1, drawing electrical installation wiring diagram, the electrical components are drawn according to their actual position in the installation of the base plate. Components occupied by the actual size of the drawing surface to a uniform ratio will address.
2, draw electrical installation wiring diagram, a component of all the parts drawn together, and with a dotted line box, sometimes more than one electrical components with a dotted line box, that they are installed in the same mounting plate.
3, drawing electrical installation wiring diagram, the installation of the base plate inside and outside of the electrical components of the wiring between the connection through the terminal board, the installation of the base plate has a few connected to the external circuit of the lead, the terminal board should be drawn on a few lines of contact.
4, drawing electrical installation wiring diagram, the same direction of neighboring wires can be drawn as a line.
The main role
Electrical wiring diagram of the power system mainly shows the system in the generator, transformer, bus, circuit breaker, power lines and other major motors, electrical appliances, electrical wiring between the lines; by the electrical wiring diagrams can be obtained on the system of a more detailed understanding.
Electrical wiring diagrams for electrical equipment are used to organize the arrangement of electrical equipment in the port number of each component and the port of the wire and cable number, but also organize the preparation of the number of wiring platoon, as a guide to the installation of reasonable equipment wiring and maintenance electricians to facilitate the future as soon as possible to find faults.
