1. Detection of fixed resistors. A. Connect the two pen pens (regardless of positive and negative) with the pins at both ends of the resistor to measure the actual resistance value. In order to improve the measurement accuracy, the range should be selected according to the magnitude of the nominal value of the resistance to be measured. Due to the nonlinear relationship of the ohmic scale, its ...

A common phenomenon of frequency converter interference 1. As soon as the inverter of the heat exchange station is opened, the pressure transmitter jumps randomly; 2. In the water supply controlled by the inverter, the pressure transformer is used as the signal to collect the pressure, and the pressure transformer is interfered by the inverter; 3. When the inverter starts the motor, the voltage transformer signal is unstable and beats badly; 4. ...

Fuji Electric inverter has many precautions during use. Here are some methods to learn. 　　The ambient temperature has a great influence on the service life of the inverter. For every 10°C, the service life of the inverter will be halved, so the ambient temperature and inverter dissipation must be solved.

The signal of the catalyst feed control valve of a company's DCS system (distributed control system) intermittently appears OOP (output signal line break) alarm, and the control valve is fully opened instantly, resulting in abnormal fluctuations in catalyst flow, which seriously affects the safe and stable operation of the device. Fault cause analysis and treatment ...

【Question】What is the influence of carrier frequency on inverter and motor? 【Answer】1. The influence of carrier frequency on the output current of the inverter (1) The higher the operating frequency, the larger the duty cycle of the voltage wave, and the smaller the higher harmonic component of the current, that is, the higher the carrier frequency, and the flatness of the current waveform.

After the inverter runs uninterrupted for a long time, the high temperature generated inside has serious hidden dangers to the operation of the inverter, especially in summer. The ultimate operating temperature of the inverter inside the inverter is generally 125 °C, and the temperature of the inverter inverter module and IGBT can sometimes reach 110 °C.

1. Analysis of common faults in the main circuit The main circuit is mainly composed of three-phase or single-phase rectifier bridges, smoothing capacitors, filter capacitors, IPM inverter bridges, current limiting resistors, contactors and other components. Many of these common faults* are caused by electrolytic capacitors. The life of an electrolytic capacitor is mainly determined by the ...
