Cause Analysis of Submersible Pump 's Trip after Water

The submersible pump was operated normally before it was launched, but it did not trip for 10 minutes after it was launched. In this case the possibility of wire leakage is large. From the signs we will say is diving into the underwater pump leakage. However, in my experience, if the submersible pump leakage, often in the water immediately after the opening of a trip, (one or two seconds). It is advisable to check the wires in the incoming water for damage or joints. Seal of these places there is a bad seepage process, often appear ten seconds, tens of seconds after the trip. This situation is very simple maintenance. If not route leakage, it can only be a leakage inside the pump. Circuit part of the water leakage caused by short circuit after the water. Leakage, and as soon as possible to repair the pump quality is poor, closed lax, the insulation dropped after the water caused by short circuit current increases, resulting in switch tripping. Pump insulation is not enough or the cable connector is not connected
