The base station power cabinet is a key equipment ensuring continuous power supply to base station devices, with LLVD (Load Low Voltage Disconnect) and BLVD (Battery Low Voltage Disconnect) being two important protection mechanisms in the power cabinet.
Since the servers in this room manage both cell and fixed-line network communication, they must be guarded against overvoltages. Servers usually use 48 V DC voltage. The power lines going into the server rooms are defended using type 2 surge protection designed for DC applications.
Assume the rated voltage of a communication base station's battery is 48V, with the BLVD threshold set to 42V. When the mains power fails and the battery starts supplying power, the power system continuously monitors the battery voltage through the voltage detection circuit.
Protection in the context of electrical power systems involves measures and equipment designed to detect and respond to abnormal operating conditions, faults, and disturbances. Its main objectives are: 1. Power system protection is essential for maintaining the reliability, safety, and stability of electrical power systems.
