Description

Technical Field

[0002] Railway traction power supply system cables are crucial components for realizing railway informatization and electrification. In 27.5kV traction substations of electrified railways, power supply cables are laid in various ways, including direct burial, conduit installation, tunnel wall mounting, cable trench laying, or laying along bridges. These complex working environments and the inconvenience of maintenance can lead to cable faults, thus affecting the safe power supply for train operation. To ensure the safe operation of the cables, online monitoring of the railway traction power supply system cables is conducted using electrical signals. Therefore, online grounding current monitoring boxes for railway traction power supply system cables are an important cable accessory. Currently, there is no dedicated online grounding current monitoring box for railway traction power supply system cables; instead, ammeters are directly installed within the enclosure. This limitation, stemming from the signal transmission limitations of the ammeter, affects the effectiveness of online monitoring of electrical signals on the railway traction power supply system cables.
