Abstract

The invention discloses a heavy current generator comprising the following units: a voltage regulating module with an input end connected with a power supply and used for regulating the power supply voltage, and using the output end to output the regulated voltage; a transformer module with an input end connected with the output end of the voltage regulating module so as to receive the regulated voltage, the transformer module is used for amplifying current, so the output end of the transformer module can output the amplified current; a digit display module connected with the output end of the transformer module and used for displaying the output current value of the transformer module. The digit display module can display the amplified current value outputted by the transformer module, thus realizing current output value digitlization display; compared with a dial displayed value, the digitlization display value is more accurate, and the reading is convenient and high in accuracy.

Description

technical field [0001] The invention relates to the technical field of electric energy metering devices, in particular to a large current generator. Background technique [0002] The high current generator is a power device with adjustable output of low voltage and high current. It is mainly used in the field of measurement and calibration of instruments and meters, and is also used in the field of testing of overcurrent on relays and relay contacts. It is especially widely used in the factory calibration of the meter. The high current generator can simulate the real current environment and load to achieve accurate calibration of the meter within the full range. Because the technology of high-current generators is relatively simple, there are a large number of such products on the market today. [0003] The stepless voltage regulation and self-coupling technology applied by the high current generator itself limit its own volume and weight. The larger the output power, the l...
