SF-GGP-H solid state high frequency induction heating equipment

SF-GGP-H solid state high frequency induction heating equipment

Mitutoyo manufacturing SF-GGP-H solid-state high frequency induction heating equipment from abroad to home for so long, the traditional high frequency equipment base set years of production experience, careful design, strict selection, excellence, repeated experiments took the lead in the domestic manufacturing industry with a high frequency welded pipe work continuously for a long time, the composite resonant mode high frequency of domestic high frequency induction heating equipment.

SF-GGP-H solid state high frequency induction heating equipment is based entirely on transistor inverters. The oscillating component adopts the power template structure composed of MOSFET high-power device. The high power capacitor bank C and the inductance coil L and the reliable protection control circuit form the constant current type inverter, and the full transistor type high-frequency induction heating equipment is adopted.

2. use environment

Indoor installation, equipment grounding is good, the grounding wire color and control tie obvious difference (ground line color is color), its sectional area is > 4mmm2, and the grounding resistance is greater than 4;

The altitude is not more than 1000O meters, otherwise, the rated value shall be lowered;

Ambient temperature is not more than 40 degrees, not less than -10 degrees centigrade;

The relative air temperature is not greater than 85%;

No severe vibration, no conductive dust, no corrosive gases and explosive gases;

Installation inclination is not greater than 5 degrees;

Installed on a well ventilated occasion.

Technical characteristics of 1. cycle soft water cooling system:

1) fully closed cycle cooling: to prevent foreign matter from entering the pipeline and causing blockage of the pipeline.

2) soft water cycle: no scale formation, resulting in pipelines, water-cooled components, water-cooled capacitors, water reactors, etc..

3) energy saving and easy operation

4) the heat exchange efficiency is high

5) soft water consumption is small: only a one-time addition of soft water (distilled water), winter can be added to the amount of antifreeze.

2. power grid requirements:

1) the network voltage should be sine wave, harmonic distortion is not greater than 5%.

2) the unbalance between three-phase voltage shall be less than + 5%

3) the continuous fluctuation range of power network voltage shall not exceed 10%, and the frequency change of power network shall not exceed 3% (should be between Hz)
