[0047] Working Principle: This utility model is used for automatic testing of no-load loss and no-load loss sound level of different iron core finished products. The operator calls the production line via an industrial control computer to deliver iron cores. The production line control system collects information and interacts with the production line conveyor system, transferring the iron core to be tested from the surface drying and curing module to the test inter-laboratory buffer position. When the iron core tray is transferred to the test room, the test room door automatically opens, and the iron core is transferred to the test station via a conveyor line and a transfer trolley.

[0048] After the transfer trolley arrives at the test station, the operator uses a handheld control handle to operate the hoisting mechanism to suspend the iron core. After the operator completes the wiring and adjusts the position of the sound level detection probe, the test is carried out automatically.

[0049] After the test is completed, the iron core is manually lowered onto the transfer tray. The transfer trolley carries the iron core tray and moves the iron core to the buffer station of the test station. When the next product enters the test station, the doors on both sides of the test station open automatically, completing the exit of the iron core from the buffer station.

[0050] Meanwhile, labels and test reports are printed manually, and the test information is uploaded to the factory's MES system through the production line control system.

[0051] The testing is a comprehensive test of the finished iron core after spraying. The testing equipment is compatible with the testing of all products and can automatically complete all test items after a single wiring.

[0052] Process flow description of the automatic measurement device for no-load loss of iron core:

[0053] The product is automatically transferred to the testing station by the conveyor line. The testing device identifies the transformer by scanning the code and calls up the core parameters required for the test sample from the database. The core test wires are connected manually. The hoisting device lifts the core to the designated height. The voltage is automatically increased to complete the no-load test.

[0054] The system integrates the control system, frequency converter, power analyzer, and wiring device into one unit, completing the core loss test with a single click. It features intelligent control, automatic data locking, and result calculation. Test results are uploaded to the MES system, and non-conforming products automatically trigger manual re-inspection.

[0055] The system can automatically perform no-load tests, measuring no-load losses, no-load current, line voltage, phase voltage, RMS and average voltage values, average three-phase voltage, current, power, power factor, frequency, and other parameters. It uses a 3-wattmeter for measurement and features automatic voltage boosting, automatic data tracking and locking, overcurrent and overvoltage protection, data storage, data printing, data export, and automatic database upload functions. Test data can be retrieved via the core ID, and test reports are automatically generated.

[0056] Description of the process flow for the automatic sound level measurement device for iron core:

[0057] During the sound level test, the core no-load loss test state is always maintained. Test microphones are used and the test microphones are fixed on the trolley of the hoisting system with tooling brackets. The distance between the microphone and the test object can be manually adjusted. The sound level detection system controls multiple sound level meters to collect data with one click and uploads the data to the transformer detection information management system for automatic calculation. One-click acquisition and automatic calculation can be achieved. There are 12 microphones.

[0058] Test results are automatically uploaded to the MES system, and non-conforming products automatically trigger manual re-inspection. An automated testing / manual re-inspection device is designed, incorporating ergonomic design and necessary tooling.

[0059] The opening and closing of the sound level chamber door is controlled by a dedicated human-machine interface. The human-machine interface has management permissions, and unauthorized personnel cannot enter the system to perform operations. Each entrance and exit is equipped with a photoelectric system to ensure safety and measures to prevent unauthorized personnel from entering. There are interlocking devices to prevent people from entering when the test area is powered on. The test room is equipped with a high-definition camera and microphone to ensure that test personnel can monitor the test samples from the control room.

[0060] The control system of all automatic doors in the sound level chamber is interlocked with the testing system. When the sound level chamber door is open, the testing system cannot be powered on, and when the testing system is powered on, the electric door of the test chamber cannot be opened. Limit switches are installed on the manual small door of the test chamber and are interlocked with the testing system. When the testing system is powered on, if the small door of the test chamber is opened, the system stops outputting and alarms. When the small door of the test chamber is open, the testing system cannot be powered on.

[0061] A low-noise solid-state drive computer is used to measure, control, and calculate the power supply for noise testing. This ensures that the computer does not generate acoustic interference during noise testing.

[0062] After each test is completed, the results are automatically displayed and analyzed separately. If the data is satisfactory, it is automatically saved. If the data is abnormal, the test is retested, and the retest data will eventually overwrite the previous data on the screen.

[0063] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
