Question 4: What kinds of high-voltage systems are included in electrical engineering? High voltage is listed separately, others are lighting electricity and power electricity. Subdivided into-lighting: general lighting, safety lighting and emergency lighting; Power: general electricity, security electricity (submersible sewage pump, household frequency conversion pump, elevator, etc.). ) and fire electricity.
Question 5: What are the contents of strong current and weak current in the installation budget? High voltage covers distribution lines, cables, cabinets, lighting appliances, switches, sockets, lightning protection grounding, system debugging, lighting and socket piping. Power pipeline wiring
Weak current mainly includes the installation of TV, telephone, network, building intercom pipeline and wiring, weak electric box and combination.
Question 6: What does strong electricity mean? Strong electricity and weak electricity are people's customary names. Not as a scientific concept.
Generally speaking, the object of strong electricity is energy (electricity). Strong electricity is characterized by high voltage, high current, high power and low frequency. Mainly refers to the power supply with 220/380v voltage. High pressure doesn't count.
Weak current is aimed at strong current, and its object is mainly information, that is, information transmission and control. It is characterized by low voltage, low current, low power and high frequency. For example, weak current engineering includes communication network engineering, television engineering, fire engineering, security engineering, video engineering, etc. And the integrated wiring project for the above projects.
Question 7: What does electricity include? Electricity includes basic theory, applied technology, facilities and equipment. Electricity is a science that uses electric energy, electrical equipment and electrical technology to create, maintain and improve limited space and environment, covering three aspects: conversion, utilization and research of electric energy.
Electrical equipment includes transformers, reactors, capacitors, combined appliances, circuit breakers, transformers, lightning arresters, coupling capacitors, transmission lines, power cables, grounding devices, generators, etc.
Specific electrical majors include electrical engineering and automation, automation, electronic information engineering, communication engineering, computer science and technology, electronic science and technology, biomedical engineering, etc.
Question 8: What items are usually included in the design part of high-voltage power engineering? Telephone, network, television, security, monitoring, access control, all-in-one card, fire alarm and other building intelligent subsystems.
