Digital High-Power High-Frequency High-Voltage Switching Power Supply

Product name: High-Frequency Power Supply
Model : HPHD
Series : HPHD
Categories : Electrostatic Precipitator
Brand : Jiachuang Environmental Protection Technology Co., Ltd.

Special for electrostatic precipitator
HPHD digital high-power high-frequency high-voltage switching power
supply
HPHD digital high-power high-frequency high-voltage power supply is
a new high-frequency high-voltage switching power supply for power
supply dust collectors developed by Jiachuang Environmental 
Protection
Technology Co.,Ltd and an international company based on 
the increasing demand for atmospheric dust emission standards in 
the field of environmental protection. 

It adopts modern power electronics, modern cybernetics, computer and
network technology, semiconductor technology, mechatronics and other
modern comprehensive technologies and has independent intellectual 
property rights.

③ The power supply is changed from two-phase to three-phase, and 
  the power factor is increased from 0.7 to above 0.9, with less 
  grid pollution and good electromagnetic compatibility;
④ The volume and weight are reduced to less than 1/5, saving 
  materials and making transportation and installation very 
  convenient;
⑤ The control cabinet and transformer are integrated into one, 
  eliminating the need for a control room, saving space and 
  infrastructure costs;
⑥ Network control is adopted to achieve unmanned on-site 
  operation, high degree of automation and friendly 
  human-machine interface.

Compared with conventional ESP power supply, the product reduces 
dust emission by more than 50%
Adopting a new circuit topology,
New devices and high-frequency soft switching technology,
Improved dust removal efficiency
Can effectively solve the problem of low efficiency of electric
field dust removal
Can effectively solve the problem of poor operation of power plant
boilers
It can effectively solve the transformation of various boilers 
such as 135 tons, 75 tons, 65 tons, 50 tons, 35 tons, etc.
It adopts network control technology, with friendly human-machine 
interface and easy use and maintenance.
All power supply operations are centrally monitored by computers.
Operatorsset the operating parameters of each power supply, start
and stop, and display the operating status of each power supply 
(including voltage, current, temperature, faults, etc.) through 
the host computer and images.
The maximum monitoring distance of the host computer is 1.5 km,
and the number of power supplies is usually 15.
The use of network control technology realizes centralized 
monitoring of the system, and each power supply operates 
independently. 
Even if the communication network is disconnected, the power 
supply can still work normally without affecting the operation
of the electric field.
