【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.

Following the last release of the circuit breaker Q&A, we have received new circuit breaker inquiries one after another, and this time we have selected the questions about the "protection function" with a high interest rate for answers: (1) What exactly is a "protection function"? (2) How should I look at the "action characteristic curve"? (3) When selecting, facing ...

The flow meter is one of the important instruments in the water, petrochemical and other industries, which can be compared with the eye of measurement. For the water conservancy industry, it is of special significance. For example, the addition of chemicals in the water supply industry, if the accuracy of the relevant metering instrument is not high, it will directly affect the quality of water quality.

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 ...

When we are repairing the inverter, we often encounter the inverter that triggers the overvoltage protection, at this time, I often wonder, can the overvoltage protection measures be different because of the overvoltage? (1) For the interrupting overvoltage of the phase-shifting transformer, the resistor-capacitance absorption network and oxygen ...

The localization of high-end instruments has always been the weakness of the domestic equipment manufacturing industry. At this year's National People's Congress and the National People's Congress, this topic was raised by many deputies and committee members, and aroused widespread comments.
