Rectifier Cabinet LYKG of Plasma Ignition System

Rectifier Cabinet LYKG of Plasma Ignition System

Rectifier cabinet LYKG is a matching power supply device specially designed for Plasma Ignition and Combustion Stabilization System (PICS) in power plant (station). High-frequency switching power conversion technology and power conversion devices like IGBT from internationally well-known manufacturers are applied in the cabinet, which is designed with modular panel and can realize independent parallel operation with modular redundancy, having the advantages of high efficiency, large capacity, simple operation and easy maintenance. LYKG is equipped with Siemens S7-300 programmable control unit which is easy to operate. It can provide comprehensive on-line analog variables and switching values, with functions of perfect safety alarm, remote data transmission and communication interface, which can readily realize on-site operation, remote control and monitoring. This product includes two voltage grade series, LYKG-4 and LYKG-6, which can be used for plasma generators with loads under 400V and under 650V respectively. It applies to plasma generator of DLZ-200 and DLZ-DA-300.The power supply mainly includes three parts: rectifier module, centralized control module and PLC control unit. 
Rectifier module LYKG2-20 adopts high frequency switching power transformation and isolation technology to complete AC to DC transformation function. 
Centralized control unit LYKG2-20A-C, as the interface between PLC control unit and rectifier module, realizes constant current output control, current and voltage analog quantity collection, fault alarm collection, module start and stop control and other functions. 
PLC control unit mainly realizes logical control during system operation and external signal collection, provides comprehensive online analog quantity and switching value information, as well as remote data transmission and communication interface functions. 
Figure 1.2 and figure 1.3 are the external view of LYKG-4-120 rectifier cabinet and LYKG-6-180 rectifier cabinet with basic configurations respectively. For specific screen configuration, wiring terminal definition, external view, structure and dimensions, please refer to technical documents and drawings delivered with the product.

Features
High frequency switch power conversion and isolation technology.
High frequency inversion secondary rectification, high frequency transformer input and output isolation. 
Small size and high efficiency. 
Small space required for equipment and high density of power. 
Wide power regulation range. 
The output current is continuously adjustable, and the working current of the plasma generator is adjustable in a even wider range. 
Modular redundant parallel operation with high reliability. 
The modules are independent of each other and run in parallel. The maximum power output of the system can be changed by changing the number of rectifier modules. 
Plugging technology at module input and output terminal, convenient for maintenance. 
Plug type terminals are used for power input, output and control signals. 
Perfect protection and alarm function against input overvoltage / undervoltage, over temperature, output overcurrent, etc.
Comprehensive supply of system switching value and analog quantity information about output current/voltage, system air/water signal, and operation condition, etc.
