What is the difference between Air circuit breaker and Vacuum circuiut breaker?
"Air" and "Vacuum" describe how the breaker extinguishes the arcing current. An Air breaker opens far enough that the dielectric strenght of air is enough to extinguish the arc. A vacuum breaker's contacts are in a vacuum. Oil breakers use oil. SF6 breakers use SF6 gas to extinguish the arc.
What is vaccume circuit breaker?
In VCB, The two contacts are present in a vaccum, When there is a fault these contacts are forced to open resulting arch ,as all we know arch does not flow through Vaccum so it extinguishes thus vcb seperates two circuits.
Can a vacuum is conductor or non conductor?
A vacuum is a non conductor.
When does a vacuum draw the most amperage Free flow or When the tube is plugged?
In the case of a vacuum, the highest load, and thus the highest current, is when the nozzle is free flowing. Lowest current draw is when the nozzle is plugged. If you plug the nozzle with your hand, you will actually hear the motor speed up. This is because it is doing less work (that is, moving air). The vacuum is free spinning (not moving air) when the nozzle is plugged. Check the links section, for a link to a data sheet for an Ametek-Lamb vacuum motor. Notice in the performance curves where the current is maximum (17.4A) when the orifice is 2.0 inches (free flow), and the current is minimum (12.6A) when the orifice is 0.0 inches (nozzle plugged). Also notice how the RPM increases dramatically as the orifice (intake) is plugged. This is opposite of what common sense tells you it should be, but that's the way it is!
Are central vacuum systems electrical?
Central vacuum systems are run by electricity. They were popular in the more 'elite' homes in the seventies and over the years have phased out. It is very rare to find a new home with a central vacuum.
Can a vacuum cleaner work in a vacuum?
a vacuum cleaner uses air to create suction. in a vacuum there is no air. Therefore, the aswer is NO.
Can you hear in a vacuum?
No. Since there is no air in a vacuum and sound travels only with the presence of air, you can't hear in a vacuum.
Is there oxygen in a vacuum?
No there is no air in a vacuum cleaner
Does hot air rise in a vacuum?
No. A vaccum cannot have any air in it, or it isn't a vacuum
What wave can not propagate in vacuum?
Sound waves cannot propagate in vacuum. Air is needed for sound waves to travel and there is no air in vacuum.
What happen when air travel through vacuum?
The vacuum becomes no longer a vacuum.
Where is speed of sound the most in air or vacuum?
Air, given that sound can't travel in a vacuum.
How is air pressure used in a vacuum cleaner?
air presure pushes dirt into the vacuum cleaner.
What is there in space in the place of air if there is no air?
vacuum.
What is it called when air is completely out of air?
vacuum
Can you breathe in a vacuum?
No, as there is no air in a vacuum you would not be able to breathe
How do you create vacuum in vacuum pumps?
vacuum pump revome air from one volume to another valume so that vacuum created on this volume wheres the air removed Type your answer here...
