1. The product features high power factor for the power grid. The medium frequency power supply is a voltage-type series inverter power supply, where rectification always operates at zero degree, no rectification adjustment is required, and only inverter is adjusted. Therefore, it has a high power factor higher than 0.95 and no high-order harmonics. It provides users with substantial benefits in energy conservation, operation and production for all smelting plants. We guarantee that the power factor of the equipment is always higher than 0.95 under any working conditions.
2. The product saves power consumption. With the series resonant circuit design, the reactive current is small, which greatly reduces power consumption. For a 0.5-ton 300KW medium frequency furnace, melting iron to 1450℃ consumes 680 kWh of electricity, and melting steel to 1600℃ consumes 720 kWh. A 0.5-ton parallel thyristor medium frequency furnace needs a 500KW transformer to drive, while a 0.5-ton series inverter medium frequency furnace can work normally with only a 300KW transformer, and the power consumption is very low. Calculated over a long term, the saved capacity usage fee can reach more than 100,000 yuan in one year.
3. The product maintains constant power output throughout the smelting process. Compared with parallel inverter medium frequency power supplies, it adopts a different power regulation method: parallel medium frequency power supplies regulate power by adjusting DC voltage, while our product regulates power by adjusting frequency. It is not affected by the amount of furnace charge and maintains constant power throughout the entire smelting process. It shows its superiority especially when smelting non-magnetic materials such as stainless steel, copper, industrial silicon and aluminum. It features faster melting speed, less burning loss of furnace charge elements, better energy saving effect and reduced casting cost.
4. It requires a power transformer with small capacity. Take a half-ton furnace as an example, the half-ton series medium frequency furnace produced by Luoyang Wanle Electric Power Equipment Factory only needs a 300KW transformer with 380V low-voltage side voltage. For ordinary foundry enterprises, a single transformer below 315KW is enough to share power for the furnace, lighting, cranes, water pumps and other power loads. In some regions, power supply departments only require a monthly capacity fee of 28 yuan per kilovolt-ampere for transformers larger than 315KW, so more than 100,000 yuan can be saved every year.
