AC power supply method commonly used in power distribution system

AC power supply method commonly used in power distribution system mainly includes the following: single-phase AC power supply: This is the most common power supply method, which is usually used in homes and small and medium-sized commercial facilities. It uses a phase wire (fire wire) and a zero wire (N wire) to supply power to electrical equipment. This power supply method is simple and easy to use, and the cost is low.

The AC power supply methods commonly used in the power distribution system are: 1 three-phase three-wire system.It is divided into triangular wiring (for high-voltage power distribution, three-phase 220-volt motor and lighting) and star-shaped wiring (for high-voltage power distribution and three-phase 380-volt motor). 2 Three-phase four-wire system. It is used for 380/220-volt low-voltage power and lighting hybrid power distribution.

AC power supply mode The AC power supply methods commonly used in the power distribution system are: 1 three-phase three-wire system. It is divided into triangular wiring (for high-voltage power distribution, three-phase 220-volt motors and lighting) and star-shaped wiring (for high-voltage power distribution and three-phase 380-volt motors). 2 Three-phase four-wire system. It is used for 380/220 volt low-voltage power and lighting hybrid distribution.

TN-S power supply system TN-S power supply system is also what we often call a three-phase five-wire power supply system. It is a power supply method composed of 3 fire wires + 1 neutral wire + 1 ground wire.Although the TN-S power supply system is safe and reliable, it requires the largest number of wires and the highest investment cost.

It is divided into single-loop and multi-loop power supply according to the power supply loop. ( 5) According to the form of measurement, it is divided into metered and non-metered power supply. ( 6) It is divided into temporary electricity consumption and formal power supply according to the electricity consumption period. ( 7) It is divided into direct and indirect power supply according to the management relationship.

The picture communication system is divided into several stages

PECS is divided into 6 training stages, and each stage has a clear goal. The following is a brief introduction to the 6 training stages: When students establish a communication mode and improve the spontaneity of communication , you can learn to identify picture cards.

Preparation stage: At this stage, the sender needs to decide the message to be conveyed and choose the appropriate channel or way to convey the information. This may involve choosing a suitable language, text, pictures, videos or other forms of expression.

It is a set of language communication methods specially designed for autistic children, and training is carried out in stages according to the level of children.

The types of communication between foreign civil servants in the system are ()

1. Cross-regional communication Cross-regional communication is a relatively special way of civil servants' communication. This method is mainly to meet the personnel needs of civil servants between different regions, and also to promote cooperation and communication between different regions.

2. There are three main ways for civil servants to communicate: transfer, transfer and suspension exercise. Transfer refers to the transfer of personnel engaged in official duties in state-owned enterprises, institutions, people's organizations and mass organizations to the organs to hold leadership positions or non-leadership positions above the deputy researcher and equivalent level.

3. Communication can be divided into ex officio communication and application communication. Employments of authority refer to the communication made in accordance with the organs.Exchange decision is a kind of administrative order, which is binding on civil servants. Civil servants should obey the communication decision of the organ.

The role of technical communication of the work area subsystem

1. The work area subsystem is an area that extends from the information socket to the terminal equipment. The workspace subsystem is an area that extends from the information socket to the terminal equipment. The wiring requirements of the workspace are relatively simple, so it is easy to move, add and change equipment.

2. TubeThe rational subsystem connects the horizontal wiring subsystem and vertical trunk cables of each floor, and is responsible for connecting and controlling other subsystems. It is composed of cross-connection, interconnection and I/O equipment, which can locate communication lines and facilitate the management of communication lines.

3. Realize the connection between building complexes. The main subsystem of the building complex, also known as the park subsystem, provides a connection point between the external building and the wiring inside the building. The EIA/TIA569 standard stipulates the physical regulations of the network interface to realize the connection between building complexes.

4. The purpose of the work area subsystem is to realize the connection between the work area terminal equipment and the horizontal subsystem, which consists of the connection cable of the terminal device connected to the information socket. It consists of an information socket, a socket box, a connection jumper and an adapter. The design of the workspace subsystem mainly considers the two aspects of information socket and adapter.

5. Including offices, writing rooms, technical rooms, computer rooms and other areas that require telephones, computer terminals and other equipment and corresponding equipment. The workspace subsystem plays a bridge between the user terminal equipment, including telephones, computer terminals, monitors, data terminals, etc., and the information socket of the horizontal subsystem.

6. External technical exchanges: on the one hand, it refers to the country's proactive expansion of foreign economic exchanges; on the other hand, it refers to the relaxation of policies, liberalization or cancellation of various restrictions, no longer adopting protection policies to block the domestic market and domestic investment places, and developing an open economy.
