- Q:Laptop power adapter current is not the same alternative?
- so the output voltage, the same output polarity, the output current of the adapter can be used in smaller power notebook, and small power adapter can not be used to give Powerful notebooks,
- Q:My inverter is the era TVF8000 series, the motor is 15KW6 pole motor, has been used for 3 years.
- If the frequency converter is selected according to the motor rated current, then the motor current exceeds the rated current, the inverter will become overcurrent protection
In this case, that is, when the inverter began to select the amount of time to stay the lack of the same power, inverter general type than the fan pump type current capacity of a high grade
If the inverter selection is no problem, then please see whether the inverter is working temperature is too high, too high will cause the electronic components to resist the decline in current.
First, check the inverter to work the ambient temperature, the second Please check the inverter fan is damaged, clean down the inverter fan channel and fan to see if there is no plug
- 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:Can the laptop power adapter be generic?
- Not common.
Different computer adapter interface is not the same, and the voltage, current is not the same.
If just the same, you can use, the voltage can also be used.
- Q:Three motors, if coupled with the governor speed, is it necessary to add the inverter?
- Third, the cascade speed: Cascade speed refers to the winding motor rotor loop in the adjustable resistance to change the motor slip, to speed the purpose of the past, the most widely used.
- Q:What is the number of parameters of the motor frequency of the Siemens inverter?
- Siemens inverter motor pole number parameter code is r0313 motor pole pairs. Note that the number of pole pairs.
- Q:Pump frequency converter instantaneous restart and restart the problem
- Inverter speed:
Based on the advantages of speed control, energy saving and reliable operation, the frequency converter has gradually replaced the traditional variable speed, electromagnetic speed and voltage regulation. In the introduction of PWM flux vector control of the inverter a few years later, the end of 1998 and the emergence of DTC control technology inverter. ABB's ACS600 series is the first generation of DTC technology using the inverter, it can open the ring speed and torque for accurate control, and dynamic and static indicators have been better than PWM closed-loop control indicators. Direct torque control to measure motor current and DC voltage as input to the adaptive motor model. The model produces a set of precise torque and flux actual values every 25μs. The torque comparator and flux comparator compare the actual values of torque and flux with the reference values for torque and flux to Determine the optimal switch position. It can be seen that it is through the torque and magnetic flux measurement, instantly adjust the inverter circuit switching state, and then adjust the motor torque and magnetic flux, in order to achieve the purpose of precise control.
- Q:Which machines are used for the frequency converter
- Used on a motor that needs to change the speed to change the power.
- Q:Laptop computer about electricity no electricity, is the power adapter problem?
- To judge this is very simple:
1. The computer is in the battery state to see if it works properly. If it does not work, the battery has a problem
2. Remove the battery from the computer with a power adapter to see if it is working properly. If not, there is a problem with the power adapter
3. If the two states can work that is the computer charge management part of the poor contact and other issues.
- Q:HP laptop power adapter how to open
- That thing is not generally no screws, is sticky together. If you want to split, can only use the blade along the seam a little bit of open
