Electric Power Networks: Subsystems, Components, and Structure
Electric Power Networks
Production Subsystem
This subsystem includes all electric power generating plants. Electric power generally requires a country.
Transport Subsystem
This subsystem starts at the substations lifting power plants and reaches down transformer stations through transmission lines (MAT Transport and AT).
Distribution Subsystem
This subsystem consists of primary distribution networks.
- BT = 230/400 V
- MT = 20000 V
- AT = 30000/66000 V
- MAT = 132000/420000 V
Mains
All elements and drivers are designed for the union and connection of electric power generating plants to subscribers through transformer stations.
Substation
A processing center through which the output voltage is reduced with feed and AT.
Center Cast
A strong feeding center where one or more AT lines are derived from others with the same tension.
Structure of Electric Networks
Red Linear
An AT distribution line with a maximum of 10 processing centers and distribution lines in BT needs.
Red Ring
A distribution line that closes on itself, with 9 processing centers and distribution lines in BT needs.
Red in Multiple Rings
A ring variant consisting of several ring networks.
Normal Spindle Network
Formed by up to 6 lines in AT distribution, with one end connected to a substation or delivery center and the other at a reflection center.
Red in Normal Spindle Multiple
A variant of the above consisting of 2 or more normal spindles at one end connected to a substation and the other at a reflection center.
Red Spindle-Supported
The most complex networks, comprising no more than 6 lines of AT distribution substations connected to 2 or more distribution centers.
Center of Reflection
Ensures the feeding center of the AT lines coming from a substation or distribution center in this area.
Overhead Power Line
A cable set, mounted at a height above the ground, to carry electric power.
Vano (Span)
The distance between two consecutive supports of a line. The distance between these two is called Light.
Arrow (Sag)
The maximum distance between the straight line joining consecutive braces and the lowest point of the driver.
Supports
Support Alignment
Only supports the conductors and ground wires.
Support Angle
Supports drivers at the vertices of the angles that 2 alignments make.
Support Anchor
Their mission is to provide firm points to the line, so that they limit the propagation of longitudinal stress on it.
Support of End of Line
They must withstand, in the longitudinal direction of the line, all the efforts of the conductors and ground wires.
Special Supports
Their functions include crossings, pitch and urban roads, telecommunication lines. Efforts are under vertical and longitudinal loads.
Posts
Posted-Loop
Set up and assembled in sections with 2 screws each. Each section is formed by 4 studs with equal angular wings, linked together by welded loops.
Heights
Armed
Foundations
Made in reinforced concrete, taking care of its protection in the case of aggressive soils and waters.
Lattice Towers
- With useful efforts in 4500dan horn tip, which originated the series of posts.
- Resistant hard-util 7000 pointed dan dan and 9000.
Are constituted by bodies called: head and intermediate sections and anchor sections.
Features
Height
Put extensions, which spliced at the lower end of the section to concrete.
Armed
Combined with your arms and head, covered all the provisions of MV lines.
Crucetas
Foundations
The reversal safety coefficient of 1.5 is verified.
