The energy consumption acquisition device is high in sampling frequency, large in test range, high in test precision, moderate in price, simple in structure, convenient in use, capable of monitoring power and energy consumption of various machine tools and wide in applicationprospect in terms of low carbon and energy consumption.

Description

technical field [0001] The invention discloses a device and method for testing and analyzing energy consumption data of a numerically controlled machine tool, belonging to the technical field of energy consumption testing. Background technique [0002] As the basis of all mechanical processing and manufacturing, CNC machine tools consume a lot of electric energy. Accurately calculating the energy consumption of machine tools in the machining process is of great significance and is the first step to realize low-carbon manufacturing. [0003] The CNC machine tool spindle system and each feed system are usually equipped with frequency converters to adjust the speed of the spindle and feed system by changing the voltage and current frequency. The frequency range of the input current of the frequency converter is very wide, which exceeds the measurement range of the power frequency, and the three-phase current is often unbalanced and contains a large number of harmonic components...
