How is building electrical engineering divided? Posted by : admin / Posted on : Feb 25, 2021

(1) Traditional division

According to the function of building electrical engineering, people are used to divide it into strong current (electricity) engineering and weak current (information) engineering. The processing object of strong electricity is energy (electricity), which is characterized by high voltage, high current, high power, and low frequency. The main considerations are to reduce loss, improve efficiency and safe use of electricity; the processing object of weak electricity is mainly information. That is, the transmission and control of information is characterized by low voltage, low current, low power, and high frequency. The main consideration is the effect of information transmission, such as the fidelity, speed, breadth and reliability of information transmission.

(2) Modern division

According to GB50300-2001 "Unified Standards for Construction Quality Acceptance of Building Engineering", relatively large construction projects can be divided into: foundation and foundation, main structure, building decoration, building roof, building water supply and drainage and heating, building electrical, intelligent building, ventilation 9 branch projects including air-conditioning and elevators.

Building electrical sub-division projects can be divided into 7 sub-division projects: outdoor electrical, substation and distribution room, power supply trunk, electrical power, electrical lighting installation, backup and uninterruptible power supply installation, lightning protection and grounding installation.

Intelligent building sub-projects can be divided into: communication network system, office automation system, building equipment monitoring system, fire alarm and fire linkage system, safety protection system, integrated wiring system, intelligent integrated system, power supply and grounding, environment, residential ( District) 10 sub-division projects including intelligent systems.

Each sub-division project can be divided into several sub-projects. For example, the residential (community) intelligent system can be divided into fire alarm and fire linkage system, security system (including TV monitoring system, intrusion alarm system, patrol System, access control system, building intercom system, household intercom call for help system, parking management system), property management system (multi-meter on-site measurement and remote transmission system, construction equipment monitoring system, public broadcasting system, community network and information service system, Sub-projects such as property office automation system) and intelligent home information platform.
