Note: Above Rating Can Be Varied Between The Manufacturer.
It has a high speed of operation on short circuit conditions and overload release.
it. ALso, It Requires An External Power Supply. Example: Siemens 3 WL Model.
During Tripping the Circuit Breaker, The Compressed Air Pushes the Breaker Moving Contorys, Blows the Ionized Gas (Free Electron) from the main contact ’s chamber.
Working Principle of Air Blast Circuit Breaker:
Based on the control position, the Air Blast Circuit Breaker is divided into the threepes Such as,
Axial Blast Air Circuit Breaker: The Air Blast is Directed to Longitudinal Along with Arc.
Cross Blast Air Circuit Breaker -Air Blast is Directed at Right Angles to the Arc.
Radial Blast Air Circuit Breaker -Airblast is Directd Radially.
In Earlier Days, They used up to 22kv. But now a day they are imaged Above 220kv to 735kv Voltage level.
Live Operation of 275KV Air Blast Circuit Breaker:
It has many Advantages Such as
High-site tripping with the compact size.
Less mintenance, since the compressed Air Clean the Contorys.
Long Life Than Air Break Type Circuit Breaker.
Fire free
Circuit Breakers.
Next coming to the tank part, the tank is connected with the econom terminal.
Look at the Above Bulk Oil Type of Circuit Breaker, in that the topal volume of the oil is used for both queenching and insulation.
It is using up to 66kv voltage level.
Also, the tank will be connected with the live terminal, it acts as a terminal block.
The SF6 Circuit Breaker and Sulfur HexaFluoride Circuit Breaker the ARE The MOST POPULAR CIRCUIT BREAKERS IN WHICH SF6 GAS USED ARC Quenching Medium.
Channel so that is what are saying here once the electrons get attacated it to the sf6 molecules there is weezized jsees in between the fixed corner and the moving content.
The sf6 Circuit Breaker is used from 6.6kv to 735kv Voltage level.
10-6 TORR VACUM PRESSURE WILL Be Maintaind Inside the Chamber. Vacuum Circuit Breakers are used up to 66kv Voltage Level for Both Indoor and Outdoor Application.
SOME OTHER LOW VOLTAGES and LOW CIRRENT CIRCUIT BREAKERS Are
Earth Leakage Circuit Breaker: Use to Protect the Circuit Against Earth Fault
RCCB -Residual Current Circuit Breaker: Used to Protect the Circuit
Mccb: Molded Case Circuit Breaker. It is an advanced version of Air Breaker Circuit Breaker and It Comes with the Earth Fault Protection.
MCB: Miniature Circuit Breaker and Which is used for propecting the circuit aginst shutcuit and overload.
But in dc, do not have a naturo points, theReface we need to create an artificial zero point to withstand natural transition recovery.
