Prefabricated box-type substation combined structure installation method

The advantages of pre-installed box-type substations, such as flexible combination, easy transportation, migration, convenient installation, short construction period, low operating cost, small footprint, no pollution, and maintenance-free, have received wide attention.

Due to the compact structure of the box-type substation, each box constitutes an independent system, which makes the combination method flexible and changeable. We can all adopt the box-type, that is, the pre-installed box-type substation equipment is installed in all boxes to form a full-box type. Substation

It is also possible to use pre-installed box-type substation equipment for outdoor installation, equipment and control and protection system box installation, this combination method is particularly suitable for the transformation of the old rural power grid transformation, that is, the original equipment does not move, install a switch box Can meet the unattended requirements.

The box body of the box-type substation mainly adopts the leading domestic technology and production process, and its shell is generally made of galvanized steel plate; its internal frame adopts standard container materials and production technology, which has very good corrosion resistance and can guarantee the equipment 20a is not rusty; the inner sealing plate of the box substation is made of aluminum alloy gusset, and the interlayer is filled with materials with superior fire-proof and heat-preservation performance; automatic adjustment air conditioning and dehumidification devices are installed inside the substation box, and the electrical equipment is not affected by natural The influence of factors such as climate environment and external pollution
