WiFi technology-based fluorescent lamp circuit power factor improving experiment apparatus and experiment method therefor

Abstract

The invention relates to a WiFi technology-based fluorescent lamp circuit power factor improving experiment apparatus for an electrical and electronic experiment curriculum and an experiment method therefor. Via software on an intelligent mobile phone, a compensation capacitor module switch in an experiment apparatus wire connection and measurement platform is controlled to act, a capacitor is enabled to be connected to or disconnected from a circuit, and therefore power factors of the circuit can be changed. A student does not need to repeatedly perform experiment operation of electricity turn-off, clearing, wire connection and electricity turn-on when the capacitor which is connected in the circuit in parallel needs to be changed, experiment time can be saved, and much time can be left for analyzing experiment objects in experiment classes; when a fluorescent lamp circuit is switched on, the capacitor is controlled by the student to be connected to or disconnected from the circuit via the software installed on the intelligent mobile phone, the capacitor connected in the circuit in parallel while direct contact with the experiment circuit is not needed, reading change of a power factor meter can be observed in real time, and electricity utilization safety risks can be lowered.

Description

technical field [0001] The present invention relates to an experimental teaching device and an experimental method for improving the power factor of fluorescent lamp circuits used in electrical and electronic experimental courses, and in particular to an experimental teaching device and an experimental method for improving the power factor of fluorescent lamp circuits in electrical and electronic experimental courses based on WiFi technology. experimental method. Background technique [0002] At present, in the teaching of electrical and electronic experiments in colleges and universities, an old-fashioned fluorescent lamp circuit with a coil ballast is used as an inductive load, and the power factor of the circuit is changed by connecting a capacitor in parallel. Mainly by manually connecting capacitors into or out of the circuit to change the power factor of the circuit. The disadvantage of this method is that the capacitor needs to be manually connected to or cut out of ...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is that the capacitor needs to be manually connected to or cut out of the circuit, which requires the students to cut off the power supply, remove the wiring on the experimental circuit (cut out the original capacitor connected in parallel to the circuit), A new capacitor in the circuit), check the connection, turn on the power, and measure the experimental data of the new capacitor connected in parallel on this basis. For this, the students paid time and increased the time overhead of the experimental operation
