10kV State Grid Standard Prefabricated Substation

10kV State Grid Standard Prefabricated Substation

product description

It is a new type of product that combines the advantages of combined transformers (American box-type transformers) and high-voltage/low-voltage prefabricated substations (European-style box-type transformers), and is also a type of standardized box-type transformers of the State Grid.

Features

1. This product is a new type of product that combines the advantages of combined transformers (American box-type transformers) and high-voltage/low-voltage prefabricated substations (European-style box-type transformers).

2. The advantages of the American box changer are compact structure and small size.

3. The advantage of the European-style box-type transformer is that the high-voltage protection function is comprehensive, and the disadvantage is that the area is too large, which is not suitable for places with compact space.

4. The 10kV compact prefabricated substation not only has the characteristics of compact structure and small size of American-style box-type transformers, but also has the characteristics of comprehensive high-voltage protection functions of European-style box-type transformers.

Conditions of Use

Because the width of the product is only 1350mm, it can be applied to the green belt in the middle of the urban road without affecting the normal passage of vehicles and pedestrians. Because the high voltage uses a ring network cabinet with comprehensive protection functions, it can also be used in any place such as residential quarters, wharfs, stations, highways, viaducts, and temporary power consumption at construction sites.

Executive standard

GB/T17467: High Voltage/Low Voltage Prefabricated Substation

GB/T6451: Technical parameters and requirements of oil-immersed power transformers

10kV High Voltage/Low Voltage Prefabricated Substation Standardized Design Customization Scheme (2018 version)

product advantages

1. The box-type transformer is smaller in size and saves floor space, and the floor space is about 1/3 of that of Eurovariable, saving civil construction costs.

2. The high-voltage protection is comprehensive, divided into terminal type and ring network type of power supply, with a wide range of applications.

3. The overall box substation is divided into 6 functional rooms, which meet the requirements of intelligent prefabricated substations.

4. The transformer is placed in an overall closed case, with less noise and radiation.

5. The overall protection level of the box transformer is relatively high, and it can be used in places with large salt fog and dust.

product description

The product structure is arranged in mesh shape, and the power supply mode is terminal type or non-mesh type. From left to right are the high-voltage room, the transformer room, and the low-voltage room. According to the needs of smart substations in the market, the design room, data acquisition room and DTU room can also be added. The whole box substation has a total of 6 functional rooms, with compact structure and comprehensive functions.

Product capacity range: 

The capacity of 630kVA and below can meet the size requirements of 2650*1350*2100mm (length*width*height), and products above 630kVA can be adjusted according to the actual situation.

Scope of product application: 

Because the width of the product is only 1350mm, it can be applied to the green belt in the middle of urban roads, and will not affect the normal passage of vehicles and pedestrians. Because the high voltage uses a ring network cabinet with comprehensive protection functions, it can also be used in any place such as residential quarters, wharfs, stations, highways, viaducts, and temporary power consumption at construction sites.

Product capacity range

It is recommended to have a capacity of 630kVA and below, and products above 630kVA do not meet the following size requirements

Product Size

630kVA box size (length*width*height): 2650*1350*2100mm
