Differences Between Rural Electrical Substation And Urban Electrical Substation
At present, the application of box transformers in urban network transformation and rural network construction is becoming more and more popular. Combined with the American-type and European-type box-transformer housings that were previously introduced due to different use environments, in order to use the rural and urban grids with significantly different environments, the box-transformer housings that are suitable for the rural grid and the urban grid are also introduced.
1. Box type substaion shell for rural grid
In order to adapt to the problems of limited investment, vast territory, too long power supply lines, and scattered construction projects in the construction of rural power grids, a special distribution box has been developed. Its safety, maintenance, and appearance are better than traditional box transformers. There are obvious advantages. Specially launched a series of products such as: 35KV/10KV rural unattended substation, this kind of box change is suitable for production line production, the cost is greatly reduced, and the popularity in the rural grid is guaranteed.
Install dry-type transformers, 35KV circuit breakers or load switches in the 35KV box. 10KV vacuum circuit breaker and secondary equipment are installed in the 10KV box. The two types of box-type transformers have realized oil-free equipment for all equipment, and have the advantages of low investment, less land occupation, short construction period, and advanced technology. Compared with other conventional miniaturized substations, they have great advantages.
2. Box type substaion shell for urban grid
Under the targeted conditions of miniaturization, energy saving, maintenance-free, and reliable power supply proposed in the process of urban network construction and development, a box-type transformer suitable for urban network transformation has been introduced. The development of modern cities has higher and higher requirements for the environment. For the urban power grid, the spider web-type overhead cables can no longer meet people's demand for power supply, hindering the development of the city.
In order to meet the needs of the city, high voltage is directly required to enter the urban area, the substation equipment goes deep into the load center, the electric energy is transmitted through the underground cable, and the power distribution equipment is always connected to the surrounding environment. Small, easy to install and use, maintenance-free or less maintenance.
There are mainly two types of European-type cabinets and American-type cabinets. European-type cabinets are large in size and low in cost, while American-type cabinets are small in size and compact in structure. American box transformer is a unified design of transformer core, high voltage load switch, protective fuse and other equipment. European-type box-type transformers are indoor and outdoor compact power distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage power distribution devices according to a certain connection plan.
No matter what kind of power distribution equipment box type substation needs, it can reach 70%~80% of the overall urban electrical substation, and the technology of these two products can meet the proposed standardized design, modular assembly requirements, and maintenance-free aspects. research and the improvement of the overall performance of the high pressure device.
Whether it is a box type substaion shell suitable for rural power grid construction or a box type substaion shell in urban power grid transformation, it is all to meet the increasing demand for electricity and the enhancement of power supply stability. Ensure the reliability, safety and stability of the power supply, and meet the electricity demand at the lowest standard.
