What measures should be taken to prevent the LED rental screen from tripping on leakage?
LED rental screen hair in the installation is completed and put into use, in the process of use, sometimes there will be a tripping problem, especially when it rains and thunders in the weather, power leakage tripping this kind of phenomenon is a repeated occurrence. Therefore, in order to prevent LED rental screen tripping, we should take relevant measures to effectively prevent the occurrence of such matters. Then you know in order to preventLED rental screenOccurrence of leakage tripping, what measures should be taken? The following Vishay Technology editorial is for you to introduce:
The following measures should be taken to prevent leakage tripping of the LED rental screen:
1, do a good job of electrical inspection before installation
LED rental screen in the installation should be well protected and inspection, check for broken wiring, leakage protection devices and correct parameters after installation to avoid errors.
2, line installation should be standardized
In accordance with the provisions of the site installation of electricity specifications, LED rental screen installation using power lines need to use three-phase power lines to ensure that the circuit will not have problems, while installing leakage protection system, to do everything. Ground installation location is correct, there can be no repeated grounding phenomenon, to avoid the installation of the line to leave hidden dangers.
3、Use of standardized wires
The larger the area of the LED rental screen, the higher the power consumption, the greater the power consumption, so the more current through the line, so the higher the requirements of the wire. In accordance with the standard, the wire needs to meet three basic requirements: conductive wire for aluminum wire, wire cross-section area through the power flow is greater than the power of the LED rental screen, the insulation requirements of the insulating properties of the insulation layer to reach 2 megohms.
4, the choice of leakage protector
In the market, we use the leakage protector has electronic leakage protector and electromagnetic leakage protector, but no matter which, three-phase or three-phase four-wire system arranged in the magnetic ring will not be all uniformly balanced, so in the current is too large and high-voltage, it will be in the magnetic ring inductance in the generation of electromotive force, when the potential energy is large enough to reach a threshold value will trigger the leakage protector action tripping.
If the rated operating current of the leakage protector more than 30mA or operating current more than twice the rated current of the LED rental screen protector, the action current to increase the chances of triggering the last level of leakage protector action, resulting in tripping. Therefore, in order to avoid the LED rental screen leakage tripping problem, we have to choose the right leakage protector.
In summary, is to prevent the LED rental screen leakage tripping, should take some measures. We do a good job through these measures, you can effectively prevent the LED rental screen leakage tripping, so as to provide users with a better experience.
