1T series intermediate frequency furnace

1T parallel intermediate frequency furnace

1

Power Factor

Constant power factor 0.9 6

Power factor 0. 7 -0.92

2

Melting power consumption

580 ±5% kW.h/t (1600°C)

≤6 2 0±5% kW.h/t (1600°C)

3

Resonance mode

Voltage resonance, low loss of line (copper row and furnace ring)

Current resonance, large loss of line (copper row and furnace ring)

4

harmonic

Low harmonics, low pollution to the grid

High harmonics, large pollution to the power grid

5

Start success rate

Start success rate 100%

It is difficult to start the device under heavy load conditions.

6

effectiveness

10%-20% higher

Low efficiency because of low power factor and large harmonic pollution

7

Easy to use

Achieve one-to-one, one-for-two, one-to-three, and other work modes

The parallel resonant power supply can only achieve one-to-one operation mode.

8

protection

Complete protection

Relatively complete protection

9

Material costs

Higher material cost, rectification increases filter capacitance, voltage resonance component parameters select high value

Lower material cost, without increasing the rectifier filter capacitor, a low current value of the parameter selection resonant Component

Description: 1T power factor

The power factor of the series intermediate frequency furnace is high: ≥0.9 6 , because all the thyristors in the rectification part of the power supply are in the fully open state , the rectifier circuit is always in the all-on state, and the rising power is realized by adjusting the voltage of the series inverter bridge . Therefore, the entire operation process (including low power, medium power, high power) can ensure that the equipment is always in a high efficiency stage.

Parallel intermediate frequency furnace power factor is low: ≤0. 92 , because all the thyristors in the rectification part of the power supply are in a semi-open state (adding additional compensation according to the requirements of the national grid). The power regulation of the parallel line is adjusted by the rectification conduction angle, so At low power, the power factor of the power system is very low, generally between 40% and 80%; the high harmonics are large and seriously interfere with the power grid .
