Prefabricated Compact Substation Compliant:
• Ambient temperature: -25ºC~+40ºC.
• Altitude: less than1000m.
• Relative humidity.
-Daily average less than 95% Average value of water vapor pressure less than 2.2kpa.
-Monthly average less than 90% Average value of water vapor pressure less than 1.8kpa.
• Seismic intensity:less than magnitude 8.
• Outside wind speed less than 35m/s.
• Apply to the places have no fire,no explosion danger and no chemical corrosion .
Prefabricated Compact Substation Features:
• The high-voltage chamber has a comprehensive interlocking function to prevent misoperation. According to user needs, tracks can be set up to facilitate entry and exit from the gates on both sides of the transformer.
• Its high-voltage side primary power supply system can be used as a ring network or a terminal, and it can be powered by dual power supplies and can be equipped with high-voltage metering components to meet high-voltage metering needs.
• The low-voltage room can be composed of a panel or cabinet-mounted structure and has multiple functions such as power distribution, lighting distribution, reactive power compensation, energy metering and electricity measurement.
• Each room has an automatic lighting device. All the selected components are reliable in performance and easy to operate. They all have ventilation channels. The exhaust fan has a temperature control device that can automatically start and close according to the set temperature.
• The box is equipped with upper and lower ventilation ducts to minimize the temperature rise caused by outdoor solar radiation in the transformer room and high and low voltage rooms.
• The box has the functions of anti-corrosion, waterproof, dust-proof, heat insulation and ventilation, with long service life and beautiful appearance,under the2.premise that guarantee the power supply reliability. byselecting the box-type substation shell color, thus easy toharmony with the surrounding environment, especiallysuitable for urban construction.
Prefabricated Compact Substation Advantage:
• It has strong completeness, small size and compact structure.
• Safe and reliable operation, easy maintenance and removable.
• It can adopt two methods of natural ventilation and forced ventilation.
• The substston is easy to install on site and work quickly,Equipment mainienance is simple, no special duty is needed, and in particular, it can be loaded in downtown centers, it benefits quality of power suppy,reduce power losses,and enhance reliability of gnd, i means a lot to a new distribution network.
• The pre-installed transformer substation can be customized according to the user's requirement, so the selection scopeis large and the market ability is strong.
• Power supply safety and reliability: can provide perfect,mechanical or electrical linkage, meet the requirement of"five defense", ensure the safety of the person.
• High degree of automation, protection system using microcomputer integrated substation automation devic which can realize "four control", namely, telemetry, remote communication,remote control,remote regulating.Each unit has independent operation function and complete relay protection function. The operation parameters can bset from remote distance to control the humidity and temperature of the enclosure and the smoke alarm meeting the requirements of the unattended. Image remamonitoring can be implemented as needed.
