The primary reason for leakage of electricity from a CNC EDM machine may be that the equipment is connected to a ground wire with excessive resistance or that the ground wire is not properly installed. As a guarantee for the safe operation of the equipment, a poor connection or excessive resistance will result in the current not being able to be channeled into the earth properly, thus triggering the phenomenon of power leakage. Therefore, regularly checking the connection status of the ground wire to ensure that its resistance value is within the specified range is a key measure to prevent leakage.
Insufficient insulation strength of the power transformer inside the equipment is also a common cause of leakage. Power transformer as a key component of electric energy conversion, its insulation performance is directly related to the safety of the equipment. If the insulation material is aging, broken or not reasonably designed, it will lead to current leakage to the equipment shell, increasing the risk of electric shock. Therefore, strengthening the insulation testing and maintenance of the power transformer to ensure that its insulation strength meets safety standards is an important means to prevent leakage.
In addition, damage to the internal components of the CNC EDM machine may also lead to leakage. For example, breakdown between the windings and the shell of the AC motor, leakage of the capacitor shell, etc., may trigger equipment leakage. The damage of these components may be caused by factors such as prolonged operation, high temperature, corrosion, etc. Therefore, regular inspection of the state of the internal components of the equipment, timely replacement of damaged parts, is necessary to ensure the safe operation of the equipment.
Environmental factors should also not be ignored. If the CNC EDM machine is in a humid, dusty and other harsh environments, it may lead to a decline in the insulation performance of the equipment, thus increasing the risk of electrical leakage. Therefore, it is important to keep the operating environment of the equipment dry and clean, and regularly clean up the dust and impurities inside the equipment to prevent electric leakage.
To summarize, the reasons for the leakage of CNC EDM machine are complex and diverse. In order to ensure the safe operation of the equipment, it is necessary to check and maintain the equipment on a regular basis, and find and remove potential safety hazards in time. At the same time, strengthen the safety training of operators to improve their safety awareness and operating skills, is also an important way to prevent power leakage accidents.
