KGPS IF power supply characteristics

KGPS intermediate frequency power supply is a thyristor intermediate frequency power supply, which is a kind of stop frequency conversion equipment, which uses thyristor components to change the three-phase industrial frequency power supply into a single-phase intermediate frequency power supply. This equipment has strong adaptability to various loads and a wide range of applications. It is mainly used for smelting, heat preservation, sintering, welding, quenching, tempering, diathermy, metal liquid purification, heat treatment, pipe bending, and crystal growth of various metals. .

IF equipment has the following characteristics:

To

1. The power supply cabinet is made of cold-rolled steel plate and sprayed with plastic, and the components are reasonable, which is convenient for equipment, debugging and maintenance. The cooling method is air-cooled or water-cooled.

To

2. The rectifier bridge (KP tube) and inverter bridge (KK tube) are all selected excellent thyristors, and the control circuit equipment is selected with excellent components, which makes the equipment highly reliable and stable.

To

3. The control core of this equipment is divided into two categories, namely, the most advanced constant power control panel in China is used for sweep frequency start (2.6, 3200 and 3206 series intermediate frequency equipment) and the zero-start control panel (2.7 and 2.8 series intermediate frequency equipment) During the entire starting process, the frequency conditioning system and the current conditioning system track the load changes over time, completing the more ambitious closed-loop soft start. This starting method has a small impact on the thyristor and is beneficial to extend the useful life of the thyristor. At the same time, it also has the advantage of simple starting for light and heavy loads.

To

4. Actively adjust the output power during operation, so that the equipment is always in the working condition of maximum output power. Especially for smelting occasions, the smelting speed is effectively improved.

To

5. There is no need for special duty personnel. The operation of this equipment is extremely simple. There is only one power switch and one power adjustment knob. After starting, as long as the power knob is turned to the maximum, the equipment will take the initiative to carry out the rest. When the furnace suddenly increases the material, The equipment will actively adjust the power, and will not show the undesirable phenomena of over-current and over-voltage shutdown top switches.

To

6. Because the smelting speed is faster and the thermal efficiency is high, the unit production is improved, and generally does not show the current shut-off working condition, and all work under the highest DC output voltage (rectified a=00), so the input power factor of this equipment is high, up to 0.94, so there are more significant economic benefits. The average output power can be increased by 10-20%, the melting cycle can be reduced to 2/3 of the original, the unit output can be increased by 1.5 times, and the electricity consumption can be saved by more than 10%.

To

7. The protection circuit of this equipment is perfect, so that the thyristor components are always operating within a safe range, the life span is significantly extended, and the damage rate is greatly reduced.
