Fault diagnosis and condition-based maintenance of SCR power controllers are effective ways for power systems to improve equipment management, and they are the direction of future development in power production. It is therefore worth understanding the structure, principle, common faults and hazards of the product before deciding whether to purchase it and how to use and maintain it.
The SCR power controller uses imported German SEMIKRON (SKKT series) thyristor modules. By controlling voltage, current and power it achieves precise temperature control, and with its advanced digital control algorithm it optimizes the efficiency of electrical energy use, playing an important role in saving electricity.
SCR power controllers are widely used in the following fields:
- Electric furnace industry: annealing furnaces, drying ovens, hardening furnaces, sintering furnaces, crucible furnaces, tunnel furnaces, melting furnaces, box and pit furnaces, roller furnaces, vacuum furnaces, trolley furnaces, kilns, aging furnaces, bell furnaces, atmosphere furnaces, laboratory furnaces, salt bath furnaces, resistance furnaces, mesh belt furnaces and high-temperature furnaces.
- Machinery: packaging machinery, injection molding, heat-shrink equipment, extrusion, food machinery, textile machinery, tempering equipment, plastics processing, powder metallurgy machinery, petrochemical machinery and infrared heating.
- Glass industry: glass fiber, glass forming, glass melting and float glass production.
- Automotive industry: paint drying and thermoforming.
- Energy-efficient lighting: tunnel lighting, street lighting, studio and stage lighting.
- Chemical industry: distillation and evaporation, preheating systems, pipeline heating, petrochemical processes and temperature compensation.
- Other industries: diamond press heating, high-power magnetizing and demagnetizing equipment, aviation power regulation, central air-conditioning electric heater control, crystal production, annealing baths for picture tube lines, and constant-voltage / constant-current / constant-power control.
