Full-automatic nonlinear resistance type resonance eliminator test system

Abstract

The invention discloses a full-automatic nonlinear resistance type resonance eliminator test system, which comprises an electronic voltage regulator, a boosting transformer, a measuring circuit, a resonance eliminator, a measurement and control unit, a signal isolation conversion module, a switching power supply, a main controller and a thermal printer; the working process of the full-automatic non-linear resistance type resonance eliminator test system is as follows: voltage output by the numerical control module passes through the resonance eliminator, the main controller automatically records the voltage and calculates the real-time resistance value of the resonance eliminator, and the printer automatically prints the voltage, current and resistance of the system. According to the full-automatic non-linear resistance type resonance eliminator test system, a resonance eliminator power frequency current and voltage parameter verification method is adopted, a high-voltage sampling signal isolation transformation technology is combined, a volt-ampere characteristic curve graph is drawn while fault prediction is performed on a running resonance eliminator, and the test system adopts a segmented variable parameter measure, so that the resonance eliminator can still maintain the original volt-ampere characteristic in a normal working current section.

Description

Technical field [0001] The present invention relates to the field of monumer test technology, in particular a fully automatic nonlinear resistance meter test system. Background technique [0002] The console is a damping device for eliminating voltage transformers in the circuit, protecting the circuit to prevent the PT high-pressure fuse from fucked, avoiding a power grid failure, its essence is a high-capacity nonlinear resistance, pass through Suppress the surge in the grid protection of high-pressure fuses, due to the current system of professional testing of automatic nonlinear resistance, leading to the quality of the consumer, easy to protect the quality factors of the console itself The grid equipment cannot operate safely, increase the risk of staff maintenance, so it is necessary to test it before installing the fully automatic nonlinear resistance meter installation, to increase the reliability after the harns installation, At the same time, the failure of the harns de...
