Abstract
The invention relates to a current transformer tester, which comprises a voltage booster, a current booster, an AC/DC (alternating current/direct current) converter, an analog channel and a microcomputer data analysis device. The analog channel is provided with a channel switch and is communicated with the AC/DC converter, the AC/DC converter is communicated with a current sampling circuit and is sequentially connected with the voltage booster and the current booster, the current booster is communicated with the microcomputer data analysis device, and the microcomputer data analysis device is respectively provided with the printing device and the display device. The tester is provided with a system power supply, no external switching is needed, and the input voltage is set automatically in the instrument. Due to the voltage booster and the current booster, the current transformer tester has high output power and a small size, can be carried conveniently and can be used and operated easily. The maximum current can reach 600A, and the maximum voltage can reach 1000V. The tester can also be used for determining the polarity of the transformer.
Description
Technical field
The present invention relates to the instrument of a kind of relay protection test current mutual inductor volt-ampere characteristic, no-load voltage ratio test and polarity discriminating, relate in particular to a kind of current transformer tester.
Background technology
At the scene during the measuring current mutual inductor, need standard current transformer, current lifting device, load box, Regulation Control case and big current lead at present, big, the complex operation of working strength when making test easily, work efficiency is lower.
Summary of the invention
The present invention provides a kind of simple in structure, easy to operate, current transformer tester that adaptability is good in order to overcome the above problems.
Technical scheme of the present invention is: include stepup transformer, current lifting device, AC/DC transducer, analog channel, Microcomputer Data analytical equipment; Described analog channel is provided with channel switch; And communicate with the AC/DC transducer, described AC/DC transducer communicates with current sampling circuit, and is connected in order with stepup transformer, current lifting device successively; Current lifting device communicates with the Microcomputer Data analytical equipment, is respectively equipped with printing equipment and display device on the Microcomputer Data analytical equipment.
