Description

Audible and visual alarm grounding device

Technical Field

The utility model belongs to the technical field of the electric power fortune dimension, concretely relates to audible-visual alarm earthing device.

Background

When the grounding wire is fixed on the conductor to be grounded, the grounding wire is mostly realized through a grounding wire clamp. At present, a common grounding wire clamp is in a double-tongue hook type, the wire is clamped by the clamping force of an elastic tongue, but reliable clamping force is difficult to guarantee, the phenomena of virtual hanging such as poor hanging effect and the like can occur, the contact resistance between the grounding wire clamp and the wire is too large, the grounding quality is influenced, and the construction safety is influenced.

At present, after an operation and maintenance worker articulates a ground wire in a traditional mode, whether the ground wire is articulated well or not can be judged subjectively only through visual inspection, hidden dangers are left for field work due to the lack of scientificity and accuracy, and therefore, it is necessary to design a device capable of automatically monitoring the clamping condition of a ground wire clamp.

For example, patent document CN104716522A proposes an intelligent temporary grounding wire, which includes a hook, and a signal acquisition device is disposed on the top of the hook, and the signal acquisition device includes a control switch and a pressure sensor. The pressure sensor uses the semiconductor sensor to realize the calculation of the hanging reliability of the hook, the semiconductor sensor is fixed at the top of the hook, and after the grounding wire is hung well, the grounding wire is hung in the direction close to the vertical direction, so that the quality of the grounding wire and the copper wire connected to the hook is almost completely born by the semiconductor sensor. The patent judges whether the grounding wire is hung reliably by calculating the pressure of the semiconductor sensor (the gravity of the grounding wire), but cannot judge the clamping force of the hook on the lead; and the pressure signal detected by the pressure sensor is transmitted to the monitoring center, but the field operator cannot judge whether the hanging connection of the grounding wire is reliable.

Still like patent document CN110474180A provides an intelligence short circuit earthing device and ground connection method thereof, earthing device includes the action bars, the one end of action bars is connected with the conductor end, the conductor end includes the conductive metal couple, the symmetry is provided with the arc shell fragment on the conductive metal couple is close to the inside wall of opening part, the arc shell fragment extends and is close to each other gradually to the conductive metal couple department of bending, the arc shell fragment that the symmetry set up is close to conductive metal couple department of bending one side and keeps away from each other and form the cable groove, the cable groove forms the cable hole with the inboard of the department of bending of leading conductive metal couple, the downthehole conductive metal couple department of bending of cable is provided with first pressure sensor, first pressure sensor is connected with the control panel. When the grounding hook is used for pressing the wire, the pressure sensor is extruded to generate micro deformation, so that a pressure value is measured, and whether the grounding hook is firmly hung on the grounding wire or not is judged according to the pressure value. The first pressure sensor is arranged at the top end inside the conductive metal hook, and the stress of the first pressure sensor is the gravity of the grounding wire, so that the clamping force of the hook on the wire cannot be judged.
