  • Design principle of high voltage vacuum circuit breaker

    At its core, a high voltage vacuum circuit breaker comprises crucial components, including contacts, vacuum interrupters, operating mechanisms, and control circuits. The fundamental working principle revolves around utilizing a vacuum as the insulation medium between the contacts. When the circuit breaker is in a closed state, the contacts establish a conducting path for electrical current. However, during a fault, the vacuum interrupters swiftly extinguish the arc formed between the contacts upon separation, ensuring a safe interruption of the current.
