1. Shell structure

a. The substation frame is made of channel steel and angle steel with sufficient mechanical strength and rigidity.

B. The material of the shell can be cold-rolled steel plate, stainless steel plate, composite color plate or aluminum alloy plate.

c. Steel plates are used to isolate each bracket, and lighting is provided in the substation.

d. The roof is a double-layer structure, which can effectively prevent heat radiation.

e. Transformer room is divided into open and closed. The radiator of the transformer is located outdoors and is used in an open structure, which can use natural wind to effectively dissipate heat. A transformer used in an enclosed configuration has a separate room in which an automatic exhaust is provided to control the temperature in the transformer room.

f. The door of the substation adopts low temperature sealing strip, which can achieve good sealing effect in low temperature environment.

g. The paint on the surface of the substation is treated with baking varnish at high temperature, which can effectively delay the degradation caused by ultraviolet rays.

h. The shell can be painted in a variety of colors to coordinate with the surrounding environment.

2. High pressure unit

a. The high-voltage chamber provides HXGT16-40.5,XGT5-40.5 and HXGT10-40.5 switchgear, which is compact and easy to combine. Users can make various combinations according to their request.

B. HXGT16-40.5 switchgear, equipped with FT16-40.5R-type load switch-fuse combination switch, used for wind power generation and photovoltaic power generation. The invention has the advantages of small size, compact structure, simple operation, convenient maintenance, safe use and the like.

c. XGT5-40.5 switchgear is equipped with VT16-40.5 circuit breaker, which has the characteristics of high breaking capacity, compact structure, superior performance and high reliability.

d. The switchgear has a complete function to prevent misoperation to ensure the safety of operation and maintenance.

3. Transformer unit

a. Low-loss S11 type oil-immersed transformer or SCB11 type dry-type transformer shall be adopted.

B. The transformer is small in size and easy to maintain.

c. The natural ventilation of the transformer room is good, or the temperature of the transformer room can be reduced by automatically controlling the wind of the fan.

d. The use of soft connection between the terminal on the LV side and the bus bar can effectively protect the LV bushing of the transformer from extrusion and oil leakage.

4.LV unit

a. LV switchgear uses TANW1 series smart CBs and TANM1 series MCCBs, or CBs produced by designated manufacturers at customer's request.

B. curtain scheme can be designed according to the requirements of users.

5. Distribution network automation device

a. The automatic terminal equipment is a TA-D20 type, and its design is optimized after considering the harsh environment in which the wind power substation operates.

B. The product has strong ability to adapt to the ambient temperature, has dual optical fiber ring network communication function, has strong anti-interference, shock-proof, moisture-proof, lightning-proof ability, and low power consumption.

c. The product has measurement control, no battery protection, data processing, monitoring alarm and anomaly detection and communication functions.

6. Special uninterruptible power supply

a. Substation installation TA-UP01/TA-UP02 of wind power dedicated uninterruptible power supply produced by Tianan Group.

B. The product has a strong ability to adapt to the environment, resist shock and interference, and has a wide range of stability.
