Electrostatic precipitator high voltage control cabinet GGAJ02K\0.8A 72KV is the high voltage control part of high voltage electrostatic precipitator, high voltage electrostatic precipitator as a mature technology, relatively simple production, low maintenance costs of industrial flue gas purification equipment, for a long time, in the air pollution control industry has been * universal, * extensive promotion and application. However, with the improvement of environmental protection emission standards in recent years (the new standard is 50mg/Nm3), many active electrostatic precipitators cannot meet the new standards, and they have to undergo secondary transformation. At the same time, new projects are also facing new environmental protection pressures. The current widening, lengthening, enlargement and other traditional means are improvements in the structure of the body, with large investment and limited actual effects. Effective ESP transformation requires systematic research on coal combustion, body and power supply, especially for the old precipitator whose body has been finalized, equipped with advanced power technology, intelligent control and improvement of fine particles (PM2.5um) collection efficiency are the key to transformation. nbsp; 
As the core of electrostatic precipitator-high voltage power supply device, its equipment power supply capacity and principle characteristics to a large extent determine the efficiency and energy consumption index of electrostatic precipitator, GGAJ02K\0.8A 72KV high efficiency energy-saving full electric field dynamic optimization control two-phase high voltage power supply for electrostatic precipitator, using two-phase power supply, stable output waveform, high output average voltage (increased by 10%-20%), can effectively improve and improve dust removal efficiency; equipment power factor 0.94, conversion efficiency 70%, has the advantage of substantial energy saving (30%-50%).
 This   product adopts dynamic spark tracking technology combining software and hardware in design, large LCD (240X320 dot matrix) Chinese display, oscilloscope waveform display tracking function, * best slope energy saving and multiple mode control to adapt to different working conditions, voltage reduction vibration to improve operation effect, TCP/IP (Ethernet), MODBUS flexible dual communication mode, and has various perfect protection functions. It is a new type of high efficiency, energy saving and environmental protection.
The high voltage power supply equipment of the electrostatic precipitator is an updated product suitable for the conventional single phase power supply at present.
As a mature 32-bit DSP-controlled three-phase high-voltage power supply with full electric field dynamic optimization control in the world, this product has been successfully transformed and applied in 2 330MW thermal power units of No.1 and No.2 boilers of Zhejiang Energy Company Binhai Power Plant. KWEP series three-phase high-voltage power supply has opened up a brand-new energy-saving and emission-reducing technical field for the cause of electrostatic precipitator in China, with huge market potential and remarkable economic and social benefits.
2. Comprehensive voltage reduction and rapping control technology is conducive to keeping the pole plate and pole line clean and increasing the dust charging capacity to improve the dust removal efficiency.
GGAJ02K\0.8A 72KV 32-bit microcomputer controller has a very unique advantage, that is, the control of high voltage SCR and low voltage part of the rapping control integrated in the same controller, to achieve voltage control rapping (VCR, also known as voltage reduction rapping) function.
Voltage control rapping function refers to reducing the secondary voltage and current in the electric field (generally reducing the current to 0) at the same time of rapping operation, reducing or even closing the effect of electric field force, so that during rapping, the extremely fine dust with high specific resistance adsorbed on the polar plate and polar line is easily vibrated. By using the voltage control rapping function, the rapping effect can be obviously improved, the dust deposition on the polar plate is obviously reduced compared with that when the function is not used, so that the generation of anti-corona can be effectively reduced, the dust removal efficiency can be improved, and the frequency of rapping is reduced by several times, and the service life of the electrostatic precipitator body can be effectively prolonged.
It is worth pointing out that recently our company has added ash cleaning VCR, i.e., the boiler load is reduced to 60% to execute ash cleaning rapping and VCR compensation, i.e., the control concept of increasing power supply for another electric field during electric field rapping, to the voltage reduction rapping operation mode of KWEP controller. The dust removal system composed of KWEP controller has automatic progressive compensation function, i.e., when the voltage reduction rapping is implemented in the front stage electric field, the rear stage electric field will automatically adjust the operating parameters to replace the front stage electric field, thus ensuring the continuous and efficient operation of the dust remover, more effectively removing dust from the dust collecting plate and controlling the secondary flying problem caused by vibration, which highlights the characteristics of high efficiency and low consumption.
