Jinan frequency converter failure often dismantled parts of the key radiator fan and filter capacitor, the actual reason for everyone to know it together

Radiator fan is the output power control module of general frequency converter, which is the most serious component. The heat generated by continuous work must be discharged immediately. Usually, the service life of the fan is about 10 Kh-40 Kh.

江西快3Converted to 2-3 years of continuous operation of general frequency converter, the primary fan should be replaced. The direct cooling fan can be divided into two or three lines. One line of the second-line fan is positive, the other line is negative. Do not make any mistake when replacing the second-line fan.

江西快3Four-wire fans have a detection line besides positive and negative stages. Be careful when they are dismantled, or they will cause overtemperature alarm of universal frequency converter. Communication AC fans are usually divided into 220 V and 380 V. There is no need to make mistakes in the rated voltage when they are dismantled.

The filter capacitor is also called electrolytic capacitor. Its main function is to smooth DC voltage and absorb low-frequency harmonics in DC. The heat generated by its continuous operation and the heat generated by the universal frequency converter itself will accelerate the drying up of its electrolyte, which directly affects its capacity.

江西快3Usually the life of the capacitor is five years. It is proposed that the capacitor volume be maintained periodically over the years. Usually, the capacitor volume should be replaced when it is reduced by about 20%.http://sx064.com
