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:Rural high voltage transmission line equipment ownership
High voltage transmission line, one end of the power plant (power), the other end of the number of users in the use of electricity, of course, the current
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:Are electric wires and cables belong to distribution equipment?
Wire rod products for the transmission of electric (magnetic) energy, information and electromagnetic energy conversion.
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: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:Difference between distribution voltage and supply voltage
Distribution voltage refers to the power to the end user when the transmission voltage, China's short distance distribution voltage is 10KV.
Q:DC transmission equipment
Power supply operation of power plant and substation in nowadays are used in DC power supply, it provides power for the control of the load and power load and DC emergency lighting load, is the foundation of modern electric power system control and protection
Q:What are the general requirements for working on distribution equipment?
Distribution equipment including high voltage power distribution room, substation, power distribution transformer platform, low voltage power distribution room (box), ring network cabinet, cable branch box] outage maintenance,
Q:What are the two power distribution equipment?
Such as generator, transformer, circuit breaker, isolating switch, bus, power cable and transmission lines, etc..
