Dynamic testing after normal in the static test result for dynamic test, namely the three electric motors phase induction motor electrical commissioning. Before and after the electricity must pay attention to the following: 1, the water pump price electricity before, must confirm whether the input voltage is wrong, the 380 v power 3 phase induction motor access to 220 v level of frequency converter ac synchronous generator will be Fried machine (Fried capacitors, varistors, module, etc.). 2, check the inverter after sowing mouth has been properly connected, whether there is loose connection, connection exception can sometimes lead small diesel engine to frequency converter failure, serious when a frying machine, and so ac synchronous generator on and so forth. 3, detect fault display content, such as transistors and preliminarily concluded that the failure and the reason. 4, such as fault, not shown first to check whether there is Electric motor abnormal parameters, and the parameter after resetting, the no-load without (motor) start frequency converter, and test the U, V, W three-phase output voltage value. Such as a lack of phase, three- phase imbalance, and so on and so forth, a fault module and driver board, etc. 5, the output voltage is normal (without acmotor2.blogspot.com phase, three-phase equilibrium), under the condition of load test. Test, it's best to full load test.
