Abstract

The invention discloses a voltage and current double-closed-loop direct-current speed regulation system assessment device, which comprises a voltage and current double-closed-loop speed regulation circuit (I), a supplementary circuit (II) and a fault debugging panel (III), and is characterized in that wires (wherein dotted lines are in non-electrical connection) are connected between the voltage and current double-closed-loop speed regulation circuit (I) and the supplementary circuit (II) and between the voltage and current double-closed-loop speed regulation circuit (I) and the fault debugging panel (III) according to electrical lines, fault points K1 to K5 are arranged in the voltage and current double-closed-loop speed regulation circuit (I), and the fault points are connected with a fault switch on the fault debugging panel through a relay in the supplementary circuit (II). The comprehensive capabilities of fault searching, fault analysis, fault solving and the like of students forthe voltage and current double-closed-loop direct-current speed regulation technology can be cultivated.

Description

technical field [0001] The invention relates to an assessment device for a double-closed-loop direct-current speed regulation, in particular to an assessment device for a voltage-current double-closed-loop direct-current speed regulation system. Background technique [0002] Double closed-loop DC speed regulation is an important aspect of the application of power electronics technology. In traditional vocational education, it focuses on the more important aspects of system debugging, waveform observation and actual fault analysis in voltage and current double closed-loop DC speed regulation. The existing training conditions in the market cannot be satisfied, which makes students have relatively large learning obstacles in voltage and current double closed-loop DC speed regulation. [0003] Therefore, there is an urgent need to develop an assessment device for voltage and current double closed-loop DC speed control systems, which can improve students' comprehensive debugging...
