I think the reason the spring fuse worked well is because you don't need the wire to completely disconnect or melt for it to work. All you need is the wire to sublimate enough for the tension of the spring to be able to tear the wire apart. You won't get much arching because the wire goes in a split second from a short to a significant gap. I think the spring just retracted in the flash as opposed to completely disappearing. That's also probably why there's no residue where the spring used to be. Only where the wire used to be.

@zuthalsoraniz6764 5 ай бұрын

If you go through frame by frame, you can see the wire just glowing a dull red before the flash as (presumably) the heat just weakened it enough for the spring to pull it apart

Normaly the metal used for those whires creates the gas that's needed to stop the arc, combined with the tiny chamber it's enough to play his fuse role. For the fuses tjat are filled with sand it creates a different gas that has not worked has well as those, but because it was filled with a solid it was enough too. The only problem with the last ones was that it could get wet so they wasent that effiscient and precise has the first ones was. NB: my english can be aproximative, that's normal ^^'

6:22 sulfur hexafluoride is what is used in a lot of high-voltage electrical equipment as an arc suppressant. its also like the opposite of helium (if you breathe it in, it stays there and makes your voice a lot deeper, but don't try this since it stays there and can asphyxiate you if you are not careful). ive seen warnings about it on the doors of some rooms with electrical equipment around where i live.

@michaelmoorrees3585 5 ай бұрын

In the power industry they use sulfur hexafluoride (SF6) gas in special arc quenching circuit breakers. Often there's a special mechanism, to open a gas valve as the breaker opens up, to basically blow the arc out. I remember seeing one in action, in "power lab", back in school, when getting my EE degree (1980s). Power lab was scary, as much of the gear was the size of van, with high power resistors that actually glowed under normal operation. Syncing up the large synchronous machine (could work as both generator or motor) just before connecting it to the 3 phase grid, was always a tad sphincter puckering !

@ZoonCrypticon 5 ай бұрын

@adrianfurgol 5 ай бұрын

Are you sure you're not confusing things? As far as I know, there is arc extinction with compressed air, which blows air onto the contacts, blowing the arc away, therefore cooling it down and extinguishing it. SF6 Breakers by itself are different because of the good isolating properties of the gas, but these curcuit breakers are enclosed inside gas-tight housings which are filled with SF6 Gas. It's really fascinating to see the size difference between air-isolated and SF6-isolated switchgear. SF6 gear is wayyyy smaller.

High voltage circuit breakers at substations often have the contacts in SF6 (sulfur hexafluoride) which quenches arcs. High voltage fuses usually use sand or likely similar gas to quench the arc. There are sophisticated gas monitoring systems to ensure warnings if the gas runs low as if it get critical, the breaker will open while there is still gas available to quench.

Gases for arc suppression: Aircraft piston engine magnetos were pressurized with air to a few tens of PSI for better performance at high altitude. Portable industrial x-ray tubes are pressurized with SF6 to around 50 PSI to suppress arcing from tens of kilovolts of potential. Happy holidays, Mehdi.

@drkastenbrot 5 ай бұрын

regular fuses dont use any special gas and arent actually sealed. sf6 would improve performance (increasing the rating of a small fuse), but it is expensive and adds complexity of sealing the fuse. the lack of a seal also helps release pressure in a overcurrent event.

Good demo, Most HV fuses in ring main units (RMU's) have fine sand in them. The fuse element(s) are wrapped around a ceramic former and an explosive discharge which operates a striker pin at the fuse cap and trips the tripping mechanism, after the fuse element has failed, so all three phases are de-energized when one fuse fails. DDO's drop out fuses, the fuse element is held under tension by a spring which aids the separation of the melted fuse element. Also the tube vents out and blows out the remains of the failed fuse when the very loud explosion occurs under fault conditions.

@Jonodrew1286 5 ай бұрын

Also some glass fuses for purely hobby purposes can be repaired - using super fine wire - they are usually soldered to the end caps - they blow just as fast - the ceramic fuses are more robust and filled with silica like mentioned on this post before - using the wrong fuse is very interesting - and the reason for protective heat-Shrink or a plastic enclosure is probably protection against fragmentation of the case - I had a non - repaired standard fuse I used on a HV project that literally exploded into pieces…

Are you sure that the spring vaporized? It may have retracted fully inside the end-cap. I would expect the spring to have a higher current capacity than the fusible element. Also, many high amperage industrial fuses pack sand around the fusible element for arc quenching. I'm not sure if that would also work for high voltage. Sounds like another experiment. (Though the sand will block the view of the camera so it might not be as visually interesting.)

@@HerrJaeger64 Breaking a DC (Direct Current) is often considered more challenging than breaking an AC (Alternating Current) due to fundamental differences in the nature of these currents. Arc Formation: When a DC circuit is interrupted, it creates a sustained arc between the contacts due to the continuous flow of current. This arc can be very difficult to extinguish because the current remains at a constant level. This sustained arc can damage the switch contacts and other components involved in breaking the circuit. In AC circuits: AC naturally passes through zero volts 100 or 120 times per second (depending on the frequency - 50Hz or 60Hz). This zero crossing makes it easier to interrupt because the current naturally decreases to zero, allowing for the arc to extinguish more readily.

@@HerrJaeger64AC has a pulse of current in one direction, which then reduces to zero and then you get a pulse in the other direction. That change happens 100+ times per second for normal mains.

The gas you're looking for is Sulfur hexaflouride. A hypervalent gas that is extremely resistant to ionisation. It's used in high voltage circuit breakers, contractors and switches. It readily dissolves in nonpolar liquids like those used in highvoltage transformers at substations and the like. It allows for much shorter distances between contacts without arcing. Basically it's a stable fluorine compound and it doesn't want to give up or accept any electrons to anything so it takes extremely high voltages to initiate and sustain an arc through it.

I am currently doing a thesis on discharges and more specifically on Paschen's law. This empirical law makes it possible to predict the breakdown voltage (the minimum voltage to trigger a discharge) of a gas as a function of different parameters. We usually express the breakdown voltage as a function of the product of the pressure and the distance between the electrodes (p.d). Observations show that the breakdown voltage admits a minimum for a certain value p.d, it is therefore "easy" to trigger arcs. Thus, to maintain this optimal value, when the pressure decreases, the gap must increase, which is why it is possible to make large arcs in partial vacuum.

Fuses for 50-500vac, in France at least but I think it's the same all over Europe, contain sand, which helps dissipate the arc energy and then the glass created adds insulation to the fuse. On the other hand, you're right about one thing: manufacturers use argon gas, or others depending on the patents I imagine, to create their "cutting chamber" in high-voltage and high-current circuit-breakers, and probably in "big" fuses too. Great video as usual!

So true about springs in HV fuses. Fuses used in the transmission lines *are* spring loaded, inside a cylinder filled with glass-sand, which melts during a short.

@rickyh2896 5 ай бұрын

I'm sure you've seen the fuses they use on (at least in the US) power lines? They have gun powder in them and an expansion piston so as the fuse blows it ignites the gun powder pushing the contacts far apart to quench the arc! Seems right up your alley to build....

For my transformer (4,2kV capable of delivering 3,6A constant) i had homemade glass fuses, but was getting tired of them blowing often due to my experiments, so i made HV breakers. basically a spring loaded knife switch held in place by a piece of metal that gets pulled out of the way by an electromagnet. the trigger is a simple current transformer with some controls (on the primary to not have to work with HV current transformer stuff :) ) That is nice, since now i can just reset them with levers. I also made some risidual current transformers for the "human protection" on 4,2kV but that is a whole other story... By the way, i love your videos! Especially the ones featuring HV stuff

The reason why the arc was bigger in partial vacuum is because air conductivity has a maximum at about 10mbar, to then drop below conductivity at standard pressure. In detector applications, we usually wait to pump out until 0.1-1mbar before biasing detectors because of this

@robertbackhaus8911 5 ай бұрын

Interestingly, this is something that RocketLab discovered a few months ago. At least, discovered how it applied to their electrically-powered rockets in some obscure circumstances. When the second stage started up, a large arc happened somewhere in the system, shutting it down. Maybe a switch enclosure that normally just happened to contain air developed a leak this time, and bled down to a low enough pressure for an arc to form. Their fix was to add a small nitrogen bottle to the second stage, and keep the electrical systems at a known pressure. Their return to flight earlier this week went off flawlessly.

5:02 The relationship between pressure, gap length and breakdown voltage for electric arc is actually quite interesting and it's formulated in Paschen's law (en.wikipedia.org/wiki/Paschen%27s_law ). When the pressure is too low, there are not enough gas molecules to ionize and make an arc. On the other hand, when pressure is too high, electrons have too many collisions with molecules and they're losing too much energy to maintain an arc. So partial air vacuum was an optimal condition, as we have seen on the video. Thanks @ElectroBOOM for showing that!

High voltage glass fuses used in appliances like microwaves, also known as HV (high voltage) or MOV (Metal Oxide Varistor) fuses, typically contain an inert gas such as nitrogen or argon. These gases are chosen for their chemical stability and ability to prevent arcing inside the fuse during operation.

We use fuses with wire of silver, and filled with sand. When there has been a shortcut, they will often crack open, and be black on the contact points. Also there will be a red tip poling out, marking it as broken. It is used on the power grid, 24KV

I worked in the lift/elevator industry for a while. During development we keep blowing expensive fuses so one of the guys who was from Eastern Europe showed us how to make a water fuse. A bit of wire between two screw terminals suspended in a bucket of water. The water cools the wire until it turns to stream around the wire and the wire melts. A small gauge wire could carry 10s of amps. Very cheap and very dangerous.
