10kV Outdoor Compact Substation Product Description
10kV Outdoor Compact Substation is a efficient and reliable power transformation equipment. It combines high-voltage switchgear, transformers and low-voltage distribution devices in a metal box. It has the advantages of small size, less floor space, and easy installation.
10kV Outdoor Compact Substation can effectively ensure the stability and security of power supply and is widely used in urban power grid transformation, industrial and mining enterprises, residential areas and other places. It is an indispensable and important component of the power system, providing solid power guarantee for our life and production.
High voltage switchgear, transformer, low voltage switchgear trinity, integrity is strong. It has the advantages of small footprint, less investment, short production cycle, convenient movement and so on.
10kV Outdoor Compact Substation plays the role of voltage conversion equipment is transformer, in addition, substation equipment also open and close circuit switchgear, current collection bus, measurement and control transformers, meters, relay protection devices and lightning protection devices, dispatching communication devices, and some substations have reactive power compensation equipment. The main equipment and connection mode of substation vary according to its different functions.
Transformer is the main equipment of substation, which is divided into double-winding transformer, three-winding transformer and self-destructive transformer, that is, high and low voltage each phase share a winding, and a head is drawn from the middle of the high voltage winding as the outlet of the low voltage winding transformer. The voltage is proportional to the number of turns and the current is inversely proportional to the number of turns.
10kV Outdoor Compact Substations are also widely used in wind farms, photovoltaic power stations, hydropower stations, nuclear power plants, hub substations, important converter stations, backbone power grids, important transmission channels and other energy infrastructure scenarios.
