Led Display Frequency Trip Reason - China

LED Display Frequency Trip Reason

Why does theEvent Rental LED Video Wallfrequently trip? Here is a brief analysis of this:

1 - The layout of the leakage maintenance device is unreasonable

Due to the special nature of theLED Video Panel for Showsinstallation site, such as wiring errors, damage to the leakage maintenance device in the switch box, damage to the line, some electrical appliances have not passed through the switch box, etc., plus the inevitable mistakes of the leakage maintenance device itself.

The movement and refusal, together with the failure to install the leakage maintenance device according to the actual power usage, caused the total leakage maintenance device to frequently trip.

2 - Does not constitute useful secondary or tertiary leakage maintenance within the maintenance scale

The last stage leakage maintenance device in the switch box is the main maintenance of the electric equipment.

If the final stage leakage maintenance device is not installed, damaged or improperly selected, it may cause frequent leakage of the upper leakage maintenance device.

3, the leakage maintenance device itself has certain limitations

At present, the leakage maintenance device, whether electromagnetic or electronic, uses a magnetic induction voltage transformer to pick up the leakage current in the main circuit of the electrical equipment, and the three-phase or three-phase four-wire cannot be completely balanced in the magnetic ring.

4, the selection of leakage maintenance device is not reasonable

The extra leakage current used in the switch box exceeds 30mA or the leakage maintenance device that exceeds the extra current of the electrical equipment by more than twice, or the leakage maintenance device with delay type is used because of the progress of the extra leakage current or The maintenance sensitivity decreased, and the last stage leakage maintenance device still found no action after the leakage;

The starting current when energizing theAdvertising LED Displayis often large, and a large current may cause the leakage maintenance device to trip.

Therefore, power up the display cabinet as much as possible in batches.

Generally, an electromagnetic type leakage maintenance device that is less sensitive to surge overvoltage and overcurrent should be selected; or an electronic leakage maintenance device that is 1.5 to 2 times larger than the extra current is selected, and the extra leakage current of the last stage leakage maintenance should not be greater than 30mA.
