Description

Technical Field

[0001] The invention belongs to the electric power industry, and in particular relates to a protective device for live replacement of electric energy meters. Background Art

[0002] In the electric power industry, maintenance and replacement of equipment are common occurrences. However, during the maintenance or replacement process, live work is sometimes required, which poses a safety hazard to the workers. Some workers have been injured during the work.

[0003] In order to reduce safety hazards, in the existing live point operation process, the measure adopted is to wrap the exposed live parts of the wire with insulating tape after removing the power line, and then carry out the operation. After the operation is completed, the insulating tape needs to be removed again when rewiring, and the wire needs to be reconnected. However, this process cannot completely solve the problem of electric injuries caused by touching the live parts, and the operation process is quite cumbersome, requiring repeated wrapping and removal of the tape on the wire, which takes a long time and has low operation safety.

[0004] Therefore, a device is needed to solve the problems of possible danger, complicated process and long operation time when replacing the electric energy meter under power. Summary of the invention

[0005] The purpose of the present invention is to address the defects of the current traditional process of wrapping wire ends with insulating tape, and to provide a protective device for replacing electric energy meters under power, so as to solve the problems of easy touching of live parts, long operation time, and complicated procedures when replacing electric energy meters under power, so that workers' work becomes safe, simple and reliable. The device is simple to use, reduces the contact between hands and live parts, greatly reduces the danger, and improves work efficiency.

[0006] The protective device for live replacement of electric energy meters described in the present invention comprises an upper clamp and a lower clamp, wherein the upper clamp is provided with an upper rubber clamp pad, and an upper wire clamp groove is provided on the upper rubber clamp pad, and the structure of the lower clamp is the same as that of the upper clamp and is symmetrically arranged, wherein a lower rubber clamp pad is provided on the lower clamp, and a lower wire clamp groove is provided on the lower rubber clamp pad; the upper clamp is fixedly connected to the upper clamp handle; and the lower clamp is fixedly connected to the lower clamp handle.

[0007] One or more wire clamping grooves are arranged on the rubber clamping pad.

[0008] When a wire clamping groove is provided on the rubber clamping pad, the specification of the wire clamping groove is set to 2.5 mm, 4 mm or 6 mm.

[0009] When a plurality of wire clamping grooves are arranged on the rubber clamping pad, the specifications of the wire clamping grooves on the same rubber clamping pad are one or more specifications of 2.5 mm, 4 mm or 6 mm.

[0010] When replacing the electric energy meter under power, put the wire into the wire clamp slot and clamp it.

[0011] The upper and lower clip handles are equipped with anti-slip grids on the outside.

[0012] An upper insulating sleeve is arranged on the outer side of the upper clamp, and a lower insulating sleeve is arranged on the outer side of the lower clamp.

[0013] The insulating sleeve is fixedly connected to the clamp by pasting. When the upper insulating sleeve or the lower insulating sleeve is damaged, the upper insulating sleeve or the lower insulating sleeve can be replaced separately.

[0014] An upper insulating rubber pad is arranged between the upper clamp and the upper rubber clamp, and a lower insulating rubber pad is arranged between the lower clamp and the lower rubber clamp.

[0015] Upper brackets are arranged on both sides of the upper clamp handle; and lower brackets are arranged on both sides of the lower clamp handle.

[0016] The upper bracket and the lower bracket are arranged correspondingly, and the upper bracket and the lower bracket are hinged.

[0017] The upper rubber clamping pad or the lower rubber clamping pad is movably connected to the upper clamping head or the lower clamping head. Since the wire clamping groove often clamps the wire, it is easy to become loose and damaged. When it is damaged, the upper rubber clamping pad or the lower rubber clamping pad can be replaced separately.

[0018] Support handles are arranged inside the upper clamp handle and the lower clamp handle to prevent the upper clamp handle and the lower clamp handle from being broken or damaged due to excessive force or long use time.

[0019] The upper clamp handle and the lower clamp handle are symmetrically arranged.

[0020] The protective device for replacing the electric energy meter under power is made of insulating material as a whole.

[0021] During the operation, each time a live wire is removed from the meter, the wire is placed in the wire clamp groove and clamped, and then other wires are removed and installed.

[0022] This device is provided with a wire clamping groove in the rubber clamping pad at the clamping head. When in use, the live wire is removed from the meter, the wire is placed in the wire clamping groove and bitten, so that there is no exposed point of the live wire, which greatly reduces the risk of electric shock. The device is easy to operate. Compared with the traditional process, it eliminates the process of wrapping the wire end with insulating tape and disassembling the insulating tape, greatly reducing the work steps and improving safety.

[0023] According to different on-site conditions, the protective device for live replacement of electric energy meters of corresponding specifications can be selected according to the wire diameter. It is also possible to select a rubber clamping pad with one standard wire clamping groove or a rubber clamping pad with multiple standard wire clamping grooves.

[0024] The present invention uses a mechanized insulation wrapping tool to wrap the live wire, thereby realizing live working in a safe situation.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] Compared with the method of wrapping the live wire end with insulating tape, the method of the present invention only needs to place the live wire end in the reserved groove and clamp it to achieve the same insulation effect. The method of the present invention is simple, reduces the contact between the hand and the live body, greatly reduces the danger, and improves work efficiency.

[0027] The insulating device is made in the form of a clip. On the one hand, it is convenient and safe. On the other hand, the mechanical principle is simple and workers can learn and use it easily.

[0028] The present invention is safer and more efficient when replacing an electric energy meter while it is energized. BRIEF DESCRIPTION OF THE DRAWINGS
