1, phenomenon (l), lamp installation deviation, not on the center point. (2), the levelness of the rows of lamps and lanterns, straightness error is bigger. (3), chain hoist, chain is not parallel to the fluorescent lamp, under the diesel engine guide wire is not made up again. (4), ceiling fan hook with rebar processing, molding is poor; Bell doesn't absorb top, junction box appears. (5), large balcony lamp chassis plate, rust. (6) Jane lamp hole greatly, smallpox condole top, not neat. 2, root cause analysis (l), embedded lamp box when the position is wrong, wrong, install lamps and lanterns without to www.dongfeng-motor.com take remedial measures. (2), construction people curse is not strong sense of electric water pump responsibility, construction and acceptance of the existing norms, quality inspection evaluation standard are not familiar with. (3), buyer buy lamps and lanterns covet xuan, ignoring quality; 3 phase induction motor (4) was not set well, canister lamp hole size, do not have a unified nation, round hole diameter, etc. 3, preventive measures (l), before the installation of lamps and lanterns, should seriously find center, rectify the deviation. (2), according to French, rows of lamps and lanterns installation deviation should not be greater than 5 mm, therefore, need to stay in the construction of localization, the lamps and lanterns in vertical, horizontal, oblique and Lord with low levels are in a straight ac synchronous generator line.

(3), fluorescent lamp chain hoist should be straight, not appear eight word, under the wire guide should with chain hoist plait fork. (4), embedded ceiling hooks, application of not single phase induction motor less than 8 Ф galvanized round steel reinforced fixed together with the plate and are not allowed to use rebar, processing and shaping hook should be consistent, and brush antirust paint. Bell can suck the top ceiling fans and will hook and the junction box cover. Rows of ceiling fan should be in a straight line, deviation of 5 mm or less. (5), the balcony iron plate thickness of 0.5 mm or more lamps ac synchronous generator and lanterns at the bottom of the box, and the paint surface is smooth, can play the role of rust; The glass can't be too thin, so as to avoid rupture during installation. (6), smallpox condole top tube light opening first shall be good coordinates, in addition to the required straight, neat and equally, the size of the hole should conform to the specifications of the diesel engine canister light, not too big, to acmotor2.blogspot.com ensure that the outer ring when the tube lamp installed firmly against condole top, not crack. (7), construction personnel, procurement staff to carefully implement the relevant state and local regulations.

1, loose phenomenon (1), probe installation, there is crack between, board, ceiling and wall. (2) get too generator close, probe and lamps and lanterns, the sensitivity of the heat effect of lamps and lanterns probe. 2, (1) analysis of the ac synchronous generator causes, construction personnel in the probe base without serious leveling, fixed installation. auto spare parts (2), installing plane is narrow small, embedded tube box didn't pay attention to the probe and the distance flattening of lamps and lanterns. 3, preventive measures ac synchronous generator (1), and sense of responsibility, strengthen construction personnel base installation must leveling with extremely, metope, tighten when install the probe. (2), in general, the smallpox of toilet area is lesser, often make lamps and lanterns and intelligent probe was too close, then the center of the lamps and lanterns should be properly adjusted and probe the distance from the window, ensure that both the distance around 50 cm. Public www.facebook.com/guohong.trading walkway on the top of the smallpox of fire detector, when embed box should be that diesel engine of the lamps magnetic generator and lanterns ac motor to keep boy 50 cm of distance (guarantee) in the center position of lamps and lanterns.

What is the voltage, current, power? Radio enthusiasts are very clear. When it comes to "level" to clear the human are not actually many. Although people often encountered, also many times in books about circuit of high level and low level, level, level attenuation gain, even necessary electrical multimeter has designed Three phase motor the method of level measurement and carved lines, and the "dB", "dB mu", the words "dBm" are often visible. Nonetheless, because of "level" itself abstract concept, and the more appropriate metaphor, so people always understand, memory is not deep. What is "level"? "Level" refers to two or several circuit quantity relative ratio under the same impedance. In this case, the power of natural small diesel generator "electrical power", "voltage", "current" and multiples into a logarithmic, expressed in the "dB", as "dB".

Respectively as: 10 lg (P2 / P1), lg (U2 / U1) 20, 20 lg (I2 / I1) in the type P, U, I is the power, voltage, current, respectively. Using the "dB" has two advantages: first, speaking, reading and writing, convenient calculation. Such as the total magnification of multistage amplifier for all levels of magnification multiplication, in decibels can switch to add. The second can truly reflect the feeling of sound. Practice has proved that the decibels of sound small generator to increase or decrease one times, the human ear hearing loudness also increase or decrease one times. The human ear hearing is proportional to the power of sound decibels. Calls such as mosquito differ with artillery sound 1 million times, but it feels just 60 times, 1 million times and just 60 db.

The inverter no-load current is greater than the load current

A 75 kw micro can WIN - G9 inverter commissioning the strange phenomenon.The feeling.Consult factory.Because in a hurry to solve the permanent magnet motor problem,find out,this time without long distance telephone bill is expensive or not.Frequency converter manufacturers and technical personnel reply:this type inverter as the earliest production of frequency converter,a little older no-load current,current fluctuation problem,but belong to normal phenomenon does not affect the use.After the load current will stabilize.Test it with better access to a power motor,you the problem of motor run capacitor the motor,or load problem.Such as motor bearing problem.Problems such as motor and load all ruled out,as long as the inverter output three-phase voltage balance,output current shall not exceed the rated current transducers and can light or load commissioning.


Bad not to drop.As for the proportion of input,output,current problems,due to electricalmotor1.blogspot.com the load is different,it is very difficult to have a fixed ratio.Out of proportion.Don't and proportion problem entanglement.Wanting is also.As long as it is the output three-phase voltage balance,as long as it is in the case of no more than rated current,can bring a load test.Inverter bad not to drop it.Perhaps after loading,the output current will not have motor magnet large fluctuations.Might be normal.Had to take load test,a miracle (surprisingly) :10 Hertz runtime,at 40 a output current,output current is only 7 8 amp.30 hz runtime,60 a output current,input current 25 a.40 hz is run,when output current 100 a,70 amps input current.Running current small,small ripple,is basically stable.Three phase voltage and three phase current balance and relatively stable.Problem has been solved somehow.

Why can't transformer dc transformer?

Transformer can mini electric motor change voltage condition is that the original edge to ac electric potential to produce alternating magnetic flux,alternating magnetic flux will be produced at the edge of the deputy induction electric potential,the size of the induction electric potential is proportional to the change rate of flux.When transformer dc trendy,due to the current size and direction are the same,no alternating magnetic flux in the core,namely the constant flux and flux rate is zero,so the induction electric potential is zero.At acmotor2.blogspot.com that moment,all the dc voltage applied in winding with electric motors pricesmall resistance,the current is very large,approximate short circuit phenomenon.

And alternating current (ac) is the change alternately,when access to primary winding alternating current (ac),also with the change of the formation of magnetic flux in the core,is greater than the primary and secondary turns,can increase the voltage;On the other hand,the secondary coil number less than primary can buck.Because of the size of the direct current (dc) and the direction does not

change with time,so constant direct current into ac electric motor the primary winding,the core flux was constant,cannot in the secondary winding induction potential,so no pressure.
