Air Blast Circuit Breaker Diagram. An air circuit breaker also known as an air blast circuit breaker or acb is an automatically operated electrical switch that uses air to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Breaking by employing a double blast is called a radial blast circuit breaker.
The different ways of flow of the blast of compressed air around the contacts are shown in fig. One important thing to mentio. The air blast flows radially into space between the contacts.
The air blast flows radially into space between the contacts.
In the air blast circuit breaker compressed air is stored in a tank and released through a nozzle to produce a high velocity jet. Construction of air blast circuit breaker interrupter. These are the high capacity circuit breakers and suitable for all ehv applications. On load tap changer in a c.
