Case Details
VT-STQ(0)L three-phase contactless digital control rectifier control device, using a set of fully controlled bridge thyristor power module components to convert three-phase AC380V50HZ voltage into a continuous DC voltage to provide forward excitation current for the lifting electromagnet, while using this component to feedback the residual energy after the material is released from the electromagnet back to the grid. Another set of two-phase fully controlled bridge thyristor power module components converts three-phase AC380V50HZ voltage into another DC voltage to provide reverse demagnetization current for the lifting electromagnet. The working state of the two sets of thyristor power module components is controlled by a microcontroller digital controller. The microcontroller digital controller also controls the system's material suction and release operations, thereby achieving the purpose of controlling the electromagnet's material suction, release, and magnetic adjustment.
Main technical features
1. Three working modes
(1). Constant voltage working mode: output voltage is DC220V;
(2). Magnetic adjustment working mode: output voltage DCOV-DC220V adjustable;
(3). Strong excitation working mode: the lifting moment is DC290V, and the output during the material lifting process is DC200V.
2. Three operating methods
(1). Controller or monitoring box operating method;
(2). Switch quantity remote control operating method (cannot remotely adjust magnetism);
(3). Switch quantity and analog quantity full remote control operating method (can remotely adjust magnetism);
3. Using contactless control, abandoning the traditional DC contactor control for charging and demagnetizing; this results in no electric sparks, no noise, and no mechanical vibration during operation, extending the service life. During demagnetization, the residual energy in the electromagnet is first fed back to the grid, which eliminates the energy consumption method of high-power energy-consuming resistors, and on the other hand, uses a strong excitation field to absorb a lot of material during lifting, and after lifting, uses low voltage to maintain magnetism during transport, thus achieving significant energy savings from these two aspects.
4. Using the latest microcontroller for digital contactless control, function and parameter settings are operated by buttons, fault alarms and interface parameters are displayed on an LCD, and set parameters are automatically stored: from pulse phase shifting, fixed width, to modulation, all are digitized, and the trigger part does not require any adjustment during use, featuring high reliability, strong anti-interference ability, fast response speed, and ease of use. The device has automatic phase discrimination, phase loss protection, soft start on power-up, short circuit, overcurrent, and overvoltage protection functions.
5. Integrated modular design and production, using programmable controller technology, and all selected international or domestic advanced brands, with internal components modularized and reasonably arranged, reducing external wiring and facilitating connection, all components can be replaced in front of the board, making it convenient for user maintenance and repair, with high reliability and safety in operation, and low failure rate.
