Primary circuit diagram of a factory's power system

This section mainly introduces the power system transmission process, common electrical primary and secondary wiring diagrams of factory power supply and distribution systems , and becomes familiar with the corresponding graphic symbols
and methods of electrical wiring diagrams .
    The low-voltage side bus adopts segmented wiring, and isolation switches and circuit breakers are used to connect and disconnect the power supply and load.
    In order to ensure that the transformer is not damaged by atmospheric overvoltage, an FS-10 arrester is installed on the high-voltage side of the transformer. Each current
transformer shown in the figure is used by the measuring instrument in the line.
    The figure shows a single busbar segmented radial power supply system, using an isolation switch to connect I. ⅡTwo sections of busbar. There are a total of 14 branches of the power distribution panel supplying power to electrical equipment
. The system adopts dual power supply and busbar segmented wiring. The power incoming line and wiring adopt the power distribution panel.
The overall structure is compact, easy to use, and convenient. Installation and maintenance, power supply reliability provider.
