專家解讀視頻
Covers all types of electrically controlled ac high-voltage circuit breakers above 1000 volts. Applicable to any type of power-operated mechanism - both ac and dc systems. Only includes basic control elements and inclosing of the circuit breaker, but not devices or circuits for protective relaying or special interlocking, as these depend on specific application of a specific circuit breaker.
