VS1 indoor vacuum circuit breaker
VS1-12 indoor high voltage AC vacuum circuit breaker with rated voltage of 12KV and three-phase 50HZ AC is used to switch various types of electrical loads. It is suitable for power grid construction and transformation projects such as urban power grids, rural power grids, mines and railways, especially It is suitable for frequent operations within the range of working current and occasions where there are strict requirements for the number of short-circuit breaking operations. The product adopts an integrated design of mechanism and circuit breaker, and can be used as a fixed installation unit and a withdrawable handcart unit.
The VS1 vacuum circuit breaker can perform frequent operations or break short-circuit current multiple times within the working current range; the mechanical life can be as high as 30,000 times, and the full-capacity short-circuit current breaking times can reach 50 times. VS1 vacuum circuit breaker is suitable for reclosing operation and has extremely high operational reliability and service life. VS1 vacuum circuit breaker (ordinary type) adopts a vertical insulating cylinder to defend against the influence of various climates; and in terms of maintenance and maintenance, usually only occasional cleaning or lubrication of the operating mechanism is required. The VS1 vacuum circuit breaker (pole type) adopts a solid insulation structure-an integrated solid-sealed pole, which is maintenance-free. The installation form of VS1 vacuum circuit breaker in the switch cabinet can be either fixed or withdrawable, and it can also be installed on the frame for use.
The circuit breaker complies with GB1984, DL/T403 and IEC60056 and other standards.
VS1-12 can be used for the control and protection of electrical facilities in industrial and mining enterprises, power plants and substations, and is suitable for places with frequent operations.
