● The entire system’s electrical control cabinets utilize an indoor Rittal-style design with an IP40 protection rating. There are three control cabinets: cabinets 1 and 2 are MCC cabinets, and the final one is a PLC cabinet. This design effectively isolates interference between power and signal lines.
A fonte de alimentação principal dos armários de controlo elétrico é um sistema trifásico de cinco fios com uma tensão nominal de 380V CA, uma frequência nominal de 50Hz e uma corrente de carga máxima de 600A.
O fio preto no interior do armário é a linha de alimentação AC380V, o fio amarelo é a linha de controlo AC220V, o fio azul é a linha de controlo DC24V e a linha verde-amarela é a linha de terra.
● The main components inside the cabinet include a molded case circuit breaker, a miniature circuit breaker, an intermediate relay, an AC contactor, a frequency converter, and a PLC.
The ACS510 series inverter is used within the cabinet. This series is specifically optimized for fan and pump applications. Typical applications include constant-pressure water supply, cooling fans, subway and tunnel ventilators, and more.
The cabinet features an advanced operation panel, which connects to the internal inverter and allows for start/stop operation and displays operating status information.
The cabinet is equipped with a multi-function electric meter, providing real-time monitoring of three-phase voltage, current, and other parameters.
