Working principle

The Alstom MCRI1 module board operates based on the principle of magnetic amplifier and is essentially a controllable saturation iron core reactor control module that magnetizes both AC and DC simultaneously. The core working logic is to change the saturation of the iron core through a small DC control signal (with a power of only 0.1%~0.5% of the rated power of the module), thereby adjusting the magnetic permeability and inductance value of the iron core, and ultimately achieving precise adjustment of the current size.

The specific workflow is as follows: Firstly, the module receives parameter setting instructions from the upper control system through the communication interface to determine the target current value; Subsequently, the current signal of the controlled circuit is collected in real-time and fed back to the internal processing unit for comparative analysis with the target value; If there is a deviation, the processing unit adjusts the magnitude of the DC control current by triggering the thyristor, changes the saturation degree of the iron core, and then adjusts the inductance value to correct the circuit current; When the current reaches the target value, maintain the current control state and achieve dynamic balance. Throughout the process, the freewheeling diode plays a role in freewheeling protection, ensuring stable operation of the circuit; At the same time, the built-in monitoring unit of the module continuously monitors the voltage, current, and other status of the circuit. Once overload, short circuit, or other abnormalities occur, the protection mechanism is immediately activated to cut off the circuit.

Precautions

-Installation environment requirements: It should be installed in a well ventilated area to ensure smooth heat dissipation, avoid air vents being blocked, and prevent module damage due to overheating; Stay away from hazardous environments such as flammable, explosive, and corrosive gases, and avoid direct sunlight and rainwater erosion.

-Electrical connection specifications: strictly follow the wiring diagram for wiring, ensure correct connection of positive and negative poles, and avoid reverse connection; Check the wiring terminals to ensure that there are no exposed copper wires and prevent leakage and short circuit accidents; After the wiring is completed, it is necessary to test the continuity and insulation of the circuit, and only after confirming that there are no errors can it be powered on.

-Power access requirements: The power supply must meet the rated voltage requirement of 24V DC to avoid high or low voltage; The fluctuation range of the power supply should be controlled within ± 10%, and if necessary, a regulated power supply should be configured to ensure the normal operation of the module.

-Operation and debugging: Before debugging, it is necessary to be familiar with the module parameters and control logic, strictly follow the operating procedures for parameter settings, and avoid blind debugging that may cause module failures; During the debugging process, real-time monitoring of parameters such as current and voltage is required to ensure that the adjustment effect meets expectations.

-Maintenance and upkeep: Regularly clean the module, remove surface dust and debris; Check if the interface connection is secure, free from looseness, oxidation, and other conditions; Regularly verify and adjust the accuracy, and calibrate in a timely manner if any deviation occurs; Avoid equipment maintenance during thunderstorms to prevent module damage from lightning strikes.

-Fault handling: If the module malfunctions and alarms, the power should be cut off first, the circuit and load should be checked for normal operation, and external faults should be eliminated before restarting the module; It is prohibited to disassemble or replace components while the module is live. Maintenance must be carried out by professional technicians.
