Description

Insulator Replacement Brackets

technical field

The utility model relates to the technical field of power transmission, in particular to an insulator replacement bracket.

Background technique

In the operation of power distribution lines, due to the influence of various factors, the damage of insulators is inevitable. In order to ensure the reliability of power supply, the damaged insulators must be replaced. Power failure and replacement of insulators will have a great impact on the power supply capacity of the grid. Therefore, live replacement of insulators has become one of the main items of live work.

At present, there are mainly two methods for replacing insulators with electricity:

The first one is to place the unbundled wires directly on the cross-arm with insulation shielding. However, there are deficiencies in this method. Before work, the ground potential parts such as electric poles and cross-arms must be shielded. The workload is large, the operation steps are cumbersome, and the safety factor is low; Shaking caused by accidental touch can easily lead to dangerous accidents.

The second type is to insulate the wires hanging from the crane arm of the car. However, this method also has shortcomings. The load of the boom is limited, and now some lines have been insulated, the wires are too heavy, and the insulated wires with large spans are not suitable for use; The rotation is inconvenient and affects the flexible rotation of the insulating working bucket; at present, it is common to erect double circuits or multiple circuits on the same pole of the line, and at the same time, the safety distance is reduced, which limits the application of this method.

Based on the above analysis, the current working method cannot meet the working requirements of live replacement of insulators.

Utility model content

The utility model aims to solve at least one of the problems in the prior art.

One of the technical problems to be solved by the utility model is to solve the problem of safely replacing the insulator under electrified conditions.

In order to solve the above technical problems, the utility model provides an insulator replacement bracket, which includes a fixed base, an insulating connector and a wire slot; the fixed base is provided with a U-shaped groove, and the lower end is installed with a The upper end of the locking screw of the device is connected with a connecting rod; the lower end of the insulating connector is connected with the connecting rod, and the upper end is connected with a fixing seat; the wire clamping groove is fixed on the fixing seat.

Further, the insulating connector is made of a load insulator.

Further, the wire draw slot includes a U-shaped bracket and an L-shaped bracket, the U-shaped bracket is fixed on the fixing seat, and the L-shaped bracket is fixed on the U-shaped bracket.

Further, the upper end of the fixed base is fixed with a nut, the two ends of the connecting rod are provided with threads, the lower end of the connecting rod is threaded with the nut, and the upper end is threaded with the insulating connector.

The utility model has the beneficial effect of providing an insulator replacement bracket. The utility model has a firm structure and can securely fix the wires, which can meet the requirements of the live work method. KV insulators are replaced.

Of course, implementing any product of the present application does not necessarily need to achieve all the technical effects described above at the same time.
