Q: 1 what is the power system and the power network? 2 what is the rated voltage of the electrical equipment? Why do the power system to use a variety of voltage levels? 3

The electric power network is referred to as the "power grid", which refers to the connection between the bus from the booster station of the power plant to the bus of the substation.

Q: Power equipment sales process, the customer asked the most questions thank you

In order to make electricity sales, electricity is to master the basic skills, to see more electrical and electronic, electric power system, plant power supply and distribution aspects of the books, only solid basic skills can be handy, you should at least master will sell the product knowledge, understand.

Q: How to solve the short circuit of emergency communication equipment

As you can see (xxxxx). But in the national disaster or war, the government can expropriate these hand car car.Thank you! I hope my reply will satisfy you!

Q: What are the technical measures to ensure the safety of the power line equipment?

5 hanging sign and installing fence (fence).These are the contents of safety regulations (line part)

Q: How to handle the qualification test, what kind of power equipment

(a) legal person qualification and perfect organization; (two) the registered capital and net assets of 60 million yuan; (three) the last 3 years to bear the following first items listed, third project and second sub items listed in any one project, and the project quality: above 1 thousand and 330 volts voltage substation 2 or 220 thousand volt substation 5; more than 2 thousand and 330 volt overhead lines 300 kilometers or 220 thousand volt overhead line of 500 kilometers; more than 3 thousand and 220 volt cable line 80 kilometers or 100 meters above the level crossing tower crossing project 1.

Q: I would like to open a company on the construction of power equipment, what needs to be prepared? (including qualification level, capital requirements, etc.) the more detailed the better

In addition to the requirements of industrial and commercial registration, there are two industry qualification requirements. Both are the higher the level, the higher the level of examination and approval department, the highest level, respectively, need to be approved by the State Ministry of housing and national home appliances. The newly established enterprises with no performance can only start from the lowest level four.

Q: Generator, shunt capacitorShunt reactorShunt capacitorStatic compensator

The power supply in the power system is a three-phase sine alternating current generated by the generator, in which there are two kinds of electric power.

Q: Large engineering construction (such as buildings, factories, institutions) distribution room of the power equipment as required? What's the difference? For example, some requirements never power, and some to eliminate harmonics to improve power quality, the more detailed the better the program

Construction of electricity, then it is necessary to look at the site to enter the electricity equipment, under normal circumstances, with 380, 220V power is enough

Q: Electric power equipment includes what steam turbines are used in what areas of what companies need steam turbines

Power equipment including: boiler, steam turbine, pump, deaerator, condenser, generator and so on, from the impact of steam boiler turbine blade hot out of the turns, then drives the generator to rotate to generate electricity, in general, now in thermal power plant and a large Shipping Co to use steam turbine

Q: What is the redundancy of electrical equipment

Disk duplex: a I/O controller is added to the mirrored disk to form a dual disk to improve bus contention.RAID: cheap redundant array of disks (Redundant array of inexpensive disks). As the name suggests, it consists of a number of disks, through a controller to coordinate the movement of a single data flow into the disk. The RAID3 system consists of 5 disks, in which 4 disks store data, and the 1 stores the check information. If a disk fails, you can replace the disk on the line, and through the other 3 disks and check the disk to re create the data on the new site. RAID5 will check the information distributed on 5 disks, so you can replace any disk, the rest with the same RAID3.
