We usually use many, many electric motors, and many people are big when they encounter it. Now I will organize it for everyone. The specific match is simple.
Note: Consider the soft start of softness above 1.22kW. After the soft startup, the start current is considered 4 times the normal current (when there is no soft start, the start current is considered at 7 times the normal current).
That is: when the soft startup is started, the current set current: IQD = 1.2 × 1.8 × 7 × 7 × IE = 15.2IE or IQD = 2.16 × i starts from starting up
When there is a soft start, the instantaneous set current: IQD = 1.2 × 1.8 × 4 × IE = 8.7Ie
2. The VV cable is considered to be laid in the air, and the YJV22 cable is considered to be buried directly (the soil thermal resistance coefficient is considered as 2K.M/W), the operating temperature of the BV wire conductor is at 70 degrees, and the ambient temperature is 35 degrees (4 guide lines).Essence
3. Conduct pipes should be considered by 1 bending.
the second one
How about it, it is very simple, it is simple to understand.
