630KVA Prefabricated Box-type Substation, which is an electrical device integrated with high-voltage switchgear, distribution transformer and electrical switchboard, widely used in small & medium scaled solar & wind farms, and schools, hospitals and other commercial & industrial buildings.
Firstly, let us focus on some advantages of our Prefabricated Box-type Substation;
1. Safe, reliable and mature technology
The subsation body is outdoor type, which can prevent rain, sun, rust, and moisture. The shell is made of high-quality steel plate structure, and the frame is made of standard container materials and manufacturing technology. Deformation, the temperature and humidity control device is installed in the box to reduce the impact of the environment on the normal operation of the equipment. The transformer room, high-voltage room, and low-voltage room all have automatic lighting devices, and the transformer room has a temperature-controlled automatic exhaust device. It can guarantee normal operation in the harsh environment of -40~+40℃.
The cabinet is divided into high-voltage room, low-voltage room and transformer room. The high-voltage room usually uses XGN15-12 ring network cabinets. The transformer can use dry transformers or oil transformers. The low-voltage room generally uses GGD low-voltage cabinets. All live equipment is sealed inside the cabinet. It can completely achieve zero electric shock accidents, and the whole station can realize oil-free operation with high safety. The secondary use of microcomputer integrated automation system can realize unattended operation. The transformer is reliable in quality, advanced in technology and high in efficiency, and it is a finalized and mature product that fully meets the environmental requirements, operation requirements and site requirements of this project. Under the above-mentioned engineering conditions, there will not be any problems affecting the normal and full-load operation of the transformer. The transformer is a SCB13-630/1010±2×2.5/0.4 Dyn11 UK=6% three-phase dry-type air-cooled transformer, equipped with an automatic temperature controller, which is used to trip the high-voltage circuit breaker when the temperature is too high. The transformer is well ventilated and cooled to ensure the long-term stable operation of the transformer under the outdoor temperature of 40°C and rated load. Main busbar A, B, C three-phase sleeve insulation bushing. .
2. Flexible combination
The prefabricated box-type substation has a compact structure, each box constitutes an independent system, and the combination of the whole box-type substation is flexible and changeable. There is no fixed combination mode for prefabricated substations, and users can freely combine some modes according to actual conditions to meet the needs of safe operation. voltage level ranged from 33kV, 20kV,15kV, 10kV to 400/380/220V,n and its current capacity are on customer request.
3. A much lower cost compared with a conventional electrical substation
The box-type substation reduces investment by 40% to 50% compared with conventional substations of the same scale. The box-type substation has less engineering volume than the civil power house, occupies a small area, does not have large-scale civil works, and has a short construction period, and can complete the entire workload in a relatively short period of time.
4. Beautiful appearance
It is easy to coordinate with the environment. The shell of the box is made of galvanized steel plate. The appearance of the equipment is beautiful. On the premise of ensuring the reliability of the power supply, by choosing the color of the shell of the prefabricated substation, it is easy to interact with the surrounding environment.
The prefabricated substation improves the power quality of the power supply at the end of the distribution line, and is especially suitable for engineering fields such as urban construction, rural power grid technology upgrading and transformation, and field construction power supply and distribution.
