16-63 kVA Packaged transformer Substation Technical Schematic

This drawing represents a comprehensive technical schematic for a 16-63 kVA packaged transformer substation (KTPN). The diagram details multiple elevations and sectional views of teh self-contained unit, highlighting key components including the high/low voltage compartments, transformer chamber, switchgear, circuit breakers, fuses, and metering equipment. The unit dimensions are precisely specified: 2170mm width, 1550mm depth, and 2050mm height, with accompanying 3D structural framework views showing the enclosure’s steel frame construction. Component layout indicates proper compartmentalization for safety isolation between high and low voltage sections, with access panels strategically positioned for maintenance. The design incorporates standard protection devices including automatic switches, dry-type disconnectors, and ceramic high-voltage insulators. Particular attention has been paid to equipment clearances and ventilation requirements to manage thermal loads—a critical consideration that often affects substation lifespan in enclosed configurations.
