product description

●The natural power factor of high-power intermediate frequency furnaces is between 0.8 and 0.85, with large reactive power requirements and high harmonic content. ●The natural power factor of the low-power intermediate frequency furnace is between 0.88 and 0.92, and the reactive power demand is small, but the harmonic content is very high. ●The grid side harmonics of the intermediate frequency furnace are mainly 5th, 7th and 11th. In order to ensure the power quality, it is necessary to take harmonic suppression measures and compensate reactive power at the same time. According to my country's power quality standards and our company's research results in harmonic control in recent years, broadband filter technology is used to set filter circuits for the characteristic harmonics generated by intermediate frequency furnaces, absorb harmonic currents, improve power quality, and completely solve the problem. Intermediate frequency furnaces, UPS power supplies, CNC machine tools, inverters and other sensitive loads are damaged due to power quality problems. In addition, it can shorten the smelting time and bring energy-saving benefits to users. The connection of the intermediate frequency furnace filter can use high-voltage filtering or low-voltage side local filtering. According to the harmonic principle and harmonic power flow analysis, installing on the low-voltage side has obvious advantages, mainly as follows: 1) Harmonic current is absorbed at the nearest low-voltage side to avoid flowing into the high-voltage system and reduce losses and failures on the rectifier transformer. 2) For the unit filter of a single transformer, the control method is simple and reliable, and it can be switched dynamically according to the load change of the intermediate frequency furnace. 3) The low-voltage filter equipment installer is easy to maintain 4) The price of low-voltage filtering is lower than that of high-voltage filtering. Environmental conditions of filter equipment Installation location: indoor Design indoor maximum temperature: +45°C Design indoor minimum temperature: -15°C Design indoor relative humidity: 95%/
