SF6 Circuit Breaker Explained
Learn about the SF6 Circuit Breaker! How it works, its components, design, advantages, disadvantages and applications.
In this article, we will study about SF6 Circuit Breaker and its functioning in detail. Sulfur hexafluoride (SF6) circuit breaker is a type of high-voltage electrical switchgear device. it is used for protecting electrical power systems from short circuits and overload conditions.
In this article, we will delve into the working principle, applications, technical problems, and solutions of SF6 circuit breakers. The full form of SF6 in SF6 circuit breakers is “Sulfur Hexafluoride.” What are SF6 Circuit Breakers? SF6 circuit breakers are a type of circuit breaker that use sulfur hexafluoride gas as the arc extinguishing medium.
The Interrupter Unit is a critical part of the SF6 circuit breaker and is responsible for interrupting the current flow when a fault occurs. It consists of two types of current-carrying contacts: the fixed contact and the movable contact.
In a double pressure puffer type SF6 circuit breaker, the SF6 gas is compressed by the moving piston during the opening of the contacts, similar to the single pressure puffer type. However, in this type, the pressure inside the circuit breaker is varied during the opening and closing operations.
