220kV ~ 110kV modular prefabricated substations are electrical units such as transformers, multi-circuit high-voltage switch systems, reactive power compensation devices, insulated busbars, substation integrated automation systems, communication, telecontrol, metering, and DC power supplies. The principle of reliability, easy maintenance, and integration are integrated and installed in a heat-insulating, fire-proof, anti-theft, moisture-proof, and small animal-proof, five-sided ventilation, fully enclosed, movable steel structure box. It is suitable for the construction and transformation of 220kV small and medium-sized transformer (distribution) power stations in urban and rural areas, and substations of factories and mines. Because it goes deep into the load center, reduces the power supply radius and improves the power supply quality, it is especially suitable for urban distribution network transformation. Comply with the national grid company standards, the new rural electrification standard system and the electrification implementation outline. Really achieved the leap from building a substation in the traditional way to buying an integrated substation!
Features
■ The 220kV ~ 110kV modular prefabricated substation covers an area of about 8-10 acres if using conventional circuit breakers, and only takes about 1.2 acres if using an integrated intelligent substation. (If a 110kv integrated substation uses conventional circuit breakers, The total station covers an area of about 6-8 acres. If an integrated intelligent substation is used, the entire station occupies only about 1 acre); compared with conventional substations, it can save 60% to 80% of the land area, which is in line with national land conservation. policy.
■ Most of the electrical equipment used is produced by our company itself, which effectively reduces product costs; electrical equipment is installed indoors and will not be affected by external factors, and operation and maintenance costs are greatly reduced; all metal structural housings are used for all components They are all anticorrosive, with minimal maintenance, long service life and low energy consumption;
■ The integrated construction scheme is adopted. The conventional design scheme has been constructed many times. The design and construction are carried out according to the existing scheme, and the local adjustment amount is very small. Each functional module such as the incoming line module, outgoing line module, transformer and The protection module only needs to be called directly, and the production cycle is relatively short. The construction period is shortened to 3 months, and the construction period of a conventional substation takes at least about 1 year.
■ Prefabricated integrated substation has little impact on the environment, because the initial construction volume is very small. All construction work is performed indoors except the structure. Noise and electromagnetic radiation during operation are shielded in the metal layer. Moreover, the shell structure is made of metal components, and its service life is much longer than that of brick-concrete and cement structures, and all components can be recycled and reused.
