Special precautions for daily operation of high-frequency induction heating power supply

2021-08-12

Special attention should be paid to operational norms in daily operations:
(1) Two or more people are required to operate high-frequency equipment and a designated person in charge of the operation is required. Wear insulated shoes, gloves, and other prescribed protective equipment.
(2) The operator must be familiar with the operating procedures of high-frequency equipment. Before starting the machine, check whether the cooling system of the equipment is normal. Power can be supplied after it is normal, and operate in strict accordance with the operating procedures.
(3) All machine doors should be closed before work, and electrical interlocking devices should be installed on the doors to ensure that power cannot be transmitted until the doors are closed. After the high voltage is closed, it is not allowed to move freely behind the machine and it is strictly prohibited to open the machine door.
(4) The workpiece should be free of burrs, iron filings, and oil stains, otherwise it is prone to arcing with the sensor during heating. The arc light generated by arcing not only damages vision, but also easily damages sensors and equipment.
(5) High frequency equipment should be kept clean, dry, and dust-free. If any abnormal phenomena are found during operation, the high-voltage power should be cut off first, and then the fault should be checked and eliminated. There must be a dedicated person to repair high-frequency equipment. After opening the machine door, first discharge the anode, grid, capacitor, etc. with an electric rod, and then start the maintenance. It is strictly prohibited to carry out live repair.
(6) When using hardened flame resistant machine tools, safety regulations related to electrical, mechanical, and hydraulic transmission should be followed. When moving the hardening machine tool, it should be prevented from tipping.
