An outdoor high voltage vacuum circuit breaker is a circuit breaker designed to operate in an outdoor environment and handle high voltage electrical systems. It uses a vacuum interrupter as the primary switching mechanism to interrupt the electrical current.
A vacuum interrupter consists of two contacts enclosed in a vacuum chamber. When the circuit breaker is closed, the contacts touch each other, allowing current to flow. When it is time to open the circuit breaker, a mechanism is activated to separate the contacts, creating a vacuum arc that extinguishes the current flow.
Outdoor high voltage vacuum circuit breakers are designed to withstand harsh weather conditions and provide reliable operation in outdoor installations. It is commonly used in power transmission and distribution systems and can handle high voltages up to hundreds of kilovolts.
