One, IGBT digitized induction heating power inverter Features Overview XD-I series IGBT digitized induction heating power inverter is Hangzhou Xin Ding Technology wholesale adoption of America's leading technology, the introduction of IGBT requirements are based on high reliability, high security, user low failure rate digitizing the induction heater. It is widely used in metal heat treatment, quenching, through heat, melting, welding, heat sets, vacuum devices to gas heating, semiconductor materials refining, plastic heat sealing, baking and purification and other occasions, the use of high-frequency magnetic field generated in the induced current caused by self-heating and heating conductor. Induction heating with a gas burner heating or electric heating, compared with a significant energy saving, non-contact, high speed, high efficiency, simple process, easy to implement automation and other significant advantages. Its working principle is: the 50Hz three-phase power frequency electric rectified, filtered, single-phase inverter for AC current, parallel resonant circuit via the compensation capacitor and quenching transformer consisting delivered to the sensor using the principle of electromagnetic induction eddy reach Sensors placed on the parts Hardening purposes. The device is compared with other manufacturers in the industry, has the following salient features: 1, the overall structure of the European standard, single door, space-saving device to facilitate standardization; monolithic motherboard fully integrated control, ease of maintenance, and avoids more board contacts too, the problem of high failure rate; so that the dust of the device, shock resistance, durability and long-term reliability can be guaranteed. 2, a comprehensive, intelligent protection system: with automatic pressure limiting, automatic current limiting and overvoltage, overcurrent, overheating, door switches, water pressure and water shut-off and other protective effects pipeline, as well as three-phase line-of-phase, lack of protection, the line voltage is too high, too low protection, with quenching machine chain protection (hardening machine is not ready, such as transformers, inductors and other cooling water is not sent, not power) and so improve the protection system makes equipment When not working to get timely and comprehensive protection. 3, high reliability / low failure rate: International Power and the overall structural design and circuit design synchronization, the main power devices and control panels are used worldwide chips imported brands, and all components are made of military grade aging screening process signals using shielded twisted pair transmission, to avoid interference. 4, the device has a wide adaptability, any band in the band 2-45KHz normal operation, the device starts first by high frequency scanning down from high and low, the natural frequency of the automatic tracking mode, to ensure that equipment start success rate of 100 %. It is very suitable for hardening applications, it is not only adapt to many varieties of small quantities, but also to adapt to a single species in large quantities. 5, the inverse transform device voltage zero crossing streams, to ensure power supply to run at high power factor and other characteristics. For large load changes hardening artifact has a wide adaptability, when loaded device also has a 100% success rate of start. 6, the power output with flexible soft cable connections than rigid connection, water connection cables for greater flexibility and energy savings. 7, equipment cooling circuit used in all brass faucets, convenient handling, easy cleaning up waterways, connecting pipes from Korea rubber pipes, burst water pipes to avoid leakage phenomenon. 8. In addition to cooling the monitoring system also uses a differential pressure gauges outside the controller only when the pressure difference between the inlet and outlet within the specified range, the power can only work, thus avoiding the water, water shut-off phenomenon. 9, with digital display voltmeter, ammeter, frequency meter, clear display and intuitive. 10, in order to facilitate the hardening flexibility, the device has three power channels can be realized with the machine with variable power heating process can also be simulated power control (ie, quantitative tools to a variable or an analog voltage to achieve the heating process variable power). 11, intelligent fault diagnosis system: instantly displays the working status and malfunction. 12, good harmonic suppression performance: To suppress harmonic interference generated by the power grid, in addition to the line circuit inductance wave peaceful anti-passive filtering, but also part of the rectifier and inverter join Boost circuit. 13, device components rational layout, easy maintenance, while the cabinet is equipped with lighting and sockets overhaul. Second, the main technical parameters 1. Rated Power Input: Three-phase four-wire (zero line, ground-sectional area of ??only 30mm2), 380V ± 5%, 50Hz; 2. Rated output power: divided into 100,160,200,250 , 300,350,500,600,700,1000KW several specifications; 3. Output frequency: divided 6,8,10,15,20,30,50kHz and broadband 1.5 ~ 50kHz; 4.
