Compared to traditional power generator sets, medium-frequency power sources offer advantages such as variable frequency, high efficiency, low noise, compact size, lightweight, easy installation, and simple operation and maintenance. However, they also have certain drawbacks; the harmonics and noise generated by high-power sources can interfere with the power grid and the environment, necessitating measures to address this issue.
Under rated voltage or load, the output power can be smoothly and continuously adjusted, with a range of 5% of the rated power. It can prevent overvoltage during switching operations such as QF switching and RS fusing. When the output voltage exceeds 1.1 to 1.2 times the high output voltage or exceeds the voltage setting value, the overvoltage protection system activates, causing the device to automatically shut down and emit an alarm signal. The meter box overvoltage indicator light illuminates. When a direct short circuit occurs in the inverter bridge, the protection system acts immediately.
The device automatically shuts down and emits an overcurrent indication signal, illuminating the instrument cabinet's overcurrent indicator light when the output current exceeds the set value. The protection system also causes the device to automatically shut down and emit an overcurrent indication signal, lighting the instrument cabinet's overcurrent indicator light. If the water-cooling system's working pressure falls below a certain level, the machine will automatically shut down and light up the water pressure indicator light on the panel. The machine is equipped with flow and pressure limiting stages to keep the input current and output voltage within the set values.
