Is there any compact electronic component used to make a switch that can withstand large currents from a series of capacitors connected in parallel with a total voltage of over 600V?
How "compact" is compact? What kind of switch -- thrown mechanically or electrically?leVanw said:Is there any compact electronic component used to make a switch that can withstand large currents from a series of capacitors connected in parallel with a total voltage of over 600V?
You might also tell us how large is "large".leVanw said:switch that can withstand large currents
Oh lighten up you guys, geeze. We've all used large capacitor banks for laser fun at uni...Vanadium 50 said:I have to wonder if maybe you shouldn't be doing whatever you are planning.
Yes there is.leVanw said:Is there any compact electronic component used to make a switch that can withstand large currents from a series of capacitors connected in parallel with a total voltage of over 600V?
Some of us got paid* to do it too! This one had a flashlamp pumped YAG with two PFNs at 1KVDC, 1KApk, 45J, 10Hzberkeman said:Oh lighten up you guys, geeze. We've all used large capacitor banks for laser fun at uni...

OK, off topic, but I can't resist: Anytime you see a "laser beam" going through space like this picture, it's 100% fake, or perhaps you have a trash can fire or fog in your room (in which case you should turn it off and go home). That's not what lasers look like IRL.berkeman said:Oh lighten up you guys, geeze. We've all used large capacitor banks for laser fun at uni...

Well, back in the day, the smoke in the laser lab wasn't from a trash can fire...DaveE said:or perhaps you have a trash can fire or fog in your room

A very high current typically refers to currents that exceed the standard handling capacity of most electrical switches, often above 100 amps. These currents are common in industrial applications and power distribution systems where large amounts of power are transmitted or switched.
Switches designed to handle very high currents include industrial-grade switches, contactors, and circuit breakers. These devices are built with robust materials and often have specialized contact designs and arc suppression features to manage and break high current flows safely.
Switches that can handle very high currents are typically designed with heavy-duty contacts and robust construction. They may also employ arc suppression techniques such as arc chutes or use inert gases to quench the arc that forms when interrupting high currents. Additionally, cooling mechanisms might be used to dissipate the heat generated by the high current.
Yes, materials used in high-current switches include copper, silver, or alloys that offer excellent conductivity and durability. Contacts are often plated with materials like silver to improve conductivity and resistance to welding and erosion under high current conditions.
Safety is crucial when dealing with high-current switches. Proper installation, adequate insulation, and regular maintenance are essential to prevent electrical accidents. Additionally, protective gear and adherence to safety standards and regulations are necessary to ensure safe operation and handling of these switches.
