Full color led display frequent trip is what causes? Problem such as line breakage, leakage protector itself and misoperation, and not according to the actual electricity leakage protector for decorate, this will cause the leakage protector the frequent trip. In the face of such situation, how should solve? A: leakage protector layout unreasonable leakage protector layout is unreasonable, due to the particularity of full color LED display installation time, such as broken lines, wait for a reason, and the leakage protector itself and misoperation, this will cause the leakage protector the frequent trip. How to solve? Besides strengthening management, still need the protector according to the actual situation to carry on the reasonable arrangement. Leakage protector as to prevent electric fire hazards and total electrical short circuit protection, its rated leakage current action can choose between 200 ~ 500 ma, rated leakage action time can choose 0. 2 to 0. 三个。 2: there is no effective secondary or tertiary leakage protection because there is no effective within the scope of protection of secondary or tertiary leakage protection, switch box level at the end of the leakage protector is the main protection of electrical equipment, if at the end of the leakage protector is not installed, damage or improper selection, could lead to higher leakage protector the frequent trip. Thus only within the scope of each protection an effective mode of secondary or tertiary leakage protection, can effectively reduce the leakage protector the frequent trip. Three: electric load can't balance of the leakage protector, currently used we either magnetic or electrical is the induction voltage transformer to pick up the leakage current in main circuit, electrical equipment phase or three phase four wire can't arrangement in the circular equilibrium completely. LED full-color displays, also can't completely balanced three-phase electricity load, under the big electrical flow or higher over-voltage, induction in have a very high magnetic permeability of magnetic ring out certain electromotive force, the electromotive force big, will lead to leakage protector trip. In addition, the leakage protector in rated leakage action between the rated current and leakage current action not uncertain area there is a movement, the leakage current leakage protector fluctuation in this area, may result in leakage protector irregular trip. 4: protector selection is not reasonable selection of the leakage protector is unreasonable, could lead to a short trip. Rating of the switch used in the leakage current action more than 30 ma or is more than rated current electrical equipment more than twice the leakage protector, and with the delay type leakage protector, due to the increase of leakage current action rating or a reduction in the protection sensitivity, higher leakage protector can action, which may lead to a trip. Obsession. In conclusion, we can know the LED full-color displays open trip is caused by a variety of reasons, and thus to solve the frequent leakage problems, first of all need reasonable decorate leakage protector, narrowing the scope of the protection of the secondary or tertiary leakage protector, the correct selection of connection and leakage protector. In addition, we also need to strengthen management and enhance the comprehensive quality of electricity, electricity can not only improve the safety of electricity, so can solve the leakage protector the frequent trip again
