Description

Special lead wire fixing bracket for live work in distribution network

Technical field:

The utility model relates to the field of auxiliary tools for electric power, in particular to a special lead wire fixing bracket for live work in a distribution network.

Background technique:

In the operation of replacing a 10 kV pole-mounted switch with load, removal and installation of the switch leads and how to deal with the suspended switch leads are the key points of the project and the main danger points. When removing and installing switch leads, strive to be fast and accurate, and keep a safe distance of not less than 0.4 meters between the suspended switch leads and live equipment.

At present, when removing the switch leads, the operator fixes the switch leads and the main wires with an insulating rope buckle, then removes the parallel groove clamp, hangs the removed switch leads in the air, and when installing, puts the switch leads and the main wires together. Fix it with parallel groove clamps. However, there are four problems: one is to fix the switch lead wire and the wire with an insulating rope buckle before removing the switch lead wire. Since the connection of the insulating rope buckle is a soft connection, after the wire clamp is loosened, the switch lead wire can only rely on manpower Control, due to sudden "looseness", may cause the switch lead wire and the ditch wire clip to fall off, which does not meet the safety requirements for live work; second, the suspended switch lead wire cannot be reliably fixed, and the disconnected wire ends swing freely, and the safety distance is not easy to control. There are safety risks; the third is that when installing the switch leads, the switch leads can only be lifted and fixed by manpower, which cannot be installed quickly, and there are safety risks; fourth, such operations are all operated by a single person, and the operation is extremely inconvenient.

Invention content:

In order to overcome the problems existing in the prior art, the utility model provides a special lead wire fixing bracket for live work of the distribution network, which is used for temporarily fixing the lead wire of the switch in the work of replacing the switch on the pole with load, which is convenient, fast, safe and reliable.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A special lead wire fixing bracket for live work in distribution network, which is mainly composed of main wire clamp, insulating pull rod and switch lead wire clamp. One end of the hinge Ⅰ is combined and linked together, and the other end is fixed by the eyebolt Ⅰ to form a closed circular tube Ⅰ; the switch lead wire clip is composed of two semicircular tube slots Ⅱ, and the two semicircular tube slots One end of Ⅱ is connected together by hinge Ⅱ, and the other end is fixed by eyebolt Ⅱ to form a closed circular tube Ⅱ; the ends with nuts of main wire clamp and switch lead wire clamp are respectively connected by reinforcing nut and insulation The tie rods are fixedly connected together.

The connection angle between the main lead wire clip and the insulating pull rod is 90°, and the connection angle between the switch lead wire clip and the insulation pull rod is 30°, so as to meet the normal operating conditions of the switch lead wire.

Both the above-mentioned semicircular pipe groove I and semicircular pipe groove II are made of aluminum alloy.

The inner diameter of the above-mentioned circular tube I is provided with insulating rubber to prevent damage to the wires.

The inner diameter of the annular tube II is provided with insulating rubber, and the insulating rubber is provided with horizontal stripes, which can prevent damage to the wires.

The above-mentioned insulating pull rod is made of insulating resin material, has a length of 0.5 meters and a diameter of 50 mm.

The beneficial effects of the utility model are:

The utility model adopts the method of first fixing and then dismantling the special lead wire fixing bracket for live work of the distribution network, which effectively solves the problems existing in the switch operation on the load replacement column, eliminates the risk factor of relying on manpower, and conforms to the live Operational safety requirements, easy to use, safe and reliable.
