AC-omskakelaar bestaan uit 'n verskeidenheid komponente, waarvan sommige geleidelik hul werkverrigting en veroudering na langtermynwerk sal verminder, wat ook die hoofrede is vir die mislukking van die frekwensie-omsetter. Ten einde die langtermyn normale werking van die toerusting te verseker, 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
