Extended data:

First of all, reference materials, symbols and connection methods required by electrical equipment are drawn according to certain regulations, mainly to learn electrical signs and their functions, connect equipment according to design requirements, standardize graphics, and make it reasonable, concise and beautiful, so that people can see at a glance.

The electrical system diagram is the electrical system control diagram. It is an expression used to express the working principle, function and relationship of power supply lines and equipment. It is an integral part of electrical construction drawing in construction and installation engineering. Such as: lighting and power system diagram in civil buildings, power and automatic control instrument system diagram in industrial buildings.

After the installation and debugging of electrical equipment, the electrical system should be put into trial operation to check the quality of electrical devices and installation works. Before the commissioning, the commissioning operation specification shall be formulated; During the trial run, the relevant records of the trial run and the analysis records of the problems should be made, and temporary problems should be dealt with in time to ensure that the trial run of electrical equipment meets the drawings, specifications and technical requirements.

Only when the test run result of the electrical system meets the requirements can it pass the acceptance and be handed over to the user. During the construction warranty period, do a good job in quality tracking service to ensure the normal and reliable operation of the system.
