● The entire system’s electrical control cabinets utilize an indoor Rittal-style design with an IP40 protection rating. There are four control cabinets: 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 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 1000A.
● The black wire inside the cabinet is the AC380V power line, the yellow wire is the AC220V control line, the blue wire is the DC24V control line, and the yellow-green line is the ground line.
● The main components inside the cabinet include a molded case circuit breaker, a miniature circuit breaker, an AC contactor, an intermediate relay, a frequency converter, a soft starter, and a PLC.
● Inside the cabinet Components from leading brands such as Schneider, Siemens, and Omron ensure system stability and a longer service life.
● All equipment controls feature manual and automatic functions, allowing for flexible mode switching to meet diverse control needs.
● The entire system utilizes the Siemens S7-1500 series CPU. Its fast response time, integrated CPU display panel, and corresponding debugging and diagnostic mechanisms significantly improve production efficiency and reduce costs.
● The control cabinet is equipped with a multi-function meter for real-time monitoring of three-phase voltage, current, and other parameters.
● A wireless communication module is built into the cabinet, enabling remote program modification and the viewing of real-time operating parameters and other information via a mobile app or web browser.
