ZGS11-Z.F 40.5KV Wind Power Power Box Change Station

ZGS11-Z.F 40.5KV/0.69KV series wind variable power station is a 0.6-0.69kV voltage issued by the wind power unit to 35kV or 10kV. It is a special equipment output from the grid. New products dedicated to wind power. Its emergence adapts to the trend of establishing wind farms nationwide, and is a supporting product that integrates reliability, security, practicality, and economy.

Features

The transformer of this product uses high -quality silicon steel sheet materials. After electromagnetic optimization, its vacuum load loss and load loss are lower than similar products.

Safety: The high -voltage part uses a load switch+fuse combination electrical appliance, which can quickly and reliably protect the transformer. The low -voltage part can be a circuit breaker or   a knife melting switch. Maintenance of electricity;

High temperature resistance, strong overload operation capabilities

Life long: Life life is more than 20 years

Demonstrate: There is no need to worry about oil and oil changes during the life period.

High protection level: The box with wind -changing uses a double -layer door sealing structure. The closed parts of all doors are sealed by sealing tape. The ventilation port is equipped with dustproof devices, which can effectively prevent the invasion of wind and snow on the wind and snow. The protection level reaches IP54.

Wind -changing shell structure

Overall layout: type font;

The base structure: The base is welded by the standard groove steel; after welding, the base is placed in the surface treatment pool for preliminary treatment. High -quality imported outdoor paint, the thickness of the paint film is 0.3mm.

Box structure: The transformer mailbox is made of 6.0 thick hot -rolled steel welding. It uses a fully automatic CO2 gas protection welding process. The heat sink is made of 1.0mm high -quality low -carbon cold. Without the worry of infiltration, the front box is made of 2.5mm thick -cold rolled steel plate. The door panel consists of a 30mm thick mezzanine composite steel plate (the mezzanine filling material polyacrynal to drink polytamine, which is 30mm thick). The advantages of thermal, sound insulation, anti -condensation and other advantages; the box door lock material is a special lock of cast aluminum type, with handle and lock box cover, galvanized on the surface; high elastic, aging -resistant sealing strips on the inside of the door frame, and the lower side of the door is set up There are buffer wind hooks.

Box top structure: The material is formed by the cold -rolled steel plate, the thickness of the foam layer is 30mm, the foam layer and the top insulation plate are 100mm, and the exhaust channel; The characteristics of radiation, anticoagulation, etc. can be inherited by 300mm snow -covered thickness or 10mm ice thickness in winter;

Box surface treatment: plastic spray (outdoor) guarantees that ten years do not fade, 30 years are not affected; color:

Box protection level: Transformer: IP68; Considering the poor installation environment of the box -type transformer, the high and low voltage boxes are used with cold -rolled steel lanes -type folding edges, with high -strength aging sealing parts, which can make high and low pressure boxes can make high and low pressure boxes. The protection level reaches IP54.

Box transformation station grounding system

The box -type transformer is equipped with a dedicated ground copper bus, which runs through each room. The metal non -band -tiered components and metal components of each room in the box are effectively connected to the ground bus. There are four special copper ground screws on the outside of the base for users to connect with the basic grounding network;

The life of the box -type substation

The overall life span of a box -type transformer is designed by 30 years (except for easy loss components such as high and low voltage melting);
