Q:Part of the rated voltage of the power equipment is marked 10.5kv, and this is similar to the label 10KV power equipment what is the difference?Consulted a lot of teachers, but it is said that this is the old and new two methods, I would like to ask what is the basis of this, it is best to have a national standard for reference: Here are a few concepts, you can check1, the network voltage, is the line or the rated voltage of the bus, which is usually said to be rated voltage, including 3, 6, 10, 35, 110, 3302, rated voltage generatorThe rated voltage of the generator is usually 5% higher than the rated voltage

Q:The insulation level of the electrical equipment in the neutral grounding system shall be consideredA. phase voltage;The square root of 2 phase voltage B.;The square root of 3 phase voltage C..Great God in the end this election? I am very tangled!: For example, 220kV transformer (YNYnd11) insulation level high voltage side is LI950AC395-LI400AC200, the front half part (head) of the lightning impulse voltage and power frequency withstand voltage were significantly higher than that of the second part (neutral side). According to the power frequency withstand voltage needs to achieve 1.6 times the rated voltage requirements, the first end of the line voltage is considered in accordance with 220kV, the neutral point according to the phase voltage (127kV) considerations. But there are some places are fully insulated, that is, according to the line voltage calculation.The triangle connection must be considered by the line voltage. Overall, C is definitely right.

Q:For example, EPS emergency power supply and so on, as well as those used in public emergencies.: The latest electric power emergency response and emergency plan for safety protection"Emergency treatment and safe latest power accident contingency plans to protect the implementation of manual" is based on the country's electricity production safety accident emergency system master, provides all levels of power supervision departments and the major power companies, power system, power grid to cope with major public emergencies working principle, organization system and operation mechanism, for guiding the competent departments and local governments at all levels in various industries and departments effectively deal with the power of public emergencies, protect public life and property safety, has an important role to reduce disaster losses.

Q:In power system, the general conditions for the selection of electrical equipment are: Electrical equipment to be as reliable as possible, must be selected according to the normal working conditions and the short circuit conditions for a variety of checks (such as thermal stability check and dynamic stability check)For some equipment also need to check the special items, such as circuit breakers and fuses to check the ability to break the current, the current limiting reactor to check the normal voltage loss and bus residual voltage, etc..

Q:Reactive power compensation methods commonly used in power equipment: For the operation of specific projects, the compensation can be divided into: in situ dispersion compensation and centralized compensation.In situ compensation is to set up a reactive power compensation device on the spot to compensate for a single device. However, the need for compensation equipment, large investment, maintenance management is not easy.

Q:How long has the power of power electronic equipment delivered water: ; equipment (mainly separator population) and pipeline (mainly elbow) wear faster, if the design, construction or improper operation, is easy to cause material deposition, so that the conveying jam, interrupt; transportation should not be high humidity, viscous or easily broken material etc..

Q:Electric power equipment includes what steam turbines are used in what areas of what companies need steam turbines: The main power equipment including power equipment and power supply equipment two categories, power generation equipment is the main power plant boiler, steam turbine, gas turbine, turbine, generator, transformer, power supply equipment is the main transmission line, voltage transformer, contactor etc..The steam turbine is the power equipment, except for the thermal power plant and central heating power station, is also used to drive other equipment, large fan and water pump, ship steel plant, such as large enterprises, pharmaceutical chemical screw compressor etc..Steam turbine and thermal power stations are generally used as the main steam turbine companies, followed by a wide range of applications in pharmaceutical, chemical, metallurgical, petrochemical enterprises.

Q:Definition of power equipment defects: Personal opinion: defects and hidden dangers have certain differences, can not be equated with the...

Q:On the safety hazards of electric equipment safety: 4 where the demolition, the power line protection zones of overweight, lifting, drilling, piling, scaffolding and other construction work, it shall be permitted by the power supply departments, take appropriate safety measures, and can work in the power supply department under the supervision of professional staff.5 prohibit the installation of electric power facilities within the range of 500 meters to carry out blasting operations, fireworks, etc..6 prohibit fishing in the power line protection zone, in case of personal electric shock accident.7 ban on power line protection zones, such as various types of debris piled hay straw, especially prohibit piling flammable and explosive materials.

Q:In the communication and power equipment in the data access to a "remote message quantity" concept, then what is called "remote information", how to define it? Thank you: General electric power on the four remote, remote, telemetry, remote control, remote control, and now there is more than one remote viewing. Remote signal is generally refers to the opening and closing state of each switch, remote measurement is the voltage, current, temperature, etc..
