Abstract

The invention relates to a three-phase stable-current output automatic controller which utilizes semiconductor devices with control poles and is applied in a control or regulating device for a power source or a power supply system or the like. The three-phase stable-current output automatic controller comprises three single-phase voltage regulators, three single-phase current generators, a sensor, a PLC, a touch screen and a control cabinet. The touch screen and the PLC are arranged inside the control cabinet and are interconnected by means of the serial port communication. The PLC is connected with the voltage regulators via multi-core control cables. The voltage regulators are connected with the current generators via cables. The sensor detects the current output terminal of the current generator via a current transformer and then sends the detection result to the PLC via a mask signal line. The three-phase stable-current output automatic controller has the characteristics of high automation degree, real-time response, rapid response and regulation, stable output, easy and visual operation and clear state display.

Description

technical field [0001] The invention belongs to control or regulation equipment used with a power supply or a similar power supply system using a semiconductor device with a control pole, in particular to an automatic controller for three-phase current steady current output. Background technique [0002] The high current generator is a special equipment designed and manufactured according to the current load test and temperature rise test in the electrical equipment test by the power department and industrial and mining enterprises. The equipment consists of three single-phase voltage regulators, three single-phase high-current transformers and related measurement and control systems, and is used to output stable and equal three-phase currents. The voltage regulator is used to adjust the input voltage of the phase, and output a larger current after passing through the high-current transformer. The control system increases (or decreases) the output current by boosting (or ste...
