SBW series high-power power voltage SBW series fault phenomena of high-power electric voltage stabilizer fault phenomena cause analysis and processing method
| Fault henomena | General analysis of the causes | Processing method |
| Cannot switch on the | 1, input cord sequence error or grid abnormity; 2, machine the air inside switch is not close brake or damaged. | 1, replaced any two cables or check whether the power circuit normal (sequence protector, correct sequence lights proof can boot); 2, close brake or replace air switch |
| Cannot regulator | 1, sampling transformer bad; 2, control circuit board bad; 3, motor damage; 4, mechanical system failure. | Repair or replace |
| Regulators single-phase operation | 1 and travel limit switch often closed contacts open or damage; 1, manual/an automatic transfer switch contacts damage; 2, the panel KC1, KC2 lift pressure on the electrical appliances. | replacement |
| No voltage output | 1, stop button SB1 often closed contacts open-circuit voltage 2, SB2 contacts damage; button 3 and the Lord back to the road damage. Contactors KM | replacement |
| Often appear tripping |
1, control PCB over-voltage value not tuned; 2, control PCB resistance change values. |
Professional personnel adjustment or repair |
