The following two points should be kept in mind when applying stone processing inverters:


(1) Use environment. Inverter has higher requirements for ambient temperature, and it is also a device with large heat generation. When using high-power inverters in stone processing, when considering cooling, we must consider the heat of the inverter. Generally, according to the capacity of the inverter, 3 to 4% of the power is calculated by the calorific value of the inverter. . The rated capacity of the inverter in the stone processing industry is marked for a certain use environment. The inverter's operating temperature is generally required to be 0 ° C to 55 ° C, preferably controlled below 40 ° C, and the relative humidity should be controlled to 20% to 90%. .




       The rated current of the inverter in the stone processing industry is based on a certain altitude, rated voltage, and rated carrier frequency. If it exceeds the regulations, it will cause the inverter to be derated. In the selection of inverter for stone processing, the capacity should be modified as follows: when the altitude is higher than 1Km, the inverter rated current should be reduced by about 6% for each additional 1Km; when the input voltage is increased by 2%, the inverter rated current It should be corrected downward by 4%. When the carrier frequency is higher than the rated carrier frequency, the rated current should be corrected accordingly.


(2) External configuration of inverter for stone processing industry. In order to prevent operating overvoltage, it is not suitable to install a contactor between the inverter and the motor. If there is no fast fuse before the internal rectifier circuit of the inverter, a fast fuse that meets the requirements should be externally installed between the inverter and the power supply. An air circuit breaker cannot be used. Instead of fuse
