High voltage side

High voltage of high/low voltage prefabricated substations is generally protected by load switch fuse combination. After one phase of the fuse is fused, three-phase linkage tripping is performed. The load switch is available in compressed air, vacuum, sulfur hexafluoride and other types, and can be equipped with electric operating mechanism to achieve automatic upgrading. The fuse is a high-voltage current limiting fuse with an impactor, which has reliable action and large breaking capacity. See the following table for main technical parameters. For transformers above 800kVA, zNl2, zN28, Vsl and other vacuum circuit breakers can be selected for protection.

Low voltage side

The main switch at low-voltage side adopts universal or intelligent circuit breaker for selective protection; The outgoing switch adopts a new molded case switch with small volume, short flashover and up to 30 circuits: intelligent automatic tracking reactive power compensation device, with two switching modes of contactor and contactless for users to choose.

Transformer

Low loss, oil immersed, fully sealed s9, s10, s11 series transformers can be selected for high/low voltage prefabricated substations, and resin insulated or NOMEX paper insulated environment-friendly dry-type transformers can also be selected. Trolleys are equipped at the bottom to facilitate the access of transformers.
