Description

Conditions for middle frequency power supply:

• The sea level height: 3000m
• Environment temperature: -2≤T≤40
• Air relative humidity:≤80%
• Installed room should be well ventilated,with no conductive dust and without corrosive gases
• The place is without violent vibration and impact and explosion hazard
• Cooling water is 1-2mg/cm2, 7PH8, Device shall not be used under the condition of condensation.

Voltage should be a sine wave, Harmonic distortion is less than 5%, Input is three-phase AC, line voltage 380v, Continuous voltage fluctuation range is not more than ±10%, The frequency of the power grid voltage change is not more than ±2% (That should be between 49 to 51 hz), And three-phase voltage unbalance degree should be less than±5%.

The selection of Medium-frequency power supply main circuit thyristor rectifier left sufficient margin, As equivalent to the conventional power 1.2- 1.3 times that of the same capacity selection thyristor, making the overload capacity and reliability has a significant improvement.

Rectifier control uses a new generation of full digital trigger technique. Three-phase synchronous signal is directly introduced from Photoelectric isolation device of 2500v main return path into control panel and realizes automatically balance of strict industrial frequency three-phase current.

Perfect and reliable automatic adjustment system which consists of current, voltage, resistance, four of the inverter triggering before angle regulator, current and voltage automatically realize the constant power regulation, impedance controller can make the power supply and load in the smelting process which is always in a state of optimal operation.

The central control panel adopts single board structure, which is of  high level of integration, three-phase synchronous, rectifier trigger and control, inverter trigger and control, regulation and protection, pulse rectifier transformer assembled on the same piece of the central control panel with strong interchangeability and convenient change.

Principle

This complete set of middle frequency induction heating pipe bending machine adopts electron magnetic theory which can converts the 3 phase power frequency into single phase middle frequency power energy. The work-piece is put into the circumanstance of vacuum and protective gas, and the alternating magnetic field will generate eddy-current loss and produce huge heat, thus it can meet the heating requirement of smelting, diathermanous, quenching and bending.

Application

The pipe bending machine is widely applied in many industrial fields:

Areospace

Oil and gas

Steel construction

Boiler

Ship-building

The pipe bending machine can be used for round, square steel pipes as well as joist.
