A capacitive release test device

Abstract

This utility model discloses a capacitive release test device, including an AC voltage source U s The system comprises a high-precision capacitor module M1, a basic capacitor module M2, a bleeder resistor R, a single-pole miniature circuit breaker QF3, and a single-pole miniature circuit breaker QF4. The high-precision capacitor module M1 includes a single-pole miniature circuit breaker QF1 and a pF-level capacitor C. P Single-pole miniature circuit breaker QF2 and μF-level capacitor C s The basic capacitor module M2 includes a circuit board B, on which several ceramic plate slots Vu are arranged. Each ceramic plate slot Vu is connected to the positive lead p+ of the positive copper claw T+ and the negative lead p- of the negative copper claw T-. This utility model discloses a capacitive release test device that achieves a large capacitance value of over 86nF through the parallel design of 17 ceramic capacitor cells with different capacitance values. The capacitor cells are arranged in a plug-and-play manner to form the basic capacitor module M2, meeting the 27 capacitance values ​​required for capacitive release tests of electrical appliances from 12V to 600V.
