General cold storage tripping reason may be the line insulator reduces, or cold storage insulator reduces.
General cold storage will be installed leakage switch, if there is once the voltage is unstable, cold storage leakage switch will be tripped, which can be judged to be the cause of the cold storage causes tripping, specifically what is the cause of that component has to ask a professional maintenance master door-to-door testing to know. If the total switch tripped, the cold storage did not trip, that is a load problem or line insulator reduced, also said earlier if the load problem, the total gate will be hot, if not even if the line problem.
If the cold storage itself is not installed leakage switch, and the main switch tripped, this phenomenon, using the exclusion method, the cold storage outlet unplugged, the switch down the line pick. Then measure the line insulation. Use a shaking table to measure the insulation between the ground and the working line with the cold storage, if the insulation is reduced, then the number of trips will generally increase gradually over time.
If the trip is caused by the cold storage there are two possibilities, the first is that the cold storage requires more power flow than the total electrical switch and the total switch is too sensitive, the second is that the insulation inside the cold storage is reduced, with an electrician’s pen you can test the outside of the enclosure to see if there is any power.
