IGBT energy-saving heating equipment

IGBT energy-saving heating equipment product introduction：

Hunan medium frequency power supply inverter part of the integrated IGBT power components, integrated drive, protection, phase locking and other functions, the use of customised low-inductance composite busbar, high insulation level, low leakage inductance, parallel IGBT even current effect, high reliability of the power components, energy consumption reduced by 10%.

IGBT series resonant power supply dual power supply technology, rectifier full open, high power factor, high harmonics is small; full digital control, all the trigger model through the optical fibre transmission, can automatically adjust the two sets of furnace power ratio and total output power according to the control state, easy to achieve the furnace heating, holding, shutdown switching. Component design is reasonable, thermal simulation of the flow path, high reliability, the device operates at less than 50% of the rated capacity, with a safety factor of 100%. Cabinet for electromagnetic compatibility test, to avoid magnetic interference cabinet overall sealing design, safety and from dust pollution reasonable layout, high electrical efficiency.

The main control board has a perfect double protection mechanism: in the normal operation of the system, the main control board real-time monitoring of DC voltage, DC current, inverter voltage, inverter current, induction coil voltage, electric capacitor voltage and thyristor shutdown time, when one of the values of its preset protection value, the main control board will automatically limit the parameter to continue to change in order to ensure that the system operates reliably and safely.

IGBT energy-saving heating equipment technical performance：

1. energy saving: energy-saving IGBT transistor IF power supply than the traditional SCR IF power supply energy saving more than 20%, the main reasons for energy saving are the following:

①, the inverter voltage is high, the current is small, the line loss is small, this part of the energy-saving 15-18%, energy-saving IGBT transistor intermediate frequency power supply inverter voltage is 2800V, while the traditional silicon controlled intermediate frequency power supply inverter voltage is only 750V, the current is small nearly 4 times, the line loss is greatly reduced;

②, high power factor, power factor is always greater than 0.97, reactive power loss is small, this part can be silicon controlled intermediate frequency power supply energy saving 3% -5%. Due to the energy-saving IGBT transistor IF power supply adopts semi-controllable rectification, rectification part does not adjust the SCR conduction angle, so the whole working process power factor is always greater than 0.97, reactive power loss is small.

2. no high harmonic interference: high harmonics mainly from the rectifier part of the regulator when the silicon generated burr voltage, it will seriously pollute the power grid, resulting in other electrical equipment can not work properly, and energy-saving IGBT transistor intermediate frequency power supply rectifier part of the half-controllable rectification, DC voltage is always working in the apex, do not regulate the conduction angle, so it does not produce high harmonics, will not contaminate the power grid, transformer, and will not interfere with other electronic equipment in the factory. So it will not generate high harmonic, will not pollute the power grid and transformer, and will not interfere with the operation of other electronic equipment in the factory.

3. The power supply adopts series resonance mode, and adopts foreign advanced all-digital control transistor mid-frequency control line to ensure that the transistor is not subject to load changes and always work in the ZCS state. Perfect limitation protection measures to ensure that the equipment can run continuously and stably; Japan's black diamond capacitors to improve the life of the equipment and safe and reliable operation; DC filter circuit to improve the power factor of the system.

4.  the whole system by the full digital control, can achieve power factor correction (APFC), constant power control, temperature control, frequency tracking, zero-power start, voltage, current closed-loop control; fault detection and protection circuits on the lack of water, overheating, overvoltage, overcurrent and other faults of real-time monitoring, alarm display.

5. Automatic control system is installed:

Stable and reliable water temperature detection and control, real-time collection, recording, storage process control data and has the corresponding classification retrieval, query, function.

Real-time detection of the process control effect; in the process of equipment operation, real-time analysis, monitoring and diagnostic equipment to follow the state of the various types of abnormalities in a timely manner Chinese character display prompts, and sound and light alarms.

Convenient and quick operation mode two sets of independent operation control system, one set is commonly used button control system and human-machine interface operation control system. All the control logic is set in the programme, which will not cause human misoperation and damage to the equipment.

According to the needs of the operator can be set password password verification function, production records query, print permission management function.

Clear and friendly operation interface, all kinds of operations at a glance, without rote memorisation of cumbersome operating provisions and regulations can be operated.

Installation of flow sensors, you can realise the flow conditions of each water circuit inside the equipment, and can adjust the flow of each branch according to the cooling requirements of each component, if any water failure, the man-machine interface immediately shows the point of failure, and sound and light alarms, automatically stopping the operation of the equipment, so as to make it convenient for the user to find out the problem point. Completely overcome the traditional equipment to the water pressure as an alarm signal may appear in a waterway blockage equipment is still working, resulting in equipment damage.

Perfect external control interface, can easily achieve external temperature and other closed-loop control.
