Whenever you travel in a train you might have seen these hanging weights near the poles and a strange connection of wires near to them. What exactly are they? Why couldn’t they just use a simple conductive wire arrangement similar to the normal power transmission system? Let’s learn about the details of auto tensioning devices.

As European Train driver, i couldn't spot a mistake. Good work. Only thing that would have been lowkey important is how the Panthograph switches wires without getting tangled up ripping the overhead line down. These devices look like a sled, and are installed at the said point.
@weeardguy
@weeardguy Рік тому
That depends. Those sleds are only found on section-insulations in The Netherlands. The rest just 'interceps' and 'leave' the current contact wire by raising it from the contact wire that really is in contact with the pantograph. Sometimes, composite-material drive-able insulators are used. Long, cilindrical elements between two sections to create insulation while also being able to drive under them with the pantograph while applying power. For section-insulation, we use those sleds (with a rather large type from RIBE being ever more common). But normal Dutch trains run on 1.8 kVDC only, that makes things quite a bit more easy (and complex at the same time due to the high currents involved)

@weeardguy
@weeardguy Рік тому
@@Hockeyking86 We just don't connect jumper wires like that in The Netherlands at all as almost all of our tracks are double and secured like single track (in professional terms: Double single-track safety). It just means that both tracks can be driven on in both directions should this be necessary. Jumper wires are made with long wires connected to the contactwire, up to the catenary wire (with a stress-loop in between to allow for movement at different temperatures) and then extend over to the newly added wire. Usually we double this wire and you'll see two loops. An even more complex situation can be seen here: www.m-voorloop.nl/modelbouw/blikopbovenleiding/bovenleiding-krul-draagkabel-rijdraad.jpg

This world is rapidly passing away and I hope that you repent and take time to change before all out disaster occurs! Belief in messiah alone is not enough to grant you salvation - Matthew 7:21-23, John 3:3, John 3:36 (ESV is the best translation for John 3:36) if you believed in Messiah you would be following His commands as best as you could. If you are not a follower of Messiah I would highly recommend becoming one. Call on the name of Jesus and pray for Him to intervene in your life - Revelation 3:20. Contemplate how the Roman Empire fulfilled the role of the beast from the sea in Revelation 13. Revelation 17 confirms that it is in fact Rome. From this we can conclude that A) Jesus is the Son of God and can predict the future or make it happen, B) The world leaders/nations/governments etc have been conspiring together for the last 3000+ years going back to Babylon and before, C) History as we know it is fake. You don't really need to speculate once you start a relationship with God. Can't get a response from God? Fasting can help increase your perception and prayer can help initiate events. God will ignore you if your prayer does not align with His purpose (James 4:3) or if you are approaching Him when "unclean" (Isaiah 1:15, Isaiah 59:2, Micah 3:4). Stop eating food sacrificed to idols (McDonald's, Wendy's etc) stop glorifying yourself on social media or making other images of yourself (Second Commandment), stop gossiping about other people, stop watching obscene content etc. Have a blessed day!

Not only does the wire need to maintain a constant height over the rail, it also needs to zig-zag sideways, on a horizontal plane over the rails. If the wire was like a straight line, it would quickly wear thru the pentagraphs single contact point. By zig-zagging sideways, it moves the contact point back and forth, over a bar of carbon at the top of the pentagraph. The video kind of shows this, but doesn’t explain that extra bit of complication. I’m not an engineer, but I play one on TV, so I know what I’m talking about. I also play a brain surgeon. Come see me for discounted rates.

The old New Haven Railroad used a very elegant design that reduced the need for intermediate supports and did not require swing arms. It was a triangular shaped wore arrangement with two catenary wires on the top and one contact wire on the bottom. The wires were spaced by droppers designed to keep the contact wire level. Because there were two catenary wires with spacers between them, the whole wire assembly remained straight in the horizontal plane and could be installed with fewer supports. That arrangement worked well for about 80 years.

@justalurker66
@justalurker66 Рік тому
I agree. The "practical" demonstration is better than having all animation / CGI. It offers proof that the wire will sag under its own weight and cannot be level without the additional support. Theoretically one could create animation that arched the wire up between supports. A practical demonstration shows why the wire arches down. My local electric railroad has constant tension complex catenary with each arm pulling the wire left or right from center as well as supporting the messenger wire above and contact wire below. At the transfer points between wire segments each wire rises upwards from a middle point where the wires are level. Constant contact against constant height constant tension catenary. Places where the power source changes from one substation to another are designed differently so the pan does not short the two circuits (but that is beyond the scope of this video).

Thus when train progress, the wear on the train pento will be evenly distributed in a range, instead of a single cut by a perfect straight line. In this way the life span of train pento will be greatly increased.

Between the two networks there will be a 'neutral' section (no voltage) where the supply from one country finishes and the supply from the next country starts. The locomotive driver will know that they need to coast between the two sections. If the two networks are the same voltage and type (for example 25 kV AC) then the loco just continues on. If there is a difference in voltage or supply type (maybe one is DC and the other AC) then the loco has to be a 'hybrid' type which can deal with the different systems and it will automatically switch to the different voltage or system.

Two questions: 1. How long has this system been in use. I only noticed the weights about 30 years ago. Have they always been there? 2. I always wondered how long the wires and the pantograph last. It seem the friction between a speeding train and a cable would be huge. Are the pantographs made especially soft so that they take all the wear and tear? I mean, you don’t wanna replace the conducting cable too often.

You cannot eliminate all the sagging because of gravity. My physics teacher tried to get rid of the dip on his clothes line and he pulled the wire so tight and the poles came out of the ground. Florida sand don't hold well and even before the poles came out of the ground there still was a dip. As for cable cars the trolley has spring action to keep the trolley on the wires and the counter weights help keep some dip out of the wires. 73

These videos are great. This is how engineering should be explained, as solutions arrise, then problems, then solutions to those problems, on and on. Good stuff

I’ve seen what happens when a weight drops. The pantograph got caught up and melted, doubling back over itself. It’s a bit chaotic.

I didn't know that the cable that powered electric train is this complex, i always thought they just strengthen it by making it like a bridge structure. The more you know

Wires can never be perfectly straight - they will always follow a catenary curve. The point of the complicated double wire arrangement is to minimize the actual sag by reducing the distance between supports.

@@KurtRichterCISSP yeah. You can't put a pole every 5-8 feet, but you can put a support wire that frequently. The video does a good job of going over why each element is added step by step.

𝐀] You mostly did not search for this edutainment video. 𝐁] You still watched it till the end, with fascination for the mechanism and admiration for the production quality of the video. 𝐂] You watched it again to try to fully understand everything, but mostly did not (fully understand everything). But even more loved watching it.
