10kv-35kv Photovoltaic Prefabricated Cabin Power Grid Substation IP54
Summarize
Provide fully modular assembly solutions for substations,reducing floor space by30% and system design, installation and commissioning cycle by 70%; The all-metal prefabricated chamber is equipped with intelligent environmental control system, which can be applied to complex climatic and geological environment such as high temperature, high humidity, sand and dust.
Support eCloud energy cloud platform access, provide remote health diagnosis, fault analysis, maintenance guidance and other functions to achieve unattended substation and equipment life cyce management; The selection of all equipment in the substation can be customized according to actual needs,relliable operation and quality assurance.
Production process requirements and characteristics
The cabin body generally does not have Windows, using fans and air conditioning to achieve ventilation. Air conditioning, heater, fan and other heating and ventilation facilities should be set up, air conditioning, main control room and duty room should be set up Windows to facilitate lighting and ventilation.
The roof of the cabin body can adopt the air conditioning drainage pipe; The floor of the cabin is anti-ceramic and anti-static movable bottom plate, and the steel support of the movable bottom plate is fixed in the bottom of the cabin. The height of the ESD movable bottom plate should be 200 to 250mm,which is conducive to cable laying and maintenance
The interior of the prefabricated cabin shall be equipped with sound security protection and video surveillance measures, and power distribution box, switch panel, socket,etc.
Application field
Wind power generation, photovoltaic power generation, offshore wind power, distributed photovoltaic power generation and other new energy field booster station
Power grid 10-35kV substation
Large factories and mining enterprises for their own substation
Comparison between prefabricated cabin and traditional substation
item | Conventional outdoor substation | Prefabricated cabin substation |
Floor space | About 3000 square meters | Approx.2000 square meters |
Construction period | About 3 to 4 months | The whole station is pre-assembled as a whole, all equipment is prefabricated by the factory, and can be installed on site. The construction period is short, 1 to 2 months |
Cable usage | The device is distributed, and the amount of primary and secondary cables is large | The equipment is highly integrated, the electrical distance is shortened, and the cable can be saved by about 30% |
Environmental requirement | High environmental requirements, wind sand,condensation and other harsh environment areas are very harmful to equipment | All metal cabin design, IP54 protection level, equipped with perfect HVAC system, can prevent sand, condensation, improve equipment reliability |
Construction and management costs | Many buildings,high construction costs;The equipment is provided by different manufacturers, and the coordination and management cost is high | Prefabricated design, the whole station cancels the building, the construction cost is low; All equipment provided by the company, and responsible for all installation and debugging work, low management costs |
Operation and maintenance cost | Open design, affected by the environment, high operation and maintenance costs | Closed design, basically not affected by external conditions such as the environment, low operation and maintenance costs |
