Description

Kiosk is a closed-type integrated substation designed and manufactured in compliance with the following international standards

– Station shell – IEC 1330
– Medium-voltage switchgear – IEC 298
– Transformers – IEC 76
– Low-voltage switchgear – IEC 947-2, IEC 439
– The equipment in the station is installed according to standards, ensuring safety for operators. Medium voltage device compartment is equipped with maintenance-free SF6 gas insulated switch, suitable for Vietnam’s tropical temperature and climate conditions.

The kiosk is designed to address the restrictions that suspension and construction stations have to deal with as follows

– Saving the station area.
– Convenient for transportation, installation and repair.
– Create beauty for the area around the place where the station is located.
– With this type of station, customers can order the whole set or just order station covers and then install the devices later.
– The station is designed to be compact and suitable for areas with narrow land conditions and high aesthetic requirements.

Station structure includes: Station cover

– Prevent the appliance from switching off the medium voltage switch.
– Transformer compartment.
– Prevent switchgear low voltage.

Specifications: Station Cover

– Fabricated by corrugated iron and powder coated on both sides, insulation, natural ventilation or forced.
– Station covers include:

• • Frame: Fabricated from 3 mm thick sheet on CNC machine to ensure rationality and firmness.
  • Roof: Fabricated 2 layers from 2 mm thick corrugated iron with stiffened ribs, insulation layer to ensure the station works well when the ambient temperature is over 45oC
  • Doors: Fabricated 2 layers from 2 mm thick corrugated iron system with firm hinges to ensure firmness and safety.
  • Soles: Made of I 200 steel to ensure stability and stability when moving.
  • All compartments are designed with insect-proof mesh to cause short-circuit incidents.

Standard figures

– The general configuration for the kiosk station is usually arranged as shown in the figure, which is convenient for connecting equipment and cooling conditions for transformers, however, depending on the terrain of the station where the configuration may change to fit. This configuration is often used for stations with a capacity of less than 1600kVA.
– For stations with a capacity of more than 1600kVA, you can use the side configuration to reduce the height of the station, on the other hand because the weight of the MBA is very heavy at this time, it is designed to put the MBA on the base of the station and with the size of the shell. Large stations can warp the base of the station. With such a configuration, the disadvantage is that the cooling of the transformer will be more difficult.
