Main faults and handle method
In recent years, with the development of power electronics technology, power semiconductor devices and frequency conversion control theory, frequency converters, as an intelligent control power supply, have been widely used in various industries. In the early 1990s, they were mainly imported brands such as Fuji, Mitsubishi, Siemens, ABB, etc. In the mid-1990s, domestic frequency converters gradually appeared in the market, mainly general-purpose frequency converters. At present, the technology of domestic inverter has gradually matured, and the market share of domestic inverter has gradually increased. As one of the professional manufacturers of domestic inverter, Shenzhen Kangwo Electrical Technology Co., Ltd., after a few years of development, with its superior performance, Kangwo inverter is increasingly accepted by customers. At present, the frequency converters produced by Kangwo Company mainly include the general-purpose G1/G2 series, the dedicated P1/P2 series for fans and pumps, the dedicated ZS/ZC series for injection molding machines, and the high-performance single-phase frequency converter S1 series. Other types of dedicated frequency converters and higher performance vector frequency converters will also be introduced to the market in succession. This article mainly describes the common faults and handling methods of the universal type of the Cornwall inverter in application, so that users can refer to them.
