Quality management "five nos":, ① unqualified materials do not feed; ② unqualified previous processes do not flow into the next process; ③ parts and components fail to assemble; ④ unqualified assemblies do not inspect; ⑤ unqualified inspection do not leave the factory . There must be a more reasonable and complete assembly wiring plan in daily work. The production, transmission, distribution and use of electric power require a large number of various types of electrical equipment to form the main system of power generation, transmission and distribution.

These devices mainly refer to generators, transformers, disconnectors, circuit breakers, voltage transformers, current transformers, power capacitors, surge arresters, cables, busbars, etc. 

They are usually called primary equipment in the power system, and the circuit that connects these devices together is called primary wiring, also known as main wiring, which is also a primary circuit. In order to ensure the safe, reliable, continuous, stable, economical and flexible operation of power production, transmission, distribution and use, and to monitor its working status at any time, a considerable number of other equipment such as measuring instruments need to be installed outside the main system , Automatic device relay protection remote control and control signal appliances, etc.

These devices are usually connected to the secondary winding DC circuit of the current and voltage transformers or the low-voltage circuit used in the factory bending machinery. The circuit they form is called the secondary circuit, wiring Called secondary wiring. The drawings describing the secondary circuit are called secondary wiring or secondary circuit (including auxiliary circuit) drawings. The drawings of the secondary wiring generally have three forms, namely, the schematic diagram, the principle development diagram and the installation wiring diagram (we usually use the secondary wiring diagram).

Schematic diagram of installation wiring diagram and secondary wiring The schematic diagram of the secondary wiring is used to indicate the working principle of the relay protection measuring instrument and automatic device busbar machine suppliers . Usually the secondary wiring and the parts related to the secondary wiring in the primary wiring are drawn together.  On the schematic, all instruments, relays and other electrical   The drawing is a drawing drawn according to the schematic diagram. The general situation of the expanded view: on the one hand, it shows the position of the current and voltage transformers connected to the protection and measurement device in the primary system diagram; on the other hand, it shows the expanded view of the protection control loop. The expanded view can be divided into two parts: AC and DC. The AC circuit expansion diagram generally refers to the wiring diagram of the AC current circuit and the AC voltage circuit...

Some graphics, characters, symbols, codes, functions and functions in the complete power distribution system   Relevant national standards meaning: In the complete power distribution system, the working and control voltages are distinguished by alternating current (AC) direct current (DC) 100mm copper bend , "J, Z", AC, DC, (+, -), the AC rated voltage is 380V, 220V, 10KV, 6KV, referred to as low pressure and high pressure. Circuit diagrams include primary system diagrams, electrical plane layout diagrams, control protection diagrams (also called schematic diagrams), and secondary wiring installation diagrams. As those who participate in production and install complete sets of products, we should know, understand, and be familiar with most graphics, text, Symbol, code, function and function, meaning. The meaning of symbols commonly used in electrical construction drawings: U: voltage, unit "V" I: current, unit "A" R: resistance...
