As China's economy grows, the application of motors is increasingly widespread, and the methods of motor starting are gaining more attention. Generally speaking, motor usage power exceeds...30KWIt's time to use a motor soft starter; otherwise, it will severely affect the operation of other equipment in the power grid and cause damage to the motor itself. It can be said that "there are many benefits to using a soft starter on a motor."!Specific benefits.

The Dangers of Direct Full Voltage Starting of Electric Motors and the Benefits of Soft Starters

　　⒈ Voltage fluctuations in the power grid have affected the operation of other equipment on the same grid.

When starting a交流motor at full voltage directly, the starting current will reach the rated current of4~7When the motor's capacity is relatively large, the starting current can cause a sharp drop in grid voltage, affecting the normal operation of other equipment on the same grid.

When using a soft starter cabinet for motors, the starting current is typically around the rated current.2~3There was no Chinese content provided for translation.10%Internally, the impact on other equipment is minimal.

　　⒉ Impact on the Power Grid

The impact on the power grid is primarily manifested in two aspects:

The high current surge from the direct startup of ultra-large motors is almost equivalent to the impact of a three-phase short circuit on the power grid, often causing power oscillations and destabilizing the grid.

② The starting current contains a large amount of high-order harmonics, which can cause high-frequency resonance with the parameters of the power grid circuit, leading to faults such as relay protection misoperation and automatic control failure.

The soft starter cabinet for motors significantly reduces the starting current during startup, completely eliminating the aforementioned impacts.

　　⒊ Motor insulation damage, reduces motor lifespan

High current generates Joule heat, which repeatedly acts on the external insulation of the wire, accelerating its aging and reducing its lifespan.

High current-induced mechanical forces cause the wires to rub against each other, reducing the insulation lifespan.

③When the high-voltage switch closes, the oscillation of the contacts can cause operation overvoltage on the motor stator winding, which sometimes reaches the applied voltage.5Multiple times the normal voltage, such high overvoltage can cause damage to the motor insulation.
