Abstract

The invention discloses a large current generator for current transformer calibration and a control method thereof. The large current generator for current transformer calibration comprises a main ACcontactor, a large current generator, a rectifier and filter circuit, a forward AC contactor, a negative AC contactor, a sampling resistor and a centralized controller. The centralized controller is adopted to realize that the current is continuously adjustable between -1200 A and + 1200 A, -1200 A -+ 1200 A DC signals and reference signals with the accurate current magnitude can be provided for current transformer calibration, and the problem of accurately calculating the remaining capacity of the battery can be better solved.

Description

technical field [0001] The invention relates to a large current generating device for calibrating current transformers and a control method thereof, which can be widely used in the fields of manufacturing electric vehicle lithium batteries and current transformers. Background technique [0002] With economic development and people's increasing requirements for the living environment, energy conservation and emission reduction has become a problem that the industry must face. According to the global carbon emission survey statistics, the carbon dioxide emitted by automobile exhaust is 24%, second only to the emission of traditional energy processing and reuse. In the automobile industry, exhaust emissions from traditional fuel vehicles are one of the most important sources of pollution. Compared with fuel vehicles with high pollution and high energy consumption, electric vehicles rely on electric power, low noise, high energy efficiency, and no pollutant discharge. They have...
