Q: What are the two power distribution equipment?: The two equipment is the equipment for the control, protection, monitoring and measurement of the work of the primary equipment.

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

Q: DC transmission equipment: Simply put, DC screen is to provide stable DC power supply equipment.

Q: Transmission system and distribution system: Simply put, you can distinguish between the end of the cable to the use of electrical equipment (motor, power box) is the distribution system to the substation, transformer is the transmission system

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: What is the role of transmission system and distribution system in power grid: power plant and the load center often separated by long distances, resulting in the problem of power transmission. The power is sent to the user only hydropower area can be fully utilized by high voltage transmission line

Q: Main equipment of high voltage direct current transmission: At present, most of the converter adopts thyristor thyristor rectifier, which is composed of three phase bridge rectifier.

Q: Transmission and transformation equipment: High voltage has a very high risk, and the target electrical appliances do not need such a high voltage, which needs to reduce the voltage through the transformer

Q: Difference between distribution voltage and supply voltage: A distribution within the cell, the high voltage side is 10KV, the low voltage side is 220V or 380V.

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