One tow two system solution

Views:

In the field of medium and high voltage solid state soft start, our company can produce series of standard starter, mine general type, high prototype and other soft starter cabinets, which can provide comprehensive product solutions for customers.

Description:
1. When designing the soft start system, comprehensive consideration should be given to factors such as rated voltage, rated power, grid capacity, and load type of the motor. The following system diagram only shows the small and medium power motor as an example. When the motor power is large, the vacuum contactor in the figure should be designed as a vacuum circuit breaker, and the number of cabinets will increase accordingly.
2. When the motor power is >2000KW, it is necessary to add a star point cabinet.
One-to-two systems can be divided into three types:
? Single power supply, two motors run at different times, see Figure 1, Table 1
? Single power supply, two motors can run at the same time, see Figure 2, Table 2
? Dual power supply, two motors running at different times, see Figure 3, Table 3
