Abstract

The invention discloses a low-voltage side ground wire hanging device, and relates to the field of ground wire hanging tools. The lower end of the outgoing line of a 0.4 kV circuit breaker is not provided with a special ground wire hanging end, only a ground wire is hung at a lap joint cable bolt, and the ground wire is hung infirmly at the lap joint cable bolt; the ground wire needs to be hung ineach power failure, hanging operation is frequent, consumed time is long, efficiency is low, the space allowance of the wire outlet side of the low-voltage circuit breaker is small, and many potential safety hazards exist in ground wire erection. The device comprises a grounding rod, a grounding wire lapping plate, a replaceable bolt connecting part and a pluggable insulating operating handle. The ground wire hanging end is fixed on the low-voltage wire outlet end bolt through the bolt connecting part, the ground wire is lapped on the ground wire lapping plate, the insulated pluggable operating handle is convenient to repeatedly share, the structure is simple, the operation is convenient, the safety is high, the defect of insufficient space of the wire outlet side of the low-voltage circuit breaker is avoided, the lapping safety distance of the ground wire is increased, grounding wires are stable and reliable in lap joint, high in lap joint speed and high in efficiency.

Description

technical field

[0001] The invention relates to the field of grounding wire hanging tools, in particular to a low-voltage side grounding wire hanging device. Background technique

[0002] The types of 0.4kV low-voltage outlets include: low-voltage outlets in power distribution rooms, low-voltage outlets in box-type transformers, outlets in low-voltage cable branch boxes, and 0.4kV outlets in column-mounted transformers. At present, there is no dedicated grounding wire hanging end at the lower end of the 0.4kV circuit breaker outlet, resulting in the following problems:

[0003] 1. There is no special grounding wire hanging end at the lower end of the outlet of the 0.4kV circuit breaker, only the grounding wire is hung at the lap cable bolt, and the grounding wire hanging here often falls off and is not firm.

[0004] 2. The grounding wire needs to be installed every time there is a power outage. Operators frequently install the grounding wire, and the longest time spent in ...

Examples

Embodiment Construction

[0026] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] Such as Figure 1-2 As shown, a grounding wire hanging device on the low-voltage side includes a grounding rod 1, a grounding wire lap plate 2 connected to the grounding rod 1 and perpendicular to the axial direction of the grounding rod 1, and a connecting plate at the front end of the grounding rod 1 for connecting An operating handle 4 is provided at the rear end of the bolt connecting portion 3 to the low-voltage outlet bolt and the rear end of the grounding rod 1 .

[0028] In order to replace the bolt connection part 3, the ground rod 1 includes a front rod part 101 positioned at the front side of the ground wire bonding board 2 and a rear rod part 102 positioned at the rear side of the ground wire bonding board 2. The front rod part 101 is connected to the bolt connection part 3 detachable connection between. The fron...
