- Q:What is the working principle of high voltage electrodes and frequency converters?
- High-voltage inverter is the input power supply voltage above 3KV high-power inverter, the main voltage levels are 3000V, 3300V, 6000V, 6600V, 10000V and other voltage levels of high-voltage high-power inverter
High voltage inverter from high - low - high; low - high; high - high points.
- Q:Three sets of batteries (540V) DC power supply U / f inverter.
- It is estimated that the battery should be string - and - series connection method, and then rectifier part of the converter (which may also be caused by the switch) is actually a series of diodes in series, positive and negative after the reverse is actually the battery is Negative shorts, resulting in burning, as to burn only one of the group of a few cells, it should be string - and - string and that group, because the parallel to bear it double voltage.
- Q:Is the motor having a variable frequency motor and a variable voltage motor?
- It should be no change it is the input / output current is v frequency is its input / output frequency is M / Hz
- Q:How to view your own laptop power adapter is how much tile?
- There are signs on the power adapter, you look for sticky paper to write the voltage and current power. If there is no write power, the direct voltage multiplied by the current is the maximum power.
- Q:Speed of 3000 r / min three-phase motor how to change its speed
- The key lies in two points: 1, you ask the variable range is how much? 2, your motor had a few qualifying?
If your motor is 6 outlet, and you only need to speed, plus your motor is also an asynchronous motor, and you do not have the requirements of the load; then congratulations, you can achieve "speed" You just put the motor wiring way to do a △ - Y or Y - △ conversion can be achieved.
If the above conditions you have one or two can not meet, then your best way is to buy a drive to achieve the variable speed. Of course, you can also make some changes to the winding to achieve the so-called single-winding multi-speed operation (this change, but the need for a certain technical content).
- Q:Laptop power adapter leakage
- You feel, or do not feel is to take the amount of pen? If the feeling after it, then for a, if the amount of pen, then hand touched, it should not be bright. That is a induction, is Virtual electricity, it does not matter.
- Q:Is the laptop power adapter AC and DC?
- In the power adapter has a nameplate, marked above the power, input and output voltage and current and other indicators, with particular attention to the input voltage range, if the nameplate indicates that the input voltage is AC 110V, then in China's 220V mains voltage Plug it will burn.
- Q:What are the differences and links between the soft starters and the frequency converters, and their respective principles and uses?
- The frequency changer mainly consists of rectifying (alternating current direct current), filtering, re-rectifying (direct current alternating current), braking unit, driving unit, detecting unit micro-processing unit and so on. Motor asynchronous speed expression bit:
N = 60 f (1-s) / p (1)
Where n --- the speed of asynchronous motor; f --- the frequency of asynchronous motor; s --- motor slip; p --- motor pole pairs.
From the formula (1) we can see that the output speed of the motor is related to the input power frequency, slip rate and the number of pole pairs of the motor. Therefore, the direct speed regulation mode of AC motor mainly has variable speed (adjustment P), rotor Resistance speed control or cascade speed or internal feedback motor (adjust s) and frequency control (adjust f) and so on.
And we now use the most widely used is the frequency control, from the speed n is proportional to the frequency f, as long as the change in frequency f can change the motor speed, when the frequency f in the range of 0 ~ 50Hz, the motor speed adjustment range is very width. The inverter is to change the motor power frequency to achieve speed adjustment, is an ideal high efficiency, high performance speed control means.
- Q:Can the four motors be tuned to 2900 rpm?
- Can be used, there are problems you can consult Zhoukou City bearing mechanical and electrical companies, contact the online search Zhoukou City bearing mechanical and electrical companies can search to!
- Q:ASUS notebook power adapter can be universal? is it?
