AC HV Disconnect Switch
•summary:
1.GN30-12(D) disconnec t switch is an indoor electric apparatus of rated voltage 12kV, three-phase AC50/60Hz
2.It is used to make break and transfer current for HV ele ctric apparatus under situations with voltage and no-load
3.The switch appl ies rotary moving contact which is mounted on the switchgear easi ly.
4.It adopts wal l through instal lation as well.
In electrical engineering, a disconnector, disconnect switch or isolator switch is used to ensure that an electrical circuit is completely de-energized for service or maintenance. They are only used for breaking the circuit and are often found in electrical distribution and substation, where machinery must have its source of driving power removed for adjustment or repair. Disconnectors can be manual or motor operated and may be paired with an earthing switch to ground the portion that has been isolated from the system for ensuring the safety of equipment and the personnel working on it.High-voltage isolation switches are used in electrical substations to allow isolation of apparatus such as circuit breakers, transformers, and transmission lines, for maintenance. The disconnector is usually not intended for normal control of the circuit, but only for safety isolation. Unlike load switches and circuit breakers, disconnectors lack a mechanism for suppression of electric arcs, which occurs when conductors carrying high currents are electrically interrupted. Thus, they are off-load devices, with very low breaking capacity, intended to be opened only after the current has been interrupted by some other control device.
