1: The output of the inverter is a PWM wave, which contains more high-order harmonics. The variable frequency power sensor performs AC sampling on the input voltage and current signals, and then passes the sampled value through a transmission system such as cable and optical fiber and the digital input variable frequency power analyzer. The digital input variable frequency power analyzer performs ...
Overview of working principle:The main circuit is the power conversion part that provides voltage and frequency regulation power supply to the asynchronous motor. The main circuit of the inverter can be roughly divided into two categories: the voltage type is the inverter that converts the DC of the voltage source to AC, and the filter of the DC loop is the capacitor . The current type is a...
Frequency conversion energy savingInverter energy saving is mainly reflected in the application of fans and pumps. In order to ensure the reliability of production, all kinds of production machinery have a certain surplus when they are designed with power drives. When the motor cannot run under full load, in addition to reaching the power drive requirements, the excess torque increases the...
Given wayThe common frequency setting methods of frequency converter are: operator keyboard setting, contact signal setting, analog signal setting, pulse signal setting and communication method setting. These frequency setting methods have their own advantages and disadvantages, and must be selected and set according to actual needs.Related question and answerFrequency converterThe frequency...
1. OvercurrentOvercurrent is the most frequent phenomenon of inverter alarm.1.1 PhenomenonWhen restarting, it will trip as soon as the speed is increased. This is a very serious phenomenon of overcurrent. The main reasons are: load short circuit, mechanical parts stuck; inverter module damaged; motor torque is too small and other phenomena caused.It jumps after power on. This phenomenon cannot be ...
We can understand the energy internet from two dimensions: information level and physical level. From the information level, the energy internet can be simply regarded as the application of the information internet in energy, meaning the information internet for energy, but this understanding is very one-sided. From a physical point of view, various energy networks such as power grids, natural gas...
With the continuous development and improvement of frequency conversion technology, its excellent power saving performance, good starting characteristics and various protection functions have been well reflected in the enterprise, which has saved energy, reduced costs and increased the production of the enterprise. ASD.1. Features of the inverterFrequency conversion speed regulation is the best...
China's inverter market is currently in a period of rapid growth and is widely used in air conditioning, elevators, metallurgy, machinery and other industries. According to statistics, in the past few years, China's inverter market has maintained a growth rate of 12%-15%, this speed has far exceeded the GDP growth level in recent years, and at least in the next 5 years to maintain 10% The ...
In the process of maintenance, we often encounter the situation that the inverter of the customer is damaged because it is placed for too long. It sounds incredible, but it is indeed a very frequent situation. If the inverter is damaged and repaired due to improper storage at ordinary times, it will really cost money and affect the normal operation of the company. What problems should we pay...
1. The interference of the inverter to the microcomputer control boardIn the control system using frequency converters, most of them use microcomputers or PLCs for control. In the process of system design or transformation, we must pay attention to the interference of frequency converters on the microcomputer control board. Due to the poor process level of the microcomputer control board designed ...
