Description

Ring main unit outgoing line grounding device

Technical Field

The utility model relates to the field of grounding devices, in particular to a ring main unit outgoing line grounding device.

Background

In the 10kV cable power supply network, T-shaped terminal bolts are generally selected for connection, and the conductive part of the terminal is 3-5cm in a T-shaped insulating sleeve. The T-shaped insulating sleeve of the cable connection stub is protected at the front end by a cap during normal operation. Because the T-shaped insulating sleeve is compact in structure, the traditional horizontal grounding wire hanging mode cannot be carried out in the ring main unit transformer, the ring main unit and the cable branch box, and therefore the grounding wire must be hung on an overhead line or a transformer substation far away from a working section.

However, the power safety regulations prescribe that a working ground wire must be installed at both ends of the service equipment. When the ring main unit, the cable junction box and the ring main unit are changed to be overhauled, and when the ring main unit, the cable junction box and the ring main unit are changed to be unable to be provided with the grounding wire, the grounding wire is required to be arranged to the upper ring main unit or the overhead line, the problem of enlarging the power failure range exists, and the potential safety hazards such as climbing operation can be brought by hanging the grounding wire on the overhead line. The connecting ground wire hangs at the distance and not only can lead to the operator to run back and forth, still can reduce work efficiency, increases intensity of labour, increases the power failure maintenance time.

Therefore, it is necessary to provide a new ring main unit outlet grounding device to solve the above technical problems.
