Abstract

The invention provides a variable frequency dielectric loss tester comprising detachable lifting type handles which are arranged at the two surfaces of the upper side of the tester and can be freely detached. The side surface of the detachable lifting type handles is provided with a high voltage output socket. The lower end of the detachable lifting type handles is provided with a backlight button. One end of the backlight button is provided with a liquid crystal displayer. The lower end of the liquid crystal displayer is provided with functional buttons. One end of the functional buttons is provided with a U-disk interface. The upper end of the U-disk interface is provided with a high voltage indicating lamp. One end of the high voltage indicating lamp is provided with a power supply input socket. One end of the power supply input socket is provided with a power switch. The upper end of the power switch is provided with a printer. The upper oblique end of the printer is provided with a grounding connecting post. One end of the grounding connecting post is provided with a self-excitation method current output end. The upper end of the self-excitation method current output end is provided with a standard capacitance input socket. The upper end of the standard capacitance input socket is provided with a test object input socket.

Description

technical field [0001] The invention relates to a frequency conversion dielectric tester, in particular to a frequency conversion dielectric loss tester, which belongs to the technical field of frequency conversion dielectric loss test. Background technique [0002] The frequency conversion dielectric loss tester is a high-precision testing instrument for testing the dielectric loss tangent and capacitance of various high-voltage power equipment on-site or in laboratories such as power plants and substations. The instrument is an integrated structure with built-in dielectric loss test bridge, variable frequency and voltage regulating power supply, step-up transformer and SF6 high stability standard capacitor. The digital notch technology is used to avoid the interference of the power frequency electric field on the test, and fundamentally solve the problem of accurate measurement under strong electric field interference. At the same time, it is suitable for occasions where ...
