The temporary cable consists of three single-phase flexible cables. The utility model uses temporary cables to bridge the overhead lines in the work area, so that the overhead lines in the work area are powered off, and the staff repair and maintain the overhead lines in the power failure, and the temporary cables provide power for users in the work area, ensuring that users No power outage or less power outage, reduce economic loss.

Description

A device for troubleshooting overhead lines without power failure

1. Technical field: The utility model relates to a power fault processing device, in particular to a device for processing faults of overhead lines without power failure.

2. Background technology: With the development of the national economy and the improvement of people's living standards, the society has higher and higher requirements for the reliability of power supply. Due to the limitations of various conditions, it is impossible for most users to achieve dual power supply. The necessity of comprehensive non-stop operation of distribution lines.

The 10KV distribution line is an important part of the power distribution network, and it is the infrastructure that directly faces the users. Due to the complexity of the distribution line network and the characteristics of large coverage area, it covers every corner of the power supply business. However, the distribution network is prone to failure due to low insulation level, atmospheric overvoltage, natural aging of equipment or other external factors, and the workload of maintenance is heavy. Whether it is social or economic benefits, forced outage of the 10KV distribution network will cause failure. Estimated loss.

3. Contents of the utility model:

The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art, and provide a device for handling faults of overhead lines with reasonable design, simple structure, high efficiency and reduced power loss loss without power failure.

The technical scheme of the utility model is: a device for handling faults of overhead lines without power failure, which includes support rods and temporary cables, load-bearing steel cables are set up between the support rods, pulleys are arranged on the load-bearing steel cables, temporary The cables are arranged on the trolley, and the two ends of the temporary cables are respectively connected to the overhead lines at both ends of the working area and the overhead lines in the working area are disconnected and powered off, and the temporary cables are respectively connected to the user circuits in the working area through branch lines .

The temporary cable consists of three single-phase flexible cables.

The beneficial effects of the utility model are:

1. The utility model uses temporary cables to bridge the overhead lines in the work area, so that the overhead lines in the work area are powered off, and the staff repair and maintain the overhead lines in the power outage, and the temporary cables provide power for users in the work area. Ensure that users have no or less power outages and reduce economic losses.

2. The utility model erects load-bearing steel cables between the support rods, and a pulley is set on the load-bearing steel cables, which is convenient for fast and light erection of temporary cables, with high work efficiency, short power-off time and low power-off loss.

3. The utility model is reasonable in design, simple in structure, high in efficiency and reduces power failure loss, and has good economic and social benefits after popularization.

4. Description of drawings:

Fig. 1 is the structural representation of the utility model.

Five. Specific implementation methods:

Embodiment: Referring to Fig. 1, among the figure, 1-circuit breaker, 2-overhead line, 3-wire pole, 4-user, 5-support rod, 6-temporary cable, 7-bearing steel cable, 8-pull block.

The device for troubleshooting overhead lines without power failure includes support rods 5 and temporary cables 6, load-bearing steel cables 7 are erected between the support rods 5, pulleys 8 are arranged on the load-bearing steel cables 7, and temporary cables 6 are set on the pulleys 8 , easy to move, the two ends of the temporary cable 6 are respectively connected to the overhead lines 2 at both ends of the work area and the overhead line 1 in the work area is disconnected and powered off, and the temporary cables 6 are respectively connected to the circuits of the users 4 in the work area through branch lines.

Temporary cable 6 consists of three single-phase flexible cables. Of course, according to needs and site conditions, the supporting rod 5 may not be erected, but the original wire rod 3 (or other parallel wire rods) is used to erect the load-bearing steel cable 7, so as to reduce construction time and cost.

During use, use the connecting rope and the traction tool to move the temporary cable 6 along the load-bearing steel cable 7 by the winch, so as to realize rapid erection and shorten the power failure time. After the maintenance of the overhead line 2 is completed, the temporary cable 6, the support rod 5 and the load-bearing steel cable 7 are removed, and then the circuit breaker 1 is removed, and the overhead line 2 is connected for normal power supply.
