HP-80 plasma flame spraying system power supply:
 |
Plasma spraying main power supply is a new type of constant current mode power supply, 80KW inverter power supply control, communication with optical fiber and PLC communication, greatly improve the stability of the power supply, control power voltage fluctuation plus or minus 1V, current plus or minus 1A, is currently the best plasma power supply in China. Using liquid crystal display, digital operation; And can realize the corresponding protection of the spark count, can fully meet the power supply on the basis of the realization of reasonable and rapid arc extinguishing function; With perfect data acquisition system, real-time monitoring of power supply voltage, current, cooling temperature, conductivity, pressure, power, etc., timely feedback and analysis of data, play a timely role in gun protection. Its main structure, working principle and usage instructions are as follows. |
