What are the parts of a substation? . . It would be best to explain each function in detail. . . Urgent need. . .

The primary equipment in the 虙-type substation uses fully enclosed high-voltage switch cabinets (such as XGN type), dry-type transformers (oil-type transformers can also be used, which are lower cost), dry-type transformers, vacuum circuit breakers, The spring operating mechanism, rotary isolation switch, and low-voltage part can be selected according to user requirements. Air circuit breakers, meters, etc. or low-voltage screens, etc. can be installed. The equipment has no exposed live parts. It is a fully enclosed and fully insulated structure, which can completely achieve zero In the event of an electric shock accident, the entire station can operate oil-free, with high safety; the second use of a microcomputer integrated automation system can achieve unattended operation. Its shell is generally made of galvanized steel plate, the frame is made of standard container materials and processes, and has good anti-corrosion properties. The inner sealing plate is made of aluminum alloy buckle plate, and the plywood is made of fireproof and thermal insulation materials.
