Description

technical field [0001] The invention relates to the technical field of power capacitors, in particular to a reusable voltage withstand test device for power capacitor elements. Background technique [0002] Two conductors that are close to each other, with a layer of non-conductive insulating medium in between, constitute a capacitor. When a voltage is applied between the two plates of the capacitor, the capacitor will store charge. The capacitance of the capacitor is numerically It is equal to the ratio of the amount of charge on a conductive plate to the voltage between the two plates. Capacitors play an important role in tuning, bypassing, coupling, filtering and other circuits. It is used in the tuning circuit of transistor radios. It is also used in the coupling circuit and bypass circuit of color TV. [0003] In the production of existing capacitors, it is often necessary to conduct withstand voltage tests on them. Generally speaking, the method used is to apply volta...

Problems solved by technology

[0003] In the production of existing capacitors, it is often necessary to conduct withstand voltage tests on them. Generally speaking, the method used is to apply voltage to the capacitor plate, and the withstand voltage performance of the capacitor can be obtained by increasing the voltage until it is broken down. However, The withstand voltage test devices currently on the market are cumbersome to test, and it takes a lot of time to connect the circuit, and during the measurement process, some capacitors are prone to explosion when they break down, which may cause injuries to testers, which is very unsafe
