Problems solved by technology

However, the electrical control system used in the current electrocoagulation treatment equipment cannot limit the voltage and current. Therefore, there are inevitably troubles in the phase sequence wiring of the three-phase input power supply, and there is no problem with the electrical control system such as under-phase, over-current, abnormal, and over-current. Therefore, in the process of wastewater treatment, there is too low voltage generated by wastewater conductivity to convert heat energy to the circuit module, resulting in overheating and damage to the circuit module; the sudden rise of voltage and current causes the impact circuit to affect the pulse signal; And the unbalanced three-phase current input affects the triggering of the pulse frequency, resulting in damage to the thyristor, resulting in the failure of the electrocoagulation treatment equipment to operate normally
