What is the cause of LED display leakage and tripping

1. LED display leakage protector itself has certain limitations Current leakage protectors, whether electromagnetic or electronic, use magnetic induction voltage transformers to collect leakage current in the main circuit of electrical equipment. Three-phase or three-phase four-wire cannot be perfectly balanced in a magnetic ring. The three-phase power load of the LED display cannot be completely balanced.

Under high current or high voltage, a magnetic ring with high magnetic permeability will generate a certain electric potential. If the potential is high enough, the leak protector will trip. The rated current of the leakage protector is greater than the rated current, and the leakage magnetism is large.

The leakage current should overcome the magnetizing force of the magnetic ring itself. Therefore, the rated current of the leakage protector is large, the sensitivity is low, and the failure rate is high. 2. The LED is within the protection range, and the display screen cannot form an effective secondary or tertiary leakage protection. The leakage protector in the switch box is the main protection device for electrical equipment . If the leakage protector is not installed, damaged or improperly selected, it may cause the upper leakage protector to trip frequently.

Because there are many metal conductors and wire connectors on the full-color LED display. If the wires are not well insulated, this usually causes a leak. Also added some outlets.

In many cases, leakage protectors are not installed, which often leads to leakage. Only by forming an effective secondary or tertiary leakage protection mode within each protection range can the frequent tripping of the leakage protector be effectively reduced. 3. The layout of the leakage protector is unreasonable, resulting in tripping. Mistakes, line damage, damage to the leakage protector of the switch box, failure of some electrical appliances to pass through the switch box, inevitable misoperation and rejection of the leakage protector itself, etc. In addition, the leakage protector was not arranged according to the actual power consumption situation, resulting in frequent tripping of the total leakage protector.

There is an uncertain area between the rated leakage operating current and the rated leakage non-operating current of the full-color LED screen leakage protector. When the leakage current of the leakage protector fluctuates in this area, it may cause the leakage protector to trip unstable. LED displays are widely used in economic life and can be used in many enterprises, government departments and institutions. To ensure production and operation, the application unit of LED display should and needs to be the necessary solution for LED display failure .
