3D Printed Metal Filters Protect Circuit Breakers from Explosion | The Cool Parts Show #57

Circuit breakers used in industrial facilities like oil and gas or water treatment plants protect workers and equipment by interrupting power in the event of an overload. But when a breaker does trip in one of these high-voltage circuits, it releases a large amount of energy in the form of hot plasma gas carrying particles of burnt material; filters are necessary to reduce the pressure and temperature of this explosion and to capture any particulate. Schneider Electric previously produced these parts through assembly, but now is offering circuit breakers featuring 3D printed filters. The filters are produced by contract manufacturer GKN Additive, using HP’s Metal Jet platform for binder jet 3D printing. The binder jetting process enabled the complex and compact geometry needed for the application, while also making the parts affordable enough to produce at scale.

Man, whenever I watch a video from this channel it reminds me we are living in an incredible era for manufacturing. The future is now!

[@fmeg2704]

I get so excited seeing this show I can´t believe I´m such a nerd

[@fadilojifinni9708]

Same here 😂👍🏾

[@dmaass99]

Great episode! Very instructive describing how a real (i.e. production-viable) application goes from initial concept through prototyping through economic analysis through DFM design modifications and finally into production. It's a long journey, put pays off in the end for many applications like this.

[@GoodBaleada]

I love you guys. Never break up!

[@usama.imagineers]

Keep up the good work guys 👍🏻

[@almonster2066]

Maybe a visit to Relativity which is making a 85% 3d printed orbital rocket. An article on their processes would be cool.

Comment for the algorithm

[@GMT_400]

When is AM going to provide smooth wall flow paths off the print for fluid flow components? Also, inspection and ensuring all residual powders are removed from flow paths?

[@cybair9341]

I just hope HP printer cartridges wont clog as often as their ink cartridges.

[@sachitdaniel6688]

I came here to make the same comment 😂

Lol they dont

i like your informative videos. and links to more details if any of the subject is more interested for my field.

The whole problem is actually quite annoying for electricians. The particulates, metals and plastics that blow out of the breaker are from the contacts and structure of the breaker itself. This means that the breaker eventually wears out. It starts to break the circuit prematurely or fails catastrophically. It happens with all high power switches, in fact, and it is due to the inherent inductance of the circuit. It would be nice if AM could solve that problem.

[@srenjensen3817]

Contact wear happens to ALL contact surfaces on circuit breakers regardless of size. But with some industrial brakers, they may only last a few cycles -if that is what one can accept. This filter will help to reduce the contamination of the surounding installation that occurs when a load is switced on or off. It´s not possible to stop the wear, but some alloys have better resistance. One can also use arc an extinguisher, but that is not used for sub 1kV installations. it´s mostly about what one is willing to pay for an installation.

Nice

It looks like the front panel of of Nvidia's DGX rack mount system to be honest.

930v isn't higher than the voltage in my home. I can pump-out 10kv and have resetting fuses up to 40kv and thousands of amps. You forget who you're talking to, your audience isn't housewives.

[@srenjensen3817]

You do not have a "home" that have both 10kV AND +1kA - that is 10 000kW - so you can "pump out" +10 000kWh every hour! I use less that 3000kWh/year in my home.

[@bunnypeople]

Great video! Only thing I would've elaborated on would have been why it would be dangerous for that plasma and particulates to not be filtered. I assume it's to prevent fires in an enclosed space?

[@srenjensen3817]

the particulates get depositet on surounding electrical gear and can cause earth faults or/and an electric arc. You do not want any foreign/ unwanted conductive matter in an electrical enclosure - so steps to reduce the spred of particulates with make the installation safer and make it last longer.
