Section 4: Overview of 600KW Stainless Steel Air Electric Heating Element Control System

Overview of Intelligent Fully Automatic Control System:

The electric heating intelligent fully automatic control cabinet is a specialized temperature control unit designed for our company's various electric heating equipment to form an electric heating system. It integrates main circuit protection, temperature measurement and control, as well as control of flow, pressure, working current, voltage, and system pumps into a single integrated unit.

The temperature control system in an electric heating system is an essential component.

2. Requirements for the Intelligent Fully Automatic Control System:

Ambient Temperature: -15℃ to 40℃

(2) Relative Air Humidity: ≤95%

(3) Installation Location: Non-explosive areas, non-corrosive, indoor installation

(4) Protection Class: IP55 (Outdoor), IP23 (Indoor)

(5) Altitude: Above Sea Level

(6) Power: 400-230V 50Hz

3. Structural Features of the Smart Fully Automatic Control System:

Control cabinets are available in two types: suspended and floor-standing. Floor-standing cabinets can be customized with front or front-and-rear doors as per customer requirements. Control cabinets can be categorized as outdoor or indoor based on the installation location. One cabinet can be combined to install multiple control units, allowing for the measurement and control of multiple sets of electric heating equipment.

4. Features of the Intelligent Fully Automatic Control System:

(1) The main circuit of the electrical control cabinet is protected against short-circuits, overloads, and disconnection of heating elements by an automatic air switch.

(2) The electrical cabinet can be electrically interlocked with the relevant level controller or oil pump control unit.

(3) An independent over-temperature alarm system is equipped, which will shut down the electric heater and output a contact signal when the internal temperature of the heater exceeds the set value, without automatic reset.

(4) Offers multiple interlock interfaces with DCS (analog, switch).

(5) Features manual/automatic seamless switching.

(6) Achieve full automatic monitoring.

5. Working Principle of the Intelligent Fully Automatic Control System:

New technologies in comprehensive disciplines such as heat transfer, chemical engineering, thermodynamics, thermal structure engineering, electrical engineering, instrumentation, automatic control engineering, mechanical engineering, and software and hardware engineering for computer systems are the result of our company's long-term dedication to the development and research of electric heating equipment, guided by practical experience in the detection, control, optimization, and amplification of the electric heating process. These products possess the following characteristics:

Simultaneously detect and control the heating temperature, pressure*, and medium flow* of the medium;

*Equipped with automatic control of key parameters such as temperature, pressure, and motor soft start-up control.

Equipped with temperature detection*, pressure detection*, flow detection*, current and voltage detection*, medium liquid level height*, insulation resistance detection*.

The temperature, pressure*, and flow* limits can be set with upper and lower limits, and it features an overload alarm function.

All alarm incidents can be recorded and reviewed.

Equipped with over-temperature, low flow, three-phase unbalanced resistance, leakage, and automatic shutdown alarms.

Temperature, pressure, current, voltage, flow rate, etc., can all be set to automatic, manual, or off modes.

Parameters such as medium temperature, pressure, current, and voltage can be automatically tracked and controlled according to the set curves.

Each parameter features a PID adjustment process display, including setpoint, real-time value, PID setpoint, upper and lower limit values, curve tracking display, manual/automatic switching, online setting, etc.; all set parameters can be restored to their original state upon power outage and subsequent restart.

Historical data and curves for various parameters can be saved for years (requires a supervisory computer to be implemented); key parameters are synchronized into the database for easy data analysis at any time.

User-friendly interface, featuring a switch between over a dozen monitoring screens.

The system features various interrelated controls: temperature and power interrelation control, system pump and flow interrelation control, current, voltage, and electric heater interrelation control, etc.; it also includes real-time display of the operational process, data recording, data analysis (bar graphs, line charts, and batch reports), output printing, password management, abnormal analysis, and alarm functions. The interface is fully in Chinese with detailed help instructions. The record screen can simultaneously display up to 8 different curves in various colors, and more curves can be displayed sequentially as needed.

Remote monitoring of the electric heater's operating status is available via a local area network or the internet.*

Parameters of each detection and control loop can be set and corrected online manually on the screen, including temperature, power, and temperature sensor calibration, as well as the calibration of pump flow rates; the operation features multi-level password protection and different operation permissions allocation.

Automatically records the startup time, shutdown time, power outages during automatic operation, outage duration, and power restoration time for electric heaters.

The software system features adaptive and self-diagnostic capabilities; abnormal situations can be automatically reported and protected according to customer settings.

Large LED displays with critical parameters at the site*; display temperature and pressure—clear, critical parameters at a glance.
