You can see how insulators differ here: http://en.wikipedia.org/wiki/Electrical_insulationChrisToffer said:Can someone please explain to me how do these isolators works, i mean what about the parts? why does it look like this? and what's the purpose of the spring like thing around the isolators?
Suspension insulator - For voltages greater than 33 kV, it is a usual practice to use suspension type insulators shown in Figure. Consist of a number of porcelain discs connected in series by metal links in the form of a string. The conductor is suspended at the bottom end of this string while the other end of the string is secured to the cross-arm of the tower. The number of disc units used depends on the voltage.
Yes. As the wikipedia page says,ChrisToffer said:does the number of ceramic disk in the isolator matter??
The number of disc units used depends on the voltage.
Isolators have a circular spring around them to absorb and dampen vibrations and shocks. This helps protect delicate equipment and components from damage.
The circular spring in isolators works by compressing and expanding in response to external vibrations and shocks. This motion helps dissipate the energy and prevent it from transferring to the equipment.
Yes, there are different types of circular springs used in isolators, such as coil springs, elastomeric springs, and air springs. Each type has different properties and is used for specific applications.
Yes, isolators without circular springs can still be effective in reducing vibrations and shocks. Other mechanisms such as rubber mounts or pneumatic systems can also be used for isolation purposes.
One potential drawback of using circular springs in isolators is the possibility of resonance. This occurs when the natural frequency of the isolator matches the frequency of the external vibrations, resulting in amplified vibrations. Proper design and selection of the isolator can prevent this issue.
