Automatic controller for steady-current output of three-phase current

Abstract

The invention discloses an automatic controller for steady-current output of a three-phase current. The automatic controller comprises a three-phase power supply used for providing a three-phase alternating current, a three-phase rectifier used for completing AC-DC conversion, a transformer used for completing DC-DC conversion, a current regulating module used for controlling the output of the three-phase current, a filtering module used for filtering clutter interference, a temperature detection module used for collecting temperature information, a current detection module used for collectingcurrent information, a frequency collection module used for collecting a frequency, and a CPU controller used for data processing, wherein the three-phase power supply is connected with the three-phase rectifier; the three-phase rectifier is further connected with the transformer; and the transformer is further connected with the current regulating module. According to the automatic controller for the steady-current output of the three-phase current, the magnitude of the output current can be automatically controlled, so that the stability of the output current is ensured; the parameters of the output current are guaranteed to be normal through the temperature and frequency collection; and meanwhile, the function of remote control is achieved.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to an automatic controller for steady output of three-phase current. Background technique [0002] The three-phase current is a current that passes through three wires, each wire serves as a loop for the other two, and the phase difference of the three components is one-third of a cycle or a 120° phase angle. [0003] Three-phase AC has many advantages over single-phase AC, and it has obvious advantages in power generation, transmission and distribution, and conversion of electrical energy into mechanical energy. For example, the manufacture of three-phase generators and transformers saves materials compared with the manufacture of single-phase generators and transformers with the same capacity, and has a simple structure and excellent performance. 50% larger, in the case of the same power transmission, the three-phase transmission line can save 25% of non-ferrous metals tha...
