Q: What are the two power distribution equipment?: Such as generator, transformer, circuit breaker, isolating switch, bus, power cable and transmission lines, etc..

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

Q: What is the power equipment in the distribution room?: The indoor power distribution room with low voltage load is called the power distribution room,

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: Mechanical equipment is made up of mechanism, power mechanism, transmission mechanism, actuator and control system

Q: High and low voltage distribution equipment: Distribution equipment refers to a variety of power plants, substations and factories and enterprises in the low-voltage power distribution system for power, distribution and lighting of the complete sets of equipment.

Q: Transmission lines are not electrical equipment?: Transmission lines are not electrical equipment? The answer is: the device is a function of the assembly

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: Rural high voltage transmission line equipment ownership: the transformer can be what, look at the role of electrical appliances can be
