TNS series three-phase automatic ac stabilizer fault phenomena cause analysis and processing method
| Fault phenomena | General analysis of the causes |
Processing method |
| Cannot start |
1, input wiring is not reliable 2, no input voltage |
1, the new wiring, and examined for disconnection place 2, the input connection with the voltmeter measurement without voltage |
| A certain phase without voltage instructions | The terminals to should phase wiring is not reliable |
Check this phase wiring connection condition with usb, measuring whether breakers ohm files |
| Start each phase voltage unbalance, appear too high or low phenomenon | 1, the input voltage is not normal; 2, at the input and output line 3, each phase didn't work properly 4, input line didn't answer the phone or wiring is not reliable |
1, check the power grid is normal; 2, check the wiring, rectify; 3, check the connectors and connection are loose; 4, connect well if didn't answer the phone line (line, when adjustment when a phase output voltage, another phase voltage will follow change) |
| Panel voltmeter instructions imbalance makes voltage | 1, each phase voltage exceed its power grid voltage range 2, load serious asymmetry |
1 of three-phase balancing requirements, such as high load three-phase motor must stop and check grid; 2, adjust every load and try to keep the phase equilibrium. |
| Prepare note | Each phase failure analysis and treatment of similar single-phase series | |
