Khởi động mềm - Soft Starters

Tại sao phải dùng Dòng khởi động mềm Simens 3RW55 Failsafe soft starters

Simens 3RW55 Failsafe soft starters được trang bị các chức năng tối ưu, bộ khởi động mềm Failsafe Hiệu suất cao SIRIUS 3RW55 tự tin xử lý ngay cả các hoạt động khởi động và dừng khó. Nhờ điều khiển mô-men xoắn cải tiến, thiết bị có thể được sử dụng cho các ổ điều khiển drive có công suất từ ​​5,5 kW đến 560 kW (ở 400 V).
Tại sao phải dùng Dòng khởi động mềm Simens 3RW55 Failsafe soft starters
Bộ khởi động mềm Failsafe 3RW55 cải tiến có một đầu vào kỹ thuật số an toàn không tích hợp để kết nối trực tiếp DỪNG KHẨN CẤP, do đó bao phủ các ứng dụng SIL 1 STO. HMI có thể tháo rời (với màn hình màu, giao diện cục bộ và khe cắm cho thẻ nhớ micro SD) và các mô-đun giao tiếp plug-in (PROFINET, PROFIBUS, EtherNet / IP và Modbus) mang lại sự linh hoạt tối đa.


Với công nghệ chuyển mạch lai hiện đại, bộ khởi động mềm Failsafe của SIRIUS 3RW55 cung cấp khả năng chuyển mạch hiệu quả để sử dụng lâu dài, tiết kiệm năng lượng.

Note:

The service factor or measurement inaccuracies have been taken into account, for example, for the selection of the specified motor starter protectors/circuit breakers; the specified short-circuit breaking capacities Iq in kA are covered by combination tests. Smaller motor starter protectors/circuit breakers from the same series can be used at any time as smaller ones trip more quickly in the event of a short circuit (unchanged short-circuit breaking capacity) and thus protect the soft starter in any case. The dimensioning of the short-circuit components must match the connected three-phase motor, the short-circuit and overload requirements of the application, and the line protection for the cables used.

In inside-delta circuits, a gR class full-range fuse could not provide the semiconductor protection of the delta-connected soft starter with a short-circuit breaking capacity that is adequate for practical use. In this case, we recommend using aR class partial-range fuses for semiconductor protection for type of coordination "2", see next table.

For CLASS 10 applications, as an alternative to the gG class full-range fuses for cable and line protection 3NA3 (F1), 3RV2/3VA motor starter protectors/circuit breakers can also be used, possibly with reduced short-circuit breaking capacity, see Table "Motor feeders according to IEC with 3RV2 / 3VA motor starter protectors (without semiconductor protection)". In these cases, optional line contactors can be dispensed with.
