Overview
Compact Substation Transformer (European box transformer) is the high voltage switchgear, distribution transformer and low voltage distribution device three different compartments, through the cable or bus to achieve electrical connection, the used high and low voltage distribution device and transformer are conventional stereotyped products. Intelligent pre-installed substation series can combine high-voltage switchgear (RM6 or SFG, domestic load switch with electric remote automatic control device), transformer, low-voltage distribution equipment, low-voltage intelligent switch, automatic reactive power compensation, according to a certain connection scheme, so that it has local or remote operation to achieve remote control, telemetry, remote metering, remote adjustment and other functions.
Features
Wind farms are generally built in beaches, shallow seas, grasslands, deserts and other sparsely populated
places with harsh natural conditions. Different anti-corrosion processes are adopted according to different
use environments to ensure the service life of pre-installed substations. The overall layout of the box is "product" type, and its advantages are as follows! Compact structure, reasonable, small size; The connection between the main components is convenient, the amount of copper
bar is greatly reduced, the inlet and outlet cable wiring space and maintenance space is large, convenient for
assembly and maintenance. Box structure, all metal structural parts are sand-blasted hot-dip galvanized, spray painting treatment, can ensure that the equipment in the wet, heavy salt spray environment to use its
strong corrosion resistance, all door panels and wall posters, there is no sandwich, the middle filled with
polyurethane and silicate. Composite insulation material, which has excellent thermal insulation
performance, to ensure that the equipment in the cold environment safe, rapid operation.
