you think。
