Is the Pipeline Electric Heater Using an Automatic Control System
Pipeline Electric HeaterIs it using an automatic control system?
1. Electric heating adopts automatic control. The operator only needs to set the temperature parameters at startup and press the start button; the electric heater will automatically control the temperature without requiring dedicated personnel on duty.
2. It has conventional electrical protections such as short-circuit protection, overload protection, over-temperature protection, etc. 3. The control cabinet panel is equipped with voltage and current display, temperature display, indicator lights, buttons, etc.
4. Inside the control cabinet, there are circuit breakers, contactors, silicon-controlled power regulators, intermediate relays, etc.
Temperature Control
1. This system uses temperature controller ST1 to collect temperature signals. After PID calculation, it outputs voltage pulse signals, and the silicon-controlled rectifier adjusts the power output of the electric heater (0-100% power regulation) to ensurethe temperature accuracy of the heater.At the same time, the outlet temperature is transmitted to the remote DCS.
2. Temperature alarm: Temperature controller ST2 is used for over-temperature alarm. When the actual temperature exceeds the alarm set value, the heater alarms and self-locks, and the corresponding alarm light turns on. After the alarm condition is eliminated, press the reset button to restart.
3. The temperature switch is also used for over-temperature alarm. When the actual temperature exceeds the alarm set value, theheater alarms and self-locks, and the corresponding alarm light turns on. After the alarm condition is eliminated, press the reset button to restart.
Power Control
1. Power control uses a silicon-controlled power regulator for overall control, achieving 0-100% power regulation.
2. The silicon-controlled power regulator receives the voltage pulse signal output by the outlet temperature control instrument, and adjusts the heater output according to this signal to achieve 0-100% stepless power regulation, thereby precisely controlling the medium temperature.
