Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of battery discharge testing, and particularly relates to a battery discharge testing device convenient for batch testing. Background Technique
[0002] The discharge tester is another novel instrument developed and produced after the partial discharge tester. It is characterized by small size, light weight and easy to carry. The output of the discharge quantity calibrator (calibration pulse generator) is connected to both ends of the test sample, with the red end connected to the high-voltage end and the black end connected to the low-voltage end. Adjust its output discharge quantity, such as 50 PC, and adjust the amplifier gain group adjustment knob to make the discharge quantity meter indicate full scale. At this time, if the discharge quantity meter indicates full scale, it means a discharge quantity of 50 PC. Note that the position of the gain fine adjustment knob should not be moved anymore. (The injected electric quantity of the calibration pulse generator of the partial discharge tester is calculated by multiplying the voltage U indicated on the generator by the injected capacitance C on the matching box, Qo = Cq˙Uq). The measuring box should be as close as possible to the high-voltage end of the test sample.
