Farad meter for ultrahigh capacitance detection

Abstract

The invention discloses a Farad meter for ultrahigh capacitance detection, which comprises a Farad meter panel, wherein a Farad capacitance value display is disposed on the Farad meter panel, one side of the Farad capacitance value display is successively equipped with a Farad capacitance range selection switch, a display of a testing voltage and a leak current, a testing voltage selection switch, an inner resistance value display and an inner resistance range selection switch, a capacitance testing button and a capacitance meter reading reset button are respectively disposed under the Farad capacitance value display, a binding post of a tested capacitance is disposed under the capacitance testing button and the capacitance meter reading reset button, one side of the binding post of the tested capacitance is successively equipped with a charging control switch, a constant-current selection switch and a power source switch, and an inner resistance testing button is disposed under the inner resistance value display. The Farad meter for the ultrahigh capacitance detection disclosed by the invention can better satisfy an actual working state of the ultrahigh capacitance, wherein measuring and control data needs not to be treated by intelligent computer processing, the capacitance can be displayed clearly and objectively, the structure is simple, and utilization is convenient.

Description

technical field [0001] The invention relates to the technical field of new energy testing, in particular to a supercapacitance detection farad meter. Background technique [0002] Domestic ultra-large capacitor technology has not yet been popularized. With the R & D and production of foreign companies and domestic key enterprises, most of the existing ultra-large capacitor detection technologies use computer sampling and intelligent calculation in the process of constant current charging and discharging to obtain the technical solution of ultra-large capacitance farad value. The equipment is expensive. The operation is professional, and it is difficult to promote it to more enterprises and departments. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a supercapacitance detection farad meter. [0004] A kind of supercapacitance detection farad meter that the present invention proposes, ...
