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 |
