Title:
ELECTRICAL CIRCUIT LINE QUALITY DETECTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/004623
Kind Code:
A1
Abstract:
An electrical circuit line quality detection apparatus, comprising two electrical connectors, a load resistor, a switch element, a display module and a control module, wherein the two electrical connectors are inserted into a jack and connected to two power lines; one end of the load resistor is connected to an electrical connector, and the other end is connected to a first end of the switch element; a second end of the switch element is connected to the other electrical connector; the control module is in a detection mode, controls the switch element to turn off, detects peak voltage in a voltage waveform and records same as a maximum open circuit voltage, then controls the switch element to turn on, detects peak voltage in the voltage waveform and records same as a load voltage, and calculates a load current; and according to the maximum open circuit voltage, the load voltage and the load current, a line resistance value is calculated, and a corresponding message is displayed by means of the display module.
