消磁热敏电阻器(以下简称热敏电阻器)是彩电中的关键部件之一。当该电阻器加上交流220V高压后,流过电阻器上的电流在几秒钟时间内,迅速从10A左右下降到10mA左右。I-t特性是衡量热敏电阻器的重要电参数,评定热敏电阻器还应有标称电阻值和耐电压特性的测试等。为此,我们试制了热敏电阻器综合测试仪,用于对热敏电阻器的质量分析。 Degaussing thermistor (hereinafter referred to as thermistor) is one of the key components in color TV. When the resistor plus AC 220V high voltage, the current flowing through the resistor in a few seconds time, quickly dropped from about 10A to about 10mA. I-t characteristic is a measure of the important electrical parameters of the thermistor, thermistor evaluation should also have a nominal resistance and withstand voltage characteristics of the test. To this end, we have tried a thermistor integrated tester for the quality of the thermistor analysis.
