Khởi động mềm - Soft Starters

Siemens 3RW40 soft starters - Những điều cần quan tâm khi dùng

Bộ khởi động mềm SIRIUS 3RW40 Basic Performance thích hợp cho việc khởi động và dừng mềm của động cơ không đồng bộ ba pha.
Siemens 3RW40 soft starters - Những điều cần quan tâm khi dùng
Nhờ điều khiển hai pha, không chỉ dòng điện được giữ ở giá trị nhỏ nhất trong cả ba pha trong toàn bộ thời gian khởi động mà còn loại bỏ các thành phần dòng điện một chiều gây nhiễu. Điều này không chỉ cho phép khởi động hai pha của động cơ lên ​​đến 55 kW (ở 400 V) mà còn tránh các cực đại dòng điện và mô-men xoắn xảy ra, ví dụ với bộ khởi động wye-delta.

Bộ khởi động mềm SIRIUS 3RW40 thích hợp để khởi động động cơ chống cháy nổ với loại bảo vệ "tăng cường an toàn" EEx e theo Chỉ thị ATEX 94/9 / EC.

Note:

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.

For CLASS 10 applications, as an alternative to the gG class full-range fuses for cable and line protection 3NA3 (F1), 3RV2 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 motor starter protectors (without semiconductor protection)". In these cases, optional line contactors can be dispensed with.
