Description
Dear All,DC Distribution Panel (DCDB), are the one of the important panel in substation / power plant / factory etc. DCDB explained in this training has two incomers (two sources). One supply is feed through Battery Bank – No:01 and other is feed through Battery Bank- No:02. Interlocking is provided between incomers and coupler, we have explained single line diagram, interlock logic, interlocking schematic / wiring functionality is explained, what is normal position of any equipment, normally open and closed concept is also explained. Finally you can find schematics drawing for self-study.Following topics are covered.• Content List• General Characteristics• Component List• Single Line Diagram• Legends• Under Voltage / Over Voltage Relay F27• Concept of in comer and outgoing feeders• Use to bus tie breaker• Need of DC supply / batteries for at substation for control and protection• What is disadvantage of using AC supply for control and protection• Protection philosophy, tripping and closing coil function• Interlocking of Incomer 1 & 2 & Bus Tie explained• UVT Under Voltage Trip Coil in Air circuit breaker• Timer circuit• Trip / Close Coil Save contact• Interlock Logic, Auto Manual Off operations• Symbols & Legends• DC Supply Distribution SLD Drawings• Aux Contacts use, NO & NC• DC Supply Distribution detail Drawings• Metering & Indication Circuit at Control Panel• DC Annunciator Circuit• Socket & Lighting Circuit• Typical Lamp Test Scheme• Terminal Strip Drawings• Front and Side View Best Regards
