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, using grounding circulating current sensors to pick up grounding circulating current signals is an important means of online monitoring of railway traction power supply system cables. Therefore, grounding circulating current sensor installation devices on railway traction power supply system cables are important cable accessories. Currently, existing grounding circulating current sensor installation devices on railway traction power supply system cables are still connected to the cables via binding. The contact area between the binding connectors and the railway traction power supply system cables is limited, thus affecting the installation effectiveness of the grounding circulating current sensor.

[0003] This utility model, through its technical features of clamp connection with railway traction power supply system cables and base connection with grounding circulating current sensors, effectively explores and studies the technical problem of connecting to railway traction power supply system cables via a binding method.

[0088] This utility model has the following features:

[0089] 1. Due to the design of the clamping plate assembly, the external closing displacement component, and the installation component, the clamping plate assembly enables the extended area friction connection of the peripheral side of the railway traction power supply system cable. The external closing displacement component enables the clamping plate assembly to retract inward. The installation component enables the installation of the grounding circulating current sensor, achieving clamp connection with the railway traction power supply system cable and base connection with the grounding circulating current sensor. This solves the technical problem of connecting to the railway traction power supply system cable by binding, thus improving the installation effect of the grounding circulating current sensor.

[0090] 2. Due to the design of the first clamping plate 1 and the second clamping plate 2, the railway traction power supply system cable is clamped and fixedly connected.

[0095] 7. Due to the design of the cylindrical shell 5, the first screw 3 and the second screw 4 are supported by extended shims.

[0096] 8. Because the design limits the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of this utility model, and is not a technical feature obtained by formula calculation or by a limited number of experiments. The experiment shows that the technical feature of the numerical range has achieved very good technical effect.

[0097] 9. Due to the design of the technical features of this utility model, and the combined effect of the individual and collective technical features, experiments have shown that the performance indicators of this utility model are at least 1.7 times that of existing performance indicators, and it has been evaluated as having great market value.
