Connection method of cold channel data room load and hot channel computer room current load
We know that if the voltage applied to the load exceeds the rated voltage of the load and is too high, the electrical appliance will be damaged quickly; back
However, if the voltage applied to the load is lower than the rated voltage of the load, the role of the load cannot be fully played. Therefore, when using any electrical appliance, it is necessary to make the rated voltage of the load equal to the power supply voltage.
For three-phase load, if the rated voltage of each phase of the load is equal to the power line voltage, the load shouldConnect it into a star, and then connect it with the power supply, as shown in Figure 1-4-15. When the rated voltage of each phase of the load is equal to the power supply voltage, the load should be connected into a triangle and then connected to the power supply, as shown in Figure 1-4-16.

For example, the power line voltage is 380 V. If the rated voltage of each phase of the load is 220 V, the load should be connected into a star; When the rated voltage of each phase of the load is 380 V, it should be connected into a triangle. Regardless of whether the load is star or delta connection, the generator winding can be connected into a star or delta.
