High-voltage side
Intelligent integrated substation high voltage generally adopts load switch fuse combination electrical protection. After one phase of the fuse is blown, the three phases are linked to trip. The load switch is available in compressed air, vacuum, sulfur hexafluoride and other types. It can be equipped with an electric operating mechanism to achieve automation upgrades.The fuse is a high-voltage, current-limiting fuse with a striker, offering reliable operation and high breaking capacity. See the table below for its main technical parameters. For transformers above 800 kV, vacuum circuit breakers such as ZN12, ZN28, and VS1 can be used for protection.
Low-pressure side
The main switch on the low voltage side adopts universal or intelligent circuit breaker, selective protection; The outgoing line switch adopts the new type of molded case switch with small size and short arcing, which can reach up to30 circuits;Intelligent automatic tracking reactive power compensation device, with two switching modes: contactor and contactless for users to choose.
