Product Detail
1. Product Display
YB box-type substation is also called European box-type substation. The product conforms to GB17467-1998 "high and low voltage pre-installed substation" and IEC1330 and other standards. As a new power supply and distribution device, it has many advantages over the traditional civil substation. Due to its small size, small footprint and compact structure, it is easy to move, thus greatly shortening the construction period and footprint. It also reduces infrastructure costs.
This substation normally comprises three compartments inside: High voltage compartment, (equiped with high/medium voltage switchgear , such as ring main unit , gas insulated switchgear ,its rated volatge can reach to 40.5kv maximum)Low voltage compartment ,Tranformer compartment (equipped with three phase oil immersed transformer or cast resin dry type transformer)

5. Product Advantage
Our products not only stand the test of details, but also have many advantages, such as the following:
1.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.
2. High and low pressure chamber layout is reasonable and compact, easy operation and maintenance. High voltage switchgear with anti-error interlock function, safe and reliable operation, simple maintenance.
3. It has various types, such as multipurpose type, villa type, compact type, etc. It can be divided into "needle" shape layout and "wood" shape layout.
4. The transformer room is equipped with a thermostat, which can automatically control the transformer temperature to ensure that the transformer runs at full load.
5.FTU can be installed in the high voltage ring network cabinet to realize the reliable detection of short circuit and single phase ground fault. With "four far" function, easy to upgrade the distribution network automation.
6.Working Environment:
Transformer 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.
Product Application:
In addition to providing convenience for People's Daily electricity needs in the city, 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
