Q:What is the difference between power supply and distribution: Power supply and distribution is part of the use of general by the Architectural Design Institute of electrical professional

Q:Distribution system equipment classification: Electronic equipment - named meaning, is mainly composed of electronic components

Q:What is the role of transmission system and distribution system in power grid: The power load center is more concentrated in the industrial zone and the big city,

Q:What is the power equipment in the distribution room?: 10kV and below voltage rating equipment, divided into high voltage distribution room and low-voltage distribution room

Q:CHINT group in the transmission and distribution equipment to do it?: not only is the previous low, now from energy production to transportation to use to control a complete solution.

Q:AC distribution equipment including distribution box: Connect the power supply, transformer, converter and other equipment for load distribution box, and monitoring

Q:An introduction to the interpretation of flexible AC transmission systems: synchronous compensator (STATCOM), reactive power distribution is mainly used to improve the system, to adjust voltage and improve the voltage stability of the system;

Q:What are the distribution network equipment: suburbs, towns and rural areas, further allocation and supply industry, agriculture, commerce, industry and residents with special needs for electricity secto

Q:High and low voltage distribution equipment: High voltage distribution equipment: high voltage fuse; high voltage isolation switch; high voltage load switch; high voltage circuit breaker.

Q:Power distribution equipment should be prepared before the blackout?: electrician received power outage notice, pull down the knife switch, accept fuse.
