VOC waste gas treatment system control cabinet

● The entire system’s electrical control cabinets utilize an indoor Rittal cabinet design with an IP40 protection rating. There are four control cabinets in total: cabinets 1, 2, and 3 are MCC cabinets, and the final one is a PLC cabinet. This design effectively isolates interference between power and signal lines.

● The main power supply to the electrical control cabinets is a three-phase, five-wire system with a rated voltage of AC380V, a rated frequency of 50Hz, and a maximum load current of 320A.

● The yellow, green, and red copper busbars inside the cabinets are the three-phase live wires A, B, and C. The yellow wire is the AC220V control wire, the blue wire is the DC24V control wire, and the yellow-green connection is the ground wire.

● The main components within the cabinet include molded case circuit breakers, miniature circuit breakers, intermediate relays, switching power supplies, switches, PLCs, and touch screens.

● Cabinet components are from renowned brands such as Schneider and Siemens, ensuring system stability and a longer service life.

● The entire system CPU utilizes a redundant architecture, enhancing functionality and reliability.

● All equipment controls feature manual and automatic functions, with flexible switching modes to meet diverse control needs.

● The cabinet features buttons, indicator lights, and an inverter operation panel. These panels, connected to the electrical components within the cabinet, display the operating status of the control cabinet and control the start and stop of equipment.

● A multi-function electric meter is installed on the cabinet, providing real-time information on three-phase voltage, current, and other parameters.

● All parameter values ​​on the PLC panel can be modified in real time, and all alarm information can be viewed on the alarm screen, making it easy to handle abnormal situations. In emergencies, the PLC cabinet’s emergency stop button enables rapid shutdown.
