Qingdao Electric Group, Box substation with primary voltage range of 6,10,10.5,11,20,22,24,33, 35,38.5kV can be manufactured according to customer requirements.
Hua style box type substation is an improved structure of China's American substation, which replaces oil immersed load switches with external switches (compressed air load switches or vacuum circuit breakers). This structure is called Hua substation. Huabian can be considered as an improved or upgraded version of Meibian.
Hua Style Box substation
Hua style box transformer, commonly referred to as Hua transformer. This type of transformer substation is different from both American and European transformer substations. It is a localized prefabricated substation that takes advantage of the miniaturization of American transformer substations and the automation of European transformer substations to form a unique type of box type substation. It has the characteristics of safety, reliability, convenience, and environmental protection. Especially suitable for use in wind and photovoltaic projects.
Basic structure and characteristics:
Hua style box transformer ,The overall land occupation is relatively small. Unlike the European transformer, the Hua style box transformer eliminates the transformer room, making its overall footprint smaller than the European style box transformer. The incoming and outgoing line structure of the transformer saves a lot of copper materials, resulting in lower overall costs and reduced user investment compared to the European transformer.
Running is safer. The connection method from the high-voltage switch to the transformer is chosen to use busbar connection, which greatly solves the operational safety problems caused by cable connection.
Split structure. The isolation knife, arc extinguishing chamber, and fuse of the high-voltage switch are designed to be placed in separate chambers, which solves the problem of replacing fuses or arc extinguishing chambers in general switches that require power outage of the entire line, truly achieving the performance of single maintenance without stopping other fans.
Structural feature
It is mainly divided into three functional compartments, the high-voltage room, transformer room and low-voltage room. The high-voltage room is fully functional. It consists of a primary power supply system composed of HXGN17-12 ring network cabinets. It can be arranged into a variety of power supply modes such as ring network power supply, terminal power supply, and dual power supply. High-voltage measurement elements can also be installed. Transformers can be S11, S13 and other low-loss oil-immersed transformers or SCB10 dry-type transformers. The transformer room is equipped with an automatic forced air cooling system and a lighting system. The low-voltage room can adopt a panel or cabinet-mounted structure to form the power supply solution required by the user according to the user requirements. It has multiple functions such as power distribution, lighting distribution, reactive power compensation, and user energy measuring, etc.
Product unique Features:
1. The structure of the Huashi box type substation is compact and miniaturized, and the footprint of products with the same capacity is only 58% of that of European box type substations.
The main heating element (oil immersed transformer) in the Hua style box transformer is placed outdoors, while the other electrical appliances are placed in a metal box with a protection level of IP54, eliminating excessive heat dissipation equipment and saving costs.
3. There are three options for high-voltage units: vacuum load switch fuse combination, vacuum circuit breaker, or C-GIS.
4. Installed with gas relay, with light gas alarm and heavy gas protection, to provide gas protection for the system.
5. It is protected from rain, snow, sand and dust, anti-corrosion, fully enclosed, and has the conditions for long-term outdoor use.
6. The entire station is designed with intelligence, and the protection system adopts a substation microcomputer integrated automation device, which can achieve the "four remote" function.
7. We can undertake non-standard design and production of various capacities according to the requirements of the design institute, helping users save investment.
8. Can be used in high-altitude areas up to 3500 meters.
Implementation standards:
1. GB1094.1-2-2013 Power Transformer
2. GB/T6451-2015 Three-phase oil-immersed transformer technical parameters and requirements
3. GB1094.3-2017 Power Transformer
The transportation method is generally land or sea. If you have an urgent need for product use, air freight can also be used for transportation.
