Electrical diagrams commonly used terminology technology
1. Semi-centralized representation: refers to the circuit layout of equipment and devices in order to make them clear and easy to identify, will be a project of certain parts of the
graphic symbols in the sketch of a separate layout, and mechanical connection symbols to indicate the relationship between the method.
2. controlled system: the equipment that performs the actual operation.
3. Table: A form of expression in which data are arranged vertically and horizontally, also known as a table.
4. table diagram: a diagram showing the relationship between two or more variables, also known as a graph.
5. parts: refers to the two or more basic parts of the component part of the composition, you can replace the entire replacement can also be replaced
one or more of the basic parts. Such as overcurrent protection devices, filter grid unit, terminal board.
6. Supplementary marking: Generally used as a supplement to the main marking, as well as the electrical function of each wire or harness based on the marking
system.
7. Program diagram: a sketch detailing the program units and program pieces and their interconnections.
8. Subordinate marking: Based on the marking of the terminal to which the wire is connected or the marking of the device to which the harness is connected, the marking system of the wire or harness
.
9. unit wiring diagram or unit wiring table: a
wiring diagram or wiring table that indicates the connection relationship within a structural unit of a complete set or equipment.
10. single line representation: two or more wires in the sketch with only one line representation.
11. wiring diagram: graphic symbols in working order, detailed representation of the circuit ﹑ equipment or set of basic components and connectivity
connections, without regard to the actual location of a sketch.
12. Equivalent circuit diagrams: a sketch of the theory of components and their connection.
13. Independent marking: A system of marking wires or harnesses unrelated to the marking of the terminals to which they are connected or the marking of the equipment to which they are connected
System of marking wires or harnesses.
14. terminal: the conductor used to connect the device to the external conductor.
15. Terminal code: the code of the electrical conductor used to electrically connect with the external circuit.
16. Terminal board: board, block or strip with multiple terminals insulated from each other and usually insulated from ground.
17. Terminal function diagram: indicates the function of the unit of all external terminals, and function charts, charts or text to indicate its internal function
a sketch.
18. terminal wiring diagram or terminal wiring table: a wiring diagram or wiring table indicating the complete set of devices or equipment terminals and their external wiring (including internal
wiring, if necessary).
19. Multi-line representation: each wire in the sketch are represented by a separate line method.
20. Box symbols: A simple graphical symbol used to indicate the combination of components, equipment, etc. and their functions, neither giving details of the components, equipment, nor
considering the connections.
21. Separate representation: In order to make the circuit layout of equipment and devices clear, easy to identify, speak of a project in some parts of the
graphic symbols in the sketch of a separate arrangement, only with the project code to indicate the relationship between them.
22. Symbol element: a simple graphic with a defined meaning that must be combined with other graphics to form a complete symbol for a device or concept
.
23. High-level designator: the designator of any higher-level (for the item given the designator) item of a system or equipment, such as the designator of a thermoelectric
plant that includes pumps, motors, starters, and control equipment pumping units.
24. function: a definition of an operational process that has a specific role in the flow of information, logic, and performance of the system.
25. Functional flow: describes the logical interrelationships between equipment functions.
26. functional diagram: a sketch that represents a theoretical or ideal circuit without reference to the method of implementation.
27. Functional Table Diagram: A table diagram that represents the actions and states of a control system.
28. interconnection wiring diagram or interconnection table: a wiring diagram or connection
table showing the relationship between the different units of a set or equipment.
