AC 800PEC series PVD164A2059 3BHE014340R2059 high performance control system.

Aluminum uses the AC 800PEC equipment controller. The AC 800PEC main controller communicates with the controller through PEC-PEC optical fiber. The optical link (100 μs) can be mastered independently of the control unit to allow urgent operation (full smooth current control, in urgent mode, there is no AC 800 PEC, Only used in combination with DCS800 pre-magnetization) software that can contain predictive maintenance functions such as open circuit, overcurrent, undervoltage and overvoltage maintenance package-newly developed OPC (open circuit maintenance) independent PLC (programmable logic controller), controlled shutdown in maintenance events with AC 800PEC main controller function or independent maintenance panel as main equipment, You don't need to travel immediately → reduce the disturbance to you. Potline load swing detection and load shedding application software integrates the function of on-load tap changer quick tapping function. In order to avoid DC current overload disturbing the special potentiometer based on AC 800PEC series, the maximum power can be adjusted (permed)-to avoid excessive power consumption, and support your generator to adjust your process with stable maximum DC voltage.

Electric arc furnace uses stable arc detection and different control forms (constant current, stable power or stable resistance) to quickly connect to PQS electrode for adjustment; The functions of anode hydraulic system control include: manual electrode control (analog or digital), rapid electrode improvement function (with or without independent rapid rising valve), active arc ignition function, active arc reignition function, adaptive electrode control behavior according to the furnace or voltage fluctuation measurement (stability index calculation) of thermal stage superposition integral control circuit, arc to roof detection/ Maintenance of arc to roof maintenance order during arc flashover hydraulic oil pressure monitoring and electrode maintenance collapse exploration high pressure detection back pressure valve control logic voltage to ground monitoring roof voltage monitoring electrode active lifting function instruction (optional distance or orientation) blocking valve control electrode and electrode speed limit arm maintenance future function-active proportional valve linearization check-active proportional valve linearization-stable dynamic voltage set point control melting processElectric arc furnace uses stable arc detection and different control forms (constant current, stable power or stable resistance) to quickly connect to PQS electrode for adjustment; The functions of anode hydraulic system control include: manual electrode control (analog or digital), rapid electrode improvement function (with or without independent rapid rising valve), active arc ignition function, active arc reignition function, adaptive electrode control behavior according to the furnace or voltage fluctuation measurement (stability index calculation) of thermal stage superposition integral control circuit, arc to roof detection/ Maintenance of arc to roof maintenance order during arc flashover hydraulic oil pressure monitoring and electrode maintenance collapse exploration high pressure detection back pressure valve control logic voltage to ground monitoring roof voltage monitoring electrode active lifting function instruction (optional distance or orientation) blocking valve control electrode and electrode speed limit arm maintenance future function-active proportional valve linearization check-active proportional valve linearization-stable dynamic voltage set point control melting process

Chemical use: OLTC step compensation control in lubrication process-IDC step compensation of lubrication current and current change during boosting. OLTC power factor compensation can include predictive maintenance function. Software maintenance package includes:-DC over-current maintenance-communication over-voltage and under-voltage maintenance-communication phase imbalance maintenance -12-pulse system imbalance maintenance system. DC grounding fault detection can be realized by 3-volt meter with SIL 3-level process pulse. The voltage at the input of the module loop crosses the voltage sag. Electrolytic extraction industry (copper and zinc): IDC current step compensation, which is used for the current change during lubrication and boosting. The power factor compensation of OLTC can include predictive maintenance functions: DC overcurrent maintenance, communication overvoltage and undervoltage maintenance, communication phase imbalance maintenance, 12-pulse system imbalance maintenance system, main DC current control unit of parallel rectifier, DC open-loop detection during operation, DC open-loop maintenance, and the graphitization process of DC power supply in graphite electrode factory requires a lot of DC voltage and current change power supply. Providing a constant DC power supply to the process does not take into account the changing process resistance-probably due to the very fast cycle time AC 800PEC controller. Ability to add customized process recipes and modify them in order on the operation panel to meet specific customer requirements.
