Comprehensive technical detail drawing of a power transformer for the Thar 2X330MW CFB Coal-fired Power Plant in Pakistan. The drawing includes:
Key Components
– Bushing Terminals: Detailed specifications for HV bushing terminals, LV bushing terminals, neutral bushing terminals, and regulating bushing terminals with 1:10 scale views
– Valve Interfaces: Multiple valve flange connections including DN100 ball valve flange, DN25 ball valve flange, butterfly valve flanges (DF-50, DF-150, 80), and pressure relief valve interface
– Lifting Diagrams: Bushings lift diagram at 1:25 scale showing proper lifting procedures
– Jacking Base Diagram: Includes specifications for 4 jacks with rated static load of 50t each
The drawing provides critical interface dimensions for maintenance access, oil handling, and electrical connections. All components are precisely dimensioned in millimeters with detailed flanges for oil drainage, nitrogen filling, and chromatographic connections. Connection diagrams for both high voltage and low voltage sides clearly differentiate terminals for proper installation and maintenance.
