एसी इन्भर्टरमा विभिन्न कम्पोनेन्टहरू हुन्छन्, जसमध्ये केहीले बिस्तारै आफ्नो कार्यसम्पादन र दीर्घकालीन काम पछि बुढ्यौली घटाउनेछन्, which is also the main reason for the failure of the frequency converter. In order to ensure the long-term normal operation of the equipment, the following components should be replaced regularly:
2 cooling fan AC inverter power module is the most serious heating device, the heat generated by its continuous work must be discharged in time, the general life of the fan is about 10KH-40kh. According to the AC inverter continuous operation is converted to 2-3 years to replace a fan.
The direct cooling fan is divided into two lines and three lines, one line of the two line fan is positive, the other line is negative, do not connect wrong when replacing; In addition to the positive and negative terminals, the three-wire fan also has a detection line. Please pay attention to it when replacing it, otherwise it will cause the overheating alarm of the AC inverter. Generally, AC fans are divided into 220V and 380V. Do not mistake the voltage level when replacing them. Use and maintenance of three-phase AC inverter
