Brand : Jiachuang Environmental Protection Technology Co., Ltd.
Overview :
1. For the harsh working conditions of high wind speed in the electric field, high dust concentration, high specific resistance, and unstable dielectric breakdown strength, the GGAj02 series high-voltage control system can automatically adjust and increase the corona power. By increasing the frequency of electric field sparks, a large number of ions are released into the electric field, forcing the dust to increase in charge, and effectively overcoming the occurrence of the back corona phenomenon, so that its operating voltage is always maintained at the limit close to the breakdown voltage, thereby ensuring that a high electric field strength can be maintained under any working conditions, and improving the effective corona power and dust removal efficiency of the electric field.
2. It has the best dielectric strength recovery curve tracking method (two-fold segmented tracking method and step tracking method) for the computer to use according to different flashover and control operation modes.
3. Perfect current limit control and steady current characteristics
In actual operation, the breakdown voltage of the electrostatic precipitator is limited by the inter-pole spacing and dust characteristics. Users first hope to obtain the highest operating voltage, and then pursue the best corona current. The impedance of the dust collector varies with different working conditions, different inter-pole spacing, and different service life. Therefore, it is required that the current of the self-controlled high-voltage rectifier equipment should not exceed the capacity when automatically searching for the highest operating voltage, and the same is true when the load is short-circuited, which means that it should have a current limit control characteristic. When the equipment is running at a preset current, if the impedance of the dust collector changes, only the voltage is allowed to change accordingly, and the current should not deviate from the set value, so as to ensure the stable operation of the equipment.
4. The high-voltage power supply device provides the following power supply modes:
low flash frequency power supply mode;
intermittent
power supply mode;
pulse power supply mode; flash frequency tracking
power supply mode; ordinary tracking
power supply mode; peak tracking power supply mode;
5. The controller panel adopts Chinese LCD display, which can display the primary current, primary voltage, secondary current, secondary voltage, spark rate and other operating parameters, and can set various parameters. The parameter setting has a memory function, and the set parameters do not need to be reset after power failure. The output voltage and current parameters are steplessly adjustable within the range of 0-range.
When the system is powered on, the self-test program is executed to self-test the main chips. If the program is abnormally operated or terminated due to strong interference during operation, it can automatically restart and restore the normal operation of the system. The system anti-interference design uses the internationally advanced technology to ensure the high-quality operation of the equipment. If a fault occurs, the controller can display the type and nature of the fault in time.
6. It has the following fault protection functions:
short circuit protection, open circuit protection, overcurrent protection, impact protection, bias excitation protection, undervoltage protection, light and heavy gas, oil temperature over-limit protection and sound and light alarm, etc.
7. A serial RS485 standard remote communication interface is reserved for data communication with the host computer, transmitting operating parameters and status settings to the host computer, and various working modes can be set through the host computer. It can be started and stopped remotely. When the host computer is shut down, it can automatically switch to independent operation and directly accept the parameter settings of the operator.
8. According to needs, secondary voltage and secondary current transmitter outputs can be added, and the output is a DC4-20mA standard signal corresponding to the equipment capacity.
