Problems solved by technology

However, due to different high-voltage ceramic capacitors, there is a deviation in the length of the electrode leads. During manual measurement, due to the uncontrollable compression force, it will lead to poor contact between the electrode leads and the insertion slot, resulting in inaccurate test results. may lead to misjudgment

Abstract

The invention discloses a Capacitance tester, adapted to different lead lengths, for a high-voltage porcelain capacitor. The tester comprises a detection tool and a gland; the detection tool is connected with a capacitance tester body via a data line and is fixed on a pedestal, and the upper surface of the detection tool is provided with two vertical grooves in parallel; the vertical distance between center lines of the two vertical grooves equals the vertical distance between two electrode leads; each vertical groove is internally provided with a wire plugging duct which can be in plugging cooperation with the electrode lead, and the bottom of each wire plugging duct is fixedly connected to the bottom of the vertical groove via a spring; and the gland is arranged above the detection tool, and the height of the gland can be increased and decreased. According to the structure, the electrode leads of different lengths can be measured, plugging cooperation between the electrode leads and the wire plugging wires is well, and the measuring accuracy is high.

Description

technical field [0001] The application relates to a testing device for capacitor production, in particular to a high-voltage ceramic capacitor capacitance tester that can adapt to different lead wire lengths. Background technique [0002] A capacitor is an energy storage element whose function is to temporarily store electrical energy in a circuit, and it stores energy in the form of charge. In electrical circuits, capacitors are commonly used for tuning, filtering, coupling, bypassing, energy conversion, and time delay. [0003] The structure of a capacitor is composed of two very close electrode conductors. When the voltage in the circuit increases, more charges will be accumulated on the electrodes. Therefore, the higher the voltage or the larger the area of ​​the electrode conductors, the more charges that can be stored The greater the amount, the greater the capacitance value; in addition, the distance between the two electrodes and the dielectric properties of the die...
