Sf6 Circuit Breaker Control Circuit Diagram. The circuit breaker in which the contacts open and close in the sf6 medium is called the sf6 circuit breaker. Circuit breakers control circuit functions diagram description.
A circuit breaker in which sf6 under pressure gas is used to extinguish the arc is called sf6 circuit breaker. A typical wiring diagram with dc control for a westinghouse dhp is shown in the figure below. A quick look at a typical medium voltage circuit breaker control scheme with an explanation of important components.
This is accomplished by electrical components on the circuit breaker operating mechanism.
Medium voltage circuit breakers air magnetic sf6 or vacuum type are designed to operate electrically. 2 mechanical operating mechanism that releases the energy to move the main contacts open and close not part of the control circuit. Quite often it is overwhelming to make sense of the entire scheme at a glance. Understanding a breaker scheme is important if you plan on designing a substation.
