In electric power distribution, anauto-recloseris acircuit breaker equipped with a mechanism that can automatically close the breaker after it has been opened due to a fault. Generally, a transient fault will open the breaker for a time until a technician could manually close the circuit breaker or replace the blown fuse, yet autoreclosers will attempt to open and close for several times to clear the transient fault. Because of these advantages, autoreclosers are frequently used as protection units for power distribution circuits in substations. Vacuum interrupters, however, as the most important part determine its performance in a certain degree.
Main technical features are: rated voltage ranging from 3.6KV to38KV; rated current ranging from 630A to 800A; rated short circuit breaking current ranging from 12.5KA to 20KA. Our vacuum interrupters are designed to operate under GB1984-2003 or E2 class of IEC62271-100 standards.
