Intelligent relay power supply for rail transit engineering (section water pump)

There is a transformer substation located in the subway train parking lot and a transformer substation located at the subway station, with a distance of about 4.5km between them. They are connected through a section tunnel, which is located under the mountain and has a drainage pump room in the middle. Whether it is from the station or the parking lot, the distance of low-voltage power supply exceeds 2km, which is a tricky problem. The distribution scheme of installing intelligent relay power supply in the interval communication channel has solved the problem of low-voltage long-distance power supply.
In subway engineering, there are often low-voltage long-distance power supply problems in section air shafts, vehicle bases, etc. The use of intelligent relay power supply solutions can safely, reliably, and economically solve the problem of low-voltage long-distance power supply.
