Description

Insulating sleeves for maintenance of low-voltage electrical equipment

technical field

The utility model relates to an electric power transmission line maintenance tool, in particular to an insulating sleeve used for low-voltage electric equipment maintenance.

Background technique

Most of the low-voltage power distribution equipment is repaired by power failure. After the knife switch is disconnected, the maintenance personnel use ordinary metal sleeves or wrenches to turn the nuts to repair the low-voltage equipment. Because the equipment in the equipment box is compact, there are many wires, and the operating space is narrow, the upper end of the ordinary sleeve is fixed with the standpipe, and the force arm of the wrench also has a certain length, which affects the operation, which is extremely inconvenient and reduces the work efficiency. . Moreover, most of the existing low-voltage distribution boxes in urban areas adopt an insulating structure, and it is inconvenient to install grounding wires during maintenance, which brings potential safety hazards to maintenance personnel.

Contents of the invention

The purpose of this utility model is to provide an insulating sleeve for maintenance of low-voltage power equipment. The insulation sleeve for maintenance of low-voltage power equipment should solve the problem of narrow operating space in the low-voltage power distribution box in the prior art. The technical problems of inconvenient operation and inconvenient setting of grounding electrodes cause potential safety hazards.

The purpose of this utility model is achieved through the following technical proposals: it includes a cylindrical standpipe, the front end of the standpipe is provided with an inner hexagonal hole matched with a nut, an insulating sleeve is provided on the outer casing of the standpipe, and a through hole is provided at the upper end of the standpipe. The through hole of the diameter line is provided with an operating rod in the through hole, and the through hole and the operating rod are in clearance fit, and the outer circumference of the operating rod is provided with an insulating sleeve.

Stoppers are arranged at both ends of the operating rod.

The stopper is made of nuts arranged at both ends of the operating rod.

An insulating plastic layer is arranged in the through hole at the upper end of the riser.

The upper end of the standpipe is provided with a plug in the shape of a semicircle.

Compared with the prior art, the utility model has positive and obvious effects. In the utility model, an insulating sleeve is provided on the outer periphery of the standpipe and the operating rod in the insulating sleeve used for the maintenance of low-voltage electric equipment, which can carry out low-voltage live work, and the through hole at the upper end of the standpipe is pierced with an operating rod. , The operating rod can slide in the through hole to avoid the equipment and wires in the distribution box blocking the operating space; there is an insulating plastic sleeve between the operating rod and the standpipe, which improves the insulation on the one hand and facilitates sliding on the other.

Description of drawings

Fig. 1 is a schematic diagram of an insulating sleeve used for maintenance of low-voltage power equipment of the present invention.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail through embodiment.

As shown in Figure 1, the insulation sleeve used for the maintenance of low-voltage power equipment of the present invention includes a cylindrical standpipe 1, and the front end of the standpipe 1 is provided with an inner hexagonal hole 2 matched with a nut, and a tube outside the standpipe is covered An insulating sleeve 3 is provided, and the upper end of the standpipe 1 is provided with a through hole that runs through its diameter line. The through hole is pierced with an operating rod 4. The through hole and the operating rod 4 are clearance fit, and the outer circumference of the operating rod 4 is provided with an insulating sleeve. . The two ends of the operating rod 4 are provided with stoppers, and the stoppers are made of nuts 5 located at the two ends of the operating rod. An insulating plastic layer 6 is provided in the through hole at the upper end of the standpipe 1 . The upper end of standpipe 1 is provided with a plug 7 that is a semicircular surface, and the plug 7 can prevent bumps in use.

In actual use, it is necessary to design a variety of standpipes with hexagonal hole specifications, but only one operating rod is needed, and the operating rod and the standpipe can be disassembled or assembled through the nuts at both ends of the operating rod.
