  • Structure and function of YBBD buried substation
    Prefabricated pit foundation

    (1) The foundation of the pit can be repressed by more than 6mm steel plate, a fully sealed structure to ensure that surface water and other debris cannot enter the pit: it can also be prefabricated reinforced concrete structure, using advanced waterproof technology to ensure that the foundation does not leak.
    (2) A sump is provided at the bottom of the pit and a submersible pump controlled by an automatic non-water system is installed.
    (3) A high and low-voltage cable installation bracket is installed in the pit to facilitate cable installation and fixing.
    (4) The pit is equipped with waterproof lighting for easy maintenance.
    (5) The foundation top cover is provided with an open manhole.

    Advertising light box type outdoor switchgear

    (1) The protective shell of the switchgear adopts the advertising light box structure, and the two doors of the light box shell can be opened at a full Angle, and the pneumatic spring supports the positioning, which is convenient for the operation and maintenance of the switchgear.
    (2) The light box is provided with a heat insulation haze, which has a good heat insulation effect.
    (3) The two sides of the light box shell are advertising boards, and the LED light-emitting elements with small volume and uniform light source are used.
    (4) The door lock of the advertising light box and the switchgear are set independently, and the maintenance of the light box does not affect the operation of the switchgear.
    (5) The light box shell is provided with an audible and visual alarm device, which can send an alarm signal if damaged by the outside world.
    (6) The switchgear adopts a double-layer door structure, the protection level reaches IP34, and the second layer is the instrument door to ensure that after the light box shell is destroyed, the low-voltage cabinet still reaches the protection level of a complete and independent outdoor low-voltage product.(7) The fan hidden in the light box shell can automatically exhaust and supply air to the pit foundation to reduce temperature and dehumidify.
    Waterproofing of the ground

    The underground combination transformer of the buried box transformer allows the operation of immersed in water, and the waterproof and drainage are added in the pit foundation

    For areas with low underground water level (lower than the bottom of the pit foundation), prefabricated pit structure is adopted, and the ventilation holes at the top of the pit have effective ventilation and rain prevention capabilities. Water can directly penetrate into the ground by laying water-draining sand pebbles at the bottom of the pit foundation; for areas with high underground water level (higher than the bottom of the pit foundation), prefabricated fully enclosed concrete pit structure is adopted. Prevent the inflow of surface water and infiltration of ground water into the pit.
    Heat dissipation from the ground

    (1) The underground transformer uses 13 series of low loss products or amorphous alloy core products, no-load loss and load loss have been greatly reduced, so the heat output is low.
    (2) The high heat resistance of the transformer has a large temperature rise margin, and also improves the overload capacity of the transformer.
    (3) The underground transformer uses naphthenic transformer oil (or high ignition point oil) to ensure that the product has good heat dissipation capacity.
    (4) Between the distribution box and the foundation pit, air inlet and outlet fans are set, and when the temperature rise of the combined transformer reaches the set value, the air supply and exhaust are cooled to ensure the normal operation of the underground transformer.
