1. Check whether the appearance of the inverter is in good condition, including whether the indicator light is running normally, whether the task control function of the operation panel is complete, and carefully observe the appearance of the inverter in the operating state, and do the corresponding recording work; When repairing the inverter, check whether the voltage value and current value exceed the allowable value range, so as to avoid the overload fault of the inverter; If an abnormal situation is found, effective measures should be taken to avoid the expansion of the fault, and try to quickly eliminate the fault within a small range.
2. When repairing the inverter, check whether the power supply equipment is running normally, whether the basic line is damaged, and ensure that the line operation is always in a stable state; Check whether the cooling mechanism itself and the operating state are safe and reliable, and whether the inverter is affected by grease and dust during operation. If too much grease and dust accumulate, it will directly block the operation of the air cooler, resulting in the deviation of the heat dissipation effect of the inverter, resulting in an abnormal increase in the temperature of the Schneider inverter, and causing the operation failure of the inverter. Therefore, the inverter must regularly clean the dust and oil around the cooler to ensure the smooth exhaust of the cooler.
3. During the maintenance of the inverter, detect the heat dissipation and thermal conductivity of the inverter in the running state, check whether the radiator is running normally, do a good job in the daily maintenance of the radiator, clean up the dust on the radiator, and prevent the heat dissipation function of the inverter from being affected by dust accumulation; When installing the inverter, it is necessary to install it in accordance with the relevant specifications, choose to install it in the area of a good operating environment, and eliminate the adverse effects of the harsh environment on the operation of the inverter, especially to avoid installing the inverter in a dusty, humid and corrosive environment.
