Power system wiring and transmission and transformation network wiring
Power system wiring
Geographical wiring diagram: indicates the relative geographic location of each power plant and substation and the connection relationship between them
Electrical wiring diagram: indicates the electrical connection between the main components in the power system and the plant
Transmission and distribution network wiring
No backup: single-loop radial, trunk and chain networks, etc., each load can only rely on one line to obtain power, also known as open network.
There are spares: double loop type, single ring type, double ring type and two-end power supply type, etc., each load point can obtain power from different directions through at least two lines, also known as closed network.
Basic wiring form of electrical main wiring
There are busbars: single busbar, single busbar section, double busbar, double busbar section; additional bypass bus or bypass disconnector, double and half circuit breaker wiring, transformer bus group wiring, etc.
No busbar: unit wiring, bridge wiring, angle wiring, etc.
Several basic concepts:
Busbar: It collects and distributes electrical energy and is also called busbar.
Incoming and outgoing: Incoming refers to the power supply, and outgoing refers to the line.
Circuit breaker, isolating switch (busbar, line), grounding knife gate:
