What is the cause of frequent tripping of full-color LED display?Such as the line damage, leakage protection itself problems and misoperation, plus

The leakage protector is not arranged according to the actual power consumption, which will cause frequent tripping of the leakage protector.How to deal with this situation?

1. Improper distribution of leakage protector

The layout of leakage protector is unreasonable, because of the particularity of the LED full-color display screen when installed, such as circuit damage, and other reasons, as well as leakage protector

Due to its own problems and misoperation, the leakage protector will frequently trip.

How to fix it?In addition to strengthening the management, the leakage protector should be arranged reasonably according to the actual situation.Leakage protector is used as a protection

Total protection of electrical fire hazard and electrical short circuit, rated leakage action current can be selected between 200 and 500mA, rated leakage action time is available

Choose 0.2 ~ 0.3 s.

2. No effective secondary or tertiary leakage protection

[led display screen] because there is no effective secondary or tertiary leakage protection within the protection range, the final level leakage protector in the switch box is used

The main protection of electrical equipment, if the final level leakage protector is not installed, damaged or improperly selected, it may lead to frequent tripping of the upper leakage protector.thus

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.

Three: the electric load cannot be completely balanced

The leakage protector we use at present, whether electromagnetic or electronic, adopts the magnetic induction voltage transformer to pick up the main circuit of the electrical equipment

In the leakage current, three - phase or three - phase four - wire in the magnetic ring is impossible to arrange complete equilibrium.The three-phase power load of the LED full-color display cannot be completely flat

In the case of large current or high overvoltage, a certain electromotive force can be induced in the magnetic ring with high permeability, which is large to a certain range

Degrees will cause the leakage protector to trip.

In addition, the leakage protector has an unspecified area between rated leakage action current and rated leakage nonoperating current, leakage protection

The leakage current of the protector fluctuates in this area, which may cause the leakage protector to trip erratically.

Iv. Unreasonable selection of protector [shenzhen LED display screen price]

The improper selection of the leakage protector may lead to its open trip.Rated leakage action current used in switch box is over 30mA or more

It is the leakage protector over two times the rated current of the electrical equipment, and the leakage protector with delay type is selected, because the rated leakage action is electric

When the flow increases or the protection sensitivity decreases, the superior leakage protector may act, thus causing tripping disturbance.

To sum up, it can be known that the LED full-color display‘s empty tripping is caused by a variety of reasons, so in order to solve the problem of frequent electric leakage, first of all

It is necessary to arrange the leakage protector reasonably, reduce the protection scope of the secondary or tertiary leakage protector, and select the wiring and leakage protector correctly.

In addition, we need to strengthen power management and improve the comprehensive quality of power users, which can not only improve electricity safety but also solve problems

The leakage protector frequently trips.[LED display price]
