technical field

The utility model relates to a structural device in the electric power industry, in particular to a branching structure and a branching device.

Background technique

In the domestic power industry, with the continuous improvement of power system specifications, the corresponding transformation of old power equipment is also in progress. Especially in the transformation process of power grid distribution, from the state of no electric meter in each household, to the state with centralized electric meter, and then to the state of electric meter entering the household. Under different conditions, correspondingly, different changes have been made to the wiring and wiring methods between main line poles, household poles, and users. Especially in the vast rural areas, because the users are relatively scattered, due to the state of no electricity meter or the state of centralized electricity meters, it is easy to cause the household cables from the household pole to the user to be too long, and there are too many installation nodes. After long-term use, the cable sheath Aging can easily cause safety hazards such as electric leakage.

According to the industry requirements of the current power system, it is necessary to implement household meter installation. The current method used is to drain the current from each phase of the 0.4KV three-phase main line pole and pass it overhead through the branch pole, and send it to the user. Therefore, the household cables are too concentrated, and to repair or replace one of the household cables, it is necessary to cut off the power consumption of multiple users or even a wider range of users.

Therefore, according to the aforementioned situation, it can be judged that the existing wiring and branching methods cause inconvenient maintenance because there is no obvious disconnection point. According to existing wiring and branch line mode, need to disconnect live wire and zero line between the three-phase main line pole to the nearest household branch pole, just can carry out the operation of maintenance and replacement household branch line.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is made further description.

Example 1:

This embodiment provides a branching structure applied in the electric power industry. The structure includes a lead-in end and multiple branching ends, and each branching end can respectively disconnect and close the cable. The lead-in end of the branch line structure is connected to one of the 0.4KV three-phase main line poles, and the multiple lead-out ends of the branch line structure are connected to multiple household lines. When in use, each lead-out end closes a household cable, and during maintenance, each lead-out end can disconnect the corresponding household cable.

Further, the plurality of branch terminals are arranged in a line. This arrangement is simple and reliable, and is suitable for use with a line distribution pole with fewer users.

Further, the plurality of branch terminals are arranged in a matrix. This arrangement can be suitable for the branch poles with many users and is practical.

Further, the lead-in end can break and close the cable.

The technical solution provided by this embodiment is not only suitable for use in vast rural areas, but also has obvious breakpoints, which provides convenience for maintenance, replacement and transformation of household cables.

Example 2:

This embodiment provides a line distribution device according to Embodiment 1. The device includes a support rod and an insulating post, and the line branching structure is detachably connected to the support rod through the insulating post. Among them, the supporting rod is used for fixed connection with the branching rod, and plays a role in supporting the weight of the household cable. The insulating column adopts various methods in the prior art, and besides having an insulating effect, it can also support the sub-line structure and household cables.

Further, it also includes a centralized wire clamp, which is installed on the insulation column in parallel with the distribution structure; one end of the centralized wire clamp can disconnect and close one cable, and the other end can disconnect and integrate multiple cables. One end of the concentrated line clamp is connected to the zero phase on the 0.4KV three-phase main line pole, and the other end is connected to the zero phase of multiple household lines.

Further, it also includes a plurality of insulating porcelain bottles, and the plurality of insulating porcelain bottles are detachably installed on the support rod. Insulating porcelain bottles can be wrapped around both live and neutral cables. At the same time, the function of household division can also be enhanced through the position of the insulating porcelain bottle.
