Structural breakthrough
● Fully enclosed armor
A modular fire compartment is composed of three compartments: high voltage room, transformer room, and low voltage room. The enclosure is made of 2mm thick aluminum zinc coated steel plate (certified by IP54 protection and tested according to IEC 62271-200 standard), and filled with flame-retardant rock wool layer inside. Its sealing structure can withstand the impact of sand and gravel carried by 12 level strong winds, reduce the salt spray corrosion rate by 80% in coastal areas, and maintain the normal start and stop of oil immersed transformers in extremely cold environments of -40 ℃. At high temperatures of 45 ℃, the temperature rise is maintained at ≤ 65K through a forced air cooling system.
● Pre installed architecture
Adopting the "factory prefabrication+on-site assembly" mode, 90% electrical debugging including circuit breaker setting, protection relay calibration, etc. is completed before leaving the factory, equipped with fast plug GIS interface and standardized cable trench. On site construction only requires 15 days for foundation pouring (traditional substations require 45 days), and the positioning error can be controlled within ± 5mm through lifting. Typical project cases show that the fastest time from installation to power transmission is only 72 hours.
Technical advantages
● Space Revolution: The foundation covers an area of 8 × 4m (conventional stations require 15 × 10m), and when using a double-layer stacking design, the unit area capacity can reach 4MVA, which is particularly suitable for land scarce areas such as Singapore. The top can be planted with greenery or installed with photovoltaic panels to achieve land composite utilization.
● Intelligent operation and maintenance: Equipped with a multispectral thermal imaging instrument to monitor joint overheating, combined with a high-frequency sampling arc detector (response time<2ms), the data is uploaded to the SCADA system through the IEC 61850 protocol. The practice of a project in Hangzhou has shown that this technology reduces the fault location time from 4 hours to 8 minutes.
● Cost control: Save 120000 yuan/unit on anti-corrosion coating costs within a 20-year period. The transformer room adopts a honeycomb sandwich structure to reduce noise to 45dB (A), meeting the requirements of sensitive areas such as hospitals.
Scenario based application graph
● Urban renewal: In the renovation of Nanjing Road in Shanghai, a combination of 10kV ring main units and SCB10 dry-type transformers is embedded in the basement of commercial complexes, achieving a doubling of power supply capacity without affecting the historical architectural style;
● New energy support: The 200MW photovoltaic power station in Qinghai adopts a containerized booster station, which integrates SVG dynamic reactive power compensation device (response time ≤ 10ms) to solve the voltage fluctuation problem caused by the day night temperature difference in the Gobi Desert;
● Emergency power supply: During the rainstorm disaster in Zhengzhou, six mobile box transformers were transported by heavy trucks to quickly build a 10kV temporary ring network in the dam break area to ensure the continuous power supply of ICUs in three hospitals.
