The installation position of the power surge protector refers to where to install the power surge protector. The output terminal of the 10KV transformer generally needs to be equipped with a power surge protector, but it is not necessary to install it. This is because the high-voltage side of the transformer is equipped with a power surge protector. If the transformer is in the communication building, the line from IE to the low-voltage power distribution cabinet of the building is very short, and the low-voltage power distribution cabinet is installed with a power surge protector.
Lightning protector installed.
The low-voltage power distribution cabinet is the power control switch of the entire communication building, and the low-voltage power distribution cabinet should generally be equipped with a power surge protector. For communication equipment or other equipment, when they are far away from the power surge protector of the previous level (such as the floor distribution cabinet), for example, more than 20m, it is generally necessary to install a power surge protector.
If the DC line of the communication power supply is long, a power surge protector can be installed. The installation of the power surge protector should be considered according to the lightning damage situation, the lightning protection capability of the equipment and other factors, and it cannot be installed everywhere. This is neither economical nor scientific.
